Fragrance Notes

Science of Scents

We get into the technical details

What are top notes, heart notes and base notes? Fragrance notes explained

 

Much like musical notes make up a song and various shades of colours turn into a painting, fragrance notes are necessary to make a perfume. Overall, there are three note scales that when blended together create the perfume's fragrant accord. Each of these levels, however, has its own primary purpose.

 

The Top Notes

 

Also sometimes referred to as the opening notes or head notes, the top notes of a fragrance are generally the lightest of all the notes. They are recognised immediately upon application of the perfume. The top notes are also the first to fade given their light molecular structure, but this does not mean they aren't of utmost importance.

 

The top notes of a fragrance represent the first impression. How many times have you tested a fragrance only to be turned off right away? Why? Because the top notes didn't make a lasting impression on you. It is hugely important that the top notes not only succeed at luring you in, but also smoothly transition into the heart of the fragrance.

 

Common fragrance top notes include citrus (lemon, orange zest, bergamot), light fruits (grapefruit, berries) and herbs (clary sage, lavender).

 

The Middle Notes

 

The middle notes, or the heart notes, make an appearance once the top notes evaporate. The middle notes are considered the heart of the fragrance. They last longer than the top notes and have a strong influence on the base notes to come. A perfume's heart is generally pleasant and well-rounded. It is often a smooth combination of floral or fruity tones; sometimes infused with spices like cinnamon, nutmeg or cardamom.

 

Common fragrance middle notes include geranium, rose, lemongrass, ylang-ylang, lavender, coriander, nutmeg, neroli and jasmine.

 

The Base Notes

 

The base notes are the final fragrance notes that appear once the top notes are completely evaporated. The base notes mingle with the heart notes to create the full body of the fragrance, but are typically associated with the dry-down period. The job of the base notes is to provide the lasting impression. These often rich notes linger on the skin for hours after the top notes have dissipated.

 

Common fragrance base notes include cedarwood, sandalwood, vanilla, amber, patchouli, oakmoss and musk.

 

Without the combination of the three levels of notes, a fragrance just wouldn't be aromatically appealing. But together, they create beautiful scents.
