Ethyl trisiloxane

Ethyl trisiloxane (CAS 17861-60-8) is a short-chain silicone fluid used across industrial and personal care markets as a low-viscosity carrier, wetting agent, and surface modifier. Its siloxane backbone delivers fast spreading and substrate penetration where conventional solvents fall short.

In textile and leather processing, it improves active ingredient penetration and surface uniformity in finishing formulations. Automotive and metalworking lubricant formulators use it as a carrier fluid to enhance the deposition and spreading of functional additives on metal surfaces.

Personal care formulators incorporate it into leave-on and rinse-off products where lightweight, non-greasy skin feel and even distribution of actives are required. In paper treatment and release coating systems, it functions as a surface modifier to control wettability.

This material is highly effective at reducing interfacial tension across various substrates. Ethyl trisiloxane is supplied as a clear, low-viscosity liquid and is available in technical grade for diverse industrial applications.

Packaging options typically range from small drums to IBC quantities depending on volume requirements. Buyers should confirm purity specifications and batch documentation directly with the supplier to ensure compliance with specific project needs.

Grade designations can vary between manufacturers, so technical data sheets should be reviewed carefully. This versatile silicone fluid remains a staple for formulators seeking high-performance spreading and carrier properties in modern chemical manufacturing.
