摘要

Squalene is a popular ingredient for use in cosmetics and oil-based health capsules. The substance is primarily derived from the livers of sharks - hence its name, as it is found in the Saualus genus of shark - but it is also present in the livers ofmammals (including human), the stomach oil of some birds and in some plants. Its health-benefiting properties have been celebrated for centuries. For example, shark liver oil was first named in a Chinese compendium of traditional remedies dating back tothe 16th century.
