Sodium toluenesulfonate

Sodium toluenesulfonate (CAS 12068-03-0), also known as sodium tosylate, is an aromatic sulfonate salt used in formulation and process chemistry as a hydrotrope and solubilizing agent.

Where is Sodium toluenesulfonate used?

• Personal care and household cleaning: hydrotrope
• Shampoos, liquid detergents and body washes: reduces viscosity and improves clarity
• Pharmaceuticals: solubilizer and counterion source
• API salt formation: improves bioavailability and processability
• Agrochemicals: dispersion and wetting in suspension concentrates and emulsifiable concentrates
• Industrial process chemistry: coupling agent and phase modifier in sulfonation and synthesis workflows
• It improves the water solubility of poorly soluble actives and surfactant systems.

Commercial specifications

• Purity typically 98% or higher for most uses
