  • Applications

    11-Hydroxyundecanoic acid is a long-chain hydroxy fatty acid that is primarily used as a bio-based intermediate for polymer synthesis. In industry it is commonly used as a precursor for polyester and polyurethane formation via condensation reactions, and can be converted into specialty esters for surfactants and lubricants. It may also serve as a building block for biodegradable polymers and for cosmetic/personal care formulations, and finds use in coatings, inks, and related formulation applications where its hydroxyl and carboxyl functionalities enable further functionalization and stabilization.
