Description

Detergent or cleaning product of stable viscosity

The invention relates to a combination of fatty acids or their salts with a (co) polymer of (meth) acrylic acid in detergents or cleaning agents, which contain surfactant (s) and other usual ingredients of detergents and cleaning agents.

Liquid detergents or cleaning products are often supplied in a thickened form and for this purpose contain a thickener or thickener system.

The thickening effect of the thickeners or thickener systems already known will depend on the detergent or cleaning product to be thickened, for example of the surfactants, electrolytes, solvents or essential oils. Also the pH of the detergent or cleaning product to thicken greatly influences the thickening effect.

The thickeners frequently used are thickeners of the polyacrylate type. These display their best thickening effect on detergents or liquid cleaning products in a pH range of 8 to 9. But in this pH range large oscillations arise in the viscosity of detergents or liquid cleaning products, which can reach up to 1000 mPas. Such sharp oscillations are extremely undesirable in the production industry.

The viscosity of detergents or cleaning products containing fatty acid soaps can be raised within certain limits by reducing the pH. However, considerable portions of non-saponified fatty acids can manifest themselves in the form of turbidity and instability.

US 6,342,472 B1 discloses thickened detergents or cleaning products containing fatty acid soaps and carrying at least 0.5% by weight of a polyacrylate thickener and 13% by weight of a fatty acid salt.

It is an object of the invention to develop a thickened detergent or cleaning product that is stable and / or has a relatively constant viscosity within a wide pH range. This object is achieved with the use of a combination of:

(to)

 from 0.1 to less than 5% by weight of a fatty acid and / or a fatty acid salt and

(b)

 from 0.01 to less than 0.5% by weight of a (co) polymer of (meth) acrylic acid to reduce the viscosity fluctuations of a detergent or liquid cleaning product, containing surfactant (s) and other ingredients usual detergents and cleaning products.

Surprisingly, it has been shown that a marked reduction in the content of fatty acids and / or salts of fatty acids in combination with extremely small amounts of (co) polymer of (meth) acrylic acid leads to detergents or cleaning products, whose viscosity is sufficiently high and, when variations in pH occur, it suffers minor oscillations. In addition, detergents or cleaning products are stable and have no precipitates, turbidity or similar things at all.

It is preferred that the amount of fatty acid and / or fatty acid salt is between 0.5 and 3% by weight and it is more preferred that it be between 0.75 and 1.5% by weight.

It has been found that, by reducing the amount of fatty acid and / or the fatty acid salt, the viscosity oscillations are clearly smaller when there are variations in the pH, without reducing the secondary detergent potency, for example the antiagrisante effect of the detergent or cleaning product.

It is further preferred that the amount of (co) polymer of (meth) acrylic acid is between 0.01 and 0.3% by weight.

These small amounts of (co) polymer of (meth) acrylic acid are also sufficient to stabilize the detergent or cleaning product against phase separation and the formation of clouds or flakes (flocculation). On the other hand, the production costs of the detergent or cleaning product can be reduced as a whole due to the lower raw material costs due to polyacrylate.

It is further preferred that the detergent or cleaning product also contain 0.001 to 3% by weight of a silicone compound.

Detergents and cleaning products usually contain silicone compounds, especially as foaming inhibitors. It has been especially surprisingly evident that small amounts of (co) polymer of (meth) acrylic acid in combination with selected amounts of fatty acid and / or fatty acid salt stabilize liquid detergents and cleaning products that carry a compound of silicone against the precipitation of the silicone compound, for example in the form of clouds, flakes or specks.

In a preferred embodiment, the detergent or cleaning product contains from 0.01 to 5% by weight of a perfume (fragrance). The chosen amounts of fatty acid and / or fatty acid salt in combination with small amounts of (co) polymer of (meth) acrylic acid lead to detergents or liquid cleaning products, in which the fragrance exerts a clearly reduced influence on the viscosity.

Especially stable detergents or cleaning products with small viscosity fluctuations can also be obtained when pH variations occur, if the detergent or cleaning product contains 0.1 to 15% by weight of glycerin, in addition to the combination of (salt of ) fatty acid and (co) polymer of (meth) acrylic acid.

A method of manufacturing a detergent or cleaning product with smaller viscosity oscillations, containing surfactant (s) and other usual ingredients of detergents or cleaning products, in which they are added to the product (a) of 0 is also described , 1 to less than 5% by weight of a fatty acid and / or a salt of fatty acid and (b) of 0.01 to less than 0.5% by weight of a (co) polymer of (meth) acid acrylic. A detergent or cleaning product manufactured in this way has lower viscosity oscillations, especially when there is a variation in the pH of the detergent or cleaning product in the range between 7 and 9.

Another aspect concerns the use of the detergent or cleaning product for washing and / or cleaning large (flat) textile structures.

The invention relates to the use of a combination of (a) from 0.1 to less than 5% by weight of a fatty acid and / or a fatty acid salt and (b) from 0.01 to less than 0 , 5% by weight of a (co) polymer of (meth) acrylic acid to reduce the viscosity fluctuations of a detergent or liquid cleaning product, which contains surfactant (s) and other usual detergent or cleaning agent ingredients. The oscillation of viscosity is reduced with special efficiency when the pH of the detergent or liquid cleaning product undergoes a variation within the range of 7 to 9. The invention further relates to the use of a combination of (a) of 0, 1 to less than 5% by weight of a fatty acid and / or a salt of fatty acid and (b) of 0.01 to less than 0.5% by weight of a (co) polymer of (meth) acrylic acid to stabilize a detergent or liquid cleaning product, which contains surfactant (s), a silicone compound and other usual ingredients of detergents or cleaning agents.

A detergent or cleaning product contains a combination of:

(to)

 0.1 to less than 5% by weight of a fatty acid and / or a fatty acid salt and

(b)

 from 0.01 to less than 0.5% by weight of a (co) polymer of (meth) acrylic acid.

