Description

Sodium Cumenesulfonate is a versatile, water-soluble anionic surfactant and hydrotrope derived from cumene. This compound is valued for its excellent solubilizing and coupling properties, enhancing the stability and clarity of complex aqueous formulations. It is a critical component for manufacturers in the detergent, agrochemical, and personal care industries seeking to improve the performance of their products. Its ability to function effectively across a wide pH range makes it a reliable choice for demanding industrial applications.

Application

• As a hydrotrope and coupling agent in liquid detergents and cleaners to prevent phase separation and increase surfactant solubility.
• In agricultural formulations as a dispersant and stabilizer for pesticides and herbicides.
• As a viscosity modifier and stabilizer in industrial and institutional cleaning products.
• In personal care products like shampoos and liquid soaps for its mildness and clarifying effects.
• As a dye leveling agent and auxiliary in textile processing.
• In oilfield chemicals for formulation of drilling muds and other functional fluids.
• As a processing aid in emulsion polymerization and other chemical synthesis processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can lead to caking or reduced flowability.
