Shark infested olive oil
June 17, 2010
Squalene and squalane are oils, often used in the production of cosmetics and vaccines. Originally derived from the liver oil of deepwater sharks, squalane is also available from olives, and since 2008 some important cosmetic firms have claimed to switch to this more ethical squalane supply. However, the shark oil offers a higher yield and lower costs, so suppliers face the temptation to disguise the oil?s origin, while continuing to exploit sharks. A method in Rapid Communications in Mass Spectrometry is reported to reveal the source, protecting sharks, as well as cosmetic firms and consumers.
