Abstract:
A bleach activator for detergent compositions in which the activator exhibits improved properties of activator release, abrasion resistance, and shelf life, said bleach activator comprising:a granulated compressed dry admixture of an ammonium nitrile composition of the formula ##STR3## in which R.sup.1 and R.sup.2 are C.sub.1 -C.sub.4 -alkyl and X is an anion and an auxiliary granulating composition; anda substantially uniform, thin, thermally conditioned coating on the surfaces of the respective individual granules of said compressed dry admixture of a substance that moderates the physical contact between the granules and other substances in a detergent composition;said granulated dry admixture has a melting point above 100.degree. C.said auxiliary granulating composition has a melting point sufficiently higher than the melting point of said coating substance which has a melting point of from 30.degree. C. to 100.degree. C., thereby preventing the said granulated dry admixture composition from melting and the granules from disintegrating when the coating substance is applied as a melt or heated to its melting temperature.
