Why is it important to know carbonizable substances in white mineral oil or paraffin wax?

This test method is a means for ascertaining whether pharmaceutical mineral oil (ASTM D565) or paraffin wax (ASTM D612) conforms to the standards of the United States Pharmacopeia, the National Formulary, and the Food and Drug Administration.

Summary of the test methods

For the test, either mineral oil (ASTM D565) or melted paraffin wax (ASTM D612) is treated with concentrated sulfuric acid (H₂SO₄) and heated under prescribed conditions. The resulting colour is compared with a reference standard to determine whether it passes or fails the test.
