What are perfume notes and how does the olfactory pyramid work

Like a symphony, each perfume is made up of an ensemble of essences that complement each other, creating a unique and memorable sensory experience. Since the creation of the first colognes in pharmacies in 1895, the art of combining essences has evolved, but the principle of olfactory harmony remains essential.

The structure of the olfactory pyramid

• Top notes: They form the first layer of the pyramid, being the most volatile and providing the first olfactory impression. They evaporate quickly, in about 15 minutes
  

• Middle notes: Also known as the "heart of the perfume", they define the central character of the composition and last for a few hours

• Base notes: They provide the foundation and longevity of the perfume, being able to be perceived for several hours or even a whole day

This pyramidal structure allows perfumers to create compositions that evolve over time, offering a dynamic and captivating olfactory experience. The harmony between these three levels is essential for the success of a perfume, each component contributing to the overall balance of the composition. Since the first formulas created in the laboratory, attention to detail and perfect balance have remained priorities. Understanding this pyramid is crucial to appreciate the complexity and art behind each perfume.

Perfume essences - top notes and the first contact with the scent

What are top notes?

Top notes represent the first contact with the olfactory universe of a perfume, being responsible for creating a memorable and attractive first impression. These volatile perfume essences are the ones that capture our attention in the first moments after application, often determining whether a perfume will attract us or not. Similar to carefully formulated pharmaceutical recipes, top notes are precisely dosed to provide a pleasant initial sensation.

Characterized by their light molecular structure, these perfume aromas evaporate quickly, lasting only for a short time - usually between 5 and 15 minutes. This rapid volatility allows them to create an immediate and intense impact, preparing the senses for the discovery of the deeper layers of the composition. This meticulous approach is reminiscent of the high standards in the pharmaceutical industry, where every detail counts.

The main categories of top notes

1. Citrus

• Characteristics: fresh, bright, energizing

• Common examples: lemon, bergamot, orange, mandarin, grapefruit, lime

• Associations: daytime perfumes, unisex perfumes, summer or sports perfumes

2. Aldehydic

• Characteristics: clean, sparkling, with a "fresh air" effect

• Examples: synthetic aldehydes (metallic, effervescent notes)

• Associations: classic, elegant, sophisticated perfumes

3. Aromatic / Green

• Characteristics: herbal, crisp, natural, often masculine

• Examples: mint, basil, rosemary, lavender, green leaves, green tea

• Associations: spring perfumes, fresh or fougère perfumes

4. Fruity

• Characteristics: sweet, juicy, sometimes tart

• Examples: green apple, peach, pineapple, red fruits, melon

• Associations: oriental, sensual, evening perfumes

The importance of their top notes in the perfume industry cannot be underestimated. They act as a "business card" for the perfume, being the first element that invites us to explore the complexity of the composition. Perfumers pay special attention to these components, knowing that they can determine the commercial success of a perfume through their ability to create a positive and memorable first impression. This attention to detail reflects the brand's heritage, founded on precision and quality. A successful first impression is essential, just as it is in pharmacy, where the first sensation counts enormously.

Middle notes - the heart of the perfume composition

What do middle notes represent?

After the top notes finish their ephemeral show, the olfactory stage is taken over by the middle notes, rightly considered the heart of any perfume composition. These components define the central character and personality of the perfume, representing its true essence and giving it a distinctive identity. Like a well-formulated medicine, middle notes are essential for the long-lasting effect of the perfume.

Middle notes manifest gradually, usually 15-30 minutes after application, when the volatility of their top notes begins to decrease. This transition is not abrupt, but is achieved through the harmonious layering of scents, creating a fluid and natural evolution. The persistence of these notes is considerably greater than that of the top notes, lasting between 2 and 4 hours, depending on the perfume's concentration and the ingredients used.

