Abstract

A rinse-off type hair cosmetic composition containing the following ingredients: (A) from 1 to 10 wt % of a higher alcohol having from 12 to 28 carbon atoms, (B) a quaternary ammonium salt represented by the following formula (1) or a tertiary amine type compound represented by the following formula (2) or salt thereof,

(C) from 15 to 70 wt % of a polyhydric alcohol, and (D) from 0.01 to 10 wt % of a dimethylpolysiloxane. The content ratio of the ingredient (A) to the ingredient (B) is from 1:1 to 10:1 in terms of molar ratio. As a method for preventing colored hair from fading, the hair cosmetic composition is used before or after shampooing the colored hair. The hair cosmetic composition can inhibit the bleeding of a colorant from colored hair upon shampooing, and is also excellent in the smoothness of the hair upon applying the composition and also upon rinsing it off.

Claims

1. A rinse-off hair cosmetic composition comprising the following ingredients (A), (B), (C), (D) and (E):

(A) from 2-5 wt % of stearyl alcohol N,N-dimethyloctadecyloxy propylamine,

(C) from 25-60 wt % of glycerine,

(D) from 0.01-5 wt % of dimethylpolysiloxane having a viscosity from 10-10,000 mm²/sec,

(E) from 0.01-5 wt % of a polyoxyethylene glycol having a weight average molecular weight from 500,000 to 5,000,000; and

water

wherein a content ratio of said ingredient (A) to said ingredient (B) in the range of from 2;

1 to 4;

1 in terms of molar ratio.

2. The hair cosmetic composition according to claim 1, further comprising, as an ingredient (F), from 0.01 to 1 wt % of a UV absorber.

3. The hair cosmetic composition according to claim 1, further comprising, as an ingredient (G), from 0.01 to 1 wt % of an antioxidant.

4. A method for reducing colored hair from fading, which comprises using a hair cosmetic composition as defined in claim 1 before or after shampooing said colored hair.

5. The hair cosmetic composition according to claim 1, wherein said glycerine reduces the activity of water.
