Paraffin waxes are separated from crude oil during the production of light (distillate) lubricating oils. These waxes are categorized by oil content and the degree of refinement. The crudest versions fall into the slack wax category and contain between 5% to 20% oil. Next on the step of refinement are scale waxes containing between 1% to 5% oil.

The resulting waxes are water clear, odor free, and normally food grade.