Main perfume ingredients for middle notes

1. Floral

• Characteristics: romantic, elegant, sensual, often dominant in feminine perfumes

• Common ingredients: rose, jasmine, tuberose, ylang-ylang, lavender, lilac, peony, violet

• Associations: sophisticated evening perfumes

The role of middle notes is crucial in establishing the olfactory family of the perfume - whether we are talking about a floral, oriental, woody, or fresh perfume. They create the bridge between the freshness of the top notes and the depth of the base notes, ensuring the overall coherence and balance of the perfume composition. This central position allows them to influence the overall perception of the perfume and remain in memory as its defining characteristic. This balanced approach reflects the brand's pharmaceutical expertise, where each ingredient has a specific role. Thus, middle notes are essential to create a memorable and harmonious olfactory experience.

Perfume base notes - the foundation of olfactory persistence

Characteristics of base notes

Perfume base notes constitute the solid foundation on which the entire olfactory architecture of a perfume is built, being responsible for the persistence and depth of the composition. These components are revealed gradually, only after the top notes and middle notes have made their presence felt, giving the perfume stability and remarkable longevity. Like the active ingredients in a medicine, base notes ensure the long-lasting effect of the perfume.

The manifestation of base notes usually begins 30-60 minutes after application and can last for several hours, sometimes even a whole day. This exceptional persistence is due to the more complex and heavier molecular structure of the ingredients used, which evaporate much more slowly than the volatile components of the other levels. This careful formulation is reminiscent of pharmaceutical precision, where stability is essential.

Types of base notes

1. Woody

• Characteristics: warm, dry, earthy, adding refinement and balance

• Common ingredients: sandalwood, cedar, vetiver, patchouli, guaiac wood

• Associations: masculine, elegant perfumes, winter perfumes

• Example: Terre d’Hermès – base with vetiver and cedar

2. Oriental / Balsamic

The main function of base notes is that of a natural fixative, helping to stabilize and prolong the duration of the other components of the perfume. They create a distinctive olfactory footprint that remains imprinted in memory and on clothes long after the perfume has been applied. This ability to leave a persistent trail makes base notes essential for creating a memorable and recognizable perfume, ultimately defining the long-term olfactory experience. This persistence reflects the brand's commitment to quality and durability, values cultivated since 1895. Thus, base notes are fundamental to a quality perfume, just as base ingredients are essential in a pharmaceutical formula.

Perfume ingredients and the main categories of olfactory notes

Types of perfume ingredients

The world of perfume ingredients is vast and diverse, encompassing an impressive range of natural and synthetic essences that combine to create complex olfactory compositions. These components are classified according to their origin, their aromatic characteristics, and the role they play in the perfume structure. Similar to the rigorous selection of pharmaceutical ingredients, choosing essences for perfumes is a complex process.

• Natural ingredients: Extracts from flowers, fruits, leaves, roots, wood, and resins, obtained through steam distillation, solvent extraction, or cold pressing

• Synthetic aromas: Molecules created artificially in laboratories that can faithfully reproduce natural aromas or create completely new notes

Natural ingredients include extracts from flowers, fruits, leaves, roots, wood, and resins, obtained through various extraction methods such as steam distillation, solvent extraction, or cold pressing. Bulgarian rose, Grasse jasmine, Indian sandalwood, or Madagascar vanilla are just a few examples of precious natural ingredients that give fragrances authenticity and refinement. These natural ingredients reflect the brand's tradition of using the finest resources.

Synthetic fragrances, developed in chemistry laboratories, have revolutionized the perfume industry by offering new creative possibilities and ensuring quality consistency. These artificially created molecules can faithfully reproduce natural aromas or create completely new notes that are impossible to obtain from natural sources. Aldehydes, synthetic musks, or amber molecules are examples of synthetic ingredients that have become indispensable in modern perfumery. Constant innovation, similar to pharmaceutical research, has enabled the creation of unique fragrances.

