Vaseline
Definition:
(n.) A yellowish translucent substance, almost odorless and tasteless, obtained as a residue in the purification of crude petroleum, and consisting essentially of a mixture of several of the higher members of the paraffin series. It is used as an unguent, and for various purposes in the arts. See the Note under Petrolatum.
