METHOD FOR PRODUCING STABLE EMULSIFIED NANOPARTICLE USING ARBUTIN AND COSMETIC COMPOSITION CONTAINING EMULSIFIED NANOPARTICLE

摘要

PROBLEM TO BE SOLVED: To obtain an emulsified nanoparticle having excellent biocompatibility and physicochemical stability and several to several hundred nanometer size, and to obtain a cosmetic composition containing the same.;SOLUTION: A method for producing the cosmetic composition having excellent biocompatibility and physicochemical stability comprises adding arbutin of 0.001-20 times as much as the total weight of lecithin to produce an emulsified nanoparticle, including and collecting a physiologically active substance in the emulsified nanoparticle in the production and making the composition contain 0.0001-90 wt.% of the emulsified nanoparticle.;COPYRIGHT: (C)2005,JPO&NCIPI
