Description

Siloxanes And Silicones, Di-Me, 3-Hydroxypropyl Group-Terminated, Ethers With Polyethylene-Polypropylene Glycol Mono-Me Ether is a specialized organomodified silicone surfactant, engineered to provide superior surface activity and compatibility in complex formulations. This compound is valued for its ability to act as a highly effective wetting agent, emulsifier, and foam control additive, bridging the performance gap between traditional silicones and organic polyethers. It is essential for formulators in the personal care, coatings, and polyurethane foam industries seeking to enhance product performance, stability, and processability.

Application

• Personal Care & Cosmetics: Acts as a key surfactant and emulsifier in shampoos, conditioners, and skin creams, providing enhanced spreadability, soft feel, and moisture retention.
• Polyurethane Foam Production: Serves as a critical cell stabilizer and surfactant in flexible and rigid foam formulations, ensuring uniform cell structure and optimal physical properties.
• Coatings & Inks: Functions as a flow and leveling agent, wetting agent, and defoamer in water-based and solvent-based systems, improving substrate wetting and final film appearance.
• Agricultural Adjuvants: Used as a spray additive to improve the wetting, spreading, and adherence of pesticides and fertilizers on plant surfaces.
• Industrial Cleaners & Detergents: Enhances the cleaning efficacy and foam profile in industrial and institutional cleaning formulations.
• Textile & Fiber Processing: Employed as a softener, lubricant, and anti-static agent to improve the handle and processing of synthetic and natural fibers.

Quality Control

Our production of this organosilicone surfactant adheres to stringent quality management systems. Each batch is characterized and tested against critical parameters to ensure consistent performance and batch-to-batch reproducibility. While specifications vary by application grade, we guarantee compliance with relevant industry standards. A comprehensive Certificate of Analysis (COA) detailing assay, viscosity, hydroxyl value, and cloud point is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). This product is hygroscopic (moisture-sensitive). Keep container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product performance.
