Confusing Terms from the World of Fragrances Explained

Perfume Glossary: 24 Key Fragrance Terms Explained Simply

If you’re just starting to explore the fascinating world of fragrances, don’t worry—it’s far less complicated than it seems at first glance. Perfumes are as exciting as they are complex, and once you know the key basics, you’ll find it much easier to navigate this olfactory world. So let’s dive right in with the fragrance terms everyone should know!

#1. Apocrine Glands (AP-o-kreen)

Apocrine sweat glands influence how a perfume interacts with your skin. If your favorite fragrance smells better on you than on your best friend, you can thank your apocrine glands.

#2. Fragrance Accords

A fragrance accord is the harmonious combination of two or more fragrance notes that together create a distinctive scent. You can think of fragrance accords like musical chords—only for the nose. They give a perfume its unmistakable character. A citrus-floral accord , for example, combines zesty citrus notes with floral nuances to create a balanced fragrance experience.

#3. Fragrances

Fragrance notes are the individual scent components that you can detect in a perfume. These include, for example, rose and lavender (as in Worthy) or leather and moss (as in PunkStar).

Fragrance notes are divided into three levels: Top notes, heart notes and base notes. The top notes are noticeable immediately after application. Next, the middle notes unfold, before the base notes finally linger as the long-lasting foundation of the fragrance.

Top Notes

Think of a perfume as a story. The top notes are the first lines. They’re the first impression your fragrance makes and, in a way, greet you with a friendly “Hello!” They usually consist of fresh citrus notes or light floral notes and create a memorable opening.

Heart Notes

The heart notes form the core of the fragrance composition. They emerge as soon as the top notes fade and linger significantly longer. This is where the true character of a perfume is revealed, through intense floral, spicy, or fruity nuances, for example.

Base notes

The grand finale. Base notes are the heaviest and, at the same time, the longest-lasting components of a fragrance. They mark the conclusion of the fragrance’s evolution and often consist of woody notes, musk, amber, or earthy accords, which lend the perfume depth and staying power.

This three-part structure forms the classic framework of a perfume. However, the number of individual fragrance notes in each layer can vary greatly. Some fragrances rely on just a few, clearly defined notes, while complex perfumes can consist of dozens of different ingredients. This creates a multi-layered and multifaceted fragrance profile that changes repeatedly throughout the day.

#4. Fragrance Concentration

In perfumery, the fragrance concentration refers to the proportion of fragrance oils or aromatic ingredients in a perfume. As a general rule, the higher the concentration, the more intense and long-lasting the scent. However, the fragrance notes used and their composition also play a decisive role in determining intensity and longevity.

EDT vs. EDP vs. EDC

Perfume (Extrait de Parfum), Eau de Parfum (EDP), Eau de Toilette (EDT) and Eau de Cologne (EDC) differ primarily in their concentration of fragrance oils. Parfum has the highest concentration, while Eau de Cologne has the lowest.

Perfume or Extrait de Parfum

Parfum, or Extrait de Parfum, has the highest concentration of fragrance oil and typically contains 20 to 30 percent—or even more—fragrance oil. This makes it particularly intense and ensures that it often lasts all day or even longer on the skin.

Eau de Parfum (EDP)

An eau de parfum typically contains between 15 and 20 percent fragrance oil. It is more intense than an eau de toilette and lasts about five to eight hours, depending on skin type and fragrance composition.

Eau de Toilette (EDT)

An eau de toilette typically contains between 5 and 15 percent fragrance oil. It has a lighter scent than an eau de parfum and usually lasts about three to four hours.

Eau de Cologne (EDC)

An eau de cologne has the lowest concentration of fragrance oils, usually between 2 and 4 percent. This gives it a particularly light and fresh scent, and it typically lasts only a few hours.

#5. Dry-down (Fragrance Development)

After a perfume is applied, it begins to unfold on the skin and gradually reveals its true character. This phase is known as “dry-down” . By this point, the volatile top notes have already faded, and the base notes, in particular, remain. You can compare the dry-down to the surprising twist at the end of a good story. Often, this phase is even more beautiful than the first impression.

