Not to be confused with squalene.
Squalane is the organic compound with the formula ((CH3)2CH(CH2)3CH(CH3)(CH2)3(CH2)3CH(CH3)(CH2)2)2. A colorless hydrocarbon, it is the hydrogenated derivative of squalene, although commercial samples are derived from nature.[3] In contrast to squalene, due to the complete saturation of squalane, it is not subject to auto-oxidation. This fact, coupled with its lower costs and desirable physical properties, led to its use as an emollient and moisturizer in cosmetics.[4]
