Description

Field of the invention

The invention relates to solid compositions containing hydroxy mixed ethers and optionally other surfactants, polymers and inorganic or organic carriers, a process for their preparation and the use of solid agents as a precompound for the production of detergents, dishwashing detergents and cleaning agents.

State of the art

On machine-washed dishes today high demands are made. Thus, even a completely cleaned of leftovers utensils is then rated as not flawless if it still has whitish, based on water hardness or other mineral salts stains that are due to the lack of wetting agent from dried water droplets after machine dishwashing. To obtain glossy and spotless dishes, you therefore use rinse aid. The addition of liquid or solid rinse aid, which can be added separately or already in ready-to-use form with the detergent and / or regenerating salt together ("2 in 1", "3 in 1", eg in the form of tablets or powders), provides ensure that the water runs as completely as possible from the items to be washed, so that the different surfaces at the end of the washing program are residue-free and shiny.

Commercially available rinse aids are mixtures of, for example, nonionic surfactants, solubilizers, organic acids and solvents, water and optionally preservatives and fragrances. The object of the surfactants in these compositions is to influence the interfacial tension of the water so that it is in as thin as possible continuous film Run off the dishes, so that during the subsequent drying process no drops of water, streaks or films remain (so-called network effect). For this reason, surfactants in rinse aids must also damp the foam in the dishwasher caused by food particles. Since the rinse aid usually contain acids for improving the Klartrocknungseffekt, the surfactants used must additionally be comparatively hydrolysis insensitive to acids.

Rinse aids are used both in the household and in the commercial sector. In Haushaltsgeschirrspülem the rinse aid is usually added after the pre-rinsing and cleaning process at about 40 to 65 ° C. The commercial dishwashers work with only one cleaning liquor, which is renewed only by adding the rinse solution from the previous rinse. So there is no complete water exchange during the entire wash program. Therefore, the rinse aid must also foam-suppressing, be stable even at a strong temperature gradient of about 85 to about 35 ° C and prove to be inert to alkali and active chlorine compounds.

In this connection, please refer to the German Offenlegungsschrift DE 19738866 A1 (Cognis ), are known from the surfactant mixtures containing nonionic surfactants of the type of hydroxy mixed ethers and fatty alcohol polyglycol ethers, which have a good foaming behavior and show good results in rinse aids.

From the DE 199 62 885 A1 detergent tablets are known which contain hydroxy mixed ethers, a polymer and other solids. The WO 00/27903 A1 describes solid detergents which, in addition to hydroxy mixed ethers, may contain further surfactants, polymers and carriers. From the WO 01/79401 A1 Surfactant granules are known which may contain 40% by weight of hydroxy mixed ether, 50% by weight of cellulose as carrier and 5% by weight of polycarboxylates. In the WO 00/42152 A1 For example, solid detergents and cleaners are disclosed which, in addition to hydroxy mixed ethers, may contain polymers and carriers. Finally, that describes US 5,967,157 A1 automatic dishwashing detergents which may contain hydroxy mixed ethers in combination with polymers and co-polymers of acrylic acid.

The object of the present invention has consisted of surfactants in solid form (solid) for the preparation of solid detergents, dishwashing detergents and cleaners, in particular solid dishwashing detergents, for example the so-called "2 in 1" or "3 in 1" dishwashing detergent , to provide.

The solid agents should be characterized in that they have excellent Klarspüleigenschaften, even in the presence of protein soilings foam-suppressing, are stable even at high temperature gradient, do not gel during dissolution and in particular have a solubility kinetics, the carryover of the highest possible content of nonionic surfactant into the rinse of the machine process also made possible to produce simpler solid detergent formulations. Furthermore, the surfaces to be cleaned or rinsed should be equipped in such a way that it is easier to remove soiling during the next cleaning process.

The object was achieved by the provision of solid agents which contain a combination of hydroxy mixed ethers and polymers in the mixing ratio according to the invention,
be solved. By providing these solid agents, for example as a precompound in washing, rinsing and cleaning agent formulations, the surfactant content, in particular the content of hydroxy mixed ether, can be reduced while the cleaning power remains consistently high.
Nevertheless, this results in a very good wetting ability and a spotless gloss of the surfaces to be cleaned. The addition of polymers to rinse aids means that at the next cleaning otherwise strongly adhering and often critical stains such as starchy stains, can be completely removed. These soiling can be removed without additional manual processing of the items to be washed.

➢ zeolites

Among the zeolites, the detergency builders zeolite A and / or P are particularly preferred. As zeolite P, for example, zeolite MAP ^(R) (commercial product from Crosfield) is particularly preferred. Also suitable, however, are zeolite X and mixtures of A, X and / or P as well

Y. Of particular interest is a co-crystallized sodium / potassium aluminum silicate of zeolite A and zeolite X, which as VEGOBOND AX ^® (commercial product from Condea Augusta SpA) is commercially available. The zeolite can be used as a spray-dried powder or else as undried, still moist, stabilized suspension of its preparation. In the event that the zeolite is used as a suspension, these may contain small additions of nonionic surfactants as stabilizers, for example 1 to 3 wt .-%, based on zeolite, of ethoxylated C ₁₂ -C ₁₈ fatty alcohols having 2 to 5 ethylene oxide groups , C ₁₂ -C ₁₄ fatty alcohols having 4 to 5 ethylene oxide groups or ethoxylated isotridecanols. Suitable zeolites have an average particle size of less than 10 μm (volume distribution;

Coulter Counter) and preferably contain 18 to 22 wt .-%, in particular 20 to 22 wt .-% of bound water.

