Description

Dodecyl Benzenesulphonate is a versatile anionic surfactant and a key intermediate in the production of linear alkylbenzene sulfonates (LAS). This compound is valued for its excellent detergency, foaming properties, and emulsifying power, making it a fundamental building block in numerous industrial formulations. It is essential for manufacturers in the detergent, personal care, and specialty chemical industries seeking high-performance raw materials.

Application

• Primary Detergent Intermediate: The predominant use is as a precursor in the synthesis of linear alkylbenzene sulfonate (LAS), a workhorse surfactant in household and industrial laundry detergents, dishwashing liquids, and all-purpose cleaners.
• Industrial & Institutional (I&I) Cleaners: Serves as a core component in formulations for hard surface cleaners, degreasers, and vehicle wash products due to its powerful grease-cutting and emulsifying action.
• Emulsion Polymerization: Acts as an effective emulsifier and stabilizer in the production of synthetic rubbers (e.g., SBR), plastics, and polymer dispersions like acrylics and styrene-butadiene.
• Textile Processing: Used as a wetting agent, scouring agent, and emulsifier in textile manufacturing for fiber treatment, dyeing, and finishing processes.
• Agricultural Formulations: Employed as a dispersant and emulsifying agent in the production of pesticide and herbicide concentrates and wettable powders.
• Oilfield Chemicals: Functions as a component in drilling mud formulations and enhanced oil recovery (EOR) processes for its surfactant properties.

Quality Control

Our Dodecyl Benzenesulphonate is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. Quality is verified through comprehensive analytical testing including assay, acid value, and color determination. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. The product is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed when not in use to prevent absorption of atmospheric moisture.