As an essential ingredient, liquid detergents or cleaning products contain a fatty acid and / or fatty acid salt. Saturated and unsaturated fatty acids are suitable, for example lauric acid, myristic acid, palmitic acid, stearic acid, erucic acid (hydrogenated) and behenic acid and especially mixtures derived from natural fatty acids, for example coconut oil, of palm kernel, olive or tallow fat, as well as its salts.

The fatty acid salts may be present in the form of sodium, potassium or ammonium salts and in the form of soluble salts of organic bases, for example mono-, di- or triethanolamine. Salts of fatty acids are preferably present in the form of sodium or potassium salts, especially in the form of sodium salts.

The amount of fatty acid and / or fatty acid salt is between 0.1 and less than 5% by weight, preferably between 0.25 and 4% by weight, more preferably between 0.5 and 3% by weight, more preferably still between 0.6 and 2% by weight and with special preference between 0.75 and 1.5% by weight, percentages referred in each case to the total weight of the product.

Apart from the fatty acid and / or the fatty acid salt, a detergent or cleaning agent necessarily contains from 0.01 to less than 0.5% by weight of a (meth) acrylic acid (co) polymer. Suitable (co) polymers of acrylic and methacrylic acids include, for example, high molecular weight crosslinked homopolymers carrying a polyalkenyl polyether, especially an allyl ether of sucrose, pentaerythrite or propylene, (INCI nomenclature of the "International Dictionary" of Cosmetic Ingredients "of the" The Cosmetic, Toiletry and Fragrance Association "(CTFA): Carbomer, which are also called carboxyvinyl polymers, among others, the company 3V Sigma

Other suitable polymers are the (co) polymers of (meth) acrylic acid of the Sokalan® type (supplied by BASF), for example Sokalan® ES 95048.

The amount of (co) polymer of (meth) acrylic acid is between 0.01 and less than 0.5% by weight, preferably between 0.01 and 0.3% by weight.

It is preferred that the (co) polymer of (meth) acrylic acid is not a polymer of pure acrylic acid or of pure methacrylic acid.

Apart from the fatty acid and / or the fatty acid salt and the (co) polymer of (meth) acrylic acid, the detergent or cleaning product contains surfactant (s), anionic, non-ionic, bipolar (zwitterionic) surfactants can be used and / or amphoteric. Mixtures of anionic and non-ionic surfactants are preferred. The total content of surfactants within the detergent or liquid cleaning product is preferably at a value of less than 40% by weight and with special preference less than 35% by weight, percentages referring to the total weight of the liquid detergent.

As non-ionic surfactants, primary alcohols are preferred, preferably alkoxylated, with ethoxylated advantage, preferably having 8 to 18 C atoms and on average 1 to 12 moles of ethylene oxide (EO) per mole of alcohol, in which the alcohol moiety can be linear or preferably branched with methyl in position 2, or it can contain a mixture of linear and branched moieties with methyl, as they normally occur in the oxoalcohol moieties. However, ethoxylates of alcohols having linear residues, obtained from naturally occurring alcohols having 12 to 18 C atoms, eg from coconut, palm, tallow fatty alcohols, are especially preferred or oleyl alcohol and on average 2 to 8 moles of EO per mole of alcohol. Among the preferred ethoxylated alcohols are, for example, C12-14 alcohols bearing 3 EO, 4 EO or 7 EO, C9-11 alcohols with 7 EO, C13-15 alcohols with 3 EO, 5 EO, 7 EO or 8 EO, C12-18 alcohols with 3 EO, 5 EO or 7 EO and mixtures thereof, such as mixtures of C12-14 alcohols with 3 EO and C12-18 alcohols with 7 EO. The degrees of ethoxylation indicated are statistical average values, which, for a specific product, can be an integer or fractional number. Preferred alcohol ethoxylates have a narrow homolog distribution (narrow range ethoxylates, NRE). In addition to these non-ionic surfactants, fatty alcohols having more than 12 moles of EO can also be used. Examples of this are tallow fatty alcohols carrying 14 EO, 25 EO, 30 EO or 40 EO. Non-ionic surfactants which in their molecule contain both EO and PO groups can also be used according to the invention. In this case, block copolymers, consisting of EO-PO units or PO-EO units, but also EO-PO-EO copolymers and PO-EO-PO can be used. Obviously, mixed alkoxylated nonionic surfactants can also be used, in which the EO and PO units do not form blocks, but are statistically distributed in the polymer. Such products can be obtained by simultaneous grafting of ethylene oxide and propylene oxide units in fatty alcohols.

Alkyl glycosides of the general formula RO (G) x may also be used as additional non-ionic surfactants, in which R means a primary linear aliphatic moiety or branched with methyl, especially an aliphatic moiety of 8 to 22 C atoms, preferably from 12 to 18, branched with methyl at position 2 and G is the symbol of a glycan unit of 5 or 6 C atoms, preferably glucose. The degree of oligomerization x, which indicates the distribution of monoglycosides and oligoglycosides, is any number between 1 and 10; x is preferably between 1.2 and 1.4. The alkyl glycosides are moderate surfactants, already known.

Another group of non-ionic surfactants that can be used preferably, either as a single non-ionic surfactant, whether in combination with other non-ionic surfactants, is formed by alkyl esters of alkoxylated fatty acids, preferably ethoxylated or ethoxylated and propoxylates, preferably those bearing 1 to 4 carbon atoms in the alkyl chain, especially fatty acid methyl esters.

Nonionic surfactants of the amine oxide type may also be suitable, for example N-cocoalkyl-N, N-di-methylamine oxide and N-tallow-alkyl-N, N-dihydroxyethylamine oxide and alkanolamide type of fatty acids. The amount of these non-ionic surfactants is preferably at a value not exceeding that of ethoxylated fatty alcohols, especially not more than half of the latter.

Other suitable surfactants are the amides of the polyhydroxy fatty acids of the formula (I): in which RCO means an aliphatic acyl moiety of 6 to 22 carbon atoms, R1 means hydrogen, an alkyl moiety

or hydroxyalkyl of 1 to 4 carbon atoms and [Z] means a linear or branched polyhydroxyalkyl moiety of 3 to 10 carbon atoms and 3 to 10 hydroxyl groups. Polyhydroxy fatty acid amides are known compounds, which are usually obtained by reductive amination of a reducing sugar with ammonia, an alkylamine or an alkanolamine and subsequent acylation with a fatty acid, a fatty acid alkyl ester or a fatty acid chloride.

