Are essential oils oily?
Essential oils are not oily although some of the thicker oils appear so. Most essential oils lack viscosity and will actually dissipate if held in the palm of the hand for some time (exceptions include vetiver, sandalwood, benzoin, vanilla, Peru balsam, cedarwood, and other woody and resinous oils). On the whole they have a very fine consistency and molecular make up and should be differentiated from fatty oils such as canola or grapeseed oil.
