Laxative mineral oil is Pharmaceutical grade (USP)

Food-grade mineral oil lubricants for food machinery contain corrosion inhibitors, foam suppressants and anti-wear agents, even though they are authorized for contact with food. Pharmaceutical-grade mineral oil has to be free of all impurities under USP standards.
