Description

Polyethylene Glycol Trimethylnonyl Ether is a high-purity, non-ionic surfactant belonging to the alkylphenol ethoxylate family, distinguished by its branched nonyl chain. This compound is valued for its excellent wetting, emulsifying, and dispersing properties in a wide range of formulations. It serves as a critical performance additive in industrial cleaning, agrochemicals, textiles, and personal care products, where stability and compatibility are paramount.

Application

• Industrial & Institutional (I&I) Cleaners: Acts as a key surfactant and wetting agent in heavy-duty degreasers, floor cleaners, and metalworking fluids.
• Agrochemical Formulations: Used as an emulsifier and dispersant in pesticides, herbicides, and fungicides to enhance spray coverage and active ingredient stability.
• Textile Processing: Functions as a leveling agent, dye dispersant, and scouring aid in dyeing and finishing operations.
• Personal Care & Cosmetics: Employed as an emulsifier and solubilizer in creams, lotions, and hair care products, though specific grade compliance must be verified.
• Paints & Coatings: Serves as a pigment wetting and grinding aid to improve color development and dispersion stability.
• Pulp & Paper Industry: Utilized as a defoamer component and dispersant in pulp processing and paper coating formulations.

Quality Control

Our Polyethylene Glycol Trimethylnonyl Ether is manufactured under a stringent quality management system. Each batch is tested to ensure consistent performance characteristics such as hydroxyl value, cloud point, and ethylene oxide distribution. A Certificate of Analysis (COA) detailing purity, physical properties, and conformance to agreed specifications is provided with every shipment to guarantee supply reliability and product consistency for your critical processes.

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); keep containers tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product performance.
