De las hojas a los laboratorios: una breve historia de la nicotina y su producción


green tobacco leaves, dried tobacco leaves, a male scientist, and a text: From leaves to labs - a brief story of nicotine production

Nicotine is an omnipresent substance. Millions of people consume it on a daily basis, on every continent. Some do it for pleasure, some for medical reasons, and others on social occasions. Not everybody knows, however, that pure nicotine – the raw material used by manufacturers – is a highly dangerous substance, which may bring fatal consequences if handled improperly. From this article, you will learn what are nicotine’s origins, what danger may result from contact with it, and how it is obtained. Below you will find the agenda, that will help you find the information you may be looking for.

Nicotine production process – table of contents:

I. What is pure nicotine?

Pure nicotine is a substance, that occurs, in the greatest amount, and is made out of tobacco plant. Its highest concentration is found in the leaves. The most popular species to produce cigarettes or source nicotine is grown in the world Nicotiana tabacum, however, other species, native to South America, are cultivated as well, for example, Nicotiana rustica, Nicotiana alata, or Lobelia Inflata.

Although Nicotiana rustica leaves contain up to 3 times more nicotine than Nicotiana tabacum, it places second, when it comes to popularity. The reason behind it is Nicotiana tabacum’s smoother taste.

What is worth mentioning, most people have contact with nicotine on a daily basis. Trace amounts of the substance are present in tomatoes, eggplants, or peppers. However, in Chemnovatic offer exemplary products directly related to pure nicotine are: PureNic 99+ or NicSalts.

Is nicotine made naturally?

What is worth mentioning, nicotine is made naturally and made out of tobacco plants. However, synthetic nicotine is also on the market and it is tobacco-free, made in laboratories. It became popular, due to the fact it’s tobacco-free. Consequently, it wasn’t subject to various tobacco-product regulations. You can read more about synthetic nicotine here.

The history of nicotine’s name and how did it arrive in Europe?

Nicotiana tabacum, nicotine’s main source, comes from South America, where indigenous people rolled its leaves, burnt, and inhaled the fumes. The original use of tobacco was for religious and medical purposes. However, the name – nicotine – comes from Jean Nicot de Villemain, a French diplomat and a scholar. He brought the plant to France in 1560. Back in that time, it was believed, that smoking tobacco prevents illnesses and the plague. However, for nicotine to be discovered as an individual substance, mankind had to wait another 300 years. Responsible for this were two German chemists – Wilhelm Heinrich Posselt and Karol Ludwig Reimann – who isolated the substance from Nicotiana tabacum leaves. Moreover, by the end of the XIX century nicotine’s empirical formula was described (1843, Louis-Henri-Frederic Melsens), the structure was discovered (1893, Adolf Pinner) and in 1904 pure nicotine was first synthesized by a Swiss – Ame Pictet.

Although in the past many believed, that tobacco prevents illnesses and cures various conditions, chemists who extracted pure nicotine found it as poison. From today’s perspective, it’s hard to deny the Germans’ statement or at least the danger the substance carries. More, however, on nicotine toxicity later in this article.

Characteristics and features

Now, let’s look at characteristics of pure nicotine. It is an oily liquid with transparent-to-yellow-to-brown colour and hygroscopic properties. Depending on the solvent used to acquire nicotine and the time of exposure to oxygen, temperature, and light the colour may differ. As for solvents, there are various, that may come to use when acquiring nicotine: water below 60 oC, chloroform, petroleum ether, isooctane, or benzene.

II. First steps of the nicotine production

Sourcing tobacco

Before pure nicotine is extracted, one has to grow the tobacco, which blooms from late June to September in the northern hemisphere and from September to February in the southern hemisphere. It grows on all continents and requires fertile and fairly moist soils.

Basically, tobacco can grow in any place, where there is warmth and at least 100 free-from-frost nights, as cold and too much water makes the plants thin and weak. Additionally, the range of temperature for tobacco to grow efficiently varies depending on the region, however, it differs from 18-25 oC to 20-30 oC. As mentioned earlier, there are various tobacco plants cultivated and the main causes behind it are different types requirements and the reasons tobacco is sourced for.

