α Arbutin, White crystal powder, easily soluble in water,methanol,ethanol,propylene glycol, glycerin without precipitates. Alpha Arbutin also known as 4-Hydroxyphenyl-alpha-D-glucopyranoside, is mainly used to bind to tyrosinase of melanocytes in the skin and inhibit tyrosinase activity. It’s a popular whitening agent in Japan and other asian countries.   It mainly use in cream,essence,facial mask for whiten skin and frechles removal. And the ability of α-arbutin to inhibit this enzyme ( whitening effect) is 10 to 15 times than of β-arbutin.

The whitening Mechanism of Alpha Arbutin

The content and distribution of melanin are the main factors that determine the depth of skin color. Melanin is produced in melanocytes in the basal layer of the skin epidermis. It is finally formed from tyrosine under the action of tyrosinase through a series of complex biochemical reactions. It is transferred from the basal layer to the outer layer of the epidermis from the inside out through synapses. Color the skin.

Tyrosinase has tyrosine hydroxylase activity (catalyzing tyrosine to produce dopa) and dopa oxidase activity (catalyzing dopa to produce dopaquinone). In the process of melanin formation, it serves as the main rate-limiting enzyme. Its activity determines the amount of melanin formed.

Arbutin is a tyrosinase inhibitor that can effectively inhibit tyrosinase activity without affecting cell proliferation concentration. It competes for the binding of dopa through its direct binding to tyrosinase. site, blocks the synthesis of dopa and dopaquinone, thereby interfering with melanocytes and inhibiting the production of melanin. At the same time, it also has the function of diluting formed melanin, accelerating the decomposition and excretion of melanin, reducing skin pigmentation, and removing spots and freckles.
