Description

Siloxanes And Silicones, Di-Me, Me 3-(1-Oxoeicosyl)Oxypropyl is a specialized organomodified silicone compound, distinguished by its long-chain eicosanoyl (C20) fatty acid derivative group. This unique structure provides a powerful combination of silicone fluidity and organic compatibility, making it an exceptional additive for modifying surface properties and enhancing performance. It is a critical material for formulators in the personal care, coatings, and industrial lubricant sectors seeking to achieve superior slip, water repellency, and surface conditioning.

Application

• Personal Care & Cosmetics: Acts as a premium emollient and conditioning agent in hair care products (shampoos, conditioners) and skin creams, providing exceptional smoothness and shine without greasiness.
• Release Agents & Mold Lubricants: Used in plastic, rubber, and composite manufacturing to create non-stick surfaces for easy demolding and clean part release.
• Textile & Fiber Treatment: Imparts durable softness, lubricity, and water repellency to synthetic and natural fibers during finishing processes.
• Industrial Lubricants & Greases: Serves as a high-performance additive to enhance lubricity, reduce friction, and improve thermal stability in specialty formulations.
• Coatings & Inks: Functions as a flow and leveling agent, as well as a slip additive, to improve surface smoothness, scratch resistance, and gloss in final coatings.
• Polishes & Waxes: A key ingredient in automotive and furniture polishes to provide deep gloss, water beading, and protective film formation.
