Cetyl palmitate

Hexadecyl hexadecanoate, also known as cetyl palmitate, is the ester derived from hexadecanoic acid and 1-hexadecanol. This white waxy solid is the primary constituent of spermaceti, the once highly prized wax found in the skull of sperm whales.[2] Cetyl palmitate is a component of some solid lipid nanoparticles.
