Perfume Notes: How to Read the Pyramid

A note is a verbal description of a scent impression. IFRA, the International Fragrance Association, explains a composition in terms of opening, middle and base roles. Top notes introduce the fragrance, middle notes shape its main character, and base notes provide depth. This helps you read the description but does not reveal the laboratory formula.

For example, when you read the word “rose,” first think of the impression being described. Do not use that word alone to decide which raw material was used. IFRA describes both natural and synthetic fragrance materials. A synthetic material is a substance produced through chemical processes; its name and the note presented to the consumer are different things.

Editorial suggestion: next to the list of notes, write down what you want to check. Instead of deciding in advance, “rose will not suit me,” write the question, “do I smell delicate petals here, or a richer floral impression?” This makes the description a starting point for testing. What you write down does not confirm the manufacturer’s formula.

Top notes describe the initial impression of a fragrance. Evaporation, the diffusion of substances through the air and their perception through the sense of smell are important to fragrance development. These processes are considered together in a peer-reviewed engineering review; note names alone are not enough to calculate how a fragrance will behave.

Volatility means a substance’s tendency to enter the vapour phase. Perfume, however, is a mixture. The review discusses both the effect of the mixture’s base on evaporation and the contributions of different substances to the perceived scent. Top notes are therefore not a separate liquid sitting above the other layers.

Record the opening impression separately from your final choice. You might note “fresh,” “slightly sweet” or “sharp” without guessing which molecule causes it. Return to the same test later. There is no need to specify a minute at which the opening must end.

Heart notes describe the central character of a composition. IFRA presents them as the part that supports the fragrance’s structure. In this model, the terms “heart” and “middle” refer to the same group of notes.

Read this part together with the opening and base. If the description names spices alongside flowers, check their balance when you test the fragrance. Are the flowers more noticeable to you? Is the spicy impression acceptable? Describe what you smell, even if your words differ from those chosen by the manufacturer.

For this article, MARABIKA did not measure note longevity: not measured. We therefore do not give a universal start or end point for heart notes. When testing the fragrance, write down what you actually perceive rather than trying to fit the impression to an assumed timeline.

In the model, base notes are associated with a background that lasts longer and with the composition’s depth. IFRA describes this role qualitatively. This explanation is not a promise that every fragrance with a wood or musk note will last for a set number of hours.

Treat the base as a question to explore in your own test. For example, is the fragrance’s later impression still pleasant? Would you like to wear this fragrance again? Would your choice be the same if you could not see the list of notes? This helps you return to the experience rather than tally promises.

Do not infer the longevity of the entire composition from a single word in its base. The engineering review indicates that studying fragrance behaviour requires information about the materials, the mixture and the test conditions. A list of notes does not provide such data.

No. Notes explain a fragrance’s character, while the ingredient list on the label serves a different purpose. Article 19 of Regulation (EC) No 1223/2009 of 30 November 2009 provides for the terms “parfum” or “aroma” for perfume and aromatic compositions. It also provides for the separate indication of relevant substances in Annex III.

It would therefore be incorrect to say that the fragrance component is always indicated by only one word, or that the name of a botanical raw material cannot appear on the label. A list of notes does not replace mandatory information. Check the packaging of the selected product, not the label of another fragrance from the same brand.

Regulation (EU) 2023/1545 of 26 July 2023 amended the labelling requirements for fragrance allergens. In the transitional cases described in its Annex, products that do not comply with the new restrictions must comply with the restrictions applicable on 15 August 2023. Such products could be placed on the EU market until 31 July 2026; that deadline has now passed. They may be made available on the EU market until 31 July 2028. These are different stages.

This is a general explanation of labelling. This text is not legal or medical advice. If you have questions about an allergy or skin reaction, consult a doctor. Do not use the fragrance pyramid for self-diagnosis.

Read all groups of notes, choose one impression you want and one thing you want to avoid. Then test the fragrance in practice. For example, instead of asking “is there vanilla?”, ask yourself “is the sweetness I perceive acceptable to me?”

A paper blotter strip can help with initial screening. The Perfume Society recommends also getting to know the fragrance on skin before deciding, if the product is intended for that use and using it that way is suitable for you. This is practical advice, not a laboratory test or medical confirmation.

Write down the name, the testing location, and your impression at the beginning and later. If you do not perceive a difference, do not invent one. Do not feel that you must identify every note. The fragrance as a whole matters to your choice, and the note-taking sequence proposed in this article helps you compare tests consistently.
