Abstract

This invention relates a hair cosmetic composition, which comprises (A) glycine or alanine, (B) an α-hydroxy acid, β-hydroxy acid, 1,2-dicarboxylic acid, 1,3-dicarboxylic acid or aromatic carboxylic acid, and (C) a cationic surfactant. The hair cosmetic composition is excellent in the effect of improving optical or mechanical properties of hair.

Claims

1. A hair cosmetic composition comprising:

(A) alanine;

(B) an acid selected from the group consisting of malic acid, maleic acid and a mixture thereof; and

(C) a cationic surfactant.

2. A hair cosmetic composition according to claim 1, wherein said cationic surfactant (C) is a quaternary ammonium salt represented by the following formula (1):

wherein at least one of R¹, R², R³ and R⁴ represents an alkyl or alkenyl group, which may optionally be substituted by one or more alkoxy, alkenyloxy, alkanoylamino or alkenoylamino groups and has 8 to 28 carbon atoms in total, the remaining one or ones each independently represent a benzyl group, an alkyl or hydroxyalkyl group having 1 to 5 carbon atoms or a polyoxyethylene group having a total added mole number not greater than 10, and Z⁻

represents a halogen ion or an organic anion.

3. A hair cosmetic composition according to claim 1 or 2, further comprising (D) a higher alcohol in a proportion of from 3 to 10 molar times of said component (C).

4. A hair cosmetic composition according to claim 1 or 2, further comprising (E) a silicone.

5. The hair cosmetic composition of claim 1, wherein alanine is containing in an amount of from 0.01 to 20 wt. %.

6. The hair cosmetic composition of claim 5, wherein component (B) is containing in an amount of from 0.01 to 5 wt. %.

7. The hair cosmetic composition of claim 5, wherein component (C) is containing in an amount of from 0.1 to 20 wt. %.

8. A hair cosmetic composition comprising:

(A) glycine

(B) an acid selected from the group consisting of malic acid, maleic acid and a mixture thereof; and

(C) a cationic surfactant.

9. The hair cosmetic composition according to claim 8, wherein said cationic surfactant (C) is a quaternary ammonium salt represented by the following formula (1):

wherein at least one of R¹, R², R³ and R⁴ represents an alkyl or alkenyl group, which may optionally be substituted by one or more alkoxy, alkenyloxy, aklanoyolamino or alkenoylamino groups and has 8 to 28 carbon atoms in total, the remaining one or ones each independently represent a benzyl group, an alkyl or hydroxyalkyl group having 1 to 5 carbon atoms or a polyoxyethylene group having a total added mole number not greater than 10, and Z⁻

represents a halogen ion or an organic anion.

10. The hair cosmetic composition of claim 8, further comprising (D) a higher alcohol in a proportion of from 3 to 10 molar time s of said component (C).

11. The hair cosmetic composition of claim 8, further comprising (E) a silicone.

12. The hair cosmetic composition of claim 8, wherein glycine is containing in an amount of from 0.01 to 20 wt. %.

13. The hair cosmetic composition of claim 8, wherein component (B) is containing in an amount of from 0.01 to 5 wt. %.
