Description

Sodium Decyl Diphenyl Ether Disulfonate is a high-performance anionic surfactant belonging to the diphenyl ether disulfonate chemical family. This compound is valued for its exceptional wetting, emulsifying, and dispersing properties, even in challenging electrolyte-rich and high-temperature environments. It is a critical raw material for formulators in industries such as agrochemicals, enhanced oil recovery, textile processing, and industrial cleaning, where robust performance under harsh conditions is required. The product is supplied as a hygroscopic solid, requiring careful handling and storage to maintain its efficacy.

Application

• Agrochemical Formulations: Acts as a superior wetting agent, dispersant, and emulsifier in pesticides, herbicides, and fungicides, improving spray coverage and system stability.
• Enhanced Oil Recovery (EOR): Used as a key surfactant in chemical flooding to reduce interfacial tension and mobilize residual oil in mature reservoirs.
• Textile Processing: Serves as a leveling agent, dispersant, and wetting agent in dyeing and finishing processes, particularly effective with synthetic fibers.
• Industrial & Institutional (I&I) Cleaning: Provides powerful detergency and emulsification in heavy-duty alkaline cleaners, degreasers, and metal cleaning formulations.
• Polymerization & Emulsion Processes: Functions as an effective emulsifier and stabilizer in the production of synthetic latexes, resins, and other polymer dispersions.
• Personal Care: Used in specialized rinse-off products where high electrolyte tolerance and foam stability are needed.

Quality Control

Our Sodium Decyl Diphenyl Ether Disulfonate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, performance, and compliance with relevant industry standards. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical specifications is provided with every shipment and is available upon request.

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). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance and flow characteristics.
