Glabridin

Glabridin (CAS 59870-68-7) is the primary bioactive isoflavonoid extracted from licorice root, where it occurs as the dominant polyphenol in the hydrophobic fraction. In commercial formulation, it functions as a skin-brightening active and antioxidant. This compound serves as a UV-stabilizing ingredient across cosmetic and pharmaceutical product lines. In topical skincare, it is formulated into serums, creams, and spot-treatment products targeting hyperpigmentation and uneven skin tone.

The ingredient inhibits melanin synthesis pathways relevant to cosmetic efficacy claims. Suncare formulators incorporate it as a secondary UV-stabilizing component alongside primary filters to improve photostability of finished SPF products. In functional food and nutraceutical applications, it is used in antioxidant-positioned supplements and standardized licorice extracts. Buyers require documented polyphenol content for these specific health and wellness applications.

Pharmaceutical researchers and contract manufacturers source it as a reference standard or active ingredient for topical dermatological preparations. It is supplied as an off-white to pale yellow powder for various industrial uses. The material is typically standardized to 90%, 95%, or 98% purity by HPLC. It is available in both cosmetic-grade and research-grade specifications, with documentation suited to EU cosmetic regulation dossiers or pharmaceutical development files.

Packaging ranges from small quantities for R&D through to kilogram-scale lots for commercial formulation. Our supply chain ensures consistent quality and purity levels that meet rigorous international manufacturing requirements.
