Abstract (en)
Granular detergent bleach compositions substantially free of phosphorus-containing material comprising as builder 1) a carbonate/calcite mixture, 2) an aluminosilicate cation exchange material, 3) a nitrilotriacetic acid compound or a mixture of 2) and 3); a peroxygen bleaching agent and a granular non-phosphorus bleach activator composition comprising: (a) 50-90% by weight of a bleach activator; (b) 5-45% by weight of an inert non-alkaline, non-phosphate water-soluble salt; and (c) 1-15% by weight of a water-soluble, low- to non-carboxylate containing film-forming polymeric material of average molecular weight of from 500-1,000,000. The granular non-phosphorus bleach activator composition has the advantage that it does not cause poisoning of calcite.
