PARTICULATE BLEACH COMPOSITIONS

摘要

C 573 (R) of the Invention Particulate bleach (and detergent) compositions with improved bleach efficiency are disclosed comprising a particulate peroxy bleach 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.
