Dreaded Dilutions... percentage, weight or drop!!!



Robert Tisserand is a real master of Aromatherapy – he’s been in this field for decades and I learned about him way back at the turn of the new millennium. To me Robert Tisserand is like the modern father of Aromatherapy and I’ve enjoy his teachings. I also love the work of Julia Lawless and she offers a broader view of Aromatherapy but still another modern master of Aromatherapy.


There are many wonderful teachers who aided my own personal learning, growth and development in and around Aromatherapy and here I want to focus upon the dilution of essential oils.

Both Robert and Julia provide dilutions with a different perspective; I prefer Robert Tisserands approach but Julia offers an equally valuable approach too so I share both so you can choose which method to follow. This applies to the dilution of essential oils with base/vegetable oil which becomes a carrier medium when essential oils are added to it.

Robert Tisserand

Base oil = 10ml Add 1 drop essential oil and this is equal to 0.5% dilution

Add 3 drops essential oil and this is equal to 1% dilution

Add 6 drops essential oil and this is equal to 2% dilution

Add 9 drops essential oil and this is equal to 3% dilution

Add 15 drops essential oil and this is equal to 5% dilution

Base oil = 20ml simply double up the above amounts of essential oil drops.

Julia Lawless

Base oil = 5ml/1teaspon Add 1 drop essential oil and this is equal to 0.5% - 1% dilution

Base oil = 15ml/1tablespoon Add 1 -3 drop essential oil and this is equivalent to 0.5% - 1% dilution

Base oil = 1floz/25ml Add 3 – 5 drops essential oil and this is equivalent to 0.5 – 1 % dilution

Base oil = 2floz/50ml Add 5 – 10 drops essential oil and this is equivalent to 0.5% - 1% dilution

Base oil = 3½floz/100ml Add 10- 20 drops essential oil and this is equivalent to 0.5% - 1% dilution


A quick note about babies, infants and children;

It’s advised not to apply essential oils in any form of dilution to this group of people. Diffusion is the safest method and this can be achieved with a drop of essential oil on a tissue placed in their room, or through an electric diffuser which will aromatise the area with a fine mist. Another method is to apply diluted essential oil onto the parent maybe the shoulder and hold baby near the area so they can have a few breaths of inhalation whilst having a loving cuddle from mum or dad.




I’ll be making some more videos about dilutions with butters, waxes and gels to demonstrate in action the process but a link to a conversion site is shared to help you through is shared below, remember to shout out if you have any questions or would like more information about something and post a picture