The most popular one is Nicotiana tabacum which has various groups of leaves:

  • Lugs: the lowermost 4-5 leaves
  • Cutter: middle leaves
  • Upper-stalk: leaf and tip

What is worth noting, the higher the leaves, the higher the nicotine concentration in them.

The world’s nicotine demand is mostly supplied by China. In 2020 this country was leading, when it comes to sourcing tobacco, with over 2 610 000 tons of tobacco per year. Second, came India with over 800 000 tons, and was followed by Brasil with over 760 000 tons. After that, there was a big gap, as the 4th Zimbabwe produced more than 250 000 tons and 5th United States over 210 000 tons. Additionally, China and India, are also the two biggest nicotine extract manufacturers in the world.

Types of tobacco

The genus nicotiana has around 70 species, and each of them can be a source of multiple tobacco types. For example, multiple types of tobacco can be grown just from Nicotiana tabacum when one brings seeds to grow in a different place, with different factors – soils, weather, or harvest period. All of these factors influence the final tobacco properties, which include leaves’ size and colour, nicotine and sugar content, and consequently the taste. Additionally, each type can have various subtypes.

Below, we have described 3 of the most popular tobacco types, that are Oriental Tobacco, Virginia Tobacco, and Burley Tobacco.

Virginia Tobacco

Virginia tobacco has its roots in the decade of the XVII century. Then, the seeds of Nicotiana Tabacum were brought to the State of Virginia.

Depending on the time of harvest, the colour of the leaves may be light yellowish with high sugar content (early harvest) or darker, closer to orange with smaller sugar content.

Virginia tobacco can be flue-cured or air-cured. However, when flue-cured and the temperature is too high, the sugar turns into acid, consequently altering the taste that turns sharper and more irritating.

Virginia tobacco became popular as pipe tobacco and is one of, if not the most, popular tobacco types worldwide. Aside from the United States, Virginia tobacco is grown in Argentina, Brazil, China, and India.

Burley Tobacco

Burley tobacco is a bit younger than Virginia. It dates back to the second half of the XIX century when its seeds were brought to the State of Ohio.

Burley tobacco has white to yellowish leaves that turn darker brown during curing. Additionally, while curing, the existing sugar vanishes, which influences the taste that is dry. Moreover, the higher the leaf, the bolder the taste.

Burley tobacco often blends with other types, i.e., the aforementioned Virginia. Its role is to lighten the final taste of the mix. Moreover, compared to Virginia tobacco, Burley is also used as pipe tobacco and has almost the same content of nicotine, but thicker leaves. Moreover, this type of tobacco is grown in Argentina, Brazil, the United States, and Italy.

Oriental Tobacco

Oriental tobacco, also called Turkish tobacco, is grown in the Middle East, the Balkans, and Greece.

Compared to Virginia tobacco, it has much smaller leaves, but there are even three times more of them. Additionally, the nicotine content is smaller in Oriental tobacco compared to the previous two types.

During curing, some of the sugar remains in the Oriental tobacco leaves, which provides a sweet taste. Moreover, Oriental tobacco is often added to blends to bring a spicy note.

Drying tobacco leaves

When tobacco leaves are collected, they need to be dried. There are various methods, that apply to various species:

  • Air-curing: tobacco leaves are hung in ventilated, unheated sheds. They remain there until the colour turns light-brown or brown. By the end of the process, they no longer contain sugar.
  • Flue cure: heat enters the dryer through the pipes connected to a furnace placed outside. The colour range is from yellow to orange-red. Tobacco dried this way contains sugar.
  • Sun-curing: leaves are left for up to 30 days in the sun. Color varies from yellow to brown, and tobacco contains a lot of sugar. Sun-curing is the most popular among the 4 mentioned methods.
  • Fire-curing: similar to the process applied in smokehouses. Under the hung leaves, there are deciduous trees being burnt, which grants tobacco a specific smell.

When dried, tobacco is sorted by size, colour, and maturity. After that, the product is pressed into 30-80kg bales.

