Paraffinum Liquidum – Glossary

Short definition

Paraffinum liquidum is a mineral oil used in cosmetics as a nourishing and protective ingredient. It forms an occlusive film on the skin and reduces moisture loss.

What is paraffinum liquidum?

Paraffinum Liquidum is the INCI name for liquid paraffin, also known as mineral oil or white oil. Derived from petroleum, paraffinum liquidum undergoes extensive purification in the cosmetics industry to be used as a skin-friendly ingredient. Due to its occlusive properties, paraffinum liquidum forms a protective film on the skin, preventing transepidermal water loss.

In creams, ointments, lip balms, and baby products, paraffinum liquidum serves as a replenishing and emollient ingredient. It hardly reacts with other ingredients, has a long shelf life, and is oxidation-stable. Unlike plant oils, paraffinum liquidum does not penetrate deeply into the skin but primarily acts on the surface as a protective barrier. In the EU, the use of paraffinum liquidum in cosmetic products is regulated and only permitted in highly refined form.
