Cyclosiloxanes (D4 and D5)

Cyclosiloxanes, or cyclic siloxanes, are basic raw material members of the broad family of silicone materials.  These low viscosity basic silicones are clear and odorless and often used as intermediates in the production of silicone rubbers, gels and resins.  Cyclosiloxanes also are used as minor ingredients in silicone formulations for industrial and personal care applications, functioning as carrying agents and wetting agents.  In Personal Care applications, these products are referred to as cyclomethicones.
