Description

Benzenesulfonic Acid, Dodecyl-, Branched is a versatile organic acid surfactant belonging to the alkylbenzene sulfonate family. Its branched dodecyl chain structure provides excellent detergency, wetting, and emulsifying properties, making it a critical intermediate and functional additive in numerous industrial processes. This compound is essential for manufacturers in the chemical synthesis, agrochemical, and cleaning product industries seeking high-performance anionic surfactants.

Application

• Primary raw material for the synthesis of linear alkylbenzene sulfonate (LAS) surfactants.
• Key intermediate in the production of industrial and institutional (I&I) cleaning formulations and detergents.
• Emulsifier and wetting agent in agrochemical formulations such as herbicides and pesticides.
• Additive in textile processing aids for scouring, dyeing, and finishing operations.
• Component in emulsion polymerization processes for plastics and synthetic rubber.
• Acid catalyst and surfactant in specialized organic synthesis and chemical reactions.
• Ingredient in metalworking fluids and industrial lubricants for its surface-active properties.
