Description

Disodium 4-Decyl 2-Sulphonatosuccinate is a high-performance anionic surfactant belonging to the sulfosuccinate ester class. This compound is valued for its excellent wetting, emulsifying, and dispersing properties, particularly in demanding formulations. It is a critical ingredient for manufacturers in the personal care, industrial cleaning, and agrochemical sectors who require effective surface activity with good skin compatibility and stability across a range of pH levels.

Application

• Personal Care & Cosmetics: Primary surfactant and foaming agent in mild shampoos, body washes, facial cleansers, and bubble baths.
• Industrial & Institutional (I&I) Cleaners: Key wetting and dispersing agent in hard surface cleaners, metal degreasers, and vehicle wash formulations.
• Agrochemicals: Used as an adjuvant in pesticide and herbicide formulations to enhance wetting, spreading, and penetration on plant surfaces.
• Textile Processing: Employed as a wetting agent and emulsifier in dyeing, scouring, and finishing baths.
• Emulsion Polymerization: Serves as a surfactant in the production of acrylic, styrene-butadiene, and other polymer lattices.
• Paints & Coatings: Acts as a pigment dispersant and wetting agent to improve color development and stability in water-based systems.
