Description

Poly(Oxy-1,2-Ethanediyl), α-Phosphono-ω-((9Z)-9-Octadecenyloxy)-, Compd. With 2,2′-Iminobis(Ethanol) (Eo 2-35 Mol) is a specialized non-ionic surfactant and emulsifier, chemically characterized as an oleyl alcohol ethoxylate phosphate ester neutralized with diethanolamine. This compound is engineered to deliver superior wetting, emulsification, and antistatic properties in complex formulations. It is a critical performance additive for industries requiring stable oil-in-water emulsions and effective surface activity, particularly in textile processing, agrochemicals, and industrial cleaning applications.

Application

• Textile Processing: Acts as a key lubricant, antistatic agent, and emulsifier in fiber spin finishes and textile auxiliaries.
• Agrochemical Formulations: Serves as a primary emulsifier and wetting agent in pesticide and herbicide concentrates (EC, EW).
• Industrial & Institutional (I&I) Cleaning: Used in heavy-duty degreasers and metal cleaning formulations for its excellent emulsifying power on oils and fats.
• Metalworking Fluids: Functions as an emulsifier and corrosion inhibitor in soluble oils and semi-synthetic coolants.
• Leather Processing: Employed as a fatliquoring agent and emulsifier in leather tanning and finishing.
• Paints & Coatings: Aids in pigment wetting and dispersion in water-based coating systems.
• Personal Care: Can be utilized as a mild surfactant and emulsifier in select rinse-off products, depending on the specific ethoxylation degree and purity.
