Mineral Oil (white oil, CAS 8042-47-5) is a highly refined, colorless, odorless petroleum oil with a specific gravity of about 0.83 to 0.89 and a high flash point. Food and pharmaceutical grades are used as release agents, laxatives and in cosmetics and baby oil; technical grades are used as lubricants, transformer and dielectric fluids, and in plastics processing. Mineral oil storage needs containment but little special handling. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
HDPE is the most economical tank material for Mineral Oil, rated Excellent. Polypropylene, nylon and PVDF (Kynar®) are also rated Good or better. Avoid EPDM gaskets.
