Description

Nonylphenoxypolyoxyethanol CAS NO 51938-25-1 is a nonionic surfactant belonging to the alkylphenol ethoxylate (APE) family, valued for its excellent emulsifying, wetting, and dispersing properties. Its primary commercial value lies in providing stable performance in demanding formulations across various industrial processes. This chemical is essential for manufacturers in sectors such as agrochemicals, textiles, paints and coatings, and industrial cleaning, where effective surface activity is critical.

Application

• Agrochemical Formulations: Acts as a key emulsifier and wetting agent in pesticide and herbicide concentrates, improving spray coverage and efficacy.
• Textile Processing: Used in scouring, dyeing, and finishing baths as a detergent and leveling agent to ensure uniform color and fiber treatment.
• Paints & Coatings: Serves as a dispersant and stabilizer for pigments and fillers, preventing agglomeration and ensuring a smooth, consistent finish.
• Industrial & Institutional (I&I) Cleaning: A core component in heavy-duty degreasers, metal cleaners, and floor strippers due to its strong grease-cutting power.
• Paper & Pulp Industry: Functions as a de-inking agent and dispersant in the recycling process and as a felt washing aid in paper production.
• Metalworking Fluids: Employed as an emulsifier in soluble oils and coolants to provide lubrication and corrosion inhibition during machining operations.
• Leather Processing: Used in soaking, degreasing, and dyeing stages to improve penetration of chemicals and dyes into the hide.
• Oilfield Chemicals: Utilized in drilling mud formulations and as an emulsifier in crude oil demulsification processes.
