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.

. Like in the ancient world, Andalusians used fragrance in devotion to God. Perfumes added a layer of cleanliness that was needed for their devotion. Andalusian women were also offered greater freedoms than women in other Muslim controlled regions and were allowed to leave their homes and socialize outside. This freedom allowed courtship to occur outside of the home. As a result, Andalusian women used perfumes for courtship. 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.

Dilution classes

Perfume types reflect the concentration of aromatic compounds in a solvent, which in fine fragrance is typically ethanol or a mix of water and ethanol. Various sources differ considerably in the definitions of perfume types. The intensity and longevity of a perfume 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 the percent of perfume oil in the volume of the final product. The most widespread terms are: * parfum or extrait, in English known as perfume extract, pure perfume, or simply perfume: 15–40% aromatic compounds ( IFRA: typically ~20%); * esprit de parfum (ESdP): 15–30% aromatic compounds, a seldom used strength concentration in between EdP and perfume; * eau de parfum (EdP) or parfum de toilette (PdT): 10–20% aromatic compounds (typically ~15%); sometimes called "eau de perfume" or "millésime." Parfum de toilette is a less common term, most popular in the 1980s, that is generally analogous to eau de parfum. * eau de toilette (EdT): 5–15% aromatic compounds (typically ~10%); This is the staple for most masculine perfumes. * eau de Cologne (EdC): 3–8% aromatic compounds (typically ~5%). This concentration is often simply called cologne; see below for more information on the confusing nature of the term. * eau fraîche: products sold as "splashes", "mists", "veils" and other imprecise terms. Generally these products contain 3% or less aromatic compounds and are diluted with water rather than oil or alcohol. There is much confusion over the term "cologne", which has three meanings. The first and oldest definition refers to a family of fresh, citrus-based fragrances distilled using extracts from citrus, floral, and woody ingredients. Supposedly these were first developed in the early 18th century in Cologne, Germany, hence the name. This type of "classical cologne" describes unisex compositions "which are basically citrus blends and do not have a perfume parent." Examples include Mäurer & Wirtz's ''

'' (created in 1799), and Guerlain's ''Eau de Cologne Impériale'' (1853). In the 20th century, the term took on a second meaning. Fragrance companies began to offer lighter, less concentrated interpretations of their existing perfumes, making their products available to a wider range of customers. Guerlain, for example, offered an eau de Cologne version of its flagship perfume ''

''. In contrast to classical colognes, this type of modern cologne is a lighter, diluted, less concentrated interpretation of a more concentrated product, typically a pure parfum. The cologne version is often the lightest concentration from a line of fragrance products. Finally, the term "cologne" has entered the English language as a generic, overarching term to denote a fragrance typically worn by a man as opposed to a woman, regardless of its concentration. The actual product worn by a man may technically be an eau de toilette, but he may still say that he "wears cologne". A similar problem surrounds the term "perfume", which is sometimes used in a generic sense to refer to fragrances marketed to women, whether or not the fragrance is actually an extrait. Classical colognes first appeared in Europe in the 17th century. The first fragrance labeled a "parfum" extract with a high concentration of aromatic compounds was Guerlain's ''

'' in 1889. Eau de toilette appeared alongside parfum around the turn of the century. The EdP 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. EdP is probably the most widespread strength concentration, often the first concentration offered, and usually referred to generically as "perfume."


Imprecise terminology

The wide range in the percentages of aromatic compounds that may be present in each concentration means that the terminology of extrait, EdP, EdT, and EdC is quite imprecise. Although an EdP will often be more concentrated than an EdT and in turn an EdC, this is not always the case. Different perfumeries or perfume houses assign different amounts of oils to each of their perfumes. 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 amounts vary among perfume houses. An EdT from one house may have a higher concentration of aromatic compounds than an EdP from another. Furthermore, some fragrances with the same ''product name'' but having a different ''concentration'' may not only differ in their dilutions, but actually use different perfume oil mixtures altogether. 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. ''

