  • Applications

    2-Methyltriacontane (CAS 1560-72-1) is a high-molecular-weight, branched long-chain hydrocarbon. In industry it is typically used as a component of lubricants and greases (as a base oil or viscosity modifier), in paraffin wax formulations and related plastics/copolymer processing aids, and as an inert, nonpolar carrier or diluent in cosmetics, coatings, and specialty cleaning formulations. It may also function as a waxy component in formulation blends for release agents and mold-release applications in plastics processing, and as a nonpolar solvent/diluent in certain industrial cleaners and electronics assembly processes, subject to formulation limits and local regulations.
