- the agents can contain derivatives of diaminostilbenedisulfonic acid or their alkali metal salts.
- Suitable are, for example, salts of 4,4'-bis (2-anilino-4-mo ⁇ holino-l, 3,5-triazinyl-6-amino) stilbene-2,2'-disulfonic acid or compounds of the same structure which replace the Mo ⁇ holino Group carry a diethanolamino group, a methylamino group, anilino group or a 2-methoxyethylamino group.
- Brighteners of the substituted diphenylstyryl type may also be present, for example the alkali salts of 4,4'-bis (2-sulfostyryl) diphenyl, 4,4'-bis (4-chloro-3-sulfostyryl) diphenyl, or 4- ( 4- chlorostyryl) -4 '- (2-sulfostyryl) diphenyl. Mixtures of the aforementioned optical brighteners can also be used.
- Suitable foam inhibitors are, for example, soaps of natural or synthetic origin, which have a high proportion of C Ig -C 24 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 bis fatty acid alkyl diamides. Mixtures of different foam inhibitors are also used with advantages, for example those made of silicone, 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.
- the preparation of solid agents according to the invention is not difficult and can be carried out in a known manner, for example by spray drying or granulation, with dextrin, peroxygen compounds and, if appropriate, other thermally sensitive ingredients being added separately later.
- dextrins in particular maltodextrins
- dextrins are usually polysaccharides, in particular starches, broken down by enzymatic means
- their processing in aqueous-alkaline washing Medium ingredient slurries via a spray tower often discolor the spray product, which may be due to typical sugar reactions, such as occur during caramelization. It is therefore preferred to spray-dry a dextrin which is present in a relatively neutral aqueous environment after separation of the enzymatic active ingredients, using the lowest possible temperatures, and to mix the powder obtained in this way with the other detergent ingredients using conventional mixing units.
- Liquid or pasty washing or cleaning agents according to the invention in the form of solutions containing customary solvents are generally produced by simply mixing the ingredients, which can be added in bulk or as a solution to an automatic mixer.
- a basic detergent BW1 containing 15% by weight of a 2: 1 mixture of sodium alkylbenzenesulfonate and sodium fatty alkyl sulfate, 1% by weight of soap, 4% by weight of 5-fold ethoxylated C 12 / ⁇ g alcohol, 25% by weight .-% zeolite Na-A, 6 wt .-% TAED and 100 wt .-% enzyme granules, foam inhibitor granules, water and salts, based on the basic detergent, 5.5 wt .-% dextrinic co-builder (DE approx. 12) and 19 wt .-% sodium percarbonate (Ml) or 16 wt .-% sodium perborate monohydrate (VI).
- the amounts of percarbonate and perborate used result in equal amounts of active oxygen.
- Clean tissue samples were 25 times under the specified conditions of Example 1 with the means Ml, VI or a further comparative composition C2, which was composed as Ml, but instead of the dextrinischen Co-Builders the same amount of polymer of a polycarboxylate (Sokalan ® CP 5) contained, an agent M2 according to the invention, which instead of C 6 oxidized starch according to WO 93/161 10 or an agent M3 according to the invention, which instead contained oxidized starch according to EP 472 042, then dried, weighed and ashed. After cooling, the residue on ignition was weighed out. Table 2 below shows the ash values obtained in this way, expressed as a percentage of the weight. For comparison, the initial value (unwashed fabric) is also given.
- Fabric A WFK test fabric B: bleaching nettle C: terry cloth
- washed tissue samples were weighed out as described above and then boiled out in a 5% EDTA solution with a liquor ratio of 1:20 (textile weight to EDTA solution) and then rinsed thoroughly several times with distilled water. The tissues were dried and weighed again. The difference in weight of the samples before and after treatment, expressed as a percentage of the weight, gives the soluble incrustation.
- Example 1 the reflectance of the test fabric washed 25 times with the respective agent was determined in order to determine the graying of the fabric caused by the washing processes.
- Table 4 shows the measured reflectance values (low values mean high graying) as mean values of duplicate determinations.
- Table 4 Graying [% remission]
- Example 2 To determine the secondary washing capacity, as in Example 2, clean tissue samples from the materials specified there were washed 25 times at 90 ° C. (detergent dosage in each case 80 g; water hardness 23 ° d) in a household washing machine (Miele® W701), dried and incinerated. The ash values obtained in this way, expressed as a percentage of the weight, are given in Table 5 below. For comparison, the initial value AW (unwashed fabric) is also given. Table 5: Ash values [%]
- agents according to the invention have a better secondary washing ability than agents with conventional organic co-builders.
