  • Applications

    Epigallocatechin Gallate (CAS 989-51-5) is used as a natural antioxidant and stabilizing agent across several industries. In cosmetics and personal care, it helps protect formulations from oxidative damage. In food processing and beverages, it is employed as a natural antioxidant to retard oxidation and extend shelf life. In pharmaceutical and nutraceutical settings, it is studied as a polyphenol bioactive ingredient and stabilizer in formulations. In polymers, coatings, and inks, it is investigated as an antioxidant additive to improve aging resistance and support bio-based surface modifications. Applications are typically formulation dependent and subject to local regulations and limits.
