'Whale oil' is the oil obtained from the
blubber of various species of
whales of the genus ''
Balaena'', such as ''B. mysticetus'', Greenland or
Right Whale (Northern whale oil), ''B. australis'' (southern whale oil), ''Balaenoptera longimana'', ''Balaenoptera borealis'' (
Fin oil, Finner whale oil,
Humpback oil). The
Orca and the
Beluga also yield whale oils. Train oil proper is the northernwhale oil, but this term has been applied to all blubber oils, and in
Germany, to all marine animal oils: fish oils, liver oils, and blubber oils. The most important whale oil is sperm or
spermaceti oil, yielded by the
Sperm Whales.
Whale oil is chemically a liquid
wax and not a true oil. It flows readily, is clear, and varies in colour from a bright honey yellow to a dark brown, according to the condition of the blubber from which it has been extracted.
Stearin and
spermaceti may be separated from whale oil at low temperatures; at under 0°C these constituents may be almost completely crystallized and filtered out. When removed and pressed, this deposit is known as whale
tallow, and the oil from which it is removed is known as pressed whale oil; yet is sometimes passed as sperm oil.
The first principal use of whale oil was as an illuminant in
lamps and as candle wax. Whale oil later came to be used in oiling
wools for combing and other uses. It was the first of any animal or mineral oil to achieve commercial viability. It was also used to heal soldiers' wounds in war.
However, with the 1986
International Whaling Commission (IWC) moratorium on commercial whaling, whale oil has all but ceased to be viable, as substitutes have been found for most of the uses of whale oil, most notably
jojoba oil.
