Abstract

Water-soluble ethoxylated amine oxides having clay soil removal/anti-redeposition properties are disclosed herein. These amine oxides are selected from ethoxylated monoamine oxides, ethoxylated diamine oxides, ethoxylated polyamine oxides, ethoxylated amine oxide polymers, and mixtures thereof. These amine oxides are useful at from about 0.05 to about 95% by weight in detergent compositions which further comprise from about 1 to about 75% by weight of a nonionic, anionic, ampholytic, zwitterionic, or cationic detergent surfactant or mixture thereof. In addition to these detergent surfactants, the detergent composition can optionally comprise from 0 to about 80% by weight of a detergent builder.
