Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a semi-solid hair cosmetic composition, and its purpose is to impart a soft and moderate lumpy feeling to the hair while maintaining the flexibility, and to provide a moist and moisturizing feeling. It is an object of the present invention to provide a semi-solid hair cosmetic which gives natural luster, has no sticky feeling, and has excellent finger-passing properties and hair restyling properties. In the present invention, the semi-solid form means a wax-like, cream-like, or gel-like substance having a viscosity of 10 Pa · S or more.

[0002]

[Prior Art] While preparing a disturbed hairstyle,
Hair styling products are used to maintain a styled hairstyle for a long time. Examples of hair styling products that have been used for a long time include oily hair styling products such as hair oil and pomade. Since these oil-based hair styling agents contain a large amount of oil-based components, they are excellent in the hair styling ability to hold down the hair, that is, the hair is hardened and styled. However, there is a drawback in that it is not possible to impart a soft and moderate cohesive feeling, and an oily sticky feeling is imparted. In addition, there is a gel-like hair styling material in which a water-soluble raw material is thickened by blending a thickening agent. This hair styling agent can suppress giving an oily greasy feeling like an oil-based hair styling agent, but has a hard finish after hair styling,
It has a drawback that the hair feels squeaky.

Further, a water-soluble hair cosmetic composition is known as a hairdressing composition in which the above-mentioned drawbacks of the hairdressing composition such as stickiness and squeaky feeling are eliminated. A water-soluble hair cosmetic composition is a hair styling product in which an oily component is suspended in water using various surfactants. However, although water-soluble hair cosmetics do not cause a sticky feeling or a squeaky sensation, the hairstyle holding power decreases as water evaporates, so that the hairstyle cannot be held for a long time. . This problem can be solved to some extent by blending a high molecular compound, but on the other hand, a stiff feeling tends to occur, and if the hairstyle that has been once messed up is disturbed, it is easy to restore the hair to the original condition. There was a new problem that I could not do it.

[0004]

On the other hand, there have been created hair creams and hair waxes which are oil-in-water type emulsion type cosmetics in which a relatively high content of oil is emulsified. Such a hair styling product does not give a feeling of stiffness, and moreover, even if the hairstyle once prepared is disturbed, the hair styling can be easily performed again as before. However, the oil-in-water emulsified cosmetic composition has a drawback of giving a sticky feeling, although it can give a soft and moderate cohesive feeling without giving a stiff feeling.

In view of such circumstances, as a result of intensive studies by the present inventors, as essential components, a high degree of polymerization methyl polysiloxane, acrylic acid polymer or acrylic acid / methacrylic acid alkyl ester copolymer, nonionic interface By blending an activator, higher alcohols and lower alcohols, it is possible to give the hair a soft and moderate cohesiveness while maintaining the flexibility, while giving a moist and moisturizing feeling and a natural luster, and yet it is sticky. The inventors have found that a semi-solid hair cosmetic having no feeling, excellent in finger-passing property, and excellent in hair styling can be obtained, and completed the present invention.

[0006]

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The semi-solid hair cosmetic composition according to the present invention will be described in detail below. The semi-solid hair cosmetic composition according to the present invention has, as essential components, a highly polymerized methyl polysiloxane, an acrylic acid polymer or an acrylic acid / methacrylic acid alkyl ester copolymer, a nonionic surfactant, a higher alcohol, and Lower alcohol is blended.

The first essential component of the semi-solid hair cosmetic composition according to the present invention is a highly polymerized methyl polysiloxane. The high polymerization degree methyl polysiloxane is a linear polymer having a siloxane bond as a skeleton. The average degree of polymerization of the high degree of polymerization methyl polysiloxane is not particularly limited, but 6
It is 50 or more, preferably 650 to 10,000.

The compounding amount of the high degree of polymerization methyl polysiloxane is not particularly limited, but is 0.01 to 2.0% by weight in the cosmetic.
And preferably 0.1 to 1.0% by weight. The reason for this is that if the amount is less than 0.01% by weight, a proper cohesive feeling cannot be obtained, and if the amount exceeds 2.0% by weight, a sticky feeling is given to the hair. In any case, it is not preferable.

The second essential component of the semi-solid hair cosmetic composition according to the present invention is an acrylic acid polymer and / or an acrylic acid / methacrylic acid alkyl ester copolymer. Both the acrylic acid polymer and / or the acrylic acid / methacrylic acid alkyl ester copolymer are blended as a thickener. The acrylic acid polymer is a water-soluble polymer having a carboxyl group. The gel formed from the acrylic acid polymer has a low stickiness and, even in a small amount, a high viscosity can be obtained. Further, it is highly safe and has many advantages such as being applicable to various solvents such as water, alcohols and polyhydric alcohols, and it suitably functions as a thickener.

The acrylic acid polymer used in the present invention is not particularly limited, and examples thereof include carboxyvinyl polymer and sodium polyacrylate, but it is preferable to use carboxyvinyl polymer. The reason for this is that it is easy to adjust the semisolid viscosity.
Examples of commercially available carboxyvinyl polymers include “Carbopol (manufactured by BFGoodrich Chemical Co.)” and “Hibiswako (manufactured by Wako Pure Chemical Industries)”.

