Room fragrancing with tradition

Fragrances awaken memories in us. We also call this sensation olfactory perception. Some fragrances immediately take us back to our childhood. Images are created in front of our inner eye which are triggered by the respective scent. We are accompanied by scents that we associate with a beautiful event for the rest of our lives. And always, when we perceive this smell, we are reminded of this beautiful event. These memories are activated by the limbic system, the location of our emotions. The subjective sense of smell is influenced by experience and therefore individually different.
The physical- and psycho-objective effect is the same for every human irrespective of the experience values, since neurochemical substances such as encephalins, endorphins, serotonin and noradrenalin are released in the limbic system by olfactory stimuli. This knowledge serves, among other things, as the basis of aromatherapy, in which the effect of natural aromas and essences is specifically applied. Special use is made of room scenting in sauna, spa and wellness because here the effect of the scents used on the body is sought directly.

However, the scenting of rooms is not new, but has a long tradition.
Legend has it that King Solomon scented the guest rooms for the Queen of Saba so beguilingly that the Ethiopian imperial dynasty arose from the royal relationship.
Room fragrance is an ancient cultural asset. People have always used plant scents, i.e. natural essential oils, for their well-being. But also to stay healthy or to become healthy again. This huge wealth of experience is increasingly confirmed by the scientific findings of recent years. The renaissance of room scenting and the growing importance of aromatherapy are therefore only logical. The scenting of rooms is originally also an expression of appreciation towards the guest or the customer. A successful room fragrancing is also today not conceivable without this basis.

Possibilities of room fragrancing

While dealing with room fragrancing in the sauna, spa and wellness area, the first question arises: How do you bring the fragrance into a room or to an application?

There are three ways to transport fragrance:
• Via water
• Via steam
• Via air

Where and how are these three fragrance transport routes used?

Fragrance via water
• In the shower / adventure shower
• In the brine inhalation with scent
• In the sauna about the sauna infusion. Sauna versions: Finnish sauna, Russian banya.
• In relaxation rooms through a fragrance fountain, which also serves as a humidifier, e.g. in the tepidarium and laconium.
• Typical applications of indoor climate: hot and dry (sauna), warm or cold (adventure shower), cold (brine inhalation), warm and dry (laconium, tepidarium)

Fragrance via steam
• In the steam bath and caldarium
• In the Hamam, Rhassoul
• In the biosauna and soft sauna
• For air humidification
• Typical application area of room climate: hot and humid (steam bath) as well as warm and humid (Hamam, Rhassoul)

Fragrance via air
• In the relaxation room
• In the relax room
• In the Laconium
• In the Tepidarium
• In changing rooms
• In the entrance area and lobby
• Typical climate conditions: warm and dry (laconium, tepidarium, resting room, etc.),
• Normal room climate approx. 25°C (lobby, changing room)

Kemitron manufactures fragrance dosing pumps for all the above-mentioned areas. These pumps are characterised by the possibility of spreading a constant fragrance over a longer or fixed period of time, fully automatically, even in larger rooms, without anyone constantly having to actively watch for it. Fragrance, intensity and interval are individually adjustable.
The dosing pumps and dosing systems are high-quality and durable. Many years of experience in production, operation, installation and maintenance enable us to competently advise you on the correct installation as well as on the selection of fragrances for the corresponding application area.

Clear, active, and fresh Kemitron – world of fragrances about the mint

World of fragrances about the mint – Mythical stories and harmonious fragrances are often connected in the world of legends, as also shown here:
Hades, the ruler of the underworld fell in love with the young and pretty nymph Menthae. When Persephone, his wife, found out about it, she became jealous, and transformed the nymph into a plant, which is living on soil as creeper and was supposed to be stepped on by feet. Hades was not able to undo the transformation but he lessened the effect on Menthaes fate by giving her an enchanting fragrance which she exuded when she was touched.

