Product name: alpha-Arbutin Synonyms: Arbutin, α-Arbutin INCI name: alpha-Arbutin CAS No.: 84380-01-8 EINECS: 209-795-0 Quality: assay 99.5% up by HPLC Molecular formula: C12H16O7 Molecular weight: 272.25   Description: Extracted from plants such as bearberries, blueberries, and cranberries, alpha arbutin is a safe skin brightening ingredient which helps to fade scars and pigmentation left behind by breakouts and sun damage. Alpha arbutin is frequently marketed as a safer alternative to hydroquinone (a popular skin-lightening ingredient that has been banned in Europe and Australia). It has similar results in brightening skin but without the dangerous bleaching process. Instead, it reduces skin’s pigment production by suppressing the enzymes that stimulate melanin. This also slows down the process by which UV light causes pigmentation, so it both prevents and treats pigmentation issues.    Specification (assay 99.5% up by HPLC): Item Specification Appearance White crystalline powder Assay ≥99.5% Melting point 201 to 207±1℃ Clarity of water solution Transparency, colorless, none suspended matters.
