Description

Polyoxy(Methyl-1,2-Ethanediyl), .Alpha.-(Nonylphenyl)-.Omega.-Hydroxy- is a nonionic surfactant belonging to the alkylphenol ethoxylate (APE) family, specifically nonylphenol ethoxylate (NPE). This compound is valued for its excellent surface-active properties, acting as an effective emulsifier, detergent, and wetting agent. It is a critical raw material for formulators in the industrial and institutional cleaning, textile processing, agrochemical, and paint & coatings sectors, where reliable performance and consistent quality are paramount.

Application

• Industrial & Institutional (I&I) Cleaners: A key component in heavy-duty degreasers, floor cleaners, and detergent formulations for its powerful emulsification of oils and greases.
• Textile Processing: Used as a scouring agent, wetting agent, and dye leveling assistant in the pretreatment and dyeing of natural and synthetic fibers.
• Agrochemical Formulations: Serves as an effective emulsifier and dispersant in pesticide and herbicide concentrates (EC, EW, SC formulations) to ensure stable spray applications.
• Paint & Coatings: Acts as a pigment dispersant and grinding aid, improving color development and stability in water-based and solvent-based systems.
• Metal Working Fluids: Functions as an emulsifier in soluble oils and semi-synthetic coolants, providing lubrication and cooling during machining operations.
• Pulp & Paper Industry: Employed in de-inking processes and as a dispersant to improve pulp drainage and paper sheet formation.

Quality Control

Our Nonylphenol Ethoxylate is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure consistency in critical parameters such as ethylene oxide content, hydroxyl value, cloud point, and pH. While primarily supplied as an industrial-grade material, production can be aligned with specific customer requirements. A comprehensive Certificate of Analysis (COA) detailing the specifications for each lot is provided to guarantee traceability and compliance with your formulation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. For long-term storage, blanketing with an inert gas (e.g., nitrogen) is recommended to prevent oxidation and moisture absorption, which can affect product performance.