➢ Alkaline phosphates

In addition to the zeolites, the use of the generally known phosphates as carriers is possible in particular. Particularly suitable are the sodium salts of orthophosphates, pyrophosphates and in particular tripolyphosphates.

➢ alkali silicates

Under alkali silicates crystalline, layered alkali and especially sodium silicates of the general formula NaMSi _x O _{2x + 1} · yH ₂ O to understand, where M is sodium or hydrogen, x is a number from 1.9 to 4 and y is a number from 0 to 20 is and preferred values for x are 2, 3 or 4. Such crystalline layered silicates are described, for example, in the European patent application EP 0164514 A1 described. Preferred crystalline layered silicates of the formula given are those in which M is sodium and x assumes the values 2 or 3. In particular, both β- and δ-sodium disilicates Na ₂ Si ₂ O ₅ .yH ₂ O are preferred, wherein β-sodium disilicate can be obtained, for example, by the method described in International Patent Application WO 91/08171 is described. Further suitable phyllosilicates are, for example, from the patent applications DE 2334899 A1 . EP 0026529 A1 and DE 3526405 A1 known. Its usability is not limited to any particular composition or structural formula. However, smectites, in particular bentonites, are preferred here. Suitable layered silicates which belong to the group of water-swellable smectites are, for example, those of the general formulas (OH) ₄ Si _8-y Al _y (Mg _x Al _4-x ) O ₂₀ montmorillonite (OH) ₄ Si _8-y Al _y (Mg _6-z Li _z ) O ₂₀ hectorite (OH) ₄ Si _8-y Al _y (Mg _6-z Al _z ) O ₂₀ saponite with x = 0 to 4, y = 0 to 2, z = 0 to 6. In addition, small amounts of iron may be incorporated in the crystal lattice of the layered silicates according to the above formulas. Furthermore, the phyllosilicates may contain hydrogen, alkali, alkaline earth metal ions, in particular Na ⁺ and Ca ²⁺ , due to their ion-exchanging properties. The amount of water of hydration is usually in the range of 8 to 20 wt .-% and is dependent on the swelling state or on the type of processing. Useful phyllosilicates are for example US 3,966,629 . U.S. 4,062,647 . EP 0026529 A1 and EP 0028432 A1 known. Preferably, phyllosilicates are used, which are largely free of calcium ions and strong coloring iron ions due to an alkali treatment. The preferred inorganic carrier substances also include amorphous sodium silicates having a modulus of Na ₂ O: SiO _{2 of} from 1: 2 to 1: 3.3, preferably from 1: 2 to 1: 2.8, and in particular of 1: 2 to 1: 2.6, which are delay-delayed and have secondary washing properties. The dissolution delay over conventional amorphous sodium silicates may have been caused in various ways, for example by surface treatment, compounding, compaction nebulization or by overdrying. In the context of this invention, the term "amorphous" is also understood to mean "X-ray amorphous". This means that in X-ray diffraction experiments the silicates do not give sharp X-ray reflections typical of crystalline substances, but at most one or more maxima of the scattered X-rays which are several angstroms in width of the diffraction angle. However, it may even lead to particularly good performance properties if the silicate particles provide blurred or even sharp diffraction maxima in electron diffraction experiments. This is to be interpreted as meaning that the products have microcrystalline regions of size 10 to a few hundred nm, with values of up to max. 50 nm and in particular up to max. 20 nm are preferred. Such so-called X-ray amorphous silicates, which likewise have a dissolution delay compared with the conventional water glasses, are described, for example, in the German patent application DE 4400024 A1 described. Especially preferred are densified / compacted amorphous silicates, compounded amorphous silicates and overdried X-ray amorphous silicates.

Examples of polysaccharides are cellulose, carboxymethylcellulose, cyclodextrin or starch and their degradation products, as polymeric supports (d) are in particular polyacrylates having molecular weights in the range of 1,000 to 50,000 in question.

In terms of content, a distinction is made between the polymers (b) and other polymers used as the carrier (d) and also polymers as auxiliaries and additives (c). In the calculation of weight proportions or proportions is to be distinguished here.

In addition to the hydroxy mixed ethers, the polymers and the carriers, the solid compositions may contain other auxiliary substances and additives typical of detergents, dishwashing detergents and cleaning agents, as well as other surfactants.
In addition to the carriers, which can also perform a function as builders, these are, for example, low-foaming, preferably nonionic cosurfactants, anionic cosurfactants, co-builders, oil and grease solvents, bleaches, bleach activators, grayness inhibitors, enzymes, enzyme stabilizers, optical Brighteners, defoamers, disintegrants, fragrances, inorganic salts and the like, as they are explained in more detail below.

The ethers may be asymmetric or symmetric, i. contain two identical or different alkyl chains, preferably having 8 to 18 carbon atoms. Typical examples are di-n-octyl ether, di-octyl ether and di-n-stearyl ether, particularly suitable are dialkyl ethers having a melting point above 25 ° C, in particular above 40 ° C.

Further suitable defoamer compounds are fatty ketones, which can be obtained by the relevant methods of preparative organic chemistry. For their preparation, one starts, for example, from carboxylic acid magnesium salts, which are pyrolyzed at temperatures above 300 ° C with elimination of carbon dioxide and water, for example according to the German Offenlegungsschrift DE 2553900 OS. Suitable fatty ketones are those prepared by pyrolysis of the magnesium salts of lauric, myristic, palmitic, palmitoleic, stearic, oleic, elaidic, petroselic, arachidic, gadoleic, behenic or erucic acid.

