Summary

Dimethicone, also called Polydimethylsiloxane (PDMS), belongs to a group of polymeric organosilicon substances that are commonly referred to as silicones. Dimethicone is the most widely used silicon-based organic polymer, and is particularly known for its strange rheological (or flow) properties. It is optically clear, and, in general, is considered to be inert, non-toxic and non-flammable
