Abstract:
An emulsified cosmetic offering superior sensation of use and r stability comprises 0.1 to 25 wt % of aqueous moisturizing components, 2 to 80 wt % of oil solution components, and 0.1 to 30 wt % of spherical resin particles having hydrophilic groups on their surfaces and an average volume particle size of 2.0 μm to 20.0 μm. The spherical resin particles are made by applying alkali cleaning or acid cleaning to aggregation particles after resin polymerization, and the volume particle size distribution GSDv of the spherical resin particles is 1.3 or less, and the shape factor SF1 thereof is 100 to 140.
