Description
Moroctic acid (CAS 20290-75-9), also known as stearidonic acid or 18:4(n-3), is a polyunsaturated omega-3 fatty acid of the C18 series. It carries no assigned E-code and is referenced in chemical databases under the identifier CHEBI:32389. It occurs naturally in certain plant seed oils, including blackcurrant and hemp seed oil.
In food and nutrition applications, stearidonic acid serves as a metabolic precursor to longer-chain omega-3 fatty acids, offering formulators a plant-derived route to omega-3 enrichment in functional foods and dietary supplements. In personal care formulations, its antioxidant activity supports lipid stability in emollient systems, helping to slow oxidative degradation of oil-phase ingredients.
Moroctic acid is supplied as a liquid at ambient conditions. Procurement teams should confirm compliance with REACH registration requirements for EU import and use. Relevant purity specifications vary by application, with food and pharmaceutical grades subject to additional documentation; buyers are advised to request a certificate of analysis and safety data sheet.
