(gcide) | Oil \Oil\ (oil), n. [OE. oile, OF. oile, F. huile, fr. L. oleum;
akin to Gr. ?. Cf. Olive.]
Any one of a great variety of unctuous combustible
substances, more viscous than and 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.
[1913 Webster]
Note: The mineral oils are varieties of petroleum. See
Petroleum. The vegetable oils are of two classes,
essential oils (see under Essential), 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.