The Indus delta – the birthplace of the mint
In fact, the mint was not only known to the ancient Greeks. Just as many spice, sacrifice, and medicinal plants it originates from the Indian subcontinent and spread from there into the ancient world. The Indus delta is its birthplace and also the name was probably borrowed from the ancient Indian “Manthe” which means rubbing. The Egypts knew and used it as medicinal and ritual herbage as well as burial gift. The ancient Greeks also knew how to make use of it: Mint bouquets at table were thought to stimulate the appetite, mint wreaths on the hair were supposed to prevent a hangover at drinking sessions or act as aphrodisiac.
The success story of the mint continued via the Romans and the Celts until medieval times, when Hildegard of Bingen also planted mint in her herb garden. Charlemagne had the plant grown by regulation for medicinal purposes and in England during the 17th century, mint leaves where used to keep the drinking water on ships clean.
Until today, our most numerous mint species is the peppermint. It's calming, refreshing, and antispasmodic on the respiratory organs and is used on muscular problems in everyday life or sports.

The fragrant message of the mint
Also in form of mint oil the power of the mint has been used for centuries. Clear, fresh, and active – that is its fragrant message. Mint oil is pervasive, peppery hot, and spicy, leaving a cooling effect on the skin if used in infusion minty fragrances, which is particularly noticeable with a following cold application. It is characteristic for sporty perfumes, masculine cosmetics as well as fresh and cool room and wellness fragrances.
The wide range of mint plants encouraged the experts from Wendlingen, to create an as large spectrum in their world of fragrances. They range from peppermint to the Japanese mint. For its fragrance creations, Kemitron uses a high concentration of natural essential oils. Because only they achieve the wide variety in modes of action on both body and senses. They are only supplemented with nature-identical
oils, if natural raw materials are banned or difficult to acquire for reasons of natural conservation or the protection of endangered species, or are too expensive as natural oils that the end product cannot be marketed at a reasonable price.


Usage of Kemitron fragrances in certified facilities

There are many different certifications for spa, sauna and wellness facilities. Since the certification requirements can vary immensely and there is no uniform regulation, we would like to inform you about the usage of our fragrances in these facilities.
In principle there are no specifications, which connect selected products to assigned facilities! Like in other areas, the quality of the products is of crucial relevance for systems to run easy and on low maintenance.
In this context, a lot of individual components go hand in hand: for example fragrances based on emulsifiers can leave residues and congest pipes and valves. Therefore we do not use emulsifiers as fragrance carriers at all instead we use alcohol, which volatizes residue-free and allows the fragrances to unfold in a dependable and consistent quality.(1)

The name Kemitron stands for highest quality
First-class fragrances need time to develop. To let the aroma unfold in the best way possible and therefore to ensure an unique experience for your customers, quality is of vital importance. Kemitron is well aware of its responsibilities and puts major attention to keep the entire value-creation chain from the finest selection of the odoriferous substance, to the development, through to production in our own hands. Our corporate philosophy obliges us to sustainably protect nature and the environment by handling resources carefully – namely in a holistic way, with the purchase of raw materials as well as the use of our products. We know that only high-quality oils create a long-lasting fragrance experience and therefore ensure a healthy relaxation. This is why at Kemitron we use a high concentration of natural essential oils. Because only they achieve the wide variety in modes of action on both body and senses. They are only supplemented with nature-identical oils, if natural raw materials are banned or difficult to acquire for reasons of natural conservation or the protection of endangered species, or are too ex- pensive as natural oils that the end product cannot be marketed at a reasonable price.
Sustainability on principle
All odoriferous substances and fragrances we purchase and use in manufacturing our products, are subject to the IFRA standard codex (2), which is based on scientific analyses of the RIFM (3). This sophisticated composition is one fundamental reason for the fact, that Kemitron fragrances remain stable in their intensity, even if the container has been in use for a while. We see this also as an essential contribution to a considerate handling of nature. Furthermore our Aromee products are remarkable for their high yield, efficiency and therefore for their cost-effectiveness. We have taken a conscious decision not to use water-based emulsions as well as emulsified fragrance compounds and the associated addition of preservatives. On this account we have not been informed of any health-impairing effects or other reactions resulting from Kemitron Aromee products. A confirmation will only be valid to the extent, that it can be verified that original Kemitron products were used and the dosage recommendations complied with.

