Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention has no stickiness,
Improves hair cohesion and provides excellent combability for hair,
It relates to a hair conditioning composition which imparts luster.

[0002]

2. Description of the Related Art With the recent increase in awareness of hair care among consumers, demands for conditioning effects of hair cosmetics have been diversified. In particular, one of the important demands is to improve the looseness of hair, poor combability, and poor luster due to damage to hair.

Conventionally, hair conditioning compositions have been used by solubilizing, emulsifying and dissolving oil components such as silicone oils, ester oils and hydrocarbon oils for the purpose of imparting excellent luster to hair. In particular, silicone oil is excellent in non-stickiness and has been widely used in recent years. However, while oils represented by silicone oils alone give excellent luster to hair, their ability to improve the cohesion of hair is poor and insufficient.

Further, various polymer compounds are used in hair conditioning compositions for the purpose of improving the cohesion of hair. In particular, nitrogen atom-containing polymer compounds such as quaternized vinylpyrrolidone / dimethylaminoethyl methacrylate and cationized cellulose are widely used. However, these polymer compounds had poor combability and were sticky due to their high hygroscopicity.

In order to solve these drawbacks, as a hair cosmetic having a conditioning function, JP-A-2-2314 has been proposed.
No. 11, JP-A-5-148123, and JP-A-6-
JP-A-263620 discloses the use of a protein derivative, a silicone derivative, and an amino acid derivative in a hair cosmetic composition, but they are inferior in gloss and are not satisfactory.

[0006]

SUMMARY OF THE INVENTION In view of such a situation, an object of the present invention is to improve tackiness of hair without stickiness, and to impart excellent combability and luster to hair.
