Description

  The present invention relates to a cosmetic, and more particularly, to a cosmetic suitable for a makeup cosmetic.

  Make-up cosmetics are cosmetics that hide skin troubles and make skin colors look beautiful using optical effects such as powder hiding power, coloring power, and light diffusion. Because of such optical effects, makeup cosmetics tend to deviate from their natural appearance in the finish, and development of means for correcting this has been desired. Against the backdrop of such needs, the covering power does not depend on titanium dioxide or zinc oxide, but depends on titanium mica or titanium sericite, and uses natural interference light to provide natural gloss. In addition, a method has been developed to relieve the hiding feeling of titanium dioxide or the like by using the diffusion / diffuse reflection effect of a powder having diffusion permeability such as silica. (For example, see Patent Document 1, Patent Document 2, and Patent Document 3) However, in these methods, unnaturalness has been improved, but on the other hand, it is preferable such as freshness and vivid shine. It did not lead to the creation of a facial expression.

  As a technique for controlling the optical effect of powder, a technique for uniforming the particle size distribution of spherical powder to make it monodisperse is known, and its effects include uniform color rendering with pigments and prevention of makeup collapse. Are known. (For example, see Patent Document 4, Patent Document 5, Patent Document 6, and Patent Document 7) However, there has been no known relationship with the creation of a favorable facial expression, such as freshness and vividness, It has not been known at all to use a monodispersed spherical powder having an average particle diameter of 2 to 4 μm as a cosmetic raw material. Accordingly, 1) 60-85% by weight of a plate-like powder and 2) 10-30% by weight of a spherical powder, wherein 90% by weight or more of the spherical powder has a mean particle size of 2-4 μm. A cosmetic that is a dispersed spherical powder has not been known at all.

  The present invention has been made under such circumstances, and it is an object of the present invention to provide a cosmetic that can create a favorable facial expression such as freshness and vividness in makeup cosmetics. To do.

In light of this situation, as a result of earnest research efforts for makeup cosmetics that can create a favorable facial expression, such as freshness and vibrancy, 1) Board 60-85% by mass of powder and 2) 10-30% by mass of spherical powder, wherein 90% by mass or more of the spherical powder is a monodispersed spherical powder having an average particle diameter of 2-4 μm. It has been found that a certain makeup cosmetic has such characteristics and has led to the completion of the invention. That is, the present invention is as follows.
(1) 1) 60-85% by mass of plate-like powder and 2) 10-30% by mass of spherical powder, wherein 90% by mass or more of the spherical powder has an average particle size of 2-4 μm A makeup cosmetic characterized by being a monodispersed spherical powder.
(2) The makeup cosmetic according to (1), further comprising 1 to 5% by mass of resin-coated titanium mica as a plate-like powder.
(3) Further, the plate-like powder includes a plate-like powder coated with a polymer or copolymer having methacryloyloxyethyl phosphorylcholine as a constituent monomer, (1) or (2) Makeup cosmetics as described in).
(4) The makeup cosmetic according to any one of (1) to (3), which is a finished white powder.
(5) The makeup cosmetic according to any one of (1) to (4), wherein natural makeup is realized.

  ADVANTAGE OF THE INVENTION According to this invention, in makeup cosmetics, the cosmetics which can create preferable expression feelings, such as freshness and vivid shine, can be provided.

(1) Plate-like powder which is an essential component of the cosmetic of the present invention The cosmetic of the present invention contains 60 to 85% by mass, more preferably 62 to 80% by mass of a plate-like powder as an essential component. It is characterized by that. The plate-like powder referred to in the present invention is the smallest line segment value with respect to the square root of the surface area of the largest surface. It means a generic name, and specifically, powders such as talc, mica, sericite, titanium mica, and titanium sericite can be suitably exemplified. Such a powder can be contained as it is, or after being subjected to a surface treatment with hydrogen methylpolysiloxane, a silylating agent, or the like. It is appropriate that the surface treatment is performed with a treatment agent of 0.5 to 10% by mass with respect to the mass of the powder. In the cosmetic of the present invention, such a plate-like powder can contain only one species, or can contain two or more species in combination. In the cosmetic of the present invention, such a plate-like powder embodies a natural covering power without showing thickness. The preferred form of the powder is to contain 1 to 5% by mass, more preferably 2 to 4% by mass of resin-coated titanium mica with respect to the total amount of the cosmetic. A commercially available product can be used as the resin-coated titanium mica, and a preferable commercially available product is preferably TPM powder 2003 manufactured by Daito Kasei Kogyo Co., Ltd. Furthermore, it is also preferable that the plate-like powder contains a plate-like powder coated with a polymer or copolymer containing methacryloyloxyethyl phosphorylcholine as a constituent monomer. By containing such a powder, the protective effect on the skin can be enhanced. Examples of such copolymers and polymers include polymethacryloyloxyethyl phosphorylcholine, methacryloyloxyethyl phosphorylcholine / butyl methacrylate copolymer, methacryloyloxyethyl phosphorylcholine / stearyl methacrylate copolymer, and the like. As the plate-like powder to be coated thereon, talc can be particularly preferably exemplified. Such a treated powder can be used after coating the above-mentioned polymer on these plate-like powders, or a treated powder already on the market can be purchased and used. Preferred examples of the commercially available powder include lipid talc (manufactured by Nippon Oil & Fats Co., Ltd.) in which talc is coated with a methacryloyloxyethyl phosphorylcholine / stearyl methacrylate copolymer. The preferable content of such components is preferably 5 to 20% by mass, particularly preferably 8 to 15% by mass in total.

(2) Spherical powder that is an essential component of the cosmetic of the present invention The cosmetic of the present invention contains 10 to 30% by mass, more preferably 12 to 25% by mass of a spherical powder as an essential component. To do. It is characterized in that 90% by mass or more, more preferably 95% by mass or more of the spherical powder is monodispersed with an average particle diameter of 2 to 4 μm, more preferably 2.5 to 3.5 μm. The type of the spherical powder is not particularly limited as long as it is spherical, but for example, anhydrous silicic acid, nylon, acrylic resin, methylpolysiloxane network polymer and the like can be preferably exemplified, and anhydrous silicic acid is particularly preferable. As the monodispersed spherical powder, a spherical powder having a particle size distribution can be classified to be monodispersed, or already classified and marketed can be purchased and used. Preferred examples of commercially available products include “KP545 / SA-monodispersed spherical silica” (monodispersed silicic acid anhydride having a particle size of 3 μm). Such powder, when present on a plate-like powder, embodies a fresh luster. In this case, if spherical powders having different particle diameters exist, this effect is reduced. Therefore, 90% by mass or more, more preferably 95% by mass or more of the spherical powders are monodisperse particles having the same particle diameter. It is preferably composed of spherical powder.
