Abstract

PURPOSE:The titled composition, containing an alkyl ester salt of a mono N- long chain acyl basic amino acid, a straight chain saturated alcohol, a sorbitan ester of a fatty acid, etc., capable of improving the luster and brushability of hair, and having improved dispersion stability. CONSTITUTION:A hair cosmetic composition containing 0.1-5wt% alkyl ester salt of a mono N-long chain acyl basic amino acid, e.g. lauroyllysine methyl ester hydrochloride, 0.7-5wt% 14-22C straight chain saturated alcohol, 0.1- 2wt% sorbitan ester of a fatty acid, e.g. sorbitan monooleate, 0.1-2wt% polyglycerol ester of a fatty acid, e.g. diglycerol monostearate, and 0.5-10wt% polyhydric alcohol or an alkylene oxide adduct derivative thereof, e.g. propylene glycol. The above-mentioned cosmetic in the form of a hair lotion, hair conditioner, hair rinse, etc. is applied to the hair.

Description

[Detailed description of the invention] The present invention relates to a hair cosmetic composition.

In recent years, hair has become extremely susceptible to damage due to the spread of hair dyes, hair dyes, hair dyes, and the like.

Consumers also say that their hair is dry and restless.
There are many problems with lack of shine and poor brushability. Therefore, hair cosmetics that moisturize and soothe hair and improve shine and brushability are desired.

Furthermore, since hair comes into direct contact with the skin of the nape of the neck and must be touched with hands when caring for it, a sticky, raw texture is strongly disliked. Therefore, a stable emulsion system without stickiness is also a desirable condition for hair cosmetics.

However, among conventional hair cosmetics, there is no one that can satisfy all of the various properties listed in "jl". In other words, because conventional hair cosmetics contain oily components, many of them end up with a greasy, sticky finish. On the other hand, attempts have been made to reduce the amount of oil contained in hair cosmetics to achieve a light, saline-like finish to the hair, but if it is as low as 1'81' or 1', it becomes sticky. However, the gloss and brushability of the hair are significantly reduced.

An object of the present invention is to provide a glue-like hair cosmetic composition with good dispersion stability that can moisturize hair, improve glossability, reduce stickiness, and make hair manageable. It is.

To provide a hair make-up composition containing a polyglycerin fat content costel of 2% by weight and a polyhydric alcohol or an alkylene oxide addition derivative thereof of 05 to 10% by weight.

Mono N, which is the first essential component of set 1 of this expression 19]
- As a basic amino acid constituting a long-chain acyl basic amino acid lower alkyl ester salt.

Mention may be made, for example, of the natural amino acids of ornitene, lysine and arginine. Furthermore, synthetic amino acids such as α,γ-Vaminobutyric acid can be used as well. These may be optically active or racemic.

The acyl constituting the mono N-long chain acyl basic amino acid lower alkyl ester salt is a saturated or unsaturated fatty acid residue having 8 to 22 carbon atoms. These may be natural or synthetic. Examples include lawaloyl group, myristyl group, valmitoyl group, and stearoyl group.

Mono N-long chain acyl basic lower alkyl ester salts include inorganic sensitive salts such as hydrochloride or <2<
p-Toluenesulfone brewed.

Organic acid salts such as fatty acid salts, electroconductive amino acid salts, and pyroglutamic acid salts can be employed. Among the stiff salts, hydrochloride and L- or DL-pyrrolidonecarzanate are preferred.

In order for the composition of this invention to be uniformly adsorbed on the hair surface and to exist as a stable dispersion composition to maintain commercial value, in addition to the above-mentioned components, sorbitan fatty acid ester,
It is essential to contain three components: polyglycerol fatty acid ester and poly(+Ij alcohol or its alkylene oxide addition derivative).

The fats constituting the sorbitan fatty acid ester, which is the third essential component of the composition of the present invention, are saturated fatty acids and unsaturated fatty acids with different side chains2).

Preferred fatty acids are caprylic acid and capric acid.
