Description

Poly(Oxy-1,2-Ethanediyl), α-Phosphono-ω-(Isooctadecyloxy)- (Average Eo 3-12 Mol) is a specialized non-ionic surfactant and phosphonate ester, valued for its unique dual functionality as a wetting agent and a scale inhibitor. This compound is engineered to provide excellent surface activity and chelating properties, making it a critical performance additive in demanding industrial formulations. It is primarily sought after by manufacturers in the agrochemical, textile processing, metalworking, and industrial cleaning sectors for its ability to enhance product stability and efficacy.

Application

• Agrochemical Formulations: Acts as a superior wetting agent, dispersant, and penetrant in pesticides, herbicides, and fungicides to improve foliar adhesion and absorption.
• Textile Processing: Used as a scouring agent, dye leveling agent, and antistatic agent to improve fiber wetting and dye uniformity.
• Metalworking Fluids: Functions as an emulsifier and corrosion inhibitor in coolants and cutting oils, providing stability and surface protection.
• Industrial & Institutional (I&I) Cleaners: Serves as a key surfactant and scale inhibitor in acidic and alkaline cleaning formulations for hard surface and equipment cleaning.
• Paints & Coatings: Employed as a pigment dispersant and grinding aid to improve color development and stability in aqueous systems.
• Water Treatment: Utilized as a threshold scale inhibitor for calcium carbonate and sulfate scales in cooling water and boiler water systems.
• Personal Care: Can be used as an emulsifier and mild surfactant in rinse-off products, leveraging its phosphate ester functionality.
