  • Applications

    Hydroxyundecanoic acid (CAS 6336-28-3) is a bifunctional fatty acid used as a versatile intermediate in the synthesis of esters, polyesters, and polyurethanes, where it can function as a monomer or chain extender to tailor polymer properties. It serves as a precursor for reactive surfactants and specialty ester derivatives that support formulations in cosmetics, personal care, and household cleaners. It can act as a processing aid or plasticizer in polymer and coating systems to improve flexibility and processability. It is also evaluated as a biobased building block for coatings, adhesives, and other industrial chemicals, subject to local regulations.
