Description

Siloxanes and Silicones, di-Me, 3-hydroxypropyl Me, ethers with polyethylene glycol mono-Me ether, polyethylene-polypropylene glycol and polyethylene-polypropylene glycol mono-Me ether is a specialized organomodified silicone surfactant designed to provide superior surface activity and compatibility in complex formulations. This multi-functional compound is engineered to act as a highly effective emulsifier, wetting agent, and foam control additive, bridging the performance gap between silicones and organic polymers. It is essential for formulators in the personal care, coatings, and agrochemical industries seeking to enhance product stability, spreadability, and sensory characteristics. Its unique hybrid structure offers a balance of silicone-derived smoothness and polyether-derived water solubility.

Application

• Personal Care & Cosmetics: A key ingredient in high-performance hair conditioners, skin creams, and sunscreens, where it functions as an emollient, emulsifier, and provides a non-greasy, silky feel.
• Industrial & Institutional Cleaners: Used as a surfactant and wetting agent in hard surface cleaners, car wash formulations, and textile processing aids to improve cleaning efficiency and foam stability.
• Coatings & Inks: Acts as a flow and leveling agent, as well as a defoamer, in water-based paints, printing inks, and industrial coatings to eliminate surface defects and improve finish quality.
• Agrochemicals: Employed as an adjuvant in pesticide and herbicide formulations to enhance droplet spread, adhesion, and penetration on plant surfaces, increasing active ingredient efficacy.
• Polyurethane Foam Production: Serves as a cell opener and surfactant in flexible polyurethane foam manufacturing, ensuring uniform cell structure and stability.
• Textile & Fiber Processing: Utilized as a softener, lubricant, and anti-static agent in fiber spinning and fabric finishing to improve processability and final hand feel.

Quality Control

Our production of this organomodified silicone adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including silicone content, polyether ratio, viscosity, and surface tension. Certificates of Analysis (COA) documenting these specifications are available upon request. We support compliance with relevant global regulatory frameworks for industrial and specialty chemical applications.

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). Keep container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect product performance. Keep away from strong oxidizing agents.
