Clariant Emulsogen 3971 Ne is a branched alcohol ethoxylate nonionic surfactant designed for agrochemical EW/SE formulations and industrial oil emulsions. Its molecular structure enables ultra-low interfacial tension (≤1 mN/m) while stabilizing high oil-load systems (up to 40%). Compatible with glyphosate, neonicotinoids, and ester oils, it prevents crystallization in concentrated formulations. The APEO-free liquid readily integrates into pesticide pre-mixes and metalworking fluid concentrates under cold processing .
Dual-Functionality – Combines emulsification and dispersion for complex formulations .
Thermal Resilience – Maintains stability in storage from -5°C to 50°C .
Salt Tolerance – Resists electrolyte effects up to 5% NaCl concentration .
Shear Resistance – Withstands high-pressure homogenization (150+ bar) .
Eco-Compliance – OECD 301F biodegradable with ≤0.5% VOC .
Chlorantraniliprole SC – Prevents settling in suspension concentrates .
Metal Rolling Oils – Stabilizes ester-based emulsions for aluminum foil production .
Herbicide Oil Dispersion – Enhables adjuvant compatibility in glyphosate blends .
Textile Spin Finishes – Improves fiber lubricity in polyester processing .
