Abstract
Numerous novel ingredients have been introduced for the higher functionality of whitening cosmetics. Through the preliminary research, we have found Trichosanthes kirilowii root, Prunella vulgaris leaf and Clematis chinensis root have high whitening efficacy. But they are insoluble. Moreover the discoloration of and decrease in content take place when they are exposed to light, heat or oxygen. From Trichosanthes kirilowii root, Prunella vulgaris leaf and Clematis chinensis root, efficacious ingredients were ethanol-extracted by heating to 75∼85$^{\circ}C$ for 6∼8 h. These extracts have the inhibitory activity of tyrosinase and B16 melanin formation, thus enhancing whitening effect. We made liposomes using propylene glycol (PG)/hydrogenated lecithin/middle chain triglycerides (MCT)/glycerin/water and microfuidizer to stabilize extracts. The stability against heat and light was enhanced by 3∼5 times compared with untreated extracts. Particle size analyzer, freeze fracture transmission electron microscopy (FF-TEM), chromameter and HPLC are used for the analysis.
