The use of fragrances dates back thousands of years, with the ancient Egyptians using scented oils for cleaning, skincare, and to mask body odour. The art of perfumery has evolved from basic distillations of plants and essential oils to a multi-billion dollar industry. Today, fragrances are used in various sectors, including cosmetics, food, and personal care products. The language of perfumery is complex, with fragrances designated according to their concentration level, scent family, and notes. The sense of smell is heavily linked to memory and can have a strong psychological impact on individuals, influencing their moods, alertness, and learning abilities. The study of fragrances involves understanding the science behind scent creation, the impact of fragrances on human behaviour, and the role of perfumers and perfume chemists in developing new fragrances.

What You'll Learn
Fragrance in history
Fragrance has been a part of human history for over 4,000 years, with the first known evidence of perfume-making dating back to the Bronze Age. The ancient Egyptians distilled botanical fragrances like attar and lily, not only to smell pleasant but also as a sign of social status. Egyptian mythology even recognised Nefertem, the lord of perfume, who was often depicted carrying water lilies. The ancient Persians also played a significant role in the history of perfumery, ruling the perfume trade for hundreds of years and inventing non-oil-based perfumes.
The art of perfumery in Western Europe was reinvigorated after the Islamic invasion of Spain and Southern Italy in the 8th and 9th centuries. The Islamic-controlled cities of Spain, known as Al-Andalus, became major producers of perfumes that were traded throughout the Old World. The Andalusians used fragrances in devotion to God, and also for courtship, as women enjoyed greater freedoms compared to those in other Muslim-controlled regions.
During the Middle Ages, distillation techniques improved, and trade routes broadened, leading to an increase in the variety of available scents. Florence, Italy, became the epicentre of perfumery during the Renaissance, with recipes recorded by monks of Santa Maria Delle Vigne or Santa Maria Novella of Florence from 1221. The beginning of modern-day perfumery is also attributed to this period, championed by the influential Medici family.
By the 19th century, synthetic fragrances were introduced, including aldehydic compounds, and some of the world's most iconic scents were created. The creation of synthetic aroma compounds such as vanillin and coumarin in the late 19th century marked the beginning of modern perfumery. This commercialisation allowed for the composition of perfumes with diverse smells, making them more accessible to the masses.
In the 20th century, fragrance became widely popular as a gift and token of affection. Today, fragrances are marketed to enhance attractiveness to the opposite sex or to express personal tastes and style. The sense of smell is heavily linked to memory, and the perfume industry, worth billions of dollars annually, caters to our desire to evoke certain memories and emotions through scent.

Fragrance concentration classifications
The fragrance concentration of a perfume refers to the strength of the fragrance. The higher the concentration, the more pure the fragrance, as it contains a greater amount of perfume oils and less alcohol. The higher concentration of perfume oils also means that the scent will last longer on the wearer's skin. The higher concentration of oils also generally means a higher price.
There are four major perfume concentration classifications:
- Parfum: This has the highest concentration of perfume oils, typically between 15 and 30% but can go up to 40% or even 45%. Parfum fragrances are long-lasting and expensive.
- Eau de Parfum (EdP): Eau de Parfum has a lower concentration of perfume oils, typically between 10 and 20%, but some sources put the range at 15 to 25%. It is one of the most popular fragrance concentrations and is usually stronger in scent and performance than Eau de Toilette.
- Eau de Toilette (EdT): This has a lower concentration of perfume oils, typically between 4 and 15%. It is also a very popular type of fragrance and is known for its versatility and affordability.
- Eau de Cologne (EdC): This has a low concentration of perfume oils, typically between 2 and 5%. It is one of the lightest fragrance concentrations and is usually the cheapest.
There are also a few other, less common, fragrance concentration classifications:
- Esprit de Parfum: With 15–30% aromatic compounds, this is a seldom-used strength concentration between EdP and Parfum.
- Eau Fraiche: This has a perfume oil level of around 1–3% and is even lighter than Eau de Cologne.
- Extrait de Parfum: With 35–45% essential oil concentration, this is the most concentrated form of fragrance available on the market. It is also the most expensive, longest-lasting, and best-performing.

