ABSTRACT:
A powdered laundry detergent composition is provided comprising an active surfactant, at least about 70 wt. % of a water soluble alkaline carbonate salt, and about 0.1 to 5.0 wt. % of a terpolymer of acrylic acid, maleic acid, and acrylamide.
Use of the foregoing detergent composition provides excellent cleaning and whitening of fabrics while avoiding any serious 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.
