Description

Ethanol,2-[2-[2-[2-(4-Nonylphenoxy)Ethoxy]Ethoxy]Ethoxy]-,Hydrogen Sulfate,Sodium Salt is a specialized nonionic-anionic surfactant derived from ethoxylated nonylphenol, functionalized with a sulfate ester group. This unique molecular structure provides excellent wetting, emulsifying, and dispersing properties, making it a critical performance additive in demanding industrial formulations. It is primarily utilized by manufacturers in the agrochemical, textile, and coatings industries where stable emulsions and effective surface activity are required.

Application

• Agrochemical Formulations: Acts as a key emulsifier and wetting agent in pesticide and herbicide concentrates, enhancing spray coverage and active ingredient stability.
• Textile Processing: Used in scouring, dyeing, and finishing baths to improve penetration of chemicals and dyes into fibers.
• Industrial & Institutional Cleaners: Serves as a surfactant in heavy-duty degreasers and cleaning products for its oil-emulsification capabilities.
• Coatings & Inks: Functions as a dispersing and wetting agent in pigment preparations and resin systems to prevent agglomeration.
• Metal Working Fluids: Employed as an emulsifier in soluble oils and synthetic coolants to stabilize oil-in-water emulsions.
• Polymerization: Can be used as an emulsifier in certain emulsion polymerization processes.
