What it is
Tetradecane is a saturated 14-carbon hydrocarbon that is liquid at room temperature and chemically inert. In cosmetics it serves as a light, spreadable emollient and as a solvent or carrier for oil-soluble ingredients, giving a smooth, fast-absorbing skin feel. In sprays and lotions it can help thin the oil phase and improve application.
Safety & warnings
Tetradecane is chemically stable and is not a common sensitizer. As a hydrocarbon emollient it is generally non-irritating, though as with other light hydrocarbons it is primarily an emollient/solvent and contributes little active benefit.
Origin & sourcing
Synthetic or petrochemical. It is a defined alkane that can be derived from petroleum fractions or produced synthetically.
