Description

[Technical Field]

[0001] The present invention relates to an oily cosmetic preparation. [Background technology]

[0002] Lip cosmetics such as lipstick and lip gloss, and oil-based makeup cosmetics such as eye shadow and blush are required to have strong color development and long-lasting wear. Oil-based cosmetics are also required to be non-sticky due to the oily base. Furthermore, with the diversification of preferences in recent years, there has been an increasing need for aesthetics, such as differences between the appearance color of cosmetics and the applied color. Oil-soluble dyes are used to improve color development and durability. Oil-soluble dyes are resistant to sweat, sebum, and friction, and are difficult to remove. However, oil-soluble dyes tend to discolor due to inorganic powders, moisture, etc., and may result in insufficient color development or reduced color durability during use. For example, Patent Document 1 describes that an oil-based cosmetic containing an oil-soluble dye, an organic acid, and a white cosmetic powder provides a stable appearance color and does not impair the color intensity upon application. Patent Document 2 describes an oil-based makeup cosmetic containing an oil-soluble dye and a specific oil agent, which develops color upon application to the body surface. Patent Document 3 describes that a cosmetic containing polyglycerol having an average degree of polymerization of 2 to 20, a polyglycerol branched fatty acid ester esterified with a branched fatty acid having 8 to 22 carbon atoms, and a coloring material has uniform dispersion of the coloring material, good color development, a vivid color finish, and excellent spreadability and adhesion to the skin.

[0004] However, all conventional cosmetics containing oil-soluble dyes suffer from discoloration during production due to the oil-soluble dye, and the vividness of the color upon application is not fully satisfactory. Furthermore, they are unable to reduce the stickiness of oil-based cosmetics. Furthermore, there is also the problem of difficulty in degassing during production. [Means for solving the problem]

[0005] The present inventors have discovered that by using a combination of an oil-soluble dye with specific nonporous spherical silica, a colorant, a non-volatile liquid oil, and a solid wax, it is possible to obtain an oil-based cosmetic that does not discolor during production, has excellent defoaming properties, has a different appearance color from the applied color, is a vivid color upon application, and has reduced stickiness.

[0006] The present invention relates to a composition comprising the following components (A), (B), (C), (D) and (E): (A) non-porous spherical silica having an average particle size of 2 to 20 μm and an oil absorption of 30 mL / 100 g or less; (B) oil-soluble dye, (C) a colorant other than component (B); (D) non-volatile liquid oil; (E) solid wax, Contains The present invention relates to an oil-based cosmetic preparation having a content of component (A) of 12% by mass or more.
