Use of UV resistant active materials on hair
Polymers comprising at least one cationic functional group and at least one ultraviolet light-absorbing compound are disclosed herein. The resulting polymers exhibit ultraviolet light-absorbing properties and may be used in sunscreen compositions for skin and/or hair.
1. A method of using a sunscreen or hair color-protecting composition comprising applying to the hair or skin a composition comprising an ultraviolet light-absorbing polymer represented by the formula:
wherein;
a is an integer ranging from 2 to 100;
R 1 , and R 2 are independently hydrogen or alky;
X is selected from the group consisting of halide, sulfate, phosphate, benzoate, citrate, acetate, mesylate, nitrate, and fumarate; and
Z is an ultraviolet light-absorbing moiety selected from the group consisting of an avobenzone, benzimidazole, benzoxazole, benzotriazole, benzophenone, benzalmalonic acid ester, camphor, cinnamate, dibenzoylmethane, dihydropyrane, homosalate, imidazole, octinoxate, octisalate, octocrylene, oxybenzone, p-aminobenzoate, salicylate, triazone, or a derivative thereof.
2. A method of using a sunscreen or hair color-protecting composition comprising applying to the hair or skin a composition comprising an ultraviolet light-absorbing polymer represented by the formula:
wherein;
a is an integer ranging from 2 to 100;
b is an integer ranging from 0 to 3;
X is selected from the group consisting of halide, sulfate, phosphate, benzoate, citrate, acetate, mesylate, nitrate, and fumarate; and
Z is an ultraviolet light-absorbing moiety selected from the group consisting of an avobenzone, benzimidazole, benzoxazole, benzotriazole, benzophenone, benzalmalonic acid ester, camphor, cinnamate, dibenzoylmethane, dihydropyrane, homosalate, imidazole, octinoxate, octisalate, octocrylene, oxybenzone, p-aminobenzoate, salicylate, triazone, or a derivative thereof.
