Description
A thick, yellow oil obtained, along with Spermaceti, from the head of the sperm whale, Physeter macrocephalus or Physeter catadon. Sperm oil is composed of long chain fatty alcohol esters with very little fat. It was used at one time as a lamp oil and was later saponified to make soaps and cosmetics as well as to size textiles. Sperm oil is still used for lubrication and dressing leather. The expensive sperm oil was superior in quality to common Whale oil obtained from the blubber.
