Spermaceti is created in the spermaceti organ inside the whale's head. This organ may contain as much as 1, litres US gal of spermaceti.

Sperm oil is a waxy liquid obtained from sperm whales. It is a clear, yellowish liquid with a very faint odor.

It is composed of wax esters with a small proportion of triglycerides , an ester of an unsaturated fatty acid and a branched-chain fatty alcohol.
