Description

Sodium Dodecyl Diphenyl Ether Disulfonate is a high-performance anionic surfactant belonging to the diphenyl ether disulfonate chemical class. This compound is valued for its excellent wetting, emulsifying, and dispersing properties, particularly in challenging aqueous systems. It is a critical raw material for formulators in the industrial cleaning, agrochemical, textile, and coatings industries who require robust and stable surfactant performance.

Application

• Primary emulsifier and dispersant in the formulation of agricultural chemicals (herbicides, pesticides, and fungicides).
• Key component in industrial and institutional (I&I) cleaners and degreasers for hard surface cleaning.
• Stabilizing agent and wetting aid in textile processing and dyeing applications.
• Emulsifier for polymerization processes, particularly in emulsion and suspension polymerization.
• Dispersant and grinding aid in the production of pigments, dyes, and ceramic coatings.
• Additive in oilfield chemicals for enhanced oil recovery and drilling mud formulations.
• Foam control agent and detergent builder in specialized cleaning formulations.