'' is a good example: its parfum, EdP, EdT, and now-discontinued EdC concentrations are in fact different compositions (the parfum dates to 1921, whereas the EdP was not developed until the 1980s). In some cases, words such as ''extrême'', ''intense'', or ''concentrée'' that might indicate a higher aromatic concentration are actually completely different fragrances, related only because of a similar perfume ''accord''. An example of this is Chanel's ''Pour Monsieur'' and ''Pour Monsieur concentrée''. 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 the modern fragrance world, especially as fragrances are becoming more unisex. Women's fragrances used to be common in all levels of concentration, but today are mainly seen in parfum, EdP and EdT concentrations.


Solvent types

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 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

Applying fragrances

The conventional application of pure perfume (parfum extrait) in Western cultures 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 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.


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. 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.Perfume connoisseurs speak of a fragrance's "sillage", or the discernible trail it leaves in the air when applied. Fortineau, Anne-Dominique (2004). "Chemistry Perfumes Your Daily Life". ''Journal of Chemical Education''.81(1)Edwards, Michael (2006). "Fragrances of the World 2006". ''Crescent House Publishing''. The trail of scent left behind by a person wearing perfume is called its ''sillage'', after the French word for "

", as in the trail left by a boat in water.


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: Also called the ''head 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. Examples of top notes include mint, lavender and coriander. *Middle notes: Also referred to as ''heart notes''. The scent of a perfume that emerges just prior to the dissipation of the top note. 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. Examples of middle notes include seawater, sandalwood and jasmine. *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. Examples of base notes include tobacco, amber and musk. 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 the fragrance components presented as a ''fragrance pyramid'', using imaginative and abstract terms for the components listed.


Olfactive families

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 a single aromatic material. The family classification is a starting point to describe a perfume, but does not fully characterize it.


Traditional categories

The traditional categories which emerged around 1900: * Citrus: The oldest fragrance family that gave birth to lightweight eau de colognes. Development of newer fragrance compounds has allowed for the creation of more tenacious citrus fragrances. Examples: ''4711'', Guerlain's ''Eau de Cologne Impériale'', Penhaligon's ''Quercus''. *Single Floral: Fragrances dominated by the scent of a particular flower, i.e., rose, carnation, iris. In French this type of fragrance is called a ''soliflore''. Example:

Fragrance wheel

This newer classification method is widely used in retail and the fragrance industry, created in 1983 by the perfume consultant Michael Edwards. The new scheme simplifies classification and naming, as well as showing the relationships among the classes. The five main families are ''Floral'', ''Oriental'', ''Woody'', ''Aromatic Fougère'', and ''Fresh'', the first four from the classic terminology and the last from the modern oceanic category. Each of these are divided into subgroups and arranged around 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.

Synthetic sources

Many modern perfumes contain synthesized odorants. Synthetics can provide fragrances which are not found in nature. For instance,
Calone Calone or methylbenzodioxepinone, trade-named Calone 1951, also known in the industry as "watermelon ketone", was discovered by Pfizer in 1966. It is used to give the olfactory impression of a fresh seashore through the marine and ozone nuance ...
, 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. 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: * Givaudan * International Flavors and Fragrances (IFF) * Firmenich * Takasago *

Characteristics

Natural and synthetics are used for their different odor characteristics in perfumery


Obtaining natural odorants

Before perfumes can be composed, the odorants used in various perfume compositions must first be obtained. Synthetic odorants are produced through
organic synthesis Organic synthesis is a special branch of chemical synthesis and is concerned with the intentional construction of organic compounds. Organic molecules are often more complex than inorganic compounds, and their synthesis has developed into one o ...
and purified. Odorants from natural sources require the use of various methods to extract the aromatics from the raw materials. The results of the extraction are either

