What is Squalane?
Squalane is the organic compound with the formula ( 2CH[CH2]3CH [CH2]3CH [CH2]2)2. A colorless hydrocarbon, it is the hydrogenated derivative of squalene, although commercial samples are derived from nature. 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.

Introduce at the typical OTC concentration range of 100% pure (or 1% - 10% in formulas). Higher percentages should be reserved for skin that has already built significant tolerance.