The compounds of the formula (II) also belong to the group of polyhydroxy fatty acid amides:

wherein R means a linear or branched alkyl or alkenyl moiety of 7 to 12 carbon atoms, R1 means a

A linear, branched or cyclic alkylene moiety or an arylene moiety of 2 to 8 carbon atoms and R2 means a linear, branched or cyclic alkyl moiety or an aryl moiety or an oxy-alkyl moiety of 1 to 8 carbon atoms, with preferred the C1-4 alkyl or phenyl moieties and [Z] means a linear polyhydroxyalkyl moiety, whose alkyl chain is substituted by at least two hydroxyl groups, or alkoxylated derivatives, preferably ethoxylated or propoxylated, of this moiety.

[Z] is preferably obtained by reductive amination of a reduced sugar, for example glucose, fructose, maltose, lactose, galactose, mannose or xylose. By reaction with a fatty acid methyl ester in the presence of an alkoxide as a catalyst, the compounds substituted on N by alkoxy or by aryloxy can be converted into the desired polyhydroxy fatty acid amides.

The content of non-ionic surfactants in the detergent or cleaning product is preferably between 3 and 30% by weight, preferably between 6 and 20% by weight and especially between 9 and 15% by weight, percentage referred in case to detergent or cleaning product.

Apart from non-ionic surfactants, the detergent or cleaning product may also contain anionic surfactants. As anionic surfactants, for example, those of the sulphonate and sulfate type are used. As sulphonate-type surfactants, preference is given to preference to (C9-13 alkyl) benzenesulfonates, olefinsulfonates, i.e. mixtures of alkene- and hydroxyalkanesulfonates and disulfonates, for example those resulting from the sulfonation of C12-18 double-bond monoolefins terminal or interior with gaseous sulfur trioxide and subsequent alkaline or acid hydrolysis of sulfonation products. Also suitable are alkanesulfonates, which are obtained from C12-18 alkanes, for example by sulphochlorination or sulfoxidation and subsequent hydrolysis or neutralization. Also suitable are esters of sulfo-fatty acids (stersulfonates), eg esters

d d-sulfonated methyl of hydrogenated coconut, palm kernel or tallow fatty acids.

Other suitable anionic surfactants are glycerin esters of sulfonated fatty acids. Fatty acid glycerin esters are understood as mono-, di- and tri-esters and mixtures thereof, which are obtained during the manufacture by esterification of a monoglycerin with 1-3 moles of fatty acid or by transesterification of triglycerides with 0, 3-2 moles of glycerin. Preferred sulfonated fatty acid glycerin esters are the sulfonation products of saturated fatty acids of 6 to 22 carbon atoms, for example capronic acid, caprylic acid, capric acid, myristic acid, lauric acid, acid palmitic acid, stearic acid or acid

45 behenic.

As alk (en) ilsulfates, alkaline salts and especially sodium salts of sulfuric acid half esters with C12-C18 fatty alcohols, for example coconut fatty alcohols, tallow fatty alcohols, lauric alcohol, myristic alcohol, are preferred. cetyl or stearic or the C10-C20 oxoalcohols and the secondary alcohol half esters of these chain lengths. Also preferred are alkylsulfates of the aforementioned chain lengths, which contain a synthetic, straight-chain alkyl moiety, obtained by petrochemical synthesis, which have a degradation behavior similar to that of suitable compounds based on raw materials of the fat chemistry (C12-C16 alkyl) sulfates are of technical interest and (C12-C15 alkyl) sulfates and (C14-C15 alkyl) sulfates are preferred. The appropriate anionic surfactants are also 2,3

alkyl sulfates, which are obtained, for example, in accordance with US Pat. Nos. 3,234,258 or 5,075,041 and which the Shell Oil Company supplies under the trade name of DAN®.

Also suitable are sulfuric acid monoesters of C7-21 straight or branched chain alcohols, ethoxylated with 1-6 moles of ethylene oxide, for example C9-11 alcohols branched in position 2 with methyl, ethoxylated on average with 3, 5 moles of ethylene oxide (EO) or ethoxylated C12-18 fatty alcohols with 1-4 moles of EO. Due to their great foaming power they are used in cleaning products only in relatively small quantities, for example in amounts of 1 to 5% by weight.

Other suitable anionic surfactants are also the salts of the adkylsulfosuccinic acids, also called sulfosuccinates or esters of sulfosuccinic acids, which are monoesters and / or diesters of sulfosuccinic acid with alcohols, preferably with fatty alcohols and especially with ethoxylated fatty alcohols. Preferred sulfosuccinates contain residues of C8-18 fatty alcohols or mixtures thereof. Especially preferred sulphosuccinates contain a fatty alcohol residue, which is derived from ethoxylated fatty alcohols, which, in themselves, constitute non-ionic surfactants (see above description). Among them, sulfosuccinates, whose fatty alcohol residues are derived from ethoxylated fatty alcohols with narrow homolog distribution, are preferred. It is also possible to use the alkyl (en) ilsuccinic acids preferably having 8 to 18 carbon atoms in the alkyl (en) yl chain or its salts.

Anionic surfactants may be present in the form of sodium, potassium or ammonium salts and in the form of soluble salts of organic bases, for example mono-, di- or triethanolamine. Anionic surfactants are preferably present in the form of sodium or potassium salts, especially in the form of sodium salts.

The content of anionic surfactants in a detergent or cleaning product can be between 0.1 and 30% by weight, a percentage based on the total weight of the detergent or cleaning product.