s, absolutes, concretes, or butters, depending on the amount of waxes in the extracted product.Camps, Arcadi Boix (2000). "Perfumery Techniques in Evolution". ''Allured Pub Corp''. All these techniques will, to a certain extent, distort the odor of the aromatic compounds obtained from the raw materials. This is due to the use of heat, harsh solvents, or through exposure to oxygen in the extraction process which will denature the aromatic compounds, which either change their odor character or renders them odorless. * Maceration/Solvent extraction: The most used and economically important technique for extracting aromatics in the modern perfume industry. Raw materials are submerged in a solvent that can dissolve the desired aromatic compounds. ''Maceration'' lasts anywhere from hours to months. Fragrant compounds for woody and fibrous plant materials are often obtained in this manner as are all aromatics from animal sources. The technique can also be used to extract odorants that are too volatile for ''distillation'' or easily denatured by heat. Commonly used solvents for ''maceration/solvent extraction'' include ethane, hexane, and

Fragrant compounds that are released from the raw material by the high heat often undergo anhydrous pyrolysis, which results in the formation of different fragrant compounds, and thus different fragrant notes. This method is used to obtain fragrant compounds from fossil amber and fragrant woods where an intentional "burned" or "toasted" odor is desired. ** ''Fractionation'': Through the use of a

, different fractions distilled from a material can be selectively excluded to modify the scent of the final product. Although the product is more expensive, this is sometimes performed to remove unpleasant or undesirable scents of a material and affords the perfumer more control over their composition process. * Expression: Raw material is squeezed or compressed and the

s are collected. Of all raw materials, only the fragrant oils from the peels of fruits in the citrus family are extracted in this manner since the oil is present in large enough quantities as to make this extraction method economically feasible. * Enfleurage: Absorption of aroma materials into solid fat or wax and then extraction of odorous oils with ethyl alcohol. Extraction by enfleurage was commonly used when distillation was not possible because some fragrant compounds denature through high heat. This technique is not commonly used in the modern industry due to prohibitive costs and the existence of more efficient and effective extraction methods.


Fragrant extracts

essential oil An essential oil is a concentrated hydrophobic liquid containing volatile (easily evaporated at normal temperatures) chemical compounds from plants. Essential oils are also known as volatile oils, ethereal oils, aetheroleum, or simply as the o ...
s", 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. * Absolute: Fragrant materials that are purified from a ''pommade'' or ''concrete'' by soaking them in ethanol. By using a slightly hydrophilic compound such as ethanol, most of the fragrant compounds from the waxy source materials can be extracted without dissolving any of the fragrantless waxy molecules. Absolutes are usually found in the form of an oily liquid. * Concrete: Fragrant materials that have been extracted from raw materials through ''solvent extraction'' using volatile hydrocarbons. Concretes usually contain a large amount of wax due to the ease in which the solvents dissolve various hydrophobic compounds. As such concretes are usually further purified through distillation or ethanol based solvent extraction. Concretes are typically either waxy or resinous solids or thick oily liquids. *

: Fragrant materials that have been extracted from a source material directly through ''distillation'' or ''expression'' and obtained in the form of an oily liquid. Oils extracted through expression are sometimes called ''expression oils''. *Pomade: A fragrant mass of solid fat created from the '' enfleurage'' process, in which odorous compounds in raw materials are adsorbed into animal fats. Pommades are found in the form of an oily and sticky solid. * Tincture: Fragrant materials produced by directly soaking and infusing raw materials in ethanol. Tinctures are typically thin liquids.

Composing perfumes

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 perfumer

The job of composing perfumes that will be sold is left up to an expert on perfume composition or known in the fragrance industry as the ''perfumer''. They are also sometimes referred to affectionately as a "''Nez''" (French for ''nose'') due to their fine sense of smell and skill in smell composition. 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 the formulation to the customer, often with modifications of the composition of the perfume. The perfume composition will then be either used to enhance another product as a ''functional fragrance'' ( shampoos,

s, car interiors, etc.), or marketed and sold directly to the public as a ''fine fragrance''.


