Description

Oily solid cosmetics

The present invention relates to an oily solid cosmetic. More specifically, an oily solid cosmetic is excellent in pore blocking effect, dispersibility, and usability (softness and smoothness).

Foundation or makeup products may require a repairing effect that makes fine lines and pores inconspicuous. In such a pore-blocking cosmetic material, conventionally, a spherical powder is blended and pores are concealed by the diffusion effect of the powder (see, for example, Patent Documents 1 to 4). In particular, cerium oxide having a high refractive index or the like is widely used and can be multiplied by the matte effect at the time of completion of makeup, but the pore blocking effect is limited. Therefore, it is necessary to have a pore blocking effect that can overcome this spherical powder.

Further, the dispersion obtained by dispersing the component (b) of the present invention in an oil component is described in Patent Documents 5 to 7, but in these documents, other blending components used in the cosmetic of the present invention are used. There are no records or tips for the combination.

One or two or more kinds of the components (a) can be used.

The blending amount of the component (a) is 2 to 10% by mass, preferably 3 to 7% by mass, based on the total amount of the cosmetic of the present invention. In the case of less than 2% by mass, it is difficult to make the cosmetic into a solid state. On the other hand, in the case of more than 10% by mass, the cosmetic becomes too hard and it is difficult to take it out of the container by hand.

[(b) component]

The organically modified clay mineral as the component (b) may be an organic polar compound or an organic cation substituted with an exchange cation intercalated between crystal layers of a clay mineral (for example, montmorillonite, saponite, hectorite, bentonite, etc.). The material obtained, etc. In the present invention, a cationically modified clay mineral obtained by treating a water-swellable clay mineral with a 4-stage ammonium salt type cationic surfactant is suitably used.

A method for obtaining a cationically modified clay mineral by treating the above water-swellable clay mineral with a 4-stage ammonium salt type cationic surfactant, for example, The water-swellable clay mineral and the quaternary ammonium salt type cation surfactant are subjected to a dispersion stirring treatment in a low boiling point solvent such as water, acetone or a lower alcohol to remove a low boiling point solvent. In addition, water-swellable clay minerals may be blended with a grade 4 ammonium salt type cationic surfactant to impart organic denaturation in the formulation, and materials obtained in this manner may also be suitably used. Further, a 4-stage ammonium salt type cationic surfactant and a nonionic surfactant may be used in combination as needed.

The cationic modified clay mineral obtained by treating the water-swellable clay mineral with a 4-stage ammonium salt type cationic surfactant can be exemplified by dimethyl distearyl ammonium hectorite (= Quaternium-18 Hectorite) or dimethyl distear Ammonium bentonite (=Quaternium-18 Bentonite), or di-octadecyldimethylammonium montmorillonite, octadecyldimethylbenzylammonium montmorillonite, di-hexadecyldimethyl Ammonium montmorillonite, etc. These are, for example, "BENTON 38VCG" (=Quaternium-18 Hectorite), "BENTON 34" (=Quaternium-18 Bentonite) (any one of Elementis Specialities), "Claytone 40", "Claytone SO" One of them is sold in the market in the form of Southern Clay Co., Ltd., and can be obtained by commercial means. One or two or more kinds of the components (b) can be used.

The component (b) is preferably a dispersion in a form dispersed in an oil. The dispersion can be a material described in Patent Document 5 of the prior art document. Further, the production method can also be carried out by the production method described in Patent Document 5.

That is, the organically modified clay mineral system has an average thickness of 2 μm or more. The layered structure usually becomes an aggregate, and thus it is difficult to disperse in the oil in the state of the layered structure. Then, in the oil component, the organic denatured clay mineral is subjected to a release treatment by mechanical shearing force and/or a punching force, thereby performing flaking to have an average thickness of 0.1 μm or less and an average long diameter of about 0.5 to 50 μm. Organically modified clay mineral particles constructed of platy particles. Thereby, each of the plate-like particles of the organically modified clay mineral does not substantially aggregate in the oil component and can be dispersed.

Specifically, it can be obtained as a dispersion having fluidity at a low viscosity by a treatment method as described below. That is, glass beads (or zirconia beads) having a diameter of about 1 mm are added in the same volume by a mixture of commercially available organic denatured clay minerals (usually a layered aggregate having an average thickness of 2 μm or more) and oil. Etc.), and using a paint shaker (Paint Shaker), a bead mill, etc. to apply mechanical shear and/or punching force to exfoliate. Once the dispersion is obtained, it does not agglomerate again in the oil phase such as polyoxygenated oil, and a good dispersion state can be maintained.

The oil component in which the organic denaturing clay mineral is dispersed is not particularly limited, and is suitable for all oils which are liquid at normal temperature, and is particularly suitable for use as a polyoxygenated oil. As the polyoxygenated oil, a chain polyoxyalkylene such as dimethyl polyoxyalkylene or methylphenyl polyoxyalkylene, octamethylcyclotetraoxane or decamethylcyclopentaoxane can be used. In addition to the cyclic polyoxoxane such as dodecamethylcyclohexaoxane, various polyoxynitrides which form a three-dimensional network structure, polyfluorene oxide, or polyoxyxene may be used as long as there is no particular problem. (Amino-modified polyoxyalkylene oxide, alkyl-modified polyoxyalkylene oxide, fluorine-denatured polyoxyalkylene, etc.), and the like. Organic denatured clay in dispersion from the standpoint of dispersibility of organically modified clay minerals The amount of mineral dispersion (mixing amount) should be set to be about 0.25 to 30% by mass of the organically modified clay mineral in the oil content of the dispersion. By using the dispersion of the organically modified clay mineral in the oil, the actual blending amount of the organically modified clay mineral in the cosmetic can be increased as compared with the case of directly using the organic denatured clay mineral, thereby further effectively utilizing the pores In addition, in terms of usability, it is also possible to more effectively and effectively exert a soft and smooth feeling of use like fresh chocolate because of the excellent adhesion-increasing effect.

