Definitions
- the invention is in the field of detergents and cleaning agents. It affects the production and use of solid, water-soluble alkali metal silicates, optionally as a compound with other components containing such Amount of nonionic surfactants are loaded that the weight ratio non-ionic surfactants for solid product serving as carrier is greater than 0.5. In spite of this high loading with the liquid or waxy nonionic This compound is flowable to tensides and can therefore be more solid as a component Detergents, washing aids and cleaning agents are used.
- the water soluble Alkali metal silicate has a double function: it serves as a Backing material for absorbing liquid to waxy nonionic Surfactants. Secondly, it itself has builder and anti-corrosion properties and thus contributes to the performance of detergents and cleaning agents.
- Nonionic surfactants are an essential component of current laundry and Detergent.
- suitable carrier material For this you use usually inorganic carrier materials, but only up to one certain maximum limit can be loaded with the nonionic surfactants, without getting sticky.
- carrier materials for example, as in Known in the art, sodium carbonate or sodium sulfate can be if necessary, produce compounds that contain up to 30% by weight of nonionic surfactants contain.
- pore-rich carrier materials such as water-insoluble silicates and aluminosilicates such as, in particular, zeolites can be Compounds containing up to 65 wt .-% nonionic surfactants.
- the carrier materials mentioned have the disadvantage of not being water-soluble be.
- WO 97/28240 provides a dispersion, its continuous phase is a concentrated aqueous solution of an alkali metal silicate in which Droplets or particles of the nonionic surfactants are dispersed.
- This Dispersion can be dried in the form of a thin film, for example, which you can then break up into a powder. This gives you a free-flowing powder from sodium silicates, in the particles of which are droplets nonionic surfactants are included.
- the content of the compound nonionic surfactants can be over 50% by weight, i. H. the Weight ratio of nonionic surfactants to alkali metal silicates can be greater than 1 be.

- the compound is said to flow freely and as a component of solid washing and Detergent can be used.
- Alkali metal silicates in the specified ranges of the molar ratio have builder properties in detergents and cleaning agents, combined with an anti-corrosion effect.
- alkali metal silicates which contain only sodium as alkali metal.
- Potassium silicates are more expensive than Sodium silicates, but more soluble in water. So you put on a particularly high one Water solubility value, it is recommended that the sodium at least partially to be replaced by potassium.
- the aqueous solution containing the alkali metal silicates can to any solid product known in the art be dried.
- the drying takes place so far that the obtained Solids still have a residual water content by measuring the weight loss is determinable at 800 ° C, in the range of about 3 to about 25 wt .-%.
- the Drying to a solid product can, for example, in an oven, with a Contact dryers, in a fluidized bed or by spray drying.
- the preferred drying method is spray drying.
- the spray drying process is widely used in the prior art. For example, it is extensively described in K. Masters: Spray Drying Handbook ", 4th edition, George Godwin, London (1985). The drying conditions for sodium silicate solutions are discussed in more detail on pages 566 and 567 thereof. Furthermore, spray drying of alkali metal silicate solutions is described, for example, in US Pat. No. 3,8398,192.
- the aqueous solution which contains the alkali metal silicates and which is dried to a solid product in sub-step a), can contain and / or disperse further ingredients of washing, washing aids and cleaning agents in such an amount that the proportion of alkali metal silicates in the total solids content the aqueous solution is between 99.9 and 50% by weight.

- the sub-step of pulverization can therefore for example omitted if the solid product by spray or Fluid bed drying was obtained. It is then already in the desired one Powder form.
- step a) the aqueous solution is closed in a way a solid product has been dried so that it is not in powder form, so it has to be ground to a powder. This is the case, for example, if you use oven or contact drying.
- the powder becomes the fraction isolated with a particle size in the range of 0.2 to 0.6 mm, provided that The powder was not produced in such a way that it was at least 90 % By weight consists of this fraction. For example, it is after a spray or Fluid bed drying required, from the powder obtained the above Isolate fraction.

