Description

  The present invention relates to a water-in-oil emulsified cosmetic.

In makeup cosmetics, it is required to finish the skin with natural transparency, color development and gloss while correcting skin defects such as uneven color and unevenness. Conventionally, pearl pigments such as mica and mica titanium have been used to give gloss to makeup cosmetics.
For example, Patent Document 1 discloses that a makeup cosmetic containing a specific composite powder such as titanium mica and a flaky powder such as boron nitride corrects skin defects and provides a natural transparent and glossy skin. It is described that it is excellent in usability with light finish, light spread and adhesion to the skin.