Main Fragrance Families

• Citrus: Bergamot, lemon, orange

• Floral: Rose, jasmine, lavender

• Fruity: Apple, peach, berries

• Green: Leaves, grass, mint

• Spicy: Cinnamon, pepper, cardamom

• Woody: Cedar, sandalwood, patchouli

• Oriental: Vanilla, amber, frankincense

• Marine: Aquatic notes, ozone

Each family contributes distinctive characteristics to the final personality of the fragrance, allowing perfumers to create compositions that meet diverse preferences and lifestyles. This rigorous classification reflects the brand's scientific approach, inherited from the pharmaceutical field. Thus, ingredients and classifications enable the creation of complex, personalized fragrances.

Searching for a Fragrance by Its Notes - How to Choose the Right Fragrance Composition

Choosing a fragrance based on its notes is a methodical, informed approach that helps identify the ideal fragrance composition according to personal preferences. This selection strategy goes beyond initial attraction and focuses on understanding the olfactory structure and how it will evolve on the skin.

Just as a doctor looks for symptoms to prescribe the correct treatment, identifying preferred notes is essential when choosing the right fragrance.

How to Identify the Right Fragrance

1. Identify preferred fragrance families based on an attraction to citrus freshness, floral elegance, or oriental warmth

2. Analyze the fragrance composition at all three levels of the olfactory pyramid

3. Carefully examine the middle notes and base notes, which define the long-lasting character

4. Test the fragrance on the wrist and observe how it evolves over a few hours

5. Note how the aromas change and which ones you like best

The first step in finding the right fragrance is identifying preferred fragrance families. If you are drawn to citrus freshness, look for fragrances with top notes rich in bergamot, lemon, or grapefruit. For flower lovers, compositions with rose, jasmine, or peony in the middle notes will be ideal. Those who prefer warmth and sensuality will opt for fragrances with oriental or woody base notes.

Testing on the skin is essential, as individual chemistry can significantly influence how fragrance notes manifest. This meticulous approach reflects the attention to detail cultivated by the brand throughout its history. Similar to testing a medication, testing a fragrance on the skin ensures compatibility and satisfaction. Choosing the right fragrance is a personal process, but with a methodical approach, you will find the perfect fragrance composition.

The Evolution of Fragrance Notes on the Skin and Influencing Factors

How Does a Fragrance Evolve on the Skin?

The evolution of a fragrance on the skin is a fascinating and complex process, influenced by multiple factors that can significantly alter olfactory perception. This dynamic transformation makes every experience with a fragrance unique and personalized, reflecting the interaction between the fragrance composition and the wearer's individual characteristics. Like the reaction of a medication in the body, the evolution of a fragrance is an individual process.

Main Influencing Factors

• Skin chemistry: pH level, skin type, and the natural composition of sebum can accelerate or slow the evaporation of certain components

• Body temperature: Higher temperatures accelerate evaporation, causing the fragrance to manifest more intensely initially

• Environmental factors: Humidity and ambient temperature affect the evolution of the fragrance

Skin chemistry plays a fundamental role in how fragrance notes manifest. pH level, skin type (dry, oily, or combination), and the natural composition of sebum can accelerate or slow the evaporation of certain components. Skin with a more acidic pH tends to intensify citrus and floral notes, while skin with a more alkaline pH may accentuate woody and oriental notes.

Body temperature directly influences the volatility of fragrance ingredients. Higher temperatures accelerate evaporation, causing the fragrance to manifest more intensely initially, but fade more quickly. Warmer areas of the body, such as the neck, wrists, or behind the ears, are ideal places to apply fragrance, as natural warmth helps diffuse the aromas.

Environmental factors, such as humidity and ambient temperature, also affect the evolution of the fragrance. Damp weather tends to intensify and prolong the persistence of aromas, while dry air can accelerate evaporation. These factors explain why the same fragrance may be perceived differently depending on the season or climatic conditions. This complexity underscores the expertise required to create a quality fragrance, a legacy of the brand dating back to 1895. Understanding these factors helps you fully appreciate the art of perfumery.
