Description

  The present invention relates to a liquid skin cosmetic composition containing a powder.

  Skin cosmetics containing powder are widely used for the purpose of absorbing dirt, sebum, sweat and the like on the skin into powder and improving the feeling of use. Examples of such powder-containing cosmetics include liquid or gel-like cool cosmetics containing a cationic thickener, a cooling agent and ethanol (Patent Document 1), and crosslinked (meth) acrylic acid having a certain compressive strength Gel cosmetics containing an ester-based resin powder (Patent Document 2) and the like have been reported.