Further suitable defoamers are fatty acid polyethylene glycol esters, which are preferably obtained by basic homogeneously catalyzed addition of ethylene oxide to fatty acids. In particular, the addition of ethylene oxide to the fatty acids takes place in the presence of alkanolamines as catalysts. The use of alkanolamines, especially triethanolamine, results in extremely selective ethoxylation of the fatty acids, especially when it comes to producing low ethoxylated compounds. Within the group of fatty acid polyethylene glycol esters, preference is given to those which have a melting point above 25 ° C., in particular above 40 ° C.

Within the group of waxy defoamers, the paraffin waxes described are particularly preferably used alone as waxy defoamers or in mixtures with one of the other waxy defoamers, wherein the proportion of paraffin waxes in the mixture is preferably more than 50% by weight, based on waxy defoamer mixture. The paraffin waxes can be applied to carriers as needed. As carrier material, all known inorganic and / or organic carrier materials are suitable. Examples of typical inorganic carrier materials are alkali metal carbonates, aluminosilicates, water-soluble phyllosilicates, alkali metal silicates, alkali metal sulphates, for example sodium sulphate, and alkali metal phosphates. The alkali metal silicates are preferably a compound having a molar ratio of alkali metal oxide to SiO _{2 of} from 1: 1.5 to 1: 3.5. The use of such silicates results in particularly good Komeigenschaften, in particular high abrasion stability and yet high dissolution rate in water. The aluminosilicates referred to as support material include, in particular, the zeolites, for example zeolite NaA and NaX. The compounds referred to as water-soluble layered silicates include, for example, amorphous or crystalline water glass. Furthermore, silicates can be used, which are under the name Aerosil® or Sipernat® commercially. Suitable organic support materials are, for example, film-forming polymers, for example polyvinyl alcohols, polyvinylpyrrolidones, poly (meth) acrylates, polycarboxylates, cellulose derivatives and starch. Useful cellulose ethers are, in particular, alkali metal carboxymethylcellulose, methylcellulose, ethylcellulose, hydroxyethylcellulose and so-called cellulose mixed ethers, such as, for example, methylhydroxyethylcellulose and methylhydroxypropylcellulose, and mixtures thereof. Particularly suitable mixtures are composed of sodium carboxymethylcellulose and methylcellulose, wherein the carboxymethylcellulose usually has a degree of substitution of 0.5 to 0.8 carboxymethyl groups per anhydroglucose unit and the methylcellulose has a degree of substitution of 1.2 to 2 methyl groups per anhydroglucose unit. The mixtures preferably contain alkali metal carboxymethylcellulose and nonionic cellulose ethers in weight ratios of from 80:20 to 40:60, in particular from 75:25 to 50:50. Native starch composed of amylose and amylopectin is also suitable as the carrier. Native starch is starch, as it is available as an extract from natural sources, such as rice, potatoes, corn and wheat. Native starch is a commercial product and thus easily accessible. As carrier materials, one or more of the abovementioned compounds can be used, in particular selected from the group of alkali metal carbonates, alkali metal sulphates, alkali metal phosphates, zeolites, water-soluble phyllosilicates, alkali silicates, polycarboxylates, cellulose ethers, polyacrylate / polymethacrylate and starch. Particularly suitable are mixtures of alkali metal carbonates, in particular sodium carbonate, alkali metal silicates, in particular sodium silicate, alkali metal sulphates, in particular sodium sulphate and zeolites.

Suitable silicones are customary organopolysiloxanes which may have a finely divided silica content, which in turn may also be silanated. Such organopolysiloxanes are for example in the European patent application EP 0496510 A1 described. Particularly preferred are polydiorganosiloxanes and especially polydimethylsiloxanes known in the art. Suitable polydiorganosiloxanes have a nearly linear chain and have a degree of oligomerization of 40 to 1500. Examples of suitable substituents are methyl, ethyl, propyl, isobutyl, tert. Butyl and phenyl. Also suitable are amino-, fatty acid-, alcohol-, polyether-, epoxy-, fluoro-, glycoside- and / or alkyl-modified silicone compounds which may be both liquid and resinous at room temperature. Also suitable are simethicones, which are mixtures of dimethicones having an average chain length of from 200 to 300 dimethylsiloxane units and hydrogenated silicates. In general, the silicones in general and the polydiorganosiloxanes in particular contain finely divided silica, which may also be silanated. Especially suitable for the purposes of the present invention are siliceous dimethyl polysiloxanes. Advantageously, the polydiorganosiloxanes have a Brookfield viscosity at 25 ° C (spindle 1, 10 rpm) in the range from 5000 mPas to 30,000 mPas, in particular from 15,000 to 25,000 mPas. Preferably, the silicones are used in the form of their aqueous emulsions. In general, the silicone is added to the initially charged water with stirring. If desired, thickening agents known in the art may be added to increase the viscosity of the aqueous silicone emulsions. These may be inorganic and / or organic in nature, particular preference is given to nonionic cellulose ethers such as methylcellulose, ethylcellulose and mixed ethers such as methylhydoxyethylcellulose, methylhydroxypropylcellulose, methylhydroxybutylcellulose and anionic carboxycellulose types such as the carboxymethylcellulose sodium salt (abbreviation CMC). Particularly suitable thickeners are mixtures of CMC to nonionic cellulose ethers in a weight ratio of 80:20 to 40:60, in particular 75:25 to 60:40. As a rule, and especially when adding the described thickener mixtures, use concentrations of approximately 0.5 to 10, in particular from 2.0 to 6 wt .-% - calculated as a thickener mixture and based on aqueous silicone emulsion. The content of silicones of the type described in the aqueous emulsions is advantageously in the range of 5 to 50 wt .-%, in particular from 20 to 40 wt .-% - calculated as silicones and based on aqueous silicone emulsion. According to a further advantageous embodiment, the aqueous silicone solutions as thickener starch, which is accessible from natural sources, such as rice, potatoes, corn and wheat. The starch is advantageously present in amounts of from 0.1 to 50% by weight, based on the silicone emulsion, and in particular in a mixture with the already described thickener mixtures of sodium carboxymethylcellulose and a nonionic cellulose ether in the quantities already mentioned. For the preparation of the aqueous silicone emulsions, it is expedient to proceed in such a way that the optionally present Pre-thicken the thickener in water before adding the silicones. The incorporation of the silicones is expediently carried out with the aid of effective stirring and mixing devices.

