Abstract

Granular detergent compositions contain a low level of ammonium salt or salt of specific anion chlorine scavenger which is preferably protected in a particle. Such salts protect enzymes in the wash process. The preferred particles can also comprise, e.g., a suds-controlling silicone material which is substantially removed from contact with the surfactant component or alkaline component of the composition. The particles preferably use, e.g., a polyethylene glycol carrier, with preferably a small amount of fatty acid, in an irregularly shaped particle having a minimum dimension of at least about 0.05 cm.
