MODIFIED SURFACE MODIFIER, METHOD FOR PRODUCING THE SAME, METHOD FOR SURFACE-MODIFYING POWDER WITH THE MODIFIER, AND COSMETIC CONTAINING THE MODIFIED POWDER

摘要

PPROBLEM TO BE SOLVED: To provide a modified surface modifier obtained by substituting, with alkoxy groups, the hydrogen atoms of Si-H bonds present in the molecular chain of a copolymer produced by copolymerizing methylhydrogenpolysiloxane with dimethylpolysiloxane, to provide a method for producing the same, to provide a method for surface-modifying a powder with the same, and a cosmetic formulated therefrom. PSOLUTION: The modified surface modifier represented by general formula (I) (wherein Me is a methyl group; OR is an alkoxy group; m is an integer of 1-350; and n is an integer of 1-350) and the method for producing the same are provided.