➢ Explosives

The solid agents may further contain disintegrants or disintegrants. These are substances which are added to the shaped bodies in order to accelerate their decomposition upon contact with water. Overviews can be found eg in J. Pharm. 61 (1972 ) Römpp Chemilexikon, 9th Edition, Volume 6, p. 4440 as well as and Voigt "textbook of pharmaceutical technology" (6th edition, 1987, pp. 182-184 ). These substances increase their volume upon ingress of water, whereby on the one hand the intrinsic volume increases (swelling), on the other hand a pressure can be generated by the release of gases which causes the tablet to disintegrate into smaller particles. Well-known disintegration aids are, for example, carbonate / citric acid systems, although other organic acids can also be used. Swelling disintegration aids are, for example, synthetic polymers such as optionally crosslinked polyvinylpyrrolidone (PVP) or natural polymers or modified natural substances such as cellulose and starch and their derivatives, alginates or casein derivatives. Disintegrating agents based on cellulose are used as preferred disintegrating agents in the context of the present invention. Pure cellulose has the formal gross composition (C ₆ H ₁₀ O ₅ ) _n and is formally a β-1,4-polyacetal of cellobiose, which in turn is composed of two molecules of glucose. Suitable celluloses consist of about 500 to 5000 glucose units and therefore have average molecular weights of 50,000 to 500,000. Cellulose-based disintegrating agents which can be used in the context of the present invention are also cellulose derivatives obtainable by polymer-analogous reactions of cellulose. Such chemically modified celluloses include, for example, products of esterifications or etherifications in which hydroxy hydrogen atoms have been substituted. However, celluloses in which the hydroxyl groups have been replaced by functional groups which are not bonded via an oxygen atom can also be used as cellulose derivatives. The group of cellulose derivatives includes, for example, alkali metal celluloses, carboxymethylcellulose (CMC), cellulose esters and ethers, and aminocelluloses. The said cellulose derivatives are preferably not used alone as disintegrating agents based on cellulose, but used in admixture with cellulose. The content of these mixtures of cellulose derivatives is preferably below 50% by weight, particularly preferably below 20% by weight, based on the cellulose-based disintegrating agent. It is particularly preferred to use cellulose-based disintegrating agent which is free of cellulose derivatives. As a further disintegrating agent based on cellulose or as a component of this component, microcrystalline cellulose can be used. This microcrystalline cellulose is obtained by partial hydrolysis of celluloses under conditions which attack and completely dissolve only the amorphous regions (about 30% of the total cellulose mass) of the celluloses, the crystalline regions (ca. 70%) but leave undamaged. Subsequent deaggregation of the microfine celluloses produced by the hydrolysis yields the microcrystalline celluloses which have primary particle sizes of about 5 μm and can be compacted, for example, into granules having an average particle size of 200 μm. The disintegrating agents can be homogeneously distributed macroscopically in the molded body, but microscopically they form zones of increased concentration due to their production. Disintegrating agents which may be present within the meaning of the invention, such as Kollidon, alginic acid and their alkali metal salts, amorphous or partially crystalline layered silicates (bentonites), polyacrylates, polyethylene glycols are, for example, the publications WO 98/40462 (Rettenmaier ) WO 98/55583 and WO 98/55590 (Unilever ) and WO 98/40463 . DE 19709991 and DE 19710254 (Henkel ) refer to. The teaching of these documents is expressly incorporated by reference. The moldings may contain the disintegrants in amounts of 0.1 to 25, preferably 1 to 20 and in particular 5 to 15 wt .-% - based on the moldings.

Fragrances

As perfume oils or fragrances, individual fragrance compounds, e.g. the synthetic products of the ester, ether, aldehyde, ketone, alcohol and hydrocarbon type are used. Fragrance compounds of the ester type are known e.g. Benzyl acetate, phenoxyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinylacetate, phenylethylacetate, linalylbenzoate, benzylformate, ethylmethylphenylglycinate, allylcyclohexylpropionate, styrallylpropionate and benzylsalicylate. The ethers include, for example, benzyl ethyl ether, to the aldehydes e.g. the linear alkanals having 8-18 C atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamen aldehyde, hydroxycitronellal, lilial and bourgeonal, to the ketones e.g. the ionones, α-isomethylionone and methylcedryl ketone, among the alcohols anethole, citronellol, eugenol, geraniol, linalool, phenylethyl alcohol and terpineol, the hydrocarbons mainly include the terpenes such as limonene and pinene. Preferably, however, mixtures of different fragrances are used, which together produce an attractive fragrance. Such perfume oils may also contain natural fragrance mixtures such as are available from vegetable sources, e.g. Pine, Citrus, Jasmine, Patchouly, Rose or Ylang-Ylang oil. Also suitable are muscatel, sage, chamomile, clove, lemon balm, mint, cinnamon, lime, juniper, vetiver, olibanum, galbanum and labdanum, and orange blossom, neroliol, orange peel and sandalwood.

