Top Notes
Also known as: Head Notes, Opening Notes
The scent impressions that define a fragrance’s opening, also called head notes. They shape the first impression and can overlap with the heart and base.
Top notes describe what stands out early after a fragrance is applied. Citrus and green or herbal impressions are common examples, but the exact opening depends on the composition.
The whole fragrance is applied together. Calling something a top note does not mean it is a separate layer sprayed on before the rest, or that every other note is initially absent. IFF’s Iso E Super entry, for example, lists impact in the top, heart and base for the same woody material.
Top notes are usually the smallest, most volatile molecules, such as limonene and citral in citrus oils, which is why the opening fades first.
