Description

Sodium 3-Tridecylbenzenesulphonate 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 demanding industrial formulations. It is essential for manufacturers in the detergent, agrochemical, and textile processing industries seeking reliable and effective surface-active agents.

Application

• Industrial & Institutional (I&I) Cleaners: A key surfactant in heavy-duty liquid and powder detergents, degreasers, and floor cleaners.
• Agrochemical Formulations: Used as a wetting agent, dispersant, and emulsifier in pesticides, herbicides, and fungicides to enhance coverage and efficacy.
• Textile Processing: Functions as a scouring agent, wetting agent, and dye leveling assistant in various textile manufacturing steps.
• Emulsion Polymerization: Serves as an anionic emulsifier in the production of synthetic rubbers, latexes, and polymer dispersions.
• Oilfield Chemicals: Employed in drilling muds and enhanced oil recovery formulations for its surfactant properties.
• Personal Care: Used in select rinse-off products where its specific surfactant profile is required.
