  • Applications

    3-Methylheptacosane (CAS 14167-66-9) is a long-chain branched alkane, primarily used as a paraffinic wax component and processing aid. In industry, it can function as: (1) a component of wax blends for coatings, paints, and inks to adjust viscosity, hardness, and melt behavior; (2) a non-polar lubricant base oil or processing aid in specialty lubricants and plastic/rubber processing; (3) a slip and processing additive in polymer and rubber formulations to improve mold release and reduce friction; (4) an emollient/wax constituent in cosmetics and personal care products, providing slip and texture; (5) a carrier or diluent in fragrance or cosmetic formulations; (6) a non-polar solvent/diluent in cleaning formulations where permitted. Specific applications depend on local regulations and formulation limits.
