Testing: a Necessary Part of Formulating



One of the things I enjoy doing (to the surprise of many) is ‘testing stuff’.

Sometimes, I’m examining a theory that may or may not be correct - or a theory will have nuances that might not have been considered. Sometimes my own idea about an ingredient or work process will call for initial tests before proceeding to create a formula.

All in all, it adds up to cupboards and shelves filled with ‘experiments underway’ that need monitoring.

And before you start thinking I am constantly running around in a lab car with my notebook in hand, allow me to reveal that

  1. I don’t own a proper lab coat

  2. but I do have notebook in hand

  3. Since the time I discovered an herbal vinegar infusion that had been forgotten in the back of a cupboard for over a year, I have learned to downsize some of the test vials I use. (To my amazement, the infusion was still good, which of course brought on a slew of new questions and further tests)

Above: some testing I did earlier this year in connection with the course at Tisserand Institute I am teaching this summer. Essential Formulation, oils based products and aqueous sprays.

Please visit this page to learn more about the course and to sign up, but don’t wait too long. Enrollment is only open until June 30th. I hope you’ll be joining us!
