  • Storage-stable liquid formulation comprising a laccase
    Patent number: 6136578
    Abstract: The present invention relates to a storage-stable liquid formulation comprising a laccase comprising (i) a laccase, (ii) at least one polyalcohol, which formulation has a pH which is more alkaline than the pH optimum of the laccase. It is also an object of the invention to provide a method for improving the storage-stability of liquid formulations comprising a laccase and the use of said liquid formulations for a personal care application or for bleaching or for textile applications such as dyeing of fabrics.

  • Re-formation of keratinous fibre cross links
    Patent number: 5899212
    Abstract: The present invention relates to a method for re-forming keratinous fibre cross links comprising contacting at least one oxidoreductase with the keratinous fibres for a sufficient period of time and under conditions sufficient to permit re-formation of keratinous fibre cross links. The method may be performed simultaneously with dyeing of said keratinous fibres. The invention also relates to the use at least one oxidoreductase for re-formation of keratinous fibre cross links.
