Description

A high molecular weight hydrocarbon wax that has a fine crystalline structure. Microcrystalline waxes were first made in the late 1930s by Baker Petrolite in Barnsdall, Oklahoma. It is the remaining fraction of paraffin wax after the lower molecular weight waxes are removed. Microcrystalline wax is chemically inert, and in general, a stronger adhesive than paraffin wax. It can be softened by adding mineral oil or petroleum jelly. Microcrystalline wax does not emulsify easily but can be modified with a catalyst to produce an oxidized, emulsifiable form that is used in hard, self-polishing floor wax. Microcrystalline wax is used in laminating paper and foils as well as for polishes. It polishes to a glass clear, smooth, non-sticky finish.

See also mineral wax.
