Abstract
Detergent compositions which comprise from about 0.05 to about 95% by weight of a water-soluble ethoxylated amine polymer having clay soil removal/anti-redeposition properties. These polymers comprise a polymer backbone other than a polyalkyleneamine or polyalkyleneimine backbone, and at least 2 M groups and at least one L-X group, wherein M is a tertiary amine group attached to or integral with the backbone; X is a nonionic group, an anionic group or mixture 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 -- comprises at least about 50% by weight of said polyoxyalkylene moiety, and n is at least about 3. In addition to the ethoxylated amine polymers, 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.
