Essential Calculation

Essential Calculation

You love essential oils, and you got hooked into aromatherapy – but nobody told you there will be math. And looking at all the ratios, percentages, milliliters, ounces, drops, maximum dilutions and charts can seem daunting. But it doesn’t have to be! Join Hana Tisserand as she guides you through calculations and conversions with ease, giving you simple tools and making sure you get it, so you will never again have to ask: “How many drops is that?”

 Price: $39 US

Math is an aromatherapist's friend - and Hana will show you how you can befriend it, too!

In this guided workshop, we will explore the world of percentages, look at why you may want to switch to formulating in weight, and see how simple calculations can make your life easier as a formulator. The class is based on the most common questions from our students – and aims to give everybody the tools to tackle the challenges. 

No more confusion about how many drops to put in a product or how to recreate a formula you found online. This workshop will teach you how to be consistent and confident with your numbers. There will be regular check-ins throughout the lesson to make sure everything is clear. 

We will share good practice tips that come from the many decades of combined experience in the whole Tisserand Institute team. Are you ready to become a Math lover?
