Definitions

  • the present invention relates to enzyme-containing detergents which, in addition to the usual constituents, contain an amylase from Bacillus amyloliquefaciens and an active ingredient which inhibits color transfer.
  • detergents In addition to the ingredients that are indispensable for the washing process, such as surfactants and builder materials, detergents generally contain other ingredients, which can be summarized under the term washing aids and which include such different active ingredient groups as foam regulators, graying inhibitors, bleaching agents, bleach activators and color transfer inhibitors. Such auxiliaries also include substances which support the surfactant performance through the enzymatic degradation of soiling on the textile. The same applies analogously to cleaning agents for hard surfaces. In addition to the proteases that support protein removal and the fat-cleaving lipases, amylases are of particular importance.
  • Amylases have the task of facilitating the removal of starchy soiling by the catalytic hydrolysis of the starch polysaccharide and for this purpose have been used for a long time in detergents for dishes, but also in detergents for use in textile washing. For the most part, it was previously a thermostable amylase from Bacillus licheniformis, which is commercially available, for example, under the name Termamyl®. More recently, such agents have increasingly used genetically modified amylases, that is to say with amino acid sequences modified in comparison to naturally occurring amylases with the aid of genetic engineering methods. In addition to increasing their performance, the genetic modification of amylases essentially aims to increase the stability of the enzyme, in particular against the attack of oxidizing agents.
  • the invention therefore relates to an amylase-containing washing or cleaning agent which contains .alpha.-amylase from Bacillus amyloliquefaciens and a percarboxylic acid and / or its alkali salt in addition to the usual ingredients compatible with such constituents.
