Abstract

The instant disclosure relates to hair cosmetic compositions that impart desirable cosmetic properties to hair, in particular, curly hair. The hair cosmetic compositions typically include a nonionic gum, a cationic guar gum, a cationic cellulosic quaternary ammonium compound, an acrylate-based polymer, a polyol and water.

Claims (36)

1. A hair cosmetic composition comprising:

(a) about 0.1 to about 8 wt. % of hydroxypropyl guar;

(b) about 0.1 to about 1.8 wt. % of hydroxypropyl guar hydroxypropyltrimonium chloride;

(c) 0.1 to about 4 wt. % of a copolymer of hydroxyethyl cellulose and of diallyldimethylammonium chloride;

(d) about 0.5 to about 8 wt. % of at least one polymer selected from VP/dimethylamino ethylmethacrylate copolymer, VP/VA copolymer, and a mixture thereof;

(e) at least 0.5 wt. % to 8 wt. % of at least one polyol chosen from ethylene glycol, propylene glycol, butylene glycol, hexylene glycol, pentylene glycol, diethylene glycol, dipropylene glycol, 1,3 propanediol, polyethylene glycols, caprylyl glycol, diglycerin, glycerin, and a mixture thereof; and

(f) water;

wherein (b) and (a) are in a weight ratio from about 0.1 to about 0.5 ((b)/(a)) and all weight percentages are based on a total weight of the composition.

2. The composition of claim 1 , wherein the composition is not an emulsion.

3. The composition of claim 1 , wherein the composition comprises less than wt. % of a non-ester oil.

4. The composition of claim 1 , wherein the composition comprises less than 1 wt. % of oils.

5. A leave-on hair cosmetic composition comprising:

(a) about 1 to about 4 wt. % of hydroxypropyl guar;

(b) about 0.1 to about 1.8 wt. % of hydroxypropyl guar hydroxypropyltrimonium chloride;

(c) 0.1 to about 4 wt. % of polylquaternium-4;

(d) about 1.2 to about 4 wt. % of at least one polymer selected from VP/dimethylamino ethylmethacrylate copolymer, VP/VA copolymer, and a mixture thereof;

(e) at least 0.5 to about 10 wt. % of at least one polyol chosen from ethylene glycol, propylene glycol, butylene glycol, hexylene glycol, pentylene glycol, diethylene glycol, dipropylene glycol, 1,3 propanediol, polyethylene glycols, caprylyl glycol, diglycerin, glycerin, and a mixture thereof; and

(f) about 70 to about 95 wt. % of water;

wherein (b) and (a) are in a weight ratio from about 0.1 to about 0.5 ((b)/(a)) and all weight percentages are based on a total weight of the composition.

6. The composition of claim 5 , wherein the weight ratio is from about 0.12 to about 0.3.

7. The composition of claim 5 comprising about 1.2 to about 4 wt. % of the VP/dimethylamino ethylmethacrylate copolymer.

8. The composition of claim 5 comprising about 1.2 to about 4 wt. % of the VP/VA copolymer.

9. The composition of claim 5 , wherein the composition is not an emulsion.

10. The composition of claim 5 , wherein the composition comprises less than wt. % of a non-ester oil.

11. A composition consisting of:

(a) about 1 to about 4 wt. % of hydroxypropyl guar;

(b) about 0.1 to about 1.8 wt. % of hydroxypropyl guar hydroxypropyltrimonium chloride;

(c) 0.1 to about 4 wt. % of polylquaternium-4;

(d) about 1.2 to about 4 wt. % of at least one polymer selected from VP/dimethylamino ethylmethacrylate copolymer, VP/VA copolymer, and a mixture thereof;

(e) at least 0.5 to about 10 wt. % of at least one polyol chosen from ethylene glycol, propylene glycol, butylene glycol, hexylene glycol, pentylene glycol, diethylene glycol, dipropylene glycol, 1,3 propanediol, polyethylene glycols, caprylyl glycol, diglycerin, glycerin, and a mixture thereof;

(f) about 70 to about 95 wt. % of water;

(g) less than 5.3 wt. % of additives, preservatives, organic solvents, and mixtures thereof;

wherein (b) and (a) are in a weight ratio from about 0.1 to about 0.5 ((b)/(a)) and all weight percentages are based on a total weight of the composition.

12. A method of treating hair, the method comprising applying the composition of claim 1 to hair.

13. A method for treating hair comprising applying the composition of claim 5 to the hair, and without rinsing the composition from the hair, styling the hair.

14. A method for treating hair comprising applying the composition of claim 11 to the hair, and without rinsing the composition from the hair, styling the hair.
