Benzine, Naptha and Ligroin are 3 synonyms for the same thing. They are roughly equal to Gasoline which contains so many additives that it looks and smells quite different. Any alteration of the formula would be difficult and might render the product useless for cleaning applications.
BTW BENZINE is not the same as BENZENE. The former is a mixture like Naptha, and the latter is a pure organic molecule with a totally different structure than any of the ingredients in BENZINE.
