Description

1,4-Bis(2-Ethylhexyl) 2-Sulphosuccinate is a high-purity anionic surfactant belonging to the sulfosuccinate ester class. 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 personal care, agrochemical, and industrial cleaning sectors, where performance and consistency are paramount.

Application

• Personal Care & Cosmetics: Acts as a primary or secondary surfactant in shampoos, body washes, and facial cleansers for its mildness and rich foam generation.
• Agrochemical Formulations: Used as a wetting agent, dispersant, and emulsifier in pesticide and herbicide concentrates to improve spray coverage and efficacy.
• Industrial & Institutional (I&I) Cleaners: Employed in hard surface cleaners, degreasers, and metalworking fluids for its superior detergency and stability.
• Textile & Leather Processing: Functions as a wetting and leveling agent in dye baths and finishing applications.
• Paints & Coatings: Serves as a pigment dispersant and grinding aid to improve color development and stability.
• Emulsion Polymerization: Utilized as an emulsifier in the production of synthetic latexes for adhesives and coatings.
