Dimethyl silicone oil (polydimethylsiloxane) is a clear, colorless silicone fluid with a kinematic viscosity of 100 cSt at 25 °C (CAS 63148-62-9). It is an inert, low-volatility laboratory reagent used where a defined silicone medium is required, including as viscosity standards, lubricants, anti-foaming agents, and hydrophobic treatments. Supplied in a 25 mL bottle for small-scale laboratory use.
