Alpha-Arbutin (4- Hydroxyphenyl-±-D-glucopyranoside) is a pure, water soluble, biosynthetic active ingredient. Alpha-Arbutin blocks epidermal melanin synthesis by inhibiting enzymatic oxidation of Tyrosine and Dopa. Arbutin appears to have fewer side effects than hydroquinone at similar concentrations – presumably due to the more gradual release. It is the more effective, faster and safer approach to promoting skin-brightening and an even skin tone on all skin types. Alpha-Arbutin also minimizes liver spots and meets all the requirements of a modern skin-brightening and skin depigmentation product.Alpha Arbutin exhibits impressive tyrosinase inhibition and is nine times more effective than Beta-Arbutin. Very low IC50 values indicates the power of  Alpha-Arbutin. The outstanding efficacy of Alphar-Arbutin is due to its perfect affinity to the active site of tyrosinase.Alpha-Arbutin is water soluble and easily incorporated into the water phase of cosmetic formulations. It is stable againsthydrolysis as tested in the pH range from 3.5 – 6.6. Suggested concentration: 0.2% when formulated with an exfoliant or penetration enhancer, otherwise up to 2%.
