Description

Disodium Tridecylsulfosuccinate is a high-performance anionic surfactant belonging to the sulfosuccinate ester class. This compound is valued for its excellent wetting, dispersing, and emulsifying properties, even in challenging electrolyte-rich environments. It is a critical ingredient for formulators in industries such as agrochemicals, coatings, textiles, and personal care, where stable and effective surface activity is required. Its unique branched-chain tridecyl group contributes to superior solubility and performance synergy in complex mixtures.

Application

• Agrochemical Formulations: Acts as a superior wetting agent and dispersant in suspension concentrates (SC), wettable powders (WP), and other pesticide formulations.
• Industrial & Institutional Cleaners: Provides effective emulsification and soil suspension in heavy-duty alkaline and acidic cleaning products.
• Coatings & Inks: Used as a pigment dispersant and grinding aid to improve color development and stability in water-based systems.
• Textile Processing: Functions as a wetting agent and dye leveling assistant in dye baths and pretreatment solutions.
• Personal Care: Employed as a mild secondary surfactant and foam booster in select syndet bars and cleansing products.
• Enhanced Oil Recovery (EOR): Investigated for its potential as a surfactant in chemical flooding due to its tolerance to hard water and high salinity.
• Polymerization: Serves as an emulsifier in the production of certain latex polymers via emulsion polymerization.
