COMPOSITIONS FOR STABILIZING DIMERIC CINNAMOYLAMIDE DERIVATIVES USING AMPHIPHILIC BLOCK COPOLYMER AND COSMETIC COMPOSITIONS CONTAINING THE SAME

摘要

The present invention relates to stabilization of dimeric cinnamoyl derivatives which are whitening active materials. According to the present invention, provided is a composition for stabilizing the number of dimeric cinnamoyl amide derivatives comprising a nanoparticle composed of a shell for covering a core, by forming the core composed of the dimeric cinnamoyl derivatives and polycaprolactone (PCL) as a hydrophobic block by combination of at least two species of an amphiphilic block copolymer having polyethylene glycol (PEG) as a hydrophilic block.
