Is Mineral Oil banned?
Mineral Oil is permitted by the US FDA. Several countries restrict, warning-label, or have reviewed it for safety concerns. The US has more lenient additive rules than the EU, UK, Canada, and Japan, which is why this ingredient remains widely used here.
Why Mineral Oil is flagged
EFSA has raised significant concerns about mineral oil hydrocarbons (MOH) contamination in food through two pathways: (1) deliberate food-grade mineral oil use in coatings and processing, and (2) migration from recycled paper and cardboard food packaging into food. MOH comprises two types: mineral oil saturated hydrocarbons (MOSH), which accumulate in human adipose tissue, liver, and spleen, and mineral oil aromatic hydrocarbons (MOAH), which include polycyclic aromatic hydrocarbons (PAHs) that are potentially carcinogenic. A 2011 Swiss study found mineral oil hydrocarbons in human liver and spleen samples from autopsy, demonstrating real bioaccumulation. EFSA's 2023 preliminary opinion identified MOAH contamination in food as a safety concern that cannot be dismissed, recommending ALARA (as low as reasonably achievable) minimization. Untreated and mildly treated mineral oils are IARC Group 1 human carcinogens for occupational inhalation. Highly refined food-grade mineral oil (E905) is not classified as a direct carcinogen, but MOAH contamination in even food-grade mineral oil is an ongoing concern.