The fragrances can be incorporated directly into the compositions of the invention, but it may also be advantageous to apply the fragrances on carriers, which enhance the adhesion of the perfume on the laundry and provide a slower fragrance release for long-lasting fragrance of the textiles. As such carrier materials, for example, cyclodextrins have proven useful, wherein the cyclodextrin-perfume complexes can additionally be coated with other auxiliaries.

➢ Inorganic salts

Other suitable ingredients of the compositions are water-soluble inorganic salts such as bicarbonates, carbonates, amorphous silicates, normal water glasses which do not have outstanding builder properties, or mixtures of these; In particular, alkali metal carbonate and / or amorphous alkali silicate, especially sodium silicate with a molar ratio of Na ₂ O: SiO ₂ of 1: 1 to 1: 4.5, preferably from 1: 2 to 1: 3.5, are used. The content of sodium carbonate in the final preparations is preferably up to 40 wt .-%, advantageously between 2 and 35 wt .-%. The content of sodium silicate (without any special builder properties) is generally up to 10% by weight and preferably between 1 and 8% by weight. Sodium sulfate in amounts of from 0 to 10, in particular from 1 to 5,% by weight, based on the composition, can furthermore be contained as fillers or leveling agents

The solid compositions according to the invention may, due to their production, have a residual moisture content of not more than 25, preferably not more than 10, and in particular not more than 8 and very particularly preferably less than 5% by weight. Here, the water content of the zeolites is not included.

Preferably, such agents are used which contain 6 to 75, preferably 10 to 40 wt .-% of nonionic surfactants and 25 to 94, preferably 50 to 80 wt .-% of inorganic or organic carriers, with the proviso that the amounts are with the polymers, optionally further surfactants, other auxiliaries and additives and optionally with water and to 100 wt .-% complete.

Surprisingly, it has been found that the hydroxymethylene ether solid compositions according to the invention in combination with polymers on supports fulfill the desired complex profile of requirements to full satisfaction. In particular, it should be noted that these surfactants can be processed with inorganic or organic carriers with little effort to solids that do not gel, but have the desired delayed solubility kinetics. Using the solid agents, for example in the form of granules, it is possible in particular to formulate powders or else tablets with a simultaneous rinse effect. In combination with cleaners or regeneration agents for the ion exchanger, so-called "3 in 1" systems can be realized. In addition to use in the field of machine dishwashing, the solid means can also be used for the conventional cleaning of hard surfaces and for the production of detergents. The invention includes the recognition that the use of the agents according to the invention is not only particularly good Provides clear drying effects, but also provides the best results in terms of foam attenuation, especially in the presence of proteins and temperature stability.

manufacturing

The invention further relates to a process for the preparation of the solid compositions according to the invention as a precompound in detergents, dishwashing detergents and dishwashing detergents, preferably dishwashing detergents, characterized in that hydroxy mixed ethers of the formula (I) and polymers, optionally further surfactants and optionally further auxiliary agents are used. and applying additives to inorganic or organic carriers.

The preparation can be carried out in such a way that there is an intimate mixing of hydroxy mixed ethers, polymers, optionally other surfactants and auxiliaries and additives with carriers.
It is further preferred that only the surface of the support is coated with hydroxy mixed ethers, polymers, optionally further surfactants and auxiliaries and additives.
The agents are preferably prepared by mixing and agglomerating the hydroxy mixed ethers and polymers, and optionally further surfactants and the carriers, as well as optionally the further additives.

The solid agents can be prepared in a preferred embodiment by mixing the components in the ploughshare, Lödige or Eirichmischer.

Preference is furthermore given to their preparation by spray drying or by complex granulation processes, for example fluidized bed granulation, press agglomeration, extrusion, roll compaction, pelleting or tableting.
It is preferred in particular that at least the hydroxymix ether component with the polymers is produced by fluidized bed granulation.

Furthermore, it may be particularly preferred if aqueous preparations of the carrier, for example of the alkali metal silicate or of the alkali metal carbonate, are sprayed together with other remaining components in a drying device, wherein granulation can take place simultaneously with the drying.

➢ Spray drying

In the drying device, in which the aqueous preparation is sprayed, may be any dry equipment. In a preferred process, the drying is carried out as spray drying in a drying tower. The aqueous preparations are exposed in a known manner a drying gas stream in finely divided form. Patent publications by Henkel describe an embodiment of spray drying with superheated steam. The working principle disclosed therein is hereby expressly also made the subject of the present invention disclosure. Reference is made in particular to the following publications: DE 4030688 A1 as well as the further publications according to DE 4204035 A1 ; DE 4204090 A1 ; DE 4206050 A1 ; DE 4206521 A1 ; DE 4206495 A1 ; DE 4208773 A1 ; DE 4209432 A1 and DE 4234376 A1 , This process has already been presented in connection with the production of the defoamer com.

