A salve is a medical ointment used to soothe the skin .
75-603: Magnesium sulphate paste is used as a drawing salve to treat small boils and infected wounds and to remove 'draw' small splinters. Black ointment, or Ichthyol Salve, also called Drawing Salve , has been traditionally used to treat minor skin problems such as sebaceous cysts , boils, ingrown toenails and splinters. The main ingredients are often ichthammol , phenyl alcohol , or Arnica montana , and may contain herbs such as echinacea or calendula . The name comes from archaic belief that an irritant can "draw out" evil humors . (This should not be confused with black salve which

The composition of a perfume typically begins with a brief by the perfumer's employer or an outside customer. The customers to the perfumer or their employers, are typically fashion houses or large corporations of various industries. The perfumer will then go through the process of blending multiple perfume mixtures and sell
225-665: A family of fresh, citrus-based fragrances distilled using extracts from citrus, floral, and woody ingredients. These "classical colognes" were supposedly first developed in Cologne, Germany , hence the name. This type of cologne, which is still in production, describes unisex compositions "which are basically citrus blends and do not have a perfume parent." Examples include Mäurer & Wirtz's 4711 (created in 1799), and Guerlain's Eau de Cologne Impériale (1830). "Toilet water," or eau de toilette, referred to wide range of scented waters not otherwise known as colognes, and were popular throughout
300-403: 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. 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
375-429: A mix of water and ethanol. Various sources differ considerably in the definitions of perfume types. The intensity and longevity of a fragrance is based on the concentration, intensity, and longevity of the aromatic compounds, or perfume oils, used. As the percentage of aromatic compounds increases, so does the intensity and longevity of the scent. Specific terms are used to describe a fragrance's approximate concentration by
450-538: A mixture of ice VI and the enneahydrate MgSO 4 ·9H 2 O . The enneahydrate MgSO 4 ·9H 2 O was identified and characterized only recently, even though it seems easy to produce (by cooling a solution of MgSO 4 and sodium sulfate Na 2 SO 4 in suitable proportions). The structure is monoclinic, with unit-cell parameters at 250 K: a = 0.675 nm , b = 1.195 nm, c = 1.465 nm, β = 95.1°, V = 1.177 nm with Z = 4. The most probable space group
525-411: A more concentrated product, typically a pure parfum, and is usually the lightest concentration from a line of fragrance products. The eau de parfum concentration and terminology is the most recent, being originally developed to offer the radiance of an EdT with the longevity of an extrait. Parfum de toilette and EdP began to appear in the 1970s and gained popularity in the 1980s. In the 21st century, EdP
600-484: A perfume can be constructed from a concept. Although many ingredients do not contribute to the smell of a perfume, many perfumes include colorants and antioxidants to improve the marketability and shelf life of the perfume, respectively. Perfume oils usually contain tens to hundreds of ingredients and these are typically organized in a perfume for the specific role they will play. These ingredients can be roughly grouped into four groups: The top, middle, and base notes of
675-456: 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." Ancient texts and archaeological excavations show
750-425: A single aromatic material. The family classification is a starting point to describe a perfume, but does not fully characterize it. The traditional categories which emerged around 1900: Since 1945, new categories have emerged to describe modern scents, due to great advances in the technology of compound design and synthesis, as well as the natural development of styles and tastes: This newer classification method
825-504: 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 alcohol, 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 and almond oil . The conventional application of pure perfume (parfum extrait) in Western cultures

#1732883693356900-424: 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
975-593: 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 . There is a controversy on whether perfumery was completely lost in Western Europe after the fall of the Western Roman Empire . That said, the art of perfumery in Western Europe
1050-604: A wheel. In this scheme, Chanel No.5 , traditionally classified as an aldehydic floral, is placed under the Soft Floral sub-group, while amber scents are within the Oriental group. Chypre perfumes are more ambiguous, having affinities with both the Oriental and Woody families. For instance, Guerlain Mitsouko is under Mossy Woods, but Hermès Rouge , a more floral chypre, is under Floral Oriental. Plants have long been used in perfumery as
1125-440: A wider range of customers. As this process accelerated, perfume houses borrowed the term "cologne" to refer to an even more diluted interpretation of their fragrances than eau de toilette. Guerlain , for example, offered an eau de cologne version of its flagship perfume Shalimar and many of its other fragrances. In contrast to a classical eau de cologne, this type of modern cologne is a lighter, less concentrated interpretation of
1200-546: Is P21/c. Magnesium selenate also forms an enneahydrate MgSeO 4 ·9H 2 O , but with a different crystal structure. As Mg and SO 2− 4 ions are respectively the second most abundant cation and anion present in seawater after Na and Cl , magnesium sulfates are common minerals in geological environments. Their occurrence is mostly connected with supergene processes. Some of them are also important constituents of evaporitic potassium -magnesium (K-Mg) salts deposits. Bright spots observed by

