Description

α-(4-Hexadecylphenyl)-ω-Hydroxy-Poly(Oxy-1,2-Ethanediyl) is a nonionic surfactant belonging to the alkylphenol ethoxylate family, characterized by its hydrophobic hexadecylphenyl chain and hydrophilic polyoxyethylene tail. This structure provides excellent emulsifying, dispersing, and wetting properties, making it a critical performance additive in numerous industrial formulations. It is primarily utilized by manufacturers in the agrochemical, coatings, textile, and polymer industries where stable emulsions and effective surface activity are required.

Application

• Agrochemical Emulsifier: A key component in pesticide and herbicide formulations for emulsifying active ingredients and improving spray coverage and plant adhesion.
• Industrial & Institutional Cleaners: Used as a surfactant and wetting agent in heavy-duty cleaning products, degreasers, and metalworking fluids.
• Coatings & Inks: Acts as a pigment dispersant and grinding aid to improve color development, stability, and application properties in paints and printing inks.
• Textile Processing Aid: Employed in scouring, dyeing, and finishing operations to enhance wetting, leveling, and fiber lubrication.
• Polymerization Emulsifier: Serves as an emulsifier in emulsion polymerization processes for producing synthetic rubbers, latexes, and acrylic polymers.
• Oilfield Chemicals: Used in drilling muds and production chemicals as an emulsifier and viscosity modifier.

Quality Control

Our α-(4-Hexadecylphenyl)-ω-Hydroxy-Poly(Oxy-1,2-Ethanediyl) is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure consistent performance, including analysis of key parameters such as hydroxyl value, ethylene oxide content, and cloud point. Certificates of Analysis (COA) detailing these specifications are available upon request to support your quality assurance and regulatory compliance 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, sealing under an inert atmosphere such as nitrogen is recommended to prevent oxidation and moisture absorption.