➢ Vertebral layer granulation

A particularly preferred way to prepare the means is to subject the precursors to fluidized bed granulation ("SKET" granulation). This is to be understood as meaning a granulation with simultaneous drying, which preferably takes place batchwise or continuously. The precursors can be used both in the dried state and as an aqueous preparation. Preferably used fluidized bed apparatus have bottom plates with dimensions of 0.4 to 5 m. Preferably, the granulation is carried out at fluidized air velocities in the range of 1 to 8 m / s. The discharge of the granules from the fluidized bed is preferably carried out via a size classification of the granules. The classification can be carried out, for example, by means of a sieve device or by a countercurrent air stream (classifier air), which is regulated in such a way that only particles above a certain particle size are removed from the fluidized bed and smaller particles are retained in the fluidized bed. Usually, the incoming air is composed of the heated or unheated classifier air and the heated bottom air. The soil air temperature is between 80 and 400, preferably 90 and 350 and in particular less than 70 ° C. Advantageously, a starting material, for example a granulate from a previous experimental batch, is initially introduced at the beginning of the granulation.

➢ Press agglomeration

In another preferred variant, especially when agents of high bulk density are to be obtained, the mixtures are subsequently subjected to a compaction step, with further ingredients being added to the compositions only after the compaction step. The compaction of the ingredients takes place in a preferred embodiment of the invention in a press-agglomeration process. The press agglomeration process, to which the solid premix (dried base detergent) is subjected, can be realized in various apparatuses. Depending on the type of agglomerator used, different press agglomeration processes are distinguished. The four most common and in the present invention preferred press agglomeration processes are the extrusion, the roll pressing or compaction, the hole pressing (pelletizing) and tableting, so that in the present invention preferred press agglomeration processes extrusion, Walzenkompaktierungs-, pelletizing or Tabletting operations are.

All methods have in common that the premix is compressed under pressure and plasticized and the individual particles are pressed together while reducing the porosity and adhere to each other. In all processes (in the case of tabletting with restrictions), the tools can be heated to higher temperatures or cooled to dissipate the heat generated by shearing forces.

In all methods, one or more binders can be used as an aid for compaction. However, it should be made clear that it is always possible to use several different binders and mixtures of different binders. In a preferred embodiment of the invention, a binder is used which is completely present as a melt at temperatures up to a maximum of 130 ° C., preferably up to a maximum of 100 ° C. and in particular up to 90 ° C. The binder must therefore be selected depending on the process and process conditions or the process conditions, in particular the process temperature must - if a particular binder is desired - be adapted to the binder.

The actual compression process is preferably carried out at processing temperatures which correspond at least in the compression step at least the temperature of the softening point, if not even the temperature of the melting point of the binder. In a preferred embodiment of the invention, the process temperature is significantly above the melting point or above the temperature at which the binder is present as a melt. Especially However, it is preferred that the process temperature in the compression step is not more than 20 ° C above the melting temperature or the upper limit of the melting range of the binder. Although it is technically quite possible to set even higher temperatures; However, it has been shown that a temperature difference to the melting temperature or to the softening temperature of the binder of 20 ° C in general is quite sufficient and even higher temperatures cause no additional advantages. Therefore, it is particularly preferred, especially for energetic reasons, to work above, but as close as possible to the melting point or at the upper temperature limit of the melting range of the binder. Such a temperature control has the further advantage that even thermally sensitive raw materials, for example peroxy bleaches such as perborate and / or percarbonate, but also enzymes, can increasingly be processed without serious losses of active substance. The possibility of precise temperature control of the binder in particular in the decisive step of the compression, ie between the mixing / homogenization of the premix and the shaping, allows an energetically very favorable and extremely gentle for the temperature-sensitive components of the premix process, since the premix for a short time the is exposed to higher temperatures. In preferred press agglomeration processes, the working tools of the press agglomerator (the screw (s) of the extruder, the roller (s) of the roll compactor and the press roll (s) of the pellet press) have a maximum temperature of 150 ° C., preferably not more than 100 ° C. and in particular not more than 75 ° C and the process temperature is 30 ° C and in particular at most 20 ° C above the melting temperature or the upper temperature limit of the melting range of the binder. Preferably, the duration of the effect of temperature in the compression region of the pressing agglomerators is a maximum of 2 minutes and is in particular in a range between 30 seconds and 1 minute.

Preferred binders which can be used alone or in admixture with other binders are polyethylene glycols, 1,2-polypropylene glycols and modified polyethylene glycols and polypropylene glycols. Particularly preferred are combinations of polyethylene glycols with nonionic surfactants, especially of the fatty alcohol polyglycol ether type. The modified polyalkylene glycols include, in particular, the sulfates and / or the disulfates of polyethylene glycols or polypropylene glycols having a molecular weight between 600 and 12,000 and in particular between 1,000 and 4,000. Another group consists of mono- and / or disuccinates of the polyalkylene glycols in turn, have molecular weights between 600 and 6,000, preferably between 1,000 and 4,000. For a more detailed description of the modified polyalkylene glycol ethers, refer to the disclosure of the international patent application WO 93/02176 directed. For the purposes of this invention, polyethylene glycols include those polymers which, in addition to ethylene glycol, also produce C ₃ -C ₅ glycols and also glycerol and mixtures from these can be used as starting molecules. Also included are ethoxylated derivatives such as trimethylolpropane having 5 to 30 EO. The polyethylene glycols preferably used may have a linear or branched structure, with particular preference being given to linear polyethylene glycols. Particularly preferred polyethylene glycols include those having molecular weights between 2,000 and 12,000, advantageously about 4,000, wherein polyethylene glycols having molecular weights below 3,500 and above 5,000, in particular in combination with polyethylene glycols having a molecular weight of about 4,000 can be used and Such combinations advantageously have more than 50% by weight, based on the total amount of polyethylene glycols, of polyethylene glycols having a molecular weight between 3,500 and 5,000. However, polyethylene glycols which are present in liquid state at room temperature and a pressure of 1 bar can also be used as binders; Here is mainly of polyethylene glycol with a molecular weight of 200, 400 and 600 the speech. However, these liquid per se polyethylene glycols should be used only in a mixture with at least one other binder, said mixture must meet the requirements of the invention again, ie must have a melting point or softening point of at least above 45 ° C. Likewise suitable as binders are low molecular weight polyvinylpyrrolidones and derivatives of these having molecular weights of not more than 30,000. Preference is given here to molecular weight ranges between 3,000 and 30,000, for example around 10,000. Polyvinylpyrrolidones are preferably not used as sole binders but in combination with others. especially in combination with polyethylene glycols used.

