[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-138021 Summary of the Invention [Problem to be solved by the invention]

[0004] Makeup cosmetics contain titanium oxide, a color pigment, which has the effect of concealing dullness and uneven skin tone, but it has the problem of producing a pale color. To achieve this, the role of makeup, which is to produce vibrant colors that are aesthetically pleasing, create a healthy appearance, and give a natural impression, has traditionally been achieved by mixing highly saturated color pigments, such as red iron oxide (iron oxide red) and yellow iron oxide, and adjusting the brightness with black iron oxide to control the color. However, the use of highly saturated red iron oxide has the problem of easily causing color separation, making the skin dull and causing uneven skin tone. [Means for solving the problem]

[0005] Therefore, with the aim of developing a product that allows makeup cosmetics to match one's skin tone for a long time, the present inventors conducted extensive research to develop makeup cosmetics that blend seamlessly with the skin tone, do not leave a dull complexion, and do not cause uneven skin tone. As a result, they found that by using the white pigments titanium oxide and zinc oxide in combination with a specific inorganic red pigment with low saturation and silicic anhydride in combination, it is possible to obtain makeup cosmetics that blend seamlessly with the skin tone, do not leave a dull complexion, cause improved uneven skin tone, and do not change color over time when applied, compared to the conventional use of a mixture with iron oxide.

[0006] That is, one aspect of the present invention is a composition comprising the following components (A), (B), (C) and (D): (A) Titanium oxide (B) Zinc oxide (C) An inorganic red pigment having a hue angle of 0 to 72°, a value V of 2 to 7, and a chroma C of 5 to 7.5 as specified in the Munsell color system when measured in specular reflection (incident angle 0°, integrating sphere light reception). (D) Silica anhydride The present invention provides a makeup cosmetic containing the above. [Effects of the Invention]

[0007] The makeup cosmetic of the present invention has the effect that the makeup cosmetic blends seamlessly with the skin color, does not cause dullness, improves uneven skin tone, and provides a good finish, and the applied color does not change even after a long period of time.

The organic resin powder referred to here refers to a highly biodegradable organic resin powder other than cellulose powder. Examples of such organic resin powders include crosslinked or non-crosslinked organic resin powders such as polyamide resin, nylon resin, polyester resin, polyethylene resin, polytetrafluoroethylene resin, polypropylene resin, polystyrene resin, benzoguanamine resin, polymethylbenzoguanamine resin, polyurethane resin, vinyl resin, fluororesin, acrylic resin, melamine resin, butyl acrylate-vinyl acetate copolymer, styrene-acrylic acid copolymer, silicone resin, and divinylbenzene-styrene copolymer.

[0043] The makeup cosmetic of the present invention can be in the form of a liquid, emulsion, paste, cream, gel, powder, solid, or the like. Furthermore, the makeup cosmetic of the present invention may be in the form of a powder cosmetic, an emulsion cosmetic, or the like, with solid powder cosmetics being preferred as powder cosmetics, and water-in-oil emulsion cosmetics and oil-in-water emulsion cosmetics being preferred as emulsion cosmetics, with water-in-oil emulsion cosmetics being more preferred. The makeup cosmetic of the present invention can be used as a powder foundation, face powder, face powder, liquid foundation, concealer, blusher, eye shadow, sunscreen with makeup effect, and the like.

[0044] The makeup cosmetic of the present invention has the effect of improving the skin compatibility of makeup, eliminating dullness, improving color unevenness, resulting in a good finish, and maintaining the applied color even over a long period of time. Here, "good skin compatibility" means that the makeup cosmetic blends seamlessly with one's own skin color. "Dullness" refers to the pale, dark impression that results from the inclusion of titanium oxide, which is necessary for improving coverage. "Color unevenness" refers to the occurrence of scaly unevenness in the applied color of the makeup cosmetic when applied to the skin with a sponge or the like. Here, it is believed that the cause is non-uniformity of the color pigments in the makeup cosmetic, particularly the red pigment.

[0045] The makeup cosmetic of the present invention can be produced according to a conventional method. For example, a powder or emulsion-type makeup cosmetic can be produced by mixing and grinding all of the powder components including components (A) to (D), and then adding and mixing all of the oil components including component (F) as needed, and other components. [Example]

[0046] The present invention will now be described in more detail with reference to examples, but the present invention is not limited to these examples.

[0047] Examples 1 to 6 and Comparative Examples 1 to 2 Makeup cosmetics were prepared with the compositions shown in Tables 2 and 3, and were evaluated for (1) compatibility with the skin immediately after application, (2) lack of dullness immediately after application, (3) uniform finish, and (4) lack of change in applied color 6 hours after application. The results are also shown in Tables 2 and 3.

[0048] (Manufacturing method) (Table 2~Table 4) After mixing and grinding all the powder ingredients including components (A), (B), (C), and (D), an oil was added and mixed, and the resulting mixture was further ground in a grinder. The ground product was filled into a container and molded at a molding pressure of 500 to 2000 kgf to obtain a solid powder cosmetic (foundation). (Table 5) A powder phase containing components (A), (B), (C), and (D) was added to the oil phase and dispersed, and then the aqueous phase components were added and stirred with a homomixer to obtain a water-in-oil emulsion cosmetic (liquid foundation).

[0049] (Appearance color of various coloring pigments) The appearance color of each color pigment is shown in Table 1. The appearance color was measured by weighing 9 g of color pigment into a resin dish, stamping twice at 0.5 MPa, and measuring the color with a spectrophotometer (Color i5, X-Rite). The finished thickness was 3 mm.
