Paraffin is a byproduct of the refining process for petrolium oils. Paraffin wax is not kerosene, mineral oil is not kerosene and yet they both have paraffin in them. Paraffin is found in mineral oil, wax, and several other products and certain paraffins can be found in kerosene.
Did you know that Jet Fuel is just purified kerosene and contains paraffins? :p
