The areas of use and the hydrotropic action of sodium cumenesulfonate and potassium/ sodium cumenesulfonate are comparable. The hydrotropic action of cumenesulfonates can be used to improve the homogeneity of liquid detergents. Cumenesulfonates increase the solubility of surfactant products in water and improve the ability of detergent and cleaner formulations to accept electrolytes. The solubility-improving action is accompanied by a decrease of the clear melting point of the formulation. Cumenesulfonates reduce the viscosity of detergent and cleaner formulations. This effect can be used to prepare concentrates with a high surfactant content. Cumenesulfonates can successfully be used to increase the upper cloud points of nonionic surfactant solutions (with or without electrolyte). It has been observed in numerous formulations that increasing the amount of cumenesulfonate can also increase the detergency and cleaning action.

Storage & Handling
- Storage And Handling
- Stainless steel vessels (Steel No.: 1.4541 or 1.4571) at least 25°C.
- Sodium cumene sulphonate 40 is highly compatible with the surfactants, builders and auxiliaries common in detergents and cleaners. The storage temperature should be at least 25 °C. At lower temperatures, the product crystallizes to give white flakes, which can be re-dissolved by warming to 50-60°C. Before removal of product from the container, the contents must be homogenized. Freezing and thawing do not affect the physical, chemical and applicational properties.
- Protect from direct light!
- During storage a precipitation may occur in sodium cumene sulphonate 40 which consists of iron hydroxide and iron oxide hydrate in few ppm- quantities. As a rule the precipitation has no impact on the application properties of sodium cumene sulphonate 40. If necessary the precipitation can be separated off by siphon off the clear upper phase.
