Description

Polyethylene Glycol Trimethylnonyl Ether is a nonionic surfactant belonging to the class of alcohol ethoxylates. This compound is valued for its excellent wetting, emulsifying, and dispersing properties, making it a versatile performance additive in numerous industrial formulations. It is particularly sought after by manufacturers in the personal care, agrochemical, textile, and industrial cleaning sectors for its ability to modify surface tension and enhance product stability.

Application

• Personal Care & Cosmetics: Acts as an emulsifier, solubilizer, and mild surfactant in creams, lotions, and hair care products.
• Agrochemical Formulations: Used as a wetting agent, dispersant, and penetrant in pesticide and herbicide concentrates.
• Industrial & Institutional (I&I) Cleaners: Serves as a key surfactant in heavy-duty degreasers, floor cleaners, and detergent blends.
• Textile Processing: Functions as a leveling agent, dye dispersant, and wetting agent in dyeing and finishing operations.
• Paints & Coatings: Employed as a pigment wetting and grinding aid to improve color development and dispersion stability.
• Metalworking Fluids: Used as an emulsifier and lubricity agent in synthetic and semi-synthetic coolants.

Quality Control

Our Polyethylene Glycol Trimethylnonyl Ether is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for critical parameters such as hydroxyl value, ethylene oxide content, and cloud point. Certificates of Analysis (COA) documenting purity, identity, and physical properties 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, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
