Abstract

A hair cosmetic contains (A) a side chain amino-modified organopolysiloxane having long chain alkyl at both ends at 0.01 to 15 weight %, (B) one type or two or more types of cationic surfactant selected from tertiary amine compounds at 0.1 to 15 weight %, (C) a higher alcohol having 12 to 28 carbon atoms and one hydroxy group at 0.1 to 20 weight %, (D) a polydimethylsiloxane at 0.01 to 15 weight %, and (E) water, the side chain amino-modified organopolysiloxane having long chain alkyl at both ends having a nitrogen atom content of 0.31 to 2 weight %.

Claims

1. A hair cosmetic components (A) to (E):

(A) 0.01 to 15 weight % of a side chain amino-modified organopolysiloxane having long chain alkyl at both ends, represented by formula (1);

(R¹R²₂)SiO—

(R²₂SiO)_x—

(R²R³SiO)_y—

Si(R¹R²₂) 

 

(1)

wherein, in formula (1), R¹ represents a straight chain or branched alkyl group having 12 to 50 carbon atoms, R² represents a substituted or unsubstituted monovalent hydrocarbon group having 1 to 6 carbon atoms, R³ represents a 3-aminopropyl group or an N-(2-aminoethyl)-3-aminopropyl group, x is 1 to 2000, and y is an integer of 1 to 100;

(B) 0.1 to 15 weight % of a cationic surfactant comprising at least one tertiary amine compound;

(D) 0.01 to 15 weight % of a polydimethylsiloxane; and

(E) water,

wherein a nitrogen atom content of the side chain amino-modified organopolysiloxane having long chain alkyl at both ends is 0.31 to 2 weight %, and

wherein a weight ratio of the component (A) to the component (D), (A)/(D), is 0.01 to 2.

3. The hair cosmetic according to claim 1, wherein in the formula (1), the ratio of y to x, y/x, is 0.003 to 0.1.

4. The hair cosmetic according to claim 1, wherein in the formula (1), R¹ is a straight chain alkyl group having 12 to 50 carbon atoms.

5. The hair cosmetic according to claim 1, wherein in the formula (1), R¹ is a branched alkyl group having 12 to 50 carbon atoms.

6. The hair cosmetic according to claim 1, wherein the component (B) is at least one of a hydroxy ether alkylamine and a salt thereof, an ether amine and a salt thereof, and an alkylamidoamine and a salt thereof.

7. The hair cosmetic according to claim 1, further comprising component (F):

(F) an organic solvent selected from the group consisting of

(f1) a compound represented by formula (2);

8. The hair cosmetic according to claim 1, further comprising (G) an organic acid.
