Sperm whaling is the hunting of sperm whales for a substance called spermaceti which was used in cosmetics, leatherworking, and lubricants. ==Economic motivation==
The head of the sperm whale is filled with a waxy liquid called spermaceti. This liquid can be refined into spermaceti wax and sperm oil. These were much sought after by 18th, 19th and 20th century whalers. These substances found a variety of commercial applications, such as candles, soap, cosmetics, machine oil, other specialized lubricants, lamp oil, pencils, crayons, leather waterproofing, rust-proofing materials and many pharmaceutical compounds. 〔(【引用サイトリンク】url=http://www.aquariumofpacific.org/onlinelearningcenter/print/sperm_whale/ )〕 Ambergris, a solid, waxy, flammable substance produced in the digestive system of sperm whales, was also sought as a fixative in perfumery.
