Perfume is a mixture of fragrant essential oils or aroma compounds, fixatives, and solvents, typically in liquid form, used to give the human body, animals, food, objects, and living spaces a pleasant scent. While modern perfumes often contain synthetic odorants, plants are the largest source of fragrant compounds used in perfumery. These fragrant compounds are derived from various parts of a plant, including flowers, seeds, bark, roots, and blossoms. To extract the fragrant compounds, perfumers use methods such as steam distillation, solvent extraction, enfleurage, and maceration. The extracted compounds are then blended with alcohol and sometimes water to create the final perfume product.

Maceration/solvent extraction
The maceration/solvent extraction process involves submerging raw materials in a solvent that can dissolve the desired aromatic compounds. Common solvents used for this process include hexane, dimethyl ether, benzene, and petroleum ether. The plant parts eventually dissolve in the solvent, leaving a waxy substance that contains the oils. This process can take anywhere from hours to months, depending on the raw materials used and the desired level of fragrance concentration.
During maceration, the flowers are left to soak in a carrier oil, such as coconut oil, to absorb the fragrance. This process can take several weeks or even months for the oil to become saturated with the aroma compounds. As the oil becomes saturated, the flowers are replaced with fresh ones, and this process is repeated multiple times to enhance the fragrance concentration.
Once the desired aroma intensity is achieved, the macerated mixture is carefully filtered to remove any residual flower material. The resulting aromatic oil can then be used as a fragrance or incorporated into various cosmetic products, perfumes, and skincare items.
While maceration/solvent extraction is a widely used technique, it is important to note that it may not produce as intense of a fragrance as other methods. Additionally, the use of heat, chemical solvents, or exposure to oxygen during the extraction process can denature some aromatic compounds, altering their odour or rendering them odourless.

Steam distillation
The process of steam distillation has been used since ancient times, with evidence of its use in the 2nd millennium BC. It is a widely used technique today, producing essential oils that are then used in perfume-making. The perfume distillation process involves placing plants in large steel tanks, known as stills, topped with serpentine pipes. Then, between five and ten times the volume of water is added, and everything is heated. The steam traps the fragrance of the plants as it rises in the serpentine pipe.
The liquid that is separated from the essential oil during steam distillation is called floral water, hydrolats, or hydrosols. It is used for cosmetics and other products. The amount of aromatic components contained in plants is limited, so attention must be paid to the speed and duration of the steam flow. This is because too much steam can cause changes in the aromatic components or dilute the concentration of flower water. Steam distillation is used for the extraction of many plants because it is relatively inexpensive and can be used in large quantities.
However, it is not suitable for all plants. Steam distillation is not appropriate for citrus plants such as lemons and bergamot, as the heat-sensitive main aroma components will change and decompose when exposed to heat for long periods. It is also not suitable for extracting water-soluble fragrance components, as they will dissolve into the water during the distillation process.

Boiling
During the boiling process, the plant material is submerged in water and heated. This causes the plant's cells to rupture, releasing the aromatic compounds and essential oils. The steam produced carries these fragrant molecules, which are then condensed back into water through a cooling process. This allows for the easy separation of the fragrant oils from the water. The water collected from the distillation process, known as hydrosol, retains some of the fragrant compounds and is sometimes sold.
The boiling method is particularly suitable for fresh plant materials such as flowers, leaves, and stems. It is an effective way to extract aromatic oils from plants and has been used for thousands of years. Ancient civilizations, such as the Egyptians, used this technique to create perfumes and incense. They would boil plants like frankincense, myrrh, and jasmine to extract their fragrant oils.
Today, the boiling method is still used in perfumery, especially for creating perfumes with a strong, concentrated scent. The extracted oils are then blended with other ingredients, such as alcohol, to create the final perfume product. This process of mixing and ageing the fragrance is an important step in creating a unique and appealing perfume.
While the boiling method is ancient, modern distillation techniques have improved the process. For example, the use of a Florentine flask during distillation allows for better separation of oils and water. Additionally, advancements in extraction methods have led to the development of other techniques, such as solvent extraction and enfleurage, which are more suitable for certain types of plant materials.

Enfleurage
Cold enfleurage involves smearing a layer of animal fat (usually lard or tallow) onto a large framed glass plate called a "chassis". The fat is then allowed to set, and botanical matter (usually petals or whole flowers) is placed on top. Over the course of 1-3 days, the scent of the flowers diffuses into the fat. This process is repeated with fresh flowers until the fat reaches the desired level of fragrance saturation. It typically takes up to 60 days and at least 30 charges to render a highly fragrant fat, which is then called a "pomade".
Hot enfleurage involves heating the solid fats and stirring the botanical matter into it.
Once the fat is saturated with fragrance, it is called the "enfleurage pomade". The pomade can be sold as-is, or washed or soaked in ethyl alcohol to draw out the fragrant molecules. The alcohol is then separated from the fat and allowed to evaporate, leaving behind the absolute of the botanical matter. The spent fat is usually used to make soaps.

Expression
The expression method was commonly used by ancient civilisations in Egypt, Persia, Rome, and China. These civilisations also used other methods such as distillation, which was invented by the Persian chemist Avicenna in the 10th century, and enfleurage, which involved placing flowers or organic material in a fat or oil base to extract the fragrance.
Today, there are six main methods of extracting oils from plants: steam distillation, boiling, solvent extraction, enfleurage, maceration, and expression. Maceration and solvent extraction are the most commonly used techniques in the modern perfume industry, as they are economically important and can be used to extract a wide range of aromatics.
However, expression is still a valuable technique, especially for citrus oils, and it is one of the simplest and oldest methods of extracting plant oils.

Frequently asked questions
The sources of fragrant compounds in plants can vary depending on the plant. For example, orange leaves, blossoms, and fruit zest are the respective sources of petitgrain, neroli, and orange oils. Flowers and blossoms are the most common source of perfume aromatics, including rose, jasmine, osmanthus, and ylang-ylang.
Common methods of extracting fragrant compounds from plants include steam distillation, boiling, solvent extraction, enfleurage, maceration, and expression. Steam distillation involves passing steam through plant material to turn the essential oil into gas, which is then cooled and liquefied. In solvent extraction, flowers are placed in rotating tanks with benzene or petroleum ether to extract the essential oils.
Synthetic chemicals are used to emulate scents that do not occur in nature or are hard to extract from natural sources. Synthetic aromatics can also create original scents not found in nature, such as Calone, which imparts a fresh ozonous metallic marine scent. Synthetic perfumes offer more freedom and stability to perfumers and are more cost-effective.
Alcohol is used to dilute ingredients in perfumes and plays a crucial role in determining the final product. The ratio of alcohol to scent differentiates a perfume, eau de toilette, and cologne. Perfumes typically contain about 10-20% perfume oils dissolved in alcohol, while colognes contain approximately 3-5% oil diluted in 80-90% alcohol.
