Description

26-(Nonylphenoxy)-3,6,9,12,15,18,21,24-Octaoxahexacosan-1-Yl Hydrogen Phosphate is a specialized nonionic surfactant and phosphate ester, valued for its unique combination of hydrophilic polyether chains and a hydrophobic nonylphenol group. This structure provides excellent emulsifying, wetting, and dispersing properties, making it a critical performance additive in demanding formulations. It is primarily sought by manufacturers in the agrochemical, coatings, textile, and industrial cleaning sectors for developing high-performance products.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticide concentrates (ECs, SCs) and adjuvant systems to enhance spray coverage and active ingredient efficacy.
• Industrial Coatings & Inks: Used as a pigment wetting and grinding aid, improving color development, stability, and flow properties in solvent-based and water-reducible systems.
• Textile Processing: Serves as a leveling agent, lubricant, and antistatic agent in fiber manufacturing and dyeing processes.
• Metalworking Fluids: Functions as an emulsifier and corrosion inhibitor in synthetic and semi-synthetic coolants and lubricants.
• Industrial & Institutional (I&I) Cleaners: Provides powerful emulsification for grease and oil in heavy-duty degreasers and hard surface cleaners.
• Polymerization: Can be employed as an emulsifier or stabilizer in certain emulsion polymerization processes.
