Abstract:
PURPOSE: A cosmetic composition containing nanoparticles is provided to ensure colloid stability and to enable safe biodegradation in vivo. CONSTITUTION: A nanopaticle is prepared by impregnating physiologically active ingredients into amphiphilic polymers of a sterostructure comprising a core part with a plurality of branches formed of hydrophobic polymers and an arm part formed of hydrophilic polymers. The hydrophobic polymers are is a copolymer formed of poly-carprolactone, poly-L-lactic acid, poly-D,L-lactic acid, poly-D-lactic acid-co-glycolic acid, poly-L-lactic acid-co-glycolic acid, poly-D,L-lactic acid-co-glycolic acid, or monomer thereof. A cosmetic composition contains the nanoparticles as an active ingredient.
