Abstract

PURPOSE:To provide a hair cosmetic not having viscous and oily touches, imparting a good touch to damaged hair especially even under low humidity, and having an excellent effect for uniformly arranging the tips of the hair and an excellent effect for preventing the damages of the hair such as split hair or cut hair. CONSTITUTION:A hair cosmetic contains the following components (A), (B) and (C) in a [(B)/(C)] weight ratio of 10/1 to 1/10. (A) One kind or more of silicone derivatives, (B) one kind or more of cationic surfactants, and (C) one kind or more of fatty acids each having a 12-40C linear or branched alkyl or alkenyl group.

Description

[Detailed description of the invention]

0001

[Industrial Field of Application] The present invention relates to a hair cosmetic, specifically a hair cosmetic containing a silicone derivative, a cationic surfactant and a specific fatty acid, which provides a good feel to damaged hair, especially under low humidity. The present invention also relates to a hair cosmetic having the effect of curling hair tips and preventing damage to the hair.

0002

[Prior Art] Conventionally, hair cosmetics contain mono- or di-linear long-chain alkyl quaternary ammonium salts or mono- or di-branched long-chain alkyl quaternary ammonium salts in order to improve the feel of the hair. Contains cationic surfactants such as salts. Furthermore, in recent years, in order to obtain even better texture, oils and fats such as higher alcohols, glycerides, and liquid paraffin have been used in combination with such cationic surfactants.

0003

[Problems to be Solved by the Invention] However, these conventional hair cosmetics have the disadvantage that the feel of the hair, that is, the conditioning effect of flexibility, moist feeling, smoothness, and antistatic effect are insufficient. . Therefore, a method of supplementing the moist feeling by using oils and fats has been taken, but this method causes stickiness and oiliness, and is particularly effective at conditioning damaged hair in dry conditions. There was still the problem that there was insufficient capacity. Furthermore, conventional hair cosmetics have not had sufficient effects on curling the ends of hair and preventing damage to the hair.

[0004] Therefore, the object of the present invention is to provide a good feel to damaged hair without stickiness and oiliness, especially under low humidity, and to improve the clumpiness of hair ends and prevent split ends and breakage of hair. An object of the present invention is to provide a hair cosmetic with excellent damage prevention effects.

[0005]

[Means for Solving the Problems] As a result of intensive studies to achieve the above object, the present inventors have found that by using a cationic surfactant together with a silicone derivative and a specific fatty acid, the fatty acid can be applied to the hair. At the same time as the silicone derivative penetrates into the hair, it is adsorbed to the hair surface and not only prevents damage to the hair when washing or brushing, but also has a moisture-regulating effect after being adsorbed and incorporated into the hair, so it retains its moisture even when the hair is dry. It has been found that an excellent hair cosmetic that provides excellent conditioning effects such as moisturizing, flexibility, and smoothness, and is free from stickiness and oiliness can be obtained.

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