Description

The present invention relates to a novel hair cosmetic composition, and more specifically, it contains a branched alkyl quaternary ammonium salt and a specific long-chain acyl compound and has a low oily feeling. Hair rinse, hair conditioner, hair treatment, hair cream, styling lotion, styling mousse, condimenting mousse with excellent smoothness, flexibility and antistatic effect,
The present invention relates to hair cosmetics such as hair spray.

[Conventional technology]

Conventionally, hair cosmetics such as hair rinses containing a di-linear long-chain alkyl quaternary ammonium salt such as distearyldimethylammonium chloride having two long-chain alkyl groups in a straight-chain form as a main active ingredient have been used. There is.

Of these, hair rinses are soft, smooth, and
Although the purpose is to impart antistatic properties and the like, a sufficient effect in flexibility and smoothness cannot be obtained only with the di-linear long-chain alkyl quaternary ammonium salt. Therefore, in order to improve these drawbacks, it has been common to blend fats and oils such as higher alcohols, glycerides, and liquid paraffin.

In addition, hair cream mainly composed of oils or resins,
Also in styling agents and the like, mono- or di-linear long-chain alkyl quaternary ammonium salts have been used for the purpose of imparting flexibility, smoothness, antistatic properties and the like.

By the way, since the di-linear long-chain alkyl quaternary ammonium salt does not have the ability to stably emulsify and disperse a sufficient amount of oils and fats to exert its effect, it is stable in emulsion systems such as cream rinses. In order to obtain an emulsified and dispersed system, it has been attempted to blend a highly linear mono-linear long-chain alkyl quaternary ammonium salt or a nonionic surfactant. However, since these highly hydrophilic compounds significantly reduce the rinsing effect, there is a drawback that the original rinsing effect of the quaternary ammonium salt and the fats and oils cannot be sufficiently exhibited.

Further, in hair cosmetics containing oil or resin as a main component, conventional mono- or di-linear long-chain alkyl quaternary ammonium salts do not exhibit sufficient effects such as flexibility, smoothness and antistatic property. There was a problem.

Therefore, there has been a demand for the development of a hair cosmetic composition which is excellent in flexibility, smoothness and antistatic effect, and which does not leave oily bubbles even when a large amount of resin or fats and oils are present.

[Means for solving problems]

Under such circumstances, as a result of intensive studies by the present inventors, as a result of substituting a specific branched quaternary ammonium salt for a part or all of the conventional linear long-chain alkyl quaternary ammonium salt, The present invention has been completed by finding that an excellent hair cosmetic composition that overcomes the above-mentioned drawbacks can be obtained by using a long-chain acyl compound and that a good set-retaining ability can be obtained even under high humidity.
