DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic composition which has a hair styling property and a good feel without oiliness, and maintains the feel.

[0002]

2. Description of the Related Art An amphiphilic polymer has a characteristic that it has a viscosity suitable for hair styling in an aqueous solution state, and has a hair styling style because it forms a film after drying. Therefore, it is excellent as a hair styling base such as gel for hair and cream. However, this feel is not desirable, and has drawbacks such as no squeak, no dry feel and no moist feeling. Therefore, it is necessary to add a feel improving agent. When a liquid oil such as ester oil or liquid paraffin is blended, creaking is eliminated, but an oily feeling is produced. On the other hand, when the powder is blended, the stain can be improved, and a very smooth good feeling without oiliness can be imparted. However, this feel was not as persistent.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a hair cosmetic composition which has good hair styling properties, good hair feel, and maintains such good feel.

[0004]

Means for Solving the Problems The present inventor blended a powder with an amphiphilic polymer, and added a paste-like oil at room temperature to the powder so that the powder had no oily feeling. It has been found that the powder can be prevented from falling due to the appropriate adhesive force of the oil agent without impairing the feel, and that this good feel is maintained for a long time.

That is, the present invention relates to (A) a (meth) acrylic acid / alkyl (meth) acrylate copolymer, a water-soluble cellulose derivative quaternary ammonium ether, acrylic acid / methacrylic acid / alkyl acrylate / methacrylic acid. 0.1 to 10% by weight of an amphiphilic polymer selected from a polyoxyethylene alkyl ether ester copolymer of alkyl / methacrylic acid / methacrylic acid and an alkyl acrylate copolymer emulsion; 2
0.1 to 10% by weight of 0 μm spherical powder, (C) pasty at room temperature selected from lanolin, glyceryl trilanoline fatty acid, soft lanolin fatty acid, petrolatum, branched or hydroxylated fatty acid cholesteryl and dipentaerythritol fatty acid ester An object of the present invention is to provide a hairdressing cosmetic composition containing 0.1 to 10% by weight of an oil agent and not washed off with water.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The (A) amphiphilic polymer used in the present invention is a polymer having an affinity for both an aqueous medium and an oily medium and having a film-forming property, and (meth) acrylic. Acid / alkyl (meth) acrylate copolymers (eg, acrylic acid / alkyl methacrylate copolymers (Carbopol 1382, Pemulen TR-1, Pemulen TR-2 (manufactured by Goodrich)) and the like; Quaternary ammonium ethers [eg, hydroxyethylcellulose hydroxypropyllauryl dimethylammonium ether (Quarterly Soft LM-200 (manufactured by Union Carbide)) and the like; acrylic acid / methacrylic acid / alkyl acrylate / alkyl methacrylate / methacrylic acid Oxyethylene alkyl ether ester copolymer [Example For example, a polyoxyethylene (20) stearyl ether ester copolymer of acrylic acid, methacrylic acid, alkyl acrylate, alkyl methacrylate, methacrylic acid (Aculin 22 (manufactured by ISP)), and an alkyl acrylate copolymer emulsion ( Accurin 33 (manufactured by ISP)). One or more of these amphiphilic polymers can be selected and used. Among them, in particular, polyoxyethylene alkyl ether ester copolymer of acrylic acid, methacrylic acid, alkyl acrylate, alkyl methacrylate, methacrylic acid, and acrylic acid, methacrylic acid, alkyl acrylate, alkyl methacrylate, methacrylic acid Polyoxyethylene (20) stearyl ether ester copolymer is preferred from the viewpoints of emulsifying dispersibility, stability and film forming properties.

The amount of the component (A) is 0.1 to 10% by weight (hereinafter, simply referred to as%) in the hair cosmetic, particularly 0.1% by weight.
5 to 5% is preferable in that the hair has good viscosity and good usability.

