Description

The present invention relates to solid powder cosmetics.

Zinc oxide and titanium oxide are used in cosmetics for UV protection. However, when these zinc oxide and titanium oxide are simply added to cosmetics and used, they do not spread well, so they are used in combination with organic spherical powder for practical use.
For example, in Patent Document 1, a cosmetic containing a composite powder in which 60% or more of inorganic powder particles of titanium oxide or zinc oxide is supported on the surface of an organic spherical powder is excellent in UV shielding effect and spreads on the skin. It is described that it spreads well and gives a natural finish. Further, in Patent Document 2, a powder cosmetic containing spherical zinc oxide or spherical powder to which fine particles of zinc oxide are adhered spreads well on the skin, makes pores and fine wrinkles inconspicuous, and can be applied to the skin. It is described as having excellent durability. Furthermore, in Patent Document 3, a solid cosmetic for correcting unevenness containing a composite powder in which the surface of (vinyl dimethicone/methicone silsesquioxane) crosspolymer particles is coated with zinc oxide has an unevenness correcting effect and skin transparency. It is described that the feeling and feeling of use are excellent.
