Description

4-Tridecylbenzenesulfonic Acid Sodium Salt is a high-purity anionic surfactant and emulsifier, valued for its excellent wetting, dispersing, and detergent properties. This compound is essential for formulating high-performance cleaning agents and industrial processing aids where stability and surface activity are critical. It is primarily used by manufacturers in the detergent, agrochemical, and polymer industries.

Application

• Detergent & Cleaner Formulations: Acts as a key surfactant in industrial and institutional cleaning products, providing superior wetting and grease-cutting power.
• Emulsion Polymerization: Serves as an effective emulsifier and stabilizer in the production of synthetic rubbers, plastics, and latex paints.
• Agrochemical Adjuvants: Used in pesticide and herbicide formulations to enhance the spreading and adhesion of active ingredients on plant surfaces.
• Textile Processing: Functions as a wetting agent and dye dispersant in textile manufacturing and finishing processes.
• Oilfield Chemicals: Employed in drilling muds and oil recovery formulations as an emulsifier and demulsifier.
• Metal Working Fluids: Acts as a corrosion inhibitor and emulsifier in coolants and cutting fluids.

Quality Control

Our 4-Tridecylbenzenesulfonic Acid Sodium Salt is manufactured under a strict quality management system to ensure batch-to-batch consistency and high performance. Each lot is tested against rigorous in-house specifications, which typically include assay, moisture content, and impurity profile analysis. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your technical requirements.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
