  • Applications

    Tetradecyloctadecanoic acid (CAS 73756-39-5) is a long-chain fatty acid that can serve as a feedstock for the synthesis of esters and surface-active compounds, enabling surfactants and cleaning formulations; it also functions as an intermediate in the production of additives for plastics, rubber, and coatings; it may be used as a base material for industrial lubricants and lubricant blends; in polymer and coating applications it can act as a wax-like modifier or be converted into esters for coatings and inks; and it can be converted to ester derivatives for cosmetic and personal care formulations.
