Description

Flake powder for controlling oil and keeping make-up, preparation method and make-up powder cosmetic Technical Field The application belongs to the technical field of cosmetics, and particularly relates to a flaky powder for controlling oil and keeping make-up, a preparation method and a make-up powder cosmetic. Background During makeup, makeup is usually performed by applying foundation liquid, fixing the makeup by using powder cosmetics such as loose powder, powder cake and the like, and the powder cosmetics can reduce makeup removal and maintain the makeup. However, in conventional make-up powder cosmetics such as loose powder and cake, there are used various components such as flake powder such as mica powder, talc powder and kaolin, spherical powder such as oil-controlling silica and coloring agent, and the like, and the flake powder in the make-up powder cosmetics can bring about good skin adhesion, but the surface texture is not as high as that of the spherical powder, and the surface texture is not as high as that of the spherical powder, resulting in general physical adsorption of oil and oil-controlling properties, and although the oil-controlling ability of the make-up powder cosmetics can be improved by adding a large amount of high oil-controlling powder raw material of the spherical powder such as silica, the content of the spherical powder such as silica is high, which leads to the situation that the make-up effect is dry, and the powder compactability is poor or the powder is easy to fly.