Technique

Although there is no single "correct" technique for the formulation of a perfume, there are general guidelines as to how 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
antioxidant Antioxidants are compounds that inhibit oxidation, a chemical reaction that can produce free radicals. This can lead to polymerization and other chain reactions. They are frequently added to industrial products, such as fuels and lubricant ...
s to improve the marketability and shelf life of the perfume, respectively.


Basic framework

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: *''Primary scents'' (Heart): Can consist of one or a few main ingredients for a certain concept, such as "rose". Alternatively, multiple ingredients can be used together to create an "abstract" primary scent that does not bear a resemblance to a natural ingredient. For instance, jasmine and rose scents are commonly blends for abstract floral fragrances. Cola flavourant is a good example of an abstract primary scent. *''Modifiers'': These ingredients alter the primary scent to give the perfume a certain desired character: for instance, fruit esters may be included in a floral primary to create a fruity floral;
calone Calone or methylbenzodioxepinone, trade-named Calone 1951, also known in the industry as "watermelon ketone", was discovered by Pfizer in 1966. It is used to give the olfactory impression of a fresh seashore through the marine and ozone nuance ...
and citrus scents can be added to create a "fresher" floral. The cherry scent in cherry cola can be considered a modifier. *''Blenders'': A large group of ingredients that smooth out the transitions of a perfume between different "layers" or bases. These themselves can be used as a major component of the primary scent. Common blending ingredients include linalool and hydroxycitronellal. *''Fixatives'': Used to support the primary scent by bolstering it. Many resins, wood scents, and amber bases are used as fixatives. The top, middle, and base notes of a fragrance may have separate primary scents and supporting ingredients. The perfume's

s are then blended with ethyl alcohol and water, aged in tanks for several weeks and filtered through processing equipment to, respectively, allow the perfume ingredients in the mixture to stabilize and to remove any sediment and particles before the solution can be filled into the perfume bottles.


Fragrance bases

Instead of building a perfume from "ground up", many modern perfumes and colognes are made using ''fragrance bases'' or simply bases. Each base is essentially modular perfume that is blended from essential oils and aromatic chemicals, and formulated with a simple concept such as "fresh cut grass" or "juicy sour apple". Many of Guerlain's ''Aqua Allegoria'' line, with their simple fragrance concepts, are good examples of what perfume fragrance bases are like. The effort used in developing bases by fragrance companies or individual perfumers may equal that of a marketed perfume, since they are useful in that they are reusable. On top of its reusability, the benefit in using bases for construction are quite numerous: #Ingredients with "difficult" or "overpowering" scents that are tailored into a blended base may be more easily incorporated into a work of perfume #A base may be better scent approximations of a certain thing than the extract of the thing itself. For example, a base made to embody the scent for "fresh dewy rose" might be a better approximation for the scent concept of a rose after rain than plain rose oil. Flowers whose scents cannot be extracted, such as

. #A perfumer can quickly rough out a concept from a brief by combining multiple bases, then present it for feedback. Smoothing out the "edges" of the perfume can be done after a positive response.


Reverse engineering

Creating perfumes through reverse engineering with analytical techniques such as Gas chromatography–mass spectrometry (GC/MS) can reveal the "general" formula for any particular perfume. The difficulty of GC/MS analysis arises due to the complexity of a perfume's ingredients. This is particularly due to the presence of natural essential oils and other ingredients consisting of complex chemical mixtures. However, "anyone armed with good GC/MS equipment and experienced in using this equipment can today, within days, find out a great deal about the formulation of any perfume... customers and competitors can analyze most perfumes more or less precisely." Antique or badly preserved perfumes undergoing this analysis can also be difficult due to the numerous degradation by-products and impurities that may have resulted from breakdown of the odorous compounds. Ingredients and compounds can usually be ruled out or identified using gas chromatograph (GC) smellers, which allow individual chemical components to be identified both through their physical properties and their scent. Reverse engineering of best-selling perfumes in the market is a very common practice in the fragrance industry due to the relative simplicity of operating GC equipment, the pressure to produce marketable fragrances, and the highly lucrative nature of the perfume market.


