  • Detergents and washing aids that contain enzymes have been known for a long time.
  • proteolytic enzymes have been used in textile detergents for over 60 years and have proven to be a very effective cleaning component against protein soiling.
  • the advantageous effect of cellulolytic enzymes is not primarily in the field of removing textile stains, but rather is due to the textile softening, color-refreshing and textile surface image-improving properties of this enzyme.
  • European patent application EP-A-0 271 004 discloses cellulases with a certain non-degradation index which can be used in detergents which contain anionic and nonionic surfactant and protease.
  • Japanese patent application JP-A-1 304 193 discloses a detergent which contains 12% alkylbenzenesulfonate, 4% alkyl sulfate, 4% ethoxylated fatty alcohol, 18% zeolite, 2% water-soluble organic builder, 0.5% protease and 2% cellulase .
  • German published patent application DE 41 16 701 A1 relates to a sodium percarbonate produced in a certain way, which can be incorporated into detergents which contain, for example, anionic surfactants, nonionic surfactants, zeolite, water-soluble organic builders, protease and cellulase.
