Publication number: 20160015622Abstract: A conditioning and cleansing composition comprising at least one detersive surfactant, a silicone conditioning agent and a nonionic, amphiphilic polymer that mitigates the loss silicone deposition on keratinous substrates is disclosed. The nonionic, amphiphilic polymer is prepared by polymerizing a monomer composition comprising: a) from about 55 to about 95 wt. % of at least one vinyl amide monomer (based on the weight of the total monomers present); b) from about 5 to about 45 wt. % of at least one vinyl ester of an aliphatic carboxylic acid containing an acyl moiety having 2 to 22 carbon atoms (based on the weight of the total monomers present); c) from about 0 to about 1 wt. % of at least one polyunsaturated crosslinking monomer containing at least two polymerizable ethylenically unsaturated moieties (based on the total dry weight of the polymer); d) from about 0 to about 10 wt.Type: ApplicationFiled: March 3, 2014Publication date: January 21, 2016Applicant: LUBRIZOL ADVANCED MATERIALS INC.Inventors: Denise W.
