Abstract
Cleaning compositions and laundry detergents comprising amphoteric polymers are disclosed. The amphoteric polymers may be comb polymers having polycarboxylate backbones and polyalkoxylate tentacles. In particular, the amphoteric polymer includes: a cationic group structure unit derived from a cationic group-containing monomer; and a carboxyl structure unit derived from a carboxyl group-containing monomer. The cationic group structure unit may be present at a level of 1% to 99% by mass based on 100% by mass of all structure units derived from all monomers in the amphoteric polymer. The carboxyl structure unit may be present at a level of 1% to 99% by mass based on 100% by mass of all the structure units derived from all the monomers in the amphoteric polymer. The cleaning compositions have high anti-soil redeposition ability and solubility with surfactants.
