PERFUME


Perfume is made up of alcohol, water & perfume (fragrance) oil.

It is a word that comes from Latin per fumum, which means "through smoke" (per means through, fumum means smoke).

There are 3 major types: oriental, floral & chypre (means "very sincere" in French). There are also many sub-variations such as woody, musky, aquatic, spicy & fruity.

perfume aroma produced by the essential oils of plants and by synthetic aromatics. The burning of incense that accompanied the religious rites of ancient China, Palestine, and Egypt led gradually to the personal use of perfume. In Greece, where flower scents were first developed, the use of perfume became widespread. In Rome perfume was used extravagantly. During the Middle Ages the Crusaders brought the knowledge of perfumery back to Europe from the East. It was at this time that animal substances were first added as fixatives— musk , ambergris , civet , and castoreum (from the beaver ). Italian perfumers settled in Paris (after 1500), and thereafter France became the leader of the industry. After 1500 scents became fashionable; both men and women wore an ornamental pomander or pouncet-box (dry-scent box), which hung from the waist. Each wealthy household had a "still

History

The word perfume used today derives from the Latin "per fumum", meaning through smoke. Perfumery, or the art of making perfumes, began in ancient Mesopotamia and Egypt and was further refined by the Romans and Persians. Although perfume and perfumery also existed in India, much of its fragrances are incense based. The earliest distillation of Attar was mentioned in the Hindu Ayurvedic text Charaka Samhita. The Harshacharita, written in 7th century A.D. in Northern India mentions use of fragrant agarwood oil.

The world's first recorded chemist is considered to be a woman named Tapputi, a perfume maker who was mentioned in a cuneiform tablet from the second millennium BC in Mesopotamia.[1] She distilled flowers, oil, and calamus with other aromatics then filtered and put them back in the still several times.[2]

Recently, archaeologists have uncovered what are believed to be the world's oldest perfumes in Pyrgos, Cyprus. The perfumes date back more than 4,000 years. The perfumes were discovered in an ancient perfumery. At least 60 stills, mixing bowls, funnels and perfume bottles were found in the 43,000-square-foot (4,000 m2) factory.[3] In ancient times people used herbs and spices, like almond, coriander, myrtle, conifer resin, bergamot, as well as flowers.[4]

The Arabian chemist, Al-Kindi (Alkindus), wrote in the 9th century a book on perfumes which he named Book of the Chemistry of Perfume and Distillations. It contained more than a hundred recipes for fragrant oils, salves, aromatic waters and substitutes or imitations of costly drugs. The book also described 107 methods and recipes for perfume-making, and even the perfume making equipment, like the alembic, still bears its Arabic name[5].

The Persian Muslim doctor and chemist Avicenna (also known as Ibn Sina) introduced the process of extracting oils from flowers by means of distillation, the procedure most commonly used today. He first experimented with the rose. Until his discovery, liquid perfumes were mixtures of oil and crushed herbs or petals, which made a strong blend. Rose water was more delicate, and immediately became popular. Both of the raw ingredients and distillation technology significantly influenced western perfumery and scientific developments, particularly chemistry.

Knowledge of perfumery came to Europe as early as the 14th century due partially to the spread of Islam. But it was the Hungarians who ultimately introduced the first modern perfume. Made of scented oils blended in an alcohol solution, the first modern perfume was made in 1370 at the command of Queen Elizabeth of Hungary and was known throughout Europe as Hungary Water. The art of perfumery prospered in Renaissance Italy, and in the 16th century, Italian refinements were taken to France by Catherine de' Medici's personal perfumer, Rene le Florentin. His laboratory was connected with her apartments by a secret passageway, so that no formulas could be stolen en route. France quickly became the European center of perfume and cosmetic manufacture. Cultivation of flowers for their perfume essence, which had begun in the 14th century, grew into a major industry in the south of France. During the Renaissance period, perfumes were used primarily by the wealthy to mask body odors resulting from infrequent bathing. Partly due to this patronage, the western perfumery industry was created. By the 18th century, aromatic plants were being grown in the Grasse region of France to provide the growing perfume industry with raw materials. Even today, France remains the centre of the European perfume design and trade.