Leaves and dust – raw materials for tobacco extraction

After tobacco leaves are dried, they serve as raw materials in the process of extraction. Depending on the methods used, they are transformed into one of the two forms:

  • Tobacco dust, which is a name for tobacco leaves ground to powder
  • Shreds of around 2×2 mm, which the leaves were previously cut into

What is worth mentioning, after the process, used tobacco leaves gain another life.

Tobacco waste has multiple applications, especially in gardening and agriculture. It contains nitrogen, phosphorus, and potassium, which makes it a fertilizer, as the substances are of utter importance in the plant’s nutrition and enriching the soil. Moreover, tobacco waste works as a pesticide, as it contains nicotine, which is poisonous, if overdosed, to living organisms. Let us mention, however, that used tobacco leaves may not be widely known in various parts of the world, as it is often not sold commercially. Additionally, one has to be careful when using the substance. It doesn’t go in pair with every plant, i. e., tomatoes, and it may be dangerous for people. One should definitely not inhale it or use it with bare hands!

Extraction of tobacco

The next step in the process is extraction to which there are various methods, e.g., solvent extraction, dry extraction, maceration, acidification, neutralization, or supercritical extraction.

When it comes to the solvent method, as the name suggests, it is carried out using various solvents: water, alcohol, mineral oils, organic solvents, or acids. The first step is the maceration of the dried tobacco. Then, the product is collected, filtered, subjected to acidification, neutralization and then to evaporation, after which the crude extract is obtained. In the supercritical method, it is not solvent, but CO₂, which is used to separate nicotine from tobacco leaves, and dry extraction is about heating the material for extraction and acquiring a steam/smoke, which is then dissolved in, e.g. water, in a forced circulation using, e.g., a vacuum pump.

In every method, the result is the sameliquid nicotine extract. What is different, however, is the road the substance has to travel and the scale of its pollution.

Liquid nicotine extract final purification (distillation stage)

The next steps are purifying the crude extract and concentrating it. After that, distillation is done and the final effect is distilled nicotine with over 99% purity. These are the stages of the process. There are various methods of execution for each of them, that the manufacturer may choose from, to obtain the desired product. As examples, we can mention the single-stage long-time controlled process of fractional distillation or rectification – a multilevel distillation, where one acquires a pure product on various stages of the process.

In the last years, Chemnovatic has cooperated with more than 10 suppliers of both extract and pre-purified nicotine (nicotine with 90-95% purity) from outside Europe. Our experiences confirmed our belief that final purification is a key stage in the entire process and has to be done in our facility in Poland. It ensures product pharmaceutical grade quality and repeatability, especially taking into consideration the shipping to our European business partners.

Nicotine impurities

Although not much is talked about it, nicotine’s purity is one of, if not the most, important factors concerning the substance.

Nicotine’s purity mostly depends on the quality of the production process, which affects 2 types of impurities – natural impurities, such as tobacco alkaloids, and degradation products. These are the unwanted substances that appear during manufacturing, transportation, and storage, and can influence the efficacy of the product.

The case of nicotine’s purity is regulated by the US Pharmacopeia and the European Pharmacopeia. According to the definition, pharmacopeia is “an official list of drugs, containing binding standards for their composition, dosage, preparation, storage, as well as methods of testing their quality and evaluation”. Additionally, pharmacopeias also cover medicinal products, raw materials, and receipts.  In short, pharmacopeia is a reference point for chemical substances in the pharmaceutical industry and the primary source of information for chemists and pharmacists regarding the purity, quality, preparation, and application of chemical substances.

According to the European Pharmacopoeia, there are 7 specified substances the content of which must be test in nicotine. They are:

  • Cotinine,
  • B-nicotyrine
  • Anabasine
  • Nicotine-n’-oxides
  • Nornicotine
  • Anatabine
  • Myosmine

There can not be more than 0,3% of each of these substances in the chromatograph obtained results of nicotine’s purity. Additionally, there are also tests for unspecified impurities, which can not be more than 0,1%.

