LAUNDRY DETERGENT AND/OR FABRIC CARE COMPOSITIONS COMPRISING CHEMICAL COMPONENTS LINKED TO A CELLULOSE BINDING DOMAIN

Field of the Invention

The present invention relates to a chemical entity comprising more than one chemical components linked to a Cellulose Binding Domain (CBD).

Background of the invention

Modern laundry detergent and/or fabric care compositions contain various detergent ingredients having one or more purposes in obtaining fabrics which are not only clean, fresh and sanitised but also have retained appearance and integrity. Therefore, detergent components such as perfumes, soil release agents, fabric brightening agents, fabric softeners, chelants, bleaching agents and catalysts, dye fixatives and enzymes, have been incorporated in laundry detergent and/or fabric care compositions. In using such detergent components, it is important that some of these compounds deposit on the fabrics so as to be effective during or after the laundering and/or fabric care process.

One specific example is the use of cellulase enzymes for the treatment of cotton- containing fabrics which largely consist of cellulose. The cellulose structures are depolymerized or cleaved by cellulases into smaller and thereby more soluble or dispersible fractions. This activity in particular on fabrics provides a cleaning, rejuvenation, softening and generally improved handfeel characteristics to the fabric structure. However, it has been difficult to incorporate cellulase enzymes into modern detergents in an effective manner. In that regard, those skilled in the art have sought to use minimal amounts of cellulase to their fullest effectiveness by ensuring that most, if not all, of the cellulase enzyme comprised in the detergent composition deposits on the fabric. For example, optimum cellulases would generally have a binding domain especially suitable for celluloses. In this way, most of the cellulase enzyme included in the detergent composition deposits or otherwise binds to the fabric during the laundering cycle to achieve its desired results.

Similarly, it would be desirable to have laundry detergent and/or fabric care compositions in which chemical components are also modified to ensure deposition onto the fabrics for improved and/or new performances.

Accordingly, there remains a need to formulate laundry detergent and/or fabric care compositions wherein the chemical components have improved deposition on fabrics, which results in improved performance during typical washing / fabric care cycles. There is also a need to ensure that chemical components remain on the fabric or fibre during the additional steps of rinsing and during wear. There also remains a need for such components to be formulated in an cost-effective manner.

The above objectives have been met by formulating laundry detergent and/or fabric care compositions comprising a chemical entity comprising more than one chemical components linked to a cellulose binding domain. It has been surprisingly found that such chemical entities more readily affix or otherwise come into contact with the fabric, thereby resulting in new, increased, enhanced and/or more cost-effective performance of the chemical component at the fabric surface or when released during or after the laundry and/or fabric care process.

Enzymes linked to Cellulose Binding Domains are described in the art : WO 91/10732 describes novel derivatives of cellulase enzymes combining a core region derived from an endoglucanase producible by a strain of Bacillus spp., NICMB 40250 with a CBD derived from another cellulase enzyme, or combining a core region derived from another cellulase enzyme with a CBD derived from said endoglucanase, for improved binding properties. WO94/07998 describes cellulase variants of a cellulase classified in family 45, comprising a CBD, a Catalytically Active Domain (CAD) and a region linking the CBD to the CAD, wherein one or more amino acid residues have been added, deleted or substituted and /or another CBD is added at the opposite end of the CAD. WO95/16782 relates to the cloning and high level expression of novel truncated cellulase proteins or derivatives thereof in Trichoderma longibrachiatum comprising different core regions with several CBDs. WO97/01629 describes cellulolytic enzyme preparation wherein the mobility of the cellulase component may be reduced by adsorption to an insoluble or soluble carrier e.g. via the existing or newly introduced CBD. WO97/28243 describes a process for removal or bleaching or soiling or stains from cellulosic fabrics wherein the fabric is contacted in aqueous medium with a modified enzyme which comprises a catalytically active amino acid sequence of a non-cellulolytic enzyme selected from amylases, proteases, lipases, pectinases and oxidoreductases, linked to an amino acid sequence comprising a cellulose binding domain and a detergent composition comprising such modified enzyme and a surfactant. WO98/00500 discloses a composition comprising a protein deposition aid having a high affinity for fibres or a surface and having a benefit agent attached / adsorbed thereto.

However, none of these documents disclose a chemical entity comprising more than one chemical components linked to a cellulose binding domain, for providing new, increased, enhanced and/or more cost-effective performance of the chemical components.

Summary of the invention

The present invention relates to a chemical entity comprising more than one chemical components linked to an amino acid sequence comprising a Cellulose Binding Domain.

The present invention further relates to laundry detergent and/or fabric care compositions comprising one or more of such chemical entities. These compositions provide new, increased, enhanced and/or more cost-effective performance of the chemical components. The present invention also relates to a method of treating a fabric with a chemical entity, comprising the steps of :

(i) selecting a chemical component to be attached to a cellulose binding domain; (ii) applying the chemical entity to the fabric.

The present invention further relates to the use of a cellulose binding domain to deposit a chemical component onto a fabric wherein the chemical component is attached to the cellulose binding domain.

The present invention finally relates to a process for attaching a chemical component to a cellulose binding domain comprising the steps of in any order : (i) reacting the chemical components to the linking region; and/or (ii) reacting the linking region with the cellulose binding domain.

Detailed description of the invention

The object of the present invention is to increase and/or enhance the performance and cost effectiveness of chemical components. This object is achieved by the formulation of a chemical entity which comprise more than one chemical components linked to an amino acid sequence comprising a cellulose binding domain. It has been surprisingly found that such chemical entities more readily affix or otherwise come into contact with the fabric, thereby resulting in new, increased and/or enhanced performance of the chemical component at the fabric surface or when released during or after the laundry and/or fabric care process. Accordingly, this allows to formulate compositions in a more cost- effective manner.

The present invention relates to a chemical entity having a ratio of chemical components to Cellulose Binding Domain unit (CBD) higher than 1. This can be achieved by :

- The linking of all chemical components directly to a selected cellulose binding domain. Said cellulose binding domain is selected to comprise in its amino acid sequence, at least one Lysine amino acid. Lysine amino acid(s) and the terminal amino acid will provide suitable attachment points for chemical components. - The linking of at least one chemical component directly to the cellulose binding domain and at least one chemical component indirectly to said cellulose binding domain via a linking region. In this instance, at least one chemical will be attached to the reactive group of an amino acid comprised in the sequence of the cellulose binding domain. At least another chemical component will be linked to said CBD via a linking region.

- The linking of all chemical components indirectly to a cellulose binding domain via a linking region comprising more than one reactive site suitable for the linking of a chemical component, hereinafter referred to as "polyreactive linking region".

Also encompassed in the present invention are combinations of these different options, i.e., chemical entities wherein the chemical components are linked directly and/or indirectly via a linking region and/or polyreactive linking region to one or more cellulose binding domains and/or one or more selected cellulose binding domains, i.e. :

- A chemical entity wherein all the chemical components are linked directly to the CBD;

- A chemical entity wherein at least one chemical is linked indirectly via a linking region to the CBD; - A chemical entity wherein at least one chemical component is linked directly to the CBD and at least one chemical component is linked indirectly via a linking region to the CBD;

- A chemical entity wherein all the chemical components are linked indirectly via a linking region to the CBD; - A chemical entity wherein said linking region is a polyreactive linking region;

- A chemical entity wherein said amino acid sequence comprising a cellulose binding domain comprises at least one Lysine amino acid.

Depending on the intended activity of the attached chemical component, said chemical components can be linked permanently or temporarily to the CBD, linking region and/or the polyreactive linking region. Therefore, the present invention further encompasses chemical entities wherein the chemical component is linked to the CBD, linking region and/or polyreactive linking region by a weak bond. Said weak bonds are cleaved during or after the wash or fabric care process, allowing the release of the attached chemical component(s). Preferably, the perfume component, insect control agent, hygiene agent will be linked via a weak bond.

Identical or different chemical components can be linked to a CBD. The chemical components encompassed in the present invention are preferably selected from the group consisting of perfumes, hygiene agents, insect control agent, softener compounds, soil release polymers, bleaching agents, dye fixatives agents, brighteners and/or mixtures thereof. More preferred components are the perfume components, insect control agents, hygiene agents and/or bleaching agents.

In addition to these chemical entities, the compositions of the present invention can comprise the same chemical components unmodified.

The linking region

The term "linking region" is intended to indicate a region that adjoins the CBD and connects it to the chemical components. The linking region is an intermediate between the chemical components and the amino acid sequence comprising a cellulose binding domain. This linking region comprises a moiety that will covalently bind to the CBD and one or more reactive group available to attach a chemical component.

If encompassed in the chemical entity of the present invention, suitable are the linking regions characterised by having at least one attachment point for a chemical component and at least one attachment point to the cellulose binding domain. Preferably, the linking regions of the present invention will encompass at least one attachment point to the cellulose binding domain and more than one reactive group available to attach a chemical component, hereinafter referred to as "polyreactive linking region".

Suitable linking regions are :

1) Poly acrylic acid/ maleic acid and/or mixtures thereof wherein one of the acid moiety is covalently bond to a NH2 group present in the amino acid sequence of the CBD. The other acid units are the reactive groups available as potential attachment groups for chemical components via their alcohol/amine groups.

2) Poly vinyl alcohol polymers. These polymers can still comprise or not the moiety containing the polymerisation initiator. - Without the acid moiety containing initiator of polymerisation, this polymer can be linked for example, to the reactive group of aspartic or glutamic acid present in the amino acid sequence of the CBD via an esterification reaction. The poly vinyl alcohol polymer does further comprise hydroxyl reactive groups available for attachment of acid/aldehyde containing chemical components. - With an acid moiety containing initiator of polymerisation, this acid moiety of the initiator of polymerisation of the polymer for example, can be linked for example, to a NH2 group present in the amino acid CBD sequence. The poly vinyl alcohol polymer does further comprise hydroxyl reactive groups available for attachment of acid/aldehyde containing chemical components.

3) Also suitable are amine-containing compounds having the following general structure : B-(NH2)_n; wherein B is a carrier material, and n is an index of value of at least 1. Preferred B carriers are inorganic or organic carriers.

