  • Applications

    5-Methylhentriacontane (CAS 71502-24-4) is a high-molecular-weight, branched long-chain alkane that functions mainly as a waxy, inert component in formulations. In cosmetics and personal care, it serves as a texture modifier and slip agent in solid products such as lip balms and sticks. In household products, it acts as a paraffin-like wax component in candles, polishes, and surface coatings to improve gloss and durability. In industrial manufacturing, it is used as a nonpolar diluent and lubricant additive in coatings and inks and as a mold-release agent in polymer processing. In polymers and plastics processing, it provides lubrication and helps improve surface finish during extrusion or molding. In cleaning formulations, it can act as a nonpolar carrier or lubricant to aid application of actives. Use is subject to local regulations and formulation limits.
