Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a makeup cosmetic such as a foundation, and more particularly to a makeup cosmetic such as a particle size of 0.1.
The present invention relates to a makeup cosmetic containing a plate-like powder having a particle size of 5 to 50 μm coated with a spherical powder of 1 to 1 μm and a spherical silica containing a powder having a refractive index of 1.8 or more. The present invention relates to a makeup cosmetic which is excellent in the effect of concealing pores and fine wrinkles, and at the same time, gives the skin a gloss with a natural finish and is also excellent in the persistence of the cosmetic effect.

[0002]

2. Description of the Related Art Makeup cosmetics are originally cosmetics for imparting a desirable color to the skin.
There is a demand for not only simply imparting a favorable color, but also concealing pores and fine lines, which are undesirable parts of the skin, in a natural feeling. For this reason, many techniques for concealing skin defects with a natural finish have been developed. Specifically, powder with high light diffusion effect such as spherical silica is blended, technology to blur pores and fine wrinkles, powder with high refractive index such as titanium oxide is blended at high concentration, and the whole skin including pores is A technique for concealment and the like are included.

[0003]

However, spherical powders such as spherical silica having a light diffusing effect, such as spherical silica, can provide a soft matte finish, but in order to hide pores and fine lines, it is necessary to mix them at a high concentration. Therefore, there was a defect that the decorative film became dull. In addition, since spherical powders such as spherical silica have a property of easily gathering in pores, the pores are not conspicuous immediately after application, but over time, they become wet with sebum and sweat and the pores become more conspicuous. Had also. For this reason, a technique has been developed in which a spherical powder surface is surface-treated with a fluorine compound to impart a water- and oil-repellent treatment. However, these surface-treated powders have poor skin familiarity, In some cases, the powder was lifted from the surface. On the other hand, when a powder having a high refractive index is blended at a high concentration, not only the pores and fine wrinkles are hidden but also the entire skin is hardly hidden, which may result in an unnatural finish.

[0004]

Under these circumstances, the present inventors have conducted intensive studies and as a result, the plate-like powder coated with the spherical powder has a problem that the plate-like powder is less likely to cause specular reflection and transmitted light scattering. It has been found that the light scattering effect of the spherical powder can provide an effect of blurring pores and fine wrinkles and a natural luster to the skin. On the other hand, spherical silica encapsulating a powder with a high refractive index has the property of gathering in pores and fine wrinkles like conventional spherical powder, but even when wet with sebum or sweat, it does not become transparent, It has been found that the effect of hiding pores and fine wrinkles is maintained because the color of the encapsulated powder is developed. And make-up cosmetics containing both are superior in the effect of concealing pores and fine wrinkles on the skin, but at the same time, with a natural finish, give the skin a luster, and find that the persistence of the cosmetic effect is more excellent, The present invention has been completed.

That is, the present invention relates to the following components (a) and (b): (a) a plate-like powder having a particle diameter of 5 to 50 μm coated with a spherical powder having a particle diameter of 0.1 to 1 μm (b) An object of the present invention is to provide a makeup cosmetic containing spherical silica containing a powder having a refractive index of 1.8 or more. The makeup cosmetic, wherein the content of the component (a) is 0.5 to 40% by mass and the content of the component (b) is 0.1 to 20% by mass, and the particle size of the component (b). Any of the above-mentioned makeup cosmetics, wherein the spherical powder of the component (a) is silica, and the above-mentioned makeup cosmetic, wherein the spherical powder of the component (a) is silica. The present invention provides makeup cosmetics.
