Arctostaphylos Extract Cosmetic Raw Material 98% Beta-Arbutin Powder CAS 497-76-7
What is Beta-Arbutin?
β-Arbutin is a common skin-whitening ingredient; chemically, it is a glucoside derivative of hydroquinone that inhibits melanin production by suppressing tyrosinase activity.
Its chemical name is 4-hydroxyphenyl-β-D-glucopyranoside, with the molecular formula C₁₂H₁₆O₇ and CAS number 497-76-7. It appears as a white crystalline powder, is readily soluble in water, and occurs naturally in plants such as bearberry leaves.
Function
1. Whitening and Spot Fading: Inhibits tyrosinase and blocks melanin production while accelerating the breakdown of existing melanin, helping to fade dark spots and freckles.
2. Improving Skin Tone: Reduces skin pigmentation, resulting in a more even and radiant complexion.
3. Anti-inflammatory Support: Possesses certain bactericidal and anti-inflammatory properties.

For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
