- bleach activators are N, N, N ', N'-tetraacetylethylenediamine (TAED), l,: - diacetyl-2,4-dioxo-hexahydro-l, 3,5-triazine (DADHT) and acetylated sorbitol-mannitol mixtures (S0RMAN).
- TAED N, N, N ', N'-tetraacetylethylenediamine
- DADHT 3,5-triazine
- S0RMAN acetylated sorbitol-mannitol mixtures
- Suitable as foam inhibitors Soaps of natural or synthetic origin, for example, which have a high proportion of Ci8-C24 ⁇ fatty acids.
- Suitable non-surfactant-like foam inhibitors are, for example, organopolysiloxanes and their mixtures with microfine, optionally silanized silica, and paraffins, waxes, microcrystalline waxes and their mixtures with silanized silica or bistearylethylenediamide. Mixtures of different foam inhibitors are also used with advantages, for example those made of silicones, paraffins or waxes.
- the foam inhibitors, in particular silicone 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.
- Suitable enzymes are those from the class of proteases, lipases, amylases, cellulases or mixtures thereof. Enzymatic active ingredients obtained from bacterial strains or fungi such as Bacillus subtilis, Bacillus licheniformis and Streptomyces griseus are particularly suitable. Proteases of the subtilisin type and in particular proteases which are obtained from Bacillus lentus are preferably used.
- Enzyme mixtures for example of protease and amylase or protease and lipase or protease and cellulase or of cellulase and lipase or of protease, amylase and lipase or protease, lipase and cellulase, but in particular mixtures containing cellulase, are of particular interest.
- Peroxides or oxidases have also proven to be suitable in some cases.
- the enzymes can be adsorbed on carriers and / or embedded in enveloping substances in order to protect them against premature decomposition.
- the proportion of the enzymes, enzyme mixtures or enzyme granules can be, for example, about 0.1 to 5% by weight, preferably 0.1 to about 2% by weight.
- the salts of polyphosphonic acids are suitable as stabilizers, in particular for per compounds and enzymes.
- Graying inhibitors have the task of keeping the dirt detached from the fiber suspended in the liquor and thus preventing graying.
- Water-soluble colloids of mostly organic nature are suitable for this, 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 also suitable for this purpose.
- Soluble starch preparations and starch products other than those mentioned above can also be used, for example degraded starch, aldehyde starches, etc.
- Polyvinylpyrrolidone can also be used.
- cellulose ethers such as carboxymethyl cellulose (sodium salt), methyl cellulose, hydroxyalkyl cellulose and mixed ethers, such as methyl hydroxyethyl cellulose, methyl hydroxypropyl cellulose, methyl carboxymethyl cellulose and mixtures thereof, and also polyvinylpyrrolidone, for example in amounts of 0.1 to 5% by weight , based on the funds used.
- the agents can contain derivatives of diaminostilbenedisulfonic acid or its alkali metal salts. Suitable are e.g. Salts of 4,4'-bis (2-anilino-4-morpholino-l, 3,5-triazinyl-6-amino) stilbene-2,2'-disulfonic acid or similar compounds, instead of morpholino Group carry a diethanolamino group, a methylamino group, an anilino group or a 2-methoxyethylamino group. Brighteners of the substituted diphenylstyryl type may also be present, e.g.
- the finished washing or cleaning agents can be constructed uniformly from extrudates which contain the above-mentioned ingredients including the detergent mixtures, which are also extruded as a component of the premix.
- the extrudates are processed with further ingredients of washing or cleaning agents. This can be such that the washing or cleaning agents are obtained from a mixture of several different granules, of which the extrudates according to the invention have the main form part.
- Bleach activators for example N, N'-tetraacylated diamines such as N, N, N ', N'-tetraacetylethylenediamine, enzyme granules containing enzymes, in particular protease and / or lipase and / or cellulase and / or amylase, with mixtures of 2 or 3 enzymes can be particularly advantageous, and perfume mixed in afterwards.
- the extrudates can also be prepared with further finely divided dry powders before the enzymes and the other constituents are added. Examples of these are zeolite, silicas and salts of fatty acids, for example calcium stearate, bleach activator or mixtures of zeolite with one of the other powders mentioned.
- the foaming behavior for detergents can be positively influenced if the foam inhibitor, for example organopolysiloxanes and their mixtures with microfine, optionally silanized silica, and paraffins, waxes, microcrystalline waxes and their mixtures with silanized silica or bistearylethylenediamide, at least in part is not extruded, but is subsequently mixed with the extrudate. It is also possible that the surface of the extrudate according to the invention is first covered, for example, with zeolite or a mixture containing zeolite and then with a foam inhibitor. Such measures make it possible to further improve the flushing behavior of the extrudates.
- the bulk density of the extrudates produced according to the invention is preferably between 600 and 1200 g / 1, bulk densities between 700 and 1000 g / 1 and in particular between 750 and 950 g / 1 being particularly preferred.
- the water-free detergent mixtures were mixed with other customary detergent ingredients.
- the homogenized mixture was then first extruded in a screw press and then through a perforated disc (diameter of the holes 1.1 mm). The resulting strands were then processed into granular granules.
- the composition of the extrudates can be found in Table 1.
- Mixtures RI and R2 are according to the invention, and mixtures VI to V4 are used for comparison.

- C12 / 14-FA2 Ci2 / i4-fatty alcohol-2E0 adduct
- C 16/18-FA40 Ci6 / i8-fatty alcohol-40E0 adduct
- a premix of the compositions given below was prepared in a continuously operating mixer equipped with a cutter head (chopper) and extruded in accordance with the teaching of the international patent application WO-A-91/02047.
- the finished extrudate was dried, but not worked up any further.
- the bulk density of the extrudates according to the invention and the comparative extrudates was between 750 and 900 g / l.
- the compositions of the extrudates can be found in the following table. The abbreviations mentioned mean:
- the proportion of unsulfated Ci6-C ⁇ 8 fatty alcohol from the sulfopone ⁇ ( R ) was 1.45% by weight and of C12-C14 fatty alcohol from the Texapon LS 35 ( R ) was 0.2% by weight, each based on the mixture of the two alkyl sulfate-containing raw materials.
- Ci2-Ci8 fatty alcohol with 5 E0 and Ci2-Ci4 fatty alcohol 3 E0 in a weight ratio of 4: 1
- a 35% by weight aqueous sodium silicate solution (1: 3.0) was used as the plasticizer and / or lubricant.
- a mixture of 9 parts FAS-M with 1 part FA was first produced in Ml in a Lödige mixer. This was then worked into the premix. The finished extrudates were dried and mixed with TAED and the enzyme.
- Table 3 Compositions of the extrudate R3 according to the invention and of the comparative extrudate V5 (in% by weight)
- the table shows that both the flushing-in behavior and the residue behavior of the extrudates in the hand-washing test are significantly better in the case of the extrudate R3 according to the invention than in the comparative example V5.
