Abstract
Abstract Detergent compositions which comprise from about 0.05 to about 95% by weight of a water-soluble cationic compound having clay soil removal/anti-redeposition properties. These compounds are selected from ethoxylated cationic monoamines, ethoxylated cationic diamines, ethoxylated cationic polyamines, ethoxylated cationic polymers, and mixtures thereof. In addition to the cationic compounds, the detergent compositions 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.
