Is Mineral Oil Flammable? The Truth behind its Combustibility


Mineral oil is a commonly used substance in various household and industrial products. However, there has been some confusion and concern about its flammability. In this article, we will dive deep into the properties of mineral oil to understand whether it is flammable or not.

Is Mineral Oil Flammable? The Truth behind its Combustibility

What is Mineral Oil?

Mineral oil is a colorless and odorless liquid derived from petroleum. It is made up of hydrocarbons, which are organic compounds composed of carbon and hydrogen atoms. Due to its purity and low reactivity, mineral oil is widely used in many different industries.

Flammability of Mineral Oil

Mineral oil is considered to be non-flammable. This means that it does not catch fire easily and does not support combustion. However, it is essential to note that the term “flammable” can be misleading, as even non-flammable substances may support combustion under certain conditions.

While mineral oil itself does not burn, it can become a fire hazard when it comes into contact with an open flame or a high-temperature surface. The main concern arises from the fact that mineral oil has a relatively low flash point.

What Is A Flash Point?

The flash point of a substance is the lowest temperature at which it can emit vapors that will ignite when exposed to an open flame or spark. In the case of mineral oil, its flash point generally ranges from 170 to 200 degrees Celsius (338 to 392 degrees Fahrenheit).

It is important to handle mineral oil with caution around potential ignition sources, such as hot surfaces, sparks, or flames. Repeated exposure to high temperatures can gradually lower the flash point of mineral oil, increasing the risk of it catching fire.

Safe Handling And Storage Of Mineral Oil

To ensure safety when working with mineral oil, it is crucial to follow proper handling and storage guidelines:

  • Keep mineral oil containers tightly closed when not in use to prevent the evaporation of flammable vapors.
  • Avoid exposing mineral oil to open flames or sparks.
  • Store mineral oil in a cool, well-ventilated area away from heat sources.
  • Do not smoke or use open flames in areas where mineral oil is being used or stored.

By adhering to these precautions, the risk of a fire or accident involving mineral oil can be significantly reduced.

Applications of Mineral Oil

Mineral oil has a wide range of applications in various industries, including:

  1. Pharmaceuticals: Mineral oil is often used in the production of ointments, lotions, and creams, providing a moisturizing and protective barrier for the skin.
  2. Cosmetics: It is a common ingredient in skincare, haircare, and makeup products such as lip balms, moisturizers, and mascaras.
  3. Mechanical: Mineral oil is used as a lubricant in machinery to reduce friction and prevent wear and tear.
  4. Furniture: It can be used to nourish and rejuvenate wooden furniture, giving it a polished and glossy appearance.
  5. Food Industry: In food processing, mineral oil can be used as a lubricant for food machinery or as a release agent to prevent sticking.

It is important to note that food-grade mineral oil should be used for applications involving direct contact with food. This type of mineral oil is refined to meet safety standards and is free from impurities and harmful contaminants.

FAQs On Is Mineral Oil Flammable

Is Mineral Oil Flammable?

Yes, mineral oil is flammable and should be stored and handled with caution to prevent fires.

Can Mineral Oil Catch Fire Easily?

Mineral oil has a low flash point, making it susceptible to catching fire easily when exposed to an open flame or heat source.

How Does Mineral Oil Ignite?

Mineral oil can ignite when it comes into contact with a spark, flame, or high heat, leading to a potential fire hazard.

What Precautions Should I Take With Mineral Oil?

To prevent fire accidents, ensure proper ventilation, keep away from heat sources, and store mineral oil in a cool, dry place.


In conclusion, mineral oil itself is considered non-flammable but can pose a fire hazard when exposed to an open flame or high temperatures. Its low flash point is a cause for caution when handling and storing mineral oil. By following proper safety protocols and using it responsibly, mineral oil can be used effectively in various industries without compromising safety.
