Description

Nonoxynol-4 is a nonionic surfactant belonging to the alkylphenol ethoxylate family, specifically a 4-mole ethoxylate of nonylphenol. This compound is valued for its effective wetting, emulsifying, and detergent properties in various industrial formulations. It is primarily utilized by manufacturers in the agrochemical, textile, and industrial cleaning sectors where a low-foaming, cost-effective surfactant is required.

Application

• Agrochemical Adjuvants: Used as a wetting agent, emulsifier, and dispersant in pesticide and herbicide formulations.
• Textile Processing: Functions as a scouring, wetting, and leveling agent in dyeing and finishing operations.
• Industrial & Institutional (I&I) Cleaners: A key component in low-foaming detergents and degreasers for hard surface cleaning.
• Emulsion Polymerization: Acts as an emulsifier and stabilizer in the production of synthetic latexes and polymers.
• Metal Working Fluids: Employed as an emulsifier and corrosion inhibitor in cutting oils and coolants.
• Pulp & Paper Industry: Serves as a de-inking agent and dispersant in paper recycling and processing.
