Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Phosphono-.Omega.-(Decyloxy)- is a specialized nonionic surfactant and phosphonate-functionalized polyether. This unique molecular structure, combining a polyethylene glycol chain with a terminal phosphonic acid group and a decyl chain, provides excellent surface activity, chelation, and dispersion properties. It is a critical performance additive for formulators in industries such as agrochemicals, coatings, and detergents, where it enhances stability, compatibility, and efficacy. The compound is valued for its ability to act as a wetting agent, dispersant, and scale inhibitor in complex aqueous and non-aqueous systems.

Application

• Agrochemical Formulations: Acts as a superior wetting agent, dispersant, and compatibility agent for pesticides, herbicides, and fungicides, improving spray coverage and tank-mix stability.
• Industrial & Institutional (I&I) Cleaning: Used in heavy-duty detergents and scale removal formulations where its phosphonate group provides chelation of hard water ions (e.g., Ca²⁺, Mg²⁺).
• Coatings & Inks: Serves as a pigment dispersant and grinding aid in water-based paints and inks, enhancing color development and preventing settling.
• Textile Processing: Functions as a leveling agent, detergent, and anti-precipitant in dyeing and scouring baths.
• Water Treatment: Employed as a threshold scale inhibitor and dispersant for calcium carbonate and other mineral scales in cooling and boiler water systems.
• Personal Care: Can be utilized in select rinse-off products as a mild surfactant and conditioning agent, leveraging its emulsifying properties.
• Metal Working Fluids: Enhances the stability of emulsions and provides corrosion inhibition in synthetic and semi-synthetic cutting and grinding fluids.
• Oilfield Chemicals: Applied in drilling muds and production chemicals as a rheology modifier and scale control additive.
