Publication number: 20120227195Abstract: 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.Type: ApplicationFiled: December 16, 2011Publication date: September 13, 2012Inventors: Koushik Mukherjee, Kenneth Nathan Price, Hemmi Akiko, Yoneda Atsuro, Michitaka Daisuke, Nakanishi Sachiko
