  • Applications

    Chemical name: Octatriacontane. CAS number: 7194-85-6 is a long-chain alkane with a high molecular weight used primarily as a waxy component and oil base in industrial formulations. In cosmetics and personal care, it acts as a waxy thickener and texture modifier in balms, solid perfumes, and lip products. In coatings and inks, it is added as a wax additive to adjust gloss, slip, and water resistance. In polymers and plastics, it serves as a processing aid or slip agent to reduce surface friction during processing. In household products, it appears as a wax component in polishes and candles, contributing gloss and structural stability. In industrial manufacturing, octatriacontane can be used as a high-molecular-weight base oil or lubricant additive for high-temperature applications, and as an additional wax component in lubricant systems, subject to local regulations and formulation limits.