By "inorganic carrier", it is meant carrier which are non- or substantially non carbon based backbones. Among the inorganic carriers, preferred inorganic carriers are mono or polymers or organic-organosilicon copolymers of amino derivatised organo silane, siloxane, silazane, alumane, aluminum siloxane, or aluminum silicate compounds. Typical examples of such carriers are: organosiloxanes with at least one primary amine moiety like the diaminoalkylsiloxane [H2NCH2(CH3) 2Si]O, or the organoaminosilane (C6H5) 3SiNH2 described in: Chemistry and Technology of Silicone, W. Noll, Academic Press Inc. 1998, London, pp 209, 106).

Mono or polymer or organic-organosilicon copolymers containing one or more organosilylhydrasine moiety are also preferred. A typical example of such a class of carrier material is the N,N'-bis(trimethylsilyl)hydrazine (Me3Si) 2NNH2 described in: The OrganoSilicon Chemistry Second international Symposium, Pure and Applied Chemistry, Vol, 19 Nos 3-4, (1969).

The following are also preferred mono or poly silazanes and which are exemplified by the 1 ,1 ,1 ,3,3,3,-hexamethyl-2-phenyldiaminosilyldisilasane [(CH3) 3Si] 2NSi(C6H5)NH2) 2 described in: OrganoSilicon Compounds, 1965, V. Bazant and al. Academic Press). Still other preferred examples of polymer silicone derivatives are the cyclic 1 ,1 ,5,5,7,7,711 ,11-Octamethyl-3-9-bis-[2-(2- aminoethylamino)-ethyl]-1 ,5,7,11-tetrasila-3,9-diaza-6,12-dioxacyclododecane and the Hexaethoxydiamino cyclotetrasiloxane (C6H5) (NH2) 2Si4O4, id, Vol 2 part 2, p 474, p454). Preferred amino functionalized inorganic polymeric carriers for use herein are polyaminoalkyl polysiloxanes. Typical disclosure can be found in JP 79,131 ,096, and EP 058 493. Still other inorganic polymeric carriers suitable for use herein are the amino functionalized polydi-alkylsiloxanes, as described in EP 150 867 and having the general formula:

Typical amines having organic carrier include aminoaryl derivatives, polyamines, aminofunctional polymers, aminoacids and derivatives, substituted mono-, oligo- and poly amino saccharides, substituted amines and amides, dendrimers, and glucamines.

Of course, the amine compound can be interrupted or substituted by linkers or cellulose substantive group. A general formula for this amine compound may be represented as follows:

wherein each m is an index of value 0 or at least 1 , and n is an index of value of at least 1 as defined herein before. As can be seen above, the amine group is linked to a carrier molecule as defined by classes hereinafter described. The primary amine group is either directly linked to the carrier group or via a linker group L. The carrier can also be substituted by a R^* substituent, and R^* can be linked to the carrier either directly or via a linker group L. Of course, R* can also contain branching groups like e.g. tertiary amine and amide groups.

It is important for the purpose of the invention that the amine compound comprises at least one primary amine group to react with a chemical component of the present invention to form the reaction products. Of course, the amine compound is not limited to having only one amine function. Indeed, more preferably, the amine compound comprises more than one amine function, thereby enabling the amine compound to react with several chemical components of the present invention. For example, reaction products carrying mixed perfumes aldehyde(s) and/or ketone(s) can be achieved, thereby resulting in a mixed release of such fragrances.

Most of the compounds described in the classes of amine compounds hereinafter will contain at least one substituent group classified as R*. R^* contains 1 to 22 carbon atoms in the main chain and optionally can be an alkyl, alkenyl, or alkylbenzene chain. It can also contain alicyclic, aromatic, heteroaromatic or heterocyclic systems, either inserted into the main chain or by substitution of an H atom of the main chain. Further, R^* can either be linked to the carrier B material or via a linker L, as defined herein before. In this instance, L can also be -O-.

R* can be attached to the benzene ring via a linker L. The benzene ring can be substituted by other aromatic ring systems including naphtalene, indole, benzimidazole, pyrimidine, purine, and mixtures thereof. Preferably, the R^* is attached to the benzene ring in its para position.

Typical amino-benzene derivatives have the following formula:

Preferred amino-benzene derivatives have the following formula:

Preferred amino-benzene derivatives are alkyl esters of 4-amino benzoate compounds, preferably selected from ethyl-4-amino benzoate, phenylethyl-4- aminobenzoate, phenyl-4-aminobenzoate, 4-amino-N'-(3-aminopropyl)- benzamide, and mixtures thereof.

3.2-Polyamines

The polyamines of the invention need to have at least one, preferably more than one free and unmodified primary amine group, to react with a chemical component of the present invention. In the polyamines, H can be substituted by R*, optionally via a linker group L. Additionally, the primary amine group can be linked to the polymer end via a linker group L.

The polyamines compounds suitable for use in the present invention are water- soluble or dispersible, polyamines. Typically, the amino-functional polymers for use herein have a molecular weight between 150 and 2^*10⁶, preferably between 400 and 10⁶, most preferably between 5000 and 10⁶. These polyamines comprise backbones that can be either linear or cyclic. The polyamine backbones can also comprise polyamine branching chains to a greater or lesser degree. Preferably, the polyamine backbones described herein are modified in such a manner that at least one, preferably each nitrogen of the polyamine chain is thereafter described in terms of a unit that is substituted, quaternized, oxidized, or combinations thereof.

For the purposes of the present invention the term "modification" as it relates to the chemical structure of the polyamines is defined as replacing a backbone -NH hydrogen atom by an R' unit (substitution), quaternizing a backbone nitrogen (quaternized) or oxidizing a backbone nitrogen to the N-oxide (oxidised). The terms "modification" and "substitution" are used interchangeably when referring to the process of replacing a hydrogen atom attached to a backbone nitrogen with an R' unit. Quaternization or oxidation may take place in some circumstances without substitution, but substitution is preferably accompanied by oxidation or quaternization of at least one backbone nitrogen.

The linear or non-cyclic polyamine backbones that comprise the amino-functional polymer have the general formula:

*' I

[R₂N-R]n+ι -[N-R]_m-[N-R]_n-NR₂ The cyclic polyamine backbones that comprise the amino-functional polymer have the general formula:

I R' | R

[R2N-R]n-k+l— [N-R]_m-[N-R]_n-[N-R]k-NR₂ The above backbones prior to optional but preferred subsequent modification, comprise primary, secondary and tertiary amine nitrogens connected by R "linking" units.

For the purpose of the present invention, primary amine nitrogens comprising the backbone or branching chain once modified are defined as V or Z "terminal" units. For example, when a primary amine moiety, located at the end of the main polyamine backbone or branching chain having the structure

H2N-[R]- is modified according to the present invention, it is thereafter defined as a V "terminal" unit, or simply a V unit. However, for the purposes of the present invention, some or all of the primary amine moieties can remain unmodified subject to the restrictions further described herein below. These unmodified primary amine moieties by virtue of their position in the backbone chain remain "terminal" units. Likewise, when a primary amine moiety, located at the end of the main polyamine backbone having the structure -NH2 is modified according to the present invention, it is thereafter defined as a Z "terminal" unit, or simply a Z unit. This unit can remain unmodified subject to the restrictions further described herein below.

In a similar manner, secondary amine nitrogens comprising the backbone or branching chain once modified are defined as W "backbone" units. For example, when a secondary amine moiety, the major constituent of the backbones and branching chains of the present invention, having the structure

H

— ΓN-R]— is modified according to the present invention, it is thereafter defined as a W "backbone" unit, or simply a W unit. However, for the purposes of the present invention, some or all of the secondary amine moieties can remain unmodified. These unmodified secondary amine moieties by virtue of their position in the backbone chain remain "backbone" units.

In a further similar manner, tertiary amine nitrogens comprising the backbone or branching chain once modified are further referred to as Y "branching" units. For example, when a tertiary amine moiety, which is a chain branch point of either the polyamine backbone or other branching chains or rings, having the structure

is modified according to the present invention, it is thereafter defined as a Y "branching" unit, or simply a Y unit. However, for the purposes of the present invention, some or all or the tertiary amine moieties can remain unmodified. These unmodified tertiary amine moieties by virtue of their position in the backbone chain remain "branching" units. The R units associated with the V, W and Y unit nitrogens which serve to connect the polyamine nitrogens, are described herein below. The final modified structure of the polyamines of the present invention can be therefore represented by the general formula

V(n+1)WmYnZ for linear amino-functional polymer and by the general formula V(n-k+1)WmYnY'kZ for cyclic amino-functional polymer. For the case of polyamines comprising rings, a Y' unit of the formula

I R

— [N-R]— serves as a branch point for a backbone or branch ring. For every Y' unit there is a Y unit having the formula

I

— ΓN-R]— that will form the connection point of the ring to the main polymer chain or branch. In the unique case where the backbone is a complete ring, the polyamine backbone has the formula

R' |

[ 2N-R]n-[N-R]m-[N-R]_n— therefore comprising no Z terminal unit and having the formula Vn-kWmYnY'k wherein k is the number of ring forming branching units. Preferably the polyamine backbones of the present invention comprise no rings.

In the case of non-cyclic polyamines, the ratio of the index n to the index m relates to the relative degree of branching. A fully non-branched linear modified polyamine according to the present invention has the formula V /VmZ that is, n is equal to 0. The greater the value of n (the lower the ratio of m to n), the greater the degree of branching in the molecule. Typically the value for m ranges from a minimum value of 2 to 700, preferably 4 to 400, however larger values of m, especially when the value of the index n is very low or nearly 0, are also preferred.

Each polyamine nitrogen whether primary, secondary or tertiary, once modified according to the present invention, is further defined as being a member of one of three general classes; simple substituted, quaternized or oxidized. Those polyamine nitrogen units not modified are classed into V, W, Y, Y' or Z units depending on whether they are primary, secondary or tertiary nitrogens. That is unmodified primary amine nitrogens are V or Z units, unmodified secondary amine nitrogens are W units or Y¹ units and unmodified tertiary amine nitrogens are Y units for the purposes of the present invention.

