Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair styling cosmetic composition, and its purpose is to impart a unique dull or natural matte or dull state to the hair, and to impart a light effect. It is intended to provide a hair styling cosmetic composition capable of imparting hair styling properties.

[0002]

2. Description of the Prior Art Most of human hair is degenerated and remains in the center of the head nowadays, while the purpose of hair of other mammals is to protect the skin and maintain body temperature. It can be said that the role is merely cosmetic. Hair care is necessary for such beauty.
Therefore, in order to care for the hair, a cleaning agent for hair as a premise of beauty, a hair restorer, a cosmetic for hair, a hair dye and the like are commercially available. There are cosmetics for hair, especially for beauty purposes, for the purpose of styling hair, maintaining the hairstyle after styling, and imparting luster.

[0003] Hair cosmetics include an oil-based hair styling material containing a large amount of oily components such as vegetable oils and waxes without water, and water-in-oil type or oil-in-water containing various surfactants in water and oily components. Can be roughly classified into aqueous hair styling agents in the form of emulsions. Oil-based hair styling agents represented by hair oils, pomades, cosmetics, etc. have the advantage of having excellent hair styling properties, but on the other hand, they have a sticky feel, a heavy feel, a glaring unnatural luster on hair, and even shampoo It had the drawback of being hard to fall off. On the other hand, there is an aqueous hair styling agent typified by gels and water gels as a hair cosmetic with less sticky feeling. This water-based hair cosmetic composition has a less sticky feeling than the oil-based hair styling material and has a refreshing feeling of use, and further has the advantage that it is easy to remove with shampoo, but the hair styling property which is the main purpose of the hair styling material is It had the drawback of being weaker than oil-based hair styling products.

In the above-mentioned hair cosmetics, in addition to the role of styling and protecting the hair, emphasis has also been given to imparting luster to the hair. However, the luster imparted to hair by conventional hair cosmetics appears to artificially add luster to the hair in comparison with the luster of natural hair, resulting in an oily, glare-free gloss. It often gave a natural impression.

[0005]

In recent years, individualization of hairstyles has progressed from the viewpoint of beauty along with the diversification of lifestyles, and conventional hair cosmetics alone are
It is becoming difficult to meet the needs of the market. That is, although a cosmetic for hair as a hair styling material is required, the artificial oily and unnatural luster that accompanies hair styling tends to be shunned. Therefore, even if the hair is stylisted with a hair cosmetic composition, the styling of the hair after the styling is close to that of a natural hair or a matte state, that is, a matte hair can be stylisted. There has been a demand for a cosmetic for hair that has a visually natural finish.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The hair styling cosmetic composition according to the present invention comprises, as an essential component, a polyoxyethylene adduct of an oily component,
And polystyrene or a styrene copolymer.

The first essential ingredient of the hair styling cosmetic composition according to the present invention is a polyoxyethylene adduct of an oily ingredient.

The oily component which can be used in the present invention means a substance existing in an oily or solid state at room temperature, and specific examples thereof include oils and fats, waxes, higher fatty acids, higher alcohols and sterols. it can. Specifically, as fats and oils, avocado oil, olive oil, cocoa oil, camellia oil,
Examples include castor oil, coconut oil, sorghum, or hydrogenated castor oil, hydrogenated coconut oil, hydrogenated cocoa oil, and other hardened oils. Examples of the waxes include carnauba wax, candelilla wax, jojoba oil, montan wax, beeswax, lanolin, whale wax, and hydrogenated waxes such as hydrogenated lanolin, hydrogenated jojoba oil and hydrogenated carnauba wax. As higher fatty acids, lauric acid,
Myristic acid, palmitic acid, stearic acid, behenic acid, oleic acid, linoleic acid, ricinoleic acid, undecylenic acid, oxystearic acid, lanolinic acid, lanolin fatty acid, or synthetic fatty acids such as isopalmitic acid, isostearic acid, and isotridecanoic acid. It can be illustrated. Examples of higher alcohols include lauryl alcohol, myristyl alcohol, cetyl alcohol, cetostearyl alcohol, stearyl alcohol, oleyl alcohol, behenyl alcohol, lanolin alcohol, hydrogenated lanolin alcohol, hexyldecanol, octyldodecanol, and isostearyl alcohol. . Examples of sterols include cholesterol, dihydrocholesterol, phytosterol and the like.

