The Difference: FCO vs. Virgin Coconut Oil
Before exploring the heating process, it is essential to understand what fractionated coconut oil (FCO) is and how it differs from its virgin counterpart. While virgin coconut oil contains a full spectrum of fatty acids, including lauric acid (C12) which causes it to solidify at room temperature, FCO is created by heating and cooling the oil to isolate the medium-chain triglycerides (MCTs), primarily capric (C10) and caprylic (C8) acid. This process removes the long-chain fatty acids, leaving a liquid that is colorless, odorless, and highly stable.
Heating FCO for Cosmetic and Aromatherapy Use
For cosmetic and aromatherapy applications, the primary goal is gentle warming, not cooking. When used as a carrier oil for essential oils, FCO only needs to be warm enough to blend evenly, not heated to a high temperature. Exposing essential oils to excessive heat can degrade their delicate aromatic compounds and therapeutic properties.
Safe Methods for Warming FCO
- Warm Water Bath: Place the FCO container in a bowl of warm water and let the gentle heat transfer through the glass. This is the safest method for achieving a warm, smooth consistency.
- Body Heat: For small amounts, simply cupping the bottle in your hands is enough to transfer body heat and warm the oil.
- Lizard Warmer (for larger quantities): For those using large volumes, such as in a small-scale manufacturing or spa setting, dedicated oil warmers or low-temperature heating devices can provide consistent, controlled heat without risk of degradation.
Culinary Considerations: FCO, MCT Oil, and Cooking
This is where significant confusion arises, as the terms 'fractionated coconut oil' and 'MCT oil' are often used interchangeably but are not always the same. FCO intended for cosmetics may not be produced in food-safe facilities. Conversely, food-grade MCT oil is derived through the fractionation process but is specifically manufactured for safe human consumption.
Can I cook with food-grade MCT oil?
Yes, but with caution. Food-grade MCT oil has a moderate smoke point of around 320°F (160°C), which is lower than refined coconut oil. This makes it suitable for low to medium-heat applications, but not for high-heat frying or searing. Cooking with MCT oil offers benefits like a neutral taste and a quick energy source, but its temperature limitations are key.
Dangers of High-Heat Cooking
Heating any oil beyond its smoke point causes it to break down, releasing harmful free radicals and creating ignitable gases. This not only affects the quality and flavor of your food but can also pose health risks. For high-temperature cooking, choose oils with a higher smoke point, such as avocado oil.
FCO vs. Virgin Coconut Oil Comparison Table
| Feature | Fractionated Coconut Oil (FCO / MCT Oil) | Virgin Coconut Oil (VCO) |
|---|---|---|
| State at Room Temp. | Liquid | Solid (below 76°F / 24°C) |
| Composition | Medium-chain triglycerides (MCTs) like C8 and C10 | Full spectrum of fatty acids, including lauric acid |
| Heating Stability | Moderate heat for food-grade MCT oil (approx. 320°F smoke point) | Lower smoke point for unrefined versions (approx. 350°F / 177°C) |
| Primary Uses | Carrier oil, cosmetics, massage oil, nutritional supplement | Baking, sautéing, moisturizer (requires melting) |
| Odor & Flavor | Odorless, flavorless | Distinct coconut aroma and flavor |
| Consumption Safety | Food-grade MCT is safe; cosmetic-grade is not | Safe for consumption |
The Final Verdict on Heating Fractionated Coconut Oil
Yes, you can heat fractionated coconut oil, but the context and application are everything. For personal care, gentle warming is the best practice to maintain the oil's integrity and the delicate properties of any added ingredients. When it comes to cooking, only use a food-grade product, such as MCT oil, and keep the heat moderate to stay below its smoke point. For high-temperature culinary methods, opt for an oil with a higher smoke point.
Ultimately, understanding the properties of your specific product—whether for cosmetic or culinary purposes—is the most important step for safe and effective use. Always read the label and follow the manufacturer's recommendations to ensure you are heating the oil appropriately for your intended application.

Conclusion
Fractionated coconut oil is a versatile liquid that can be heated safely for a variety of purposes, provided you understand its limitations. Gentle heat is ideal for personal care applications like aromatherapy and massage, while food-grade MCT oil can be used for medium-temperature cooking. The key is to avoid high heat and always verify the product's grade to ensure its suitability for your needs. By following these guidelines, you can safely leverage the unique benefits of this refined and stable oil.