It is a white crystalline solid , soluble in water but not in ethanol . Magnesium sulfate is usually encountered in the form of a hydrate MgSO 4 · n H 2 O , for various values of n between 1 and 11. The most common
1350-472: Is applied to those sold to men. The actual product worn by a woman may be an eau de parfum rather than an extrait, or by a man an eau de toilette rather than an eau de cologne. The reasons why the terms "perfume" and "cologne" are often used in a generic sense is related to the modern development of perfumery in Europe since the 18th century. The term "cologne" was first used in Europe in the 18th century to refer to
1425-405: Is behind the ears, at the nape of the neck, under the armpits and at 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

Solutions of magnesium sulfate are also nearly pH neutral, compared with the slightly alkaline salts of magnesium as found in limestone ; therefore, the use of magnesium sulfate as a magnesium source for soil does not significantly change the soil pH . Contrary to the popular belief that magnesium sulfate is able to control pests and slugs, helps seeds germination, produce more flowers, improve nutrient uptake, and
1725-447: Is mainly utilized in the production of lightweight insulation panels, although its poor water resistance limits its usage. Magnesium (or sodium) sulfate is also used for testing aggregates for soundness in accordance with ASTM C88 standard, when there are no service records of the material exposed to actual weathering conditions. The test is accomplished by repeated immersion in saturated solutions followed by oven drying to dehydrate
1800-410: Is probably the most widespread strength concentration. It is often the first concentration offered when a new fragrance is launched, and usually referred to generically as "perfume." Historically, women's fragrances tended to have higher levels of aromatic compounds than men's fragrances. Fragrances marketed to men were typically sold as EdT or EdC, rarely as EdP or perfume extracts. This is changing in
1875-490: 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
1950-544: Is slowly depleted in their calcification process. In a magnesium-deficient marine aquarium, calcium and alkalinity concentrations are very difficult to control because not enough magnesium is present to stabilize these ions in the saltwater and prevent their spontaneous precipitation into calcium carbonate . Double salts containing magnesium sulfate exist. There are several known as sodium magnesium sulfates and potassium magnesium sulfates . A mixed copper -magnesium sulfate heptahydrate (Mg,Cu)SO 4 ·7H 2 O

Potential health effects of magnesium sulfate are reflected in medical studies on the impact of magnesium on resistant depression and as an analgesic for migraine and chronic pain . Magnesium sulfate has been studied in
2175-402: Is the heptahydrate MgSO 4 ·7H 2 O , known as Epsom salt , which is a household chemical with many traditional uses, including bath salts . The main use of magnesium sulfate is in agriculture, to correct soils deficient in magnesium (an essential plant nutrient because of the role of magnesium in chlorophyll and photosynthesis ). The monohydrate is favored for this use; by
2250-545: Is the next lower hydrate. Three next lower hydrates – pentahydrite , starkeyite , and especially sanderite – are rare. Kieserite is a monohydrate and is common among evaporitic deposits. Anhydrous magnesium sulfate was reported from some burning coal dumps . Magnesium sulfate is usually obtained directly from dry lake beds and other natural sources. It can also be prepared by reacting magnesite ( magnesium carbonate , MgCO 3 ) or magnesia ( oxide , MgO) with sulfuric acid ( H 2 SO 4 ): Another possible method
2325-446: Is the primary mechanism that causes the absorption of sound in seawater at frequencies above 10 kHz ( acoustic energy is converted to thermal energy ). Lower frequencies are less absorbed by the salt, so that low frequency sound travels farther in the ocean. Boric acid and magnesium carbonate also contribute to absorption. Magnesium sulfate is used both externally (as Epsom salt) and internally. The main external use

Other inorganic sulfate salts such as sodium sulfate and calcium sulfate may be used in the same way. Magnesium sulfate is used to prepare specific cements by the reaction between magnesium oxide and magnesium sulfate solution, which are of good binding ability and more resistance than Portland cement . This cement
2625-440: 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

Thanks to Rene, France quickly became one of the European centers of perfume and cosmetics manufacture. Cultivation of flowers for their perfume essence, which had begun in
3225-440: The 19th century. The term "perfume" emerged in the late 19th century. The first fragrance labeled a "parfum" extract with a high concentration of aromatic compounds was Guerlain's Jicky in 1889. In the first half of the 20th century, fragrance companies began offering their products in more than one concentration, often pairing an extrait with a lighter eau de toilette suitable for day wear, which made their products available to

