Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic for hair which is suitable for improving or maintaining hair in a smooth and soft state.

[0002]

2. Description of the Related Art Moist, smooth and glossy hair is what gives a person a desirable impression such as neatness and beauty. Therefore, retaining such hair is what everyone wants. Humans have made much effort since ancient times to keep hair in this condition. For example, in ancient times such as the Heian period, care was taken using rice juice and animal and vegetable oils, and in recent years, various hair care cosmetics such as hair treatments, hair rinses, hair creams, and hair oils have been distributed in pharmacies. It is sold for example, and its sales are not small. In such hair cosmetics, a moist feeling is embodied by a moisturizing component such as a cationic surfactant or a polyhydric alcohol, and smoothness and luster are embodied by an oil component such as silicone. However, such a method has a poor yield in a cleaning agent such as a shampoo, and also in other hair cosmetics, such a method certainly improves the moist feeling and glossiness remarkably. However, in recent years, the frequency of using hair dyes and the frequency of applying cold permanents have been increasing, and further improvements have been desired. That is, a means for further improving the moist feeling, smoothness, and luster of the hair has been desired.

On the other hand, a quaternary amino acid is an amino acid having a quaternary amino group as an amino group, which is known to have an excellent affinity for the skin, but has a moist feeling and smoothness to hair. It was not known at all that it had an effect of improving the glossiness and that the effect was further synergistically increased by combination with cationic cellulose. In addition, it has not been known at all that a cosmetic is contained in combination with at least one selected from quaternary amino acids and salts thereof and cationic cellulose.

[0004]

SUMMARY OF THE INVENTION The present invention has been made under such circumstances, and it is another object of the present invention to provide means for improving the smoothness and smoothness of hair.

[0005]

In view of the above circumstances, the present inventors have conducted intensive studies in search of means for further improving the moist, smooth, and glossy feeling of hair, and as a result, have been selected from quaternary amino acids and salts thereof. The present inventors have found that a cosmetic for hair, characterized in that it contains at least one of the above and a cationic cellulose derivative, has such properties and completed the invention. Hereinafter, the present invention will be described in detail focusing on embodiments.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION (1) One or more quaternary amino acids and salts thereof used in the present invention A quaternary amino acid used as an essential component in the present invention has four alkyl groups or an alkyl group having a substituent. Means an amino acid having a quaternary ammonium ion as an amino group, and examples thereof include trimethylglycine, N, N, N-trimethylalanine, N, N, N-trimethylglutamic acid, and triethylglycine. These are all known compounds, their production methods are already known, and many of them are already commercially available and readily available. A particularly preferred commercial product is trimethylglycine sold by Asahi Foods under the name of Aminocoat. In addition, such quaternary amino acids may be used alone or in combination of two or more. These quaternary amino acids give the hair a moist feeling, protect the hair from damage, and also have the effect of improving the effect of the glossy component.

(2) Cationic cellulose derivative used in the present invention The cationic cellulose derivative used as an essential component in the present invention is secondary, tertiary or tertiary via a free hydroxyl group of cellulose via a hydroxyethyl group or a hydroxypropyl group. ,
Quaternary ammonium groups and pyridinium groups are introduced. Among them, hydroxyethylcellulose hydroxypropyltrimethylammonium chloride ether and the like having a quaternary ammonium group introduced are used as a raw material for cosmetics. preferable. Such raw materials are, for example, Cathin HC-100, HC-200, LC-100, LC-C manufactured by Toho Chemical Co., Ltd.
200, Leoguard G, Leoguard GP, Leoguard KGP, Leoguard MGP, Leoguard MLP, etc., which are already commercially available, are not a few, and these can also be used. Particularly preferred among commercially available ones are Katinal LC-200.
It is. In addition, such a cationic cellulose derivative can be used alone or in combination of two or more. These cationic cellulose derivatives not only give the hair a remarkable moist feeling and smoothness, but also have the effect of improving the effect of the glossy component.

(3) Cosmetic for hair of the present invention The cosmetic for hair of the present invention is characterized by containing one or more selected from quaternary amino acids and salts thereof and a cationic cellulose derivative. . Specific examples of preparations of hair cosmetics include shampoos, rinses, treatments, hair creams, hair lotions, hair nourishes, hair dyes, polishes, and the like. The preferred content of one or more selected from quaternary amino acids and salts thereof in the cosmetic of the present invention is 0.001 to 5% by weight, and more preferably 0.01 to 3% by weight. This is because if the amount is too small, the effect may not be sufficiently exhibited, and if the amount is too large, the effect of addition may plateau. Further, the preferred content of the cationic cellulose derivative is 0.0
It is 1 to 5% by weight, more preferably 0.05 to 3% by weight. This is because if the amount is too small, the effect may not be sufficiently exhibited, and if the amount is too large, the effect of addition may plateau. In addition to these essential components, the cosmetic of the present invention can contain optional components usually used in cosmetics for hair. Such optional components include, for example,
Hydrocarbons such as petrolatum and microcrystalline wax, esters such as jojoba oil and gay wax, tallow,
Triglycerides such as olive oil, higher alcohols such as cetanol and oleyl alcohol, stearic acid,
Fatty acids such as oleic acid, polyhydric alcohols such as glycerin and 1,3-butanediol, nonionic surfactants, anionic surfactants, cationic surfactants, amphoteric surfactants, thickening of ethanol, carbopol, etc. Agents, preservatives, ultraviolet absorbers, antioxidants, pigments, hair growth ingredients, hair growth promoters,
Polishing agents, powders and the like can be preferably exemplified. Among them,
As an optional component, it is preferable to include a branched ester of lanolin fatty acid or a collagen hydrolyzate and / or a derivative thereof. Fatty acid isopropyl ester (Yofco FE-IPR) and the like can be exemplified, and the content thereof is preferably 0.1 to 10% by weight. Further, as the collagen hydrolyzate and / or a derivative thereof, Promois W-32, W- 32P, W-32R, W-52, W-5
Commercial products such as 2R (manufactured by Seiwa Kasei) can be preferably exemplified.
A particularly preferred collagen hydrolyzate and / or derivative thereof contains Promois W-32R and Promois W-52Q in a weight ratio of 2: 1 to 1: 2, and the content is 0.1%. It is preferably from 01 to 2% by weight.
The cosmetic for hair of the present invention can be produced by treating these essential components and optional components by an ordinary method.