In the hair styling cosmetic composition according to the present invention, the polyoxyethylene adducts of the above-mentioned oily components can be used, and in particular, polyoxyethylene adducts such as castor oil, hydrogenated castor oil, lanolin and reduced lanolin. It is preferable to use one or more of them. The reason why these are preferably used is that they have a high affinity for hair, are excellent in adhesiveness and wettability, and are excellent in foam water.

The number of moles of ethylene oxide added to the oil component is not particularly limited, but is preferably 3 to 70, and more preferably 5 to 50. The reason for this is that if the number of added moles is less than 3, the oily component has a strong stickiness because the hydrophilicity is weak. On the contrary, if the number of added moles is more than 70, the hydrophilicity becomes too strong and the feeling of finish is heavy. As a result, the feeling of use deteriorates, which is not preferable in any case.

Commercially available polyoxyethylene castor oil includes trade name NIKKOL CO-40TX (40EO) (manufactured by Nikko Chemicals) and tradename EMALEX C-40 (40E.
O. ) (Manufactured by Nippon Emulsion Co., Ltd.) and the like. As a polyoxyethylene hydrogenated castor oil, the trade name is NIKKOL H
Examples include CO-60 (60 EO) (manufactured by Nikko Chemicals Co., Ltd.) and trade name EMALEX HC-50 (50 EO) (manufactured by Nippon Emulsion Co., Ltd.). Examples of polyoxyethylene lanolin include trade name NIKKOL TW-30 (30EO) (manufactured by Nikko Chemicals Co., Ltd.) and trade name POLYCOL 15 (15E.
O. ) (Manufactured by Croda) and the like. As the polyoxyethylene reduced lanolin, the trade name is NIKKOL BW-30 (3
0E. O. ) (Manufactured by Nikko Chemicals) and the product name POLY
COL WH-150 (15EO) (manufactured by Croda) can be exemplified.

The blending amount of the polyoxyethylene adduct of the oily component used in the present invention is not particularly limited, but it is preferably 0.5 to 40.0% by weight, and 1.0 to 20% by weight in the entire hair cosmetic composition. More preferably, it is set to 0.0% by weight. The reason why this blending amount is preferable is that when the blending amount is less than 0.5% by weight, the hair styling power is weak and the hair cannot be stylisted, and the gloss of natural finish cannot be obtained.
This is because even if the amount exceeds 0% by weight, no significant improvement in hair styling power and luster can be seen and the finished feeling becomes heavy.

The second essential component of the hair styling cosmetic composition according to the present invention is polystyrene or a styrene copolymer. The number average molecular weight of the polystyrene or styrene copolymer used in the present invention is not particularly limited, but the number average molecular weight is preferably 1,000 to 1,000,000, and 2,000 to 500,000. Is more desirable. The reason why the above-mentioned number average molecular weight is more desirably used is that when the number average molecular weight is less than 1,000, the film has no film-forming ability and cannot be made to have a natural luster or matte. If it exceeds the range, the film is too hard, and when it is applied to the hair, a stiff feeling appears and the usability deteriorates.

The monomer copolymerizable with styrene of the styrene copolymer used in the present invention is not particularly limited. Specifically, as the monomer copolymerized with styrene, one or more of the following can be used. That is, acrylic acid, acrylic acid amide, acrylic acid ester, alkyl acrylate such as butyl acrylate, methacrylic acid, methacrylic acid ester, methacrylic acid amide, alkyl methacrylate such as butyl methacrylate, vinylpyrrolidone,
Examples include isoprene, silicone, vinyl acetate and the like. In particular,
Acrylic acid, acrylic acid amide, acrylic acid ester,
Methacrylic acid ester and the like are preferable. The reason why these are preferably used is that copolymerization with styrene is good and a stable copolymer is obtained.

The amount of polystyrene or styrene copolymer used in the present invention is not particularly limited, but for hair styling
It is preferably 0.5 to 30.0% by weight in the cosmetic , and more preferably 1.0 to 20.0% by weight. The reason for this is that with a blending amount of less than 0.5% by weight, the natural luster or delustering effect is not sufficiently exerted,
On the contrary, even if it is blended in excess of 30.0% by weight, natural luster or matte cannot be expected, and flaking occurs when used on hair, which is not preferable in any case. .

