Description

Isopropylammonium 3-[1,3,3,3-Tetramethyl-1-[(trimethylsilyl)oxy]disiloxanyl]propyl sulphate is a specialized organosilicon quaternary ammonium compound that serves as a highly effective cationic surfactant and coupling agent. This unique chemical structure provides exceptional compatibility with silicone fluids and organic polymers, enabling superior surface modification and emulsification properties. It is primarily utilized in the formulation of high-performance silicone emulsions, textile softeners, and personal care products where durable conditioning and antistatic effects are required.

Application

• Silicone Emulsification: A key cationic emulsifier for creating stable oil-in-water (O/W) emulsions of polydimethylsiloxanes (PDMS) and other silicone oils.
• Textile Finishing: Imparts durable softness, smoothness, and antistatic properties to natural and synthetic fibers in fabric softener formulations.
• Hair & Skin Care: Used in conditioning shampoos, rinse-off conditioners, and lotions to provide excellent combability, shine, and a silky feel.
• Fiberglass Sizing: Acts as a coupling agent and antistatic component in sizing formulations for glass fibers, improving resin adhesion and processability.
• Industrial Surfactant: Functions as a cationic surfactant in specialty cleaning products, metalworking fluids, and as a dispersing aid for pigments.
• Antistatic Coatings: Formulated into coatings for plastics and synthetic films to provide permanent or semi-permanent antistatic protection.
