Abstract: Particulate bleach (and detergent) compositions with improved bleach efficiency are disclosed comprising a particulate peroxybleach compound and tetraacetyl ethylene diamine (TAED), said TAED having the following particle size distribution as determined by sieve analysis:0-20%>150 .mu.m10-100%>100 .mu.m<150 .mu.m0-50%<75 .mu.m0-20%<50 .mu.m,and being contained in granules in combination with a granulating agent, said granules having particle size ranging from 100-2000 .mu.m and comprising 10-99% by weight of TAED. The particulate bleach composition does not suffer from significant sedimentation and/or dissolution problems and does not suffer from significant decomposition problems during storage.
