CATIONIC POLYMERS HAVING CLAY SOIL REMOVAL/ANTI-REDEPOSITION PROPERTIES USEFUL IN DETERGENT COMPOSITIONS ABSTRACT 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, C1-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 hydroxyalky- lene, 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.