Modified primary amine moieties are defined as V "terminal" units having one of three forms: a) simple substituted units having the structure:

R^N-R —

I R' b) quaternized units having the structure:

R' X ^"

R'-N-R — I R' wherein X is a suitable counter ion providing charge balance; and c) oxidized units having the structure:

Modified secondary amine moieties are defined as W "backbone" units having one of three forms: a) simple substituted units having the structure:

-N I -R—

R' b) quaternized units having the structure:

wherein X is a suitable counter ion providing charge balance; and c) oxidized units having the structure:

Other modified secondary amine moieties are defined as Y' units having one of three forms: a) simple substituted units having the structure: -N-R-

R

b) quaternized units having the structure:

wherein X is a suitable counter ion providing charge balance; and c) oxidized units having the structure: O t

-N-R- I R

Modified tertiary amine moieties are defined as Y "branching" units having one of three forms: a) unmodified units having the structure:

— N-R—

I b) quaternized units having the structure:

wherein X is a suitable counter ion providing charge balance; and c) oxidized units having the structure:

Certain modified primary amine moieties are defined as Z "terminal" units having one of three forms: a) simple substituted units having the structure:

-N I -R'

R' b) quaternized units having the structure:

wherein X is a suitable counter ion providing charge balance; and c) oxidized units having the structure:

When any position on a nitrogen is unsubstituted of unmodified, it is understood that hydrogen will substitute for R'. For example, a primary amine unit comprising one R' unit in the form of a hydroxyethyl moiety is a V terminal unit having the formula (HOCH2CH2)HN-.

For the purposes of the present invention there are two types of chain terminating units, the V and Z units. The Z "terminal" unit derives from a terminal primary amino moiety of the structure -NH2. Non-cyclic polyamine backbones according to the present invention comprise only one Z unit whereas cyclic polyamines can comprise no Z units. The Z "terminal" unit can be substituted with any of the R' units described further herein below, except when the Z unit is modified to form an N-oxide. In the case where the Z unit nitrogen is oxidized to an N-oxide, the nitrogen must be modified and therefore R' cannot be a hydrogen.

The polyamines of the present invention comprise backbone R "linking" units that serve to connect the nitrogen atoms of the backbone. R units comprise units that for the purposes of the present invention are referred to as "hydrocarbyl R" units and "oxy R" units. The "hydrocarbyl" R units are C2-C12 alkylene, C4-C12 alkenylene, C3-C12 hydroxyalkylene wherein the hydroxyl moiety may take any position on the R unit chain except the carbon atoms directly connected to the polyamine backbone nitrogens; C4-C12 dihydroxyalkylene wherein the hydroxyl moieties may occupy any two of the carbon atoms of the R unit chain except those carbon atoms directly connected to the polyamine backbone nitrogens; C8-

C12 dialkylarylene which for the purpose of the present invention are arylene moieties having two alkyl substituent groups as part of the linking chain. For example, a dialkylarylene unit has the formula

although the unit need not be 1 ,4-substituted, but can also be 1 ,2 or 1 ,3 substituted C2-C12 alkylene, preferably ethylene, 1 ,2-propylene, and mixtures thereof, more preferably ethylene. The "oxy" R units comprise - (R1O)xR5(OR1)x-, -CH2CH(OR2)CH2O)z(R1O)yR1 (OCH2CH(OR2)CH2)w-, - CH2CH(OR2)CH2-, -(R1O)xR1-, and mixtures thereof. Preferred R units are selected from the group consisting of C2-C12 alkylene, C3-C12 hydroxyalkylene, C4-C12 dihydroxyalkylene, C8-C12 dialkylarylene, -(R1O)xR1-, CH2CH(OR2)CH2-, -(CH2CH(OH)CH2O)z(R1O)yR1(OCH2CH-(OH)CH2)w-, - (R1O)xR5(OR1)x-, more preferred R units are C2-C12 alkylene, C3-C12 hydroxy-alkylene, C4-C12 dihydroxyalkylene, -(R1O)xR1-, -(R1O)xR5(OR1)x-, - (CH2CH(OH)CH2O)z(R1O)yR1(OCH2CH-(OH)CH2)w-, and mixtures thereof, even more preferred R units are C2-C12 alkylene, C3 hydroxyalkylene, and mixtures thereof, most preferred are C2-C6 alkylene. The most preferred backbones of the present invention comprise at least 50% R units that are ethylene.

R1 units are C2-C6 alkylene, and mixtures thereof, preferably ethylene.

R2 is hydrogen, and -(R1O)xB, preferably hydrogen.

The preferred "oxy" R units are further defined in terms of the R1 , R2, and R5 units. Preferred "oxy" R units comprise the preferred R1 , R2, and R5 units. The preferred polyamines of the present invention comprise at least 50% R1 units that are ethylene. Preferred R1 , R2, and R5 units are combined with the "oxy" R units to yield the preferred "oxy" R units in the following manner.

i) Substituting more preferred R5 into -(CH2CH2O)xR5(OCH2CH2)x- yields -(CH2CH2O)xCH2CHOHCH2(OCH2CH2)x-. ii) Substituting preferred R1 and R2 into -(CH2CH(OR2)CH2O)z- (R1O)yR1O(CH2CH(OR2)CH2)w- yields -(CH2CH(OH)CH2O)z-

R' units are selected from the group consisting of hydrogen, C1-C22 alkyl, C3- C22 alkenyl, C7-C22 arylalkyl, C2-C22 hydroxyalkyl, -(CH2)pCO2M, - (CH2)qSO3M, -CH(CH2CO2M)CO2M, -(CH2)pPO3M, -(R1O)mB, -C(O)R3, preferably hydrogen, C2-C22 hydroxyalkylene, benzyl, C1-C22 alkylene, - (R1O)mB, -C(O)R3, -(CH2)pCO2M, -(CH2)qSO3M, -CH(CH2CO2M)CO2M, more preferably C1-C22 alkylene, -(R1O)xB, -C(O)R3, -(CH2)pCO2M, -(CH2)qSO3M, - CH(CH2CO2M)CO2M, most preferably C1-C22 alkylene, -(R1O)xB, and - C(O)R3. When no modification or substitution is made on a nitrogen then hydrogen atom will remain as the moiety representing R'. A most preferred R' unit is (R1O)xB.

R' units do not comprise hydrogen atom when the V, W or Z units are oxidized, that is the nitrogens are N-oxides. For example, the backbone chain or branching chains do not comprise units of the following structure:

.

Additionally, R' units do not comprise carbonyl moieties directly bonded to a nitrogen atom when the V, W or Z units are oxidized, that is, the nitrogens are N- oxides. According to the present invention, the R' unit -C(O)R3 moiety is not bonded to an N-oxide modified nitrogen, that is, there are no N-oxide amides having the structure or combinations thereof.

B is hydrogen, C1-C6 alkyl, -(CH2)qSO3M, -(CH2)pCO2M, -(CH2)q- (CHSO3M)CH2SO3M, -(CH2)q(CHSO2M)CH2SO3M, -(CH2)pPO3M, -PO3M, preferably hydrogen, -(CH2)qSO3M, -(CH2)q(CHSO3M)CH2SO3M, -(CH2)q- (CHSO2M)CH2SO3M, more preferably hydrogen or -(CH2)qSO3M. M is hydrogen or a water soluble cation in sufficient amount to satisfy charge balance. For example, a sodium cation equally satisfies -(CH2)pCO2M, and -(CH2)qSO3M, thereby resulting in -(CH2)pCO2Na, and -(CH2)qSO3Na moieties. More than one monovalent cation, (sodium, potassium, etc.) can be combined to satisfy the required chemical charge balance. However, more than one anionic group may be charge balanced by a divalent cation, or more than one mono-valent cation may be necessary to satisfy the charge requirements of a poly-anionic radical. For example, a -(CH2)pPO3M moiety substituted with sodium atoms has the formula -(CH2)pPO3Na3. Divalent cations such as calcium (Ca2+) or magnesium (Mg2+) may be substituted for or combined with other suitable mono-valent water soluble cations. Preferred cations are sodium and potassium, more preferred is sodium.

Preferably x has a value lying in the range of from 1 to 20, preferably from 1 to 10.

The preferred amino-functional polymers of the present invention comprise polyamine backbones wherein less than 50% of the R groups comprise "oxy" R units, preferably less than 20% , more preferably less than 5%, most preferably the R units comprise no "oxy" R units.

The most preferred amino-functional polymers which comprise no "oxy" R units comprise polyamine backbones wherein less than 50% of the R groups comprise more than 3 carbon atoms. For example, ethylene, 1 ,2-propylene, and 1 ,3- propylene comprise 3 or less carbon atoms and are the preferred "hydrocarbyl" R units. That is when backbone R units are C2-C12 alkylene, preferred is C2-C3 alkylene, most preferred is ethylene.

The amino-functional polymers of the present invention comprise modified homogeneous and non-homogeneous polyamine backbones, wherein 100% or less of the -NH units are modified. For the purpose of the present invention the term "homogeneous polyamine backbone" is defined as a polyamine backbone having R units that are the same (i.e., all ethylene). However, this sameness definition does not exclude polyamines that comprise other extraneous units comprising the polymer backbone which are present due to an artefact of the chosen method of chemical synthesis. For example, it is known to those skilled in the art that ethanolamine may be used as an "initiator" in the synthesis of polyethyleneimines, therefore a sample of polyethyleneimine that comprises one hydroxyethyl moiety resulting from the polymerization "initiator" would be considered to comprise a homogeneous polyamine backbone for the purposes of the present invention. A polyamine backbone comprising all ethylene R units wherein no branching Y units are present is a homogeneous backbone. A polyamine backbone comprising all ethylene R units is a homogeneous backbone regardless of the degree of branching or the number of cyclic branches present.

For the purposes of the present invention the term "non-homogeneous polymer backbone" refers to polyamine backbones that are a composite of various R unit lengths and R unit types. For example, a non-homogeneous backbone comprises R units that are a mixture of ethylene and 1 ,2-propylene units. For the purposes of the present invention a mixture of "hydrocarbyl" and "oxy" R units is not necessary to provide a non-homogeneous backbone. Preferred amino-functional polymers of the present invention comprise homogeneous polyamine backbones that are totally or partially substituted by polyethyleneoxy moieties, totally or partially quaternized amines, nitrogens totally or partially oxidized to N-oxides, and mixtures thereof. However, not all backbone amine nitrogens must be modified in the same manner, the choice of modification being left to the specific needs of the formulator. The degree of ethoxylation is also determined by the specific requirements of the formulator.

