  • Applications

    Ethyl gamma-linolenate (CAS 31450-14-3) is mainly used as a fatty-ester intermediate and specialty additive in chemical synthesis. It serves as a building block for fatty-acid-derived derivatives such as alkyd-resin components for coatings and inks, and can function as a plasticizer or lubricant precursor in polymer formulations. In cosmetics and personal-care products, it is employed as an emollient and carrier for other ingredients. It may also play a role as a solvent or processing aid in cleaning and industrial formulations, with use dependent on regulatory and formulation limits.
