Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Phenyl-.Omega.-Hydroxy-, Phosphate is a specialized nonionic surfactant and emulsifier, chemically defined as a phosphate ester of a phenyl-terminated polyethylene glycol. This compound is valued for its excellent emulsifying, dispersing, and wetting properties, particularly in challenging formulations. It is a critical ingredient for industrial manufacturers requiring stable emulsions and effective surface activity. Key sectors that utilize this chemical include agrochemicals, coatings, textiles, and personal care products.

Application

• Agrochemical Formulations: Acts as a primary emulsifier and dispersant in pesticide concentrates (EC, SC, EW) and adjuvant systems.
• Coatings & Inks: Provides pigment wetting, grinding aid, and stabilization in water-based and solvent-based systems.
• Textile Processing: Used as a leveling agent, dye dispersant, and scouring aid in fiber treatment.
• Personal Care & Cosmetics: Functions as an emulsifier and solubilizer in creams, lotions, and hair care products.
• Industrial Cleaners: Enhances the wetting and degreasing power of heavy-duty detergent formulations.
• Metalworking Fluids: Serves as an emulsifier and corrosion inhibitor in synthetic and semi-synthetic coolants.
• Polymerization: Can be employed as an emulsifier in emulsion polymerization processes for synthetic rubbers and plastics.