Examples of polystyrene used in the present invention include Nanospheres 100 Hydrophilic (produced by Exsymol) and Styrene MC White (produced by Ichimaru Falco).

Examples of the styrene copolymer used in the present invention include acrylic acid amide / styrene copolymer, trade name iodosol GH-52 (manufactured by NSC Japan), and trade name
Lytron 318) (manufactured by Morton International) and the like can be illustrated. Examples of acrylic acid / alkyl acrylate / styrene copolymers include trade name Iodosol GH-41 (manufactured by NSC Japan) and the like. styrene·
As the vinylpyrrolidone copolymer, trade name Antara 430
(Manufactured by ISP) and product name Polectron 430 (manufactured by ISP)
Etc. can be illustrated. Examples of the styrene / isoprene copolymer include Kraton D-116 (trade name, manufactured by Shell) and the like. Acrylic acid / styrene / ammonium methacrylate copolymer is trade name Syntran
5002 (manufactured by Inter polymer) can be exemplified.

If desired, water may be added to the hair styling cosmetic composition according to the present invention. Water to be mixed are generally purified water, the amount thereof may be blended with an appropriate amount in accordance with the amount of each cosmetic raw material, but in the hair styling cosmetic composition 1.0
˜90.0% by weight, preferably 50.0 to 90.0% by weight. The reason why the above blending amount is preferable is that if it is less than 1.0% by weight, a natural luster or matte state cannot be obtained, and the hair styling power is weak and hair styling cannot be performed. This is because if it is blended in an amount exceeding the range, the dryness is impaired and the sticky feeling is deteriorated.

The hair styling cosmetic composition according to the present invention may contain a lower alcohol for the purpose of improving the drying property. The lower alcohol used in the present invention is not particularly limited as long as it can be blended in cosmetics, and specific examples thereof include monohydric alcohols having 5 or less carbon atoms such as ethanol and isopropanol.

[0021] The amount of the lower alcohol is not particularly limited, it is preferable that a 1.0 to 99.0 wt% in total hair styling cosmetic, more preferably from 5.0 to 40.
It is good to set it to 0% by weight. The reason for this is that if the blending amount is less than 1.0% by weight, the effect of lower alcohol addition of improving the drying property cannot be obtained. Conversely, if the blending amount exceeds 99.0% by weight, the blending amount of other essential components is This is because it is not preferable in any case because the amount becomes too small and the desired effect cannot be obtained.

The hair styling cosmetic composition according to the present invention contains a water-soluble polymer, a polyhydric alcohol, an ultraviolet absorber, a fragrance, a preservative, and a coloring agent in addition to the components described above as long as the stability thereof is not impaired. An agent, a chelating agent, an antibacterial agent, a moisturizing agent, a cooling agent, vitamins, a plant extract, a pH adjusting agent, or a surfactant may be added according to the purpose.

The hair styling cosmetic composition according to the present invention can be applied to various dosage forms. Specifically, it is preferably used for dosage forms such as hair foam, hair gel, hair wax, hair cream and hair blow. You can

When the hair styling cosmetic composition according to the present invention is used as an aerosol agent such as a hair foam agent, it can be prepared by blending a propellant. The propellant is not particularly limited as long as it is blended in cosmetics, and specifically, low-boiling hydrocarbons having 4 or less carbon atoms such as propane and butane, low-boiling ethers such as dimethyl ether, and liquefied petroleum. Gas etc. can be illustrated.

The amount of the propellant compounded is not particularly limited,
When the content of the aerosol container is 100% by weight,
The amount is preferably 1.0 to 30.0% by weight, and more preferably 3.0 to 20.0% by weight. The reason for setting the above blending amount is that if the blending amount is less than 1.0% by weight, the undiluted solution in the aerosol container cannot be jetted to the end, and conversely, if the blending amount exceeds 30.0% by weight, the aerosol is mixed. This is because it is not as effective as injecting the stock solution in the container to the end, and there is a problem in that the stability of foam as a foam is impaired.
