How To Read A Dilution Chart
Using undiluted essential oils frequently can be a one-way ticket to sensitized, irritated skin. Diluting not only saves your skin, but also saves you money and is a good practice to learn.
Though our aromatherapists have discussed how to dilute and even created a nifty dilution chart for oils and roll-ons, we at EG feel it is important to break down the dilution chart until everyone feels comfortable diluting. After all, what use is a dilution chart if you don’t know how to read it? Continue on to learn more.
When diluting, the first thing you’re going to need is a carrier oil. A carrier oil, or base oil, is a vegetable oil commonly derived from the following plant parts:
Examples of carrier oils include:
Carrier oils are made up of fatty acids such as oleic and linoleic acids, whereas essential oils are a much more complex combination of volatile components. Fatty acids are skin-loving and combine with essential oils to make them safe as well. When used on their own, essential oils can cause skin irritation and sensitization. Furthermore, only a little essential oil is needed to make an effective topical application, thus diluting is necessary.
Now that you know why it’s necessary to dilute essential oils, let’s uncover dilution percentages.
You’ll notice that we often recommend diluting your essential oils in one ounce of carrier oil. One ounce is also equal to 30 ml or 2 tablespoons. On a dilution chart, the amount of carrier oil you dilute in doesn’t change – it will always be the same amount.
What numbers do change on a dilution chart? The percentage of essential oil and the amount of essential oil.
Now let’s look at the dilution chart. The above example shows that a 1% dilution in one ounce of carrier oil equals to 6 drops of essential oil. This means that 6 drops of essential oil makes up 1% of the total essential oil in your final concentration and that the carrier oil makes up 99% of the final concentration.
But what if you want a blend with more essential oil in it, for example, a 3% dilution? In this case, you would keep the amount of carrier oil the same, one ounce, and multiply the 6 drops of essential oil that makes a 1% dilution by 3. Therefore a 3% dilution equals to 18 drops of essential oil combined with one ounce of carrier oil. In a 3% dilution, your essential oil makes up 3% of the blend and the carrier oil makes up 97%.
Let’s break this down further. To increase your essential oil dilution, you’ll always keep the carrier oil amount consistent and multiply the amount of essential oil drops that makeup a 1% dilution by the dilution ratio you desire. Using our dilution chart as an example, to increase your dilution concentration, the one ounce of carrier oil will remain the same and you’ll multiply the 6 drops of essential oil that makeup a 1% dilution rate in one ounce of carrier oil by your desired percentage. In the example above, we multiplied 6 drops by 3, meaning 18 drops of essential oil are needed to achieve a 3% dilution in one ounce of carrier oil.
Scaling Up And Down
What if you’re making a large, stock blend and want to use 4 ounces of carrier oil, or you’re making a blend in a 10 ml roll-on? In this case, you’ll need to make a few adjustments.
Let’s use our dilution chart as an example for scaling up to achieve a 1% dilution in 4 ounces of carrier oil. Because our chart is based on dilutions containing one ounce of carrier oil, multiply each number in our chart by 4. A 1% dilution in 4 ounces of carrier oil now equals to 24 drops of essential oil (6 multiplied by 4). And further, a 3% dilution in 4 ounces of carrier oil now equals to 72 drops of essential oil (18 multiplied by 4).
What about scaling down to a 10 ml roll-on? Again, because our chart is based on dilutions containing one ounce or 30 ml of carrier oil, divide each number in our chart by 3 – because 30 ml divided by 3 equals 10 ml. A 1% dilution in 10 ml of carrier oil now equals to 2 drops of essential oil (6 divided by 3) and a 3% dilution in 10 ml of carrier oil now equals to 6 drops of essential oil (18 divided by 3).
