Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a hair which is excellent in hair-keeping effect, has good elongation at the time of application to hair, has very little stickiness, and has excellent re-shaping properties and excellent storage stability after application. Related to cosmetics.

[0002]

2. Description of the Related Art Conventionally, hair gels, hair creams, hair foams, hair lotions and the like have been used as hair cosmetics for hair styling. These hair cosmetics are generally blended as a hair styling component by solubilizing, dispersing or emulsifying a liquid oil such as silicone oil, ester oil or hydrocarbon oil, or a polymer compound having a film forming ability. However, liquid oils typified by silicone oils have poor and poor set retention (cohesion) on hair. In addition, a polymer compound having a film-forming ability is excellent in set retention (cohesion), but it has stiffness and lacks flexibility, and if the formed film is broken, the hair is re-shaped. There is a drawback that it is difficult. In addition, when the hair cosmetic is viscous, it has the effect of bundling adjacent hairs when applied to the hair and improves the set retention (unity), but feels sticky at the time of application and is applied to the entire hair There was a drawback that it was difficult to do.

[0003]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail.

The carboxyl group-containing thickening polymer compound (A) used in the present invention becomes water-soluble by neutralizing the carboxyl group with an alkaline substance, and increases the viscosity of an aqueous system. Include, for example, carboxyvinyl polymer (trade name: CARBOPOL,
B. F. GOODRICH), acrylic acid / alkyl methacrylate copolymer (trade name: PEMULEN,
B. F. GOODRICH), alkyl acrylate / alkyl methacrylate polyoxyethylene ester copolymer (trade name: ACULYN, ISP) alkyl acrylate / alkyl itaconate polyoxyethylene ester copolymer (trade name: Structure, NSC)
Co., Ltd.), methyl vinyl ether / maleic anhydride / decadiene copolymer (trade names: STABILEZE, ISP)
And the like). Among the above copolymers, acrylic acid / alkyl methacrylate copolymer (trade name: PEMUL)
EN, B.E. F. (GOODRICH) is particularly excellent in storage stability.

The above-mentioned carboxyl group-containing thickening polymer compounds can be used alone or in combination of two or more. The compounding amount is 0 to the total amount of the hair cosmetic composition. 0.01 to 2.0% by mass (hereinafter simply referred to as%
Is abbreviated), and more preferably 0.05 to 1.0.
%. When the content is 0.01% to 2.0%, a preferable viscosity in use is easily obtained, the spread at the time of application is good, and a desirable hair keeping effect is easily obtained.

The alkaline substance (B) used in the present invention includes, for example, alkanolamines such as disopropanolamine and triethanolamine, ammonia, potassium hydroxide, sodium hydroxide, and basic amino acids (lysine, Arginine), basic polypeptides and the like. These alkaline substances are
It is used as a neutralizing agent for the carboxyl group-containing thickening polymer compound of the component (A). The amount of the alkaline substance
It is adjusted so that the carboxyl group of the component (A) is neutralized by 50 to 100% equivalent.

The oily agent which is in the form of a paste at room temperature of the component (C) in the present invention includes, for example, lanolin, trilanolin fatty acid glyceryl, soft lanolin fatty acid, vaseline, branched or hydroxylated fatty acid cholesteryl, dipentaerythritol fatty acid ester (hexaoxyerythritol).

These are paste-like (semi-solid) oils at room temperature and have a melting point at a temperature exceeding the range of room temperature (15 to 25 ° C), and are distinguished from liquid oils and solid fats and oils in that they do not completely solidify in this range. It is an oil agent to be used. Among the above paste-like oils, use of lanolin, petrolatum, monohydroxystearic acid-hardened castor oil, tri (capryl / caprin / myristin / stearic acid) glyceride, and dipentaerythritol fatty acid ester are particularly excellent in terms of hair redressing properties. .

A substance that is liquid at room temperature with a melting point of less than 20 ° C. is selected and used. Among oils that are liquid at room temperature, ester oils are superior to other liquid oils in terms of hair styling retention and non-stickiness, and among them, particularly excellent effects are produced when esters of α-hydroxy acids and alcohols are used. . Esters of α-hydroxy acid and alcohol are esters of α-hydroxy acid and alcohol, α-hydroxycarboxylic acid such as malic acid, citric acid, tartaric acid, lactic acid, 2-ethyl-hexanoic acid, ethanol,

The polyhydric alcohol of component (E) in the present invention can be used alone or as a mixture of two or more, and the amount thereof is based on the total amount of the hair cosmetic composition. 0.05 to 20.0% is more preferable, and more preferably 0.1 to 10.0%. When the blending amount of the polyhydric alcohol is less than 0.05%, it is difficult to improve the hair re-dressing property, and the blending amount is 20.0%.
When the ratio exceeds, a sticky feeling may be caused.

In the present invention, if a nonionic surfactant is further blended as the component (F), the storage stability is improved.
Examples of the nonionic surfactant (F) in the present invention include sorbitan fatty acid ester, glycerin fatty acid ester, polyglycerin fatty acid ester, propylene glycol fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene sorbite fatty acid ester, Polyoxyethylene glycerin fatty acid ester, polyethylene glycol fatty acid ester,

It was left in a high-temperature room at 45 ° C. for 6 hours and completely dried. After drying, the rod was removed and the apparent length (L) of the hair bundle was measured. Next, the hair bundle was hung in a thermo-hygrostat at a temperature of 25 ° C. and a humidity of 90%, taken out after 30 minutes, and the apparent length (L 0) of the hair bundle was measured again.

The hair styling retention effect was determined by the following equation. Hairdressing holding power (%) = (15−L0) ÷ (15−L) × 1
Therefore, the closer this value is to 100, the higher the hair styling retention effect.

The evaluation criteria are as follows. ◎: Very good Hair holding power of 80% or more ○: Good Hair holding power of 50% or more and less than 80% △: Slightly poor Hair holding power of 30% or more and less than 50% ×: Poor Hair holding power of less than 30%

Thereafter, the subject himself / herself carried out a sensory evaluation on stretchability, non-stickiness, and re-shaping property when applying the hair cosmetic. The evaluation criteria are as follows.

◎: Very good The number of subjects who answered good is 18 or more ○: Good The number of subjects who answered good was 12 or more and less than 18 △: Somewhat bad The number of subjects who answered good was 8 Not less than 12 and ×: poor The number of subjects who answered good was less than 8

(3) Storage stability A hair cosmetic sample was filled in a transparent container, stored in a thermostat kept at 40 ° C., and the state (viscosity and appearance) of the sample after three months was evaluated.

The evaluation criteria are as follows. ：: Change in viscosity is within ± 10% ○: Change in viscosity is ± 10 or more and less than 20% Δ: Change in viscosity is ± 20 or more and less than 30% ×: Change in viscosity is ± 30% or more, or separation
