What is 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.
Where is Glabridin used?
- Cosmetic formulation: skin-brightening active and antioxidant
- Cosmetics and pharmaceuticals: UV-stabilizing ingredient
- Topical skincare: serums, creams, and spot-treatment products targeting hyperpigmentation and uneven skin tone
- It inhibits melanin synthesis pathways relevant to cosmetic efficacy claims.
- Suncare: secondary UV-stabilizing component alongside primary filters to improve photostability of finished SPF products
- Functional food and nutraceuticals: antioxidant-positioned supplements and standardized licorice extracts
- Pharmaceuticals: reference standard or active ingredient for topical dermatological preparations
Good to know: Buyers require documented polyphenol content for health and wellness applications. The material is typically standardized to 90%, 95%, or 98% purity by HPLC, with cosmetic-grade and research-grade specifications and documentation suited to EU cosmetic regulation dossiers or pharmaceutical development files.
