Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention is capable of imparting good softness and slipperiness to the hair from the time of wetting to the end of drying, and in particular, the softness and slipperiness of the hair after drying are good, The present invention relates to a hair cosmetic having a good moist feeling.

Hair cosmetics are required to have softness and slipperiness for hair from wet to dry and to have a moist feel without being dry even after drying. From these requirements, quaternary ammonium salts such as stearyltrimethylammonium chloride, behenyltrimethylammonium chloride and distearyldimethylammonium chloride have been used as cationic surfactants, but hair that always satisfies these requirements. No cosmetics have been obtained.

In particular, a dilong-chain alkyl quaternary ammonium salt such as distearyldimethylammonium chloride is used for the purpose of improving the softness when wet, but the dryness of the hair after drying is poor and the feel is heavy. There is a problem of becoming. On the other hand, various combinations of oil agents such as a combination of a specific silicone and an oil and fat (Japanese Patent Laid-Open No. 4-108719) are known in order to improve the flexibility, slipperiness and moist feeling after drying. When these additives are used, the stability of the system is affected, so that there is a problem in that the amount of the mixture needs to be adjusted and the stickiness of the hair occurs, and good softness to hair from wet to dry , The smoothness, and the moist feeling were not satisfied at the same time.
