Greetings all,
As part of my training for making perfume using naturals I am working through all my essential oils making notes on their characteristics and how they evolve on a smelling strip over a period of time - until they fade.
I have completed about 70 up till now.
This record is obviously subjective and I am keen to find out if there is a definitive directory, list or resource that has noted the evolution of essential oil scents on a smelling strip
Thanks and best wishes...
