INCI name
Squalane
Also listed as: Hydrogenated squalene
Squalane is a light, stable hydrocarbon oil. It is the hydrogenated form of squalene, which is found in shark liver oil and also in some plants, including olives, sugarcane-derived farnesene routes, and amaranth. Almost all new cosmetic squalane is plant-derived. The INCI name is simply Squalane, so the source is not on the label unless the brand says so elsewhere.
Squalene (with an e) is the unsaturated precursor and oxidises more readily. Squalane (with an a) is the saturated, more stable form used in most modern bottles.
