Overview
Eicosatrienoic acid (CAS 17046-59-2 ), also known as Icosatrienoic acid, is a 20-carbon polyunsaturated fatty acid naturally occurring in certain plant and marine lipid fractions.
It functions as a bioactive lipid ingredient in nutritional, cosmetic, and pharmaceutical formulations where specific fatty acid profiles are required for product efficacy and stability.
In personal care, it is incorporated into skin-conditioning emulsions and barrier-repair formulations where its moisturizing and stabilizing properties support lipid-layer restoration.
Nutritional supplement manufacturers source it as a reference fatty acid or minor active component in omega-profile blends targeting specific dietary compositions and health benefits.
In biotechnology and life sciences, it serves as an analytical reference standard and cell culture media additive for lipid metabolism research and specialized laboratory applications.
Feed formulators use it when developing precision lipid supplements aimed at optimizing fatty acid ratios in animal nutrition programs and high-performance livestock diets.
Eicosatrienoic acid is typically supplied as a neat liquid or dissolved in organic solvent at defined concentrations, with high-purity grades available for research and pharmaceutical use.
Food-grade and technical-grade material can be sourced for formulation development. Packaging is generally offered in small quantities reflecting its positioning as a specialty ingredient.
