WATER-IN-OIL EMULSION COMPOSITION CONTAINING HYDROPHOBIC SPHERICAL SOL-GEL SILICA MICROPARTICLE

摘要

To provide a water-in-oil emulsion composition that has excellent storage stability without using a surfactant, and also has excellent safety, and is useful for cosmetics, skin preparations or the like.SOLUTION: A water-in-oil emulsion composition contains (a) an oil phase component 100 pts.mass, (b) an aqueous phase component 11-800 pts.mass, and (c) hydrophobic spherical sol-gel silica microparticles with a volume median size (D50) of 5-1500 nm 0.5-40 pts.mass.SELECTED DRAWING: None
