Application: Arbutin(497-76-7) is used as diuretic in medical, ARBUTOSIDE can also be
used as material in cosmetics, which have the effect of whitening, remove spots, hair
care, etc. It can infiltrate into the skin quickly without affecting the concentration of cell multiplication and effectively prevent activity of tyrosinase in the skin and the forming of melanin.
