Description

Siloxanes And Silicones, Di-Me, Mixed Cetyl Group- And 3-Hydroxypropyl Group-Terminated, Ethoxylated Propoxylated CAS NO 219916-63-9 is a specialized organomodified silicone surfactant engineered for superior surface activity and compatibility. This compound matters for formulators seeking to enhance the performance, feel, and stability of personal care and industrial products through its unique dual-functional terminal groups. It is primarily needed by manufacturers in the cosmetics, coatings, and textile industries for its emulsifying, conditioning, and spreading properties.

Application

• Personal Care Emulsions: Acts as a key emulsifier and stabilizer in creams, lotions, and sunscreens, providing a smooth, non-greasy skin feel.
• Hair Conditioners & Treatments: Imparts excellent detangling, softness, and shine as a conditioning agent in rinse-off and leave-in formulations.
• Industrial Lubricants & Release Agents: Serves as an additive to improve lubricity and mold release in plastic and rubber processing.
• Textile Softeners & Finishes: Used to confer a soft, luxurious hand feel to fabrics and improve fiber processability.
• Coatings & Inks: Functions as a flow and leveling agent to reduce surface defects and enhance substrate wetting.
• Agricultural Adjuvants: Employed as a surfactant to improve the spreading and adherence of pesticides and fertilizers on plant surfaces.
• Polyurethane Foam Stabilization: Aids in cell structure control and stabilization during flexible and rigid foam production.
