Abstract

Abstract A stable hair rinse conditioning composition to provide superior dry feel and high luster properties, comprising about 0.5-15% by weight of a polyvinyl pyrrolidone/vinyl acetate copolymer, about 0.1-10% by weight of at least one hydrophilic cationic quaternary ammonium compound, and a water-soluble nonionic cellulose polymer such as hydroxyethyl cellulose, hydroxymethylpropyl cellulose, etc., in an aqueous vehicle.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 245 words
A hair rinse conditioning composition which imparts superior dry feel and high luster properties to hair treated therewith and is readily removable from the hair by simply shampooing consisting essentially of by weight, a ternary mixture of 0.5% to 15% of a polyvinylpyrrolidone/vinyl acetate (PVP/VA) copolymer, in place of the fatty materials conventionally used, having a weight ratio of PVP/VA varying from 70:30 to 30:70; 0.1% to 10% of a hydrophilic cationic quaternary ammonium salt which corresponds to the following formula: ##STR4## wherein R and R 1 each is an alkyl radical containing 1-3 carbon atoms; R 2 is a polyoxyalkylene radical represented by either [CH 2 CH(R 4 )O] n H or alkylene O[CH 2 CH(R 4 )O] n H where R 4 is an alkyl radical of 1-2 carbon atoms; n is 3 to 60, and alkylene contains not more than three carbon atoms; X is a lower alkyl or alkenyl radical containing 1 to 4 carbon atoms or is an alkaryl radical containing from 7 to 9 carbon atoms; and A is an anion selected from the group consisting of chlorine, bromine, hydroxy, sulfate, metho- or ethosulfate, nitrate, phosphate, acetate, formate and sulfonate; the weight ratio of said quaternary salt to said copolymer being in the range of 1:5 to 20:1; and 0.1% to 4% of a water soluble nonionic cellulose polymer in 71% to 99.3% of an aqueous medium, said composition having a pH in the range of 3 to 6.
Claim 2
Dependent Claim 245 words
A hair rinse conditioning composition which imparts superior dry feel and high luster properties to hair treated therewith and is readily removable from the hair by simply shampooing consisting essentially of by weight, a ternary mixture of 0.5% to 15% of a polyvinylpyrrolidone/vinyl acetate (PVP/VA) copolymer, in place of the fatty materials conventionally used, having a weight ratio of PVP/VA varying from 70:30 to 30:70; 0.1% to 10% of a hydrophilic cationic quaternary ammonium salt which corresponds to the following formula: ##STR4## wherein R and R 1 each is an alkyl radical containing 1-3 carbon atoms; R 2 is a polyoxyalkylene radical represented by either [CH 2 CH(R 4 )O] n H or alkylene O[CH 2 CH(R 4 )O] n H where R 4 is an alkyl radical of 1-2 carbon atoms; n is 3 to 60, and alkylene contains not more than three carbon atoms; X is a lower alkyl or alkenyl radical containing 1 to 4 carbon atoms or is an alkaryl radical containing from 7 to 9 carbon atoms; and A is an anion selected from the group consisting of chlorine, bromine, hydroxy, sulfate, metho- or ethosulfate, nitrate, phosphate, acetate, formate and sulfonate; the weight ratio of said quaternary salt to said copolymer being in the range of 1:5 to 20:1; and 0.1% to 4% of a water soluble nonionic cellulose polymer in 71% to 99.3% of an aqueous medium, said composition having a pH in the range of 3 to 6.