Menthol – the cold fragrance-magic

In the past, menthol was used in mixtures with camphor, peppermint, eucalyptus and sage in cold-drops or creams against rhinitis.
In the meantime, it has been incorporated in other areas of application. In sauna and wellness-facilities infusions with menthol addition are now very widespread and have become vital. The cool and icy menthol effect is a fixed component of polar ice infusions, in heroic Terminator infusions it even is the center of the show, rotgut infusions use the cold-unfavorable properties.
The cooling effect in the usage of menthol occurs through the contact with the cold receptors on the skin. Due to the quick evaporation via the receptors a cold stimulus is activated, which causes a seemingly cooling effect. The skin temperature stays constant and the cooling effect is therefore only simulated.
Menthol is a white to colorless, needle-shaped crystal that is mainly pulled out of the essential oils of plants of the menthe family and other labiates.
The winning of the crystalline menthol is performed by freezing out the ultrapure peppermint oil by minus 40 °C. The most plain peppermint odor contains the left-turning menthol, which is extracted from the Mentha piperita plant.
Mostly the japanese peppermint and the chinese Mentha arvansis, which both contain more than 70% menthol, are used for the manufacturing of mint oil. Important cultivation areas exist besides the heartlands also in USA, Brasilia and India. Many other plants, mainly labiates, i.e. rosemary, thyme and sage as well as some nettle species also contain little amounts of menthol. It is soluble in alcohol or essential oils, but not in water. 
Every year about 20.000 tons of menthol are manufactured, whereby around 70% come from natural plant-based mint oil with the rest being produced synthetically.
Menthol is versatile:

  • As disinfecting addititve in spray agents, i.e. against mites in beehives
  • In food products: Candies and liquors (main application field)
  • Fragrance area: perfumes and scented fragrances
  • In spa and wellness: Experience showers, sauna infusions, ice fountains
  • Cosmetics and hygiene: Toiletry, hair tonic, bath products, dental and oral care products
  • Medicine: Ointments and rubs against skin irritations due to insect bites, minor burns and anti itching. In ointments menthol can also have an antispasmodic effect, i.e. for gastrointestinal discomforts.

However, it should always been paid attention: Careful with overdosage! As with many other things, menthol is harmful in too great quantities. Therefore, always read the instructions on the package. And don’t remove the crystals with bare hands.


Fragrance solution or fragrance emulsion in sauna and steam bath?

Fragrances are deployed in saunas or spas to surround visitors, because fragrances influence our mood and health.

However, if fragrances for sauna, wellness, and spa areas need to be purchased, the range is huge. One of the decisions that have to be made is whether alcohol or emulsion-based fragrances should be used. These differ on a number of points, which we would like to explain:

In a fragrance solution or fragrance concentrate, the essential oils are dissolved in alcohol. Due to their composition and the substantially continuous evaporation process, alcohol-based fragrance solutions can be used very economical and efficient. They are fully absorbed and quick by the steam. Contact times are low. Residues only occur, if the steam-contact-time is chosen too short or if the dosage is not matched to the steam flow.
Excess-amounts of the solutions are also absorbed quickly. The specific aroma of the essential oil reaches the steam bath cabin unadulterated. The fragrance concentrate and the fragrance solution evaporate in the sauna on the stone without leaving any residues the aroma remains stable and can spread throughout the cabin with the steam.

On the other hand, the shares of the essential oils in fragrance emulsions (fragrance milk) are dissolved with the help of an emulsifier and water. Because emulsions are mostly manufactured in a combined system, a high share of emulsifier is necessary.
The evaporation process for fragrance emulsions is significantly more unpleasant since the water share only evaporates incomplete, the emulsifier (up to 20 % of the emulsion) not at all. The not evaporated share of the fragrance emulsion remains standing in the pipe and impairs the steam flow or runs as greasy distillate out of the valve into the cabin. Since a greater part of the essential oil is attached to the emulsifier or to the emulsifier-water-mixture, this share of it drains off unused together with the distillate. In saunas an emulsifier-layer remains on the stones.