The acrylic acid / methacrylic acid alkyl ester copolymer is a copolymer having both a hydrophilic portion derived from a carboxyl group and a lipophilic portion derived from an alkyl group. A gel formed only from an acrylic acid / methacrylic acid alkyl ester copolymer cannot maintain a high viscosity, but has a function of improving adhesion to hair and salt resistance. The acrylic acid / methacrylic acid alkyl ester copolymer used in the present invention is not particularly limited, but the alkyl group of the methacrylic acid unit preferably has 10 to 30 carbon atoms. The reason for this is that it is excellent in uniformly dispersing the high degree of polymerization methyl polysiloxane. As a commercially available acrylic acid / methacrylic acid alkyl ester copolymer,
The product name “PEMREN TR-1” and the product name “PEMUREN TR-2” (both manufactured by BFGoodrich) can be exemplified.

In the present invention, the acrylic acid polymer or the acrylic acid / methacrylic acid alkyl ester copolymer may be blended individually, or may be blended, but particularly in the present invention, they may be blended. It is preferable to mix them. The reason for this is that the high-polymerization degree methyl polysiloxane can be uniformly dispersed to facilitate the viscosity adjustment. The compounding ratio of the acrylic acid polymer and the acrylic acid / methacrylic acid alkyl ester copolymer is not particularly limited, but is 1: 0.1-3, preferably 1: 0.3-2. The reason for this is that when the amount of the acrylic acid polymer compounded is less than 0.1 of the amount of the acrylic acid / methacrylic acid alkyl ester copolymer compounded, the effect of compounding cannot be obtained, and 3
This is because when the weight exceeds 10 times, the feeling such as sticky feeling is deteriorated, which is not preferable in any case.

The blending amount of the acrylic acid polymer and / or the acrylic acid / methacrylic acid alkyl ester copolymer is not particularly limited, but is 0.01 to 5.0% by weight in the cosmetic.
And preferably 0.1 to 2.0% by weight. The reason for this is that when the compounding amount is less than 0.01% by weight, the thickening property is weak, and when the compounding amount exceeds 5.0% by weight, the viscosity becomes too high and the spreadability at the time of application becomes poor. This is because, in any case, it is not preferable because it adversely affects usability such as flaking.

In the present invention, a basic substance is added to neutralize the acrylic acid polymer and / or the acrylic acid / methacrylic acid alkyl ester copolymer to form a gel. Examples of the basic substance used include alkanolamines such as triethanolamine and monoethanolamine, ammonia, potassium hydroxide and sodium hydroxide. The amount of the basic substance blended is an amount sufficient to neutralize the acrylic acid polymer or the acrylic acid / methacrylic acid alkyl ester copolymer, and may be appropriately selected depending on the type and the amount of use of these components.

The third essential ingredient of the semi-solid hair cosmetic composition according to the present invention is a nonionic surfactant. The nonionic surfactant used is not particularly limited, and examples thereof include propylene glycol fatty acid ester, glycerin fatty acid ester, polyoxyethylene glycerin fatty acid ester, polyglycerin fatty acid ester, sorbitan fatty acid ester, polyoxyethylene sorbitan fatty acid ester, and polyoxyethylene. Sorbit fatty acid ester, polyoxyethylene alkylphenyl formaldehyde condensate,
Polyoxyethylene castor oil, polyoxyethylene hydrogenated castor oil, polyoxyethylene sterol and its derivatives, polyethylene glycol fatty acid ester, polyoxyethylene alkyl ether, polyoxypropylene alkyl ether, polyoxyethylene polyoxypropylene alkyl ether, polyoxyethylene Alkyl phenyl ethers, polyoxyethylene lanolin and its derivatives, polyoxyethylene beeswax derivatives, polyoxyethylene alkylamines, polyoxyethylene fatty acid amides, alkanolamides, sugar esters, polyoxyethylene hydrogenated castor oil pyroglutamic acid esters, polyoxyethylene Examples thereof include glyceryl pyroglutamic acid ester. In particular, in the present invention, it is preferable to use sorbitan fatty acid ester, polyoxyethylene sorbitan fatty acid ester, or the like, because the sticky feeling can be reduced and a good cohesive feeling can be provided.

In the present invention, one of the above-mentioned nonionic surfactants may be blended alone, or two or more nonionic surfactants may be mixed and blended. The blending amount of the nonionic surfactant is not particularly limited, but it is preferably 0.1 to 10.0 wt% in the cosmetic, and more preferably 0.5 to 5.0 wt%. The reason for this is that if the blending amount is less than 0.1% by weight, the effect due to the blending cannot be obtained, and if the blending amount exceeds 10.0% by weight, a sticky feeling is caused and the texture is adversely affected. In any case, it is not preferable.

