Alpha Arbutin

INCI Name: Alpha Arbutin

CAS No.: 84380-01-8

EINECS No.: 440-470-8

Molecular Formula: C12H16O7

Alpha-Arbutin, similar to Arbutin, inhibits the production and deposition of melanin. It inhibits the activity of tyrosinase at

very low concentrations. It inhibits tyrosinase better than Arbutin, rapidly whitening and brightening the skin. It effectively

diminishes spots, protects skin and reduces skin damage caused by UV rays. The dosage is small, the cost is reduced, and the

safety and stability are high. Good compatibility, not affected by temperature, light, etc. in the formulation.

It can effectively inhibits formation of melanin, splash and fleck can be got ride of. so it usually used for skin care, sun care,

skin whitening/lightening, treatment for pigmentary disorders such as age spots etc. The reference addition is 0.2~2%.


Package: Net weight 1.0kg/aluminum foil bag, 10 aluminum foil bags/carton or 25kg / drum

Storage: Keep container tightly sealed. Alpha-arbutin should store in cool, dry conditions in well sealed containers
