摘要
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 min O)m(CH2CH2O)n]-, wherein R min is C3-C4 alkylene or hydroxyalkylene, m and n are numbers such that the moiety -(CH2CH2O)n- comprises at least about 50% by eight 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.
