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.
