sperm oil
A pale yellow oil found with spermaceti in the
cachalot (sperm) whale, Physeter macrocephalus.

hot water, the sperm oil is pressed out. It is
classed chemically as a liquid wax and is
sometimes used as a lubricant for leather
bindings, generally with other materials in LEATHER DRESSINGS .
