- the amount of these additional builder substances is generally not more than the amount of layered silicates and is preferably less than half these silicates; in particular the amount is between 0.1 and 5% by weight, based on the total agent.
- alkaline salts in particular alkali salts, which not only precipitate or complexly bind calcium ions, but also, as far as possible, bring about a synergistic increase in washing power and have dirt-carrying capacity, should be mentioned as an additional framework substance.
- the water-soluble alkali metal or alkali polyphosphates especially pentasodium triphosphate, are still of importance.
- Organic builder substances include sequestering agents of the aminopolycarboxylic acid type, such as, for example. Nitrilotriacetic acid, ethylenediaminetetraacetic acid, and higher homologues.
- Suitable phosphorus-containing organic complexing agents are the water-soluble salts of alkane polyphosphonic acids, amino and hydroxyalkane polyphosphonic acids and phosphonopolycarboxylic acids, such as. B. the compounds methanediphosphonic acid, dimethylaminomethane-1,1-diphosphonic acid, aminotrimethylenephosphonic acid, ethylenediaminetetramethylenephosphonic acid, diethylenetriaminepentamethylenephosphonic acid, 1-hydroxyethane-1,1-diphosphonic acid, 2-phosphonobutane-1,2,4-tricarboxylic acid. These sequestering agents can also be present in smaller amounts as stabilizers for per-compounds.
- the N- and P-free polycarboxylic acids that form complex salts with calcium ions are of particular importance.
- these include low molecular weight compounds, such as. As citric acid, 2,2'-oxydisuccinic acid or carboxymethyloxy succinic acid, and polymeric polycarboxylic acids with a molecular weight of 350 to about 1,500,000 in the form of the water-soluble salts.
- Particularly preferred polymeric polycarboxylates have a molecular weight in the range from 500 to 175,000, and in particular in the range from 10,000 to 100,000. These include compounds such as, for. B.
- polyacrylic acid poly-alphahydoxyacrylic acid and polymaleic acid
- copolymers of the corresponding monomeric carboxylic acids with one another for example from acrylic acid and maleic acid, or with other ethylenically unsaturated compounds, such as. B. with vinyl methyl ether.
- water-soluble salts of polyglyoxylic acid should also be mentioned.
- Particularly suitable water-insoluble inorganic builders are the finely divided synthetic zeolite A-type sodium aluminosilicates containing bound water described in German patent application DE 24 12 837 as phosphate substitutes for detergents and cleaning agents.
- the cation-exchanging sodium aluminosilicates are used in the usual hydrated, finely crystalline form, i.e. H. they have practically no particles larger than 30 »m and preferably consist at least 80% of particles smaller than 10» m.
- Their calcium binding capacity which is determined according to the information in DE 24 12 837, is in the range from 100 to 200 mg CaO / g.
- the zeolite NaA can be used in particular, also the zeolite NaX and mixtures of NaA and NaX.
- the zeolites are preferably only used in the agents according to the invention if no inorganic peroxides, in particular perborate, are present.
- Suitable inorganic, non-complexing salts are the bicarbonates, also known as "washing alkalis", carbonates, borates, sulfates or amorphous silicates of the alkalis.
- Other structural substances that are also used because of their hydrotropic properties are the salts of the non-capillary-active sulfonic acids containing 2 to 9 carbon atoms, carboxylic acids and sulfocarboxylic acids, for example the alkali salts of alkanoic, benzene, toluene, xylene or cumene sulfonic acids, of sulfobenzoic acids, sulfophthalic acid, sulfoacetic acid, sulfosuccinic acid and the salts of acetic acid or lactic acid.
- foam regulators are the salts of fatty acids with 20 to 24 carbon atoms or long-chain N-alkylaminotriazines with essentially 8 to 18 carbon atoms in the alkyl radical or aliphatic C18-C40 ketones.
- Paraffin and silicone oil dispersions are preferred, which can optionally be made up with microfine silica.
- the content can be, for example in the case of soaps, up to 5% by weight of the total composition, in the case of the paraffins and silicone oils it is usually much less, for example 0.05 to 0.5% by weight.
