Squalane is a natural hydrocarbon and triterpene derived from a variety of plant and animal sources. It is a component of human sebum. Squalane is a saturated analog of squalene, from which it can also be produced by hydrogenation.
The chemically inert nature of squalane makes it useful in cosmetic applications, where it is used as an emollient and moisturizer.[2] Squalane has low acute toxicity and is not an irritant at concentrations used in cosmetics.[3]
