Description

Disodium 4-Dodecyl 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 seeking mild yet effective surface-active agents.

Application

• Personal Care & Cosmetics: A primary surfactant in mild cleansing products such as facial washes, shower gels, and baby shampoos due to its low irritation profile.
• Industrial & Institutional (I&I) Cleaners: Used in hard surface cleaners, degreasers, and vehicle wash formulations for its superior wetting and grease-cutting ability.
• Agrochemical Formulations: Acts as a wetting agent, dispersant, and penetrant in pesticide and herbicide concentrates and spray solutions.
• Textile Processing: Employed as a wetting and leveling agent in dyeing and finishing baths to ensure uniform color application.
• Emulsion Polymerization: Serves as an effective emulsifier in the production of synthetic latexes for paints, coatings, and adhesives.
• Paper & Pulp Industry: Functions as a de-inking agent and dispersant in the recycling and pulping processes.
