Description
A colorless, nondrying oil or white, semisolid fat extracted from the dried meat of the Coconut fruit (copra) obtained from the tropical palm Cocus nucifera. Coconut oil contains the glycerides of lauric (45.4%), capric (8.4%), myristic (18.0%), palmitic (10.5%), stearic (2.3%), and oleic (7.5%) acids. It is used commercially to make candy, cosmetics, soaps, emulsions, and leather cleaners. Coconut oil has also been used in gold tooling to adhere gold leaf prior to impressing a heated tool or die (Roberts and Etherington 1982).