Orange leaves, blossoms, and fruit zest are the respective sources of petitgrain , neroli , and orange oils . 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
3450-616: The anhydrous form is stable. It decomposes without melting at 1124 °C into magnesium oxide (MgO) and sulfur trioxide ( SO 3 ). The heptahydrate takes its common name "Epsom salt" from a bitter saline spring in Epsom in Surrey , England, where the salt was produced from the springs that arise where the porous chalk of the North Downs meets the impervious London clay . The heptahydrate readily loses one equivalent of water to form
3525-572: The aromatic compounds, which either change their odor character or renders them odorless. Although fragrant extracts are known to the general public as the generic term " essential oils ", a more specific language is used in the fragrance industry to describe the source, purity, and technique used to obtain a particular fragrant extract. Of these extracts, only absolutes , essential oils , and tinctures are directly used to formulate perfumes. Products from different extraction methods are known under different names even though their starting materials are
3600-681: The art of making perfumes, began in ancient Mesopotamia , Egypt , the Indus Valley civilization and possibly Ancient China . It was further refined by the Romans and the Muslims. One of the world's first-recorded chemists is considered to be 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
3675-512: The business in 1732. By the 18th century the Grasse region of France, Sicily , and Calabria (in Italy) were growing aromatic plants to provide the growing perfume industry with raw materials. Even today, Italy and France remain the center of European perfume design and trade . Perfume types reflect the concentration of aromatic compounds in a solvent, which in fine fragrance is typically ethanol or

Therefore, although the oil concentration of a perfume in EdP dilution will necessarily be higher than the same perfume in EdT from within a company's same range, the actual amount will vary among companies. An EdT from one house may have a higher concentration of aromatic compounds than an EdP from another. Furthermore, some fragrances with

The grouping of perfumes can never be completely objective or definitive. Many fragrances contain aspects of different families. Even a perfume designated as "single flower" will have subtle undertones of other aromatics. There are hardly any true unitary-scent perfumes consisting of
3975-532: The fragrant compounds found in various orchids. One of the most commonly used classes of synthetic aromatics by far are the white musks . These materials are found in all forms of commercial perfumes as a neutral background to the middle notes. These musks are added in large quantities to laundry detergents in order to give washed clothes a lasting "clean" scent. The majority of the world's synthetic aromatics are created by relatively few companies . They include: Each of these companies patents several processes for
4050-683: The hexahydrate. It is a natural source of both magnesium and sulphur . Epsom salts are commonly used in bath salts , exfoliants , muscle relaxers and pain relievers. However, these are different from Epsom salts that are used for gardening, as they contain aromas and perfumes not suitable for plants. Magnesium sulfate monohydrate, or kieserite, can be prepared by heating the heptahydrate to 120 °C. Further heating to 250 °C gives anhydrous magnesium sulfate. Kieserite exhibits monoclinic symmetry at pressures lower than 2.7 GPa after which it transforms to phase of triclinic symmetry. The undecahydrate MgSO 4 ·11H 2 O , meridianiite ,

Recipes of perfumes from the monks of Santa Maria Delle Vigne or Santa Maria Novella of Florence , Italy, were recorded from 1221. In the east, the Hungarians produced around 1370 a perfume made of scented oils blended in an alcohol solution – best known as Hungary Water – at the behest of Queen Elizabeth of Hungary . The art of perfumery prospered in Renaissance Italy, and in

These notes are created carefully with knowledge of the evaporation process of the perfume. The scents in the top and middle notes are influenced by the base notes; conversely, the scents of the base notes will be altered by the types of fragrance materials used as middle notes. Manufacturers who publish perfume notes typically do so with

For instance, in order to make the EdT version of a fragrance brighter and fresher than its EdP, the EdT oil may be "tweaked" to contain slightly more top notes or fewer base notes. Chanel No. 5 is a good example: its parfum, EdP, EdT, and now-discontinued EdC concentrations are in fact different compositions (the parfum dates to 1921,

In 2003, archaeologists uncovered what are believed to be the world's oldest surviving perfumes in Pyrgos , Cyprus . The perfumes dated back more than 4,000 years. They were discovered in an ancient perfumery, a 300-square-meter (3,230 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 May 2018, an ancient perfume "Rodo" (Rose)

5325-459: 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. The word perfume is derived from the Latin perfumare , meaning "to smoke through". Perfumery, as

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. 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
