Microcrystalline wax

Such waxes are formed from regular, close-packed polymer chains, which form crystals. Wax can be considered a low molecular version of polyethylene. Microcrystalline wax is composed of mainly highly branched and irregular molecules. In conservation use, microcrystalline wax is mixed with paraffin wax and a solvent (usually white spirit) to provide the working qualities desired. 'Renaissance Wax' and 'Cosmolloid' are the trade names of one variety.
