Definitions

  • the present invention relates to enzyme-containing detergents or cleaners which, in addition to customary constituents, contain combinations of chlorophyllases and at least one further hydrolase, preferably a lipase, particularly preferably a galactolipase.
  • detergents In addition to the ingredients indispensable for the washing process, such as surfactants and builders, detergents generally contain further constituents, which can be summarized by the term washing aids and which comprise such different active ingredient groups as foam regulators, grayness inhibitors, bleaching agents and color transfer inhibitors. Such adjuvants also include substances which aid surfactant performance by the enzymatic degradation of soil soils. The same applies mutatis mutandis to cleaners for hard surfaces.
  • the amylases which have the task of facilitating the removal of starch-containing stains by the catalytic hydrolysis of the starch polysaccharide, and the cellulases are of particular importance.
  • inorganic peroxygen compounds especially hydrogen peroxide and solid peroxygen compounds which dissolve in water to release hydrogen peroxide, such as sodium perborate and sodium carbonate perhydrate, have long been used as oxidizing agents for disinfecting and bleaching purposes.

Abstract

L'invention concerne des lessives et détergents contenant une combinaison de chlorophyllase et d'une autre hydrolase, de préférence d'une lipase, notamment de galactolipase. La combinaison de chlorophyllase et de galactolipase améliore la puissance de nettoyage, notamment dans le cas de souillures contenant de la chlorophylle, par rapport à la puissance de nettoyage obtenue avec les enzymes prises séparément.
