oil

 [oil]
1. an unctuous, combustible substance that is liquid, or easily liquefiable, on warming, and is not miscible with water, but is soluble in ether. Such substances, depending on their origin, are classified as animal, mineral, or vegetable oils. Depending on their behavior on heating, they are classified as volatile or fixed. For specific oils, see under the name, as castor oil.
2. a fat that is liquid at room temperature.
essential oil volatile o.
expressed oil (fatty oil) (fixed oil) one that is not volatile, i.e., does not evaporate on warming; such oils consist of a mixture of fatty acids and their esters, and are classified as solid, semisolid, and liquid, or as drying, semidrying, and nondrying as a function of their tendency to solidify on exposure to air.
volatile oil an oil that evaporates readily; such oils occur in aromatic plants, to which they give odor and other characteristics.

oil

(oyl),
An inflammable liquid, of fatty consistency and unctuous feel, which is insoluble in water, soluble or insoluble in alcohol, and freely soluble in ether. Oils are variously classified as animal, vegetable, and mineral according to their source (the mineral oils probably being of remote animal and vegetable origin); into fatty (fixed) and volatile oils; and into drying and nondrying (fatty) oils, the former gradually thickening when exposed to the air and finally drying to a varnish, the latter not drying but liable to become rancid on exposure. Many of the oils, both fixed and volatile, are used in medicine. For individual oils, see the specific names.
