Abstract

A bleach-containing detergent composition which contains a peroxygen bleaching compound and a bleach activator is disclosed. The bleach activator is in the form of particles having a mean particle diameter of 200 microns to 2000 microns. Also disclosed are bleach activator particles in the form of substantially cylindrically-shaped extrudates having a mean extrudate length of from about 500 microns to about 3500 microns and a mean extrudate diameter of from about 450 microns to about 850 microns.
