Squalane is a hydrocarbon derived by hydrogenation of squalene. In contrast to squalene, due to the complete saturation of squalane, it is not subject to auto-oxidation. This fact, coupled with lower costs associated with squalane, make it desirable in cosmetics manufacturing, where it is used as an emollient and moisturizer. The hydrogenation of squalene to produce squalane was first reported in 1916.
