Description

Siloxanes And Silicones, Di-Me, 3-Hydroxypropyl Me, 3-Hydroxypropyl Group-Terminated, Ethoxylated Propoxylated is a specialized organomodified silicone fluid, distinguished by its reactive hydroxypropyl end groups and hydrophilic ethoxylate/propoxylate side chains. This unique structure provides exceptional surfactant properties, enabling it to act as a powerful wetting agent, emulsifier, and compatibilizer in complex formulations. It is a critical performance additive for manufacturers in the personal care, coatings, textile, and polyurethane foam industries seeking to enhance surface activity, foam stability, and processability.

Application

• Personal Care & Cosmetics: Key surfactant and emulsifier in shampoos, conditioners, and skin creams for improved wetting, spreading, and silky feel.
• Polyurethane Foam Production: Acts as a cell opener and stabilizer in flexible slabstock and molded foam formulations, ensuring uniform cell structure.
• Coatings & Inks: Used as a flow and leveling agent, wetting agent, and defoamer in water-based and solvent-based systems to eliminate surface defects.
• Textile Processing: Employed as a softener, lubricant, and anti-static agent for fibers and fabrics, improving handle and process performance.
• Agricultural Adjuvants: Functions as a super-spreader and activator to enhance the coverage and efficacy of pesticides and herbicides on plant surfaces.
• Industrial Cleaning: Serves as a key component in hard surface cleaners and degreasers for superior wetting and soil penetration.

Quality Control

Our production of this silicone polyether copolymer adheres to strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure consistent performance, including verification of hydroxyl value, ethylene oxide/propylene oxide content, viscosity, and appearance. 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/59-77°F). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
