Description

Siloxanes and silicones, di-Me, 3-(2-hydroxyphenyl)propyl Me, 3-hydroxypropyl Me, ethers with ethylene oxide-ethyloxirane polymer and polyethylene-polypropylene glycol is a specialized, multi-functional silicone polyether copolymer designed to deliver unique surface-active properties. This compound matters for its ability to act as a highly effective surfactant, wetting agent, and compatibilizer in complex formulations, bridging the performance gap between silicones and organic polymers. It is primarily needed by manufacturers in the personal care, coatings, and polyurethane foam industries seeking advanced performance modifiers.

Application

• Personal Care & Cosmetics: Acts as a premium emulsifier, emollient, and conditioning agent in skin creams, lotions, sunscreens, and hair care products, providing a smooth, non-greasy feel and enhanced spreadability.
• Polyurethane Foam Production: Serves as a key cell opener and stabilizer in flexible slabstock and molded foam formulations, ensuring uniform cell structure and optimal physical properties.
• Coatings & Inks: Functions as a powerful wetting and leveling agent, improving substrate coverage, flow, and slip in water-based and solvent-based coating systems.
• Adhesives & Sealants: Used as a compatibilizer and rheology modifier to enhance adhesion, reduce surface tension, and improve the mechanical properties of silicone-modified polymers.
• Textile & Fiber Treatment: Imparts softness, lubricity, and water repellency as a finishing agent for synthetic and natural fibers.
• Agricultural Adjuvants: Enhances the spreading, sticking, and penetration of agrochemicals on plant surfaces.
• Industrial Cleaners: Improves wetting and surface contact in detergent and cleaner formulations for more effective soil removal.
• Plastics & Polymer Additive: Acts as an internal lubricant and processing aid to improve mold release and surface quality of engineered plastics.

Quality Control

Our silicone polyether copolymers are manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance and meets precise specifications for critical parameters such as viscosity, hydroxyl value, ethylene oxide/propylene oxide ratio, and silicone content. Certificates of Analysis (COA) documenting these results 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/59-77°F). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which may affect product performance.
