Microcrystalline Wax is a mixture of hydrocarbons of 35-50 carbons per molecule and 500-700 molecular weight. The following are grades of Microcrystalline Wax.
Paraffin wax is a mixture consisting mostly of straight chain hydrocarbons, with about 20 - 35 carbons in the molecule and a molecular weight of about 300 - 500.
Petroleum jelly, petrolatum or soft paraffin is a semi-solid mixture of hydrocarbons, is regularly being used for manufacturing Ointment and Vaseline due to its healing properties.
