- bleaching agents are, for example, sodium percarbonate, peroxypyrophosphates, citrate perhydrates and H 2 O 2 -producing peracid salts or peracids, such as perbenzoates, peroxophthalates, diperazelaic acid or diperdodecanedioic acid.
- the bleach content of the detergents is preferably 5 to 25% by weight and in particular 10 to 20% by weight, based in each case on the finished detergent.
- bleach activators can be incorporated into the preparations.
- these are N-acyl or 0-acyl compounds which form organic peracids with H 2 O 2 , preferably N, N'-tetraacylated diamines, p- (alkanoyloxy) benzenesulfonates, furthermore carboxylic anhydrides and esters of polyols such as glucose pentaacetate.
- Other known bleach activators are acetylated mixtures of sorbitol and mannitol, as described, for example, in European patent application EP-A-0 525 239.
- the bleach activators contain bleach activators in the usual range, preferably between 1 and 10% by weight and in particular between 3 and 8% by weight, again each based on the finished detergent.
- Particularly preferred bleach activators are N, N, N ', N'-tetraacetylethylene diamine (TAED), 1,5-diacetyl-2,4-dioxo-hexahydro-1,3,5-triazine (DADHT) and acetylated sorbitol-mannitol mixtures (SORMAN).
- Enzymes come from the class of proteases, lipases or lipolytic acting enzymes, for example cutinases, 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 are preferred Proteases obtained from Bacillus lentus are used.
- Enzyme mixtures for example from protease and amylase or protease and Lipase or lipolytic enzymes or protease and cellulase or from cellulase and lipase or lipolytic enzymes or from protease, Amylase and lipase or lipolytic enzymes or protease, Lipase or lipolytic enzymes and cellulase, in particular however, protease and / or lipase-containing mixtures or mixtures with lipolytic enzymes of particular interest.
- Peroxidases too or oxidases can be used.
- the enzymes can on carriers adsorbed and / or embedded in enveloping substances to protect them against premature To protect decomposition.
- the proportion of enzymes, enzyme mixtures or enzyme granules can, for example, about 0.1 to 5 wt .-%, preferably 0.1 to about 2% by weight, based in each case on the finished detergent, be.
- the stabilizers come in particular for per-compounds and enzymes salts of polyphosphonic acids already mentioned. Is possible also the use of proteases with soluble calcium salts and a Calcium content of preferably about 1.2% by weight, based on the enzyme, are stabilized.
- ingredients in detergents that can be used to prepare the post-treated spray-dried component also include other builder substances.
- these additional builder substances are free of zeolite.
- the preferred further builder substances include inorganic silicates such as crystalline layered silicates, amorphous silicates or compounds composed of amorphous silicates and carbonates, but also organic builder substances such as citric acid / citrate or Sokalan DCS (R) .
- Preferred crystalline layered sodium silicates are those of the general formula NaMSi x O 2x + 1 .yH 2 O, where M is sodium or hydrogen, x is a number from 1.9 to 4 and y is a number from 0 to 20 and preferred values for x 2, 3 or 4.
