Sillage (perfume)
Sillage (, ) in perfume refers to the trail created by a perfume when it is worn on the skin. It comes from the word in French for "wake" and can best be described as how a fragrance diffuses behind the wearer as they move. A fragrance does not need to be a heavy one to have a large sillage. Sillage in a perfume is not to be confused with its 'projection' (how a fragrance is perceived by others around the wearer) and is enhanced by motion, ambient temperature as well as the inherent qualities of the skin. According to an article by Mookerjee, a fragrance is perceived by the diffusion of individual fragrance molecules. The rate of diffusion of these molecules in a fragrance, however, appears to be independent of their molecular weights, boiling points, odour thresholds and odour value. Once a fragrance is applied to the skin, the skin itself becomes a substrate to the scent. The inherent scent of the individual skin, moisturisation of the skin, the behaviour of the microbiome of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lexico
Lexico was a dictionary website that provided a collection of English and Spanish dictionaries produced by Oxford University Press (OUP), the publishing house of the University of Oxford. While the dictionary content on Lexico came from OUP, this website was operated by Dictionary.com, whose eponymous website hosts dictionaries by other publishers such as Random House. The website was closed and redirected to Dictionary.com on 26 August 2022. Before the Lexico site was launched, the ''Oxford Dictionary of English'' and ''New Oxford American Dictionary'' were hosted by OUP's own website Oxford Dictionaries Online (ODO), later known as Oxford Living Dictionaries. The dictionaries' definitions have also appeared in Google Dictionary, Google definition search and the Dictionary (software), Dictionary application on macOS, among others, licensed through the Oxford Dictionaries application programming interface, API.

Oxford University Press
Oxford University Press (OUP) is the university press of the University of Oxford. It is the largest university press in the world, and its printing history dates back to the 1480s. Having been officially granted the legal right to print books by decree in 1586, it is the second oldest university press after Cambridge University Press. It is a department of the University of Oxford and is governed by a group of 15 academics known as the Delegates of the Press, who are appointed by the vice-chancellor of the University of Oxford. The Delegates of the Press are led by the Secretary to the Delegates, who serves as OUP's chief executive and as its major representative on other university bodies. Oxford University Press has had a similar governance structure since the 17th century. The press is located on Walton Street, Oxford, opposite Somerville College, in the inner suburb of Jericho. For the last 500 years, OUP has primarily focused on the publication of pedagogical texts a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perfume
Perfume (, ; french: parfum) 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. 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." 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. History The word ''perfume'' derives from the Latin ''perfumare'', meaning "to smoke through ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Damascone
Damascones are a series of closely related chemical compounds that are components of a variety of essential oils. The damascones belong to a family of chemicals known as rose ketones, which also includes damascenones and ionones. ''beta''-Damascone is a contributor to the aroma of roses, despite its relatively low concentration, and is an important fragrance chemical used in perfumery. The damascones are derived from the degradation of carotenoids.Volatile Compounds Released by Enzymatic Hydrolysis of Glycoconjugates of Leaves and Grape Berries from Vitis vinifera Muscat of Alexandria and Shiraz Cultivars.

Linalool
Linalool () refers to two enantiomers of a naturally occurring terpene alcohol found in many flowers and spice plants. Linalool has multiple commercial applications, the majority of which are based on its pleasant scent (floral, with a touch of spiciness). A colorless oil, linalool is classified as an acyclic monoterpenoid. In plants, it is a metabolite, a volatile oil component, an antimicrobial agent, and an aroma compound. Linalool has uses in manufacturing of soaps, fragrances, food additives as flavors, household products, and insecticides. Esters of linalool are referred to as linalyl, e.g. linalyl pyrophosphate, an isomer of geranyl pyrophosphate. The word ''linalool'' is based on ''linaloe'' (a type of wood) and the suffix '. In food manufacturing, it may be called ''coriandrol''. Occurrence Both enantiomeric forms are found in nature: (''S'')-linalool is found, for example, as a major constituent of the essential oils of coriander ('' Coriandrum sativum'' L.) ...

Cashmeran
Cashmeran (trade name; also known as musk indanone or indomuscone; chemical name 6,7-dihydro-1,1,2,3,3-pentamethyl-4(5''H'')-indanone or DPMI) is a chemical compound used in fragrances. Physical-chemical properties Cashmeran is an alicyclic ketone with the molecular formula C14H22O and a molecular weight of 206 g/mol. At room temperature it occurs as a white solid but its melting point is 27 °C. Boiling point has been reported to be 256 °C, however in some tests decomposition of the material was noted at 220 °C. History Cashmeran was discovered by International Flavors and Fragrances in the 1970s by John Hall. Its invention came about researching inexpensive chemical transformations from ingredients from the pentamethyl indane and tetramethyl naphthalene structures. As a result, Cashmeran, an unsaturated ketone, was identified as an important new fragrance ingredient. Odour Although cashmeran has been described by some as a polycyclic musk, it is neither ...

Methyl Jasmonate
Methyl jasmonate (abbreviated MeJA) is a volatile organic compound used in plant defense and many diverse developmental pathways such as seed germination, root growth, flowering, fruit ripening, and senescence. Methyl jasmonate is derived from jasmonic acid and the reaction is catalyzed by ''S''-adenosyl--methionine:jasmonic acid carboxyl methyltransferase. Description Plants produce jasmonic acid and methyl jasmonate in response to many biotic and abiotic stresses (in particular, herbivory and wounding), which build up in the damaged parts of the plant. The methyl jasmonate can be used to signal the original plant’s defense systems or it can be spread by physical contact or through the air to produce a defensive reaction in unharmed plants. The unharmed plants absorb the airborne MeJA through either the stomata or diffusion through the leaf cell cytoplasm. An herbivorous attack on a plant causes it to produce MeJA both for internal defense and for a signaling compound to o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jasmine
Jasmine ( taxonomic name: ''Jasminum''; , ) is a genus of shrubs and vines in the olive family ( Oleaceae). It contains around 200 species native to tropical and warm temperate regions of Eurasia, Africa, and Oceania. Jasmines are widely cultivated for the characteristic fragrance of their flowers. A number of unrelated plants contain the word "jasmine" in their common names (see Other plants called "jasmine").
