Oil \oil\ (oil), n. [OE. oile, OF. oile, F.
huile, fr. L. oleum; akin to Gr. ?. Cf. Olive.]
- A slippery or viscous liquid or liquefiable substance not
miscible with water
- Paint used by an artist [syn: oil color]
- Any one of a great variety of unctuous combustible substances,
not miscible with water; as, olive oil, whale oil, rock oil, etc.
They are of animal, vegetable, or mineral origin and of varied
composition, and they are variously used for food, for solvents,
for anointing, lubrication, illumination, etc. By extension, any
substance of an oily consistency; as, oil of vitriol.
Note: The mineral oils are varieties of petroleum. The vegetable
oils are of two classes, essential oils, and natural oils which in
general resemble the animal oils and fats. Most of the natural oils
and the animal oils and fats consist of ethereal salts of glycerin,
with a large number of organic acids, principally stearic, oleic,
and palmitic, forming respectively stearin, olein, and palmitin.
Stearin and palmitin prevail in the solid oils and fats, and olein
in the liquid oils; Mutton tallow, beef tallow, and lard are rich
in stearin, human fat and palm oil in palmitin, and sperm and
cod-liver oils in olein. In making soaps, the acids leave the
glycerin and unite with the soda or potash.
