PROBLEM TO BE SOLVED: To provide a water dispersion composition containing inorganic oxide microparticles and a salt, the water dispersion composition being highly dispersed in the condition where properties of the inorganic oxide microparticles are maintained without spoiling, and to provide a water system cosmetic containing the water dispersion composition. ! SOLUTION: The water dispersion composition of the invention contains a salt and surface modification inorganic oxide microparticles, where the surface of an inorganic oxide microparticles with a mean particle diameter of 200 nm or less is modified with a polyglycerol chain. As the salt, an alkali metal salt is preferable. And as the inorganic oxide, at least one kind selected from titanium oxide, silicon oxide, aluminium oxide, zirconium oxide, and zinc oxide is preferable. ! COPYRIGHT: (C)2015,JPO&INPIT |
