Polydimethylsiloxane (PDMS) is the most widely used silicon-based organic polymer. It is optically clear, and is generally considered to be inert, non-toxic and non-flammable. PDMS has been assigned CAS number 63148-62-9, and is occasionally called dimethicone. It is one of several types of silicone oil (polymerized siloxane). It is assigned the E number E900 as a food additive.