To receive the same fragrance intensity, the consumption of the application quantity can be increased by a multiple compared to the solutions. The usage may be further reduced if the dosage arrangements are not favorable, i.e. if the steam contact times are too short. Alcohol-based fragrance solution enables a quality monitoring using simple methods, in comparison to emulsions, where monitoring is practically impossible. Therefore in emulsions can be incorporated shares of inferior quality essential oils (so-called “terpenes”) as well as inadmissible emulsifiers (i.e. technical emulsifiers). If used, this can lead to skin irritations and reddening of the mucous membrane subsides.

Not homogenized emulsions tend to unmix fast, which means that the oil and the aqueous phase separate, the oil floats on top of the emulsion. If they are unmixed they won’t get completely consistent again, not even by subsequent mixing (intensive shaking). Due to phase-separation significant quality differences in the fragrance supply of the cabin occur, since the watery phase doesn’t contain any essential oil, the layer floating on the surface however, consists of essential oil shares. Additionally, the different composition of the phases leads to adhesion of the steam pump and the steam valve.

Also the inherent odor of the emulsifier can superimpose the specific aroma of the essential oil. Furthermore, the emulsifiers and water-based solutions often distort the typical nature of plants and reduce their characteristics. Immediately with opening of the fragrance emulsion containers, contamination starts, which is accelerated by storage in warm rooms. This can be delayed by adding preservatives. Therefore Emulsions are durable for six weeks.

Alcohol-based fragrance solutions and fragrance concentrates don’t have this contamination problem. They stay stable in their mixture and the same in their odor intensity, even if a container is in use over a longer period.

The use of fragrances in saunas, steam baths, hot air- and aroma cabins support the characteristics of the application. Therefore, attention to the fragrance solutions for containing mostly natural essential oils should be paid. Alcoholic solutions intensify the characteristic radiance of the essential oils and support their properties while the nature of the plants is preserved.

This means summarized: for a very good reason Kemitron only uses alcohol instead of emulsifiers (emulsion or emulsion-milk) as fragrance-carrier for its Aromee products: with a very good fragrance development, alcohol supports the quality and leaves no residues on the sauna stone or the pipes of the steam bath.


Fragrance is life

A journey through the conceptions of the ancients on gods, incense, aromatic plants, and fragrances


The importance of fragrances in the ancient world

From the earliest human history until the early classical period, fragrances were exclusively reserved for the use of rulers and the priestly class. Only these groups were believed to have the knowledge and capabilities to use fragrances and incense to set up contact to the world of gods. The healing effect of aromatic plants, woods, and the fragrances themselves were discovered early, and knowledge of these powers systematically collected by emperors and other rulers. They enjoyed the unlimited respect of a god-fearing population, for – in established imagination – only those with almost divine powers could have the knowledge of healing. More than 3,500 years ago, the ancient Egyptians had the following proverb, known throughout the land:

“A day without fragrance is a wasted day.“

Original saying adapted

Egypt – The cradle of fragrance culture

To this very day, Egypt is known as a country of fragrance culture. It was there that the importance of fragrances and aromatic compounds for everydays life was first recognized.

Thus the female pharaoh Hatshepsut, who reigned in Egypt from approximately 1470 to 1445 B. C., issued a divine decree that, from then on, incense, fragrances, and cosmetics were no longer to be permitted to the priestly class and the ruling family alone, but could also be used by all Egyptians, regardless of the social class.


Fragrance is life

In many ancient cultures it was the widespread opinion that the gods only subsisted on the winds and fragrances sacrificed by humans: the “per fumum”.

Also dance, song, and music were believed to represent food for the gods, in some parts of the ancient world. Therefore burnt offerings, fumigation, and fragrance sacrifices were a way to talk to the unearthly, the heavenly – the gods – to be mild and merciful. Furthermore, they served as some sort of food for the gods. For it was believed that the gods were close, and divine protection assured, if people surrounded theirselves with the fragrances of smoke and incense.

