Overview
Deoxyarbutin (d-Arbutin) is a synthetic derivative of hydroquinone, designed to offer superior stability and efficacy in skin whitening applications. Unlike natural arbutin, which can degrade into hydroquinone, d-Arbutin maintains its structure under various conditions, making it a preferred choice in cosmetic formulations. It is widely used in anti-pigmentation and brightening skincare products due to its ability to inhibit tyrosinase activity, the enzyme responsible for melanin production. Its synthetic nature ensures consistent performance, and it is often marketed as a safer alternative to hydroquinone.
Physical and Chemical Properties
Deoxyarbutin appears as a white to off-white crystalline powder with a molecular weight of 194.23 g/mol. It is soluble in water, ethanol, and propylene glycol, facilitating its incorporation into aqueous and oil-based formulations. Its melting point ranges between 140-145°C, and it exhibits high stability under normal storage conditions. The compound’s solubility profile and stability make it versatile for use in serums, creams, and lotions.
Main Applications
Deoxyarbutin is primarily employed in the cosmetics industry for skin whitening and brightening products. It is effective in reducing hyperpigmentation, age spots, and melasma by inhibiting melanin synthesis. Beyond cosmetics, it finds limited use in pharmaceuticals for topical treatments targeting pigmentation disorders. Its non-irritating properties make it suitable for sensitive skin formulations, often combined with other active ingredients like vitamin C or niacinamide.
Safety and Storage
Deoxyarbutin is generally considered safe for topical use at concentrations up to 3%. However, prolonged exposure to high concentrations may cause skin irritation, and it should be avoided in eye-area products. Proper storage involves keeping the compound in a cool, dry place, protected from light and moisture to prevent degradation. Bulk quantities should be stored in airtight containers with desiccants to maintain stability.
B2B Procurement Guide
When procuring deoxyarbutin, prioritize suppliers with certifications such as GMP or ISO to ensure quality and consistency. Request certificates of analysis (CoA) verifying purity (≥98%) and absence of contaminants like heavy metals or residual solvents. Pricing varies based on quantity and supplier, with bulk purchases (10+ kg) often discounted. Consider testing small batches for compatibility with your formulations before large-scale procurement. Reliable suppliers typically provide stability data and technical support for formulation integration.
