Description
Eicosapentaenoic Acid (EPA, CAS 10417-94-4) is a long-chain omega-3 fatty acid commercially available under trade names including Icosapent and Ropufa 70, and abbreviated in formulation contexts as C20:5 omega-3. It carries no assigned E-code and is classified under organic acids with EC number 600-528-7.
In food and nutrition applications, EPA functions as a flavorant and emulsifier, contributing to lipid dispersion stability in fortified products and omega-3 enriched emulsions. In personal care formulations, it acts as an emollient and skin conditioner by integrating into the lipid barrier, and its surfactant properties support surface wetting and ingredient delivery in topical systems.
EPA is supplied as a pharmaceutical-grade or food-grade material, with compliance referenced against Ph.Eur. monographs and FCC standards depending on end use. It falls under REACH regulation and is classified under HS code 29161900. Packaging formats typically include drums and smaller containers suited to pharmaceutical and specialty nutrition procurement volumes.
