Description

Disodium 4-(11-Methyldodecyl) 2-Sulphonatosuccinate is a high-performance anionic surfactant belonging to the class of sulfosuccinate esters. This compound matters for its excellent wetting, emulsifying, and dispersing properties, coupled with good biodegradability and mildness on the skin. It is needed by formulators in the personal care, industrial cleaning, and agrochemical industries seeking effective and environmentally considerate surface-active agents. The product is supplied under strict quality control to ensure batch-to-batch consistency for demanding B2B applications.

Application

• Personal Care & Cosmetics: A key mild surfactant in facial cleansers, shower gels, shampoos, and sensitive skin formulations.
• Industrial & Institutional (I&I) Cleaning: Used in hard surface cleaners, vehicle wash systems, and metal cleaning formulations for superior wetting and soil suspension.
• Agrochemicals: Functions as an effective wetting agent and dispersant in pesticide and herbicide formulations to enhance coverage and efficacy.
• Textile Processing: Employed as a wetting agent and emulsifier in dyeing, scouring, and finishing baths.
• Paints & Coatings: Acts as a pigment dispersant and wetting agent in water-based systems to improve stability and application properties.
• Emulsion Polymerization: Serves as a surfactant in the production of latexes for paints, adhesives, and synthetic rubbers.
