11,14-Eicosadienoic acid, (11Z,14Z)-

11,14-Eicosadienoic acid (CAS 5598-38-9), also referred to as Homo-Gamma-Linoleic Acid or Delta11,14-Eicosadienoic acid, is a C20 polyunsaturated fatty acid with two methylene-interrupted cis double bonds. It belongs to the omega-6 fatty acid family and is structurally related to linoleic acid, extended by two carbon units.

In pharmaceutical and nutraceutical formulations, Homo-Gamma-Linoleic Acid serves as a bioactive lipid component where its conjugated double-bond geometry supports antioxidant activity by scavenging reactive oxygen species within lipid matrices. In cosmetic emulsions, it contributes to membrane fluidity and oxidative stability of fatty acid blends, helping to protect sensitive active ingredients from degradation.
