Lignoceric fatty acid (aka tetracosanoic acid), a very long, straight-chain, saturated fatty acid with 24 carbon atoms (C24:0) and no double bonds. It’s a fatty acid also found in beeswax and rice bran wax and has a melting point of 84.2˚C (183.6˚F), which is pretty high. It’s almost waxy in nature, and makes the oil a bit thicker. It’s also found in pracaxi oil, used to increase friction between hair strands.
It’s considered a very long chain fatty acid because it has 24 carbon atoms.