(B) Powders include inorganic powders such as talc and metal soap; polyamide resin powder (nylon powder), polyethylene powder, polyalkyl acrylate powder, polymethyl methacrylate powder, and styrene and acrylic acid. Organic powders such as copolymers and polymethylsilsesquioxane powders; and other silicone rubber powders and carbon black. Of these, spherical powders, more particularly those having an average particle diameter of 5 μm or more, and more preferably 5 to 20 μm, are particularly preferred because the smoothness is particularly remarkable. One or more types of powder can be used, and the amount of the powder is 0.1 to
10%, especially 0.5 to 5%, is preferred for obtaining sufficient hair-styling properties and good feel.

(C) Oils which are pasty (semi-solid) at room temperature have a melting point at a temperature exceeding the range of room temperature (15 to 25 ° C.) and are not completely solidified in this range. Oils that are distinguished from ointment-like, petrolatum-like, etc. in official publications (such as cosmetic primordia), lanolin, trilanolin fatty acid glyceryl, soft lanolin fatty acid, petrolatum, branched or hydroxylated fatty acid cholesteryl, diamine Pentaerythritol fatty acid esters (such as dipentaerythritol hexaoxystearate). Of these, cholesteryl esters of branched or hydroxylated fatty acids (highly water-containing paste-like fats and oils), such as cholesteryl isostearate and cholesteryl hydroxystearate, give a remarkable moist feeling while having a dry feeling without an oily feeling. It is particularly preferred because it has a very good feel that it has. One or more paste-like (semi-solid) oil agents can be blended, and the blending amount is in the range of 0.1 to 10%, especially 0.3 to 5% in the hair cosmetic, because the hair styling properties are not impaired and the feel is good. preferable.

In the present invention, the component (A)
When dimethylpolysiloxane (D) is added in addition to (C), smoothness is imparted to the hair, and the feel is dramatically improved. (D) One or more dimethylpolysiloxanes having various viscosities (based on the first method of cosmetic primordia) can be selected and used in combination, but those having a viscosity of 1000 to 1,000,000 mPa · s have a long lasting feel. It is preferable because of its excellent smoothness. The compounding amount of the component (D) is preferably 0.05 to 8% in the hair cosmetics in that both the hair styling property and the feel are good.

[0011] In addition to the above components, various components commonly used in cosmetics can be added to the hair cosmetic composition of the present invention as long as the performance is not impaired. For example, surfactants for viscosity adjustment, foaming, emulsification / dispersion aids, etc .; modified silicone oils such as polyether silicone, methylphenyl silicone, etc. for improving feel such as smoothness; Oils such as paraffin, liquid isoparaffin, waxes and solid paraffin, preservatives, ultraviolet absorbers, humectants such as polyols, amino acids and salts thereof, solvents, and various extracts can be added.

The hair cosmetic composition of the present invention is used for styling purposes, and may be in any form such as a solubilizing system and an emulsifying system. The dosage form may be any of lotions, gels, creams, waxes, aerosol foams and the like. Not restricted.

EXAMPLES Examples 1 and 2 and Comparative Examples 1 to 5 Milk lotions for hair having the composition shown in Table 1 were prepared, 2 g of the lotion was applied to the wig by hand, the hair was adjusted with a brush, and dried with a drier to finish. Were evaluated. All evaluations were sensory evaluations by ten specialized panelists, and the evaluation was made in five steps from 1 to 5. If the average value of all members is 2 or less, the result is × (not good), 2 to 3 or less is Δ (cannot be called either), 3 to 4 or less is ○ (good), and the value exceeding 4 is ◎ (very good). The results are shown in Table 1.

(1) Hair styling property: good cohesion of hair when applied to wig, judgment by naked eye (2) No creaking: sensory evaluation of finished hair (3) No oiliness: no finishing hair Sensory evaluation (4) Smoothness: Sensory evaluation of finished hair (5) Persistence of feel: After leaving the finished wig air-dried for half a day, sensory evaluation again (whether there is no squeakiness and good feeling without oiliness)
