Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-[[(2-Ethylhexyl)Oxy]Hydroxyphosphinyl]-.Omega.-Hydroxy-, C9-11-Alkyl Ethers, Sodium Salts is a specialized anionic surfactant belonging to the phosphate ester class, known for its excellent emulsifying, wetting, and dispersing properties. This compound is valued for its stability across a wide pH range and its compatibility with various electrolyte systems, making it a versatile performance additive. It is primarily sought by formulators in the industrial cleaning, agrochemical, textile processing, and personal care industries for creating stable emulsions and enhancing surface activity.

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 improve stability and spray performance.
• Textile Processing: Employed as a lubricant, antistatic agent, and dye leveling assistant in fiber spin finishes and dye baths.
• Personal Care & Cosmetics: Functions as a mild surfactant and emulsifier in select rinse-off products and pigment dispersions.
• Metalworking Fluids: Serves as an emulsifier and corrosion inhibitor in synthetic and semi-synthetic coolants and drawing compounds.
• Paints & Coatings: Utilized as a pigment dispersant and grinding aid to improve color development and stability in water-based systems.
• Pulp & Paper: Applied as a debonding agent and dispersant in paper coating and recycling processes.
