    1. You can’t. You would just need to increase the amount of carrier you use. There are a lot of people who recommend that a young baby only use essential oils at a dilution of 0.2% max. This chart will show you that you will need to make a large batch to get that dilution.

  1. I want to make an eczema cream using the anti eczema synergy. I am thinking 2oz of coconut oil and 2 oz of Shea butter. How many drops of anti eczema synergy? My son is 8 who it will be for.w1

  2. I purchased your calm the child formula. What ratio.of dilution should I use for my 3 yr old. What about my 11 year old? Thanks,

  3. I use my oils straight from the bottles and usually difuse I drop oil 1 drop carrier.
    Is there a chart for that? For 1 drop at the time? Not mls.

    1. Proper dilution is always a must! You can find our dilution guidelines by typing “dilution chart” into the search box on the home page of the blog! Thanks!!

  4. What % of dilution would you use in a rollerball with with your headache relief synergy oil blend? I started with 2%, should I increase?

  5. It seems to me that this chart is flawed. If there are 20 drops in a ml (as I’ve always known) and I want to make a 1% dilution, I should add 2 drops EO to 10 ml (or 200 drops) carrier oil, NOT 3 drops. Three drops would make a 3% dilution, wouldn’t it?

    1. This chart comes directly from Robert Tisserand’s book, Essential Oil Safety. Drops can range anywhere from 20-40 drops in a ml depending on the size of the drop so for this chart, Mr. Tisserand took the average based it on 30 drops in a ml.

  6. After mixing “larger” batch of EO and carrier oil, how should I store it for future uses? Can the mixture be used (and come through) the spray bottles PT sells? Or should I get the glass jars?
    Thinking mostly of the Silky Soft blend for my 5yo daughter. Mixed with grapeseed oil last night and used for the first time. Thinking it would be easier to make a larger amount and have ready to go after her shower. Thanks!!

    1. Once combined with a carrier, storing in a glass bottle is the best way. Keeping a cool, dark place when not in use & it will last as long as the carrier it is mixed into.

  7. Do you have anything for dogs? I have a dog who is 8 years old and has chronic yeast infections that are getting worse and closer together. Nothing seems to help.

  8. Is it ok to use virgin coconut oil to dilute (instead of the fractionated kind)? I’m asking since I already have that at home and wondering if I can avoid buying something additional. Thanks!

  9. Might you have a chart of how much dilution is necessary for each oil? For example, considering buying cypress but don’t know how much it needs to be diluted.

    1. We do have maximum recommendations for those oils that carry cautions. You can find that on our website under the description of each particular oil! 😉

  10. I ordered the Sleep-Aid and it says to dilute to 3%. According to this chart I would add 27 drops to 2 tablespoons of carrier oil. Is that correct? It seems like that is a lot of oil to add to the carrier oil.

  11. Do you use this dilution chart when you are making a spray? I want to make a bug spray with citronella and witch hazel for my one year old.

    1. We tend to recommend beginning with a 2% dilution for most purposes. 5% would be used in the case of an acute injury or use only a few times. For longer term use – keep the dilution lower (about 2%). For use on the face, 1% is best.

  12. If I am wanting to make a 10ml roller bottle with more than one oil at 4% of one oil and 10% of another will I add the EO #1 @ 4% of 12 drops and oil #2 at 10% of 30 drops and fill the remaining of the bottle with carrier oil? I am asking because I had a roller bottle I was making with 6 oils and the 6 oils was a considerable amount and only 2/3 of the bottle was left not allowing a full 10ml of carrier oil. Would it be better to just consider the conversion as a 5ml bottle and add 5ml of carrier oil on top?

    1. We love epsom salt mixed with any oils that you’d like or would be refreshing for you (peppermint on my feet is a personal favorite!)

    1. Diffusers vary so you would want to check the interest with recommendations for your particular diffuser.

    1. Hi Stephanie! If you purchased the undiluted set then they do need to be diluted. Dilution percentages range for each oil or blend,and you can find that information on the bottle or on our website.

  13. How do I dilute a carrier oil with 2 or more essential oils? Does the total EO percentage have to add to the recommended percentage or can each EO have the recommended percentage?

    1. Hi Lavette! You will want to make a blend with the essential oils and then dilute the blend in a carrier to the recommended percentage. For more specific information please email [email protected]

  14. I’m new to essential oils and also confused with adding more than one oil. So my question is and sorry if it’s stupid , but the dilution amount is per (each oil if adding more than one oil) your adding to that amount???OR the total amount of essential oils no matter how many different ones you want to add to carrier oil to equip that number for correct dilution???? Again sorry if it’s a stupid question I’m just extremely new to essential oils and don’t want to harm my little ones.

    1. Missy this is a very common question. It is the total number of drops no matter how many essential oils you are using. I like to make a master blend in a separate bottle and then use the number of drops necessary for the dilution percentage I want.

    1. Emma, 3 drops in a 10 ml is 1% and 5 drops would be approximately 1.75%. 5 drops in a 15 ml is just over 1%, and 2 drops in a 5 ml is !.5%. I hope this is helpful.

    1. There are many helpful essential oils for discomfort. It depends on the issue. If it’s minor damage and no open sores then our synergy Sore No More, or some singles like Geranium, Helichrysum, Black Pepper or Frankincense…

  15. If I’m making a rollerball blend and diluting to 2% with a 10ml container, do I add the 2% dilution of the 3 scents I am adding or is it 2% total and I have to split up the three scents within that amount? Thanks!

    1. Hi Kimberly! It is the total of the 3 oils. I usually make up a master blend of the oils I want to use, and then dilute that to 2%.

  16. I bought your kid safe Germ Destroyer which says to dilute to 1-3% for topical application. So if I want to make a 10 ml roller bottle, at 2%, I would add 6 drops of the Germ Destroyer and then fill the rest of the roller bottle with carrier oil, correct? (I had initially pulled up several different dilution charts elsewhere that said 2% is 4 drops.) Also, I would like to use the Germ Destroyer on a regular basis over winter to ward off sickness, so is dilutiing to 2% a good choice for that?

    1. We recommend a 2-3% dilution when using Let It Go topically. We hope you love this synergy as much as we do Lori!

  17. I’m a little confused. I have a 10ml toll-on that’s I want to use for peppermint oil. One chart says for 2% dilution I should use 6 drops for 2 tsp. BUT the other chart says to use 6 drops for 10ml (which is much more than 2 tsp). So how many drops should be used for 10ml of carrier oil?

    1. Hi Anika, thank so much for reaching out! The good news is 10 mls of carrier oil is equal to roughly 2 tsps of carrier oil. A 2% dilution is 6 drops of essential oil to 10 mls (or two teaspoons) of carrier. I hope this helps!

  18. For example you want to make a 3% dilution blend of different essential oils in 1 bottle, do you put 9 drops of the different essential oils each or it has to be just 9 drops total regardless of how many kinds of essential oils thay you put in the blend?

  19. This is SO helpful!!! I just got a bunch of EO’s and will be diluting them this week so will use this a lot. Perfect!!!
