Abstract
Detergent compositions include water soluble polymers which serve as builders, lime soap dispersants, and antiredeposition agents. The water soluble polymers, which fall into two structural classes, are especially useful in commerical heavy duty liquid detergent compositions, with which they are compatible in effective amounts. The water soluble polymers enhance several detergent properties such as antiredeposition and lime soap dispersants without a concomittant loss in other detergent composition characteristics. Further, the polymers are compatible with enzyme containing liquid detergents. In the first structural class surfactant radicals are distributed along the polymer chain, which also includes pendent carboxyl and/or carboxylate salt radicals. In the second structural class the polymers are terminated by a surfactant radical. The water soluble polymers are also effective dispersants for a number of particulate materials including kaolin clay and powdered coal, and inhibit the precipitation of calcium chloride and barium sulfate.