The compacted material preferably has temperatures not exceeding 90 ° C. directly after leaving the production apparatus, temperatures between 35 and 85 ° C. being particularly preferred. It has been found that outlet temperatures - especially in the extrusion process - from 40 to 80 ° C, for example up to 70 ° C, are particularly advantageous.

➢ Extrusion

In a further preferred embodiment, the agent according to the invention is produced by means of an extrusion, as used, for example, in US Pat European Patent EP 0486592 B1 or the international patent applications WO 93/02176 and WO 94/09111 respectively. WO 98/12299 to be discribed. In this case, a solid premix is extruded under pressure strand and cut the strand after exiting the hole shape by means of a cutting device to the predeterminable granule dimension. The homogeneous and solid premix contains a plasticizer and / or lubricant which causes the premix to be plastically softened and extrudable under the pressure of specific work. Preferred plasticizing and / or Lubricants are surfactants and / or polymers. To explain the actual extrusion process, reference is hereby expressly made to the abovementioned patents and patent applications. Preferably, the pre-mixture is preferably supplied to a planetary roller extruder or a 2-screw extruder with co-rotating or counter-rotating screw guide, whose housing and its extruder granulating head can be heated to the predetermined extrusion temperature. Under the shearing action of the extruder screws, the premix under pressure, which is preferably at least 25 bar, at extremely high throughputs depending on the apparatus used but also may be below, compacted, plasticized, extruded in the form of fine strands through the hole die plate in the extruder head and finally Preferably, the extrudate is reduced by means of a rotating doctor blade to approximately spherical to cylindrical granules. The hole diameter of the hole nozzle plate and the strand cut length are matched to the selected granule dimension. Thus, the production of granules succeeds a substantially uniformly predictable particle size, wherein in detail the absolute particle sizes can be adapted to the intended use. In general, particle diameters of at most 0.8 cm are preferred. Important embodiments provide for the production of uniform granules in the millimeter range, for example in the range of 0.5 to 5 mm and in particular in the range of about 0.8 to 3 mm. The length / diameter ratio of the chopped primary granules is preferably in the range from about 1: 1 to about 3: 1. It is furthermore preferred to supply the still plastic primary granulate to a further shaping processing step; At the same time, edges present on the raw extrudate are rounded, so that ultimately spherical to approximately spherical extrudate grains can be obtained. If desired, small amounts of dry powder, for example, zeolite powder, such as zeolite NaA powder, may be included in this stage. This shaping can be done in commercially available Rondiergeräten. Care should be taken to ensure that only small amounts of fine grain content are produced in this stage. Drying, which is described in the above-mentioned prior art documents as a preferred embodiment, is subsequently possible, but not absolutely necessary. It may just be preferable to stop drying after the compaction step. Alternatively, extrusions can also be carried out in low-pressure extruders, in the Kahl press (Amandus Kahl) or in the Bexx Bextruder. Preferably, the temperature control in the transition region of the screw, the predistributor and the nozzle plate is designed such that the melting temperature of the binder or the upper limit of the melting range of the binder is at least achieved, but preferably exceeded. The duration of the influence of temperature is in. Compression range of extrusion preferably below 2 minutes and more preferably in a range between 30 seconds and 1 minute.

➢ Roller compaction

The solid preparations according to the invention can also be prepared by means of roll compaction. Here, the premix is selectively metered between two smooth or provided with wells of defined shape rollers and rolled between the two rollers under pressure to form a sheet-like Kompaktat, the so-called scoop. The rollers exert a high line pressure on the premix and can be additionally heated or cooled as required. When using smooth rolls, smooth, unstructured flake tapes are obtained, while by using structured rolls, correspondingly structured flakes can be produced in which, for example, certain shapes of the later detergent particles can be specified. The sling strip is subsequently broken by a tee and crushing process into smaller pieces and can be processed in this way to granules, which can be refined by further known per se surface treatment method, in particular brought into approximately spherical shape. Also in the case of roll compaction, the temperature of the pressing tools, ie the rolls, is preferably not more than 150 ° C., preferably not more than 100 ° C. and in particular not more than 75 ° C. Particularly preferred production processes work in the case of roll compaction with process temperatures which are 10 ° C., in particular at most 5 ° C. above the melting temperature or the upper temperature limit of the melting range of the binder. In this case, it is further preferred that the duration of the action of temperature in the compression region of the smooth rolls or rolls provided with depressions of defined shape amounts to a maximum of 2 minutes and is in particular in a range between 30 seconds and 1 minute.

pelletizing

The agent according to the invention can also be prepared by means of pelleting. Here, the premix is applied to a perforated surface and pressed by means of a pressure-emitting body under plasticization through the holes. In conventional embodiments of pellet presses, the premix is compacted under pressure, plasticized, pressed by means of a rotating roller in the form of fine strands through a perforated surface and finally comminuted with a knock-off device to granules. Here are the most diverse designs of pressure roller and perforated die conceivable. For example, flat perforated plates are used as well as concave or convex ring matrices, through which the material is pressed through one or more pressure rollers. The press rollers may also be conically shaped in the plate devices, in the annular devices can matrices and press roll (s) have co-rotating or opposite sense of rotation. An apparatus suitable for carrying out the method is described, for example, in German Offenlegungsschrift DE 3816842 A1 described.

