Abstract:
A rinse-off hair care composition comprising, by weight of the hair care composition:A. from about 0.5% to about 10%, by weight, of a polypropylene glycol having a weight average molecular weight of from about 1,000 g/mol to about 60,000 g/mol, the polypropylene glycol being selected from the group consisting of a single-polypropylene glycol-chain segment polymer, a multi-polypropylene glycol-chain segment polymer, and mixtures thereof, and wherein the polypropylene glycol has a solubility in water at 25Â° C. of less than about 1 g/100 g water, wherein the single-polypropylene glycol-chain segment polymer has the formula: HOâ€”(C3H6O)aHâ€ƒâ€ƒ(Formula I), â€ƒwherein a is a value from about 4 to about 400, and wherein the multi-polypropylene glycol-chain segment polymer has the formula: â€ƒwherein n is a value from about 0 to about 10, wherein each R is independently selected from the group consisting of H, and C1-C30 alkyl, wherein each b is independently a value from 0 to 2, wherein c and d are independently a value from 0 to 2, wherein b+c+d is at least 2, wherein each e is independently a value of 0 or 1, and wherein each x, y, and z is independently a value of from about 1 to about 120; B. from about 0.5% to about 10% of an ester oil of the formula: R1COOR1â€ƒâ€ƒ(Formula V), wherein each R1 is independently a C1-C22 alkyl, and wherein the HLB value of the ester oil is less than about 4;C. from about 60% to about 99% of a gel matrix comprising a cationic surfactant, a solid fatty compound, and water, wherein the weight ratio of cationic surfactant to solid fatty compound is from about 1:1 to about 1.20; and D. the balance being other additional components, wherein the viscosity of the hair care composition is from about 5,000 cps to about 40,000 cps, wherein the hair care composition is a rinse-off hair conditioning composition.
