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, C.sub.1 -C.sub.4 alkyl or hydroxyalkyl 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).sub.m (CH.sub.2 CH.sub.2 O).sub.n ]--, wherein R' is C.sub.3 -C.sub.4 alkylene or hydroxyalkylene, m and n are numbers such that the moiety --(CH.sub.2 CH.sub.2 O).sub.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.
