BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic composition, and more particularly to a conditioning effect for hair, which maintains gloss, luster, good finger passage to hair and a flexible finish over a long period of time. And a hair cosmetic composition that imparts

[0002]

2. Description of the Related Art Normal shampoos not only remove dirt from the hair, but also remove oils that protect the surface of the hair, thereby losing the flexibility of the hair and, as a result, the hair becomes harder. , It gives a stiff feel. For this reason, a hair cosmetic composition containing a cationic surfactant as a main component and an oil such as a higher alcohol, a protein, or a water-soluble polymer to improve the feel of the hair and enhance the conditioning effect has been tried as a hair cosmetic composition. And has been used. However, the finish, feel, and conditioning effect are still insufficient, and remain as difficult problems to solve.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to improve the above-mentioned conventional problems, that is, to provide a hair cosmetic composition having good finish, feel, conditioning effect and good hair style retention. And

[0004]

Means for Solving the Problems The hair cosmetic composition of the present invention has the following features to solve the above problems.
0.01% by weight or more and 2% by weight of one or more amphoteric polymers
Hereinafter, 0.1% by weight or more and 5.0% by weight or less of one or more selected from lanolin and derivatives thereof, and 0.1% or more and 5.0% by weight or less of one or more kinds of wax other than lanolin. A hair cosmetic composition.

[0005] With such a constitution, finger passing through the hair is good, a supple and flexible finish feeling is maintained for a long time, a conditioning effect can be imparted to the hair, the retention of the hair style is good, and the primary stimulus is obtained. It can be a hair cosmetic composition having no sex.

Further, by blending a cationic surfactant as described in claim 2, the stability of the product can be further improved, and the conditioning effect can be further improved by a synergistic effect with the other three essential components. Can be improved.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION In the hair cosmetic composition of the present invention, the amphoteric polymer forms a soft film on the entire hair, thereby imparting excellent antistatic effect and conditioning effect. Further, in the present invention, a synergistic effect with other essential components gives a soft and smooth finish feeling, and furthermore, a long-lasting effect is given by covering the gloss and luster imparted to the hair with a soft film. .

Examples of such amphoteric polymers include hydroxypropyl acrylate / butylaminoethyl methacrylate / octylamide acrylate copolymer, hydroxypropyl acrylate / butylaminoethyl methacrylate / octylacrylamide acrylate copolymer, methacryloyl Ethyldimethylbetaine / methacryloylethyltrimethylammonium chloride / 2-hydroxyethyl methacrylate copolymer, N-methacryloyloxyethyl N, N-dimethylammonium / α-N-methylcarboxybetaine / alkyl methacrylate copolymer, N- Methacryloylethyl N, N-dimethylammonium / α-N-dimethylcarboxybetaine / stearyl methacrylate copolymer, N-methacryloylethyl N, N-dimethyla Examples thereof include ammonium, α-N-methylcarboxybetaine and butyl methacrylate copolymer, and acrylamide / acrylic acid / dimethyldiallylammonium chloride copolymer liquid.

These amphoteric polymers can be used alone or in combination of two or more, if necessary. The compounding amount is 0.01% by weight or more and 2% by weight as a solid content in the whole composition. If the amount is less than 0.01% by weight, it is not possible to sufficiently impart a smooth feel and finger-like goodness to the hair, while if it exceeds 2% by weight, the stability of the system and the conditioning effect may be impaired. The optimum range of the amount is from 0.1% by weight to 1% by weight.

[0010] Anionic polymers other than amphoteric polymers and nonionic polymers have insufficient antistatic effect and conditioning effect, and cationic polymers are complex when the liquidity of the hair cosmetic composition is anionic. This is unsuitable because the antistatic effect and the conditioning effect may be reduced and the stability of the agent may be poor.

In the present invention, lanolin and the lanolin derivative have a function of imparting water retention and improving the moisturizing effect and flexibility of hair. In the present invention, a supple and flexible finish is imparted by a synergistic effect with other essential components. Such lanolin and lanolin derivatives include polyoxyethylene lanolin alcohol, soft lanolin fatty acid, hard lanolin fatty acid,
Reduced lanolin, hard lanolin, lanolin acetate, liquid lanolin, adsorption formed lanolin, lanolin acetate liquid, polyoxyethylene lanolin, lanolin alcohol, lanolin alcohol phosphate, lanolin fatty acid ester,
Lanolin pentaerythol ester and the like can be mentioned.

