MCT Oil vs Fractionated Coconut Oil: What's the Real Difference?

If you've spent any time exploring essential oils and aromatherapy, you've likely encountered both MCT oil and fractionated coconut oil. These two terms are often used interchangeably, leaving many people wondering: are they the same thing, or is there a meaningful difference between MCT oil vs fractionated coconut oil?

The confusion is understandable. Both are lightweight, non-greasy carrier oils derived from coconuts. Both remain liquid at room temperature and have an incredibly long shelf life. They're both popular choices for diluting essential oils, creating massage blends, and formulating skincare products. But here's the thing: while they share many similarities, they're not exactly identical twins—they're more like close cousins.

In this comprehensive guide, we'll unravel the mystery surrounding these two popular carrier oils. You'll learn what each one actually is, how they're made, their unique properties, and most importantly, which one is the best choice for your specific aromatherapy and wellness needs. Whether you're a seasoned essential oil enthusiast or just beginning your aromatherapy journey, understanding these differences will help you make more informed decisions for your practice.

What Is Fractionated Coconut Oil?

Fractionated coconut oil is created through a process called fractionation, which separates the different types of fatty acids found in regular coconut oil. To understand this, let's start with virgin coconut oil—the solid white oil you might use for cooking.

Regular coconut oil contains various fatty acids with different chain lengths. The longer-chain fatty acids (like lauric acid) are what cause coconut oil to solidify at temperatures below 76°F (24°C). During fractionation, these long-chain fatty acids are removed through a heating and cooling process, leaving behind only the medium-chain triglycerides (MCTs).

The result? A lightweight, completely liquid oil that stays fluid even in cold temperatures. Fractionated coconut oil is:

• 100% derived from coconuts through mechanical processing
• Composed primarily of caprylic acid (C8) and capric acid (C10) fatty acids
• Completely stable with a shelf life of several years
• Colorless, odorless, and non-staining
• Highly emollient without leaving a greasy residue

In the aromatherapy world, fractionated coconut oil has become the gold standard carrier oil. It absorbs quickly into the skin, doesn't interfere with the aromatic profile of essential oils, and won't go rancid even after extended storage.

What Is MCT Oil?

MCT stands for Medium-Chain Triglycerides—fatty acids with a chain length of 6 to 12 carbon atoms. MCT oil is a concentrated source of these specific fatty acids, and while it's most commonly derived from coconut oil, it can also be sourced from palm kernel oil or created through a combination of sources.

Here's where things get interesting: not all MCT oils are created equal. The term "MCT oil" is actually an umbrella category that can include different ratios of four types of medium-chain fatty acids:

• Caproic acid (C6): The shortest chain, rarely included due to taste issues
• Caprylic acid (C8): Highly valued for quick absorption and energy
• Capric acid (C10): Slightly longer chain, still easily metabolized
• Lauric acid (C12): Technically an MCT but behaves more like a long-chain fatty acid

The composition of MCT oil can vary significantly depending on the manufacturer and intended use. Some MCT oils contain only C8 and C10 (considered the "true" MCTs), while others include C12 (lauric acid), which is more abundant and less expensive but doesn't offer the same rapid absorption benefits.

MCT oil gained popularity in the health and wellness community for its potential cognitive and energy-boosting properties, particularly among those following ketogenic diets. However, it's also increasingly used as a carrier oil in aromatherapy applications.

The Key Differences Between MCT Oil and Fractionated Coconut Oil

Now that we understand what each oil is, let's explore the nuances that set MCT oil vs fractionated coconut oil apart:

Source and Processing Fractionated coconut oil is always 100% derived from coconuts through a specific fractionation process. MCT oil, while often coconut-derived, may come from palm kernel oil or a blend of sources. This distinction matters for those with specific ethical concerns about palm oil production or those seeking pure coconut-derived products.

Fatty Acid Composition Fractionated coconut oil typically contains a natural ratio of C8 and C10 fatty acids as they occur after fractionation—usually around 50-60% caprylic acid (C8) and 40-50% capric acid (C10). MCT oil composition can be manipulated to contain specific ratios, with some products offering pure C8 or higher concentrations of particular fatty acids.