In addition to the fatty acid and / or the fatty acid salt, the (co) polymer of (meth) acrylic acid and the surfactant (s), the detergent or cleaning agent may contain other ingredients, which continue to improve the technical properties of application and / or the aesthetic properties of the detergent or cleaning product. In the context of the present invention, the detergent or cleaning product also preferably contains one or more compounds from the group of support substances (builder), bleach, enzymes, electrolytes, non-aqueous solvents, buffers or substances for adjusting the pH, aromas, fragrances, dyes, fluorescent agents, colorants, hydrotropic substances, foaming inhibitors, silicone oils, anti-redeposition agents, grating inhibitors, shrinkage inhibitors, anti-wrinkle agents, color transfer inhibitors, antimicrobial active substances, germicides, fungicides, antioxidants, preservatives, corrosion inhibitors, antistatics, bitter agents, ironing aids, water repellent and impregnating agents, swelling and anti-slip agents, UV softeners and absorbents.

As support materials (builder), which may be present in the detergent or cleaning product of the invention, mention may be made in particular of silicates, aluminum silicates (especially zeolites), carbonates, salts of different acids. and organic polycarboxylic as well as mixtures of these materials.

Appropriate laminar, crystalline sodium silicates have the general formula NaMSixO2x + 1.yH2O, in which M means sodium or hydrogen, x is a number from 1.9 to 4 and “y” is a number from 0 to 20, being the preferred values of x 2, 3 or 4, for the replacement of zeolites or phosphates. Crystalline layered silicates of the indicated formula are those, in which M means sodium and x adopts values 2 or 3. Not only sodium ßdisilicates but also sodium Na-Si2O5-yH2O o-disilicates are especially preferred.

Amorphous sodium silicates can also be used, which have a Na2O: SiO2 molar ratio of 1: 2 to 1: 3.3, preferably 1: 2 to 1: 2.8 and especially 1: 2 to 1: 2, 6, which have a delayed dissolution behavior and which have secondary detergent properties. The delayed dissolution behavior with respect to conventional amorphous sodium silicates can be generated in different ways, for example with a surface treatment, with the formulation, with compaction / compression or with extreme drying. In the context of this invention, the term "amorphous" is understood to mean that silicates subjected to X-ray analysis do not show clear radiological reflections, typical of crystalline substances, but in any case have one or more scattered X-ray maxima. , which have an amplitude of several degrees of diffraction angle. However, properties of support substances (builder) can even be achieved, especially when the silicate particles can provide diffuse or even sharp maximums in electronic diffraction tests. This can be interpreted in the sense that the products have microcrystalline regions of a size between tens and a few hundred nm, with a maximum value of 50 nm and especially a maximum of 20 nm being preferred. Especially preferred are compacted amorphous silicates, formulated amorphous silicates and radiologically amorphous silicates dried in an extreme manner.

The synthetic zeolite, of fine crystals, which contains fixed water and is used, is preferably zeolite A and / or P. Zeolite type P is especially preferred zeolite MAP® (trade name of the

Crosfield company). However, zeolite X and mixtures of zeolites A, X and / or P. are also suitable. It is a commercial product that can be used especially preferably in the context of the present invention for example co-crystallization of zeolite X and zeolite A (approx. 80% by weight of zeolite X), which SASOL company

supplied under the trade name of VEGOBOND® AX and can be described with the formula:

nNa2O · (1-n) K2O · Al2O3. (2 - 2.5) SiO2 · (3.5 - 5.5) H2O where n = 0.90-1.0

The zeolite can be used as a spray-dried powder or also as a stabilized suspension without drying, still wet when leaving production. In the case where the zeolite is used as a suspension, said zeolite may contain small amounts of non-ionic surfactants as stabilizers, for example from 1 to 3% by weight, percentages referred to zeolite, of C12-C18 fatty alcohols ethoxylates carrying 2 to 5 ethylene oxide groups, C12-C14 fatty alcohols carrying 4 or 5 ethylene oxide groups or ethoxylated isotridecanoles. Suitable zeolites have an average particle size of less than 10 μm (volume distribution; measurement method: Coulter counter) and preferably contain 18 to 22% by weight, in particular 20 to 22% by weight, of water set.

Obviously phosphates already known in general can also be used as support substances (builder), in the event that such use should not be avoided for ecological reasons. Sodium salts of orthophosphates, pyrophosphates and especially tripolyphosphates are especially suitable.

Organic support substances that can be used are, for example, polycarboxylic acids usable in the form of sodium salts, polycarboxylic acids being those carboxylic acids that carry more than one acidic functional group. They are for example citric acid, adipic acid, succinic acid, glutaric acid, malic acid, tartaric acid, maleic acid, fumaric acid, saccharic acid, aminocarboxylic acids, nitrilotriacetic acid (NTA), assuming there is no Ecological objections that prevent its use, as well as mixtures thereof. Preferred salts are salts of polycarboxylic acids, for example citric acid, adipic acid, succinic acid, glutaric acid, tartaric acid, saccharic acid and mixtures thereof.

The acids themselves can also be used. Apart from its support or vehicle (builder) effect, acids normally possess the properties of an acidifying component and therefore serve, for example in the granules of the invention, to adjust detergents or cleaning products to a low value pH or moderate. At this time, it is especially worth mentioning citric acid, succinic acid, glutaric acid, adipic acid, gluconic acid and any mixture thereof. Other known pH regulators are sodium hydrogen carbonate and sodium hydrogen sulfate.

Polymeric polycarboxylates, for example alkali metal salts of polyacrylic acid or polymethacrylic acid, for example, having a relative molecular weight of 500 to 70,000 g / mol are also suitable.

The indicated molecular weights of the polymeric polycarboxylates are, in the sense of this document, average weight molecular weights Mw of the corresponding acid form, which are mainly determined by gel infiltration chromatography (GPC), using a UV detector. The measurement is carried out using as an external standard a polyacrylic acid, which due to its structural affinity with the analyzed polymers provides realistic values of molecular weights. These data differ markedly from the molecular weight data, in which polystyrene sulfonic acids are used as the standard. The molecular weights determined against polystyrene sulfonic acids are generally generally much higher than the molecular weights indicated herein.

Due to their better solubility, short chain polyacrylates, having molecular weights between 2000 and 10,000 g / mol and with special preference between 3000 and 5000 g / mol, may be preferred within this group.

Suitable polymers may also contain compounds, which are formed wholly or partially by units of vinyl alcohol or its derivatives.

