Description

Sodium 3-Dodecylbenzenesulfonate is a high-purity anionic surfactant belonging to the linear alkylbenzene sulfonate (LAS) family. This compound is valued for its excellent wetting, emulsifying, and foaming properties in aqueous systems. It is a critical raw material for formulators in the industrial cleaning, agrochemical, and textile processing sectors, where consistent performance and reliable supply are paramount.

Application

• Industrial & Institutional (I&I) Cleaners: A key surfactant in heavy-duty degreasers, floor cleaners, and vehicle wash formulations.
• Agrochemical Adjuvants: Used as a wetting and dispersing agent in pesticide and herbicide formulations to enhance coverage and efficacy.
• Textile Processing: Functions as a scouring agent, wetting agent, and emulsifier in dyeing and finishing processes.
• Emulsion Polymerization: Serves as an anionic emulsifier in the production of synthetic rubbers, plastics, and latex.
• Oilfield Chemicals: Employed in drilling muds and enhanced oil recovery formulations for its surfactant properties.
• Leather Processing: Acts as a wetting and penetrating agent in the tanning and dyeing of leather.