The preferred polyamines that comprise the backbone of the compounds of the present invention are generally polyalkyleneimines (PAI's), preferably polyethyleneimines (PEI's), or PEI's connected by moieties having longer R units than the parent PAI's or PEI's.

Preferred amine polymer backbones comprise R units that are C2 alkylene (ethylene) units, also known as polyethylenimines (PEI's). Preferred PEI's have at least moderate branching, that is the ratio of m to n is less than 4:1 , however PEI's having a ratio of m to n of 2:1 are most preferred. Preferred backbones, prior to modification have the general formula:

^R' I [R₂NCH₂CH₂]n-[NCH₂CH₂]_m-[NCH₂CH₂]n-NR₂

wherein R', m and n are the same as defined herein above. Preferred PEI's will have a molecular weight greater than 200 daltons.

The relative proportions of primary, secondary and tertiary amine units in the polyamine backbone, especially in the case of PEI's, will vary, depending on the manner of preparation. Each hydrogen atom attached to each nitrogen atom of the polyamine backbone chain represents a potential site for subsequent substitution, quaternization or oxidation.

These polyamines can be prepared, for example, by polymerizing ethyleneimine in the presence of a catalyst such as carbon dioxide, sodium bisulfite, sulfuric acid, hydrogen peroxide, hydrochloric acid, acetic acid, etc. Specific methods for preparing these polyamine backbones are disclosed in U.S. Patent 2,182,306, Ulrich et al., issued December 5, 1939; U.S. Patent 3,033,746, Mayle et al., issued May 8, 1962; U.S. Patent 2,208,095, Esselmann et al., issued July 16, 1940; U.S. Patent 2,806,839, Crowther, issued September 17, 1957; and U.S. Patent 2,553,696, Wilson, issued May 21 , 1951 ; all herein incorporated by reference.

3.6-Peptidic _.polymer

Most preferred compounds for use in the present invention are amino acids and their derivatives, especially ester and amide derivatives. These peptidic polymers are linked to the CBD via a peptidic linkage. More preferred compounds are those providing enhanced surface substantivity due to its structural feature. Suitable amino acids have the following functionality of formula:

NH₂ OLR*

R=H, (L)-R*,

Suitable amino acids for use herein are selected tyrosine, tryptophane, lysine, glutamic acid, glutamine, aspartic acid, arginine, asparagine, phenylalanine, proline, glycine, serine, histidine, threonine, methionine, and mixture thereof. Homopolymers with the same amino acids or heteropolymers with different amino acids are suitable. For example, the amino acids Serine, Threonine and Tyrosine possess the reactive hydroxyl group, the Cysteine present a reactive SH group, the Asparagine and Glutamine amino acids possess a reactive amido group and the Lysine a reactive amino group. The linking will preferably be achieved on the Tyrosine, Cysteine or Lysine. Especially, the free NH2 group from a Lysine amino acid or of the terminal amino acid within the peptidic polymer is used as attachment points for chemicals containing aldehyde, ene one, ketone, or acid or halogene moeities

Also suitable compound are the amino acid derivatives selected from tyrosine ethylate, glycine methylate, tryptophane ethylate and mixture thereof,

These peptidic polymers can be attached to the amino acid sequence comprising a cellulose binding domain, by recombinant technology. An example of the recombinant technique describing the expression of an enzyme with the CBD of different origin is described in S. Karita et al., (1996) Journal of Fermentation and Bioengineering, Vol. 81 , No. 6, pp. 553-556. The polyreactive linking region can comprise from 1 to about 100 amino acid residues, in particular of from 2 to 40 amino acid residues, e.g. from 2 to 15 amino acid residues. It is preferred to use amino acids which are less favoured by the surrounding proteases. Indeed, any combination of amino acids can be selected to achieve maximal weight efficiency and protease stability.

As stated above, some chemical components are linked to these cellulose binding domains, linking regions and/or polyreactive linking regions via a weak bond. Said weak bond is a bond which can be enzymatically cleaved, oxidised, cleaved by light radiation and/or hydrolysed during or after the wash/fabric care process in order to release the chemical component(s). Examples of weak bonds are Shiff-base or beta-amino-ketone linking.

The chemical components

The chemical component of the present invention may be encapsulated. Suitable encapsulating material includes starches, poly(vinylacetate), urea/formaldehyde condensate based materials. Especially suitable encapsulating materials are water soluble capsules which consist of a matrix of polysaccharide and polyhydroxy compounds such as described in GB 1 ,464,616. Other suitable water soluble encapsulating materials comprise dextrins derived from ungelatinized starch acid-esters of substituted dicarboxylic acids such as described in US 3,455,838. These acid-ester dextrins are, preferably, prepared from such starches as waxy maize, waxy sorghum, sago, tapioca and potato.

Suitable examples of said encapsulating materials include N-Lok manufactured by National Starch. The N-Lok encapsulating material consists of a modified maize starch and glucose. The starch is modified by adding monofunctional substituted groups such as octenyl succinic acid anhydride.

Perfumes Most consumers have come to expect scented laundry products and to expect that fabrics which have been laundered also have a pleasing fragrance. It is also desired by consumers for laundered fabrics to maintain the pleasing fragrance over time. Perfume additives make laundry compositions more aesthetically pleasing to the consumer, and in some cases the perfume imparts a pleasant fragrance to fabrics treated therewith. However, the amount of perfume carryover from an aqueous laundry bath onto fabrics is often marginal and does not last long on the fabric. Fragrance materials are often very costly and their inefficient use in rinse added fabric softener compositions and ineffective delivery to fabrics from the rinse results in a very high cost to both consumers and fabric softener manufacturers. Industry, therefore, continues to seek with urgency for more efficient and effective fragrance delivery in fabric softener products, especially for improvement in the provision of long-lasting fragrance to the rinsed fabrics. Therefore, industry continues to seek improved alternatives for generating fragrances through economic and effective means.

The present invention encompasses a perfume entity comprising more than one chemical components wherein at least one component is a perfume compound, linked to an amino acid sequence comprising a cellulose binding domain. The perfume compound is linked to the CBD, linking region and/or polyreactive linking region via a weak bond. It is believed that high substantivity of the perfume will be achieved by linking perfume compounds to a CBD. A complex of several perfumes with different perfumery notes can be formed. Also encompassed in the present invention are laundry detergent and/or fabric care compositions comprising one or more of these perfume entities.

Without wishing to be bound by theory, it is believed that the slow hydrolysis of the CBD-perfume direct or indirect linking will improve the release of the perfume. Indeed, after the wash or fabric care process, the weak bond will be hydrolysed and the perfume will be released. It has been surprisingly found that such perfume entities provide pleasing, long-lasting fragrance, through economic and effective means.

For example, it is known that alcohols represent key notes in perfumery. However, many alcohols are too volatile to remain in a perceptible way on dry fabrics and/or are not sufficiently fabric substantive to deposit on fabric in an optimum way such as in a softening through-the-wash process. The linking of these perfumery alcohols to the CBD, linking region and/or polyreactive linking region can be achieved for instance via an ester bond to a carboxylic group of the polyreactive linking region or to a molecule of succinic acid which is itself linked to an hydroxy group of the polyreactive linking region.

A further example are the perfumery aldehydes known to provide a fresh note on fabrics and especially on dry fabrics. However many perfumery aldehydes do not deposit substantially enough on the fabrics and/or are too volatile. A known solution to the art consists in using a second perfumery material containing an amine group to form a Shift base. Said Shift bases present a higher residuality on the fabrics but do not have fabric substantivity and cause a change in the aldehyde perfume character. Such perfume entities provide high fabric substantivity which results in the reduction of the perfume waste in the wash of fabric care drain and in increased perfume retention on the fabrics, i.e., increased through the wash deposition. Moreover, these perfume entities provide significant release of the perfume on laundered dry fabrics. Furthermore, the amine groups encompassed within the CBD, linking region and/or polyreactive linking region of the present invention do not have any odour impact nor change the perfume character.

Generally, these perfume entities will be comprised at a level of 0% to 10%, preferably 0% to 3%, more preferably 0% to 1% by weight of the total composition.

Fully-formulated fragrance can be prepared using numerous known odorant ingredients of natural or synthetic origin. The range of the natural raw substances can embrace not only readily-volatile, but also moderately-volatile and slightly-volatile components and that of the synthetics can include representatives from practically all classes of fragrant substances, as will be evident from the following illustrative compilation. In this list of perfume ingredients, some are commercial names conventionally known to one skilled in the art, and also includes isomers. Such isomers are also suitable for use in the present invention. A typical disclosure of suitable ketone and/or aldehydes, traditionally used in perfumery, can be found in "perfume and Flavor Chemicals", Vol. I and II, S. Arctander, Allured Publishing, 1994, ISBN 0-931710-35-5. Preferred for the purpose of the present invention are the aldehydes or ketones based products.

Hygiene agent

Sanitisation includes all positive effects obtained by the inhibition or reduction of microbial activity on fabrics and other surfaces, such as the prevention of malodour development and bacterial/fungal growth. For example, it provides prevention of malodour development on stored and weared fabrics. In particular, the composition of the invention will inhibit or at least reduce the bacterial and/or fungal development on moist fabric waiting for further laundry processing and thereby preventing the formation of malodour. The term hygiene agents herein encompasses fungicides and antimicrobials that when applied to fabric respectively prevent or reduce the growth of fungi or bacteria. The sanitisation benefits of the laundry detergent and/or fabric care compositions of the present invention can be evaluated by the Minimum Inhibitory Concentration (MIC) as described in Tuber. Lung. Dis. 1994 Aug; 75(4):286-90; J. Clin. Microbiol. 1994 May; 32(5):1261-7 and J. Clin. Microbiol. 1992 Oct; 30(10):2692-7.

