neat's-foot oil
A pale yellow, fatty oil produced by boiling the
feet and shin bones of cattle, horses, sheep, and
pigs, and skimming the oil from the surface of the
water. Like all natural fats, neat's-foot oil is a
mixture of substances, many of which deposit on
cooling. "Cold-tested" neat's-foot oil is a
material that has been held at the freezing point
for a period of time and then filtered.
Neat's-foot oil is used in the preparation of some
leather dressings, and in the fatliquoring of
leather. (143 )