Copyright

It is doubtful whether perfumes qualify as appropriate copyright subject matter under the US Copyright Act. The issue has not yet been addressed by any US court. A perfume's scent is not eligible for trademark protection: the scent serves as the functional purpose of the product. In 2006 the Dutch Supreme Court granted copyright protection to Lancôme's perfume ''Tresor'' (''Lancôme v. Kecofa''). The

has twice taken the position that perfumes lack the creativity to constitute copyrightable expressions (''Bsiri-Barbir v. Haarman & Reimer'', 2006; ''Beaute Prestige International v. Senteur Mazal'', 2008). Sometimes, a knock-off perfume would use an altered name of the original perfume (for instance, now-discontinued ''Freya'' by Oriflame perfume has a similar-designed copy produced as "''Freyya''"). It is still questionable if perfume's "functional purpose" can be protected with technical patent (one which lasts 15 years). Apparently, Russian "Novaya Zarya" labels their colognes as "hygienic lotions" for a similar reason. A counterexample: NovZar's more-than-century-old ''Shipr'' chypre and Troinoi cologne are being produced by other companies in Russia in similar bottles.


Numbered perfumery, "analogs"

A different kind of copying perfumes is known in ex-USSR countries as "''номерная парфюмерия''" (literally "numbered perfumery"): A "number-making" company with perfumery equipment would use their own, one-style-for-all cheap bottle; ''de jure'' labeling a knock-off perfume as an "aroma in the direction of he well-known perfume or a "version" of certain branded perfume. This way, the production costs of initially cheap scents are reduced, since the bottle is used neither for plain counterfeiting nor for subtle re-designing. The questionable part of numbered perfumery naming is the idea to openly mark perfume #XXX (say, #105) as either "type" or "version", or "''аромат направления''" (literally "aroma in the direction of") of a well-known perfum. * Resellers in offline stores (in malls, airport shops) can offer "fillable" perfumery, sometimes using weasel wording to justify the price. * Such perfumes usually get three-digit numbers as an officially registered name, which is stickered to the bottles. * When it comes to propellant, a "number" usually has an alcohol base lmostwithout stabilization (which may give strong "alcohol base stench", altering perfume's scent into the "smell of cheapness" phenomenon). ** To avoid this, many "numbers" can be made with (di)propylenglicol base and come as "perfume oil(s)". PG or DPG based numbered perfumery comes in 50ml plastic bottles and is purposed for tiny rollers; (D)PG is not usable in spray bottles (while not affected by the "smell of cheapness" issue nonetheless). Some companies offer all of their own "numbers" in both alcohol based and (D)PG based variants. In small online "bulk", however (in purchases over 5000RUB), a whole 100ml bottle of such perfume (or 50ml bottle of "scent oil" of same "direction") costs only around 6 EUR.


Health and environmental issues

Perfume ingredients, regardless of natural or synthetic origins, may all cause health or environmental problems when used. Although the areas are under active research, much remains to be learned about the effects of fragrance on human health and the environment.


Immunological; asthma and allergy

Evidence in peer-reviewed journals shows that some fragrances can cause asthmatic reactions in some individuals, especially those with severe or atopic asthma. Many fragrance ingredients can also cause headaches, allergic skin reactions or nausea. In some cases, an excessive use of perfumes may cause allergic reactions of the skin. For instance, acetophenone, ethyl acetate and acetone while present in many perfumes, are also known or potential respiratory allergens. Nevertheless, this may be misleading, since the harm presented by many of these chemicals (either natural or synthetic) is dependent on environmental conditions and their concentrations in a perfume. For instance, linalool, which is listed as an irritant, causes skin irritation when it degrades to peroxides, however the use of antioxidants in perfumes or reduction in concentrations can prevent this. As well, the furanocoumarin present in natural extracts of grapefruit or celery can cause severe allergic reactions and increase sensitivity to ultraviolet radiation. Some research on natural aromatics have shown that many contain compounds that cause skin irritation.Environmental and Health Assessment of Substances in Household Detergents and Cosmetic Detergent Product