The fourth essential ingredient of the semi-solid hair cosmetic composition according to the present invention is a higher alcohol. The higher alcohol in the present invention is a linear or branched monohydric alcohol having 10 to 23 carbon atoms, and may be unsaturated higher alcohol or saturated higher alcohol. Specifically, lauryl alcohol, myristyl alcohol,
Cetyl alcohol, cetostearyl alcohol, lanolin alcohol, hydrogenated lanolin alcohol, hexyldecanol, stearyl alcohol, isostearyl alcohol, behenyl alcohol, oleyl alcohol,
2-octyl dodecanol etc. can be illustrated. Of these, it is possible to give a feeling of cohesion and reduce the feeling of stickiness,
Preference is given to using behenyl alcohol.

In the present invention, one of the above-mentioned higher alcohols may be used alone, or two or more thereof may be mixed and used. The blending amount of the higher alcohol is not particularly limited, but 0.01 to 10.
It is preferably 0% by weight, and 0.1 to 5.0% by weight
Is more preferable. The reason for this is that when the amount is less than 0.01% by weight, the effect due to the compounding cannot be obtained, and when the amount is more than 10.0% by weight, the cosmetic material becomes brittle and the elongation during use becomes poor. In any case, it is not preferable.

The fifth essential ingredient of the semi-solid hair cosmetic composition according to the present invention is lower alcohol. The lower alcohol in the present invention is a linear or branched monohydric alcohol having less than 10 carbon atoms, and may be unsaturated lower alcohol or saturated lower alcohol. The lower alcohol used in the present invention is not particularly limited as long as it can be blended in cosmetics. Specifically, it is preferable to use a monohydric alcohol having 5 or less carbon atoms such as ethanol and isopropanol.

In the present invention, one of the above lower alcohols may be used alone, or two or more of them may be mixed and used. The amount of the lower alcohol is not particularly limited, but it is 1.0 to 30.0 in the cosmetic.
It is preferable to set it as the weight%, and it is 5.0 to 20.0 weight%.
Is more preferable. The reason for this is 1.0% by weight
If the blending amount is less than the above, the elongation at the time of use cannot be improved, and if the blending amount exceeds 30.0% by weight, the squeaky feeling may be adversely affected, or the stability of the cosmetic composition may be deteriorated. This is because in any case, it is not preferable because it is damaged.

The above are the essential components of the semi-solid hair cosmetic composition according to the present invention. However, in the present invention, each of the components described below can be appropriately mixed. Silicone oil can be added to the semi-solid hair cosmetic composition according to the present invention in order to improve the finger-passing property and gloss. As the silicone oil, low polymerization degree methyl polysiloxane having an average degree of polymerization of less than 650, methyl phenyl polysiloxane, methyl hydrogen polysiloxane, methyl cyclopolysiloxane, octamethyl cyclotetrasiloxane, decamethyl cyclopentasiloxane, dodecamethyl cyclohexene. Examples thereof include sasiloxane, octamethyltrisiloxane, and tetradecamethylhexasiloxane.
In particular, in the present invention, it is preferable to use a low-polymerization degree methyl polysiloxane because it is excellent in finger-passing property and hard to give a sticky feeling, and the kinematic viscosity at 25 ° C. is from 0.1 to 10.
It is more preferable to use 0 St.

When the silicone oil is blended, one of the above silicone oils may be used alone, or two or more of them may be mixed and used. When blending silicone oil, the blending amount is not particularly limited,
It is preferably 1.0 to 20.0 wt% in the cosmetic, and more preferably 5.0 to 15.0 wt%. The reason for this is that when the amount is less than 1.0% by weight, the finger-passing property is not improved, and when the amount is more than 20.0% by weight, a sticky feeling remarkably occurs. Is also not preferable.

Further, the semi-solid hair cosmetic composition according to the present invention may further contain a polyhydric alcohol in order to improve the cohesiveness and moisturizing feeling. Examples of the polyhydric alcohol that can be used in the present invention include ethylene glycol, propylene glycol, 1,3-butylene glycol, glycerin, diglycerin, triglycerin, polyglycerin, xylose, lyxose, arabinose, ribose, ribulose, glucose. , Galactose, fructose, mannose, sucrose, lactose, trehalose, sorbitol, maltitol, maltriose, mannitol, erythritol, xylitolose and the like. Of these, glycerin, 1,3-butylene glycol and the like are preferably used because they do not easily give a sticky feeling.

When the polyhydric alcohol is blended, one of the above polyhydric alcohols may be used alone, or two or more of them may be mixed and used. When the polyhydric alcohol is blended, the blending amount is not particularly limited, but is preferably 10.0 to 50.0 wt% in the cosmetic, and more preferably 15.0 to 30.0 wt%. . The reason for this is that if the blending amount is less than 10.0 wt%, a sufficient cohesiveness or moisturizing feeling cannot be obtained, and if the blending amount exceeds 50.0 wt%, a sticky feeling occurs. In any case, it is not preferable.

In the semi-solid hair cosmetic composition of the present invention, other than the above-mentioned components, as long as the stability is not impaired,
UV absorbers, fragrances, preservatives, chelating agents, antibacterial agents, moisturizers, cooling agents, vitamins, plant extracts, propellants, pH
You may mix | blend a regulator, other surfactants, etc. according to the objective.
