Description

Polyethylene Glycol Trimethylnonyl Ether is a high-performance 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 ingredient in demanding industrial formulations. It is particularly sought after by manufacturers in the agrochemical, coatings, textile, and personal care industries for creating stable and effective products.

Application

• Agrochemical Formulations: Acts as a key wetting agent, emulsifier, and dispersant in pesticides, herbicides, and fungicides to enhance coverage and efficacy.
• Coatings and Inks: Used as a pigment dispersant and grinding aid to improve color development, stability, and application properties.
• Textile Processing: Serves as a leveling agent, dye dispersant, and scouring aid to ensure uniform dye uptake and fabric quality.
• Industrial & Institutional Cleaners: Functions as a surfactant in heavy-duty degreasers and cleaning concentrates for its robust performance.
• Personal Care & Cosmetics: Employed as an emulsifier and solubilizer in creams, lotions, and hair care products for stable emulsions.
• Metalworking Fluids: Used as a coupling agent and emulsifier in coolants and lubricants to improve stability and performance.

Quality Control

Our Polyethylene Glycol Trimethylnonyl Ether is manufactured under a strict quality management system. Each batch is tested to ensure consistent performance characteristics such as hydroxyl value, cloud point, and viscosity. Certificates of Analysis (COA) documenting these parameters are available upon request to support your quality assurance and regulatory compliance needs.

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