_____ is decolorized petrolatum.

_____ is decolorized petrolatum.

• A. Petrolatum, USP (Vaselin)
• B. White Petrolatum, USP (White Vaseline)
• C. Yellow Ointment, USP
• D. White ointment, USP

Answer: (B)

Decolorized petrolatum refers to petrolatum that has been bleached to remove color-causing impurities, producing a white, colorless to pale base. The term is synonymous with White Petrolatum, USP (White Vaseline), which is specifically identified as decolorized petrolatum. So the best choice is White Petrolatum, USP (White Vaseline) because it is the decolorized form of petrolatum. The other bases are different: Petrolatum, USP (Vaseline) is the unbleached, original petrolatum; Yellow Ointment includes yellow wax and has a yellow tint; White Ointment contains white wax with petrolatum, and its whiteness comes from the wax, not from decolorization of the petrolatum itself.
