Mineral Oil (Paraffinum Liquidum) / Petrolatum
What is Mineral Oil (Paraffinum Liquidum) / Petrolatum?
Mineral oil and petrolatum are byproducts of the refining process to produce gasoline from crude oil. They are purified and used in a variety of personal care products.
Mineral oil is often used as a moisturizing agent because it forms a barrier on the skin, which helps to retain moisture. Petrolatum, commonly known as petroleum jelly, is used for similar reasons and is valued for its emollient properties. There is some debate in the scientific community about the potential irritant effects, but high-grade versions are considered safe for topical use.
When you see mineral oil or petrolatum on a label, it generally indicates that the product aims to provide moisture retention and protection. These ingredients are approved for use in cosmetics but may not be suitable for everyone, especially those looking for plant-based alternatives.
Commonly found in: Moisturizers, Lotions, Hair Care Products, Lip Balms, Creams
What to watch
- Some studies suggest mineral oil may cause skin irritation in sensitive individuals.
- Low-quality grades of mineral oil could potentially contain impurities.
Benefits

Mineral oil and petrolatum are considered safe for use in cosmetics by the FDA. They are often used in over-the-counter skin products.
While high-grade mineral oil is generally safe, there are concerns about impurities in lower-quality forms, and some research points to skin irritation risks.
As petroleum derivatives, mineral oil and petrolatum are technically vegan but are not plant-derived, which may concern some vegans.

Scout's take
Mineral oil and petrolatum are petroleum-derived occlusives. Cosmetic-grade versions are generally low-risk on the skin but provide no nutritional benefit and may contain trace polycyclic aromatic hydrocarbons depending on refining grade. They serve mainly as carrier base and moisture barrier in this product.
