Sodium p-cumenesulfonate

Sodium p-cumenesulfonate (CAS 15763-76-5) is an aromatic sulfonate salt used across detergent and industrial cleaning formulations as a hydrotrope. This compound improves the water solubility of poorly soluble actives and allows formulators to increase surfactant loading without phase separation.

It enables stable, high-concentration liquid formulations that would otherwise require additional solvents or emulsifiers. In household and industrial cleaning products, it boosts the clarity and stability of concentrated liquid detergents and dishwashing liquids.

By keeping surfactant blends in solution, it ensures hard-surface cleaners remain effective. Textile and leather processors use it as a dispersing and wetting agent to improve dye penetration and chemical uptake during various stages of wet processing.

In agricultural formulations, it aids in solubilizing active ingredients within emulsifiable concentrate and suspension concentrate systems. This versatility makes it a staple for manufacturers dealing with complex chemical mixtures and solubility challenges.

Coatings and adhesive manufacturers incorporate it to stabilize aqueous systems where compatibility between polar and non-polar components is otherwise difficult to maintain. It helps prevent sedimentation and ensures a uniform application of the final product.

The material is supplied as an aqueous solution, typically at 40–45% active content, and in dry powder or granule form for applications requiring low water content. Technical grade is the standard offering for most industrial and cleaning applications.

Purity and active content specifications vary by supplier, so buyers should confirm concentration and sodium sulfate levels when evaluating grades. Proper storage in a cool, dry environment is recommended to maintain the stability of the chemical over time.
