Description

The present invention relates to a hair cosmetic, and more particularly to a hair cosmetic that has a setting power for hair, gives a soft and supple feel, and gives a moist finish.

In recent years, women's hair care behavior has changed greatly. For example, styling agents for making various hair styles and hair care products for preventing / care of hair damage have not been used properly. The trend of not having a hassle in busy daily life is also appearing in the actions for hair care, and in addition to the desire to do style ring and hair care at the same time, the economics of being able to double as a product There are also good reasons. In addition, as a recent hair trend, there is a current situation that natural and coherent hair styles are preferred and becoming mainstream.

As hair cosmetics that combine styling and hair care, in addition to all-in-one type shampoos and treatments for in-bath products, there are forms such as liquids, emulsions, creams, and gels as out-bath products. Above all, emulsion cosmetics are widely used for reasons such as being easy to take out and easy to spread during application.

In order to style and maintain the shape of hair, you can use set resin blended sprays, foam, mist, gel, etc., or use wax or stick products with high solid oil content, When treating hair, use milky or oily products with high care effects. However, it is difficult to impart a care effect while being set. Especially in milky products, the oil component is highly blended, so even if a resin or polymer with set properties is blended, the effect is oily. There were many issues that were lost. For cosmetics to overcome such problems, for example, an adhesive polymer compound is combined with an oil agent (see, for example, Patent Document 1), an anionic resin and a semipolar resin are combined with polyaspartic acid and The derivative may be combined with silicone, polyhydric alcohol, etc. (see, for example, Patent Document 2), or adhesive components such as diglycerin, sugar alcohol, a sticker, and a resin may be combined at a specific ratio (for example, patents). In addition to that, by combining the oil-based skeleton formulation with a polymer and a nonionic active agent at a specific ratio (for example, see Patent Document 4), an attempt is made to achieve both moist feeling and setability. Yes.

However, even if sticky ingredients are used, there is a feeling of setness to some extent, but the feeling of stickiness after use and after use is large, and when using a polymer or resin that has little stickiness, the hair is soft and stiff. Even if silicone or oil is added to care for and moisturize, there is a problem that only a small amount can be blended in order to maintain setability.

Therefore, there has been a strong demand for the development of a hair cosmetic that has setability for hair, gives a soft and supple feel, and gives a moist finish.

JP-A-11-116443 Japanese Patent Laying-Open No. 2005-330216 JP 2011-6358 A Japanese Patent No. 50147533

In view of the above circumstances, an object of the present invention is to provide a hair cosmetic that has a setting property for hair, gives a soft and supple feel, and gives a moist finish.

As a result of intensive studies to achieve the above-mentioned object, the present inventors have obtained 10 to 20% by mass of a liquid oil at room temperature, a nonionic polymer, a carboxyvinyl polymer, an amine oxide group-containing resin, The present inventors have found that the above problem of hair cosmetics can be solved by combining a colored rice extract and a rice bran fermented liquid.

That is, the hair cosmetic composition of the present invention is a hair cosmetic composition characterized by containing the following components (A) to (E).
(A) 10-20% by mass of liquid oil at room temperature
(B) Nonionic polymer (excluding carboxyvinyl polymer)
(C) Carboxyvinyl polymer (D) Amine oxide group-containing resin (E) Colored rice extract and rice bran fermentation broth

According to the hair cosmetic composition of the present invention, it has a setting property with respect to the hair, gives a soft and supple feeling, and gives a moist finish.

Hereinafter, the hair cosmetic composition of the present invention will be described in detail.

The oil component which is liquid at room temperature used for the component (A) of the present invention is not particularly limited as long as it can be used as a raw material for cosmetics. For example, hydrocarbons liquid at room temperature such as isoparaffin and light isoparaffin; Cyclic silicones such as cyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane; chain silicones such as octamethyltrisiloxane, tetradecamethylhexasiloxane, low viscosity methylpolysiloxane; ethyl isostearate, isopropyl isostearate, Cetyl 2-ethylhexanoate, cetostearyl 2-ethylhexanoate, glycerin 2-ethylhexanoate, macadamia nut oil fatty acid cholesteryl, diisostearyl malate, 2-ethylhexyl palmitate, Glyceryl 2-ethylhexanoate, glyceryl triisopalmitate, pentaerythritol tetra-2-ethylhexanoate, isocetyl octoate, isostearyl octoate, isopropyl palmitate, isocetyl isostearate, dipentaerythritol fatty acid ester, octyl isostearate Examples include fatty acid ester oils that are liquid at room temperature such as fatty acid ester oils such as dodecyl and isononanoyl isononate; animal and vegetable oils that are liquid at room temperature such as liquid lanolin, squalane, jojoba oil, olive oil, macadamia nut oil, and almond oil. These oil components which are liquid at room temperature can be used alone or in combination of two or more.

In the present invention, the content of the component (A) is not particularly limited as long as a desired effect is imparted, but is usually preferably 10 to 20% by mass in the composition from the viewpoint of functionality. This is because 10% by mass or more is preferable in order to sufficiently obtain a moist feeling, and 20% by mass or less is preferable in order not to reduce the setting function.

