This inherent stability makes refined mineral oil an ideal base for medicinal ointments, where preservation is critical, and for high-performance industrial lubricants that must endure extreme temperatures without breaking down. The long carbon chains (high 'n' values) intertwine, creating a dense, viscous liquid that resists flow.
Highly Refined White Mineral Oil HVO: Understanding Its Composition and Purity
For pharmaceutical and food-contact applications, the mineral oil chemical formula is effectively a defined mixture of saturated C 15 to C 22 alkanes, ensuring it is inert, non-toxic, and free from contaminants that could affect safety. Through a sophisticated process of fractional distillation and further purification—such as hydrogenation and acid treatment—the heavier hydrocarbon fractions are isolated and refined.
This characteristic is why mineral oil feels slick and coats surfaces effectively, providing a barrier function. This meticulous process removes unwanted impurities and polishes the mixture into a state of high purity, resulting in the light, stable liquid recognized as USP (United States Pharmacopeia) or cosmetic grade mineral oil.

Because they lack double bonds, paraffinic hydrocarbons are less prone to oxidation and degradation compared to other hydrocarbon types. Physical Properties Derived from Molecular Structure The linear, saturated structure of the alkanes in mineral oil directly dictates its physical behavior.
