PFAD (palm fatty acid distillate) is a by‐product of physical refining of crude palm oil products and is composed of free fatty acids (81.7%), glycerides (14.4%), squalene (0.8%), vitamin E (0.5%), sterols (0.4%) and other substances (2.2%). PFAD is used in the animal feed and laundry soap industries as well as a raw material for the oleochemicals industry. Vitamin E, squalene and phytosterols are value‐added products which could be extracted from PFAD and are of potential value for the nutraceutical and cosmetic industries.
