Sodium potassium cumene sulfonate, also known as SPCS, is an anionic surfactant with hydrotropic properties. When dissolved in water, hydrotrope can increase the solubility of sparingly soluble organic substances, lower the cloud point (the temperature above which an aqueous solution of a water-soluble substance becomes cloudy) of aqueous products and reduce the viscosity of aqueous products. Sodium potassium cumene sulfonate has a lower crystallization temperature compared to sodium cumene sulfonate. This characteristic is useful for working at temperatures below +100C.
In the cleaning industry, it is used as an ingredient in cleaning products or as a main component in the removal of waxes, grease deposits and other organic soils. It is also used as an anticoagulant to prevent the aggregation of fine particles into larger aggregates.
In metalworking, sodium potassium cumene sulphonate is used in the cleaning and preparation of metal surfaces as it effectively dissolves grease and prevents the aggregation of fine particles into larger particles and their deposition on the surface.
In water treatment, sodium potassium cumene sulfonate is used to bind hydrogen sulfide (a rotten egg smelling compound). It is commonly used in waste water treatment and in oil drilling.
In cosmetics, sodium potassium cumene sulfonate is used to increase the solubility of compounds in water, thereby improving the removal of impurities from skin and hair. This component is used in the manufacture of make-up removers such as micellar water.
In agriculture, sodium potassium cumene sulfonate is used in the manufacture of various plant protection products where the active ingredients are of fatty origin (e.g. herbicides) and are difficult to mix with water. In this way, sodium potassium cumene sulfonate increases the penetration of the active substances into the plant.
