Abstract: Aqueous peroxide bleaching compositions including organic components such as surfactants, fluorescent whiteners and dyes are effectively stabilized by the addition of a stabilizing system comprising stabilizing effective amounts of a heavy metal chelating or sequestering agent and an aromatic amine free radical scavenging agent. Both agents must be present to achieve maximum stability. The aromatic amine free radical scavenging agent is preferably a primary or secondary aryl amine having at least one hydrogen on the nitrogen of the amine. The stabilizing system stabilizes the organic component as well as the peroxide oxidizing agent.

Abstract: For replacing cleaning compositions based on 1,1,2-trichloro-1,2,2-trifluoroethane (F113), the invention provides a composition comprising 55 to 79.5% by weight of 1,1-dichloro-1-fluoroethane (F141b), 20 to 40% by weight of methyl formate and 0.5 to 5% of methanol.

Abstract: The invention relates to a detergent composition comprising lipases. By inclusion of a certain immunologically defined class of lipases in a detergent composition which comprises as detergent-active material solely an anionic synthetic detergent, and as builder a water-soluble inorganic or organic builder salt, an improved overall detergency is obtained. The builder salt is typically sodium tripolyphosphate or sodium carbonate, and the lipase is typically obtained from certain Pseudomonas or Chromobacter strains.
