Description

Polyoxyethylene(12) 2,4-Dinonylphenyl Ether Sulfate Sodium Salt is a high-performance anionic-nonionic surfactant, valued for its excellent emulsifying, wetting, and dispersing properties in demanding formulations. Its unique branched-chain structure provides superior stability and compatibility across a wide pH range and in the presence of electrolytes. This versatile surfactant is essential for formulators in the agrochemical, textile, and industrial cleaning sectors seeking robust performance under challenging conditions.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticide and herbicide concentrates (ECs, SCs), enhancing stability and spray performance.
• Textile Processing: Used as a wetting agent, leveling agent, and emulsifier in dyeing, scouring, and finishing baths.
• Industrial & Institutional (I&I) Cleaners: Serves as a primary surfactant in heavy-duty alkaline and acidic cleaners, degreasers, and metal treatment fluids.
• Emulsion Polymerization: Functions as an effective emulsifier and stabilizer in the production of acrylic, vinyl acetate, and styrene-butadiene latexes.
• Oilfield Chemicals: Employed in drilling muds, fracturing fluids, and demulsifiers for its interfacial activity and salt tolerance.
• Leather Processing: Used in soaking, degreasing, and dyeing processes to improve penetration and uniformity.
