When it comes to paint, there are two main types of liquids that can be used: mineral oil and mineral spirits. Both have their own unique benefits and drawbacks, which this article will explore in detail. By the end of it, you should have a good understanding of which type of paint is best for your needs.
What is Mineral Oil?
Mineral oil is a clear, odorless liquid that is derived from petroleum. It has a number of uses, including as a lubricant, a food additive, and an ingredient in cosmetics and skincare products. Mineral oil is also used as a paint thinner and solvent.
Chemistry of Mineral Oil
Mineral oil is a hydrocarbon compound, which means that it is made up of hydrogen and carbon atoms. The carbon atoms in mineral oil are arranged in a chain, with the hydrogen atoms attached to them. The length of the chain varies, but most mineral oils have between 10 and 20 carbon atoms.
The boiling point of mineral oil is 350 degrees Fahrenheit, and the freezing point is -58 degrees Fahrenheit.
What are Mineral Spirits?
Mineral spirits are a type of petroleum distillate that is used as a paint thinner and solvent. Unlike mineral oil, which is clear and odorless, mineral spirits have a strong odor and are typically yellow or green in color.
Chemistry of Mineral Spirits
Mineral spirits are a type of aliphatic solvent, which means that they are made up of molecules that have a straight or branched chain structure. The chains in mineral spirits can be anywhere from six to 12 carbon atoms long.
The boiling point of mineral spirits is 400 degrees Fahrenheit, and the freezing point is -60 degrees Fahrenheit.
What are Common Differences?
There are many differences between mineral oil and mineral spirits, but some of the most notable ones are listed below.
- Derivation: Mineral oil is derived from petroleum, whereas mineral spirits are derived from coal tar.
- Flammability: Mineral oil is not flammable, while mineral spirits are highly flammable.
- Viscosity: Mineral oil is more viscous than mineral spirits.
- Uses: Mineral oil is commonly used as a lubricant and a rust preventative, while mineral spirits are used as solvents and degreasers.
- Odor: Mineral oil has very little odor, while mineral spirits have a strong, pungent odor.
- Flashpoint: Mineral oil has a high flash point, while mineral spirits have a low flash point.
- Evaporation rate: Mineral oil has a slow evaporation rate, while mineral spirits have a fast evaporation rate.
How Are Mineral Oil and Mineral Spirits Used?
Mineral oil and mineral spirits both have a wide range of uses in different industries.
Mineral Oil

Mineral Spirits Substitute
In terms of a mineral spirits substitute, you can use white spirit or petroleum distillate. They’re both derived from crude oil and have very similar chemical compositions.
The big difference is that white spirit is fully refined, whereas petroleum distillate isn’t. As such, white spirit is the better choice for cleaning, as it’s less likely to leave behind residue.
However, petroleum distillate is often cheaper, so it may be the better choice if you’re on a budget.
