    摘要： There is provided a laundry composition comprising i) at least one laundry component selected from the group consisting of surfactants, softening agents, and mixtures thereof and ii) at least one ampholytic polymer comprising, as polymerized units, a) 20% to 90% by weight, based on the solid weight of said ampholytic polymer, at least one cationic monomer, b) 10% to 70% by weight, based on the solid weight of said ampholytic polymer, at least one anionic monomer, and c) 0% to 90% by weight, based on the solid weight of said ampholytic polymer, at least one nonionic monomer; wherein the equivalent ratio of said monomer a) to said monomer b) is from 0.33:1 to 1.2:1; and wherein said ampholytic polymer has weight-average molecular weight of 50,000 or less. Further provided is a method of laundering textiles comprising treating said textiles with such laundry compositions.
