Microcrystalline waxes differ from refined paraffin wax in that the crystal structure is more branched and the carbon chains are longer. These waxes are tougher, more flexible and have higher tensile strengths and melting points. They are also more adhesive, and they bind solvents, oil, etc., and thus prevent the sweating-out of compositions. Typical oil content by weight is between 0.5% and 2%.
