Description

Nonylphenoxy Polyethoxyethanol is a nonionic surfactant belonging to the alkylphenol ethoxylate family. This versatile chemical is valued for its excellent emulsifying, wetting, and dispersing properties in a wide range of industrial formulations. It serves as a critical component for manufacturers in sectors such as agrochemicals, textiles, paints, and industrial cleaning. Its performance is driven by a balanced hydrophilic-lipophilic structure derived from its polyethoxy chain.

Application

• Agrochemical Formulations: Acts as a key emulsifier and wetting agent in pesticide and herbicide concentrates.
• Industrial & Institutional (I&I) Cleaners: Used in heavy-duty degreasers, metal cleaners, and floor care products for its detergency.
• Textile Processing: Functions as a scouring, leveling, and dyeing assistant in fiber treatment baths.
• Paints & Coatings: Serves as a pigment dispersant and grinding aid to improve color stability and application properties.
• Metalworking Fluids: Employed as an emulsifier and lubricity agent in soluble oils and coolants.
• Paper & Pulp Industry: Used in de-inking processes and as a dispersant for coatings.
• Oilfield Chemicals: Applied in drilling muds and emulsion breakers for its surfactant properties.
• Industrial Emulsion Polymerization: Functions as a stabilizer and emulsifier in the production of various polymer lattices.

Quality Control

Our Nonylphenoxy Polyethoxyethanol is produced under a stringent quality management system. Each batch is tested against key parameters to ensure consistent performance and specification compliance. While specific grades may vary in ethoxylation number and physical form, our standard quality commitment includes verification of hydroxyl value, cloud point, pH, and moisture content. Certificates of Analysis (COA) documenting these results are available upon request for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Keep away from strong oxidizing agents. For long-term storage, consider using under an inert atmosphere to prevent oxidation and moisture absorption.
