Description

Poly(Oxy-1,2-Ethanediyl), α-Phosphono-ω-(Isooctadecyloxy)-, Potassium Salt (Average Eo 3-12 Mol) is a high-performance phosphate ester surfactant and anionic emulsifier. This compound is valued for its excellent wetting, dispersing, and emulsifying properties, particularly in challenging formulations. It is a critical component for industries requiring stable emulsions and effective surface activity in aqueous and non-aqueous systems, with the CAS number 55834-53-2.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a primary emulsifier and wetting agent in heavy-duty degreasers, metal cleaners, and alkaline formulations.
• Agrochemical Formulations: Used as an emulsifier and dispersant in pesticide and herbicide concentrates (EC, SC, EW formulations) to enhance stability and spray performance.
• Textile Processing: Serves as a lubricant, antistatic agent, and emulsifier in fiber spin finishes and textile auxiliaries.
• Metalworking Fluids: Functions as an emulsifier and corrosion inhibitor in soluble oils and semi-synthetic metalworking fluids.
• Paints & Coatings: Employed as a pigment dispersant and grinding aid to improve color development and stability in water-based systems.
• Personal Care: Can be used as a mild surfactant and emulsifier in select rinse-off products, leveraging its potassium salt form.
• Polymerization: Acts as an emulsifier in the emulsion polymerization of styrene, acrylates, and vinyl acetate.
• Oilfield Chemicals: Utilized in drilling muds and completion fluids as an emulsifier and rheology modifier.