The ring matrix press disclosed in this document consists of a rotating ring die interspersed by press channels and at least one press roller operatively connected to its inner surface, which presses the material supplied to the die space through the press channels into a material discharge. Here, ring matrix and press roller are driven in the same direction, whereby a reduced shear stress and thus lower temperature increase of the premix can be realized. Of course, it is also possible to work with pelletizing with heatable or coolable rollers in order to set a desired temperature of the premix. Also in the case of pelleting, the temperature of the pressing tools, ie the pressure rollers or press rollers, is preferably not more than 150 ° C., preferably not more than 100 ° C. and in particular not more than 75 ° C. Particularly preferred production processes work in the case of roll compaction with process temperatures which are 10 ° C., in particular at most 5 ° C. above the melting temperature or the upper temperature limit of the melting range of the binder.

➢ tableting

The preparation of the solid preparations according to the invention as shaped articles, preferably those in tablet form, is generally carried out by tabletting or press agglomeration. The resulting particulate press agglomerates can be used either directly as detergents, dishwashing detergents or cleaning agents or aftertreated and / or prepared by conventional methods beforehand. The usual post-treatments include, for example, powdering with finely divided ingredients of detergents or cleaners, whereby the bulk density is generally further increased. However, a preferred aftertreatment is also the procedure according to the German patent applications DE 19524287 A1 and DE 19547457 A1 in which dust-like or at least finely divided ingredients (the so-called fines) are adhered to the particulate finished products according to the invention, which serve as Kem, and thus arise means which have these so-called fines as an outer shell. Advantageously, this is again done by melt agglomeration. For melt agglomeration of the fines on is expressly to the disclosure in the German patent applications DE 19524287 A1 and DE 19547457 A1 directed. In the preferred embodiment of the invention, the solid detergents are in tablet form, these tablets preferably having rounded corners and edges, in particular for storage and transport reasons. The base of these tablets may, for example, be circular or rectangular. Multi-layer tablets, especially tablets with 2 or 3 layers, which may also be different in color, are especially preferred. Blue-white or green-white or blue-green-white tablets are particularly preferred. The tablets can also do this Contain pressed and unpressed portions. Moldings having a particularly advantageous dissolution rate are obtained when the granular constituents before pressing have a proportion of particles which have a diameter outside the range from 0.02 to 6 mm of less than 20, preferably less than 10% by weight. A particle size distribution in the range from 0.05 to 2.0 and particularly preferably from 0.2 to 1.0 mm is preferred.

In a particularly preferred form, aqueous Na-silicate solution, aqueous polymer solution or wax melts and their mixture are sprayed onto the granules produced, and the water is then dried off, thus providing the granules with an outer shell (coating). Both silicate, wax and polymer solution are to be understood and calculated as carrier material.

Industrial Applicability

HME: hydroxy mixed ether, APG: alkyl polyglucoside, FAS: fatty alcohol sulfate, STTP: sodium tripolyphosphate, RT: room temperature

In the following Table 1 , the recipes of automatic dishwashing detergents are reproduced by way of example. Formulation I and II contains the solid compositions according to the invention in the form of a pre-compound and further formulation components. V1 describes a comparison formulation containing the same proportions of hydroxy mixed ether and polymer. However, these were not pre-formulated as fixed funds.

In a mixer various dishwashing powder were prepared. In a dishwasher of the type Miele G661 SC, 25 g of the powders were examined for their Klartrockeneffektes under dirt load and on a scale of (1) = very good to (5) = poorly assessed. The results are summarized in Table 1. <b><u> Table 1 </ u></b> Clear-drying effect % by weight Composition / Performance I II V1 HME ¹⁾ - - 11.9 polymer 0.66 Granules according to Example 4 44 30 - (HME / polymer) (11,910,66) (8,110,45) (11.9 / 0.66) C _12/14 fatty alcohol + 10EO-butyl ether 2 2 2 soda 10 10 10 water glass 9 10 10 sodium tripolyphosphate 14 24 45 Sodium hydrate 10 10 10 sodium sulphate - - 4 enzymes 3 3 3 water ad 100 Clear drying effect 1 2 2 1) C _8/10 fatty alcohol + 1PO + 22EO-2-hydroxydecyl ether

The content of hydroxy mixed ethers (HME) and polymer in Example I and Comparative Example C1 was in each case 11.9 g of HME and 0.66 g of polymer, but in Example II only 8.1 g of HME and 0.45 g of polymer. It can be seen that using the solid compositions according to the invention, even with a lower content of nonionic surfactant and polymer, the same clear-drying effect is achieved, whereas in the case of equal weight. Content of HME and polymer prove to be superior to formulation 1 with the solid agents (44%) according to the invention.
