Definitions
- the invention relates to a bleaching or washing agent which, in addition to the ingredients customary for such agents, contains a bleaching system comprising an amino alcohol or D-amino acid oxidase and a substrate for this oxidase.
- bleaching agents usually contain an oxidizing agent based on oxygen, in particular a peracid, a peracid salt, hydrogen peroxide or a substance which supplies hydrogen peroxide under aqueous conditions of use. Since the bleaching effect of hydrogen peroxide alone is often perceived as inadequate, bleaching systems consisting of a per-compound which supplies hydrogen peroxide in water and a bleach activator which generates a peracid under perhydrolysis conditions are generally used. The most prominent example of such a bleaching system is the widely used combination of alkali perborate and N, N, N ', N'-tetraacetylethylenediamine.
- Oxidases are redox enzymes with the classification EC 1 (according to the classification of the Enzy ⁇ me Commission), which are generally flavin-dependent and whose oxidized form is capable. to oxidize a substrate. The resulting reduced form of the enzyme is reoxidized by molecular oxygen in aqueous systems, with hydrogen peroxide being formed as a further product.
- Examples of such enzymes and their sub- strates that emerge from the name of the enzyme are phenol oxidase, amino acid oxidase, xanthine oxidase, urate oxidase, alcohol oxidase, cholesterol oxidase and glucose oxidase.
