Description

17-(Nonylphenoxy)-3,6,9,12,15-Pentaoxaheptadecan-1-Yl Dihydrogen Phosphate is a specialized nonionic surfactant and phosphate ester derivative, valued for its unique combination of hydrophilic polyether chains and hydrophobic alkylphenol groups. This structure provides excellent emulsifying, wetting, and dispersing properties, making it a critical performance additive in demanding formulations. It is primarily utilized by manufacturers in the agrochemical, coatings, and industrial cleaning sectors seeking to enhance product stability and efficacy.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticide and herbicide concentrates, improving tank-mix stability and foliar adhesion.
• Industrial Coatings & Inks: Serves as a pigment grinding aid and wetting agent, promoting color development and preventing settling in solvent-based systems.
• Metalworking Fluids: Functions as an emulsifier and corrosion inhibitor in synthetic and semi-synthetic coolants and lubricants.
• Industrial & Institutional (I&I) Cleaning: Used in heavy-duty degreasers and alkaline cleaners for its surfactant and hydrotrope properties.
• Polymerization Aid: Employed as an emulsifier and stabilizer in certain emulsion polymerization processes.
• Textile Processing: Assists in dye leveling and as a scouring agent in fiber treatment baths.
