Abstract: The present invention has the purpose of providing an oil-in-water emulsion cosmetic that contains a high quantity of an ultraviolet absorbing agent and an ultraviolet scattering agent in the oil phase and achieves a high SPF, while simultaneously having a Distinctive fresh feeling in use when applied to the skin. The present invention provides an oil-in-water emulsion cosmetic characterized by comprising (A) 0.05 to 1% by mass of a hydrophobically modified alkyl cellulose; (B) 5 to 40% by mass of an oil component; (C) 2.5 to 30% by mass of an ultraviolet scattering agent having a hydrophobic surface; and (D) a water phase thickener having low salinity tolerance; wherein the (C) ultraviolet scattering agent is dispersed in the oil phase.

Abstract: The present invention relates to a water-based cosmetic wherein a hydrophobic powder is directly dispersed in the water phase of the water-based cosmetic, the water-based cosmetic having the excellent smoothness, water resistance and cosmetic durability characteristic of hydrophobic powders, while maintaining the refreshing sensation of use that is inherent in water-based cosmetics.The invented water-based cosmetic is characterized by comprising: (A) 0.1 to 5 mass % of a polyether-modified silicone having an HLB (Si) of 5 to 14; (B) one or more hydrophilic thickeners; (C) a polyol and/or an ethyl alcohol; and (D) one or more hydrophobic powders chosen from among metal oxides hydrophobically treated without using a metal soap, hydrophobic organic powders and silicone powders; wherein the (D) hydrophobic powder is dispersed in the water phase.