This hygiene agent entity comprises more than one chemical components wherein at least one component is a hygiene agent, linked to an amino acid sequence comprising a Cellulose Binding Domain. The hygiene agent will be linked to the CBD, linking region and/or polyreactive linking region via weak bond in order to release the active material upon time during or after the wash or fabric care process. Such hygiene agent entity can be incorporated in a laundry detergent and/or fabric care composition of the present invention. Preferably, the hygiene agent comprises an hydroxyl, carboxyl or aldehyde reactive moiety. It has been surprisingly found that such hygiene agent entities provide long lasting and efficient control of the micro-organism growth on stored and weared fabrics.

Insect Control agent

The present invention encompasses insect control agent entities. This insect control agent entity comprises more than one chemical components wherein at least one component is an insect control agent, linked to an amino acid sequence comprising a Cellulose Binding Domain. Laundry detergent and/or fabric care compositions of the present invention can comprise such insect control agent entity. It has been surprisingly found that such insect control agent entities provide long lasting insect control by the slow release of the insect control agent.

Such insect control agents are linked to the CBD, linking region and/or polyreactive linking region preferably via a weak bond in order to release upon time the active material. For example, these materials can be linked to the NH2 group present in the CBD, linking region and/or polyamino polymer via a Shift base or Michael reaction.

The term insect control agent refers to both insecticides and insect repellents either individually or as mixtures. Examples of insect repellents can be found in Kirk-Othmer Encyclopedia of Chemical technology, Fourth edition, volume 13, pages 474 to 478. Suitable insect repellents include aldehyde based compounds such as Citronellal and Rotundial, ene one based compounds such as Butopyronoxyl (Indalone TM), benzyl benzoate, bioallethrin and dimethrin, N,N- diethyl toluamide ("DEET"), N,N-diethyl benzamide, p-menthane-3,8-diol, 1S,3S,4S,6S-carene-3,4diol (Sumitomo - US5,130,136), 1-piperidinecarboxylic acid, 2-(2-hydroxyethyl)-, 1-methylpropylester, 1-(3cyclohexen-1-yl carbonyl)- 2methylpiperidine, 1-(3-cyclohexen-1-yl carbonmyl) piperidine, N,N-diethyl mandelamide, isopulegol hydrate, ethyl-3(N-butyl-N-acetyl) aminopropionate, diisopropyladipate, α-biasal, psearmint oil, benzyl alcohol, N,N- diethylphenylacetamide, vitamin E, citronella oil, coconut oil, cedar oil, geraniol, lemon grass oil, thyme oil, reosemary oil, mint oil, geranium oil, eugenol, 3- acetyl-2-(2-,6-dimethyl-5-heptenyl) oxazolidine, (2- hydroxymethylcyclohexyl)acetic acid lactone and eucalyptol. Other insect control agents are based on pyrethroid insecticides, in particular 3-phenoxybenzyl-DL- cis, trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane-carboxylate

(permethrin). WO98/17772 describes the insect repellent agent 3-(N- butylacetamino) ethyl propionate for use in detergents. Preferred insect repellents are aldehyde based compounds such as Citronellal and Rotundial.

These insect control agent entities are generally comprised in the laundry detergent and/or fabric care compositions of the present invention at a level of from 0.1% to 20%, preferably 0.1% to 10%, more preferably 0.1% to 6% by weight of the composition.

Bleaching agent

The present invention encompasses a bleaching entity comprising more than one chemical components wherein at least one component is a bleaching agent, linked to an amino acid sequence comprising a cellulose binding domain. Said bleaching agent can be selected from hydrophilic bleach activator, hydrophobic bleach activator, metal catalyst and/or photoactivated bleach. It has been surprisingly found that the bleaching action with such bleaching entities results in improved stain/soil bleaching/removal and whiteness maintenance. Also encompassed in the present invention, are laundry detergent and/or fabric care compositions comprising such a bleaching entity.

Without wishing to be bound by theory, it is believed that improved stain/soil bleaching/removal and whiteness maintenance results in the generation of oxygen radical, peracetic acid or peracid perhydrolysis occurring very close the fabric. Said peracetic acid or peracid is less dilute in the wash solution and thereby improve the bleaching action on the fabric.

Preferably, the bleach activator is linked to the CBD via a linking region, more preferably via a polyreactive linking region. Without wishing to be bound by theory, it is believed that the presence of such linking region and/or polyreactive linking region provides some flexibility to the bleach activator that can move around the CBD and perform more efficiently on the fabric its bleaching action.

1) Hydrophilic bleach activator : For example, Tetra Acetyl Ethylene Diamine (TAED) is a current bleach activator used in laundry detergent and forms peracetic acid in presence of H2O2. It is known that the two NH2 groups of the Ethylene Diamine are diacetylated to form TAED. Without wishing to be bound by theory, it is believed that the diacetylation of the free NH2 groups of the CBD, linking region or polyreactive linking region, forms a substantive fabric hydrophilic bleach activator. Hydrophilic bleach activator of the TAED type can be linked for example via a diacetylation reaction to any NH2 groups of the CBD, linking region and/or polyreactive linking region of the present invention.

2) Hydrophobic bleach activators such as Nonanoyl benzene sulphonate, are current bleach activators used in laundry detergent. It has been surprisingly found that the phenolic moiety can be replaced by the one present in the tyrosine amino acid present in the CBD, linking region and/or polyreactive linking region. Active hydrophobic bleach activator precursors such as nonanyl unit can be linked to the phenol group of an amino acid such as tyrosine present in the peptidic CBD, linking region and/or polyreactive linking region. Similarly, if there is no phenol entity available in the CBD, linking region and/or polyreactive linking region, a phenol unit can be linked to a group NH2 in this CBD, linking region and/or polyreactive linking region. Hydrophobic bleach activators in general can be linked to the CBD, linking region and/or polyreactive linking region for example by a reaction on NH2 groups.

Other examples of suitable hydrophobic bleach activators are nonanoyloxybenzene-sulfonate (NOBS, described in US 4,412,934), 3,5,- trimethylhexanoloxybenzenesulfonate (ISONOBS, described in EP 120,591) or pentaacetylglucose (PAG) or Phenolsulfonate ester of N-nonanoyl-6- aminocaproic acid (NACA-OBS, described in WO94/28106), which are perhydrolyzed to form a peracid as the active bleaching species, leading to improved bleaching effect. Also suitable bleach activators are the activators based on a caprolactam leaving group such as benzoyl caprolactam and quaternary ammonium hexanoyl caprolactam; the imides activators such as N-nonanoyl-N-methyl acetamide and unsymetrical acyclic imide bleach activator of the following formula as disclosed in the Procter & Gamble co-pending patent applications US serial No. 60/022,786 (filed July 30, 1996) and No. 60/028,122 (filed October 15, 1996) :

wherein Ri is a C7-C13 linear or branched chain saturated or unsaturated alkyl group, R2 is a Cι-Cs_] linear or branched chain saturated or unsaturated alkyl group and R3 is a C-1-C4 linear or branched chain saturated or unsaturated alkyl group.. These bleach activators can for example be linked to any NH2 groups of the polyreative linking region.

Also suitable are the pre-fromed peracid such as nonylamido peroxy adipic acid and N,N-phtaloylaminoperoxy caproic acid and the Di-acyl peroxides such as dobenzoyl peroxide.

3) Metal catalysts : The third type of bleach activator that can be linked to one or more CBD(s) are the below described metal catalysts. For example, these catalysts can be linked via their capping cyclo azo moieties to NH2 groups of the CBD, linking region and/or polyreactive linking region. Examples of Metal-containing catalysts for use in bleach compositions, include cobalt-containing catalysts such as Pentaamine acetate cobalt(lll) salts and manganese-containing catalysts such as those described in EPA 549 271 ; EPA 549 272; EPA 458 397; US 5,246,621 ; EPA 458 398; US 5,194,416 and US 5,114,611. Bleaching composition comprising a peroxy compound, a manganese-containing bleach catalyst and a chelating agent is described in the patent application No 94870206.3.

4) Photoactivated bleach : Another group of suitable bleach activators that can be linked the CBD, linking region and/or polyreactive linking region of the present invention are the photoactivated bleaches. For example, the linking can be achieved between the NH2 groups of and the benzyls groups of these photoactivated bleaches, activated via a preliminary bromination. Suitable photoactivated bleaching agents are the sulfonated zinc and/or aluminum phthalocyanines. These materials can be deposited upon the substrate during the washing process. Upon irradiation with light, in the presence of oxygen, such as by hanging clothes out to dry in the daylight, the sulfonated zinc phthalocyanine is activated and, consequently, the substrate is bleached. Preferred zinc phthalocyanine and a photoactivated bleaching process are described in U.S. Patent 4,033,718. Typically, detergent compositions will contain about 0.025% to about 1.25%, by weight, of sulfonated zinc phthalocyanine.

Generally, these bleaching entity will be comprised at a level of 0% to 20%, preferably 0% to 10%, more preferably 0% to 5% by weight of the total composition.

In addition to this bleaching entity the compositions of the present invention can further comprise bleaching species such as hydrogen peroxide, PB1 , PB4 and percarbonate with a particle size of 400-800 microns, typically be present at levels of from about 1% to about 25%.

Fabric Softening Composition Ingredients

The present invention encompasses a fabric softening entity. This fabric softening entity comprises more than one chemical components wherein at least one component is a softening component, linked to an amino acid sequence comprising a cellulose binding domain. These fabric softening entities can be incorporated in a laundry detergent and/or fabric care composition. It has been surprisingly found that such fabric softening entities provide, refurbish or restore tensile strength, anti-wrinkle, anti-bobbling and anti-shrinkage properties to fabrics, as well as provide static control, fabric softness, colour appearance and fabric anti-wear properties and benefits.

Indeed in recent years, consumer desirability for durable press fabric garments, particularly cotton fabric garments, has risen. Durable press garments include those garments which resist wrinkling of the fabric both during wear and during the laundering process. Durable press garments can greatly decrease the hand work associated with laundering by eliminating ironing sometimes necessary to prevent wrinkling of the garment. However, in most commercially available durable press fabrics, the fabric's ability to resist wrinkling is reduced over time as the garment is repeatedly worn and laundered.

Generally, these fabric softening entities will be comprised at a level of 0% to 50%, preferably 0% to 30, more preferably 0% to 15% by weight of the total composition.

