Alpha-arbutin powder 99%
Factory Directly Provide Alpha-Arbutin Powder
What's 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.
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.
Function&Application:
1. alpha-arbutin powder is applied in cosmetic field.
(1) Alpha arbutin powder can protect the skin against damage caused by free radicals.
(2) Alpha arbutin powder is a skin whitening agent which is very popular in Japan and Asian countries for skin de-pigmentation.
(3) Alpha arbutin powder inhibits the formation of melanin pigment by inhibiting Tyrosinase activity.
(4) Alpha arbutin powder is very safe skin agent for external use which does not have toxicity, stimulation, unpleasant odor or side effect such as Hydroqinone.
(5) Alpha arbutin powder mainly gives three main properties; Whitening effects, anti- age effect and UVB/ UVC filter .
2. alpha-arbutin powder is applied in medical field.
(1) Alpha arbutin powder was first used in medical areas as an anti-inflammatory and antibacterial agent.
(2) Alpha arbutin powderwas used particularly for cystitis, urethritis and pyelitis.
(3) Alpha arbutin powder may be used to repress the virulence of bacterial pathogens and to prevent contaminating bacteria.
(4) Alpha arbutin powder is used for treating allergic inflammation of the skin .
(5) Alpha arbutin powder has been used to prevent pigmentation and to whiten the skin beautifully.
(6) Alpha arbutin powder can be used to whiten the skin, to prevent liver spots and freckles, to treat sunburn marks and to regulate melanogenesis.