That's why you should never judge a perfume based on just the first spray. Wait at least 30 minutes before deciding whether you really like a scent.

#6. Sillage

Sillage (pronounced: Sijasch) is a French term meaning roughly scent trail. It describes how strongly a perfume is perceived in the air and what scent trail it leaves behind as you move or leave a room. A strong sillage has a particularly pronounced presence and leaves a lasting impression, while a subtle sillage remains more intimate and understated.

#7. Fragrance Radiance

Radiance is a relatively new term in perfumery. It combines the concepts of projection and sillage and describes how elegantly and evenly a fragrance spreads throughout its surroundings. It is therefore less about how far a fragrance reaches and more about how harmoniously it fills the space.

#8. Projection

The projection describes how far a fragrance spreads from your skin while you’re wearing it. It answers the question of whether a perfume is perceived as being close to the body or is noticeable even from a greater distance.

#9. Fragrance Intensity

The Fragrance intensity describes how strong or distinct a perfume is perceived to be at a given moment. It is influenced by various factors, including the concentration of fragrance oils, the notes used, and the quality of the raw materials employed.

#10. Shelf Life

The Longevity describes how long a perfume remains detectable on the skin. Some scents last only a few hours, while others last all day or even longer. Which option you prefer is purely a matter of taste. Some people like scents that remain consistently present, while others particularly appreciate how a perfume evolves over the course of the day.

#11. Flavoring Chemicals

Fragrance chemicals, also known as synthetic fragrances or fragrance molecules, are compounds developed in the laboratory that replicate natural scents or enable entirely new olfactory experiences. They can reproduce the scents of flowers, fruits, woods, or spices, but also serve to make a fragrance composition more stable and long-lasting. Many modern perfumes combine natural raw materials with high-quality aromatic chemicals to create particularly well-balanced and long-lasting fragrances.

#12. Fragrance Family

A fragrance family is a classification system used to categorize perfumes based on their dominant scent characteristics. This makes it easier to compare scents and find suitable alternatives. Among the best-known fragrance families are:

  • Floral
  • Fresh
  • Woody
  • Oriental
  • Warm and Spicy
  • Citrusy
  • Gourmand
  • Aquatic

#13. Mouillettes (Mwee-Jett)

Mouillettes are the paper scent strips that perfumeries spray with perfume so you can test a fragrance without applying it directly to your skin. In German, they’re usually simply called scent strips or test strips .

Key Differences Between Fragrance Terms

Perfume vs. Extrait de Parfum

Both perfume and Extrait de Parfum are among the highest fragrance concentrations in perfumery. The term “Extrait de Parfum” is, however, usually used to refer to the particularly concentrated version. As a result, an Extrait often has a more intense scent, unfolds more slowly, and generally lasts longer on the skin than a classic perfume.

Sillage vs. Projection

Sillage describes the trail of scent that a perfume leaves behind as you move or leave a room.

Projection describes, on the other hand, how far the scent spreads from your skin while you're wearing it.

In short: Projection determines how far a fragrance travels, while sillage describes the impression it leaves behind after you've walked by.

Niche Fragrances vs. Designer Fragrances

Designer fragrances come from well-known fashion and luxury brands and are aimed at a broad audience. They are usually versatile, easy to wear, and developed for the commercial market.

Niche fragrances are created by specialized perfume houses that focus on extraordinary fragrance compositions, high-quality raw materials, and creative perfumery. Rather than trying to appeal to as many people as possible, they emphasize individuality and a distinctive character.

Niche Perfumes vs. Designer Perfumes: What's the Real Difference? 

Fragrance Intensity vs. Longevity

The Fragrance intensity describes how strong or noticeable a perfume is at a given moment.

The Longevity , on the other hand, indicates how many hours a fragrance remains detectable on the skin before it fades completely.

So a perfume can be very intense, but last only a few hours. Conversely, a fragrance can feel very close to the skin and still remain noticeable throughout the day.
