Description

Sodium 1,4-Dinonyl Sulphonatosuccinate is a high-purity anionic surfactant belonging to the class of sulfosuccinate esters. This compound is valued for its excellent wetting, emulsifying, and dispersing properties in both aqueous and non-aqueous systems. It is a critical raw material for formulators in the industrial cleaning, agrochemical, and coatings industries seeking reliable performance and supply chain stability.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a powerful wetting agent and emulsifier in heavy-duty degreasers, metal cleaners, and floor care formulations.
• Agrochemical Formulations: Used as a dispersant and emulsifier in pesticide and herbicide concentrates to improve stability and spray application.
• Coatings & Inks: Serves as a pigment dispersant and grinding aid to enhance color development and stability in solvent-based and water-reducible systems.
• Textile Processing: Employed as a wetting and leveling agent in dyeing and finishing baths to ensure uniform color uptake.
• Polymerization: Functions as an emulsifier in the production of synthetic rubbers and certain polymer dispersions (latex).
• Oilfield Chemicals: Utilized in drilling mud formulations and demulsifiers for its surfactant properties.
