Description

26-(Nonylphenoxy)-3,6,9,12,15,18,21,24-Octaoxahexacosan-1-Ol is a high-purity, non-ionic surfactant belonging to the class of polyethoxylated nonylphenol derivatives. This compound is valued for its excellent emulsifying, wetting, and dispersing properties in complex formulations. It is a critical raw material for manufacturers in the agrochemical, coatings, textile, and industrial cleaning sectors seeking reliable performance and supply chain consistency.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticide and herbicide concentrates (ECs, SCs).
• Industrial & Institutional Cleaners: Provides superior wetting and degreasing power in heavy-duty detergent formulations.
• Coatings & Inks: Used as a pigment dispersant and grinding aid to improve color development and stability.
• Textile Processing: Functions as a leveling agent, scouring aid, and dye dispersant in fiber treatment baths.
• Metalworking Fluids: Serves as an emulsifier and corrosion inhibitor in soluble oils and coolants.
• Polymerization: Employed as an emulsifier and stabilizer in emulsion polymerization processes for synthetic rubbers and plastics.
• Oilfield Chemicals: Utilized in drilling muds and production chemicals for its surfactant properties.
