Description

Nonylphenol, Ethoxylated, Carboxylated, Sodium Salt is a specialized anionic surfactant derived from the ethoxylation and subsequent carboxylation of nonylphenol. This compound is valued for its excellent emulsifying, wetting, and dispersing properties, particularly in demanding aqueous systems. It is a critical raw material for formulators in industries such as agrochemicals, textiles, and industrial cleaning, where stable performance under various pH and electrolyte conditions is required.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticide concentrates (ECs, SCs) and adjuvant systems.
• Textile Processing: Used in scouring, dyeing, and finishing baths as a wetting agent and detergent.
• Industrial & Institutional (I&I) Cleaners: Serves as a primary surfactant in heavy-duty alkaline and acidic cleaning formulations.
• Metal Working Fluids: Functions as an emulsifier and corrosion inhibitor in synthetic and semi-synthetic coolants.
• Paints & Coatings: Employed as a dispersing agent for pigments and fillers in water-based systems.
• Oilfield Chemicals: Utilized in drilling muds and completion fluids for its surfactant properties.