One suitable softening component are dialkyl units that can be linked for example, by dialkylation of the NH2 groups comprised in the CBD, linking region an/or polyreactive linking region. Preferably such fabric softening entities will not comprise a weak bond.

Dialkyl units suitable for the compositions of the present invention can be extracted from the following cationic softening surfactants currently used in the laundry detergent and/or fabric care context.

The alkyl, or alkenyl chain must contain at least 11 carbon atoms, preferably at least 16 carbon atoms. The chain may be straight or branched. Specific examples of the alkyl or alkenyl chains herein include : 1) N,N-di(tallowyl-oxy-ethyl); 2) N,N-di(2-tallowyloxy-2-oxo-ethyl);

3) N,N-di(2-tallowyloxyethylcarbonyloxyethyl); 4)N-(2-tallowoyloxy-2-ethyl)-N-(2-tallowyloxy-2-oxo-ethyl);

5) N-(2-tallowyloxy-2-oxoethyl)-N-(tallowyl); and

6) 1 ,2-ditallowyloxy; and mixtures of any of the above materials. Preferred alkyl chains for the purpose of the present invention N,N-di(tallowoyl- oxy-ethyl), where the tallow chains are at least partially unsaturated.

Other suitable softening components include quaternary ammonium softening compounds having a solubility in water at pH2.5 and 20°C of less than 10g/l. It is particularly advantageous if the softening component is a quaternary ammonium compound in which at least one long chain alkyl group is connected to the quaternary ammonium compound via at least one ester link. Suitable cationic softener are described in US4,137,180 (Naik) and WO93/23510.

Also suitable as softening components are clay or silicone. Suitable clays include a three layered smectite clay, preferably having a cationic exchange capacity as described in GB 1 ,400,898 and in USP 5,019,292. Especially preferred are clays which are 2:1 layer phyllosilicates possessing a lattice charge efficiency in the range of 0.2 to 0.4g equivalent per half unit cell as described in EP 350 288 (Unilever).

Also encompassed in the present invention are any polymeric lubricant suitable for softening a fabric. These include silicone and in particular those described in GB1 , 549,180, EP 459 821 (Unilever) and EP 459 822 (Unilever).

Dye fixative agents

The present invention encompasses a dye fixative entity. This dye fixative entity comprises more than one chemical components wherein at least one component is a dye fixative agent, linked to an amino acid sequence comprising a cellulose binding domain. Also encompassed in the present invention are laundry detergent and/or fabric care compositions comprising a dye fixative entity. It has been surprisingly found that such dye fixative entities provide improved anti-wear properties, colour appearance.

Indeed, coloured garments have a tendency to wear and show appearance losses. A portion of this colour appearance loss may be attributed to abrasion in the laundering process, particularly in automatic washing machines and automatic laundry dryers. Dye fixing agents, or "fixatives", are well-known, commercially available materials which are designed to improve the appearance of dyed fabric by minimising the loss of dye from fabrics due to washing. Many dye fixatives are cationic, and are based on various quaternized or otherwise cationically charged organic nitrogen compounds. Fixatives are available under various trade names from several suppliers. Representative examples include: CROSCOLOR PMF (July 1981 , Code No. 7894) and CROSCOLOR NOFF (January 1988, Code No. 8544) from Crosfield; INDOSOL E-50 (February 27, 1984, Ref. No. 6008.35.84; poϊyethyleneamine-based) from Sandoz; SANDOFIX TPS, which is also available from Sandoz and is a preferred polycationic fixative for use herein and SANDOFIX SWE (cationic resinous compound), REWIN SRF, REWIN SRF-O and REWIN DWR from CHT-Beitlich GMBH.

Other cationic dye fixing agents are described in "Aftertreatments for improving the fastness of dyes on textile fibres" by Christopher C. Cook (REV. PROG. COLORATION Vol. 12, 1982). Dye fixing agents suitable for use in the present invention are ammonium compounds such as fatty acid - diamine condensates e.g. the hydrochloride, acetate, metosulphate and benzyl hydrochloride of oleyldiethyl aminoethylamide, oleylmethyl-diethylenediaminemethsulphate, monostearyl-ethylene diaminotrimethylammonium methosulphate and oxidised products of tertiary amines; derivatives of polymeric alkyldiamines, polyamine- cyanuric chloride condensates and aminated glycerol dichlorohydrins.

The amount of dye fixing entities to be employed in the composition of the invention is preferably from about 0.01% to about 15% by weight of the composition, more preferably from about 0.1% to about 15% by weight, most preferably from about 0.25% to about 10% by weight of the composition.

Soil release polymers

The present invention encompasses a soil release entity. This soil release entity comprises more than one chemical components wherein at least component is a soil release material, linked to an amino acid sequence comprising a cellulose binding domain. It has been surprisingly found that such modified soil release material provide better deposition of the soil release agent onto the fabric and therefore better soil release performance. Also encompassed in the present invention are laundry detergent and/or fabric care compositions comprising a soil release entity.

The soil release material suitable in the present invention are ethylene glycols oligomers, polyethylene glycol and derivatives such as transesterified polyethylene glycols, and propylene polyoxy ethylene. Other suitable soil release agents useful in compositions of the present invention are conventionally copolymers or terpolymers of terephthalic acid with ethylene glycol and/or propylene glycol units in various arrangements. Examples of such polymers are disclosed in the commonly assigned US Patent Nos. 4116885 and 4711730 and European Published Patent Application No. 0 272 033. A particular preferred polymer in accordance with EP-A-0 272 033 has the formula

(CH₃(PEG)43)o.75(POH)o.25[T-PO)2.8(T-PEG)o.4]T(PO-

H)o.25((PEG)43CH₃)o.75 where PEG is -(OC2H4)O-,PO is (OC3H6O) and T is (PCOC6H4CO).

Also very useful are modified polyesters as random copolymers of dimethyl terephthalate, dimethyl sulfoisophthalate, ethylene glycol and 1-2 propane diol, the end groups consisting primarily of sulphobenzoate and secondarily of mono esters of ethylene glycol and/or propane-diol. The target is to obtain a polymer capped at both end by sulphobenzoate groups, "primarily", in the present context most of said copolymers herein will be end-capped by sulphobenzoate groups. However, some copolymers will be less than fully capped, and therefore their end groups may consist of monoester of ethylene glycol and/or propane 1-2 diol, thereof consist "secondarily" of such species.

The selected polyesters herein contain about 46% by weight of dimethyl terephthalic acid, about 16% by weight of propane -1.2 diol, about 10% by weight ethylene glycol about 13% by weight of dimethyl sulfobenzoic acid and about 15% by weight of sulfoisophthalic acid, and have a molecular weight of about 3.000. The polyesters and their method of preparation are described in detail in EPA 311 342.

Other soil release agents currently used in the detergent context are those of

U.S. 4,968,451 , November 6, 1990 to J.J. Scheibel and E.P. Gosselink: such ester oligomers can be prepared by (a) ethoxylating allyl alcohol, (b) reacting the product of (a) with dimethyl terephthalate ("DMT") and 1 ,2-propylene glycol ("PG") in a two-stage transesterification/oligomerization procedure and (c) reacting the product of (b) with sodium metabisulfite in water; the nonionic end- capped 1 ,2-propylene/polyoxyethylene terephthalate polyesters of U.S. 4,711,730, December 8, 1987 to Gosselink et al, for example those produced by transesterification/oligomerization of poly(ethyleneglycol) methyl ether, DMT, PG and poly(ethyleneglycol) ("PEG"); the partly- and fully- anionic-end-capped oligomeric esters of U.S. 4,721 ,580, January 26, 1988 to Gosselink, such as oligomers from ethylene glycol ("EG"), PG, DMT and Na-3,6-dioxa-8- hydroxyoctanesulfonate; the nonionic-capped block polyester oligomeric compounds of U.S. 4,702,857, October 27, 1987 to Gosselink, for example produced from DMT, Me-capped PEG and EG and/or PG, or a combination of DMT, EG and/or PG, Me-capped PEG and Na-dimethyl-5-sulfoisophthalate; and the anionic, especially sulfoaroyl, end-capped terephthalate esters of U.S. 4,877,896, October 31 , 1989 to Maldonado, Gosselink et al, the latter being typical of SRA's useful in both laundry and fabric conditioning products, an example being an ester composition made from m-sulfobenzoic acid monosodium salt, PG and DMT optionally but preferably further comprising added PEG, e.g., PEG 3400. Another preferred soil release agent is a sulfonated end-capped type described in US 5,415,807.

Brighteners

The present invention encompasses a brightener entity. This brightener entity comprises more than one chemical components wherein at least one component is a brightener, linked to an amino acid sequence comprising a cellulose binding domain. It has been surprisingly found that such brightener entity provides better deposition of the brightener onto the fabric and therefore better whiteness maintenance performance. In addition, it has been found that various brighteners not currently used in the detergent field could also be used in the present invention thanks to their increased fabric substantivity, in particular during a softening-through-the-wash process. Preferably, such brightener entities will not comprise a weak bond. Also encompassed are laundry detergent and/or fabric care compositionscomprising a brightener entity. When therein included, the compositions herein may contain from about 0.005% to 5% by weight of certain types of hydrophilic optical brighteners which also provide a dye transfer inhibition action. If used, the compositions herein will preferably comprise from about 0.001% to 3.5% by weight of such optical brighteners.

Suitable brighteners for compositions of the present invention are :

- Carbocycles types of compounds such as distyrylbenzenes, distyrylbiphenyls and divinylstibenes, - Triazinylaminostilbenes,

- Stilbenyl-2H-triazoles such as stilbenyl-2H-naphtol[1 ,2-d]triazoles and bis(1 ,2,3-triazol-2-yl)stilbenes,

- Benzoxazoles such as stilbenylbenzoxazoles and bis(benzoxazoles),

Conventional detergent enzymes

The present invention encompasses an enzyme entity. This enzyme entity comprises more than one chemical components wherein at least one component is an enzyme which provide cleaning performance, fabric care and/or sanitisation benefits, linked to an amino acid sequence comprising a cellulose binding domain. Also encompassed are laundry detergent and/or fabric care compositions comprising an enzyme entity.

