Squalane is a widely used ingredient in cosmetics, personal care, and skincare formulations. Depending on its function, it may serve as a moisturizer, preservative, emulsifier, or active ingredient to enhance the overall effectiveness and performance of a product.
Squalane (Wikipedia)
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. 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.