The blending amount (actual component) of the component (b) accounts for 2.5 to 8% by mass, preferably 3 to 7% by mass, based on the total amount of the cosmetic of the present invention. When it is less than 2.5% by mass, it is difficult to exhibit the effect (for example, flexibility, smoothness, and the like) of the blended component (b). On the other hand, when it exceeds 8% by mass, the cosmetic material becomes too hard. And it is difficult to fill the container.

[(c) component]

The copolymer represented by the above formula (I) can be produced, for example, by A solution of polyglycerol diallyl ether and a single-end hydrogenated dimethyl polyoxyalkylene is added with a solution of chloroplatinic acid isopropanol, which is heated and reacted, and an aqueous hydrochloric acid solution is added thereto, and the mixture is superheated and hydrolyzed. Sodium bicarbonate water, after neutralization, was obtained by purification and evaporation. However, it is not limited by this manufacturing method. The component (c) may, for example, be dibutyl dimethyl fluorenone polyglycerol-3 or the like.

The blending amount of the component (c) is from 0.3 to 8% by mass, preferably from 0.5 to 6% by mass, based on the total amount of the cosmetic of the present invention. When the content is less than 0.3% by mass, even if the cosmetic component is heated and melted, the fluidity is low, so that it is difficult to fill. On the other hand, when it exceeds 8% by mass, the cosmetic becomes It is prone to color streaks or stickiness.

[(d) component]

The cationic surfactant as the component (d) is not particularly limited as long as it can be used as a general cosmetic, and examples thereof include stearin trimethylammonium chloride and cetyltrimethylammonium chloride. An alkyltrimethylammonium salt such as tetradecyltrimethylammonium chloride or lauryltrimethylammonium chloride or a dialkyldimethylammonium salt such as distearyl dimethylammonium chloride , an alkyl pyridinium salt of a poly(N,N'-dimethyl-3,5-methylenepiperidinium) chloride, a cetylpyridinium chloride or the like, an alkyl quaternary ammonium salt, an alkyl group a dimethylbenzylammonium salt, an alkylisoquinolinium salt, a dialkylmorpholinium salt, a polyoxyethylene (hereinafter POE) alkylamine, an alkylamine salt, a polyamine fatty acid derivative, a pentanol fatty acid derivative, Benzokonium Chloride, Benzothornium Chloride, and the like.

When the content is less than 0.1% by mass, even if the cosmetic component is heated and melted, the fluidity is low, so that it is difficult to fill. On the other hand, when it is more than 2% by mass, the cosmetic is It becomes heavy when it is spread, and the usability tends to deteriorate.

[(e) component]

The component (e) is a branched saturated fatty acid having 14 to 24 carbon atoms (preferably 16 to 22). Specific examples thereof include isomyristate, isopentadecanoic acid, isopalmitic acid, isostearic acid, isoaragic acid, and isobehenic acid. It should be isostearic acid. The component (e) may be used alone or in combination of two or more.

In the present invention, when a linear saturated fatty acid or a branched unsaturated fatty acid is used instead of the component (e), the cosmetic is hardened in a state of high viscosity, and it becomes difficult to fill the container.

The blending amount of the component (e) is from 0.2 to 7% by mass, preferably from 0.5 to 5% by mass, based on the total amount of the cosmetic of the present invention. When the content is less than 0.2% by mass, even if the cosmetic component is heated and melted, the fluidity is low, so that it is difficult to fill. On the other hand, when it exceeds 7 mass%, the cosmetic becomes It is prone to color streaks or stickiness.

In the present invention, it is preferred to blend the blending ratio of (d) component: (e) component = 1:15 to 3:5 (mass ratio) from the viewpoint of preventing color bleeding.

The cosmetic of the present invention is a solid preparation in which the above components (a) to (e) are essential components. In the past, it has been difficult to blend the component (b) in a large amount, and if it is blended in a large amount, there is a disadvantage that the phenomenon such as oil slicks easily occurs in the cream base. In the present invention, by setting the dosage form to a solid state or combining the three components (c) to (e) as a dispersing agent, these disadvantages can be overcome, and at the same time, the component (b) can be produced. The pore concealment effect is further improved. Further, by the thickening effect of the component (b), a soft and smooth feeling of use can be exhibited. Further, in the case where the component (b) is used as the dispersion in the oil, the hardness of the preparation can be more effectively suppressed to be excessively high. Therefore, it is easy to take out the cosmetic from the container by hand during use, and it is also possible to exhibit It is easy to apply such an effect.

In the present invention, in addition to the above-mentioned essential components, a powder component which can be further blended (f) can be further added. By blending the component (f), the pore concealing effect can be further improved.
