Description

20-(Dinonylphenoxy)-3,6,9,12,15,18-Hexaoxaicosyl Dihydrogen Phosphate is a high-purity, non-ionic surfactant and specialty phosphate ester. This compound is valued for its excellent emulsifying, wetting, and dispersing properties, making it a critical performance additive in demanding formulations. It is primarily used by manufacturers in the agrochemical, coatings, and lubricant industries seeking to enhance product stability and efficacy.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticide and herbicide concentrates (ECs, SCs) to improve spray coverage and active ingredient stability.
• Industrial Lubricants & Metalworking Fluids: Functions as an effective anti-wear additive and emulsifier, providing lubrication and corrosion inhibition.
• Coatings & Inks: Used as a pigment dispersant and wetting agent to improve color development, gloss, and application properties in solvent-based and water-based systems.
• Polymerization & Resin Production: Serves as an emulsifier and stabilizer in emulsion polymerization processes for plastics and synthetic rubbers.
• Textile Processing: Employed as a leveling agent, dye dispersant, and antistatic agent in fiber treatment and dyeing baths.
• Industrial & Institutional Cleaners: Enhances the degreasing and cleaning power of formulations through its surfactant properties.