Copolymer polycarboxylates are also suitable, especially those of acrylic acid with methacrylic acid and those of acrylic acid or methacrylic acid with maleic acid. Copolymers of acrylic acid with maleic acid, containing 50 to 90% by weight of acrylic acid and 50 to 10% by weight of maleic acid, have been shown to be especially suitable. Their relative molecular weights, referred to free acids, are generally between 2000 and 70,000 g / mol, preferably between 20,000 and 50,000 g / mol and especially between 30,000 and 40,000 g / mol. The polycarboxylates (co) polymers can be used in the form of an aqueous solution or, preferably, in the form of a powder.

To improve water solubility, the polymers may also contain allylsulfonic acids, for example allyloxybenzenesulfonic acid and metalylsulfonic acid, as monomers.

Also especially preferred are biodegradable polymers having more than two distinct monomer units, for example those which, as monomers, contain salts of acrylic acid and maleic acid and vinyl alcohol or derivatives of vinyl alcohol, or which, as monomers, contain salts of acrylic acid and 2-alkylsulfonic acid as well as sugar derivatives.

Other preferred copolymers are those which, as monomers, preferably contain acrolein and acrylic acid / salts of acrylic acid or acrolein and vinyl acetate.

It is also worth mentioning as preferred carrier substances (builder) the polymeric aminodicarboxylic acids, their salts or their previous synthetic compounds. Especially preferred are polyaspartic acid and its salts, which, apart from the properties of complementary support substances (cobuilder), also display a bleaching stabilizing action.

Other suitable carrier substances (builder) are polyacetals, which can be obtained by reacting dialdehydes with polycarboxylic acids, having 5 to 7 C atoms and at least 3 hydroxyl groups, for example those described in European patent application EP 0 280 223. Preferred polyacetals are obtained from dialdehydes, for example glyoxal, glutaraldehyde, terephthalaldehyde and mixtures thereof, and polyolcarboxylic acids, such as gluconic acid and / or glucoheptonic acid.

Other suitable organic support substances (builder) are dextrins, for example carbohydrate oligomers and polymers, which can be obtained by partial hydrolysis of starches. Hydrolysis can be carried out by usual processes, for example, processes catalyzed by acids or enzymes. Hydrolysis products preferably have average molecular masses between 400 and 500,000 g / mol. A polysaccharide having a dextrose equivalent (SD) between 0.5 and 40, in particular between 2 and 30, is preferred, with DE being the usual index of the reducing effect of a polysaccharide compared to dextrose, which has a DE of 100. It is possible to use not only maltodextrins that have a DE between 3 and 20 and dry glucose syrups that have a DE between 20 and 37, but also the so-called yellow dextrins and white dextrins that have larger molecular masses, in the range of 2,000 to 30,000 g / mol.

The oxidized derivatives of such dextrins are reaction products with oxidants, which are capable of oxidizing at least one alcohol functional group of the saccharide ring and converting it into a carboxylic acid functional group. An oxidized oligosaccharide is also suitable. An oxidized product on C6 of the saccharide ring can be especially advantageous.

Oxydisuccinates and other derivatives of the disuccinates, preferably ethylenediamine disuccinates, are also suitable support substances (builder). N, N'-ethylenediamine disuccinate (EDDS), is preferably used in the form of its sodium or magnesium salts. In this context, glycerin disuccinates and glycerin trisuccinates are also preferred.

Other usable organic support substances (builder) are acetylated hydroxycarboxylic acids and their salts, which may be present in the form of lactone and contain at least 4 carbon atoms, at least one hydroxyl group and at most two acidic groups.

Anyway, for aesthetic reasons soluble organic support substances are used, for example citric acid, preferably in thickened detergents or liquid cleaning products.

Among the compounds that act as bleach, which deliver H2O2 to water, sodium perborate tetrahydrate and sodium perborate monohydrate are of particular importance. Other usable bleaches are, for example, sodium percarbonate, peroxypyrophosphates, perhydrated citrates, and peracid salts or peracids that release H2O2, for example, perbenzoates, peroxophthalates, diperazelaic acid, phthaliminopenacid or diperdoperoxyethanoic acid, 4-diimodioperoxyethane, , 5-phthalimidoperoxopentanoic acid, 6-phthalimidoperoxohexanoic acid, 7-phthalimidoperoxoheptanoic acid, N, N'-terephthaloyl-di-6-aminoperoxohexanoic acid and mixtures thereof. Preferred peracids include phthalimidoperoxoalkanoic acids, especially 6-phthalimidoperoxohexanoic acid (PAP). It may be preferred that the bleach has a coating (lining), which does not dissolve until the moment of the washing process itself and then the bleach is released.

The amount of bleach is preferably between 0.5 and 25% by weight, a percentage based on the total weight of the detergent or cleaning product.

To wash at temperatures of 60 ° C and below and achieve an improved bleaching effect, bleach activators can be incorporated into detergents and cleaning agents. As bleaching activators, compounds can be used, which under the conditions of perhydrolysis generate aliphatic peroxocarboxylic acids. Preferred are polycylated alkylenediamines, especially tetraacetylethylenediamine (TAED), acylated derivatives of triazine, especially 1,5-diacetyl-2,4-dioxohexahydro-1,3,5-triazine (DADHT), acylated glycoluryls , especially tetraacetylglycoluril (TAGU), N-acylimides, especially N-nonanoylsuccinimide (NOSI), acylated phenolsulfonates, especially n-nonanoyl- or isononanoyloxybenzenesulfonate (n- or iso-NOBS), the anhydrides of carboxylic acids, especially phthalic anhydride, acylated polyhydric alcohols, especially triacetin, ethylene glycol diacetate and 2,5-diacetoxy-2,5-dihydrofuran.

In addition to conventional bleach activators or instead so-called bleach catalysts can also be incorporated into detergents and cleaning agents. These compounds are transition metal salts or transition metal complexes that intensify bleaching, for example salene complexes or carbonyl complexes of Mn, Fe, Co, Ru or Mo. Bleach catalysts can also be used complexes of Mn, Fe, Co, Ru, Mo, Ti, V and Cu with tripod ligands containing N as well as the amino complexes of Co, Fe, Cu and Ru.