- Graying inhibitors include, above all, cellulose ethers, such as carboxymethyl cellulose, methyl cellulose, hydroxyalkyl celluloses and mixed ethers, such as Mention should be made of methylhydroxyethyl cellulose, methyl hydroxypropyl cellulose and methyl carboxymethyl cellulose, furthermore mixtures of various cellulose ethers, in particular mixtures of carboxymethyl cellulose and methyl cellulose.
- cellulose ethers such as carboxymethyl cellulose, methyl cellulose, hydroxyalkyl celluloses and mixed ethers, such as Mention should be made of methylhydroxyethyl cellulose, methyl hydroxypropyl cellulose and methyl carboxymethyl cellulose, furthermore mixtures of various cellulose ethers, in particular mixtures of carboxymethyl cellulose and methyl cellulose.
- bleach activators in addition to inorganic peroxide.
- These are acylating agents which react with hydrogen peroxide in the wash liquor to form peroxycarboxylic acids or their salts.
- Examples of common bleach activators are tetraacetylethylenediamine, pentaacetylglucose and diacetyldioxohexahydrotriazine.
- anhydrides can also be used.
- Bleach activators are preferably used which remain largely undissolved in the liquid portion of the detergent and are therefore predominantly in suspended form.
- the amounts of bleach activators are preferably not more than 6% by weight, in particular between 2 and 5% by weight, based on the total agent.
- Optical brighteners which are particularly suitable for detergents are alkali salts of 4,4-bis (2 '' - anilino-4 '' - morpholino-1,3,5-triazinyl-6 '' - amino) stilbene-2,2'-disulfonic acid or compounds of the same structure which carry a diethanolamino group instead of the morpholino group. Furthermore, brighteners of the type of the substituted diphenylstyryl come into question, e.g. B.
- Detergent boosters are polar long-chain compounds that do not themselves have any surface-active properties, but are able to increase the cleaning effect of the surfactants contained in the detergents. Examples of such compounds are coconut amine + 2 EO and the addition products of glycerol and long-chain ⁇ -olefin epoxide.
- Enzymes from the class of proteases, lipases and amylases or their mixtures are possible.
- Bacterial strains or fungi such as Bacillus subtilis, Bacillus licheniformis and are particularly suitable Streptomyces griseus enzymatic substances obtained.
- the enzymes can be embedded in coating substances to protect them against premature decomposition.
- the preparation of the agents according to the invention presents no difficulties.
- it is carried out by mixing all the components, the components which later form the liquid phase are advantageously first premixed and then the components to be suspended are introduced into this liquid and mixed homogeneously therewith.
- the solid constituents of the composition are preferably already based on particle sizes as they are later to be present in the finished composition, but it is also possible to further reduce the size of the suspended solid particles by wet grinding the finished composition.
- the viscosity of the finished product depends primarily on the solid / liquid ratio in the finished product and on the viscosity of the liquid phase. This in turn can be varied within wide limits by choosing suitable components.
- the viscosity can be reduced by adding organic solvents and the viscosity can be increased by adding constituents with a thickening effect, such as soaps.
- Liquid agents according to the invention preferably have viscosities between about 1,000 and about 5,000 mPas, in particular between about 2,000 and about 4,000 mPas, the viscosity being measured using a Brookfield viscometer at 20 ° C.
- the viscosities of the detergent in paste form which are preferred because of their particularly high physical stability, go far beyond.
- the agents according to the invention are primarily intended for use in textile washing. Depending on the content of active ingredients, they can be used as stand-alone detergents or as detergent additives. However, if the active ingredients are selected appropriately, they are also suitable for cleaning hard surfaces in the home or in the commercial sector. Due to the stability of the suspensions, the agents can also be dosed automatically.
- the paste-like detergents A and B described below were prepared in batches of 50 g each by weighing all the components together and homogenizing the mixtures in a ceramic ball mill (running time 5 minutes).
- ingredients Percentage by weight A B Crystalline layered disilicate (delta form) (SKS 6, Hoechst AG) 19.1 21.1 Nonionic surfactant Dehydol LST 80/20 (Henkel) 10.5 18.0 Polyethylene glycol 400 5.3 5.4 C 12/13 alkylbenzenesulfonate Na (55% aqueous paste) 33.3 14.5 Sodium perborate tetrahydrate 31.8 22.0 sodium - 9.0
