11,14-Eicosadienoic acid

11,14-Eicosadienoic acid (CAS 2091-39-6) is a straight-chain C20 polyunsaturated fatty acid with two cis double bonds at positions 11 and 14, commonly abbreviated as 20:2(11Z,14Z). It carries no assigned E-code and is not classified under a standard food additive designation. It is also referenced in literature as eicosa-11,14-dienoic acid.

In food and nutrition applications, 20:2(11Z,14Z) functions as an antioxidant stabilizer by integrating into lipid matrices and moderating oxidative chain reactions, helping to extend the stability of fatty acid blends. In pharmaceutical and personal care formulations, it serves as a bioactive fatty acid component, where its specific double-bond geometry influences membrane fluidity and skin-barrier interactions at the cellular level.

This material is supplied as a liquid and is available for procurement subject to REACH compliance requirements applicable within the European Economic Area. Buyers should confirm grade specifications, purity certificates, and packaging formats directly with the supplier to align with FCC or internal quality standards.
