  • Applications

    Eicosadienoic Acid (CAS 5598-38-9) is primarily used as a feedstock to prepare high-performance esters for lubricants and plasticizers, supporting formulations for metalworking fluids, automotive oils, and polymer blends. It also serves as a building block for surfactants and specialty cleaners, where its long, mid-chain unsaturation helps tailor hydrophobic/hydrophilic balance. In coatings and inks, the acid is a raw material for polyester and alkyd resin derivatization and can function as a plasticizer to modify film properties. In cosmetics and personal care, ester derivatives of Eicosadienoic Acid are explored as emollients or conditioning agents. Additionally, it can be used as a modifying component in adhesive formulations to adjust flexibility and performance. Subject to formulation requirements and regulations.
