Description

6-o-Galloyl Arbutin is a specialized, high-purity derivative of arbutin, where a galloyl moiety is esterified to the glucose unit. This molecular modification significantly enhances its antioxidant and tyrosinase-inhibiting properties compared to standard arbutin, making it a highly effective active for advanced skin-brightening formulations. It is primarily sought after by R&D and production teams in the global cosmetic, personal care, and pharmaceutical industries for developing premium skincare products targeting hyperpigmentation and photoaging.

Application

• Premium Skin Brightening & Whitening Cosmetics: A key active ingredient in serums, creams, and lotions designed to reduce the appearance of dark spots, melasma, and uneven skin tone.
• Anti-Aging & Antioxidant Formulations: Used in products aimed at protecting skin from oxidative stress and environmental damage, helping to prevent signs of premature aging.
• Pharmaceutical Topical Preparations: Incorporated into medicated creams or gels for conditions associated with hyperpigmentation, leveraging its potent tyrosinase inhibition.
• Functional Personal Care Products: Found in high-end cleansers, toners, and masks that offer targeted treatment benefits beyond basic cleansing.
• Cosmeceutical R&D: Serves as a reference standard and active component in research for novel dermal delivery systems and efficacy studies.

Quality Control

Our 6-o-Galloyl Arbutin is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards suitable for cosmetic and pharmaceutical applications. A comprehensive Certificate of Analysis (COA) detailing purity, residual solvents, and heavy metals is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is easily oxidized; for long-term storage, keeping the container under an inert atmosphere (e.g., nitrogen) is recommended to maintain optimal stability and potency.
