Description

Benzenesulfonic Acid, Mono- And Di-C15-30-Alkyl Derivs., Sodium Salts is a high molecular weight anionic surfactant derived from the sulfonation of benzene with long-chain C15-30 alkyl groups. This compound is valued for its excellent surface-active properties, including powerful detergency, emulsification, and wetting capabilities, particularly in challenging formulations. It serves as a critical performance additive in industrial cleaning, textile processing, and as a stabilizer or emulsifier in various specialty chemical applications where robust surfactant action is required.

Application

• Industrial & Institutional (I&I) Cleaners: A key component in heavy-duty alkaline and acidic cleaning formulations for degreasing and soil removal.
• Textile Processing: Used as a scouring agent, wetting agent, and emulsifier in dyeing and finishing operations.
• Metal Working Fluids: Acts as an emulsifier and corrosion inhibitor in synthetic and semi-synthetic metalworking coolants.
• Agricultural Formulations: Employed as an emulsifier and dispersant in pesticide and herbicide concentrates.
• Oilfield Chemicals: Functions as a surfactant in drilling muds, emulsifiers for crude oil, and in enhanced oil recovery processes.
• Paint & Coating Additives: Serves as a pigment dispersant and grinding aid to improve color development and stability.
• Leather Processing: Used in beamhouse operations for degreasing and as a wetting agent.
