Hair lightening compositions and methods of use
The present disclosure relates to hair care compositions such as hair treatment compositions and hair lightening compositions, methods for treating hair (e.g., lightening hair), and to kits comprising the compositions. The components of the hair treatment compositions may be included in hair lightening compositions and used to lighten and/or color hair. The hair treatment compositions typically include: (a) one or more polycarboxylic acids, and/or a salt thereof; (b) one or more amino acids, and/or a salt thereof; and optionally (c) one or more cationic conditioning agents. The hair lightening compositions further include (d) one or more bleaching agents.
1. A hair treatment composition comprising:
(a) citric acid and/or a salt thereof;
(b) glycine and/or a salt thereof;
(c) optionally one or more cationic conditioning agents;
(e) optionally at least one oil;
(f) optionally at least one thickening agent; and
(g) one or more anionic surfactants;
wherein the total amount of compounds chosen from citric acid and salts thereof ranges from about 1 wt % to about 5 wt % based on the total weight of the composition,
wherein the total amount of compounds chosen from glycine and salts thereof ranges from about 0.1 wt % to about 2 wt % based on the total weight of the composition,
wherein the composition comprises a total amount of compounds chosen from (a) citric acid and salts thereof and (b) glycine and salts thereof in a weight ratio of (a):(b) ranging from about 2:1 to about 10:1, and
wherein the composition is essentially anhydrous, comprising no more than 3 wt % water, based on the total weight of the composition.
2. The hair treatment composition of claim 1 ,

3. The hair treatment composition of claim 1 , wherein the composition is free or essentially free of cationic conditioning compounds.
4. The hair treatment composition of claim 1 , wherein the composition is free or essentially free of peptides.
5. A hair lightening composition comprising:
(a) about 1 to about 5 wt % of citric acid and/or a salt thereof;
(b) about 0.1 to about 2 wt % of glycine and/or a salt thereof;
(c) optionally, one or more cationic conditioning agents;
(d) one or more bleaching agents;
(e) about 1 to about 5 wt % of at least one oil;
(f) about 0.5 to about 2 wt % of at least one thickening agent; and
(g) one or more anionic surfactants;
wherein the composition comprises a total amount of compounds chosen from (a) citric acid and salts thereof and (b) glycine and salts thereof in a weight ratio of (a):(b) ranging from about 2:1 to about 10:1;
wherein all amounts are based on the total weight of the composition; and
wherein the composition is essentially anhydrous, comprising no more than 3 wt % water, based on the total weight of the composition.
6. The hair lightening composition of claim 5 , wherein the weight ratio of (a):(b) ranges from about 2:1 to about 8:1.
7. The hair lightening composition of claim 5 , comprising about 0.6 wt % of compounds chosen from (b) glycine and/or a salt thereof.
8. The hair lightening composition of claim 5 , comprising about 3.6 wt % of compounds chosen from (a) citric acid and/or a salt thereof.
9. The hair lightening composition of claim 5 , wherein the one or more bleaching agents are selected from the group consisting of one or more peroxides, persulfates, perborates, and percarbonates.
10. The hair lightening composition of claim 9 comprising one or more persulfates selected from the group consisting of sodium persulfate, potassium persulfate, ammonium persulfate, and a mixture thereof.
11. The hair lightening composition of claim 5 comprising:
(d) about 20 to about 80 wt % of the one or more bleaching agents, based on the total weight of the hair lightening composition.
12. The hair lightening composition of claim 5 , wherein the one or more oils comprises mineral oil.
13. The hair lightening composition of claim 5 , wherein the one or more thickening agents comprises guar gum.
14. The hair lightening composition of claim 5 , comprising at least two thickening agents.
15. The hair lightening composition of claim 5 , wherein the composition is free or essentially free of cationic conditioning compounds.
16. The hair lightening composition of claim 5 , wherein the composition is free or essentially free of peptides.
17. A hair lightening composition comprising:
(a) about 0.1 to about 10 wt % of citric acid and/or a salt thereof;
(b) about 0.01 to about 5 wt % of one or more aliphatic amino acids selected from the group consisting of glycine, alanine, valine, leucine, isoleucine, a salt thereof, and a mixture thereof;
(d) about 20 to about 80 wt. % of one or more persulfates;
(e) about 0.1 to about 10 wt % of one or more oils;
(f) about 0.1 to about 10 wt % of one or more thickening agents;
(g) about 0.1 to about 10 wt % of one or more anionic surfactants; and
(h) about 1 to about 40 wt % of one or more alkalizing agents,
wherein the composition is free or essentially free of cationic conditioning agents;
wherein all amounts are based on the total weight of the composition; and
wherein the composition is essentially anhydrous, comprising no more than 3 wt % water, based on the total weight of the hair lightening composition.
18. A kit comprising:
i. the hair lightening composition of claim 5 ; and
ii. an aqueous developer composition comprising one or more peroxides; and
iii. optionally, a third composition comprising one or more hair conditioning agents and/or one or more direct dyes.
19. A method for lightening hair comprising:
