Description

Technical Field

[0001] The present invention relates to solid powder cosmetics.

Background Art

[0002] Solid powder cosmetics such as powder foundations, face powders, blushes, and eyeshadows are mainly composed of powder components and oily components in many cases. Since they are easy to use and excellent in portability, they are a dosage form widely favored by consumers. In addition, in order to enhance portability, they are often stored in compact containers, and it is required to achieve both impact resistance and good usability considering the carrying time. Furthermore, since solid powder cosmetics may be used by applying the cosmetics to applicators such as brushes and sponges and then applying them to the skin, the ease of taking up the cosmetics on the tool, the scattering property during use, and the adhesion to the skin are also emphasized.

[0003] So far, technologies for suppressing the impact resistance and powder scattering of solid powder cosmetics have been developed. For example, a solid powder cosmetic has been proposed in which the content of the oily component is 5 to 25% by mass based on the total amount of the solid powder cosmetic, and the oily component contains (A) a silicone compound having a viscosity of 4000 to 100000 mPa·s at 25°C and (B) an oily agent in a semi-solid state at 25°C (see Patent Document 1).

[0004] In addition, even in the case of a hair brush made of synthetic resin, technologies for powder cosmetics having good take-up property and transfer property of the powder cosmetic, excellent usability, and further excellent impact resistance in the case of a molded solid powder cosmetic have been developed. A powder cosmetic containing a fluorine compound-treated powder, silicone oil, and petrolatum has been proposed (see Patent Document 2).

Patent Document 1

Patent Document 2

[0006] However, the solid powder cosmetic described in Patent Document 1 contains a large amount of high-viscosity oil agents and semi-solid oil agents. Although the adhesiveness is high, the slipperiness is poor, and the cosmetic is likely to cake and it may be difficult to form a uniform cosmetic film. On the other hand, as a conventional technique, by containing spherical powder, although the slipperiness can be improved, the quality regarding powder scattering and impact resistance is not satisfactory, and there may be a limitation in the usability. Further, in the powder cosmetic described in Patent Document 2, although the pick-up to the brush, the adhesiveness to the skin, and the impact resistance have been improved, when a large amount of plate-like powder with a high aspect ratio is contained, there is a problem of powder scattering. Therefore, although an attempt was made to develop a solid powder cosmetic by combining the techniques of Patent Document 1 and Patent Document 2, it is difficult to achieve both contradictory effects of excellent impact resistance, no caking, and no powder scattering. Further, it has been difficult to develop a solid powder cosmetic having excellent adhesiveness to the skin and a moist feeling in use. Therefore, an object of the present invention is to develop a solid powder cosmetic that achieves both contradictory effects of excellent impact resistance, no caking, and no powder scattering, and further has excellent adhesiveness to the skin and a moist feeling in use. Means for Solving the Problems

[0007] In view of the above circumstances, the present inventor has intensively studied to develop a solid powder cosmetic containing a large amount of plate-like powder that does not scatter powder, has good pick-up, adheres firmly to the skin, and is less likely to cake while having a moist feeling in use. As a result, it has been found that by combining plate-like powder, a semi-solid oil agent, and ethyl cellulose, all of the above-described qualities are satisfied and the impact resistance of the solid powder cosmetic is improved, leading to the completion of the present invention.

[0008] That is, the present invention provides the following components (A) to (C); (A) Plate-like powder (B) An oily agent in semi-solid form at 25°C (C) Ethyl cellulose It provides a solid powder cosmetic containing the same.

[0030] The solid powder cosmetic of the present invention exerts the effects of the present invention by combining a powder component containing component (A) and an oily component containing components (B) and (C), and may contain components (D), (E), and other components as necessary. In particular, by containing a small amount of water and / or polyhydric alcohol, the binding force between powders can be enhanced, and the lack of powder scattering and the moist feeling during use can be improved. Therefore, the polyhydric alcohol may be any alcohol having two or more valences, and dihydric to tetrahydric alcohols are preferred. The content of such water and / or polyhydric alcohol is not particularly limited as long as it does not interfere with the effects of the present invention. However, in terms of the total amount of water and polyhydric alcohol, the lower limit is preferably 0.001% or more, more preferably 0.01% or more, and even more preferably 0.05% or more.

The upper limit is preferably 3% or less, more preferably 2% or less, and even more preferably 1% or less.

[0031] The solid powder cosmetic of the present invention can be produced according to a conventional method. For example, a powder section containing components (A), (D), and (E) is uniformly mixed, the oily section containing components (B) and (C) is heated and dissolved as necessary, the oily section is added to and mixed with the powder section, and a composition for solid powder cosmetic can be obtained by filling it into a container, but it is not limited to this production method.

[0032] In addition, the method of filling the container is not particularly limited, and dry filling or wet filling can be selected. Dry filling can be obtained, for example, by filling an appropriate amount of the solid powder cosmetic composition manufactured above into a container such as a metal tray and then compression molding. On the other hand, wet filling can be obtained, for example, by filling a container with a mixture of the solid powder cosmetic composition manufactured above and a solvent, and then removing the solvent. In the present invention, the solid powder cosmetic obtained by the wet molding method is preferable in terms of exhibiting the effects of the present invention. As the solvent, a volatile compound having a boiling point of 260°C or lower at normal pressure is preferable. Specifically, as the aqueous component, water, or a low-boiling alcohol such as ethyl alcohol or isopropyl alcohol, and as the oily component, a low-boiling hydrocarbon oil such as isododecane, isohexadecane, or light liquid isoparaffin, a low-polymerization-degree dimethylpolysiloxane, methyltrimethicone, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, or other low-boiling chain or cyclic silicone oils, a low-boiling fluorine compound such as a low-boiling perfluoropolyether, etc. can be mentioned, and these can be used as a mixture by combining one or more of them. In the present invention, among these solvents, it is preferable to use a low-boiling hydrocarbon oil such as isododecane, isohexadecane, or light liquid isoparaffin. The amount of the solvent to be added can be arbitrarily selected, but it is preferable to use 10 to 150 parts of the solvent with respect to 100 parts of the solid powder cosmetic composition. When the amount of the added solvent is small, it can be manufactured by compression molding in the same manner as the dry molding method and then removing the solvent by drying or the like. Also, by increasing the amount of the added solvent further, the cosmetic base before molding can be made into a slurry state to impart fluidity, and after filling into a container or an inner dish, the solvent can be removed by vacuum suction and / or drying or the like. Specifically, there are a method of providing a large number of holes in the press pad used for compression during filling and sucking and removing the solvent by vacuum, a method of sucking and removing the solvent using a highly absorbent cloth or non-woven fabric or the like during pressing, a method of drying and removing the solvent by heating in a constant temperature bath capable of controlling the temperature after molding, etc. Among the wet molding methods, a filling method in which the mixture before molding is made into a slurry state is preferable in terms of exhibiting the effects of the present application.
