Petrolatum vs. Petroleum Jelly — What's the Difference?

Petrolatum, a semi-solid mixture derived from refining crude oil, serves as a base for various products, including skincare and cosmetic items. Petroleum jelly, a form of petrolatum, is highly refined and purified to meet stringent safety standards, making it suitable for direct skin application. This refinement process is crucial, as it removes potentially harmful compounds, distinguishing petroleum jelly from broader petrolatum-based products.

Both substances are used for moisturizing and protecting the skin, while petroleum jelly's purity makes it a preferred choice for personal care products. It's specifically formulated to be gentle and safe for sensitive skin, whereas petrolatum might be used in a wider range of industrial and less refined applications. The distinction lies in the level of refinement and the intended use of the product.

The terminology can sometimes cause confusion, as "petroleum jelly" is often used to describe any petrolatum-based product intended for skincare. However, not all petrolatum undergoes the rigorous purification process that petroleum jelly does. This is why consumers might find products labeled with either term, but it's the context and the purity levels that truly define their differences.

Regulatory standards also play a significant role in these distinctions. Products marketed as petroleum jelly must meet specific pharmacopeia requirements in many countries, ensuring they are free from impurities and safe for consumer use. This regulatory aspect underscores the importance of distinguishing between petrolatum and petroleum jelly in product labeling and marketing.
