Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a hair cosmetic composition, and more specifically, to a hair having a good feel, a hair damage suppressing effect, and a scalp whitening preventing dandruff suppressing effect. Hair rinse with less squeaky feeling after rinsing,
The present invention relates to hair cosmetics such as hair conditioners and hair treatments.

[0002]

2. Description of the Related Art Conventionally, the problems to be solved by the invention
For hair cosmetics, cationic surfactants such as mono- or di-linear long-chain alkyl quaternary ammonium salts and mono- or di-branched long-chain alkyl quaternary ammonium salts for the purpose of improving the feel of hair. Has been blended. In recent years,
For the purpose of imparting suppleness and moisturizing feel to hair, it has been practiced to use oils and fats such as higher alcohols, glycerides, liquid paraffins and ester oils in combination with these cationic surfactants.

However, these conventional hair cosmetics have a drawback in that the feel of the hair, that is, the conditioning effect such as flexibility, moisturizing feeling, smoothness and antistatic effect, is insufficient.

Therefore, for the purpose of improving the feel of hair,
Although it has been attempted to increase the blending amount of the oil agent, this also has a drawback that a residual feeling of the oil agent, that is, an oily sticky feeling is generated, and a refreshing feeling is not obtained even on the scalp, which is a cause of itching. Was becoming. Furthermore, the effect of preventing damage to hair was not sufficient.

On the other hand, Japanese Patent Laid-Open No. 57-50911 discloses a fourth method for imparting gloss and smoothness to hair.
A hair cosmetic composition containing a primary ammonium salt and cholesterol is disclosed, and JP-A-61-249912.
The publication discloses a cationic surfactant composition containing a solvent such as a cationic surfactant, cholesterins and alkanols.

[0006] However, although these cosmetics also improve the feel of hair, they are not sufficiently effective in preventing damage to the hair, and they are not effective in preventing whitening of the scalp.
The effect of suppressing dandruff was inferior.

Therefore, it has no sticky feeling and no greasiness, has an excellent conditioning effect, has a sufficient hair damage preventing effect, and has an effect of preventing whitening of the scalp and suppressing dandruff. Hair cosmetics in which mono- or di-long-chain alkyl quaternary ammonium salt type cationic surfactant, cholesterol derivative and dialkylene glycol monoalkyl ether are combined (Japanese Patent Application No. 4-11
No. 1558) has been proposed. However, this hair cosmetic composition has a drawback that it has a squeaky feeling particularly after rinsing the hair.

Therefore, there is no sticky feeling and no greasiness,
It has excellent conditioning effects such as moisturizing effect, and also has sufficient hair damage prevention effect.It also has the effect of suppressing bulkiness, preventing whitening, and suppressing dandruff without sticking to the scalp. There has been a demand for the development of a hair cosmetic having less squeaky feeling after rinsing.

[0009]

Under such circumstances, the inventors of the present invention have conducted extensive studies and as a result, have found that mono- or di-long-chain alkyl quaternary ammonium salt type cationic surfactants are used.
