Mineral oils, also known as petroleum oils, are a diverse group of hydrocarbon-based products derived from crude oil. They are characterized by their nonpolar nature, making them insoluble in water but soluble in organic solvents. The composition of mineral oils varies depending on the refining process and the source crude oil, but they typically consist of alkanes, cycloalkanes, and aromatic hydrocarbons.

Mineral oils find extensive use across numerous industries. In lubricants, they reduce friction and wear between moving parts in engines, machinery, and industrial equipment. In the cosmetic and personal care industry, refined mineral oils serve as emollients, moisturizers, and bases for products like lotions, creams, and baby oil. They are also utilized as solvents in paints, varnishes, and inks, as well as in the production of waxes, greases, and asphalt.

The classification of mineral oils is often based on their refining degree and intended application. For instance, highly refined mineral oils are used in food-grade applications and pharmaceuticals due to their purity and low toxicity. However, less refined mineral oils can contain impurities that may pose health or environmental concerns.

Environmental considerations are important when discussing mineral oils. Spills can contaminate soil and water, and their combustion can release pollutants into the atmosphere. Regulations exist to manage their production, use, and disposal to mitigate these impacts. Ongoing research explores bio-based alternatives and more sustainable refining processes to reduce reliance on petroleum-derived products.
