  • Applications

    Tricin (CAS 520-32-1) is a natural flavone explored as an antioxidant and potential UV-absorbing additive in cosmetics and personal care; it is evaluated as a stabilizer for polymers, plastics, and coatings to improve durability and shelf life; in coatings and inks, tricin may serve as a stabilizer or UV-protective component; in cleaning formulations, it is studied as an antioxidant additive for formulation stability; and in agricultural or biomaterials research, it is considered a plant-derived metabolite with potential uses in crop protection or the development of bio-based materials.
