Abstract
A novel bleach composition is disclosed comprising a sulfatase enzyme and a peroxydisulfate which composition, in aqueous solution, generates the more reactive peroxymonsulfate bleach compound. Detergent compositions and bleach processes are also disclosed wherein the peroxymonsulfate is produced in situ to provide bleach functions with greatly reduced dye damage, particularly useful to remove blood stains from textile materials.
Claims27
A bleach composition comprising a sulfatase enzyme and a stable, water soluble peroxydisulfate ion forming compound which, in the presence of the enzyme, hydrolyses in aqueous solution to provide peroxymonosulfate ions.
A bleach composition comprising an aqueous solution of a sulfatase enzyme and a stable, water soluble peroxydisulfate ion forming compound which, in the presence of the enzyme, hydrolyses in aqueous solution to form peroxymonosulfate ions.
A process of bleaching articles which comprises contacting the article with a bleach effective amount of an aqueous composition comprising a sulfatase enzyme and a stable, water soluble peroxydisulfate ion producing compound which, in the presence of the enzyme, hydrolyses in aqueous solution to form peroxy-monosulfate ions.
