Description

  The present invention relates to an oily solid cosmetic.

  Conventionally, in oily solid cosmetics such as stick lipstick, various composite powders and the like have been used in order to obtain a smooth spread. For example, Patent Literature 1 describes a cosmetic containing an organopolysiloxane elastomer spherical powder and an ultraviolet absorber and / or an ultraviolet scattering agent. Patent Literature 2 discloses a composite powder composed of different kinds of organopolysiloxanes. And cosmetics containing a partially crosslinked organopolysiloxane polymer.
