Description

Technical Field

[0001] The present invention relates to powdered cosmetics.

Background Art

[0002] Powdered cosmetics such as face powder used for finishing makeup are used for the purpose of absorbing sebum and sweat to prevent makeup from smudging, for the aesthetic effect of diffusing light to make the skin look three-dimensional, and for the purpose of imparting a soft focus effect that blurs pores.

[0003] In order to obtain a smooth feeling of use (also referred to as a smooth feeling), such powdered cosmetics contain a large amount of powder components such as plate-shaped powders such as mica and talc that have the effect of absorbing sebum and sweat, and spherical powders that have the effect of diffusing light. Also, in order to uniformly adhere the powder components to obtain a good finish, the composition of the powder components has also been studied (for example, Patent Documents 1 and 2 below).
