  • Applications

    Heptadecylcyclohexane (CAS 19781-73-8) is a long-chain hydrocarbon that is typically treated as a non-polar solvent or diluent in industrial manufacturing and may be used as an intermediate in organic synthesis. It can also serve as a processing aid or lubricant in polymer and plastics processing, supporting handling and surface properties. In coatings and inks, it may be used as an additive to improve flow and slip of the coating layer. Additionally, formulations in cosmetics and household products may consider it as a solvent or carrier for hydrophobic ingredients. Use is subject to local regulations and formulation limits.
