Description

Poly(Oxy-1,2-Ethanediyl), α-Phosphono-ω-(Tridecyloxy)-, Branched (Average Eo 3-12 Mol) is a specialized nonionic surfactant and phosphonate ester, valued for its unique combination of wetting, emulsifying, and scale inhibition properties. This compound is engineered to deliver high performance in demanding formulations where stability and surface activity are critical. It is essential for manufacturers in the agrochemical, textile, metalworking, and industrial cleaning sectors seeking advanced additive solutions.

Application

• Agrochemical Formulations: Acts as a key wetting agent, dispersant, and emulsifier in pesticide and herbicide concentrates.
• Textile Processing: Used as a leveling agent, lubricant, and antistatic agent in fiber production and dyeing processes.
• Metalworking Fluids: Functions as an emulsifier and corrosion inhibitor in synthetic and semi-synthetic coolants and lubricants.
• Industrial & Institutional (I&I) Cleaners: Provides superior wetting and soil suspension in heavy-duty alkaline and acid cleaners.
• Paint & Coating Additives: Enhances pigment dispersion and stabilizes emulsion systems in water-based coatings.
• Oilfield Chemicals: Serves as a component in scale inhibitor formulations for water treatment in production and injection systems.
• Personal Care: Used as a mild surfactant and emulsifying agent in select rinse-off products.
