EXPEARL
INCI Name : Polymethylsilsesquioxane
EXPEARL are silicone resin powders consisting of polymethylsilesquioxane
(PMSQ) in which Si-O siloxane groups are three-dimensionally bonded into
CH3SiO3/2. Due to their lower refractive index (~1.43) than other powder-type
products, EXPEARL series show improved hiding power on skins.
