Dodecylbenzene (hard type) is primarily used as a key intermediate in the production of linear alkylbenzene sulfonates (LAS), which are widely utilized as surfactants in the manufacturing of household and industrial detergents. Its structure allows for effective cleaning properties, making it essential in formulations for laundry detergents, dishwashing liquids, and other cleaning products. Additionally, it serves as a raw material in the synthesis of lubricants and additives, enhancing the performance of industrial oils. Its stability and compatibility with various chemical processes make it a valuable component in the chemical industry.
