Description

Sodium4-(2-Ethylhexyloxycarboxy)Benzenesulfonate is an anionic surfactant and specialty chemical intermediate with a unique molecular structure combining a sulfonate group with a branched alkyl ester chain. This compound is valued for its excellent surface-active properties, including wetting, emulsification, and dispersion capabilities in demanding formulations. It is primarily utilized by manufacturers in the agrochemical, coatings, and specialty detergent industries where high-performance, tailored surfactants are required.

Application

• Agrochemical Formulations: Acts as a key wetting agent, dispersant, and emulsifier in pesticide and herbicide concentrates and soluble liquid (SL) formulations.
• Industrial & Institutional Cleaners: Provides superior detergency and soil suspension in heavy-duty cleaning products for hard surfaces and textiles.
• Coatings & Inks: Used as a pigment grinding aid and dispersant to improve color strength, stability, and application properties in water-based systems.
• Polymerization Aid: Serves as an emulsifier or surfactant in emulsion polymerization processes for synthetic rubbers and plastics.
• Oilfield Chemicals: Employed in drilling muds and production chemicals for its emulsifying and anti-scaling properties.
• Textile Processing: Functions as a leveling agent, dispersant, and wetting agent in dyeing and finishing operations.

Quality Control

Our production of Sodium4-(2-Ethylhexyloxycarboxy)Benzenesulfonate adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analytical testing, including assay, impurity profile, and critical physical property determination. A Certificate of Analysis (COA) documenting all test results is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product quality and handling properties.
