Abstract

|
Recently, arbutin, oil soluble licorice extact (GLY), ascorbyl glucoside (AA2G), and ethyl ascorbyl ether (EAE) have been widely used as functional whitening ingredients. To Investigate which combination between the above agents could be more effective for whitening effect, tyrosinase activity and MSH-induced melanin production in B-16 melanoma cells were investigated. Both GLY and arbutin dose-dependently inhibited purified tyrosinase activity. The inhibitory effects of GLY with AA2A or EAE on Drosinase activity were more potent than those of GLY alone, whereas that of arbutin with other ingreadients did not show those effects. In MSH-induced melanin production in B-16 melanoma cells, the mixture of Gly and EAE more significantly reduced melanin formation than Gly alone. Stability of mixture of GLY, arbutin, AA2A and EAE exposed at the temperature of 25^{circ}C;or;45^{circ}C for 30 days were also investigated. All of the combinations of whitening agents did not show any critical changes in their composition stability. These data suggest that the combination of GLY and vitamin C derivatives such as AA2G and EAE may be useful for the promotion of whitening effect.
