  • Applications

    Ethyl 4-hydroxyoctanoate is typically used as a functionalized fatty-ester intermediate in fragrance and flavor synthesis and as a cosmetic ingredient due to its emollient properties. The hydroxyl group enables further derivatization, allowing it to be used as a co-monomer or reactive additive in polyurethane and polyester polymer systems. It can also function as a processing aid or plasticizer in specialty coatings and adhesives, and may serve as a solvent in select industrial formulations.
