Ethyl trisiloxane

Ethyl trisiloxane (CAS 17861-60-8) is a short-chain silicone fluid used as a low-viscosity carrier, wetting agent, and surface modifier.

Where is Ethyl trisiloxane used?

• Textile and leather: improves active ingredient penetration and surface uniformity in finishing formulations
• Automotive and metalworking lubricants: carrier fluid enhancing deposition and spreading of functional additives on metal surfaces
• Personal care: lightweight, non-greasy skin feel and even distribution of actives in leave-on and rinse-off products
• Paper treatment and release coatings: surface modifier controlling wettability
• Its siloxane backbone delivers fast spreading and substrate penetration.

Good to know: Grade designations can vary between manufacturers, so technical data sheets should be reviewed carefully. Buyers should confirm purity specifications and batch documentation directly with the supplier.