Describing a perfume

The precise formulae of commercial perfumes are kept secret. Even if they were widely published, they would be dominated by such complex ingredients and odorants that they would be of little use in providing a guide to the general consumer in description of the experience of a scent. Nonetheless, connoisseurs of perfume can become extremely skillful at identifying components and origins of scents in the same manner as wine experts [6].

The most practical way to start describing a perfume is according to the elements of the fragrance notes of the scent or the family it belongs to, all of which affect the overall impression of a perfume from first application to the last lingering hint of scent.

Fragrance notes

Perfume is described in a musical metaphor as having three sets of 'notes', making the harmonious scent accord. The notes unfold over time, with the immediate impression of the top note leading to the deeper middle notes, and the base notes gradually appearing as the final stage. These notes are created carefully with knowledge of the evaporation process of the perfume.

  • Top notes: The scents that are perceived immediately on application of a perfume. Top notes consist of small, light molecules that evaporate quickly. They form a person's initial impression of a perfume and thus are very important in the selling of a perfume. Also called the head notes.
  • Middle notes: The scent of a perfume that emerges just prior to when the top notes dissipate. The middle note compounds form the "heart" or main body of a perfume and act to mask the often unpleasant initial impression of base notes, which become more pleasant with time. They are also called the "heart notes".
  • Base notes: The scent of a perfume that appears close to the departure of the middle notes. The base and middle notes together are the main theme of a perfume. Base notes bring depth and solidity to a perfume. Compounds of this class of scents are typically rich and "deep" and are usually not perceived until 30 minutes after application.

The scents in the top and middle notes are influenced by the base notes, as well the scents of the base notes will be altered by the type of fragrance materials used as middle notes. Manufacturers of perfumes usually publish perfume notes and typically they present it as fragrance pyramid, with the components listed in imaginative and abstract terms.

Olfactive families

Grouping perfumes, like any taxonomy, can never be a completely objective or final process. Many fragrances contain aspects of different families. Even a perfume designated as "single flower", however subtle, will have undertones of other aromatics. "True" unitary scents can rarely be found in perfumes as it requires the perfume to exist only as a singular aromatic material.

Classification by olfactive family is a starting point for a description of a perfume, but it cannot by itself denote the specific characteristic of that perfume. Traditional

The traditional classification which emerged around 1900 comprised the following categories:

  • Single Floral: Fragrances that are dominated by a scent from one particular flower; in French called a soliflore. (e.g. Serge Lutens' Sa Majeste La Rose, which is dominated by rose.)
  • Floral Bouquet: Containing the combination of several flowers in a scent.
  • Amber: A large fragrance class featuring the sweet slightly animalic scents of ambergris or labdanum, often combined with vanilla, flowers and woods. Can be enhanced by camphorous oils and incense resins, which bring to mind Victorian era imagery of the Middle East and Far East.
  • Wood: Fragrances that are dominated by woody scents, typically of agarwood, sandalwood and cedar. Patchouli, with its camphoraceous smell, is commonly found in these perfumes.
  • 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: Meaning Cyprus in French, this includes fragrances built on a similar accord consisting of bergamot, oakmoss, patchouli, and labdanum. This family of fragrances is named after a perfume by François Coty. A notable example is Mitsouko (a popular name for girls in Japanese) by Guerlain.
  • Fougère: Meaning Fern in French, built on a base of lavender, coumarin and oakmoss. Houbigant's Fougère Royale pioneered the use of this base. Many men's fragrances belong to this family of fragrances, which is characterized by its sharp herbaceous and woody scent.

