Description

Butanedioic Acid, Sulfo-, 1-(2-Propenyl) 4-Tridecylester, Sodium Salt is a specialized anionic surfactant and emulsifier derived from a sulfosuccinate ester. This compound is valued for its excellent wetting, dispersing, and emulsifying properties in demanding formulations. It is primarily utilized by manufacturers in the coatings, inks, and agrochemical industries where stable, high-performance surface activity is required.

Application

• As a primary emulsifier in the production of acrylic and vinyl acetate-based polymer emulsions.
• As a wetting and dispersing agent in pigment concentrates and colorants for paints and inks.
• As a stabilizing agent in agricultural chemical formulations, including suspensions (SC) and emulsifiable concentrates (EC).
• In the formulation of industrial and institutional cleaners for enhanced surface wetting.
• As a co-emulsifier in personal care products requiring mild anionic surfactants.
• In the textile industry as an aid in dyeing and finishing processes.
