Abstract
The disclosure relates to compositions for altering the color of keratin fibers and methods of using the compositions. The compositions comprise (a) a bonding system comprising: (i) at least one first bonding agent chosen from citric acid and/or salts thereof, and (ii) at least one second bonding agent chosen from amino acids, amino sulfonic acids, salts thereof, or combinations thereof; (b) at least one fatty alcohol; (c) at least one fatty acid; (d) at least one alkyl polyglucoside; (e) at least one alkalizing agent; and (f) at least one solvent. The compositions can further comprise one or more oxidation dyes, couplers, oxidizing agents, or combinations thereof.
Claims19
A hair color-altering composition comprising:
- (a) a bonding system comprising:
- (i) at least one first bonding agent chosen from citric acid and/or salts thereof;
- and
- (ii) at least one second bonding agent chosen from amino acids, amino sulfonic acids, salts thereof, or combinations of two or more thereof;
- (b) at least one fatty alcohol;
- (c) at least one fatty acid;
- (d) at least one alkyl polyglucoside;
- (e) at least one alkalizing agent;
- and
- (f) water;
- wherein the weight ratio of the first bonding agent(s) to the second bonding agent(s) ranges from about 1:1 to about 2:1,
- wherein the composition is essentially free of cationic polymers, and
- wherein the pH of the hair color-altering composition is greater than 7.
A hair color-altering base composition comprising:
- (a) a bonding system comprising:
- (i) at least one first bonding agent comprising from about 0.1% to about 5% of citric acid and/or salts thereof;
- and
- (ii) at least one second bonding agent chosen from amino acids, amino sulfonic acids, salts thereof, or combinations of two or more thereof, wherein the total amount of second bonding agent(s) ranges from about 0.1% to about 5%;
- (b) at least one fatty alcohol;
- (c) at least one fatty acid;
- (d) at least one alkyl polyglucoside;
- (e) at least one alkalizing agent;
- and
- (f) water;
- wherein all amounts are by weight, relative to the total weight of the hair color-altering base composition;
- wherein the composition is essentially free of cationic polymers;
- and
- wherein the pH of the hair color-altering base composition is greater than 7.
A method for altering the color of hair comprising:
- (1) applying to the hair a hair color-altering composition comprising:
- (a) a bonding system comprising:
- (i) at least one first bonding agent chosen from citric acid and/or salts thereof;
- and/or
- (ii) at least one second bonding agent chosen from amino acids, amino sulfonic acids, salts thereof, or combinations of two or more thereof;
- (b) at least one fatty alcohol;
- (c) at least one fatty acid;
- (d) at least one alkyl polyglucoside;
- (e) at least one alkalizing agent;
- and
- (f) water;
- wherein the weight ratio of the first bonding agent(s) to the second bonding agent(s) ranges from about 1:1 to about 2:1,
- wherein the composition is essentially free of cationic polymers;
- and
- wherein the pH of the hair color-altering composition is greater than 7;
- and
- (2) rinsing the hair color-altering composition from the hair after a leave-in period ranging from about 1 minute to about 60 minutes.
