  • Applications

    (+-)-7-Hydroxyoctanoic acid (CAS 17173-14-7) is a fatty hydroxy acid that serves as a versatile chemical building block. In practice, it can be used as an intermediate for fragrance ingredient synthesis, as well as a precursor for specialty polyesters and plasticizers. It may also be employed as a precursor for surfactant and emulsifier derivatives in cleaning and cosmetics, and as a processing aid or emollient in personal care formulations. Additionally, it can be a starting material in pharmaceutical or agrochemical synthesis. Use is subject to local regulations and formulation limits.
