Description

Disodium 2,2'-Oxybis(4-Dodecylbenzene)Sulfonate is a high-purity, synthetic anionic surfactant belonging to the class of alkyl diphenyl ether disulfonates. This compound is valued for its exceptional wetting, emulsifying, and dispersing properties, particularly in challenging aqueous and non-aqueous systems. It is a critical performance additive for formulators in the industrial cleaning, agrochemical, and coatings industries who require robust surfactants with high electrolyte tolerance and thermal stability.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a powerful wetting agent and emulsifier in heavy-duty alkaline and acidic cleaners, degreasers, and metal treatment formulations.
• Agrochemical Formulations: Used as a key component in pesticide and herbicide concentrates to enhance spreading, penetration, and stability of active ingredients.
• Coatings and Inks: Serves as a dispersant and stabilizer for pigments and fillers in water-based and solvent-based systems, improving color development and preventing settling.
• Textile Processing: Employed in scouring, dyeing, and finishing baths for its excellent wetting and leveling properties on synthetic and natural fibers.
• Oilfield Chemicals: Functions as a surfactant in drilling muds, stimulation fluids, and enhanced oil recovery (EOR) applications due to its stability in high-salinity environments.
• Polymerization: Can be utilized as an emulsifier in emulsion polymerization processes for synthetic rubbers and plastics.
