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 rehash this crucial topic until everyone feels comfortable diluting.
Recently we received a few questions on how to read the dilution charts we offer. What use is a dilution chart if you don’t know how to read it? Let’s break it down.
You will typically see essential oils diluted in one ounce of carrier oil. As in the image above, a 1% dilution rate is 6 drops of essential oil per one ounce of carrier oil. To achieve a 2% dilution rate, you would multiply the number of drops of essential oil by two, but keep one ounce of carrier oil the same. If you were to multiply the number of ounces of carrier oil by two, as well as 6 drops of essential oil, it would still equal to a 1% dilution rate.
This works if you want to use more carrier oil, but be sure to multiply the number of drops of essential oil according to the dilution rate you want to achieve. For example, say you have 4 ounces of carrier oil but want to achieve a 3% dilution rate. Because the above 3% dilution rate is measured per one ounce of carrier oil, and you are using four ounces of carrier oil, simply multiply 18 drops by four. As you will find, 72 drops of essential oil in 4 ounces of carrier oil is a 3% dilution rate.
You may also come across dilution rates that are measured in less than an ounce of carrier oil, such as in our roll-on dilution charts which we measure in 10 ml or 2 tsp of carrier oil. 10 ml is ⅓ of an ounce, so you would then divide the number of drops of essential oil from this dilution chart by three to achieve your desired dilution in 10 ml of carrier oil. When you have a lower amount of carrier oil, you will also reduce the amount of essential oils you are using through division such as we did above. We have made it easy by creating this roll-on dilution chart.
Yes, essential oil dilution does require a little math, but with practice you can figure out your own dilution amounts in no time. In the meantime, these dilution charts are a helpful tool. Happy diluting!