Tradition of ayurvedic medicine and perfume manufacturing

The origins of ayurvedic health concept date at least 5,000 years back to the foothills of the Himalayas in the northwest of the Indian subcontinent.

Characterized by “veda” (knowledge), it already knew the positive effect of plant aromas as well as herbs, spices, resins, and minerals. Fragrances, that are distilled essences of plants and flowers, were appreciated not only for their medicinal properties, but also as natural perfumes. The tradition of manufacturing perfume (the distilling of fragrances) can be traced back to earlier than 3,000 B.C. Distilling equipment made of terracotta from this period has been found in western India and Pakistan. Leather bottles were also used for distilling.

The importance of fragrances in other advanced civilizations

In other advanced civilizations at times of the Sumerians, Babylonians, and Assyrians, as well as in the early Indus civilization (around 2,800 B.C.) and the high period of the Harappan culture fragrances, aromatic plants, plant extracts, and cosmetics were used only by the priestly caste during religious ceremonies and funeral rites to communicate directly with the gods.


European fragrance culture

Offering, object of exchange, protection against diseases or seduction – the history of fragrances and perfumes reflect economy, medicine, faith and customs of different eras.

  • By the end of the 19th century under the influence of the upper bourgeoisie, the modern perfume industry develops. At the 1868 World Exhibition, the first purely synthetic perfume is presented.
  • In the Age of Enlightment, hygiene is recalled, finer fragrances are preferred, great importance is attached to make-up and hairstyles, and people submit to the dictatorship of fashion. Eau de Cologne is invented by Jean-Antoine Farina.
  • Perfuming over washing – based on the model of Versailles, men and women of the classical era mask their body odors with perfume. It is the age of perfume and powder manufacturers. Grasse und Montpellier compete to get medical herbs and aromatic plants.
  • The great discoverers of the Renaissance introduce new raw materials from America and India. Alchemical recipes are replaced by first chemical treatises. At the royal courts, a competition about the secrets of beauty starts.
  • In the Middle Ages, crusaders bring raw materials and perfume techniques from the oriental region to Europe. It was believed, that good odours keep out epidemics and enhance physical well-being.
  • In ancient Egypt and ancient Greece, salvationand scented plants, woods and resins were given to the gods as a sign of devotion. Incenses, oils and balms were used by rich and poor people to get close to devine.

Aromatic plants for healing

The use of wild herbs and aromatic plants for ritual purposes and for treating illnesses, extends even further back in human history.

According to legend, the Khoisan people, an ancient tribe in southwestern Africa, knew the use of wild herbs more than 100,000 years ago. They had already established familial structures and developed communities with their own language and close social ties. According to an evaluation of more than 2 million DNA data, conducted under the aegis of Prof. Stephan Schuster of Pennsylvania State University, the Khoisan were among the first modern human beings on the planet. Today, every person alive is directly descended from these ancestors.

Aromatic traditions and rituals

Incense plants, resins, and blossoms were widespread in the ancient world; apart from a few, mostly local exceptions, the same sources of fragrances were used everywhere.

Among the most popular and widely used sources were quince seeds, jasmine flowers, gum mastic, myrrh leaves, rosemary, lavender, juniper berries, cedar wood, oud or agarwood, lotus, and rose petals. The enthusiasm of the ancient Egyptians for flowers and fragrances cannot be explained simply by a fondness for pretty blossoms and pleasant fragrances, but has a deeply rooted religious basis. Thus it is that the word “bouquet” in the ancient Egyptian language uses the same hieroglyph and has the same meaning as the word “life”. It is this tradition that gave rise to a flower ritual performed at funerary ceremonies.

Bundles of aromatic flowers and bottles of fragrance were placed in the coffins that even the gods in the afterlife would still be able to smell the favorite fragrances of the dead. The basis for this tradition is the custom of cultivating flower gardens, widespread in Egypt and originally adopted from the Babylonians. This was done everywhere, even in the cities, to offer a pleasant environment for conversations with the departed, who were allowed to leave the underworld and visit the world of the living in the form of birds.


