SODIUM SULFONATE

Sodium Sulfonate is the sodium salt of sulfonic acids, commonly produced as linear alkylbenzene sulfonates (LAS) or petroleum sulfonates.
Sodium Sulfonate is valued for its excellent surfactant properties, detergency, and ability to disperse oils and particulates.
Sodium Sulfonate is widely used in detergents, lubricants, emulsifiers, corrosion inhibitors, and industrial cleaning agents.
