Description

Isononylphenol-Ethoxylate is a nonionic surfactant belonging to the alkylphenol ethoxylate family, synthesized from isononylphenol and ethylene oxide. This versatile compound is valued for its excellent wetting, emulsifying, and detergent properties, making it a critical performance additive in numerous industrial formulations. It is primarily utilized by manufacturers in the agrochemical, textile, metalworking, and industrial cleaning sectors seeking robust and cost-effective surface-active agents.

Application

• Agrochemical Formulations: Acts as a key emulsifier and wetting agent in pesticide and herbicide concentrates.
• Industrial & Institutional (I&I) Cleaners: Serves as a primary surfactant in heavy-duty degreasers, metal cleaners, and floor care products.
• Textile Processing: Used as a scouring, wetting, and leveling agent in dyeing and finishing operations.
• Metalworking Fluids: Functions as an emulsifier and lubricity agent in soluble oils and coolants.
• Paints & Coatings: Employed as a dispersant and emulsifier to stabilize pigment and resin suspensions.
• Oilfield Chemicals: Utilized in drilling muds and demulsifiers for crude oil processing.
• Leather Processing: Aids in fatliquoring and dyeing processes for uniform application and penetration.
• Paper & Pulp Industry: Acts as a de-inking agent and dispersant in recycling and pulping processes.
