Description

Bis(Tridecyl) Sodium Sulfosuccinate is an anionic surfactant belonging to the dialkyl sulfosuccinate ester class. This compound is valued for its excellent wetting, emulsifying, and dispersing properties in non-polar and low-polarity media. It is primarily sought after by formulators in the industrial, agrochemical, and coatings sectors who require high-performance surfactants that are effective in organic systems and exhibit good hydrolytic stability.

Application

• Primary emulsifier and wetting agent in agricultural chemical formulations (e.g., emulsifiable concentrates).
• Dispersing agent for pigments and fillers in solvent-based paints, inks, and coatings.
• Key ingredient in industrial and institutional cleaning formulations for hard surface cleaners.
• Emulsifier in the production of polymerization emulsions and latex.
• Additive in metalworking fluids and lubricants for improved surface wetting.
• Component in specialty chemical formulations for the textile and leather processing industries.
• Used in the formulation of oilfield chemicals for enhanced oil recovery and demulsification processes.
