Does Melting Coconut Oil Make it Bad?

Coconut oil is an extremely versatile and popular ingredient that is used in various dishes and as a skincare/haircare product. While there are various ways to use it, many people wonder about the change that occurs when the oil is subjected to heat. So, if you’ve ever wondered if melting coconut oil can make it go bad, you’ve come to the right place.

The Composition of Coconut Oil

Before we dive into the details of whether melting coconut oil can affect its quality, it’s crucial to understand the composition of coconut oil. Unlike most other oils, coconut oil is solid at room temperature and has a melting point of around 76°F (24°C).

Coconut oil is a combination of fatty acids like lauric, caprylic, and capric acids. These fatty acids make up around 96% of the oil, while the remaining 4% is water, vitamins, and minerals.

The fatty acids present in the oil are responsible for its beneficial properties, such as its antimicrobial, antioxidant, and anti-inflammatory effects.

What Happens When Coconut Oil Melts?

As mentioned earlier, coconut oil is solid at room temperature, but once the temperature exceeds 76°F (24°C), it begins to melt and turn into a liquid form. However, this doesn’t mean that the oil has gone bad or has lost its nutritional value.

Melting coconut oil is simply a physical change, and it does not affect the chemical properties or composition of the oil. Unlike other oils, such as olive oil, coconut oil is very resistant to heat, and it can withstand high temperatures without undergoing any significant change or oxidation.

Does Melting Coconut Oil Reduce Its Benefits?

Many people use coconut oil for its numerous health benefits, such as aiding in digestion, improving brain function, and supporting weight loss. However, some worry that melting the oil could reduce or even negate its beneficial effects.

Fortunately, this is not the case. Melting coconut oil does not reduce its nutritional value. The beneficial fatty acids like lauric acid, caprylic acid, and capric acid remain intact even after the oil melts. Therefore, melted coconut oil is equally as nutritious as solid coconut oil.

What Happens When Coconut Oil Goes Rancid?

Coconut oil has a long shelf life and can typically last for up to two years without going rancid. Rancidity occurs when the oil is oxidized due to exposure to heat, light, or air.

If coconut oil goes rancid, it will develop an unpleasant odor and taste. You’ll also notice a change in the color and consistency of the oil. Rancid coconut oil can be harmful to your health and should be disposed of immediately.

Can Melting Coconut Oil Cause It to Go Rancid?

No, melting coconut oil does not cause it to go rancid. The oxidation process that leads to rancidity occurs when the oil is exposed to air, heat, or light. While melting coconut oil may expose it to heat, the oil itself is still sealed and not exposed to air or light. Therefore, it does not speed up the oxidation process or cause the oil to go rancid.

Should You Melt Coconut Oil Before Using It?

The answer to this question mostly depends on why you are using coconut oil in the first place. If you’re using the oil for cooking or baking, you may need to melt it to mix it with the other ingredients.

On the other hand, if you’re just using the oil as a moisturizer or hair mask, there’s no need to melt it. You can apply the solid oil directly to your skin or hair, and it will gradually melt as it comes in contact with your body heat.

Tips for Storing Coconut Oil

To ensure that your coconut oil lasts as long as possible and retains its beneficial properties, it’s crucial to store it correctly. Here are some tips:

  • Store the oil in a cool, dry place away from sunlight
  • Keep it in an airtight container to prevent oxidation
  • Avoid transferring the oil between containers as it can expose it to air and contaminants
  • If possible, buy small quantities of oil that will be used within a shorter period


Melting coconut oil does not make it go bad or affect its nutritional value. The oil is very stable, and its composition remains the same even after it melts. However, it’s essential to store the oil correctly to prevent it from going rancid and maintain its beneficial properties.
