Aroma Notes - Working with Top Note Essential Oils
Top Note Essential oils typically evaporate faster than middle and base notes. For this reason, it is necessary to have more top note oils in a blend than middle and base notes, whose notes will carry farther and last longer - that is, if you wish to have a balanced blend that does not change dramatically over a short period of time.
Top Note Essential oils are usually very light, fresh and uplifting scents. It is usually the top note that you will smell first.
