Description

Bis[C9-11- Alkylpoly[Oxy-1,2-Ethanediyl)]Phosphate, Monosodium Salt is a high-performance anionic surfactant and emulsifier derived from ethoxylated C9-11 alcohols. This compound matters for its excellent wetting, dispersing, and anti-static properties, making it a critical additive in demanding industrial formulations. It is primarily needed by manufacturers in the textile, agrochemical, and metalworking industries for creating stable emulsions and enhancing process efficiency.

Application

• Textile Processing: Acts as a key wetting agent, lubricant, and anti-static agent in fiber and yarn production.
• Agrochemical Formulations: Serves as an effective emulsifier and dispersant in pesticide and herbicide concentrates.
• Metalworking Fluids: Used as a component in synthetic and semi-synthetic coolants and lubricants for its emulsifying and corrosion-inhibiting properties.
• Industrial Cleaners & Degreasers: Enhances the cleaning power and surface wetting of heavy-duty alkaline and acidic cleaning formulations.
• Paints & Coatings: Functions as a pigment dispersant and grinding aid to improve color development and stability.
• Paper & Pulp Industry: Employed as a debonding agent and dispersant in paper coating and recycling processes.
