Mineral Oil & Petrolatum: why to avoid them and what to use instead
Fossil-derived and, if insufficiently refined, potentially contaminated with mineral oil aromatic hydrocarbons (MOAH) — a class that includes carcinogens.
The short answer
Pharmaceutical-grade petrolatum is one of the safest and most effective occlusives available, and dermatologists rightly recommend it. The stronger objections are fossil sourcing and refining transparency, not skin safety.

What regulators have actually done
The EU requires cosmetic-grade petrolatum to have a fully known refining history that excludes carcinogenic residues. Germany's BfR has repeatedly flagged MOAH contamination in cosmetic and food-contact mineral oils.
The refining question is the whole question
Unrefined petroleum fractions contain polycyclic aromatic hydrocarbons. Cosmetic and pharmaceutical grades are refined to remove them, and EU law requires the full refining history to be documented. In practice, products from regulated markets are extremely unlikely to expose you to MOAH; imported and unregulated products are the risk case.
Why people avoid it anyway
For most shoppers the decision is about petroleum sourcing rather than toxicity — mineral oil is a fossil by-product, and plant-derived occlusives do the same job. Squalane from olive or sugarcane is the closest functional match for facial use.
Mineral Oil & Petrolatum: frequently asked questions
Does petrolatum clog pores?+
It's classified as non-comedogenic in most testing. Breakouts attributed to it usually come from trapping other products underneath.
Is petroleum jelly vegan?+
The base is mineral, so yes — but many balms combine it with beeswax or lanolin, so read the full list.
