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.
It is composed mostly of wax esters (chiefly cetyl palmitate) and a smaller proportion of triglycerides. [9] Unlike other toothed whales, most of the carbon chains in the wax esters are relatively long (C 10 −C 22). [4] The blubber oil of the whale is about 66% wax. [4] When it cools to 30 °C or below, the waxes begin to solidify. [10]
Sperm oil cannot be easily hydrogenated, and thus could not be used to make soap or margarine. [14] [15] It is fairly resistant to oxidization. [16] Spermaceti is a liquid wax, composed mostly of wax esters (chiefly cetyl palmitate) and a smaller proportion of triglycerides, [17] with oleic acid being the most common fatty acid. The proportion ...
Emerging industrial societies used whale oil in oil lamps and to make soap.In the 20th century it was made into margarine.There is a misconception that commercial development of the petroleum industry and vegetable oils saved whales from extinction. [2]

Total fatty matter (TFM) is one of the most important characteristics describing the quality of soap and is always specified in commercial transactions. It is defined as the total amount of fatty matter, mostly fatty acids, that can be separated from a sample after splitting with a mineral acid, usually hydrochloric acid.