Without wishing to be bound by theory, It has been surprisingly found that said enzymes entitiy more readily attaches, affixes or otherwise comes into closer and/or more lasting contact with the fabric, thereby resulting in increased or enhanced performance of the enzyme. In particular, the laundry detergent and/or fabric care compositions of the present invention when comprising said enzyme entities, provide improved enzymatic benefits, i.e. improved enzymatic stain removal, enhanced enzymatic fabric care and/or improved enzymatic sanitisation benefits. Said enhanced enzymatic benefits are achieved by means of a process wherein the fabric is contacted with an enzyme entitiy which has increased affinity (relative to unmodified enzyme) for binding to a cellulosic fabric or textile.

Said enzymes include enzymes selected from cellulases, hemicellulases, peroxidases, proteases, gluco-amylases, amylases, xylanases, lipases, phospholipases, esterases, cutinases, pectinases, keratanases, reductases, oxidases, phenoloxidases, lipoxygenases, ligninases, pullulanases, tannases, pentosanases, malanases, β-glucanases, arabinosidases, hyaluronidase, chondroitinase, laccase or mixtures thereof.

Said cellulases are normally incorporated in the detergent composition at levels from 0.0001% to 2% of pure enzyme by weight of the detergent composition.

Peroxidase enzymes are used in combination with oxygen sources, e.g. percarbonate, perborate, persulfate, hydrogen peroxide, etc and with a phenolic substrate as bleach enhancing molecule. They are used for "solution bleaching", i.e. to prevent transfer of dyes or pigments removed from substrates during wash operations to other substrates in the wash solution. Peroxidase enzymes are known in the art, and include, for example, horseradish peroxidase, ligninase and haloperoxidase such as chloro- and bromo-peroxidase. Peroxidase-containing detergent compositions are disclosed, for example, in PCT International Application WO 89/099813, WO89/09813 and in European Patent application EP No. 91202882.6, filed on November 6, 1991 and EP No. 96870013.8, filed February 20, 1996.

Other amylases known for use in cleaning compositions include both α- and β-amylases. α- Amylases are known in the art and include those disclosed in US Pat. no. 5,003,257; EP 252,666; WO/91/00353; FR 2,676,456; EP 285,123; EP 525,610; EP 368,341 ; and British Patent specification no. 1 ,296,839 (Novo). Other suitable amylases are stability-enhanced amylases described in WO94/18314, published August 18, 1994 and WO96/05295, Genencor, published February 22, 1996 and amylase variants having additional modification in the immediate parent available from Novo Nordisk A/S, disclosed in WO 95/10603, published April 95.

The above-mentioned enzymes may be of any suitable origin, such as vegetable, animal, bacterial, fungal and yeast origin. Origin can further be mesophilic or extremophilic (psychrophilic, psychrotrophic, thermophilic, barophilic, alkalophilic, acidophilic, halophilic, etc.). Purified or non-purified forms of these enzymes may be used. Nowadays, it is common practice to modify wild-type enzymes via protein / genetic engineering techniques in order to optimise their performance efficiency in the laundry detergent and/or fabric care compositions of the invention. For example, the variants may be designed such that the compatibility of the enzyme to commonly encountered ingredients of such compositions is increased. Alternatively, the variant may be designed such that the optimal pH, bleach or chelant stability, catalytic activity and the like, of the enzyme variant is tailored to suit the particular cleaning application.

In particular, attention should be focused on amino acids sensitive to oxidation in the case of bleach stability and on surface charges for the surfactant compatibility. The isoelectric point of such enzymes may be modified by the substitution of some charged amino acids, e.g. an increase in isoelectric point may help to improve compatibility with anionic surfactants. The stability of the enzymes may be further enhanced by the creation of e.g. additional salt bridges and enforcing calcium binding sites to increase chelant stability.

Said enzymes are normally incorporated in the detergent composition at levels from 0.0001% to 2% of pure enzyme by weight of the detergent composition. The enzymes can be added as separate single ingredients (prills, granulates, stabilized liquids, etc. containing one enzyme ) or as mixtures of two or more enzymes (e.g., cogranulates ). Other suitable chemical components

Other chemical components to be linked to a cellulose binding domain in accordance with the present invention are latex and resins. Latex are defined as a material suitable for improving the drape of fabric. Suitable materials include a polyvinylacetate homopolymer such as 9802 (Vinamul). Resins prevent the formation of pills on the fabrics. Suitable resins are Knittex BE from Ciba-Geigy or silicas such as Crosanol NS from Crosfiled.

The Cellulose Binding Domain (CBD)

In the present context, the terms "Cellulose Binding Domain or CBD" are intended to indicate an amino acid sequence capable of effecting binding of the cellulase to a cellulosic substrate (e.g. as described in P. Kraulis et al., Determination of the three-dimensional structure of the C terminal domain of cellobiohydrolase I from Trichoderma reesei. A study using nuclear magnetic resonance and hybrid distance geometry-dynamically simulated annealing. Biochemistry 28:7241-7257, 1989). The classification and properties of cellulose binding domains are presented in P. Tomme et al., in the symposium "Enzymatic degradation of insoluble polysaccharides" (ACS Symposium Series 618, edited by J.N. Saddler and M.H. Penner, ACS, 1995).

Cellulose-binding (and other carbohydrate-binding) domains are polypeptide amino acid sequences which occur as integral parts of large polypeptides or proteins consisting of two or more polypeptide amino acid sequence regions, especially in hydrolytic enzymes (hydrolases) which typically comprise a catalytic domain containing the active site for substrate hydrolysis and a carbohydrate- binding domain for binding to the carbohydrate substrate in question. Such enzymes can comprise more than one catalytic domain and one, two or three carbohydrate-binding domains, and they may further comprise one or more polypeptide amino acid sequence regions linking the carbohydrate-binding domain(s) with the catalytic domain(s), a region of the latter type usually being denoted a "linker". Examples of hydrolytic enzymes comprising a cellulose-binding domain are cellulase, xylanases, mannanases, arabinofuranosidases, acetylesterases and chitinases. "Cellulose-binding domains" have also been found in algae, e.g. in the red alga porphyra purpurea in the form of a non-hydrolytic polysaccharide- binding protein [see P. Tomme et al., Cellulose-binding domains - Classification and Properties in Enzymatic Degradation of Insoluble Carbohydrates , John N. Saddler and Michael H. Penner (Eds.), ACS Symposium Series, No. 618 (1996)]. However, most of the known CBDs (which are classified and referred to by P. Tomme et al. (op. cit.) as "cellulose-binding domains") derive from cellulases and xylanases.

In the present context, the term "cellulose-binding domain" is intended to be understood in the same manner as in the latter reference (P. Tomme et al., op. cit. ) The P. Tomme et al. reference classifies more than 120 "cellulose-binding domains" into 10 families (l-X) which may have different functions or roles in connection with the mechanism of substrate binding. However, it is to be anticipated that new family representatives and additional families will appear in the future.

In proteins/polypeptides in which CBDs occur (e.g. enzymes, typically hydrolytic enzymes such as cellulases), a CBD may be located at the N or C terminus or at an internal position. The part of a polypeptide or protein (e.g. hydrolytic enzyme) which constitutes a CBD per se typically consists of more than about 30 and less than about 250 amino acid residues. For example, those CBDs listed and classified in Family I in accordance with P. Tomme et al. (op. cit.) consist of 33- 37 amino acid residues, those listed and classified in Family I la consist of 95-108 amino acid residues, those listed and classified in Family VI consist of 85-92 amino acid residues, whilst one CBD (derived from a cellulase from Clostridium thermocellum) listed and classified in Family VII consists of 240 amino acid residues. Accordingly, the molecular weight of an amino acid sequence constituting a CBD per se will typically be in the range of from about 4kD to about 40kD, and usually below about 35kD.

Cellulose binding domains can be produced by recombinant techniques as described in H. Stalbrand et al., Applied and Environmental Microbiology, Mar. 1995, pp. 1090-1097; E. Brun et al., (1995) Eur. J. Biochem. 231, pp. 142-148; J.B. Coutinho et al., (1992) Molecular Microbiology 6(9), pp. 1243-1252

In order to isolate a cellulose binding domain of, e.g. a cellulase, several genetic engineering approaches may be used. One method uses restriction enzyme to remove a portion of the gene and then to fuse the remaining gene-vector fragment in frame to obtain a mutated gene that encodes a protein truncated for a particular gene fragment. Another method involves the use of exonucleases such as Ba131 to systematically delete nucleotides either externally from the 5' and the 3' ends of the DNA or internally from a restricted gap within the gene. These gene-deletion methods result in a mutated gene encoding a shortened gene molecule whose expression product may then be evaluated for substrate- binding (e.g. cellulose-binding) ability. Appropriate substrates for evaluating the binding ability include cellulosic materials such as Avicel ™ and cotton fibres. Other methods include the use of a selective or specific protease capable of cleaving a CBD, e.g., a terminal CBD, from the remainder of the polypeptide chain of the protein in question.

Preferred CBDs for the purpose of the present invention are selected from the group consisting of : CBDs CBHII from Trichoderma reesei, CBD CBHI from Trichoderma reesei and/or CBD family 45 from Humicola insolens. More preferred CBD for the purpose of the present invention is the CBD originating from the fungal Humicola Insolens cellulase sold under the tradename "Carezyme" by Novo Nordisk A/S.

More preferred levels of incorporation are 1 % to 35% by weight, most preferably from 1% to 30% by weight of laundry detergent and/or fabric care compositions in accord with the invention.

The surfactant is preferably formulated to be compatible with enzyme components present in the composition. In liquid or gel compositions the surfactant is most preferably formulated such that it promotes, or at least does not degrade, the stability of any enzyme in these compositions.

Preferred surfactant systems to be used according to the present invention comprise as a surfactant one or more of the nonionic and/or anionic surfactants described herein.

