  • Patent number: 8541357
    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.

  • Publication number: 20120227195
    Abstract: Cleaning compositions and laundry detergents comprising polyalkylene glycol-based polymers are disclosed. The polyalkylene glycol-based polymers are polyoxyalkylene-oxide capped polyalkylene-oxide-polycarboxylate comb polymers. The polyalkylene glycol-based polymer includes: a glycol-based structure unit derived from a polyalkylene glycol-based monomer, and a carboxyl-based structure unit derived from a carboxyl group-containing monomer. The glycol-based 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 polyalkylene glycol-based 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 polyalkylene glycol-based polymer. The cleaning compositions have high anti-soil redeposition ability in washing treatment and high solubility and compatibility with surfactants.
