  • Applications

    2-Hydroxydecanoic Acid (CAS 5393-81-7) is mainly used as an intermediate in organic synthesis, notably for the production of esters and polyesters that feed into polymers, coatings, and plastics. It is also employed as a precursor for surfactant derivatives and surface-active compounds, supporting cosmetics and personal care products as well as specialty lubricants. In addition, the acid can serve as a building block (diol/diacid) in fat-acid–based polymers such as polyesters or polyurethanes, and is typically used as an intermediate in chemical formulation for coatings, adhesives, and related applications, subject to local regulations and formulation limits.