Fragrance and gender
Fragrance has been used as a form of personal expression and to enhance one's attractiveness to the opposite sex. The fragrance industry has traditionally marketed certain scents as being inherently masculine or feminine, with fruity, floral, and sweet scents targeted towards women, and musky, spicy scents towards men. This gendering of fragrances is a relatively modern concept, arising from the late 19th century as a marketing technique to cater to the growing middle and lower classes during a time of rapid economic growth and shifting gender roles.
The idea of gender-specific fragrances is deeply rooted in our upbringings and memories. We tend to associate certain fragrances with masculinity or femininity based on what our parents or caregivers wore and our cultural context. For example, a woman might consider a man wearing cologne with musk as attractive because musk is associated with virility. Similarly, vanilla-scented perfume on a man may conjure memories of baked goods and make him seem more approachable. However, the same scent on another person could be off-putting due to the unique associations and memories of the individual.
The fragrance compounds in a perfume or cologne also react differently with each person's skin chemistry, which is unique to each individual. Women, for instance, tend to have more acidic skin than men, which can cause a fragrance to smell differently on them compared to a man wearing the same scent. This adds another layer of complexity to the perception of fragrances and their association with gender.
In recent times, there has been a shift towards more gender-neutral fragrances, with companies like Olfactory NYC and indie brands like Sigil creating fragrances that are marketed as unisex. This movement is being driven by younger fragrance enthusiasts who are challenging traditional marketing conventions and embracing fragrance as a form of self-expression rather than a tool of seduction.
Additionally, some celebrities and fashion designers are also embracing the idea of gender-fluid fragrances. For instance, pop star Billie Eilish launched an ungendered fragrance called "Eilish", and fashion designer Tom Ford's first fragrance, "Black Orchid", was intended to smell like "a man's crotch". These examples further challenge the traditional gender associations with fragrances and offer a more inclusive and diverse range of scent options for consumers.

Fragrance and psychology
The use of fragrance is almost as old as civilisation itself, with the oldest evidence of perfume-making dating back to the Bronze Age, nearly 4,000 years ago. The first chemists were perfumers who worked in Mesopotamia, and the art of perfumery was reinvigorated in Western Europe after the Islamic invasion of Spain and Southern Italy in the 8th and 9th centuries.
Today, the fragrance industry makes billions of dollars in profit each year, catering to our sense of smell. While the sense of smell is often underrated, it is one of the most powerful human senses. Scents have the power to evoke memory and emotion, and can create an ambiance that affects both mood and behaviour.
The brain processes and identifies smells using a complex network of olfactory receptors, integrating it with information received through the other senses. The olfactory system is unique in that it bypasses the brain's thalamus and directly connects to the limbic system, the brain's emotional centre. This means that scents have a direct and powerful impact on our emotional processing and memory formation.
In terms of fragrance choice, socio-cultural factors have been found to play a role, with young women, for example, found to be the most conformist in their perfume preferences, choosing fragrances that are popular among their peers. Fragrances are also used to modulate body odour, with cultural standards around the use of fragrances varying between different countries.
In addition, fragrances are often marketed as a way to make the wearer more attractive to the opposite sex. For example, a woman may consider a man who wears cologne containing musk to be attractive because of the association of musk with virility. However, because the sense of smell is heavily linked with memory, an odour that is considered attractive by one person may be off-putting to another.

Fragrance and health
Fragrances are almost as old as civilisation itself, with the oldest evidence of perfume-making dating back to the Bronze Age, nearly 4,000 years ago. Ancient Egyptians distilled botanical fragrances like attar and lily, not only to smell pleasant but also as a symbol of social status. The use of fragrances has evolved over the centuries, with perfumers creating scents that cater to various preferences and purposes.
Today, the fragrance industry is a booming business, with companies investing billions of dollars annually to appeal to our sense of smell. Fragrances are designed to make the wearer more attractive to others, with certain scents like musk and vanilla-based perfumes perceived as more approachable and open. The sense of smell is closely linked to memory, and a pleasant fragrance can enhance one's mood, confidence, and overall wellbeing.
However, fragrances can also pose potential health risks. For example, balsam of Peru, commonly used in perfumes, is one of the top five allergens, causing patch test reactions in people with dermatological issues. Additionally, some studies have indicated that certain chemicals used in fragrances, such as nitro-musks, may have carcinogenic properties in specific animal tests.
To address these concerns, companies like Givaudan have established research centres, such as the Health and Wellbeing Centre of Excellence in Ashford, UK, to gain insights into how fragrances impact our thoughts, emotions, and behaviours. They have also developed innovative technologies like the Z‑biome™ platform, which offers microbiome-friendly fragrances that respect the skin's delicate microbiome. These advancements demonstrate a growing awareness of the connection between wellbeing and skin health in the fragrance industry.
Furthermore, oral care is another area where fragrances play a role in emotional wellbeing. Companies develop products like toothpaste and mouthwash that not only smell and taste great but also provide a sense of freshness and boost confidence throughout the day. This integration of fragrances into oral care routines reflects a holistic approach to enhancing emotional wellbeing.
