Patent number: 4525292Abstract: This invention relates to bleaching detergent compositions that provide effective and efficient surface bleaching of textiles over a wide range of bleach detergent solution temperatures. Surface bleaching of textiles is bleaching wherein the bleaching mechanism takes place on the textile surface and, thereby, removes stains and/or soils. The bleaching compositions within the invention contain either a mixture of peroxygen bleaches capable of yielding hydrogen peroxide in aqueous solutions and specific bleach activators or the corresponding percarboxylic acids and either a sulfosuccinate, a nitrilotriacetate or mixtures thereof as a bleach promoter.Type: GrantFiled: March 7, 1983Date of Patent: June 25, 1985Inventors: Mark E. Cushman, Lawrence A. Gilbert
