Fragrance 101Fragrance notes, A to Z

Fragrance notes, A to Z

A comprehensive reference of individual fragrance notes, the actual chemical compounds most commonly responsible for each one, and what to realistically expect in terms of longevity and sillage. This isn't an exhaustive list of every aroma chemical in existence, it's the notes you'll actually see on fragrance pages across this site.

How to read “longevity” and “sillage” here

Longevity and sillage in this table describe the note in isolation, based on the volatility of its dominant chemical compounds, not how it behaves once blended into a finished fragrance. A heavy base note can still fade fast if it’s used at a low concentration, and a light top note can be boosted with fixatives to last longer. Treat this as a baseline, not a guarantee.

Top notes

The first 5 to 15 minutes. Small, light molecules that evaporate fast and create the opening impression.

NoteCommon chemicalsExpectCharacter

Bright, slightly bitter citrus. Gone within 20 minutes unless fixed.

AldehydesC-10, C-11, C-12 aldehydes
Longevity
Sillage
Waxy, soapy, "sparkling" effect popularized by Chanel No. 5.

Heart notes

Roughly 30 minutes to 3 hours in. Medium-volatility molecules that form the main character of the fragrance.

Sillage
Powdery, cool, faintly carrot-like. One of the most expensive natural materials.

Cool, eucalyptus-tinged spice. Often bridges citrus into a spicier heart.

Base notes

Three or more hours in, often through the rest of the day. Heavy, low-volatility molecules that anchor the fragrance and show up most in the dry-down.
