Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention contains a hair cosmetic composition, more specifically, a silicone derivative, a cationic surfactant and a specific fatty acid, and imparts a good feel to damaged hair, particularly under low humidity. The present invention also relates to a hair cosmetic composition having a hair tip gathering effect and a hair damage preventing effect.

[0002]

2. Description of the Related Art Conventionally, in order to improve the feel of hair, hair cosmetics have been known as mono- or di-linear long-chain alkyl quaternary ammonium salts and mono- or di-branched long-chain alkyl quaternary ammoniums. A cationic surfactant such as salt is blended. In addition, in recent years, in order to obtain a better feeling, it has been practiced to use oils and fats such as higher alcohols, glycerides and liquid paraffin in combination with such cationic surfactants.

[0003]

However, these conventional hair cosmetics have a drawback that the feel of the hair, that is, the conditioning effect such as softness, moisturizing feeling, smoothness and antistatic effect is insufficient. . Therefore, in regard to moist feeling, a method of supplementing by using oils and fats together is taken, but this method is sticky and oily, especially for dry hair conditioning effect on damaged hair Was still insufficient. Furthermore, the conventional hair cosmetics have not been sufficient in the effect of gathering hair tips and the effect of preventing damage to hair.

[0004] Therefore, the object of the present invention is to have no sticky feeling and no greasiness, to impart a good feeling to damaged hair, especially at low humidity, and to provide a hair bunching effect and split ends or broken hair. An object of the present invention is to provide a hair cosmetic composition having an excellent effect of preventing damage such as

[0005]

Means for Solving the Problems As a result of intensive studies to achieve the above object, the present inventors have found that the fatty acid can be obtained by using a silicone derivative and a specific fatty acid in combination with a cationic surfactant. The silicone derivative is adsorbed on the hair surface at the same time as it penetrates into the hair to prevent damage to the hair at the time of washing and brushing, and the moisture control effect after being adsorbed and taken up by the hair causes the hair to be dried. It has been found that an excellent hair cosmetic composition which gives excellent conditioning effects such as moisturizing feeling, flexibility and smoothness, and is free of stickiness and oiliness can be obtained.

The present invention was made based on the above findings, and contains the following components (A), (B) and (C),
