Description

Sodium p-Cumenesulphonate is the sodium salt of p-isopropylbenzenesulfonic acid, a versatile organic sulfonate compound. It serves as a highly effective hydrotrope, surfactant intermediate, and solubilizing agent, crucial for enhancing the solubility and stability of various formulations. This chemical is essential for manufacturers in the detergent, agrochemical, dye, and personal care industries seeking to improve product performance and process efficiency.

Application

• Hydrotrope and Coupling Agent: Widely used in liquid detergent formulations, including dishwashing liquids and hard surface cleaners, to solubilize surfactants and prevent cloudiness or separation.
• Chemical Intermediate: Serves as a key building block in the synthesis of more complex surfactants and specialty chemicals.
• Dye Dispersant: Acts as a dispersing and leveling agent in textile dyeing processes to ensure uniform color application.
• Agrochemical Formulations: Enhances the solubility and bioavailability of active ingredients in pesticides and herbicides.
• Personal Care Products: Used in shampoos and body washes as a viscosity modifier and clarifier.
• Industrial Cleaning: A component in industrial and institutional (I&I) cleaning products for its degreasing and wetting properties.
• Electroplating Additive: Functions as a brightener and leveling agent in electroplating baths.
• Paper and Pulp Industry: Employed as a dispersant in paper coating and delignification processes.

Quality Control

Our Sodium p-Cumenesulphonate is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, appearance, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and sulfonate content are available upon request to support your quality assurance protocols.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
