CAS: 84380-01-8 Molecular Formula: C12H16O7 Description Alpha-Arbutin is the more effective, faster and safer approach to skin lightening. It lightens the color of the skin more efficiently and effectively than do existing single components Properties: Alpha-arbutin blocks epidermal melanin biosynthesis by inhibiting enzymatic oxidation of Tyrosine and Dopa. It acts faster and more efficient than do existing single components. Function: *Promotes lightening and an even skin tone on all skin types. *Minimizes liver spots. *Can reduce the degree of skin tanning after UV exposure. Cosmetic application: *All degrees of skin lightening. Formulations: Alpha-arbutin is a water soluble, crystalline, white powder which is easily incorporated into the water phase of cosmetic formulations. Alpha-arbutin is stable against hydrolysis as tested in the pH range from 3.5 to 6.5. Suggested concentration 0.2% when formulated with an exfoliant or penetration enhancer, otherwise up to 2%. In-vitro test: Alpha-arbutin exhibits impressive in-vitro tyrosinase inhibition on human cell lysate (IC50 = 1.0 mMol) as compared to Beta-Arbutin (IC50 = 9.0 mMol). 500g, 1kg/bag