However some studies, such as IFRA's research claim that Perfumery's opopanax, opoponax is too dangerous to be used in perfumery, still lack scientific consensus. It is also true that sometimes inhalation alone can cause skin irritation. A number of national and international surveys have identified balsam of Peru, often used in perfumes, as being in the "top five" allergens most commonly causing patch test reactions in people referred to dermatology clinics. A study in 2001 found that 3.8% of the general population patch tested was allergic to it. Many perfumes contain components identical to balsam of Peru. Balsam of Peru is used as a marker for perfume allergy. Its presence in a cosmetic is denoted by the INCI term ''Myroxylon pereirae''. Balsam of Peru has been banned by the

since 1982 from use as a fragrance compound, but may be present as an extract or distillate in other products, where mandatory labelling is not required for usage of 0.4% or less.


Carcinogenicity

There is scientific evidence that nitro-musks such as musk xylene could cause cancer in some specific animal tests. These reports were evaluated by the EU Scientific Committee for Consumer Safety (SCCS, formerly the SCCNFP) and musk xylene was found to be safe for continued use in cosmetic products. It is in fact part of the procedures of the Cosmetic Regulation in Europe that materials classified as carcinogens require such a safety evaluation by the authorities to be allowed in cosmetic consumer products. Although other ingredients such as polycyclic

s, have been reported to be positive in some in-vitro hormone assays, these reports have been reviewed by various authorities. For example, for one of the main polycyclic musks Galaxolide (HHCB) these reviews include those of the EU Scientific Committee on Consumer Safety, the EU's Priority Substances Review, the EU Scientific Committee on Health and Environmental Risk, and more recently also the US EPA. The outcome of all of these reviews over the past decade or so is that there are no safety concerns for human health. Reviews with similar positive outcomes also exist for another main polycyclic musk (AHTN)—for instance, on its safe use in cosmetics by the EU. Many natural aromatics, such as oakmoss absolutes, basil oil, rose oil and many others contain allergens or carcinogenic compounds, the safety of which is either governed by regulations (e.g. allowed methyl eugenol levels in the EU Cosmetics Regulation (Entry102, AnnexIII of the EU Cosmetics Regulation.) or through various limitations set by the International Fragrance Association.


Environmental


Pollution

Synthetic musks are pleasant in smell and relatively inexpensive, as such they are often employed in large quantities to cover the unpleasant scent of laundry detergents and many personal cleaning products. Due to their large-scale use, several types of synthetic musks have been found in human fat and milk, as well as in the sediments and waters of the Great Lakes. These pollutants may pose additional health and environmental problems when they enter human and animal diets.


Species endangerment

The demands for aromatic materials such as sandalwood, agarwood, and musk have led to the endangerment of these species, as well as illegal trafficking and harvesting.


Safety regulations

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 allergens 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 traditionally make use of oakmoss extract, being reformulated.


Preserving perfume

Fragrance compounds in perfumes will degrade or break down if improperly stored in the presence of heat, light, oxygen, and extraneous organic materials. Proper preservation of perfumes involves keeping them away from sources of heat and storing them where they will not be exposed to light. An opened bottle will keep its aroma intact for several years, as long as it is well stored. However, the presence of oxygen in the head space of the bottle and environmental factors will in the long run alter the smell of the fragrance. Perfumes are best preserved when kept in light-tight aluminium bottles or in their original packaging when not in use, and refrigerated to relatively low temperatures: between 3–7 °C (37–45 °F). Although it is difficult to completely remove oxygen from the headspace of a stored flask of fragrance, opting for spray dispensers instead of rollers and "open" bottles will minimize oxygen exposure. Sprays also have the advantage of isolating fragrance inside a bottle and preventing it from mixing with dust, skin, and detritus, which would degrade and alter the quality of a perfume. There exist several archives and museums devoted to the preservation of historical perfumes, namely the
