Description

The present invention relates to a water-in-oil emulsion composition.

Base make-up cosmetics such as foundations are preferred for their basic function of covering up skin defects such as blemishes, as well as producing a natural skin feel. In addition, there is a demand for products imparted with an ultraviolet protection function.
Base makeup cosmetics usually contain powders such as pigments. In order to stably blend these powders and improve adhesion to the skin, a water-in-oil emulsifier type, in which an oily component is present in the continuous phase, is likely to be adopted as the dosage form.

The powder aggregates in the dosage form, and when applied, white streaks and uneven application may occur, impairing the finish of makeup, which is regarded as a problem. In addition, while the pigments of the powder are responsible for the covering power, they may cause powderiness and whitening, and such unnatural makeup tends to be avoided, so a natural finish is recommended. There is a demand for cosmetics that produce effects. In order to solve these problems, it has been proposed to use a specific oil agent, or to use a coloring pigment or extender pigment subjected to a specific coating treatment (Patent Documents 1, 2, etc.).
