A Lexicon of Scent
What are notes, accords and undertones? What makes a perfume 'natural', and what exactly are chemicals? What's the difference between an essential oil and an absolute?
Find out using this glossary resource for perfumery terms. An alphabetised collection of the most essential words and phrases in the culture of perfumery.
Absolute: Highly concentrated perfume ingredient obtained by the alcohol extraction of the concrete. Absolutes usually come in the form of oil, much like essential oil, but are differentiated by the extraction method and odour intensity.
Accord: The basic character of a fragrance. Perfume accords are a balanced blend of three or four notes which create a completely new, unified odour impression.
Aldehyde: Aldehydes are an essential class of perfume ingredients that impart a vivid top note to the perfume. Aldehydes were first successfully incorporated into a perfume by Ernest Beaux in 1921 in Chanel No 5.
Amber: as a perfume group, amber is often synonymous with Oriental. However, amber also describes scents that are sweet, woody and earthy. Labdanum, vanilla and benzoin all have amber qualities. Amber as a note is almost always a blended scent rather than one particular ingredient.
Animalic: Characterized by bodily aromas or aromas most associated with traditional animal materials such as musk, civet and castoréum. These materials are now rarely used in commercial perfumes and have been replaced with musks obtained from plants and civet and castoréum smelling molecules obtained synthetically.
Aroma Molecules, Aroma Chemicals: Molecules obtained from natural products or made by synthetic organic chemistry that have an aroma. Most of the synthetic aroma chemicals are nature identical, i.e., identical to the same molecule obtained from a natural product. Aroma chemicals can be found in food, wine, spices, flowers, perfumes and essential oils. Many form biochemically (naturally) during the ripening of fruits. In wines, most form as by-products of fermentation.
Aromatherapy: The use of volatile plant oils, including essential oils, for psychological and physical well-being. The therapeutic use of pure essential oils and herbs in body massage, which is described by proponents as “healing, beautifying and soothing” the body and mind. The history of aromatherapy stretches as far back as 6,000 years ago in ancient Egypt. It wasn’t until the 1920’s, however, when the term was actually coined by a French chemist, R.M. Gattefosse.
Aromatic: Fragrance family or type denoting intense a spicey-grass scent embodied by a combination of citrus and woody herbs, particularly lavender.
Attar, Otto: From the ancient Persian word “to smell sweet.” Attar or Otto refers to essential oil obtained by distillation and, in particular, that of the Bulgarian rose, an extremely precious perfumery material.
Athonite Incense: Athonite Incense is a holy incensemade by hand by the monks of Mount Athos in an ancient tradition. The scents derive from the distillation the flowers, woods and resins of the flora of Mount Athos.
Ayurveda: A system of wellness with roots in India.
Balsamic: Sticky, resinous materials obtained from trees or shrubs which give a combined sweet-woody odour associated with well-seasoned, non-coniferous woods such as maple.Bandoline: Bandoline was a kind of hair fixer very popular in Western Europe during the 19th century. Contemporaneously, they were referred to as "fixatures" along with other products like wax pomatum. While wax was used very much as hair gel are used today - for example, to smooth down stray hairs - bandoline was used for the same purpose as hairspray used today: to fix a finished hairstyle in place.

