Description
A yellowish semisolid oil obtained from the fruit around the nuts of the oil palm, Elaeis guineensis, native to Africa. Palm oil is composed of palmitic acid (40.1%), stearic acid (5.5%), oleic acid (42.7%) and linoleic acid (10.3%). It is used in the manufacture of soaps, chocolates, cosmetics, and candles. Palm oil has also been used to dress leather made from goatskins. Oil extracted only from the palm nut is called palm kernel oil and is very similar to coconut oil.