Nonionic polymer used for component (B) of the present invention (excluding carboxyvinyl polymer)
For example, polyvinyl alcohol, polyvinyl pyrrolidone, vinyl pyrrolidone-vinyl acetate copolymer, vinyl pyrrolidone-vinyl acetate-vinyl propionate copolymer, vinyl pyrrolidone-vinyl acetate-acrylaminoacrylate copolymer, vinyl acetate / N-- Examples include vinyl-5-methyl-2-oxazoline copolymer, hydroxyethylcellulose, hydroxypropylcellulose, hydroxypropylmethylcellulose, methylcellulose, carboxymethylcellulose, polyvinylformamide, and polyvinylacetamide. Commercially available products can be used as these nonionic polymers, for example, as polyvinylpyrrolidone (Lubicol K-12, 17, 30, 60, 80, 90 (all manufactured by BASF), PVP K-15, Lubiscol VA28, 37, 55, 64, 73 (all manufactured by BASF), PVP / VA-735, as vinylpyrrolidone-vinyl acetate copolymer, such as 30, 60, 90, 120 (all manufactured by ISP) 535, 335, 235, S-630 (all manufactured by ISP), PVA-6450 (manufactured by Osaka Organic Chemical Industry Co., Ltd.), etc. ) And the like as a vinyl acetate / N-vinyl-5-methyl-2-oxazoline copolymer. Among them, polyvinyl pyrrolidone and vinyl acetate / vinyl pyrrolidone copolymer can be preferably used.These nonionic polymers can be used alone or in combination of two or more. They can be used in combination.

In this invention, the compounding quantity of (B) component becomes like this. Preferably it is 0.01-5 mass%, More preferably, it is the range of 0.3-2%. When the amount of the nonionic polymer is less than 0.01% by mass, the setting property with respect to the hair is insufficient, and when it exceeds 5% by mass, the amount adsorbed on the hair becomes too large, which causes inconvenience in touch. This causes problems.

The carboxyvinyl polymer of the component (C) of the present invention has a property of increasing the viscosity by alkali neutralization, and it is preferable to adjust, neutralize and thicken the pH with an alkali. The alkali as the neutralizing agent is not particularly limited, and examples thereof include alkanolamines such as diisopropanolamine, triethanolamine and aminomethylpropanol, potassium hydroxide and sodium hydroxide. As the carboxyvinyl polymer, a commercially available product can be used, and examples thereof include “Sintalen” series (manufactured by 3V SIGMA), “Carbopol” series (manufactured by BF Goodrich) and the like. These carboxyvinyl polymers can be used singly or in appropriate combination of two or more.

In the present invention, the amount of component (C) is preferably 0.01 to 5% by mass, more preferably 0.3 to 2% in the composition. When the blending amount of the carboxyvinyl polymer is less than 0.01% by mass, the setting property with respect to the hair is insufficient, and when it exceeds 5% by mass, the amount adsorbed on the hair becomes too large, causing inconvenience in touch. This causes problems.

The amine oxide group-containing resin which is the component (D) of the present invention is a copolymer having a long chain fatty acid acrylic ester, ethyl methacrylate amine oxide, acrylic acid and / or methacrylic acid as components, and amine oxide as a structural unit. It contains a group.

These amine oxide group-containing resins can be used singly or in appropriate combination of two or more.

In the present invention, the amount of component (D) is preferably 0.1 to 10% by mass, more preferably 0.5 to 5% by mass in the composition. If it is less than 0.1%, the setability and its holding power are limited, and if it exceeds 10%, the filling container may be clogged.

The rice used for the extract of colored rice which is the component (E) of the present invention and the rice bran fermented liquid is the rice of the genus Gramineae (scientific name: Oryza sativa), but the preferred part for use in the extract of colored rice is Colored rice seeds such as brown rice or rice bran. Colored rice is a variety of rice that contains a pigment in part or all of the seed coat, paste layer or starch layer in brown rice, and examples of such rice include red rice, black rice, and green rice. The colored rice extract is obtained by, for example, extracting colored rice powder with an organic solvent such as hexane, n-pentane, chloroform, benzene, ethyl acetate, or a mixture thereof. The extraction temperature may be any of cold temperature, room temperature, and high temperature. When blended in the hair cosmetic composition of the present invention, the colored rice extract may be one obtained by concentrating and drying the extract or diluting it with ethanol or the like. The rice bran used in the rice bran fermented liquid is a mixture of pericarp, seed coat, embryo and paste layer pulverized product obtained when white rice is used as the brown rice of the plant rice (scientific name Oryza sativa). Although not specifically limited, ethanol is distilled off from an extract obtained by adding yeast to a rice saccharified saccharified solution obtained by adding α-amylase and β-amylase to rice bran and fermenting it. -Prepared with BG. These colored rice extracts and rice bran fermented liquor can be used by purchasing commercially available products such as RedRiceExtract (GSI Creos), black rice extract PC (manufactured by Oriza Yuka), rice bran fermented extract (Maruzen Pharmaceutical). For example).

In the present invention, one of these colored rice extracts and one of the rice bran fermented liquids may be used alone or in combination of two or more. The blending amount is desirably 0.0001 to 5% by mass with respect to the total amount of the hair cosmetic, but is preferably 0.001 to 1% by mass. If it is 0.001 mass% or more, the hair's supple feeling will be sufficiently obtained, and if it is 5 mass% or less, the feeling of firmness will not increase.

In the hair cosmetic composition of the present invention, other additional components used in ordinary hair cosmetic compositions can be further blended as necessary within the range not impairing the effects of the present invention. As these additional components, for example, one kind further selected from a moisturizer, a plant extract, a surfactant, a thickener, a set agent, an oil component, a pigment, a pH adjuster, a bactericide, a propellant, and a fragrance. Or 2 or more types can be contained. Such components are usually blended in an amount of preferably about 0.01 to 10% by mass, more preferably about 0.05 to 5% by mass, based on the total amount of the hair cosmetic.
