What is a typical characteristic of base notes in essential oils?

Base notes in essential oils are known for their slow evaporation rates and their ability to linger on the skin and in the air for extended periods, often lasting for several days. This lasting quality is due to their larger and heavier aromatic molecules, which take longer to evaporate compared to top and middle notes. Base notes provide depth to a blend and often serve as a foundation for the overall aroma, enhancing the longevity of the scent.

This characteristic makes them particularly valuable in perfumery and aromatherapy, as they contribute to the overall complexity and lasting impression of the fragrance. The other characteristics, such as quick evaporation or light citrus aromas, align more closely with top notes, which are typically more volatile and fleeting in nature. The inclusion of base notes is also crucial for grounding a blend, as they stabilize the more transient elements of a fragrance.