Modern

Since 1945, due to great advances in the technology of perfume creation (i.e., compound design and synthesis) as well as 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 interpretation of the Chypre type, with pronounced cut grass and cucumber-like scents
  • Aquatic, Oceanic, or Ozonic: the newest category in perfume history, appearing in 1991 with Christian Dior's Dune. A very clean, modern smell leading to many of the modern androgynous perfumes. Generally contains calone, a synthetic scent discovered in 1966. Also used to accent floral, oriental, and woody fragrances.
  • Citrus: 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.
  • Fruity: featuring the aromas of fruits other than citrus, such as peach, cassis (black currant), mango, passion fruit, and others.
  • Gourmand: scents with "edible" or "dessert"-like qualities. These often contain notes like vanilla, tonka bean and coumarin, as well as synthetic components designed to resemble food flavors. An example is Thierry Mugler's Angel.

Fragrance wheel

The Fragrance wheel is a relatively new classification method that is widely used in retail and in the fragrance industry. The method was created in 1983 by Michael Edwards, a consultant in the perfume industry, who designed his own scheme of fragrance classification.The new scheme was created in order to simplify fragrance classification and naming scheme, as well as to show the relationships between each of the individual classes[9].

The five standard families consist of Floral, Oriental, Woody, Fougère, and Fresh, with the former four families being more "classic" while the latter consisting of newer bright and clean smelling citrus and oceanic fragrances that have arrived due to improvements in fragrance technology. Each of the families are in turn divided into sub-groups and arranged around a wheel.

Aromatics sources


Plant sources

Plants have long been used in perfumery as a source of essential oils and aroma compounds. These aromatics are usually secondary metabolites produced by plants as protection against herbivores, infections, as well as to attract pollinators. Plants are by far the largest source of fragrant compounds used in perfumery. The sources of these compounds may be derived from various parts of a plant. A plant can offer more than one source of aromatics, for instance the aerial portions and seeds of coriander have remarkably different odors from each other. Orange leaves, blossoms, and fruit zest are the respective sources of petitgrain, neroli, and orange oils.

Animal sources

  • Ambergris: Lumps of oxidized fatty compounds, whose precursors were secreted and expelled by the Sperm Whale. Ambergris is commonly referred to as "amber" in perfumery and should not be confused with yellow amber, which is used in jewelry.
  • Castoreum: Obtained from the odorous sacs of the North American beaver.
  • Civet: Also called Civet Musk, this is obtained from the odorous sacs of the civets, animals in the family Viverridae, related to the Mongoose. The World Society for the Protection of Animals investigated African civets caught for this purpose.[11]
  • Hyraceum: Commonly known as "Africa Stone," is the petrified excrement of the Rock Hyrax.[12]
  • Honeycomb: From the honeycomb of the Honeybee. Both beeswax and honey can be solvent extracted to produce an absolute. Beeswax is extracted with ethanol and the ethanol evaporated to produce beeswax absolute.
  • Musk: Originally derived from the musk sacs from the Asian musk deer, it has now been replaced by the use of synthetic musks sometimes known as “white musk”.

Other natural sources

  • Lichens: Commonly used lichens include oakmoss and treemoss thalli.
  • "Seaweed": Distillates are sometimes used as essential oil in perfumes. An example of a commonly used seaweed is Fucus vesiculosus, which is commonly referred to as bladder wrack. Natural seaweed f

    Synthetic sources


    Many modern perfumes contain synthesized odorants. Synthetics can provide fragrances which are not found in nature. For instance, Calone, a compound of synthetic origin, imparts a fresh ozonous metallic marine scent that is widely used in contemporary perfumes. Synthetic aromatics are often used as an alternate source of compounds that are not easily obtained from natural sources. For example, linalool and coumarin are both naturally occurring compounds that can be inexpensively synthesized from terpenes. Orchid scents (typically salicylates) are usually not obtained directly from the plant itself but are instead synthetically created to match the fragrant compounds found in various orchids.

    The majority of the world's synthetic aromatics are created by relatively few companies. They include:

  • International Flavors and Fragrances (IFF)
  • Givaudan
  • Firmenich
  • Takasago
  • Symrise

Each of these companies patents several processes for the production of aromatic synthetics annually.
