Squalane, vegetable is a clear, colorless liquid that has a characteristic odor. It is a naturally occurring hydrocarbon made from the unsaponifiable matter of olive oil. It protects the skin against loss of moisture, makes it elastic and pliant, and thereby improves the structure of the natural lipid film. Due to its excellent penetration properties, Squalane is also used as a carrier for active substances. In cosmetics, it is mostly used as a quickly spreading, non-irritating lipid, stable against oxidation, in skin emulsions, sunscreens, foundations, and haircare products. It is also often used in cosmetic formulations as a natural hydrocarbon to replace synthetic and petroleum-based hydrocarbon mixtures.
