ABSTRACT:
A powdered laundry detergent composition comprising an active surfactant, at least about 70 wt. % of a water soluble alkaline carbonate salt, e.g., sodium carbonate, about 0.1 to 2 wt. % of a phosphorus-containing sequestering agent, e.g., sodium tripolyphosphate (STPP), about 0.1 to 2 wt. % of a polymeric polycarboxylate, e.g., a polyacrylate or a polymaleate, and about 1-12 wt. % water. Use of the foregoing detergent composition provides excellent cleaning and whitening of fabrics while avoiding the problem of eutrophication which occurs when a substantial amount of a phosphorus containing builder such as STPP is present in the composition, and while minimizing the problem of fabric encrustation often present when the composition contains a large amount of carbonate builder.
