Trying out new carrier oils is something I really enjoy, but what I don’t enjoy is having them go rancid before I’ve had the chance to really experience all the oil has to offer. This seems to be a common issue, especially if you’re trying to find the right oil for you skin type or its specific needs. All too often we forget that we have half a bottle of beautiful carrier oil before moving on to the next only to rediscover it later and find that it’s gone off.
It you have ever experienced the “old crayon” scent or tacky texture, you know what I mean, and it’s such a tragedy when you lose an old favorite to oxidation.
To hopefully help remedy this sad situation, I’ve gone ahead and collected as many carrier oils as I could and their shelf life so that you can keep track.
Of course, the shelf life of any given oil will largely depend on how it’s treated and stored, but if well taken care of, a carrier oil can be used to its full extent.
The Shelf Life of Carrier Oils and How to Extend it!
Before we dive into the oils, I want to first go over a few very important tips on how to extend the shelf life of carrier oils in general.
1. Store them in a cool dark place
This is one of the most important steps to follow if you want your carrier oils to stay fresh. UV rays from direct sunlight will very quickly begin to break down an oil and cause it to rancid much more quickly. Heat should also be avoided as it will speed up oxidation and turn your oils.
Store carrier oils in a cool dark cupboard to keep them away from any type of heat and sunlight. Keeping them in dark bottles is another good way to store them.
2. Store them in smaller bottles
This can be a bit tricky if you don’t have different sized bottles, but if possible, it is best to store carrier oils in the smallest bottle possible as they are used. This is because oxygen oxidizes the oil. The more air the bottle contains the faster the carrier oil can go rancid.
If you have just 2 oz left of carrier oil stored in an 8oz bottle, you may want to see about transferring it into an actual 2oz bottle to help it stay fresh longer, especially if it’s an oil you don’t tend to use often.
3. Make sure they’re capped tightly closed
If oxygen can get into the storage bottle via a loose-fitting cap, your carrier oils will go rancid more quickly.
This happens because polyunsaturated oils like avocado, chia seed, grapeseed, sesame, and safflower oil all contain carbon chains where the hydrogen atoms are absent and oxygen atoms can attach. When oxygen attaches, oxidation occurs and causes the carrier oil to go rancid.
Simply keep all caps tightly closed to prevent this from happening.
Of course, you may notice that some oils go rancid faster than others and that can be due to a number of factors like how long the polyunstaturated chain is within the oil, whether it’s considered a saturated or monosaturated oil, if it’s a fixed oil, and its antioxidant content.
4. Store them in the fridge
The best way to extend the shelf life of carrier oils is to store them in the fridge. It’s much colder and there’s no sunlight which are two major factors that contribute to rancidity.
Storing your carrier oils the fridge can extend the life of carrier oils by as much as 1 year!
5. Keep them clean
When using your carrier oils, make sure you’re not getting any water, moisture (this tends to happen when using fresh herbs during infusion), or impurities in them.
Using unwashed utensils or pouring any unused carrier oil back into its original container is a sure way to speed up rancidity.
Everything that touched the oil should be as clean and dry as possible to prevent oxidation or any kind of germs from growing in it.
As long as you control the temperature, cleanliness, light exposure, and air exposure your oils should last to the full extent of their shelf life.
Why Does This Matter?
Carrier oils, just like essential oils, each have their own benefits and properties they can lend to our recipes. If you mistreat them, they will lose their potency and usability which sort of defeats the purpose of using high-quality carrier oils, especially the fancier ones.
Even adding fresh perfectly potent essential oils to a carrier oil that has turned isn’t going to save it.. If nothing else, you will just smell like turned oil with a bit of fragance added. Not very nice if you ask me!
So, do yourself a favor and keep your carrier oils properly cared for so that you may enjoy them throughout their shelf life.
