If you have ever been frustrated by the weight, solidity or slight scent of ordinary coconut oil, fractionated coconut oil may be a revelation. It is light, clear, odorless and always liquid. It is easy to blend and easy to store, and it has become one of the most popular carrier oils for essential oils. But it is also a product that is frequently misunderstood. What does “fractionated” actually mean? How does it differ from regular coconut oil? And how should it be used to make safe, effective blends? This article answers all of these questions.
What Is Fractionated Coconut Oil?
Regular coconut oil contains a mixture of fatty acids. The main ones are lauric acid (C12), making up about half, along with capric (C10), caprylic (C8), myristic (C14), palmitic (C16) and smaller amounts of others.
Fractionation is a process in which the oil is separated into its component parts, using heat and hydrolysis (steam) followed by distillation. The long-chain fatty acids, including most of the lauric acid, are removed. What remains is a fraction rich in medium-chain triglycerides (MCTs), primarily caprylic and capric triglycerides.
The name “fractionated” is therefore quite literal: a fraction of the original oil is retained. On cosmetic labels you may see it listed as “caprylic/capric triglyceride” or sold as “MCT oil.” You may also see the terms “liquid coconut oil” or “fractionated coconut oil (FCO).”
How It Differs From Regular Coconut Oil
It stays liquid. Regular coconut oil solidifies below about 24°C (76°F). Fractionated coconut oil remains a clear, free-flowing liquid at all normal temperatures, even in the refrigerator.
It is almost odorless and colorless. Virgin coconut oil smells distinctly of coconut. Fractionated coconut oil has very little scent, so the aroma of your essential oils remains true.
It has a lighter feel. Many people find fractionated coconut oil feels silkier and less greasy than regular coconut oil. It absorbs readily without leaving a heavy film.
It has a long shelf life. Because it is highly saturated and consists of medium-chain triglycerides, it is extremely resistant to oxidation. Depending on the source and storage, it typically lasts two years or longer.
It is less likely to stain. Fractionated coconut oil is generally less prone to leaving greasy marks on fabrics, though no oil is completely stain-free, and I would advise care with silk and light-colored clothing.
It has a different fatty acid profile. Since most of the lauric acid is removed, fractionated coconut oil lacks some of the properties associated with regular coconut oil. It is a very good carrier, but it should not be seen as identical to virgin coconut oil.
Why It Works Well With Essential Oils
There are several reasons why fractionated coconut oil is a good partner for essential oils.
Easy mixing. Essential oils dissolve readily in it, and because it is liquid at all temperatures, there is no need to melt it first.
Neutral scent. Because it has almost no aroma, it does not interfere with delicate fragrances, such as neroli, rose or ylang ylang.
Good spreadability. The oil glides well, which makes it good for massage and for application in roll-on bottles.
Stability. Stable oils protect your blend from rancidity, so your creations last longer.
Suitability for many skin types. It is generally well tolerated and less likely to block pores than regular coconut oil, though people prone to breakouts should still patch test and go carefully with facial use.
How to Dilute Essential Oils in Fractionated Coconut Oil
Dilution is the single most important safety principle in essential oil use. The amount of essential oil you should add depends on who is using it and what for.
Here are commonly used guidelines. They assume about 20 drops per ml.
| Dilution | 10 ml roll-on | 30 ml (1 fl oz) | Typical use |
|---|---|---|---|
| 0.5% | 1 drop | 3 drops | Facial use, very sensitive skin |
| 1% | 2 drops | 6 drops | Daily use, general body care |
| 2% | 4 drops | 12 drops | Massage, short-term use |
| 3% | 6 drops | 18 drops | Short-term, localized use |
For children, older adults and people with sensitive skin, use lower dilutions (0.25–1%) and choose gentle oils. For pregnant women, a maximum of 1% is a sensible limit, with oils chosen carefully.
Please bear in mind that these figures are only guidance. Some essential oils, such as ylang ylang, cinnamon leaf, clove and peppermint, have lower recommended maximums, and certain oils, such as cold-pressed citrus, are phototoxic. Always check the specific safety guidance for the oils you use.
Practical Uses
Roll-On Blends
This is probably the most popular use. A glass roll-on bottle is ideal.
Simple relaxation roll-on (10 ml, about 2%):
- 2 drops lavender
- 1 drop sweet orange
- 1 drop Roman chamomile
- Fill with fractionated coconut oil
Roll on the wrists or the back of the neck, avoiding the face and eyes.
Massage Oil
Fractionated coconut oil offers a good glide for massage. It is thin, so it may absorb more quickly than heavier oils, which suits some therapists and not others. If you want more slip time, blend it with a little sweet almond or jojoba oil.
Muscle-easing massage oil (30 ml, about 2%):
- 5 drops rosemary
- 4 drops lavender
- 3 drops sweet marjoram
Body Oil After Bathing
Apply to damp skin after a shower, when the oil helps lock in moisture. Use 1% for everyday body oil.
Bath Oil
Oils do not dissolve in water, and essential oils can float on the surface in concentrated form, coming into direct contact with the skin. Never add essential oils directly to bathwater. Instead, dilute them first in fractionated coconut oil (a tablespoon is usually enough), or use a proper dispersant, and add this mixture to the bath. Take care, because the oil will make the bath floor slippery.
Hair and Scalp Treatments
A very light blend can be massaged into the scalp, using 0.5–1% and avoiding the eyes. Rosemary and lavender are common choices. Do not use strongly irritant oils on the scalp.
Perfume Oils
The neutral scent and stability of fractionated coconut oil make it a good choice for natural perfume roll-ons. Use higher concentrations of 5–10% only for perfume applied to small areas of the skin, and only with oils that are safe at that level. Where in doubt, keep to lower percentages.
Tips for Buying and Storing
Read the label. Look for “fractionated coconut oil,” “caprylic/capric triglyceride” or “MCT oil.” Choose a cosmetic-grade product from a reputable supplier. Note that some products sold for cooking are not suitable for cosmetic use, and cosmetic-grade oils should not be eaten.
Choose glass. Store your blends in dark glass bottles. Medium-chain triglycerides can interact with some plastics over time, so glass is the safest choice for roll-ons and storage.
Keep it cool and dark. Even though fractionated coconut oil is very stable, essential oils are not. Store your finished blends away from heat and light, and label each bottle with the ingredients and the date.
Use a clean dropper. Do not let contaminants, water or fingers get into the bottle.
Points to Watch
Coconut allergy: it is rare, but people with a known allergy to coconut should avoid coconut-derived products, including fractionated coconut oil.
Patch testing: apply a small amount of your blend to the inner forearm and wait 24 hours before wider use.
Not for ingestion: do not take essential oil blends by mouth, however they are diluted.
Sun exposure: if your blend contains a phototoxic essential oil, such as cold-pressed lemon, lime, grapefruit or bergamot, follow the maximum dilution for that oil and avoid sun exposure on the skin.
Pets and children: keep all blends out of reach.
Final Thoughts
Fractionated coconut oil is an excellent, practical carrier for essential oils. It is light, stable, easy to use and gentle on most skin. It is not identical to virgin coconut oil, and it does not need to be. It has its own strengths, and for roll-ons, massage blends and perfume oils, it is hard to beat. Whichever blend you make, remember the basics: dilute properly, patch test, store carefully and respect the strength of the essential oils you are using. If you do, fractionated coconut oil will give you a reliable, pleasant foundation for a wide range of aromatherapy blends.
