Description

Technical Field

[0001] This invention relates to water-in-oil emulsion cosmetics. Background Technology

[0002] Previously, in cosmetics such as foundation, water-in-oil emulsion cosmetics containing coloring materials were used (for example, Patent Document 1). In such cosmetics, for example, by using thickeners or the like, the viscosity of the aqueous phase is maintained within a specific range, allowing the coloring material to be dispersed in the aqueous phase, but there is room for improvement in the skin-friendly feel when applying.
