Description

Triethylene Glycol Mono(p-Nonylphenyl) Ether is a nonionic surfactant belonging to the alkylphenol ethoxylate family, characterized by its hydrophobic nonylphenyl chain and hydrophilic triethylene glycol moiety. This chemical structure provides excellent emulsifying, wetting, and dispersing properties, making it a versatile intermediate and additive. It is primarily utilized in the formulation of industrial cleaners, agrochemicals, textile processing aids, and as an emulsifier in polymerization processes.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a key surfactant and emulsifier in heavy-duty degreasers, metal cleaners, and floor care formulations.
• Agrochemical Formulations: Used as an emulsifier and wetting agent in pesticides, herbicides, and fungicides to improve sprayability and target adhesion.
• Textile Processing: Serves as a dye leveling agent, scouring aid, and wetting agent in various textile manufacturing steps.
• Polymerization & Resins: Functions as an emulsifier in emulsion polymerization processes for synthetic rubbers, plastics, and coatings.
• Metalworking Fluids: Incorporated as an emulsifier and coupling agent in soluble oils and synthetic coolants.
• Leather Processing: Used in fatliquoring and dyeing processes to improve penetration and uniformity.
