Alpha Arbutin (4- Hydroxyphenyl-α-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. | ||||||||
Cosmetic Raw Materials Arbutin Powder 99%/Alpha Arbutin/Beta Arbutin
Arbutin is commercially used as a skin-whitening agent in cosmetic industry. It works by competitive inhibition of the enzyme, tyrosinase, a key enzyme in the synthesis of melanin. Depending on the spatial structure of the glycosidic linkage between glucose and hydroquinone, arbutin forms two epimers: Alpha Arbutin and Beta arbutin.

Arbutin Working Mechanism
Skin whitening:Arbutin exhibits potent melanin-inhibiting properties and confers whitening effects on the skin. Sun damage and injury or inflammation to the skin from acne, eczema or psoriasis are the two main factors that cause melanin production on the skin. Arbutin can reduce the accumulation of pigment by inhibiting the production of melanin, which accumulates on the skin when tyrosine is oxidized. An enzyme called tyrosinase is the catalytic for this reaction. Scientists found arbutin has shown inhibitory actions against tyrosinase. When topically apply skincare products containing Arbutin, the inhabitation of tyrosinase results in the decrease of melanin, thus, a whiter complexion.
Hyperpigmentation in the epidermis is caused by excessive melanin synthesis due to UV irradiation, wound or stress. Tyrosinase is one of the key enzymes involved in melanin synthesis. The enzyme catalyses the first two steps in melanin synthesis: the hydroxylation of tyrosine to DOPA and the oxidation of DOPA to dopaquinone. Arbutin has an direct inhibitory function against tyrosinase, which leads to the prevention of melanin formation and a whitening effect on the skin.

Alpha Arbutin is enzymatically synthesized from hydroquinone and saccharides through transglycosylation reaction. Various carbohydrate-active enzymes such as α-amylase, α-glucosidase, transglucosidase, sucrose phosphorylase, and dextransucrase have been employed to synthesize Alpha Arbutin. It is one of the most advanced skin lightening ingredients on the market.
