Sodium 4-methylbenzenesulfonate (CAS: 12068-03-0), commonly sodium tosylate, is the sodium salt of p-toluenesulfonic acid featuring a methyl-substituted aromatic ring and a strongly hydrophilic sulfonate group. This white crystalline compound serves as a hydrotrope and solubilizer in detergent formulations, coupling hydrophobic surfactants and fragrances into clear aqueous solutions at high active concentrations. It functions as an intermediate for surfactant synthesis, a catalyst component in esterification reactions, and as an electrolyte additive in specialty applications. The compound also finds use as a phase-transfer agent and in the preparation of other sulfonate derivatives. Its excellent water solubility, chemical stability, and low cost make sodium tosylate a practical processing aid in cleaning products and chemical manufacturing where sulfonate functionality and solubility enhancement are required.

– Hydrotrope Function: Used to solubilize surfactant blends, fragrances, and hydrophobic additives in concentrated liquid detergent formulations.
– Surfactant Synthesis: Serves as an intermediate for specialty sulfonate surfactants and dispersing agents.
– Esterification Catalysis: Applied as an acid catalyst component in ester formation and condensation reactions for fragrance and plasticizer production.
– Chemical Processing: Employed as a phase-transfer agent and electrolyte in specialty chemical and electrochemical applications.
