Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a hair cosmetic composition, and more specifically, it imparts a good feeling such as moisturizing feeling and dry feeling to hair, and also has an effect of suppressing dander on the scalp to suppress dandruff. , Hair conditioners, hair conditioners, hair treatments, and other hair cosmetics.

[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.

On the other hand, a silicone derivative represented by a polymer of dimethylpolysiloxane is smooth and excellent in lubricity as compared with higher alcohols, glycerides, liquid paraffin, esters, etc., and has a smooth feel and gloss on hair. It is known to give and is used in many hair cosmetics.

However, the silicone derivative must be added in a large amount to the hair cosmetic composition in order to ensure its effects and performances, which is disadvantageous in that it is sticky. In addition, a polymer silicone that can give a particularly excellent dry feeling has a drawback that it has a peculiar hardness, has a firm feeling, and lacks flexibility.

Further, JP-A-57-50911 discloses a hair rinse composition containing quaternary ammonium salt and cholesterol for the purpose of imparting gloss and smoothness to hair.

However, this composition is still insufficient in the effect of suppressing stickiness of the hair and giving a good feeling of moisturizing and smoothness, and also suppressing the bulkiness of the scalp and imparting a refreshing feeling which is not sticky. It wasn't something.

Therefore, there is no sticky feeling and no oiliness,
It has been desired to develop a hair cosmetic composition that is excellent in conditioning effects such as moisturizing feeling, dry feeling, and softness, and that further suppresses bulkiness and suppresses dandruff without sticking to the scalp.