III. Nicotine distillation and quality assurance in Chemnovatic

In Chemnovatic, as one of the very few companies in Europe, we distill nicotine on our own. We use fractional distillation, where the distillation process is executed under lower pressure, which, consequently, lowers the boiling point, and nicotine’s, as well as the solvent’s evaporation temperatures. After that, the substance with a lower boiling point evaporates and becomes condensed in another vessel. Hence, the nicotine extract becomes purified. We repeat the manufacturing process until our product reaches a minimum of 99,5% purity.

nicotine distillation equipment

Having our own equipment, we have full control over this part of the process. Consequently, our PureNic 99+ is of the highest quality (pharmaceutical grade) and purity. When the distillation is finished the target products have to be stored. If you wonder what happens with the ready-to-use (for manufacturers) nicotine, you can read more about packaging and storing under this link. Let us add, however, that being located in Poland, the center of Europe, brings multiple advantages. May it serve as an example, that we can ship packages taking full responsibility for the product during the delivery to European clients and we provide full service of DGD, and IMDG shipments. We ensure quick delivery to European companies, which will not affect the nicotine products’ quality.

In 2017 Chemnovatic implemented the ISO 9001:2015, HACCP systems, and has been maintaining both certifications ever since. In 2021, Chemnovatic was successfully verified by the Intertek auditing company in the scope of: Supplier Qualification Programme (SQP) and Workplace Condition Assessment (WCA).

Keeping control over the external part of the process

We are constantly looking for and developing the source of each type of raw material, from tobacco extract to pre-purified nicotine, depending on the possibilities of suppliers and economic profitability. At the same time, we put emphasis on a stable and diversified supply chain in this area, making long-term contracts with suppliers whose reliability is proved with audits. Additionally, we focus on ESG practices that are of utter importance to us.

Each product manufactured by Chemnovatic comes with full documentation: material safety data sheet (MSDS), technical specification, and certificate of analysis.

4-Steps Quality Verification

Moreover, to ensure that our nicotine products are of the highest quality (pharmaceutical grade), we have developed the 4-Steps Quality Verification. The first stage is the inter-process laboratory analysis of each batch, which confirms the repeatability of the production process at its various stages. It is followed by laboratory analysis of each batch of the finished product. By that, we mean getting the full spectrum of EP compliance tests and others, in our in-house laboratory. Step number 3 is a multi-person panel assessment of the sensory aspects such as the smell and taste of each batch. The final stage is random confirmation of the results of internal tests in external accredited laboratories.

IV. Nicotine is a dangerous substance

Although we care about safety on each step, one always has to remember, that nicotine is a very dangerous substance. Especially in pure, undiluted form, and there are various ways of its absorption. The fastest is through the lungs, and a bit slower by the mucosa of the nose and mouth. What is also essential, is the absorbed source. The more alkaline it is, the easier the absorption.

Let’s state here also, that as harmful as e-liquid vaping may be, it is still less dangerous than smoking traditional cigarettes.

Many manufacturers of e-liquids or pouches decide to use nicotine base (nicotine diluted in PG/VG) instead of using its pure form. It is much easier to handle and carries less risk. Read more about nicotine handling, storing, and delivery conditions here, and be sure you do what’s necessary to satisfy your customers’ needs.

Signs of poisoning

When one is exposed to liquid nicotine, poisoning symptoms may occur. Among them, there are: nausea, vomiting, stomach pain, and severe dizziness. In the next phases salivation, blood pressure, and heart rate may be increased. In the worst case, intoxication may be fatal. Hence, keep in mind, that a lethal dose for adults may be 6.5-13 mg of pure nicotine/kg of body mass.

There may be various dangerous situations connected with nicotine:

  • If it’s poured on one’s skin, remove contaminated clothing and clear the skin with plenty of water with soap.
  • When the substance meets the eyes, was them with their eyelids open for 10-15 mins.
  • In case one ingests nicotine, do not force vomiting, just rinse one’s mouth with water, and if they lose consciousness, do not make them drink anything!
  • If there are nicotine fumes, cut off the source by removing the substance to fresh air.

