Patent number: 4861509Abstract: 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.Type: GrantFiled: June 23, 1988Date of Patent: August 29, 1989Assignee: Lever Brothers CompanyInventors: Johannes M. Cornelissen, Jan Klugkist, Cornelis A. Lagerwaard, Swarthoff Ton, David Thom, David Thom

Patent number: 4832864Abstract: Aqueous processes and compositions of the invention for obtaining a "stone-washed", distressed or "used and abused" look in clothing, particularly in the panels and seams of denim jeans and jackets involve compositions that are stone-free that avoid mechanical abrasion of the fabric. In particular, the process and composition of the invention used to obtain the distressed, "stone-washed" or "acid washed look" are free of common pumice or pumice-bleach compositions, used in large institutional-size laundry machines, and rely solely on the chemical action of aqueous treatment compositions. The aqueous treatments can be made from liquid or solid concentrates.Type: GrantFiled: September 15, 1987Date of Patent: May 23, 1989Assignee: Ecolab Inc.Inventor: Lynne A. Olson
