Perfume

Perfume, is a mixture of fragrant essential oils or aroma compounds, fixatives and solvents - used to give the human body, animals, food, objects, and living-spaces "a pleasant scent".

Ancient texts and archaeological excavations show the use of perfumes in some of the earliest human civilizations. Modern perfumery began in the late 19th century with the commercial synthesis of aroma compounds such as vanillin or coumarin, which allowed for the composition of perfumes with smells previously unattainable solely from natural aromatics alone.

The word perfume derives from the Latin perfumare, meaning "to smoke through". Perfumery, as the art of making perfumes, began in ancient Mesopotamia and Egypt, and was further refined by the Romans and Persians.

The world's first-recorded chemist is considered a woman named Tapputi, a perfume maker mentioned in a cuneiform tablet from the 2nd millennium BC in Mesopotamia. She distilled flowers, oil, and calamus with other aromatics, then filtered and put them back in the still several times. In India, perfume and perfumery existed in the Indus civilization (3300 BC – 1300 BC). One of the earliest distillations of Ittar was mentioned in the Hindu Ayurvedic text Charaka Samhita and Sushruta Samhita.

In 2004 – 2005, archaeologists uncovered what are believed to be the world's oldest surviving perfumes in Pyrgos, Cyprus. The perfumes date back more than 4,000 years. They were discovered in an ancient perfumery, a 4,000-square-meter (43,000 sq ft) factory housing at least 60 stills, mixing bowls, funnels, and perfume bottles. In ancient times people used herbs and spices, such as almond, coriander, myrtle, conifer resin, and bergamot, as well as flowers.

In the 9th century the Arab chemist Al-Kindi (Alkindus) wrote the Book of the Chemistry of Perfume and Distillations, which 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 perfume-making equipment, such as the alembic (which still bears its Arabic name.from Greek ἄμβιξ, "cup", "beaker" described by Synesius in the 4th century.

The Persian chemist Ibn Sina (also known as Avicenna) 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 consisted of mixtures of oil and crushed herbs or petals, which made a strong blend. Rose water was more delicate, and immediately became popular. Both the raw ingredients and the distillation technology significantly influenced western perfumery and scientific developments, particularly chemistry.

Perfume oils are often diluted with a solvent, though this is not always the case, and its necessity is disputed. By far the most common solvent for perfume oil dilution is an alcohol solution typically a mixture of ethanol and water or a rectified spirit. Perfume oil can also be diluted by means of neutral-smelling oils such as fractionated coconut oil, or liquid waxes such as jojoba oil.

The conventional application of pure perfume (parfum extrait) in Western cultures is at pulse points, such as behind the ears, the nape of the neck, and the insides of wrists, elbows and knees, so that the pulse point will warm the perfume and release fragrance continuously. According to perfumer Sophia Grojsman behind the knees is the ideal point to apply perfume in order that the scent may rise. The modern perfume industry encourages the practice of layering fragrance so that it is released in different intensities depending upon the time of the day. Lightly scented products such as bath oil, shower gel, and body lotion are recommended for the morning; eau de toilette is suggested for the afternoon; and perfume applied to the pulse points for evening. Cologne fragrance is released rapidly, lasting around 2 hours. Eau de toilette lasts from 2 to 4 hours, while perfume may last up to Six hours.

A variety of factors can influence how fragrance interacts with the wearer's own physiology and affect the perception of the fragrance. Diet is one factor, as eating spicy and fatty foods can increase the intensity of a fragrance. The use of medications can also impact the character of a fragrance. The relative dryness of the wearer's skin is important, since dry skin will not hold fragrance as long as skin with more oil.

Grouping perfumes 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.


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: Is a combination of fragrance of several flowers in a perfume compound. Examples include Quelques Fleurs by Houbigant and Joy by Jean Patou.
Amber or "Oriental": A large fragrance class featuring the sweet slightly animalic scents of ambergris or labdanum, often combined with vanilla, tonka bean, 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. Traditional examples include Guerlain's Shalimar, Yves Saint Laurent's Opium and Chanel's Coco Mademoiselle.
Woody: Fragrances that are dominated by woody scents, typically of agarwood, sandalwood, cedarwood, and vetiver. Patchouli, with its camphoraceous smell, is commonly found in these perfumes. A traditional example here would be Myrurgia's Maderas De Oriente or Chanel Bois des Îles. A modern example would be Balenciaga Rumba.
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. Traditional examples include Robert Piguet's Bandit and Balmain's Jolie Madame.
Chypre : Meaning Cyprus in French, this includes fragrances built on a similar accord consisting of bergamot, oakmoss, and labdanum. This family of fragrances is named after the eponymous 1917 perfume by François Coty, and one of the most famous extant examples is Guerlain's Mitsouko.
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. Some well-known modern fougères are Fabergé Brut and Guy Laroche Drakkar Noir.

Perfume compositions are an important part of many industries ranging from the luxury goods sectors, food services industries, to manufacturers of various household chemicals. The purpose of using perfume or fragrance compositions in these industries is to affect customers through their sense of smell and entice them into purchasing the perfume or perfumed product. As such there is significant interest in producing a perfume formulation that people will find aesthetically pleasing.

The perfume industry in the US is not directly regulated by the FDA, instead the FDA controls the safety of perfumes through their ingredients and requires that they be tested to the extent that they are Generally recognized as safe (GRAS). Due to the need for protection of trade secrets, companies rarely give the full listing of ingredients regardless of their effects on health. In Europe, as from 11 March 2005, the mandatory listing of a set of 26 recognized fragrance allergens was enforced.The requirement to list these materials is dependent on the intended use of the final product. The limits above which the allegens are required to be declared are 0.001% for products intended to remain on the skin, and 0.01% for those intended to be rinsed off. This has resulted in many old perfumes like chypres and fougère classes, which require the use of oakmoss extract, being reformulated.
