Abstract
A method, a kit and a first composition for treating hair are provided. The method for treating hair comprises applying to the hair a first composition comprising in a cosmetically acceptable carrier, one or more at least bi-functional carboxylic acids, or cosmetically acceptable salts thereof, or mixtures thereof, and applying to the hair a second composition comprising in a cosmetically acceptable carrier, one or more at least bi-functional carboxylic acids, or cosmetically acceptable salts thereof, or mixtures thereof, wherein the first composition has a pH from 7 to 13 and the second composition has a pH from 3 to 7.
Claims12
A method for treating hair comprising:
- (a) mixing a first composition having a pH from 7 to 13 with a hair treatment composition to form a mixed composition, the hair treatment composition comprising one of a bleaching agent, a coloring agent, and a permanent hair waving agent;
- (b1) applying to the hair the mixed composition having a pH from 7 to 13;
- and
- (c) applying to the hair a second composition having a pH from 3 to 7, wherein
- each of the first composition and the second composition comprises in a cosmetically acceptable carrier, one or more at least bi-functional carboxylic acids of Formula 1, or cosmetically acceptable salts thereof, or mixtures thereof,
- wherein Formula 1 is HOOC—Ra-(O—Rb)n-COOH, wherein Ra is selected from the group consisting of C1-C10 alkylene, C1-C10 cycloalkylene, C1-C10 alkenylene, C6-C12 (alkyl)arylene, Rb is C2-C4 alkylene, n is an integer from 0 to 4, wherein Ra or each Rb are substituted with one or more substituents selected from —COOH, —OH, —NH2, —SH, and ═O, and wherein the total number of carbon atoms in Ra plus Rb is 12 or less.
A kit comprising:
- (1) a first composition having a pH from 7 to 13;
- (2) a second composition having a pH from 3 to 7;
- wherein each of the first and the second composition comprises in a cosmetically acceptable carrier, one or more at least bi-functional carboxylic acids of Formula 1, or cosmetically acceptable salts thereof, or mixtures thereof;
- wherein Formula 1 is HOOC—Ra-(O—Rb)n-COOH, wherein Ra is selected from the group consisting of C1-C10 alkylene, C1-C10 cycloalkylene, C1-C10 alkenylene, C6-C12 (alkyl)arylene, Rb is C2-C4 alkylene, n is an integer from 0 to 4, wherein Ra or each Rb are substituted with one or more substituents selected from —COOH, —OH, —NH2, —SH, and ═O, and wherein the total number of carbon atoms in Ra plus Rb is 12 or less;
- wherein the first composition, and the second composition are, separately packaged.
