Cyclicdimethylpolysiloxane (DMC), often referred to simply as Cyclomethicone, is a blend of cyclic dimethylsiloxane oligomers, primarily D4 (Octamethylcyclotetrasiloxane), D5 (Decamethylcyclopentasiloxane), and D6 (Dodecamethylcyclohexasiloxane). It is a **clear, colorless, odorless, and volatile silicone fluid**. Its unique combination of properties, including excellent spreadability, a non-greasy feel, and rapid evaporation, makes it an indispensable component in a multitude of formulations.
