  • Applications

    Dihomo-Gamma-Linolenic Acid (CAS 1783-84-2) finds practical use across several industries as follows: in cosmetics/personal care as an emollient and conditioning lipid; in coatings/inks as a drying oil building block for traditional varnishes and bio-based resins; in industrial manufacturing as an intermediate for lipid-derived esters and specialty chemicals; in pharmaceuticals/nutraceuticals as a component in dietary lipid sources and lipid-based drug delivery formulations; and in polymers/plastics as a potential feedstock for bio-based polymer systems or plasticizers. Use is subject to local regulations and formulation limits.
