What Is Coconut Oil Fractionated?

Fractionated coconut oil is coconut oil that has been processed to remove most of its long-chain fatty acids, leaving mainly medium-chain triglycerides (MCTs). This process changes the oil from a solid at room temperature to a clear liquid that stays liquid even when refrigerated. It is also called MCT oil or liquid coconut oil, and it is commonly used in skincare, cosmetics, and cooking.

How Is Coconut Oil Fractionated?

Regular coconut oil is about 90% saturated fat. Most of that fat is made of medium-chain triglycerides, but a portion is made of longer-chain fatty acids. Fractionation is a physical process that separates these fats by their melting points.

The oil is heated and then cooled slowly. The longer-chain fats solidify at a higher temperature, while the medium-chain fats stay liquid. The liquid is drawn off, and what remains is fractionated coconut oil. No chemicals are used in this process. It is a physical separation, similar to how cream is separated from milk.

The result is an oil that is nearly 100% medium-chain triglycerides. The most common MCTs in fractionated coconut oil are caprylic acid (C8) and capric acid (C10). These are the fats your body can absorb and use quickly for energy.

What Is the Difference Between Regular and Fractionated Coconut Oil?

The main difference is the fatty acid profile. Regular coconut oil contains a mix of medium-chain and long-chain fatty acids. Fractionated coconut oil contains only medium-chain triglycerides.

This difference changes how the oil behaves. Regular coconut oil is solid below 76°F (24°C). Fractionated coconut oil stays liquid at much lower temperatures. You can store it in the refrigerator and it will still pour easily.

The smoke point also differs. Fractionated coconut oil has a higher smoke point than regular coconut oil, which means it can be heated to higher temperatures before it starts to smoke and break down. Regular coconut oil has a smoke point around 350°F (177°C). Fractionated coconut oil is closer to 400°F (204°C).

Nutritionally, the two oils are not identical. Regular coconut oil provides a small amount of long-chain fatty acids that your body handles differently. Fractionated coconut oil is purely medium-chain, which is why athletes and people following ketogenic diets often prefer it.

What Are the Health Benefits of Fractionated Coconut Oil?

Medium-chain triglycerides are absorbed differently than other fats. Instead of being packaged into chylomicrons and traveling through the lymphatic system, MCTs go directly to the liver. There, they are quickly converted into energy. This is why MCTs are often described as a fast source of fuel.

Some research suggests that MCTs may help with weight management. Studies have found that replacing long-chain fats with MCTs can increase feelings of fullness and slightly increase calorie burning. The effect is modest, and it does not replace the need for a balanced diet and regular physical activity.

Fractionated coconut oil may also support cognitive function. The liver converts MCTs into ketones, which can cross the blood-brain barrier and serve as an alternative fuel for brain cells. Some studies in older adults with mild cognitive impairment have shown improvements in memory and processing speed. The evidence is promising but not conclusive.

For people following a ketogenic diet, fractionated coconut oil is a practical tool. It helps raise ketone levels without adding carbohydrates. Many people add it to coffee or smoothies for this purpose.

One important note: fractionated coconut oil contains no vitamins or minerals. It is pure fat. It should not replace whole foods that provide nutrients.

How Is Fractionated Coconut Oil Used in Skincare?

Fractionated coconut oil is a popular ingredient in skincare and cosmetics. Because it is liquid at room temperature, it spreads easily and absorbs quickly. It does not leave a greasy residue like regular coconut oil can.

It is often used as a carrier oil for essential oils. A carrier oil dilutes essential oils so they are safe to apply to the skin. Fractionated coconut oil works well for this because it is odorless and does not interfere with the scent of the essential oil.

As a moisturizer, fractionated coconut oil helps soften the skin by trapping moisture. It is also used in massage oils because it provides glide without staining sheets or clothing.

There is a common misconception that fractionated coconut oil can treat acne. The evidence does not support this. Coconut oil, including the fractionated form, is comedogenic, which means it can clog pores. For people prone to acne, this oil may make breakouts worse. If you have acne-prone skin, test it on a small area first or choose a non-comedogenic moisturizer instead.

Can You Cook with Fractionated Coconut Oil?

Yes, you can cook with fractionated coconut oil. Its high smoke point makes it suitable for sautéing and frying. It has a neutral flavor, so it will not change the taste of your food.

However, it is not ideal for every cooking method. Because it stays liquid at room temperature, it cannot be used as a solid fat in baking. You cannot substitute it for butter or shortening in recipes that require a solid fat.

Fractionated coconut oil is a common addition to coffee, a practice often called “bulletproof coffee.” The oil blends into the coffee and provides a quick source of energy. Some people find this helps them feel full until lunch. Others find it upsets their stomach, especially when they first start using it.

If you are new to fractionated coconut oil, start with a small amount. Medium-chain triglycerides can cause digestive discomfort, including diarrhea and cramping, when consumed in large amounts. This is especially true for people who are not used to high-fat foods.

Are There Any Risks or Side Effects?

Fractionated coconut oil is generally safe for most people when used in normal amounts. The U.S. Food and Drug Administration recognizes coconut oil as safe for use in food and cosmetics.

The most common side effect is digestive upset. Starting with too much MCT oil at once can cause nausea, diarrhea, and stomach cramps. This is because MCTs are absorbed rapidly, and the digestive system needs time to adjust.

People with liver disease should be cautious. Because MCTs are processed directly by the liver, a damaged liver may not handle them well. If you have a liver condition, talk to your doctor before adding fractionated coconut oil to your routine.

On the skin, fractionated coconut oil can cause irritation in some people. It is rare, but allergic reactions can occur. If you notice redness, itching, or a rash, stop using it.

Pregnant and breastfeeding women can use fractionated coconut oil in cooking, but there are no specific clinical guidelines for using MCT oil as a supplement during pregnancy. If you are pregnant and considering using it for health purposes, discuss it with your healthcare provider first.

What Is the Difference Between MCT Oil and Fractionated Coconut Oil?

They are essentially the same product. MCT oil is the supplement name for fractionated coconut oil. Both are made through the same fractionation process, and both contain medium-chain triglycerides.

The only difference is labeling. “MCT oil” is the term used in the supplement and sports nutrition market. “Fractionated coconut oil” is the term used in the cosmetic and skincare market. The product itself is identical.

There is one caveat. Some MCT oil products are made from a blend that includes C8 and C10, while others are made purely from C8. C8 is absorbed faster and produces more ketones per gram than C10. If you are using MCT oil specifically for ketosis, check the label to see which medium-chain triglycerides it contains.

How Should You Choose and Store Fractionated Coconut Oil?

Look for products that are labeled “100% pure” or “unrefined.” Fractionated coconut oil should not contain additives, preservatives, or other carrier oils. The ingredient list should have only one item: fractionated coconut oil (or MCT oil).

Storage is simple. Because it stays liquid at room temperature, you can keep it in your pantry or kitchen cabinet. Exposure to heat and light can degrade the oil over time, so store it in a cool, dark place. It has a long shelf life, typically two years or more when stored properly.

If the oil develops an off smell or taste, discard it. Rancid oil will have a sharp, unpleasant odor. This is rare with fractionated coconut oil because the fractionation process removes many of the compounds that oxidize, but it can still happen with improper storage.