Intended Use Fractionated coconut oil is specifically formulated and marketed for topical applications in aromatherapy, massage, and skincare. MCT oil is often positioned as a dietary supplement or cooking oil, though it can certainly be used topically as well.

Quality Standards Fractionated coconut oil sold for aromatherapy purposes typically meets cosmetic-grade standards and is tested for topical safety. MCT oil marketed for consumption follows food-grade standards. While both are safe for skin application, fractionated coconut oil is specifically refined with topical use in mind.

Price Point Generally, fractionated coconut oil tends to be slightly more affordable than specialized MCT oils, particularly those with higher concentrations of C8. However, prices vary widely depending on brand, quality, and sourcing.

Which One Should You Choose for Aromatherapy?

When it comes to diluting essential oils and creating aromatherapy blends, both MCT oil and fractionated coconut oil can serve you well. However, here are some guidelines to help you choose:

Choose Fractionated Coconut Oil If:

• You're specifically looking for a carrier oil designed for topical aromatherapy use
• You want a product with established standards in the essential oil community
• You prefer knowing your oil is 100% coconut-derived
• You're creating massage oils, roll-on blends, or skincare formulations
• You want the most cost-effective option for regular aromatherapy practice

Choose MCT Oil If:

• You want a dual-purpose oil for both topical and internal use
• You prefer a specific fatty acid ratio (like pure C8 for faster absorption)
• You're already using MCT oil for dietary purposes and want to minimize products
• You're creating products where the specific fatty acid profile matters

For most aromatherapy applications, fractionated coconut oil is the ideal choice. It's specifically formulated for topical use, widely available from reputable essential oil suppliers, and has a proven track record in the aromatherapy community.

Benefits of Using These Carrier Oils with Essential Oils

Whether you choose MCT oil or fractionated coconut oil, both offer significant advantages as carrier oils:

Excellent Absorption Both oils penetrate the skin quickly without leaving a heavy, greasy residue. This makes them perfect for massage oils and daily skincare applications where you don't want to feel oily all day.

Neutral Aroma Unlike some carrier oils that have distinct scents (like olive oil or sesame oil), these oils are virtually odorless. This allows the aromatic properties of your essential oils to shine through without interference.

Extended Shelf Life The medium-chain fatty acids in both oils are highly stable and resistant to oxidation. You can expect a shelf life of 2-3 years or more when stored properly, making them economical choices for your aromatherapy practice.

Non-Comedogenic Properties Both oils have a low comedogenic rating, meaning they're unlikely to clog pores. This makes them suitable for facial applications and for those with acne-prone skin.

Versatile Applications From creating custom perfume oils to making therapeutic massage blends, these carrier oils work beautifully in virtually any aromatherapy application. They're also excellent for diluting essential oils for children, as they're gentle and well-tolerated.

How to Use MCT Oil and Fractionated Coconut Oil Safely

When working with either oil as a carrier for essential oils, follow these best practices:

Proper Dilution Ratios

• Adults: 2-3% dilution (12-18 drops of essential oil per ounce of carrier oil)
• Children (6-12 years): 1% dilution (6 drops per ounce)
• Children (2-6 years): 0.5% dilution (3 drops per ounce)
• Facial applications: 1% dilution or less
• Sensitive skin: Start with 1% and adjust as needed

Storage Recommendations Store your carrier oil in a cool, dark place away from direct sunlight. While these oils are stable, exposure to heat and light can still degrade them over time. Use amber or cobalt blue glass bottles for long-term storage of blended products.

Patch Testing Even though both oils are generally well-tolerated, always perform a patch test when trying a new essential oil blend. Apply a small amount to your inner forearm and wait 24 hours to check for any adverse reactions.

Quality Matters Choose organic, hexane-free oils from reputable suppliers. For aromatherapy purposes, look for fractionated coconut oil or MCT oil that's specifically labeled for topical use and meets cosmetic-grade standards.