Mixtures of various foam inhibitors are also used with advantages, for example those made of silicones, paraffins or waxes.
- the foam inhibitors, in particular silicone and / or paraffin-containing foam inhibitors are preferably bound to a granular, water-soluble or dispersible carrier substance. Mixtures of paraffins and bistearylethylenediamides are particularly preferred.
- Enzymes come from the class of proteases, lipases, amylases, Cellulases or their mixtures in question.
- Bacterial strains are particularly suitable or mushrooms, such as Bacillus subtilis, Bacillus licheniformis, Streptomyces griseus and Humicola insolens enzymatic active ingredients obtained.
- Proteases of the subtilisin type and in particular proteases are preferably which are obtained from Bacillus lentus.
- enzyme mixtures for example from protease and amylase or protease and lipase or Protease and cellulase or from cellulase and lipase or from protease, amylase and lipase or protease, lipase and cellulase, but especially protease and / or Mixtures of lipase of particular interest.
- Peroxidases too or oxidases have been found to be suitable in some cases.
- the enzymes can be adsorbed on carriers and / or embedded in coating substances in order to protect them against premature decomposition.
- the proportion of enzymes, enzyme mixtures or enzyme granules can, for example, about 0.1 to 5% by weight, preferably 0.1 to about 2% by weight.
- the salts come as stabilizers, in particular for per-compounds and enzymes of polyphosphonic acids, especially 1-hydroxyethane-1,1-diphosphonic acid (HEDP), diethylenetriaminepentamethylenephosphonic acid (DETPMP) or Ethylenediaminetetramethylenephosphonic acid into consideration.
- HEDP 1-hydroxyethane-1,1-diphosphonic acid

- Ethylenediaminetetramethylenephosphonic acid into consideration.
- the agents can also contain further enzyme stabilizers.
- enzyme stabilizers For example, 0.5 to 1% by weight sodium formate can be used. It is also possible to use proteases which are stabilized with soluble calcium salts and a calcium content of preferably about 1.2% by weight, based on the enzyme.
- boron compounds for example boric acid, boron oxide, borax and other alkali metal borates such as the salts of orthoboric acid (H 3 BO 3 ), metaboric acid (HBO 2 ) and pyrobic acid (tetraboric acid H 2 B 4 O 7 ), is particularly advantageous.
- Graying inhibitors have the task of removing the dirt detached from the fiber keep suspended in the fleet and thus prevent graying.
- water-soluble colloids mostly of an organic nature, for example the water soluble salts of polymeric carboxylic acids, glue, gelatin, salts of Ether carboxylic acids or ether sulfonic acids of starch or cellulose or salts of acidic sulfuric acid esters of cellulose or starch.
- water soluble, polyamides containing acidic groups are suitable for this purpose.
- Polyvinyl pyrrolidone is useful.
- cellulose ethers such as Carboxymethyl cellulose (Na salt), methyl cellulose, hydroxyalkyl cellulose and Mixed ethers, such as methylhydroxyethylcellulose, methylhydroxypropylcellulose, Methyl carboxymethyl cellulose and mixtures thereof, and polyvinyl pyrrolidone for example in amounts of 0.1 to 5 wt .-%, based on the agent used.
- the agents can, as optical brighteners, derivatives of diaminostilbenedisulfonic acid or their alkali metal salts. Suitable are e.g. 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 instead of the morpholino group Diethanolamino group, a methylamino group, an anilino group or a 2-methoxyethylamino group carry. Brighteners of the type of substituted diphenylstyryl, e.g.
- the invention further relates to a method for producing a washing, Detergent or cleaning agent, in which one after the Powdered mixture produced according to the method of the invention Alkali metal silicates and non-ionic surfactants with the remaining ingredients of the detergent, auxiliary washing agent or cleaning agent. Examples of such remaining ingredients were listed above.
- the washing manufactured by mixing the components mentioned Detergents or cleaning agents can be used in the prior art known measures such as granulation, compacting or Extrusion can be brought into a low-dust form and / or compressed. To this way, compact detergents with bulk weights can be obtained for example in the range from 500 to 1000 g / l.
- the invention relates to solid washing, auxiliary washing or cleaning agents, which is a powdery prepared by the inventive method Contain a mixture of alkali metal silicates and nonionic surfactants.
- auxiliary washing or Detergent is in the amount range between about 5 and about 50 wt .-%. The remainder to 100 wt .-% form those listed above by way of example remaining components of washing, washing aids or cleaning agents.
- the surfactant absorption capacity was analogous to the standard DIN ISO 787 General test methods for pigments and fillers, determination of the oil number "in the version from 1983, wherein the coating oil was replaced by nonionic surfactant (C 12-18 fatty alcohol x 7 mol ethylene oxide).
- the determination is made as follows: The sample is placed on a glass plate (in the case of the glass balls, a watch glass is used) and weighed out. 4 to 5 drops of nonionic surfactant (C 12-18 fatty alcohol x 7 mol ethylene oxide) are slowly added from a Pasteur pipette. After the addition, the surfactant is worked into the sample with a spatula. The addition of the surfactant continues accordingly until the agglomeration of surfactant and sample forms. Then a drop of surfactant is added and rubbed in thoroughly with a spatula until a soft paste suddenly forms. The paste should stick to the plate without tearing or crumbling. The amount of surfactant absorbed is determined by weighing again.
- nonionic surfactant C 12-18 fatty alcohol x 7 mol ethylene oxide
