Top Notes
What they are: Top notes are the first impression of a fragrance. These are the lightest and most volatile molecules, evaporating quickly after you apply the scent. They provide the initial burst that draws you in but typically last only 15 to 30 minutes.
Chemistry: Top notes are made up of smaller, more volatile molecules that evaporate quickly because of their low molecular weight. The lightness of these molecules is what allows them to be detected first.
Best examples:
Citrus: Bergamot, lemon, orange
Herbs: Basil, mint, rosemary
Fresh and Fruity: Apple, peach, pineapple
