Composition and Properties
Silicone lube uses the element silicon as its base instead of carbon. Like lipid- and petroleum distillate-based lubes, silicone lubes are hydrophobic (repels water), and the lubricity is due to how the silicone molecules glide past one another when applied to the hand/toy and the hole.
Three-to-four different kinds of silicone are mixed in a standard bottle of silicone lube: Dimethicone, Cyclopentasiloxane, Dimethiconol, and Phenyl Trimethicone.