Green tobacco sickness

There is also a disease called “green tobacco sickness”, which refers to farming tobacco plants. People who are exposed to nicotine, which may be absorbed through skin, and cause intoxication. The most common symptom, in this case, is weakness, followed by nausea, vomiting, and dizziness.

Nicotine and smoking tobacco

As mentioned earlier, vaping is less harmful than smoking tobacco. Absorbing nicotine, especially from traditional cigarettes, also has long-term effects. Tobacco leaves contain around 3800 substances that grow to even 5000-6000 when combusted. Around 100 combustion products are harmful and contribute to developing lung cancer, emphysema, cardiovascular disease, and more. Among the 100 there are: carbon monoxide, arsenic, and radioactive polonium-210.

According to Public Health England, when comparing e-cigarettes and traditional ones, there is at least 95% risk reduction when it comes to vaping.

V. Nicotine applications

Recreational purpose (i. e. e-liquid)

However dangerous, nicotine has a wide range of usage. The first, that comes to mind is a recreational purpose. For many smoking or vaping is pleasurable. Nowadays, there are various forms of absorbing nicotine – e-cigarettes (e-liquid), cigarettes, nicotine pouches, nicotine toothpicks, plasters, and more. Smoking cigarettes is the most harmful way of nicotine consumption as well as most popular worldwide. The other forms, including e-liquid, are often chosen by customers as a way to quit smoking accordingly to the Tobacco Harm Reduction concept.

Nicotine in medicine

Another example of the use of nicotine is the medical branch. As mentioned earlier, when smoking tobacco, there are around 100 harmful substances, that appear during combustion, and it’s commonly known, that smoking is harmful. Hence, nicotine may help give up on cigarettes. When one tries to quit, withdrawal symptoms may appear. In that case, nicotine may come helpful, to reduce the symptoms of withdrawal. To help complete the task, nicotine may be delivered to the body through nicotine patches, lozenges, sprays, and inhalation cartridges as they provide controlled levels of nicotine and there is no combustion.

Back to the fields – agricultural usage

Last but not least, we are back to square one – the natural environment. Nicotine is produced by some plants in order to scare away herbivores. Low doses are toxic for insects, preventing the plants from being destroyed by pests. Hence, nicotine is often used in the agricultural industry as a pivotal compound of insecticides. Consequently, farmers often reach for nicotine-containing products to protect their cultivations.

The use of nicotine in insecticides changed a bit in 2014 when the regulations made such products banned from the United States and the European Union. Nowadays, farmers use neonicotinoids, which are derived from nicotine.

VI. Summary

The story of nicotine dates several centuries back and begins in South America. Although the substance is used by millions worldwide, it has to be treated carefully from the very first touch. Even farmers shall be careful, due to the “green tobacco sickness”, let alone manufacturers, who work with it in pure, undiluted form. In case there are any signs of poisoning or you just feel worse after contact with nicotine, don’t hesitate to contact a medical doctor!

Nicotine is derived from tobacco plants, among which Nicotiana tabacum is the most popular. After sourcing it is dried and subjected to extraction, followed by purification. For all these steps, there are various manufacturing methods.

Similarly, there are various methods for nicotine intake: recreational products, such as e-liquids or nicotine pouches, or medical products such as nicotine patches. One should also keep in mind, that vaping does not equal smoking cigarettes, but is still harmful. The difference is in substances created when tobacco is combusted, which does not happen in e-liquids mist.

To sum up, dangerous as liquid nicotine may be, when working with the substance, one should always follow the procedures and improve safety protocols for both, pure nicotine and nicotine bases. Most of all, be sure of using high-quality raw materials.

Difícil de manejar, fácil de vapear: una cosa sobre el trabajo seguro con nicotina


a person with a safety uniform, half-mask, googles, and gloves, holding a clipboard, and a text: Hard to handle easy to vape, a thing about safe work with nicotine

Nicotine is omnipresent. E-liquids, e-cigarettes, nicotine pouches, nicotine patches, nicotine toothpicks, cigarettes, tobacco plants, and even some vegetables – are its carriers or sources. The substance is also present in medical products, which allows providing controlled levels of it to the human organism to help give up smoking. However, one should learn by heart – pure nicotine handling demands special safety measures.

