Abstract
A water-releasing cosmetic makeup material that has excellent stability, exhibits good dispersion of color pigments, and ruptures smoothly upon application to provide good spreadability and superior feeling. The water-releasing cosmetic makeup material is formed of a water-in-oil emulsion comprising (a) a partially crosslinked polyether-modified silicone, a partially crosslinked polyglycerin-modified silicone, or a combination thereof, (b) an acrylic silicone-based graft copolymer, and (c) a branched silicone surfactant in an amount of 0.05 to 0.7% by mass.
