Description

Sodium n-Tridecylbenzenesulfonate is a high-purity anionic surfactant derived from a linear alkylbenzene sulfonate (LAS) structure. This compound is valued for its excellent wetting, emulsifying, and foaming properties, making it a critical performance additive in demanding industrial formulations. It is essential for manufacturers in sectors requiring robust and reliable surface-active agents, such as agrochemicals, industrial cleaning, and textile processing.

Application

• Agrochemical Formulations: Acts as a key wetting agent and emulsifier in pesticide and herbicide concentrates to improve spray coverage and efficacy.
• Industrial & Institutional (I&I) Cleaners: Used in heavy-duty degreasers, metal cleaners, and floor care products for its powerful detergency and foam stability.
• Textile Processing: Serves as a scouring agent, dye leveling agent, and wetting agent in fiber treatment and dyeing baths.
• Emulsion Polymerization: Functions as an effective surfactant in the production of synthetic rubbers, plastics, and latex paints.
• Oilfield Chemicals: Employed in drilling muds and enhanced oil recovery formulations as an emulsifier and dispersant.
• Leather Processing: Used in soaking, degreasing, and dyeing stages to ensure uniform penetration and processing.
