Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-(Butoxyhydroxyphosphinyl)-.Omega.-Hydroxy-, C13-15-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 after 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 cleaning formulations, and alkaline cleaners.
• Agrochemical Formulations: Used as an emulsifier and dispersant in pesticide and herbicide concentrates (EC, SC formulations) to improve stability and spray application.
• Textile Processing: Employed as a lubricant, antistatic agent, and dyeing assistant to ensure uniform processing and fiber finish.
• Personal Care & Cosmetics: Functions as a mild surfactant and emulsifier in select rinse-off products, leveraging its good skin compatibility.
• Metalworking Fluids: Serves as an emulsifier and corrosion inhibitor in soluble oils and semi-synthetic coolants.
• Paints & Coatings: Acts as a pigment dispersant and grinding aid to improve color development and stability in water-based systems.
• Enhanced Oil Recovery (EOR): Investigated for use as a surfactant to reduce interfacial tension in chemical flooding processes.