Nicotine – introduction to the substance

The substance in pure form is highly perilous, and toxic, and may bring fatal consequences. Due to that, now we are going to take a look at nicotine handling, nicotine storage, health care, and dangers associated with working with nicotine in an industrial environment. 

If you wonder how the substance is produced, beginning from sourcing tobacco, and ending up in pure liquid form, make sure to check the story of nicotine and its production.

Keep in mind, however, that even in less purified form nicotine may be poisonous. An example of such a situation is the green tobacco sickness described later in this article. Also remember, that nicotine should not be worked with in a private environment, without specialized education, and professional equipment! Even one 500 ml bottle may kill hundreds, if not thousands, of people in the nearby area if handled improperly.

3 bottles: nicbase nicotine base, nic&salt hybrid base, nicotine free base, a text: haven't you tried our e-liquid bases yet? and a button: try now!

Nicotine sources

Before detailing safety measures, let us say that nicotine is a substance found in various plants and vegetables: eggplants, tomatoes, peppers, and more. In these examples, its concentration is negligible compared to the most known source – Nicotiana tabacum – the most common species of tobacco. The substance is present in the plant’s leaves and, when farming or sourcing, may cause a disease called “green tobacco sickness” because of direct contact with farmers’ skin.

Smoking and vaping comparison

Nicotine is highly associated with smoking, and as stimulating as this process may be, it is also unhealthy. Fumes of combusted tobacco contain around 250 toxic substances that are officially acknowledged as harmful. On the other hand, vaping is estimated to be 95% less harmful, and contributes to the tobacco harm reduction concept, and allows controlled nicotine intake, which may help with cigarette withdrawal symptoms.

Note, however, that if one does not vape, we do not recommend starting it, and now let’s focus on the dangers that stem from the substance in an industrial environment.

The dangers of working with nicotine

How to act when nicotine is set on fire?

Firstly, let us state that nicotine set on fire is a situation that should never happen! Under no circumstances! Unless it is for training purposes of firefighters’. However, if such a situation takes place, it means that somebody made a critical mistake by not developing crucial safety procedures, forming them incorrectly, or neglecting them.

When it comes to nicotine one of the safety measures is preventing it from ignition sources. However, if that happens and the fire starts, there are methods to extinguish it. Among the suitable media, there are:

  • CO2
  • Sand
  • Dry chemical (powder)
  • Water spray
4 plates presenting extinguishing measures to use when nicotine is set on fire: sand, CO2, dry chemicals, water spray

If you struggle with burning nicotine, remember to adapt these media to materials in the surroundings. Additionally, under no circumstances use a water jet. It may cause a risk of propagation of the flame.

Specialist firefighter equipment

Moreover, firefighters should wear protection typical in case of fires and not stay in fire-endangered areas without special, resistant clothingself-contained breathing apparatus, and suitable respiratory gear. Additionally, containers with water are to be cooled down from a distance to prevent them from breaking and spreading the liquid.

Nicotine, when burning, may produce toxic fumes of carbon and nitrogen oxides, so one must not inhale it. Additionally, the substance is toxic for aquatic organisms and may cause long-term effects in such an environment.

How to act when nicotine meets the eye

Nicotine is a highly toxic substance that can have even fatal consequences. When one comes in contact with it, they should take definitive measures to minimize the dangerous outcomes and preserve health and lifeWhat’s essential is the canal through which nicotine is absorbed:

  • If nicotine is poured on one’s skin, immediately take off contaminated clothing and wash the skin with plenty of water with soap.
  • In case nicotine meets the eyes, wash them with plenty of water with the eyelid held open, and keep up the process for up to 10-15 minutes.
  • When nicotine ingestion happens, do not force vomiting. One shall rinse their mouth with water. If they are unconscious, do not give them anything to drink.
  • If one inhales nicotine fumes, cut off the source by removing it to fresh air and keep warm and calm.

