Abstract (en)
[origin: EP0723006A2] Improved detergent compositions, especially granular automatic dishwashing detergents, comprising detersive enzymes (such as proteases and/or amylases), and bleaches (such as hypochlorite or sodium dichloroisocyanurate) capable of deactivating the enzymes. Also, methods for achieving improved performance from combinations of these ingredients via an improved delivery sequence and profile, specifically involving release of bleach prior to enzyme, are provided. Preferred compositions comprise bleach scavengers (such as ammonium sulfate) and enzyme dissolution-delaying polymers (such as film-forming polyesters) employed in compositions which allow destruction of the bleach or its conversion to an enzyme-compatible form prior to dispersal of enzyme in the wash.
