Description

Benzenesulfonic Acid, Mono-C11-13-Branched Alkyl Derivs., Sodium Salts is a high-performance anionic surfactant derived from branched-chain alkylbenzenesulfonates, offering excellent detergency, wetting, and emulsifying properties. Its value lies in its superior solubility and stability across a wide pH range compared to linear alkylbenzene sulfonates (LAS), making it a versatile and effective component in demanding formulations. This product is essential for manufacturers in the industrial & institutional cleaning, textile processing, agrochemical, and oilfield chemical industries seeking robust surface-active performance.

Application

• Industrial & Institutional (I&I) Cleaners: A key surfactant in heavy-duty degreasers, floor cleaners, and vehicle wash formulations due to its effective oil and grease removal.
• Textile Processing: Used as a wetting agent, scouring aid, and emulsifier in dyeing and finishing baths to ensure even penetration and processing.
• Agrochemical Formulations: Acts as an effective emulsifier and dispersant in pesticide and herbicide concentrates, enhancing spray coverage and system stability.
• Oilfield Chemicals: Serves as a component in drilling muds and production chemicals for its emulsifying and detergent properties.
• Metal Working Fluids: Employed as an emulsifier and corrosion inhibitor in soluble oils and semi-synthetic coolants.
• Paint & Coating Additives: Functions as a pigment dispersant and wetting agent to improve color development and application properties.
• Leather Processing: Used in soaking, degreasing, and dyeing stages to improve chemical penetration and fatliquoring.
