ABSTRACT:
The invention relates to the use of a certain class of lipases together with strong bleaching agents in detergent compositions. This class of lipases consists of fungal lipases ex Humicola lanuginosa or Thermomyces lanuginosus, and bacterial lipases which show a positive immunological cross-reaction with the antibody of the lipase produced by Chromobacter viscosum var. lipolyticum NRRL B-3673. The strong bleaching agents are stronger than the sodium perborate/TAED system, i.e. stronger than peracetic acid or they yield, on perhydrolysis, a peracid faster than the sodium perborate/TAED system.
