ABSTRACT:
A fabric-safe bleaching and cleaning detergent composition comprising a bleach stable surfactant and a polymer coated halogenated glycoluril compound having the formula ##STR1## wherein each R is independently selected from hydrogen, C.sub.1 -C.sub.10 straight or branched chain alkyl, aryl or alkyl substituted aryl; each X is independently selected from hydrogen, fluorine, chlorine, bromine and iodine and at least one X is not hydrogen and n is 0 or 1. 1,3,4,6-tetrachloroglycoluril is the preferred bleaching agent. The polymer coating is capable of hydrating and dissolving at a pH of greater than 6.0, preferably 7.2 to 11.0, and more preferably 9.5 to 11.0. Polymeric pharmaceutical enteric coating materials are particularly suitable as a coating material for the present invention.
