Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.-Hexadecyl-.Omega.-Hydroxy-, Phosphate is a nonionic surfactant and emulsifier belonging to the class of ethoxylated alcohol phosphates. This compound is valued for its excellent emulsifying, dispersing, and wetting properties, making it a critical performance additive in demanding formulations. It is primarily used by manufacturers in the agrochemical, textile, and industrial cleaning sectors who require stable, high-performance surfactant systems.

Application

• Agrochemical Formulations: Acts as a key emulsifier and wetting agent in pesticide and herbicide concentrates, enhancing spray coverage and system stability.
• Textile Processing: Used as a lubricant, antistatic agent, and dyeing assistant to improve fiber handling and color uniformity.
• Industrial & Institutional (I&I) Cleaners: Serves as a primary surfactant in heavy-duty degreasers, metal cleaners, and hard surface cleaners for its robust detergency.
• Emulsion Polymerization: Functions as an effective emulsifier in the production of polymers like acrylics, vinyl acetates, and styrene-butadiene.
• Metalworking Fluids: Incorporated into coolants and drawing compounds for its emulsifying and lubricity properties.
• Personal Care (Rinse-off products): Used in select rinse-off formulations such as shampoos and body washes for its foaming and cleansing characteristics.

Quality Control

Our production of Poly(Oxy-1,2-Ethanediyl), .Alpha.-Hexadecyl-.Omega.-Hydroxy-, Phosphate adheres to a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in key parameters such as active content, pH, and free phosphate levels. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

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). This material is hygroscopic (moisture-sensitive); ensure containers are kept sealed to prevent absorption of atmospheric moisture which may affect product performance.