If the detergent or liquid cleaning product has to contain a bleach, a bleach activator and / or a bleach catalyst, then it is especially advantageous if they are present in encapsulated form in the detergent or cleaning product.

The detergent or cleaning product may contain a thickener. The thickener can be, for example, an xanthan gum, gellan gum, guar seed meal, alginate, carrageenan, carboxymethyl cellulose, bentonite, wellane gum, algorithrobo seed meal, agar-agar, tragacanth, gum arabic, pectins, poliosae, starch , dextrins, gelatin, casein. However, modified natural substances, for example modified starches and celluloses, can also be used as thickeners, for example, carboxymethyl cellulose and other cellulose ethers, hydroxyethyl cellulose, hydroxypropyl cellulose; seed meal ethers.

A fatty alcohol is also considered as a thickener. Fatty alcohols may be branched or not and be of natural or petrochemical origin. Preferred fatty alcohols have a C chain length of 10 to 20 C atoms, preferably 12 to 18. Mixtures of different C chain lengths are preferably used, for example tallow fatty alcohols or alcohols. Coconut fatty They are

Examples of this are Lorol® Special (C12-14-ROH) and Lorol® Technical (C12-18-ROH) (both supplied by Cognis).

The detergent or cleaning product may contain from 0.01 to 3% by weight and preferably from 0.1 to 1% by weight of thickener. The amount of thickener used will depend on the type of thickener and the desired degree of thickening. However, preferred detergents or cleaning agents do not contain thickener.

The detergent or cleaning product may contain enzymes. Enzymes are especially taken into account those of the hydrolase groups, for example proteases, esterases, lipases or enzymes that have lipolytic action, amylases, cellulases and other glycosylhydrolases, hemicellulases, cutinases, � - glucanases, oxidases, peroxidases, mananases, perhydrolases and / or lacases and mixtures of the enzymes mentioned. All these hydrolases contribute during the washing to the removal of stains, such as protein, fat or sugar stains and gray areas. Cellulases and other glycosylhydrolases can also contribute to eliminating the fluff that has formed and also microfibrils, preserving the color and increasing the softness of the textile material. Oxirreductases can be used for bleaching or to prevent color transfer. Enzymatic active substances obtained from bacterial or fungal strains are especially indicated, for example Bacillus subtilis, Bacillus licheniformis, Streptomyces griseus and Humicola insolens. Preferably, subtilisin-like proteases and especially proteases obtained from Bacillus lentus are used. Of particular interest are mixtures of enzymes, for example of protease and amylase or of protease and lipase or of enzymes of lipolytic action or protease and cellulase or of protease, lipase or of enzymes of lipolytic action with cellulase, but in especially mixtures containing protease and / or lipase or mixtures of enzymes of lipolytic action. Examples of such enzymes of lipolytic action are known cutinases. Peroxidases or oxidases may also be appropriate in some cases. They belong to the appropriate amylases especially the damilasas, the isoamilasas, the pululanasas and the pectinasas. Cellobiohydrolases, endoglucanases and �-glucosidases, also called cellobiases, or mixtures thereof are preferably used as cellulases. The different types of cellulases are distinguished by their CMcasa and avicelase activities, therefore the desired activities can be adjusted using suitable mixtures of cellulases.

Enzymes may be encapsulated or adsorbed on support substances, to protect themselves from premature destruction. The portion of enzymes, of liquid enzymatic formulation or formulations or of enzymatic granules within a detergent or cleaning product can be for example between 0.01 and 5% by weight, preferably between 0.12 and 2, 5% by weight.

A large number of the most diverse salts can be used as electrolytes of the group of inorganic salts. Preferred cations are those of alkali and alkaline earth metals, preferred anions are halides and sulfates. From the point of view of the production technique, the use of NaCl or MgCl2 in the detergent or cleaning product of the invention is preferred. The electrolyte portion within the detergent or cleaning product is usually between 0.1 and 5% by weight.

Non-aqueous solvents, which can be used in the detergent or cleaning product, come for example from the group of monovalent alcohols, alkanolamines or glycol ethers, in the event that they are miscible with water in the concentration range provided for the use. The solvents are preferably chosen from ethanol, n- or i-propanol, butane, ethylene glycol methyl ether, ethylene glycol ethyl ether, ethylene glycol propyl ether, ethylene glycol monobutyl ether, diethylene glycol methyl ether, diethylene glycol ethyl ether, the methyl-, ethyl- or propyl ether of propylene glycol, the monomethyl- or -ethyl ether of dipropylene glycol, monomethyl- or -ethyl ether of dipropylene glycol, monomethyl- or -ethyl ether of di-isopropylene glycol, methoxy-, ethoxy- or butoxytriglycol, 1-butoxyiethoxy-2-propanol, 3-methyl-3-methoxybutanol, t-butyl ether of propylene glycol and mixtures of these solvents. Non-aqueous solvents can be used in the detergent or cleaning product in amounts between 0.1 and 15% by weight, but preferably in amounts less than 12% by weight and especially less than 9% by weight.

It is preferred that the detergent or cleaning product contain certain amounts of polyol as a non-aqueous solvent. It is preferred that the product contains 0.1 to 15% by weight and preferably 2 to 10% by weight of a polyol. The polyol may encompass glycerin, 1,2-propanediol, 1,3-propanediol, ethylene glycol, diethylene glycol and / or dipropylene glycol, with glycerin being preferred. It may be preferred that the detergent or cleaning product contains a mixture of at least two polyols. A mixture of glycerin and diethylene glycol is preferred.

To adjust the pH of the detergent or cleaning product at the desired range, the use of buffer or pH adjustment compounds may be indicated. All known acids or solutions of hydroxides (bleach) can be used here, in the event that there are no objections of a technical, ecological or user protection nature that impede their use. Normally the amount of the pH adjustment compound does not exceed 10% by weight of the total formulation.

The pH of the detergent or cleaning product is preferably between 4 and 10 and especially between 5.5 and 8.8.

