Detergent compositions which comprise from about 0.05 to about 95% by weight of a water-soluble cationic compound having clay soil removalanti-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.
Also, water-soluble cationic polymers having clay soil removal/anti-redeposition properties, which comprise a polymer backbone, at least two M groups and at least one L-X group, wherein M is a cationic group attached to or integral with the backbone and contains an N+ positively charged center; X is a nonionic group selected from the group consisting of H, Ci-C4 alkyl or hydroxy-alkyl ester or ether groups, or mixtures thereof; and L is a hydrophilic chain connecting groups M and X or connecting X to the polymer backbone. L also contains the polyoxyalkylene moiety -[(R'O)m(CH2CH2O)n]-, wherein R' is C3-C4 alkylene or hydroxyalkylene, m and n are numbers such that the moiety -(CH2CH2O)n- is at least about 50% by weight of said polyoxyalkylene moiety, and n is at least about 3. These cationic polymers are useful in detergent compositions.
