Definitions

  • the present invention relates to enzyme-containing detergents and cleaning agents which, in addition to the usual constituents, contain an amylase from Bacillus amyloliquefaciens and certain bleach-activating active ingredients.
  • detergents In addition to the ingredients that are indispensable for the washing process, such as surfactants and builder materials, detergents generally contain further constituents, which can be summarized under the term washing aids and which comprise 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, the ⁇ -amylase from Bacillus amyloliquefaciens and at least one compound of the general formula I,
  • Another object of the invention is the use of a corresponding combination to increase the cleaning performance of detergents and cleaning agents, in particular compared to starchy and / or colored, in particular tea-based soiling, when used in aqueous washing and cleaning solutions, in particular, which contain a peroxygen compound.
  • the cleaning performance in relation to colored soiling is to be understood in its broadest meaning and includes both the bleaching of dirt on the textile and the bleaching of dirt detached from the textile in the wash liquor and also the oxidative destruction of textile colors in the wash liquor, which detach from textiles under the washing conditions before they can be drawn onto textiles of a different color.
  • this term means both the bleaching of dirt located on the hard surface, in particular tea, and the bleaching of dirt located in the dishwashing liquor and detached from the hard surface.
