What is the typical duration of top notes in the body?

The typical duration of top notes in aromatherapy and perfumery is generally recognized to be relatively short, ranging from several minutes to an hour after application. Top notes are the initial scents perceived when a blend is first applied, and they often include lighter, more volatile essential oils such as citrus or herbal aromas.

The correct duration for top notes is often listed as lasting up to one hour, which is reflected in the available choices. This is because top notes quickly evaporate due to their lighter molecular structure, which causes them to dissipate faster than middle or base notes. This rapid evaporation contributes to the transient experience of top notes, leading to the brief enjoyment of their fragrance before the more stable middle notes take prominence.

The option indicating a duration of up to 24 hours, while describing a characteristic more applicable to base notes, misunderstands the volatility associated with top notes. Base notes, being heavier and slower to evaporate, extend the overall aroma experience significantly longer than the fleeting nature of top notes. Thus, recognizing that top notes serve primarily as an introduction to the overall fragrance blend is key to understanding their place in aromatherapy practice.
