  • Applications

    Dodecylbenzene (CAS 123-01-3) is mainly used as an intermediate and feedstock for the production of linear alkylbenzene (LAB), a key precursor for surfactants used in household and industrial detergents. It also serves as a non-polar solvent and processing aid in coatings, inks, and adhesives, facilitating dissolution and blending of hydrocarbon components. In the plastics and polymers sector, it can function as a building block or diluent in manufacturing processes and formulations. Additionally, it may be employed as a solvent in cleaning formulations and industrial equipment cleaners, subject to local regulations and formulation limits.