Liquid detergents or cleaning products have viscosities between 250 and 4000 mPas, with viscosities between 500 and 2000 mPas being especially preferred. The viscosity is determined at 20 ° C on a Brookfield LVT-II viscometer with rod 3, which rotates at 20 rpm.

In a preferred embodiment, the detergent or cleaning product contains one or more fragrances in an amount that is usually less than 5% by weight and is preferably between 0.01 and 3% by weight, especially between 0.3 and 1.5% by weight.

As essential oils or fragrances, individual aromatic compounds can be used, eg synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type. However, mixtures of various fragrances are used with preference, which together generate an attractive aromatic note. These essential oils may also contain mixtures of natural fragrances, which can be obtained from plant sources.

To improve the aesthetic impression of the detergent or cleaning product, it may be colored with appropriate dyes. Preferred dyes, the choice of which does not pose a problem to experts, have great storage stability, are inert with respect to the other ingredients of detergents or cleaning agents and with respect to light and do not have a substantivity (solidity) accused with respect to textile fibers, so that they do not dye them.

As foaming inhibitors, which can be used in detergents or cleaning agents, for example, soaps, paraffins or silicone compounds, especially silicone oils, which may eventually be in the form of emulsions, are taken into account.

The soil repellents polymers, also called appropriate anti-redeposition agents, are for example cellulose ethers, for example methyl cellulose and methyl hydroxypropyl cellulose, which carry a portion of methoxy groups comprised between 15 and 30% by weight and hydroxypropyl groups from 1 to 15% by weight, percentages referring to the weight of non-ionic cellulose ethers, as well as polymers of phthalic acid and / or terephthalic acid or its derivatives already known in the state of the art, especially terephthalate polymers of ethylene and / or of polyethylene glycol terephthalates or the anionic and / or nonionic modified derivatives thereof. Appropriate derivatives include sulfonated derivatives of the polymers of phthalic acid and terephthalic acid.

Optical bleaches (also called "white toners") can be added to detergents or cleaning agents to remove graying and yellowing of treated textile materials. These compounds are absorbed in the fibers and produce a clearing and an apparent bleaching effect, since they transform the invisible ultraviolet radiation into visible long wave light, whereby the ultraviolet light absorbed from the solar radiation is re-emitted in the form of fluorescence slightly bluish and together with the yellow tone of the clothing that has suffered the graying or yellowing gives the impression of a pure white color. Appropriate compounds are derived, for example, from the group of compounds formed by 4,4'-diamino-2,2'-stilbenedisulfonic acids (flavonic acids), 4,4'styryl-biphenylene, methylumbelliferones, coumarin, dihydroquinolinone, 1,3-diarylpyrazoline, naphthalic acid amides, naphthalic acid imides, benzoxazole, bencisoxazole and benzimidazole systems as well as heterogeneous substituted pyrene derivatives. Optical bleaches are normally used in amounts between 0% and 0.3% by weight, percentages referring to the finished product.

Grating inhibitors have the function of keeping the dirt removed from the fibers in suspension in the bath and, thus, preventing said dirt from being reabsorbed. Water-soluble colloids, usually of an organic nature, for example mucilage, gelatin, ethersulfonic acid salts of starches or cellulose or acidic ester salts of sulfuric acid of cellulose or of the cellulose are suitable for this purpose. starch. Polyamides that carry acidic groups are also suitable for this purpose. Soluble starch preparations and other of the newly named starch products may also be used, eg degraded starches, aldehyde starches, etc. Polyvinylpyrrolidone can also be used. However, cellulose ethers of the carboxymethylcellulose (Na salt), methylcellulose, hydroxyalkylcellulose and mixed ethers type are preferably used, for example methylhydroxyethylcellulose, methylhydroxypropylcellulose, methylcarboxymethylcellulose and mixtures thereof in an amount of 0.1 to 5% by weight, percentages referring to the weight of the detergent or cleaning product.

In order to effectively suppress the start-up and / or transfer of the dyes from some textile materials to others during the washing and / or cleaning of colored textile materials, the detergent or cleaning product may contain a color transfer inhibitor. It is preferred that the color transfer inhibitor be a cyclic amines polymer or copolymer, for example vinyl pyrrolidone and / or vinylimidazole. Suitable polymers such as color transfer inhibitors include polyvinylpyrrolidone (PVP), polyvinylimidazole (PVI), vinylpyrrolidone copolymers and vinylimidazole (PVP / PVI), poly (vinylpyridine N-oxide), poly ( N-carboxymethyl-4-vinylpyridinium chloride) and mixtures thereof. As color transfer inhibitors, polyvinylpyrrolidone (PVP), polyvinylimidazole (PVI) or copolymers of vinyl pyrrolidone and vinylimidazole (PVP / PVI) are especially preferred. The polyvinylpyrrolidones (PVP) used preferably have an average molecular weight between 2,500 and 400,000 and with commercial products that for example the company ISP Chemicals supplies under the names of PVP K 15, PVP K 30, PVP K 60 or PVP K 90 or the BASF company with the

names of Sokalan® HP 50 or Sokalan® HP 53. The copolymers used for vinyl pyrrolidone and vinylimidazole (PVP / PVI) preferably have a molecular weight between 5,000 and 100,000. There is a PVP / PVI polymer that is a commercial product, supplied for example by the company BASF under the name of Sokalan® HP 56.

The amount of color transfer inhibitor, based on the total weight of the detergent or cleaning product, is preferably between 0.01 and 2% by weight, preferably between 0.05 and 1% by weight and with special preference between 0.1 and 0.5% by weight.

Alternatively, as color transfer inhibitors, enzymatic systems, formed by a peroxidases and hydrogen peroxide or a substance that delivers hydrogen peroxide to water, can also be used. In such a case, the addition of a peroxidase-mediating compound is preferred, for example an acetosyringone, a phenolic derivative or a phenothiazine or phenoxazine, but also the polymeric color transfer inhibitors mentioned previously may also be used.