Polyethylene, polypropylene, and polybutylene oxide condensates of alkyl phenols are suitable for use as the nonionic surfactant of the surfactant systems of the present invention, with the polyethylene oxide condensates being preferred. These compounds include the condensation products of alkyl phenols having an alkyl group containing from about 6 to about 14 carbon atoms, preferably from about 8 to about 14 carbon atoms, in either a straight-chain or branched-chain configuration with the alkylene oxide. In a preferred embodiment, the ethylene oxide is present in an amount equal to from about 2 to about 25 moles, more preferably from about 3 to about 15 moles, of ethylene oxide per mole of alkyl phenol. Commercially available nonionic surfactants of this type include Igepal™ CO-630, marketed by the GAF Corporation; and Triton™ X- 45, X-114, X-100 and X-102, all marketed by the Rohm & Haas Company. These surfactants are commonly referred to as alkylphenol alkoxylates (e.g., alkyl phenol ethoxylates).

The condensation products of primary and secondary aliphatic alcohols with from about 1 to about 25 moles of ethylene oxide are suitable for use as the nonionic surfactant of the nonionic surfactant systems of the present invention. The alkyl chain of the aliphatic alcohol can either be straight or branched, primary or secondary, and generally contains from about 8 to about 22 carbon atoms. Preferred are the condensation products of alcohols having an alkyl group containing from about 8 to about 20 carbon atoms, more preferably from about 10 to about 18 carbon atoms, with from about 2 to about 10 moles of ethylene oxide per mole of alcohol. About 2 to about 7 moles of ethylene oxide and most preferably from 2 to 5 moles of ethylene oxide per mole of alcohol are present in said condensation products. Examples of commercially available nonionic surfactants of this type include Tergitol™ 15-S-9 (the condensation product of ^c11-C-15 linear alcohol with 9 moles ethylene oxide), Tergitol™ 24-L-6 NMW (the condensation product of C12- 14 primary alcohol with 6 moles ethylene oxide with a narrow molecular weight distribution), both marketed by Union Carbide Corporation; Neodoϊ™ 45-9 (the condensation product of C-14-C15 linear alcohol with 9 moles of ethylene oxide), Neodol™ 23-3 (the condensation product of C12-C13 linear alcohol with 3.0 moles of ethylene oxide), Neodol™ 45-7 (the condensation product of C14-C15 linear alcohol with 7 moles of ethylene oxide), Neodol™ 45-5 (the condensation product of C14-C15 linear alcohol with 5 moles of ethylene oxide) marketed by Shell Chemical Company, Kyro™ EOB (the condensation product of C13-C15 alcohol with 9 moles ethylene oxide), marketed by The Procter & Gamble Company, and Genapol LA O3O or O5O (the condensation product of C12-C14 alcohol with 3 or 5 moles of ethylene oxide) marketed by Hoechst. Preferred range of HLB in these products is from 8-11 and most preferred from 8-10.

Also useful as the nonionic surfactant of the surfactant systems of the present invention are the alkylpolysaccharides disclosed in U.S. Patent 4,565,647, Llenado, issued January 21 , 1986, having a hydrophobic group containing from about 6 to about 30 carbon atoms, preferably from about 10 to about 16 carbon atoms and a polysaccharide, e.g. a polyglycoside, hydrophilic group containing from about 1.3 to about 10, preferably from about 1.3 to about 3, most preferably from about 1.3 to about 2.7 saccharide units. Any reducing saccharide containing 5 or 6 carbon atoms can be used, e.g., glucose, galactose and galactosyl moieties can be substituted for the glucosyl moieties (optionally the hydrophobic group is attached at the 2-, 3-, 4-, etc. positions thus giving a glucose or galactose as opposed to a glucoside or galactoside). The intersaccharide bonds can be, e.g., between the one position of the additional saccharide units and the 2-, 3-, 4-, and/or 6- positions on the preceding saccharide units.

The preferred alkylpolyglycosides have the formula R2θ(C_nH₂nO)t(glycosyl)_x

wherein R² is selected from the group consisting of alkyl, alkylphenyl, hydroxyalkyl, hydroxyalkylphenyl, and mixtures thereof in which the alkyl groups contain from about 10 to about 18, preferably from about 12 to about 14, carbon atoms; n is 2 or 3, preferably 2; t is from 0 to about 10, preferably 0; and x is from about 1.3 to about 10, preferably from about 1.3 to about 3, most preferably from about 1.3 to about 2.7. The glycosyl is preferably derived from glucose. To prepare these compounds, the alcohol or alkylpolyethoxy alcohol is formed first and then reacted with glucose, or a source of glucose, to form the glucoside (attachment at the 1 -position). The additional glycosyl units can then be attached between their 1 -position and the preceding glycosyl units 2-, 3-, 4- and/or 6- position, preferably predominately the 2-position.

The condensation products of ethylene oxide with a hydrophobic base formed by the condensation of propylene oxide with propylene glycol are also suitable for use as the additional nonionic surfactant systems of the present invention. The hydrophobic portion of these compounds will preferably have a molecular weight of from about 1500 to about 1800 and will exhibit water insolubility. The addition of polyoxyethylene moieties to this hydrophobic portion tends to increase the water solubility of the molecule as a whole, and the liquid character of the product is retained up to the point where the polyoxyethylene content is about 50% of the total weight of the condensation product, which corresponds to condensation with up to about 40 moles of ethylene oxide. Examples of compounds of this type include certain of the commercially-available Plurafac™ LF404 and Pluronic™ surfactants, marketed by BASF.

Also suitable for use as the nonionic surfactant of the nonionic surfactant system of the present invention, are the condensation products of ethylene oxide with the product resulting from the reaction of propylene oxide and ethylenediamine. The hydrophobic moiety of these products consists of the reaction product of ethylenediamine and excess propylene oxide, and generally has a molecular weight of from about 2500 to about 3000. This hydrophobic moiety is condensed with ethylene oxide to the extent that the condensation product contains from about 40% to about 80% by weight of polyoxyethylene and has a molecular weight of from about 5,000 to about 11 ,000.

Antiredeposition and soil suspension agents suitable herein include cellulose derivatives such as methylcellulose, carboxymethylcellulose and hydroxy- ethylcellulose, and homo- or co-polymeric polycarboxylic acids or their salts. Polymers of this type include the polyacrylates and maleic anhydride-acrylic acid copolymers previously mentioned as builders, as well as copolymers of maleic anhydride with ethylene, methylvinyl ether or methacrylic acid, the maleic anhydride constituting at least 20 mole percent of the copolymer. These materials are normally used at levels of from 0.5% to 10% by weight, more preferably from 0.75% to 8%, most preferably from 1% to 6% by weight of the composition.

Other useful polymeric materials are the polyethylene glycols, particularly those of molecular weight 1000-10000, more particularly 2000 to 8000 and most preferably about 4000. These are used at levels of from 0.20% to 5% more preferably from 0.25% to 2.5% by weight. These polymers and the previously mentioned homo- or co-polymeric polycarboxylate salts are valuable for improving whiteness maintenance, fabric ash deposition, and cleaning performance on clay, proteinaceous and oxidizable soils in the presence of transition metal impurities.

It is well-known in the art that free chlorine in tap water rapidly deactivates the enzymes comprised in detergent compositions. Therefore, using chlorine scavenger such as perborate, ammonium sulfate, sodium sulphite or polyethyleneimine at a level above 0.1% by weight of total composition, in the formulas will provide improved through the wash stability of the detergent enzymes. Compositions comprising chlorine scavenger are described in the European patent application 92870018.6 filed January 31 , 1992.

Alkoxylated polycarboxylates such as those prepared from polyacrylates are useful herein to provide additional grease removal performance.

Examples of such salts are polyacrylates of MW 2000-5000 and their copolymers with maleic anhydride, such copolymers having a molecular weight of from 1 ,000 to 100,000. Especially, copolymer of acrylate and methylacrylate such as the 480N having a molecular weight of 4000, at a level from 0.5-20% by weight of composition can be added in the laundry detergent and/or fabric care compositions of the present invention. The compositions of the invention may contain a lime soap peptiser compound, which has preferably a lime soap dispersing power (LSDP), as defined hereinafter of no more than 8, preferably no more than 7, most preferably no more than 6. The lime soap peptiser compound is preferably present at a level from 0% to 20% by weight. A numerical measure of the effectiveness of a lime soap peptiser is given by the lime soap dispersant power (LSDP) which is determined using the lime soap dispersant test as described in an article by H.C. Borghetty and C.A. Bergman, J. Am. Oil. Chem. Soc, volume 27, pages 88-90, (1950). This lime soap dispersion test method is widely used by practitioners in this art field being referred to, for example, in the following review articles; W.N. Linfield, Surfactant science Series, Volume 7, page 3; W.N. Linfield, Tenside surf, det., volume 27, pages 159-163, (1990); and M.K. Nagarajan, W.F. Master, Cosmetics and Toiletries, volume 104, pages 71-73, (1989). The LSDP is the % weight ratio of dispersing agent to sodium oleate required to disperse the lime soap deposits formed by 0.025g of sodium oleate in 30ml of water of 333ppm CaCθ3 (Ca:Mg=3:2) equivalent hardness.

Surfactants having good lime soap peptiser capability will include certain amine oxides, betaines, sulfobetaines, alkyl ethoxysulfates and ethoxylated alcohols.

According to the present invention, this example illustrates the coupling of a perfume citral, hygiene agent glutaraldehyde or insect control agent citronellal to a CBD.

The reaction at equal mol takes place in mild conditions (pH 6 to 9.5, from 1 to 48hours / See for example Wirth, P at al 1991 Biorg.Chem 19, 133, 1991 and Chamow SM et al Bioconjugate chem, 4, 133 1994). The chemicals such as perfume (citral), insect control agent (citronellal) and hygiene agent (glutaraldehyde) are linked to NH2 groups of the CBD, linking region and/or polyreactive linking region via Schiffs base reaction. The reaction could also be completed in anhydrous ethanol that contain a drying agent such as Sodium Sulphate.

In case the CBD possesses more than one Lysine or there is a polyreactive linking region comprising more than one lysine, the reaction is identical with the appropriate number of chemicals per CBD. For example 10 equivalent of aldehyde will be added per mol of CBD from familly III that contain more than 10 Lysines.

For example, the CBD having at least one Lysine, has a NH2 reactive moiety to be linked to perfume. The CBD is non volatile and does not change the character of the aldehyde.

Improved release on dry fabrics is obtained by the slow hydrolysis of the CBD perfume linkage.
