Sodium isopropylbenzenesulfonate

Sodium isopropylbenzenesulfonate (CAS 28348-53-0), commercially known as sodium cumene sulfonate, is an aromatic sulfonate salt used primarily as a hydrotrope and coupling agent in liquid formulations.

Where is Sodium isopropylbenzenesulfonate used?

• Household and industrial cleaners: enables concentrated, water-clear detergents by keeping surfactant blends homogeneous at elevated active levels
• Textile and leather processing: improves dye bath stability and even distribution of processing agents on fiber substrates
• Coatings and adhesives: dispersing aid that maintains emulsion stability during manufacture and storage
• Personal care: viscosity modifier and solubilizer for fragrance and active ingredients in liquid soaps and shampoos
• It improves the solubility and stability of surfactant systems, allowing higher-active, clear liquid products without phase separation.

Commercial specifications

• Aqueous solution, typically 40% active concentration
• Dry powder or granule form for low moisture content
