ABSTRACT:
Water-soluble zwitterionic polymers having clay soil removal/anti-redeposition properties, which comprise a polymer backbone, at least 2 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 an anionic group or a mixture of anionic and nonionic groups; 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 -- comprises at least about 50% by weight of said polyoxyalkylene moiety, and n is at least about 3. These zwitterionic polymers are useful in detergent compositions at from about 0.05 to about 95% by weight. In addition to the polymer, 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.
