  • Applications

    Heptatriacontane (CAS 7194-84-5) is a high‑molecular‑weight n‑alkane that primarily functions as a waxy component in cosmetics and personal care, providing structure and texture in formulations such as creams, lip balms, and stick products. It may also act as a processing aid and slip additive in polymer and plastics formulations, helping processing and surface properties. In coatings and inks, it can serve as a wax additive to improve gloss, water resistance, and mechanical slip. It is encountered in industrial wax blends used for lubrication, release agents, and polishing formulations in household and industrial maintenance products. In pharmaceutical formulations, it may be used as a wax‑based excipient or coating material under appropriate regulatory controls. Use is subject to local regulations and formulation limits.
