LAUNDRY DETERGENT COMPOSITIONS

摘要

A detergent composition which comprises: a surfactant, a builder, a fluorescer; one or more of a bleach precursor which is preferably N,N,N'N'-tetra-acetyl ethylene diamine or sodium nonanoyloxy benzene sulphonate, one or more of a hydrogen peroxide source which is preferably an alkali metal perborate or percarbonate. Optionally it comprises a nitrogen-containing dye binding polymer selected from polymers and co-polymers of vinyl-pyrrolidone, vinyl-pyridine N-oxide, and vinyl-imidazole, and mixtures thereof. The composition is essentially free of copper binding species, other than those which are deactivated by calcium salts.
