Description of Perfume
The exact formulas of perfumes sold around the world are kept top secret by perfume houses, even so there are many perfume connoisseurs that overtime have become skilled in the art of identifying what makes up a perfume and the origin of the fragrance. The most sensible way to commence describing a perfume is its concentration level, the family it belongs to and the notes of scent, which will all affect the overall sense of a perfume.
Perfume oil is diluted with solvents such as ethanol, neutral smelling lipids like johoba, coconut oil or wax. Dilution of perfume oil is a must, because undiluted oils contain high levels of volatile components; that are likely to cause allergic reactions and even injury if applied directly to skin or clothing. Perfume extract is made up of 20-40% of aromatic compounds, eau de parfum 10-30%, eau de toilette 5-20% and eau de cologne 2-5%. As the percentage of the aromatic compound is lowered, so is the intensity and permanence of the created scent.
Grouping perfumes is like any form of classifying, it can never be completely an objective or final process. Many fragrances contain aspects of different families, unitary scents can hardly ever be found in perfumes, as it requires the perfume to exist only as a singular aromatic material. The classification of perfumes needs to commence with an understanding of what is used to create the fragrance. The traditional classifications which began to spring up around the 1900's are:
- Single floral:
- Fragrance dominated by a scent from one particular flower.
- Floral Bouquet:
- Containing the blend of several flowers in a scent.
- Ambery:
- A large fragrance class featuring the scents of woods, flowers, animal scents and vanilla. These can be enhanced by camphorous oils and incense resins, which date back to the times of the Victorian era, the Ancient Far East and Middle East.
- Woody:
- Fragrances that are dominated by woody scents, typically of sandalwood and cedar.
- Leather:
- A family of fragrances which features the scents of honey, tobacco wood and wood tars in its middle or base notes and a scent that alludes to leather.
- Chypre:
- Fragrances built on a similar accord consisting of bergamot, oakmoss, patchouli and labdanum.Fougere: Built on a base of lavender, coumarin and oakmoss, many men's fragrances belong to this family; characterized by its sharp herbaceous and woody scent.
- Since 1945, due to technological advances in compound design and synthesis along with the natural development of styles and tastes; new categories have emerged to describe modern scents:
- Bright Floral:
- Combining the traditional Single Floral & Floral Bouquet categories.
- Green:
- A lighter and more modern version of the Chypre type.
- Oceanic/Ozone:
- The newest category in perfume history, a very clean, modern smell leading to many of the modern androgynous perfumes.
- Citrus or Fruity:
- An old fragrance family that until recently consisted mainly of "freshening" eau de colognes due to the low tenacity of citrus scents. Development of newer fragrance compounds has allowed for the creation of primarily citrus fragrances.
- Gourmand: Scents with "edible" or "dessert" like traits. These often contain notes like vanilla and tonka bean, as well as synthetic components designed to resemble food flavors.
- In 1983 a perfume consultant Michael Edwards developed a new classification method, called the fragrance wheel; he created this scheme to simplify the classification and naming system, Edwards also wanted to show the relationships between individual classes. The five standard families consist of Floral, Oriental, Woody, Fougere, and Fresh, with the previous four families being more "classic" while the latter consisting of newer bright and clean smelling citrus and oceanic fragrances that have evolved due to developments in fragrance technology. With the exclusion of the Fougere family, each the families are in turn seoarated into three sub-groups and set around a wheel:
- Floral:
- Floral, Soft Floral, Floral Oriental
- Oriental:
- Soft Oriental, Oriental, Woody Oriental
- Woody:
- Wood, Mossy Woods, Dry Woods
- Fresh:
- Citrus, Green, Water
- Fougere:
- The Fougere family is located at the center of this wheel, due to the fact they are a large family of scents that usually contain fragrance elements from each of the other four families.
Perfume is often described metaphorically as having three musical "notes", which make up the melodious chord of the fragrance. Over time the notes unfurl with the instant impression of the top note leading to the deeper middle notes, and the base notes gradually coming out at the final stage. These notes are carefully shaped with knowledge of the evaporation process of the perfume.
The top note scents are immediately apparent upon application of a perfume. Top notes consist of tiny, light molecules that evaporate quickly; they form a person's initial impression of a perfume and thus are extremely important in the selling of a perfume.
The middle note is the scent of a perfume that appears after the top note dissipates; the middle note compounds the main body of a perfume. The middle note also acts to mask the often unpleasant initial impression of the base notes, which become more pleasant with time. Not surprisingly, the scent of middle note compounds is usually more smooth and "rounded" Scents from this note class appear anywhere from two minutes to one hour after the application of a perfume.
The base notes are the scent that appears after the disappearance of the middle notes, the base and middle notes together are the main theme of a perfume. Base notes bring profundity and strength to a perfume, compounds of this class are often the fixatives used to hold and boost the strength of the lighter top and middle notes. Consisting of big, weighty molecules that disperse slowly, compounds of this class of scents are typically rich and "deep" and are usually not apparent until thirty minutes after the application of the perfume or during the period of perfume dry-down. Some base notes can still be detectable in excess of twenty-four hours after application, particularly the animalic notes.