The acute toxicity estimate and the nicotine poisoning symptoms

The acute toxicity estimate doses for nicotine intake are:

  • Oral: 5 mg/kg
  • Skin: 70 mg/kg
  • Inhalation/mist: 0,19 mg/l

When one comes in direct contact with the substance, the following symptoms may occur: burning in the oral cavity, throat, and stomach, exhaustion, seizure, worsening of respiration, irregular heartbeat, impaired motor coordination, and coma. Additionally, chronic nicotine poisoning may lead to cardiovascular disorders.

Remember that in every case you come in dangerous contact with nicotine, you should consult a medical doctor!

Working with nicotine

If you are interested in how nicotine is sourced, extracted, and produced, read more about the process of manufacturing nicotine. It, however, concerns production. Now, let’s take a look at handling the substance in an industrial or laboratory environment.


Various safety measures are required when working with chemical substances.

The first group is collective protection measures, which means an employer has to equip the room where one works with nicotine with ventilation or fume hoods. Additionally, there must be a sink and an eye washer. Moreover, working alone is forbidden, and there always has to be assistance. There is also one more guideline that concerns the highest allowed concentration of a chemical substance in a workplace. On a daily and weekly scale, national law regulates it. It must not be exceeded due to the short- and long-term health consequences.

Now, let’s move on to the second group of safety equipment which is protective gear for working with nicotine. Keep in mind, however, that the norms mentioned below concern countries in the European Union. For different regions of the world, various administrative bodies and documents regulate these standards.

a text: Safety first! and 5 icons: gas mask, half-mask uniform, gloves and boots

Nicotine safety gear – Uniforms

This part of safety gear covers most parts of the body and is necessary. Although they do not cover faces or palms, other parts of safety equipment complement them.

Safety uniforms are regulated by Standard EN 14605, which concerns protective clothing against liquid chemicals. It specifies performance requirements for uniforms with liquid-tight (Type 3 protection class) and spray-tight (Type 4 protection class) seams and also concerns apparel that only partially protects the body.

Uniforms compliant with the aforementioned standard must also go in pair with EN 340:2003. It describes general requirements for protective clothing, like having no adverse effect on health or causing no skin irritation.

When buying uniforms for our employees, we consider paying attention if the clothing protects against the dangers mentioned in the table:

table with types of dangers uniforms protect against and icons of the predicaments

Nicotine safety gear – Gloves

It is hard to imagine working on nicotine without using your hands. That is why wearing special gloves is an absolute must! As for gloves’ size, the main requirement is they have to cover the wrists. Additionally, there are 3 types of them, according to EN ISO 374-1:2016:

  • Permeation resistance type A: resistant to at least 6 tested chemicals for at least 30 minutes each. Protection: ABCDEF
  • Permeation resistance type B: resistant to at least 3 tested chemicals for at least 20 minutes each. Protection: ABC
  • Permeation resistance type C: resistant to at least 1 tested chemical for at least 10 minutes each. This type, however, does not fully protect against nicotine. Protection: C

Below you can find substances against which the gloves protect. Let us add, however, that all gloves must protect against micro-organisms, bacteria, and fungi.

a table with types of gloves from A to F and the subtances they protect against

Nicotine safety gear – Boots

One cannot forget about protective boots. Working footwear may be associated with construction sites due to the fact they have characteristic impact-protection pads. However, there are also types of footwear that protect, i. e., against liquid penetration.

EN ISO 20345:2011 standard describes safety footwear requirements. Under this norm, safety boots have to protect feet against 200-joule impact.

Moreover, one can separate 2 classes regarding safety footwear material:

  • I – leather and any other material, except all-rubber or all-polymeric
  • II – All-rubber or all-polymeric

Additionally, to work with the nicotine, the footwear has to be of category S3, or in justified cases, one can use S5 / S6 category galoshes or footwear protectors.

  • S3 – protect against water penetration & absorption; energy absorption of seat region; fuel & penetration resistant; closed seat region, cleated outsole
  • S5 – aforementioned feature and: antistatic properties & leak-proof

Nicotine safety gear – Masks

Masks protect internal organs, especially the lungs, by saving one from inhaling the nicotine fumes but also cover the face. If it’s a full mask, it also covers the eyes.

