  • Applications

    1-Octacosene (CAS 18835-34-2) is a long-chain unsaturated hydrocarbon that can function as a wax-like modifier and processing aid in a range of formulations. In industrial manufacturing, it may be used as a non-polar processing aid and lubricant component for specialty formulations. In polymers and plastics, it is employed as a wax-like additive to adjust melt rheology, slip, and release characteristics in blends and coatings. In coatings and inks, it can improve surface gloss, hardness, and rheology by acting as a waxy additive. In cosmetics and personal care, it may serve as a wax component or texture modifier in niche formulations requiring hydrophobic, low-volatility constituents. In household products, it can be included as a wax or conditioning component in polishes and surface-care formulations, subject to formulation limits and local regulations.
