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.

It improves the solubility and stability of surfactant systems, allowing formulators to build higher-active, clear liquid products without phase separation in various industrial environments.

In household and industrial cleaners, sodium cumene sulfonate enables the formulation of concentrated, water-clear detergents by keeping surfactant blends homogeneous at elevated active levels.

Textile and leather processing operations use it to improve dye bath stability and ensure even distribution of processing agents across fiber substrates during the manufacturing cycle.

In coatings and adhesive systems, it functions as a dispersing aid that helps maintain emulsion stability during manufacture and storage, preventing unwanted sedimentation or separation.

Personal care formulators incorporate it into liquid soaps and shampoos as a viscosity modifier and solubilizer for fragrance and active ingredients to ensure product clarity and performance.

Sodium isopropylbenzenesulfonate is supplied as an aqueous solution, typically at 40% active concentration, and as a dry powder or granule form for applications requiring low moisture content.

Standard supply grades include technical and industrial-grade specifications. Food-contact and cosmetic-grade documentation is available from select suppliers to support regulatory compliance.