Since flat textile structures, especially rayon, fiber (viscose), cotton and their mixtures, may have a tendency to wrinkle, because individual fibers are prone to be oriented transversely with respect to the direction of the fibers, due to Push-ups, bends, compressions and crushing, detergents or cleaning agents may contain synthetic anti-wrinkle agents. These include, for example, synthetic products based on fatty acids, fatty acid esters, fatty acid amides, fatty acid alkyl esters, fatty acid alkylamides or in fatty alcohols, which in general have reacted with ethylene oxide or the products based on lecithin or modified phosphoric acid esters.

To eliminate (control) microorganisms, detergents or cleaning products may contain antimicrobial active substances. Among them it is possible to distinguish according to the antimicrobial spectrum and the mechanism of action between bacteriostatic and bactericidal, fungistatic and fungicidal, etc. The main substances of these groups are, for example, benzalkonium chlorides, alkylarylsulfonates, halogenated phenols and phenol mercuriacetate, although these compounds can be dispensed with even completely.

Detergents or cleaning products may contain preservatives, which will preferably be used only, if they do not have skin sensitizing potential or have very low. Examples of this are sorbic acid and its salts, benzoic acid and its salts, salicylic acid and its salts, phenoxyethanol, formic acid and its salts, 3-iodo-2-propynylbutyl carbamate, N- ( hydroxymethyl) sodium glycinate, biphenyl-2-ol and mixtures thereof. Other suitable preservatives are isothiazolones, mixtures of isothiazolones and mixtures of isothiazolones with other compounds, for example tetramethylolglycoluril.

To avoid annoying alterations of detergents or cleaning products or of flat textile materials treated with them, caused by oxygen and other oxidizing processes, said detergents or cleaning products may contain antioxidants. This group of compounds includes, for example, substituted phenols, hydroquinones, pyrocatechin, aromatic amines, organic sulphides, polysulfides, dithiocarbamates, phosphites, phosphonates and vitamin E.

The additional use of antistatic agents can lead to greater comfort of use, such agents can be added to detergents or cleaning products. The antistatic agents extend the surface conductivity and thus allow a better evacuation of the charges formed. External antistatics are usually substances that have at least one hydrophilic molecular ligand and give rise to a more or less hygroscopic film on the surfaces.

These antistatics, usually surfactants, can be divided into nitrogen antistatics (amines, amides, quaternary ammonium compounds), phosphorous (phosphates) and sulfur (alkylsulfonates, alkylsulfates). The lauryl- (or stearyl-) dimethylbenzylammonium chlorides are suitable as antistatic agents for flat textile structures or as additives for detergents or cleaning agents, in this case a fanning effect is also achieved.

To improve rewetting and to facilitate ironing of the treated flat textile structures, silicone compounds may be incorporated into the detergent or cleaning product, for example. These also improve the rinse behavior of detergents or cleaning products thanks to their foaming inhibitory properties. Preferred silicone derivatives are for example polydialkyl- or alkylarylsiloxanes, whose alkyl groups have one to five C atoms and are totally or partially fluorinated. Preferred silicones are polydimethylsiloxanes, which may eventually be derivatized and, in that case, they may have amino functional groups or they may be quaternized or have Si-OH-, Si-H- and / or Si-Cl bonds. The viscosities of the preferred silicones at 25 ° C are between 100 and 100,000 mPas, said silicones can be used in amounts between 0.2 and 5% by weight, a percentage based on the total weight of the detergent or cleaning product.

Preferred detergents or cleaning products contain a silicone compound. Depending on their derivatization, the silicone compounds used can even give the flat textile structures treated with the detergent or cleaning product a softening effect. Liquid detergents or cleaning products, which carry a silicone compound and the combination of the invention of fatty acid (or fatty acid salt) and (co) polymer of (meth) acrylic acid, are perfectly stable and especially do not have any tendency to precipitation of the silicone compound.

Finally, detergents and cleaning products may contain UV absorbers, which are absorbed in the extensive textile structures treated and improve the light stability of the fibers. The compounds, which have these desired properties, are for example effective for deactivation without radiation and benzophenone derivatives with substituents at position 2 and / or 4. Otherwise, substituted benzotriazoles, phenyl substituted acrylates are also suitable. position 3 (derivatives of cinnamic acid), possibly with cyano groups in position 2, salicylates, organic nickel complexes as well as natural substances of the umbeliferone type and the urocanic acid secreted by the human organism.

To prevent the destruction of certain detergent ingredients, catalyzed by heavy metals, compounds that form complexes with heavy metals can be used. Suitable chelants for heavy metals are for example the alkali metal salts of ethylenediaminetetraacetic acid (EDTA), nitrilotriacetic acid (NTA) or the trisodium salt of methylglycinadiacetic acid (MGDA) as well as alkali metal salts of anionic polyelectrolytes, for example polymaleates and polysulfonates.

A preferred group of chelants are phosphonates, which may be present in preferred detergents and liquid cleaning products in amounts of 0.01 to 2.5% by weight, preferably 0.02 to 2% by weight and especially from 0.03 to 1.5% by weight. Among the preferred compounds are, in particular, organo phosphonates, for example 1-hydroxyethane-1,1-diphosphonic acid (HEDP), aminotri (methylenephosphonic acid) (ATMP), diethylene-triamino-penta (methylene phosphonic) acid (DTPMP or DETPMP) and 2-phosphonobutane-1,2,4-tricarboxylic acid (PBS-AM), which is generally used in the form of its ammonium salts or alkali metal salts. As alternative sequestrants, which can be used in the detergent or cleaning product, mention is made of minodisuccinate (IDS) or N, N’-ethylenediamine disuccinate (EDDS).

Detergents or cleaning products can be used for washing and / or cleaning flat textile structures.

The production of detergents and liquid cleaning products is carried out by the usual methods and procedures already known, for this purpose the components are mixed in a reactor for example, by conveniently depositing first the water, the solvents that may be present and the surfactants. . Then 0.1 to less than 5% by weight of a fatty acid and / or a fatty acid salt are added and the fatty acid fraction saponification is performed between 50 and 60 ° C. Then, between 0.01 and less than 0.5% by weight of a (co) polymer of (meth) -acrylic acid and the other ingredients are added, preferably in portions.