Perfect sense: With top, middle and base

Well-balanced fragrance compositions

A fragrance is recognized as a harmonious ensemble if three different scent profiles – the top-, middleand base note – blend perfectly with each other. These can vary widely, not only in the length of the effect but each of them also plays a distinct role in the complete concept of the fragrance composition.

Top note
The first thing perceived when a fragrance is tested is the top note. Its role is, to attract interest in total for the fragrance. Naturally, the top note is defined by refreshing, lively and high volatile aromatic substances. Examples for top note essential oils are citrus notes, mint, eucalyptus and basil. Their intensity already evaporates after 10 min, since at that time the middle note of the perfume develops.

Middle note
The middle notes are semivolatile, and secure a smooth and sensitive transition from the first to the third phase. Within the fragrance progress they guide to the flowery, fruitysweet notes and are mainly characterized by floral, spicy and also woody elements. Examples of essential oils for middle notes are: Attar of roses, jasmine, lavender, chamomile, balm, resinous notes, ylang-ylang. This phase shapes the character of the fragrance; therefore the second phase is also referred to as core element.

Base note
The slow volatilizing base notes are the last part of a fragrance procedure of a fragrance composition and still perceptible after hours. Hence they are responsible for the lasting impression in the room, and – depending on the fragrance – very individual. Examples for essential oils for base notes are: Woody notes, resinous notes, vanilla, honey essence, cocoa, patchouli, thyme.


Place unique fragrance notes

We are always surprised and touched by fragrances, if they are – like a perfume – composed of a top-, middle- and a base note. Not for nothing the fragrance compositions of Kemitron comprise of several odoriferous substances. Thus fragrances are not only perceived but consciously experienced because they can be sensed very long. Our basic assortment consists of roundabout sixty permanent available fragrance creations with both, fruity and tender flowery scented notes as well as rejuvenating herb- and bitter woody notes. We complement this assortment with seasonally available fragrances.

This gives you a comprehensive selection, to offer your guests – depending on daytime, target group and occasion – unique fragrance experiences.

We attach great importance to advise you competent during the selection process on the characteristics, behavior patterns and tolerability’s of the right fragrance creation. For example, we recommend in saunas to use only flowery scents, whose character is not significantly changed by heat. Or we advise peppermint to increase the icy feeling in cold water mist.


Conserving resources & special attention on fragrance development

The name Kemitron represents the highest level of quality

Due to the causal network, the quality of the odoriferous substances is of vital importance. Kemitron is well aware of its responsibilities and puts major attention to keep the entire value-creation chain from the finest selection of the odoriferous substance, to the development, through to production in our own hands. Our corporate philosophy obliges us to sustainably protect nature and the environment by handling resources carefully – namely in a holistic way, with the purchase of raw materials as well as the use of our products.

We know that only high-quality oils create a long-lasting fragrance experience and therefore ensure a healthy relaxation. This is why at Kemitron we use a high concentration of natural essential oils. Because only they achieve the wide variety in modes of action on both body and senses. They are only supplemented with nature-identical oils, if natural raw materials are banned or difficult to acquire for reasons of natural conservation or the protection of endangered species, or are too expensive as natural oils that the end product cannot be marketed at a reasonable price.

Fragrances are effective

Many fragrances have a very intensive effect on the human psyche. For example bergamot cheers up and encourages people, jasmine calms them down.

This is primarily due to the fact, that aroma sensations are closely linked to our feelings. Receptors that analyze the fragrance components and forward them via electrochemical impulse directly to the brain are located in the nose.

The signals of the olfactory nerve reach the brain center and affect the vegetative nervous system that controls heartbeat, respiration, body temperature, digestion, sleep rhythm and hormone release. They also affect directly the actual emotional center – the limbic system – which processes emotions and direct instincts. As a part of the limbic system, the hippocampus is responsible for establishment and structuring of long-term memory. This explains also, why fragrances cause spontaneous images and memories in our subconscious mind.