These lanolins and lanolin derivatives can be used alone or in combination of two or more as necessary. The compounding amount is 0.1% by weight or more and 5% by weight. If the amount is less than 0.1% by weight, a supple and flexible finish cannot be imparted to the hair, while if it exceeds 5% by weight, the conditioning effect such as an increased finish feeling may be impaired. The optimum range of the amount is from 0.5% by weight to 3% by weight.

[0013] The wax other than lanolin and the lanolin derivative used in the present invention has a function of imparting gloss and luster to hair, but further has a synergistic effect with other essential components.
Gives better gloss and luster, and gives a supple and flexible finish.

As such a wax, a natural wax is desirable, such as whale wax, shellac, beeswax, bleached beeswax, carnauba wax, candelilla wax, wood wax, white wax, jojoba oil, montan wax, rice wax and the like. Can be

These waxes can be used alone or in combination of two or more as necessary. The compounding amount is 0.1% by weight or more and 5% by weight. If the content is less than 0.1% by weight, a glossy and glossy finish cannot be sufficiently imparted, while if it exceeds 5% by weight, the conditioning effect such as an increase in the finish is impaired, and furthermore, the product is damaged. May impair the stability. The optimum range of the amount is from 0.5% by weight to 3% by weight.

The above 3 essential for the hair cosmetic composition of the present invention.
By blending a cationic surfactant in addition to the components, the stability of the product can be further improved, and the conditioning effect can be improved by a synergistic effect with the other three essential components.

Examples of such a cationic surfactant include alkyl quaternary ammonium salts such as cetyltrimethylammonium bromide and stearyltrimethylammonium chloride.
It is preferable that the content be not more than weight%. If the amount is less than 0.1% by weight, the effect of the addition of the cationic surfactant is not sufficient. On the other hand, if the amount exceeds 10% by weight, the effect of the addition of the cationic surfactant hardly increases.

Further, the hair cosmetic composition of the present invention may contain an emulsifier, an emulsifier, a viscosity adjuster, a pH adjuster, a hair protectant, etc. in a quantitative and qualitative range according to the purpose, without impairing the effects of the present invention. The following components are possible.

Examples of the emulsifier include a nonionic surfactant represented by a polyoxyethylene addition surfactant, an anionic surfactant represented by a higher alcohol sulfate, and a quaternary ammonium salt of a higher alcohol. And amphoteric surfactants represented by coconut fatty acid amidopropyl betaine. Examples of the emulsification aid include a polyhydric alcohol ester type surfactant represented by a fatty acid glycerin ester and an alkylene oxide addition type surfactant represented by a Pluronic type surfactant.

Examples of the viscosity modifier include natural water-soluble polymers such as carrageenan and guar gum, and semi-synthetic water-soluble polymers such as methylcellulose and hydroxyethylcellulose, such as carboxyvinyl polymer or polyacrylic acid, which are synthetic water-soluble polymers. Sodium and the like.

Acids such as citric acid and lactic acid and salts thereof, and alkali components such as sodium hydroxide and triethanolamine can be used as the pH adjuster. Examples of the hair protecting agent include vitamins, various amino acids, polypeptides and derivatives thereof.

In addition to these, oils and fats, hydrocarbons,
Other components that are usually blended into cosmetics, such as higher fatty acids, polyhydric alcohols, various esters, sugars, UV inhibitors, antioxidants, preservatives / bactericides, and fragrances, are also included as long as they do not interfere with the effects of the present invention. can do.

The hair cosmetic composition of the present invention can be produced according to a usual method using the above-mentioned components. At that time, as long as the effects of the present invention are not hindered, adjustment can be made in a quantitative and qualitative range, and the form is not particularly limited.
For example, the present invention can be implemented in various forms such as a liquid, an emulsion, a cream, a gel, a mousse, and a paste. Also, it can be mixed with various propellants such as liquefied petroleum gas, nitrogen gas, carbon dioxide gas, dimethyl ether and the like to obtain an aerosol product such as hair mousse or hair spray.
