Abstract:
The present invention provides a method for preparing porous organic/inorganic composite powder which includes attaching inorganic oxide nanoparticles in a multi-layer form by repeating steps of attaching polyphenol to porous polymethyl methacrylate (PMMA) microspheres and attaching inorganic oxide nanoparticles to the porous polymethyl methacrylate (PMMA) microspheres to which polyphenol is attached, and a cosmetic composition including the porous organic/inorganic composite powder.
