Description

Polyethylene Glycol Monooleyl Ether is a nonionic surfactant derived from oleyl alcohol and ethylene oxide, valued for its excellent emulsifying, dispersing, and wetting properties. This versatile chemical is essential for formulators seeking to stabilize emulsions, reduce surface tension, and improve compatibility between aqueous and oily phases. It finds significant demand across the cosmetics, textile processing, agrochemical, and industrial cleaning sectors.

Application

• Cosmetics & Personal Care: Acts as a primary emulsifier and solubilizer in creams, lotions, and hair care products, providing stable oil-in-water emulsions.
• Textile Processing: Used as a leveling agent, lubricant, and softener in dyeing and finishing operations to ensure uniform color and fabric handle.
• Agrochemical Formulations: Serves as an effective emulsifier and wetting agent in pesticide and herbicide concentrates, enhancing spray coverage and efficacy.
• Industrial & Institutional (I&I) Cleaners: Functions as a key surfactant in heavy-duty degreasers, metal cleaners, and floor care products for superior soil removal.
• Pharmaceuticals: Employed as an excipient in topical ointments and creams for its emulsifying and stabilizing characteristics.
• Paints & Coatings: Aids in pigment dispersion and stabilization in water-based systems, improving product consistency and performance.

Quality Control

Our Polyethylene Glycol Monooleyl Ether is manufactured under a stringent quality management system. Each batch undergoes rigorous testing to ensure consistency in key parameters such as hydroxyl value, saponification value, cloud point, and moisture content. A comprehensive Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support customers requiring compliance with standards such as ISO, GMP, and REACH.

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 product is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent absorption of atmospheric moisture, which can affect product performance.
