Mineral oil, or paraffin oil, is a mixture of higher alkanes from a mineral source, such as petroleum. Petroleum mineral oil is manufactured from crude oils by vacuum distillation to produce several distillates and a residual oil that are then further refined. During the modern refining process, aromatics are reduced by solvent extraction, catalytic hydrotreating, or hydrocracking. Unrefined or mildly treated mineral oils are classified as Group 3 carcinogens by the World Health Organizations, as chronic exposure to these aromatics including alkylated polycyclic aromatic compounds (PAC) can lead to skin cancer.

Mineral oil is a common ingredient in baby lotions, cold creams, ointments and cosmetics to treat and prevent dry, rough, scaly, itchy skin and minor skin irritations. It is also used as a mild laxative for human or veterinary uses.

Mineral oil blocks the loss of water from the skin allowing greater hydration of the epidermis 2.

Mechanism of action

Mineral oil sits on the surface of the skin and in spaces between cells and provides a hydrophobic barrier 2. This barrier prevents trans-epidermal water loss to trap water in the skin. Overall this leads to greater hydration, flexibility, and softness of the stratum corneum.
