Sodium p-cumenesulfonate

Sodium p-cumenesulfonate (CAS 15763-76-5) is an aromatic sulfonate salt used in detergent and industrial cleaning formulations as a hydrotrope.

Where is Sodium p-cumenesulfonate used?

• Household and industrial cleaning: boosts clarity and stability of concentrated liquid detergents and dishwashing liquids
• Hard-surface cleaners: keeps surfactant blends in solution
• Textile and leather processing: dispersing and wetting agent improving dye penetration and chemical uptake
• Agricultural formulations: aids solubilizing active ingredients in emulsifiable concentrate and suspension concentrate systems
• Coatings and adhesives: stabilizes aqueous systems where polar and non-polar components are otherwise difficult to maintain
• It improves the water solubility of poorly soluble actives and allows higher surfactant loading without phase separation.

Good to know: Purity and active content specifications vary by supplier; buyers should confirm concentration and sodium sulfate levels when evaluating grades. Proper storage in a cool, dry environment is recommended.

Commercial specifications

• Aqueous solution, typically 40–45% active content
• Dry powder or granule form for low water content
