Description

Poly(Oxy-1,2-Ethanediyl), α-Phosphono-ω-(Dodecyloxy)-, Compd. With 2,2′-Iminobis[Ethanol], (Eo 2-8 Mol) is a specialized non-ionic surfactant and phosphonate ester derivative, valued for its unique combination of wetting, dispersing, and chelating properties. This compound is engineered to address challenges in formulations requiring high stability and performance under demanding conditions. It is a critical additive for industries focused on advanced material processing and high-performance cleaning, where control over surface interactions and scale inhibition is paramount.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a powerful wetting agent and scale inhibitor in alkaline and acidic detergent formulations for hard surface cleaning.
• Textile Processing: Used as a dye dispersant and leveling agent, and as a stabilizer in peroxide bleaching baths to enhance fabric quality and process efficiency.
• Paints & Coatings: Serves as a pigment dispersant and grinding aid, improving color development, stability, and gloss in water-based and solvent-based systems.
• Metal Treatment & Working Fluids: Functions as a corrosion inhibitor and lubricity agent in metalworking fluids, coolants, and surface treatment baths.
• Pulp & Paper Manufacturing: Employed as a dispersant for fillers and pigments like calcium carbonate and kaolin, and as a process aid to prevent scale deposition.
• Agricultural Formulations: Enhances the stability and efficacy of pesticide and herbicide concentrates by improving emulsification and tank-mix compatibility.
• Personal Care & Cosmetics: Can be utilized in specialized rinse-off products as a mild surfactant and chelant, helping to stabilize formulations.
• Water Treatment: Acts as a threshold inhibitor to control scale formation (e.g., calcium carbonate, calcium sulfate) in cooling water and boiler water systems.
