  • Applications

    5,8,11,14,17-Eicosapentaenoic Acid (EPA, CAS 1553-41-9) is primarily used as an omega-3 fatty acid ingredient in nutraceuticals and pharmaceutical formulations. It is commonly considered for food processing applications as a dietary supplement or fortifying ingredient to raise omega-3 content in products. In cosmetics and personal care, EPA and its lipid derivatives are evaluated as emollients or conditioning lipids in lipid-rich formulations. In agriculture/animal nutrition, EPA can be employed as a feed additive to improve the fatty acid profile of farmed animals and aquaculture products. In industrial contexts, EPA may serve as a lipid-based intermediate for synthesis of esters or specialty polymers and coatings, subject to formulation limits and regulatory requirements.