There are various protective masks on the market. They are applicable in two versions: full-face gear or partially-covering masks. In Chemnovatic, we use both – full face masks that meet the requirements of EN 136:2001 Standard and half-masks that are compatible with EN 140:1993 Standard.

Safety masks’ classes

When it comes to full-face masks, there are 3 classes:

  • Class 1 – concerning light duty and low maintenance
  • Class 2 – concerning general duty, with maintainable parts
  • Class 3 – concerning heavy-duty firefighters

As mentioned before, half-masks are also acceptable when working with nicotine. However, when used in negative pressure systems, they may require filters compliant with the norms: EN141, EN143, EN371, or EN372.

Additionally, remember to wear protective goggles when using half or partially-covering masks. The norm EN-166 describes their requirements.

Visiting the production plant and/or the laboratory

Not only people who work with nicotine should care about safety. Every company that deals with dangerous substances should have safety procedures for people who visit the production plant or laboratory.

In Chemnovatic, if a third party is about to visit our production site or lab, they must wear a special apron, cap, gloves, and shoe protector. Additionally, there is a supervisor/guide ready to help at any moment.

Such procedures are there not only for the safety of the visitors but also for the safety of employees and the safety of the products. Wearing caps or protectors prevents dirt or hair from contaminating the area where lab technicians work with nicotine and other nicotine containing products.

Additionally, if you happen to visit a chemical company, be sure not to neglect any procedures, and if any doubts arise, ask the competent person about the safety requirements.

Fear not! Your product is safe

Due to nicotine’s toxicity, it requires special measures to provide safety all around. We care about every, even the smallest, detail, so our clients receive untouched products, and nobody gets harmed during the delivery. In order to do that, we use a special security seal. Moreover, our PureNic 99+ label has all essential information on it, along with a QR code for Safety Data Sheet and warning symbols.

There is also a batch number and best-before date printed on the bottle. Our shipments contain a Certificate of Analysis inside and Safety Data Sheet on the outside in the paper version.

To prevent any leakage, we use styrofoam packaging for 1-liter bottles, and everything is packed into plastic bags and secured with Chemnovatic tapes. For safety reasons, we add absorbent mats and extra paddings. Everything sums up to packaging compliant with UN standards.

Keep in mind that the containers in which you receive our PureNic 99+ are also for storing the remainings. However, when you use the products, dispose of them in accordance with the local legislation, and under no circumstances empty the packaging into drains!

As for disposal, reuse, recycling, or liquidation of used packaging – follow the legal guidelines. Do not dispose of empty nicotine packaging with regular household waste, and do not mix them with other waste.

Quality Verification

Before bottling nicotine, we make sure that the product you buy from us is the best and of the highest quality. To ensure it, we have developed and execute the 4-Steps Quality Verification, which you can learn in the graphic below. Also make sure to read more about our quality and standards.

Storing nicotine

Another very essential aspect of launching pure nicotine to the market is storing it. Various conditions should be met when bottling nicotine, storing it before the first opening, and storing it after the opening.

We have described the process of handling and storing pure nicotine and nicotine salts, so don’t hesitate to learn more about it!

The benefits of nicotine

Although nicotine is a dangerous substance, if handled properly, it may bring a great number of benefits. Nicotine-containing products, such as nicotine pouches or e-liquids, may help people who smoke deal with cigarette withdrawal symptoms. Additionally, according to Public Health England, e-cigarettes are much less harmful than traditional smoking, and vaping nicotine-containing products may be a great alternative for people who try to quit smoking.


Although nicotine is a very dangerous substance, it is not only to be tamed but also handled. One simply needs to remember not to neglect the safety protocols and, in case of danger, follow safety procedures. Also, it is essential and better to prevent the danger, than fix its effects. That’s why we have developed and are constantly improving safety measures and standards. Thanks to that, our employees feel safe in their working environment. To prove that, our company has been awarded the Workplace Continous Assessment certificate by Intertek.
