The present invention provides an oil-in-water emulsified milky skin cosmetic preparation, which is able to impart a refreshing feeling, an astringent effect, a moisturizing effect, and a softening effect to skin, when it is singlyused, and which is excellent in terms of emulsion stability although it has a high water content and a low viscosity, presenting a milk white color. An oil-in-water emulsified milky skin cosmetic preparation comprising (a) a copolymer of 2-acrylamide 2-methylpropanesulfonic acid or a salt thereof /polyoxyethylenealkyl ether methacrylate, (b) an alkyl modified carboxyvinyl polymer; and (c) an alkylene oxide derivative, and having a viscosity at 25°C of 10,000 mPa·s or less (Vismetron viscometer). It is prefarable that the skin cosmetic preparation comprises 0.005% to 2.0% by mass of (a), 0.005% to 1.5% by mass of (b), and 0.005% to 15.0% by mass of (c). The skin cosmetic preparation may further comprise (d) oil having a viscosity at 25°C of 100 mPa·s or less and being a liquid at an ordinary temperature, arbitrarily. Furthermore, it is prefarable that the skin cosmetic preparation comprises 55% to 80% by mass of water. |
