Perfume is a mixture of fragrant essential oils or aroma compounds (fragrances), fixatives and solvents, usually in liquid form, used to give the human body, animals, food, objects, and living-spaces an agreeable scent. Perfumes can be defined as substances that emit and diffuse a pleasant and fragrant odor. They consist of manmade mixtures of aromatic chemicals and essential oils. The 1939 Nobel Laureate for Chemistry, Leopold Ružička stated in 1945 that "right from the earliest days of scientific chemistry up to the present time, perfumes have substantially contributed to the development of organic chemistry as regards methods, systematic classification, and theory."
The Coca-Cola Company's formula for Coca-Cola syrup, which bottlers combine with carbonated water to create the company's flagship cola soft drink, is a closely guarded trade secret. Company founder Asa Candler initiated the veil of secrecy that surrounds the formula in 1891 as a publicity, marketing, and intellectual property protection strategy. While several recipes, each purporting to be the authentic formula, have been published, the company maintains that the actual formula remains a secret, known only to a very few select, and anonymous, employees. The claim that the recipe is only known to two people and that they cannot fly on the same plane due to the chance they may die, and the recipe will become unknown, is a myth and has been fact-checked multiple times.
An essential oil is a concentrated hydrophobic liquid containing volatile chemical compounds from plants. Essential oils are also known as volatile oils, ethereal oils, aetheroleum, or simply as the oil of the plant from which they were extracted, such as oil of clove. An essential oil is essential in the sense that it contains the essence of the plant's fragrance—the characteristic fragrance of the plant from which it is derived. The term "essential" used here does not mean required or usable by the human body, as with the terms essential amino acid or essential fatty acid, which are so called because they are nutritionally required by a living organism.
The bitter orange, sour orange, Seville orange, bigarade orange, or marmalade orange is the hybrid citrus tree species Citrus × aurantium, and its fruit. It is native to Southeast Asia and has been spread by humans to many parts of the world. It is a cross between the pomelo, Citrus maxima, and the wild type mandarin orange, Citrus reticulata. The bitter orange is used to make essential oil, used in foods, drinks, and pharmaceuticals. The Seville orange is prized for making British orange marmalade.
Cananga odorata, known as ylang-ylang or cananga tree, is a tropical tree that is native to the Philippines, Malaysia, Indonesia, New Guinea, the Solomon Islands, and Queensland, Australia. It is also native to parts of Thailand and Vietnam. It is valued for the essential oils extracted from its flowers, which has a strong floral fragrance. Ylang-ylang is one of the most extensively used natural materials in the perfume industry, earning it the name "Queen of Perfumes".
Linalool refers to two enantiomers of a naturally occurring terpene alcohol found in many flowers and spice plants. Together with geraniol, nerol, citronellol, linalool is one of the rose alcohols. Linalool has multiple commercial applications, the majority of which are based on its pleasant scent.
Citrus bergamia, the bergamot orange, is a fragrant citrus fruit the size of an orange, with a yellow or green colour similar to a lime, depending on ripeness.
Nutmeg oil is a volatile essential oil from nutmeg. The oil is colorless or light yellow and smells and tastes of nutmeg. It contains numerous components of interest to the oleochemical industry. The essential oil consists of approximately 90% terpene hydrocarbons. Prominent components are sabinene, α-pinene, β-pinene, and limonene. A major oxygen-containing component is terpinen-4-ol. The oil also contains small amounts of various phenolic compounds and aromatic ethers, e.g. myristicin, elemicin, safrole, and methyl eugenol. The phenolic fraction is considered main contributor to the characteristic nutmeg odor. However, in spite of the low oil content, the characteristic composition of nutmeg oil makes it a valuable product for food, cosmetic and pharmaceutical industries. Therefore, an improved process for its extraction would be of industrial interest.
Limonene is a colorless liquid aliphatic hydrocarbon classified as a cyclic monoterpene, and is the major component in the essential oil of citrus fruit peels. The (+)-isomer, occurring more commonly in nature as the fragrance of oranges, is a flavoring agent in food manufacturing. It is also used in chemical synthesis as a precursor to carvone and as a renewables-based solvent in cleaning products. The less common (-)-isomer has a piny, turpentine-like odor, and is found in the edible parts of such plants as caraway, dill, and bergamot orange plants.
Rose oil is an essential oil that is extracted from the petals of various types of rose. Rose ottos are extracted through steam distillation, while rose absolutes are obtained through solvent extraction, the absolute being used more commonly in perfumery. The production technique originated in Greater Iran. Even with their high price and the advent of organic synthesis, rose oils are still perhaps the most widely used essential oil in perfumery.
Orange oil is an essential oil produced by cells within the rind of an orange fruit. In contrast to most essential oils, it is extracted as a by-product of orange juice production by centrifugation, producing a cold-pressed oil. It is composed of mostly d-limonene, and is often used in place of pure d-limonene. D-limonene can be extracted from the oil by distillation.
Fragrance extraction refers to the separation process of aromatic compounds from raw materials, using methods such as distillation, solvent extraction, expression, sieving, or enfleurage. The results of the extracts are either essential oils, absolutes, concretes, or butters, depending on the amount of waxes in the extracted product.
Geranyl acetate is a terpenoid. It is a colorless liquid with a pleasant floral or fruity rose aroma. It is a colorless liquid but commercial samples can appear yellowish. Geranyl acetate is insoluble in water but soluble in organic solvents. Several hundred tons are produced annually.
Chypre is the name of a family of perfumes that are characterised by an accord composed of citrus top notes, a middle centered on cistus labdanum, and a mossy-animalic set of basenotes derived from oakmoss. Chypre perfumes fall into numerous classes according to their modifier notes, which include but are not limited to leather, florals, fruits, and amber.
The word perfume is used today to describe scented mixtures and is derived from the Latin word per fumus. The word perfumery refers to the art of making perfumes. Perfume was produced by ancient Greeks, and perfume was also refined by the Romans, the Persians and the Arabs. Although perfume and perfumery also existed in East Asia, much of its fragrances were incense based. The basic ingredients and methods of making perfumes are described by Pliny the Elder in his Naturalis Historia.
Methyl anthranilate, also known as MA, methyl 2-aminobenzoate, or carbomethoxyaniline, is an ester of anthranilic acid. Its chemical formula is C8H9NO2. It has a strong and fruity grape smell, and one of its key uses is as a flavoring agent.
Eau de toilette is a lightly scented perfume. It is also referred to as aromatic waters and has a high alcohol content. It is usually applied directly to the skin after bathing or shaving. It is traditionally composed of alcohol and various volatile oils. Traditionally these products were named after a principal ingredient, like geranium water, lavender water, lilac water, violet water, spirit of myrcia and "eau de Bretfeld". Because of this, eau de toilette was sometimes referred to as "toilet water".
Petitgrain is an essential oil that is extracted from the leaves and green twigs of the bitter orange tree via steam distillation. It is also known as petitgrain bigarade.
Bergamot essential oil is a cold-pressed essential oil produced by cells inside the rind of a bergamot orange fruit. It is a common flavouring and top note in perfumes. The scent of bergamot essential oil is similar to a sweet light orange peel oil with a floral note.
