What is a key characteristic of top note oils?

Top note oils are characterized primarily by their quick evaporation. These oils are typically the first scents that are perceived when a blend is applied, and they are often described as having a light, refreshing quality. Due to their volatilities, top note oils diffuse rapidly, which is why they are noticed first but do not last as long as middle or base notes.

In aromatherapy, common examples of top note oils include citrus oils like lemon and orange, as well as lighter floral scents. Their fleeting nature is essential in the balance of an essential oil blend, providing an initial burst of fragrance that attracts attention but quickly gives way to the more sustained middle and base notes. This characteristic significantly influences how an aromatherapy formulation is experienced over time.
