  • Applications

    2-Methyltetracosane (CAS 1560-78-7) is a long-chain branched alkane that is typically used as a non-polar lubricant base oil and processing aid in industrial manufacturing, particularly in high-temperature metalworking fluids and polymer processing. It also appears as a component of synthetic waxes and cosmetic wax formulations to modify texture, slip, and gloss. In coatings and inks, it can act as a non-polar diluent or slip agent to improve flow and surface feel. In cosmetics and personal care, it is used as an emollient and texture-enhancing component in wax-rich formulations. It may also be blended into paraffin-based waxes for candles and household wax products. Its use is formulation-specific and subject to local regulations.
