EspañolWHALE OIL
'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.
