Description

  The present invention relates to a skin cosmetic composition, and more particularly, to a skin cosmetic composition that is excellent in a smooth feeling when applied to the skin and an effect of suppressing skin shine, and excellent in redispersibility. .

  The so-called T zone, which extends from the forehead to the nose, has a large amount of sebum secretion, and is particularly a part that feels sticky and sticky for people with oily skin. Conventionally, skin cosmetics such as lotion have been used for the purpose of supplementing the skin with moisture, etc., but for those people with oily skin, skin with a smooth feeling and sebum-suppressing effect. Cosmetics are desired. Conventionally, a technique for blending powders (for example, see Patent Documents 1 and 2) and a technique for blending a combination of two kinds of powders (for example, patents) in order to enhance the smoothness and sebum suppression effect of skin cosmetics. (Refer to References 3 to 4), a technique for blending a polyvalent metal compound having an astringent effect (for example, see Patent Document 5), etc. has been reported. There was a problem that the feeling and sebum suppression effect could not be sufficiently obtained. In order to improve the smooth feeling and sebum suppression effect, aqueous dispersion skin cosmetics containing both powder and polyvalent metal compounds are effective. Such skin cosmetics contain caking (contained). The solidified powder solidifies on the bottom surface in the liquid phase and does not disperse even when shaken), resulting in a problem of poor redispersibility.

Therefore, for the purpose of improving the redispersibility, there have been reported methods of blending 60% or more of ethanol into skin cosmetics or making skin cosmetics into non-aqueous aerosols (for example, patents). From the viewpoint of skin irritation and global warming, skin cosmetics are desired to be ethanol-free and non-aerosol type as much as possible.
Therefore, an aqueous dispersion skin cosmetic containing a powder and a polyvalent metal compound is desired, and a technique capable of improving redispersibility while maintaining a smooth feeling and sebum suppression effect is desired. This is the current situation.
