  • Applications

    2-Methylhenicosane, CAS 1560-82-3, is a long-chain branched alkane with a high boiling point, typically used as a nonpolar hydrocarbon component in formulations. In practical terms, it is employed as: (1) a base oil component in lubricants and industrial oils; (2) a constituent of paraffin waxes and wax-based coatings, candles, and polishes; (3) a processing aid or slip agent in polymer and plastics formulations; (4) a nonpolar emollient or carrier in cosmetics and personal care products; (5) a nonpolar solvent or diluent in industrial manufacturing. Applications are formulation-specific and subject to local regulations and limits.
