Cationic polymers having clay soil removal/anti- redeposition properties useful in detergent compositions

Abstract From the Canadian patent

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 hydroxyalkylene, m and n are numbers such that the moiety -(CH2CH2O)n- is at …
