Description

Potassium Dodecylbenzenesulphonate is an anionic surfactant belonging to the alkylbenzene sulfonate family. This compound is valued for its excellent emulsifying, dispersing, and wetting properties in aqueous systems. It serves as a critical raw material for formulators in the industrial cleaning, agrochemical, and textile processing sectors, where consistent performance and reliable supply are paramount.

Application

• Primary surfactant and emulsifier in industrial and institutional (I&I) cleaning formulations.
• Wetting and dispersing agent in agricultural chemical products such as pesticides and herbicides.
• Key component in textile processing aids for scouring, dyeing, and finishing operations.
• Emulsifier for polymerization processes, particularly in emulsion polymer synthesis.
• Additive in leather processing chemicals for improved fatliquoring and dye penetration.
• Ingredient in specialty detergent blends for metal cleaning and degreasing.

Quality Control

Our Potassium Dodecylbenzenesulphonate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for active content, purity, and performance characteristics. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee traceability and compliance with 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). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect flow properties and performance.
