Pristane (from lat. Pristis = sea monster) forms a transparent oily liquid. Pristane is a branched alkane compound with the molecular formula C19H40, a naturally occurring saturated hydrocarbon.

Pristane is a component of mineral oils. The substance is produced by bacteria, algae and higher plants. Pristane can also be found in wool fat, crabs, fish (especially in shark liver oil) and whales. Pristane is used in technical areas (as lubricant, corrosion protection or transformer oil). In cosmetics, pristans are used in formulations. The substance acts as an emollient (makes the skin smooth and supple).
