How To Read A Dilution Chart

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. 

The Diluent

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:

  • Nuts

  • Seeds

  • Kernels

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

Dilution Percentages

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 – 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).

This was the best article I have found on diluting oils. I’ve always had issues with diluting. This was simple enough to understand. Thank you.

Hi, I’m looking into making up a salve/balm…the recipe I have makes up 8oz of product, consisting of carrier oil, beeswax, shea butter and essential oils. I’ll be using three (vetiver, kunzea & yarrow)…the recipe recommends half a teaspoon of combined E.O.‘s or less total…however, I don’t know how to do it so I get the right dilution. How do I dilute the oils…before or after the blending?

Hi Deshawn! A 4% dilution in 2 oz of carrier oil = 48 drops of essential oil and a 5% dilution in 2 oz of carrier oil = 60 drops of essential oil.

Hi. How many drops of tea tree oil can I put in a 2 fl oz (56 ML) Bottle of jojoba oil to get a 4 to 5 percent dilution for a hair treatment?

Hi Poornima! If you are looking to make a 3% dilution, then yes, you can always combine 18 drops of essential oil with 2 tablespoons of carrier oil (not teaspoons). Here’s a helpful dilution calculator as well:

Great article, Bella! I have a bottle of 3% dilution of EO in jojoba. If I’m using it to make a product, lets say a roll-on, how would I calculate the total EO? Can I always assume it’ll be 18 drops (2 tsps) for every EO? How do I calculate the jojoba (minus the EO) for any recipe?

I hope this question makes sense! Thanks so much!

Since the specific gravity of many EO’s is very different than that of water (water=20drop/ml), many EO have SG of 30drop/ml or higher. These dilution charts are a great “Guide” but one must respect the chemical one is working with. It might be helpful to note the SG for each EO in your description so precise calculations could be made.

Hi Shay! It depends on the topical application. A 1% dilution is recommended for facial use, bath use, young children, and pregnant women. A 2-3% dilution is recommended for general topical use. A higher dilution may be necessary for short-term injuries and pain, spot treatment, as well as perfume.


July 27, 2023 at 8:31 am

how do you determine what delusion percentage you want to use? I’m confused about that.

Hi Joan! For a 5% dilution ratio, we suggest 30 drops of essential oil (total) per 1 oz carrier oil.

I am mixing four essential oils for hair growth. Lavender, rosemary, peppermint and cedar wood. If I want a 5% dilution is it 5% for each essential oil, or 5% total of all the essential oils with the carrier oil?

Hi Denise! Different issues call for different doses. Likewise, different individuals (children, adults, the elderly, etc.) require different doses. You can learn more about what dilution rate to choose for your specific need and age range here:

Hi Sybil! Some essential oils have specific recommended maximum dilutions rates. You can find those oils and their dilution rates here:

Do the ratio of the essential oil drops to carrier oil remains the same for all types of essential oil or it varies by essential oil? example would you dilute Frankincense and Peppermint Essential Oil according to the chart?


June 1, 2021 at 8:33 am

I’ve read some of your other articles re: recommended dilutions of single oils, but I get confused with blends. I just bought your Shea nut carrier oil with the Skin Love synergy blend. Is there a max dilution you recommend with that blend?

Hi Jim! Store-bought carrier oils like Avocado and Walnut are suitable diluents for essential oils. Dilution is also unnecessary if using essential oils in a water diffuser.

This is so simply explained and gives you a pattern to make any dilution. It is 1 drop of essential oil for each 5 ml of carrier oil for a 1% solution.
A. If you have more carrier oil, devise the amount by 5 and that’s how many drops of essential oil to add.
B. If you want a higher concentration (greater percentage), add 1 additional drop of essential oil for each percent increase in stronger dilutions than 1%.
C. When using a greater amount of carrier oil and greater (stronger) dilutions, combine the aspects of A. and B.

Thank you
