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 m 10-100%>100 mu m<150 mu m 0-50%<75 mu m 0-20%<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. |
