Description

Polyoxyethylene p-phenylphenyl ether, also known as α-[1,1'-biphenyl]yl-ω-hydroxy-poly(oxy-2-ethanediyl), is a nonionic surfactant belonging to the class of polyoxyethylene alkylaryl ethers. This compound is valued for its excellent emulsifying, dispersing, and wetting properties in demanding industrial formulations. It is a critical component for manufacturers in sectors requiring high-performance surface-active agents, such as agrochemicals, industrial cleaning, and textile processing.

Application

• Agrochemical Formulations: Acts as a key emulsifier and dispersant in pesticides, herbicides, and fungicides, enhancing stability and sprayability.
• Industrial & Institutional (I&I) Cleaners: Provides superior wetting and soil suspension in heavy-duty degreasers and detergent formulations.
• Textile Processing: Used as a scouring, leveling, and dyeing assistant to improve fiber wetting and dye penetration.
• Metal Working Fluids: Functions as an emulsifier in cutting oils and coolants, providing lubrication and rust prevention.
• Paint & Coating Additives: Aids in pigment dispersion and stabilization in water-based and solvent-based systems.
• Polymerization: Serves as an emulsifier and stabilizer in emulsion polymerization processes for synthetic rubbers and plastics.

Quality Control

Every batch of our polyoxyethylene p-phenylphenyl ether is manufactured under a strict quality management system. We ensure product consistency and performance through rigorous in-process and final testing, including analysis of key parameters like hydroxyl value, ethylene oxide content, and cloud point. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and conformance to agreed specifications is provided with each shipment to guarantee supply chain integrity for your production.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