Base Note, Fond: The base notes or “fond” (meaning “bottom” in French) are the underlying, most enduring tones. They are responsible for a fragrance’s lasting qualities.
Camphoraceous: a bracing, intensely green and pungent scent as found in eucalyptus, tea tree or bay leaf.
Chemical: Put simply, a chemical is a form of matter having constant composition and characteristic properties. Everything you can breathe, see, ingest or touch is made up of chemicals. Water is a chemical: Dihydrogen monoxide. The air we breathe is made of chemicals: Oxygen, Nitrogen, Hydrogen and many more. All matter, including us, is made of chemicals. An aroma chemical is simply a chemical that has an odour. There is no form of artistic expression more intimately connected with chemistry than perfumery.
Chypre: The French word for 'cypress' and often synonymous with the modern term Mossy-Wood. Chypre is a fragrance family or type describing a complex of moss mixed with woods, flowers or fruit odours.
Citrus, Hesperidic, Hespéride: Odours from citrus fruits such as orange, lemon, lime, mandarin and bergamot which give fresh, fruity top notes used especially in eau fraiche, classical and men’s colognes.
Civet: Also called Civet Musk, is obtained from the odorous sacs of the civets, animals in the family Viverride, related to the Mongoose. TPA does not use naturally derived civet because we love animals.
Cologne, Eau de Cologne: Contains the lowest concentration of 2-4% pure fragrance. It’s light, refreshing and can be applied often.
Concrete: Solid waxy substance obtained by the solvent extraction of plant material, e.g., flowers, bark, leaves, etc. The absolute is obtained by alcohol extraction of the concrete.
Coniferous: Odours reminiscent of cone-bearing trees and shrubs like pine.
Dry: A sensation produced by certain perfume ingredients which give a woody, masculine effect.
Dry Down: The final phase of a fragrance – the character which appears several hours after application. Perfumers evaluate the base notes and the tenacity of the fragrance during this stage.
Dry Wood: Part of the broader Wood Family, fragrances that are detectably drier through elements of cedarwood or burnt wood. Dried tobacco and leather are often characterised as dry wood.
Eau de Parfum: A perfume containing 8-20% pure fragrance mixed with alcohol or oil. The Parfum Apothecary perfumes are all eau de parfum to parfum grade at 20-25% concentration, meaning you can use less for the same impact, making each perfume last much longer.
Eau de Toilette: Contains 4-8% base. This form is light yet relatively lasting.Enfleurage: A perfume manufacturing technique that consisted of immersing raw materials in odorless fats that are solid at room temperature to capture the fragrant compounds exuded by plants. Petals are placed between layers of purified fat, which become saturated with flower oil, and alcohol is then used to obtain the absolute.
Essential Oil: The “essence” of plants obtained by distillation of the plant material or its concrete. Plant materials include flowers, grass, stems, seeds, leaves, roots, bark, fruits, tree moss and tree secretions.
Ethanol: Denatured ethyl alcohol is added to a fragrance compound to serve as the carrier. It modifies the fragrance intensity and makes application to the skin easier. The concentration of alcohol to perfume oils varies from perfumer to perfumer.

Fragrance Wardrobe: A collection of fragrances that a person owns to meet different moods, occasions, and even times of day.
Fruity: A fragrance family or type indicating scents of sweet, fresh or tart edible fruits, such as coconut, peach or pear. Citrus tends to not be included in this category as they have a classification all their own.

Macassar Oil: A compounded oil popularised by celebrated London barber, Alexander Rowland. In 1793, it became one of the first nationally advertised products, boasting extravagant claims of thickening and growth stimulation. It was an effective hair and beard styling agent, though, giving shine and lustre, and importantly adding scent. Read more about Macassar Oil as well as DIY formulas here.
Mossy Wood: Often referred to as Chypre fragrances, it is characterised by wet, grassy woody scents, like oakmoss.
Muguet: The French term for Lily of the Valley. One of three most used florals in perfumery.
Musk: Originally derived from the perineal glands of the Tibetan musk deer, the animal is now endangered and protected. Because we love animals, TPA only uses musk odours derived synthetically or from plants to achieve the same fragrant result. Musk adds a warming and sensual element to perfume.
Natural: in perfumery, refers to aroma chemicals that are produced by or using living organisms, such as plants or animals. Aroma molecules are produced naturally inside a living organism and then isolated as a distinct aromatic chemical. From a chemistry perspective, natural perfume ingredients are identical to lab-made aroma molecules. They have the same structure, behave the same way in and on the body and are identical in virtually every way. Perfumes labelled 'natural' perfumes commonly use essential oils, absolutes and concretes as opposed to fragrance oils.

They are often allowed to mature and dry in a controlled environment where the fragrances can amalgamate and become more coherent.
This is generally the main style of incense used in Levant cultures, where in Arabic it is known as bakhoor (بَخُورٌ), and in Eastern Orthodoxy as thimiama. Japan also has a tradition of kneaded incense called neriko or awaseko.

Perfumer: An expert or professional creating perfume compositions, sometimes referred to affectionately as a 'Nose' due to their fine sense of smell and skill in producing olfactory compositions.
Petrichor: the pleasant smell that accompanies the first rain after a long period of warm, dry weather.
