Description

Sodium 1,4-Diisotridecyl Sulphonatosuccinate is a high-performance anionic surfactant belonging to the class of sulfosuccinate esters. This compound is valued for its excellent wetting, emulsifying, and dispersing properties, particularly in systems requiring stability and low surface tension. It is a critical ingredient for formulators in the industrial cleaning, agrochemical, and coatings industries, where its branched-chain structure provides superior performance in challenging formulations.

Application

The versatile surfactant properties of Sodium 1,4-Diisotridecyl Sulphonatosuccinate make it suitable for a wide range of industrial applications:

• Industrial & Institutional (I&I) Cleaners: Acts as a powerful wetting agent and emulsifier in heavy-duty degreasers, metal cleaners, and alkaline cleaning formulations.
• Agrochemical Formulations: Used as a key component in pesticide and herbicide concentrates to enhance spreading, adhesion, and penetration on plant surfaces.
• Coatings & Inks: Serves as an effective dispersant and stabilizer for pigments and fillers in water-based paints, coatings, and printing inks.
• Textile Processing: Employed in scouring, dyeing, and finishing baths to improve wetting and leveling, ensuring uniform color application.
• Oilfield Chemicals: Functions as an emulsifier and surfactant in drilling muds and other oilfield fluid formulations.
• Personal Care (Industrial Grade): Can be used in the manufacture of specific industrial-grade cosmetic and toiletry products requiring robust emulsification.
