Aroma Ingredients and Mixing Ratio

By frequent inquiries of the material list for flavours you find a list under the following link.
We are constantly working to remove negative substances from flavours.

Aromaliste - Ingredients

It is well known that tastes are different. Therefore, we recommend starting with a concentration of 1-3% for tobacco and 5% for the remaining flavours - but max. 15%.

For our HK flavours (highly concentrated flavours) we recommend starting with 0.5-1%.


1,2-Propanediol (propylene glycol) - E 1520

Also known as propane-1,2-diol. Has a good ability to dissolve aromas, also has a preservative effect in higher concentrations. Also antifreeze, solvents for paints, brake fluid, for the production of plastics, humectants for tobacco and cosmetics. Is immediately absorbed by the body. Considered harmless in small doses, even if skin rashes were occasionally observed.

Benzyl alcohol - E 1519

Also known as benzyl benzoate as a dimer. Naturally found in jasmine blossom oil, fruits or green tea. Extraction and dissolving agent for aromas as well as aroma substance with light aromatic smell and preservative effect.

Glycerol triacetate (triacetin) - E 1518

Colourless, oily liquids. E 1518 is a natural ingredient of papaya. In chemical synthesis, both substances are usually obtained simultaneously, so that they are often used as a mixture. Use mainly for aromas and natural extracts, as well as chewing masses.

Since E 1518 not only tastes sweet, creamy and fruity, but also has a moisturizing effect, it is also used as a plasticizer for plastics and as a solubilizer for paint, textile, paper and leather treatment agents.
Substances from Makrolon are not triacetin (E1518) resistant.

Makrolon (polycarbonate)

These tank systems have the advantage that you can see how much liquid is still in the tank. However, these tanks can be eaten away by the additive (even creepingly) and literally crumble! The reason for this is that plasticizers are removed from the plastic (by liquids). It has been shown that Makrolon (the tank) which has been heat-treated is more resistant than untreated Makrolonist.
You can read a good overview about the chemical resistance of plastics among others also the substance Makrolon here.

Butylhydroxyanisole (BHA) - E 320

Synthetic fabrics. BHA (E 320) has a preservative effect. E 320 and E 321 protect snacks from taste falsification, stabilise flavours, frying fats, chewing gum, instant soups and increase the shelf life of marzipan, cake mixes and food supplements.

Nicotine base calculator

The nicotine base calculator gives you hints on how to calculate nicotine-containing bases to your desired strength.

  • Field 1 defines the maximum nicotine level
  • Field 2 defines the minimum value of nicotine
  • Field 3 defines the desired nicotine content
  • The initial quantity defines the desired quantity.
  • Finally, the right column provides information about the ratio to be mixed in ml.

General information

Instead of conventional cigarettes, electric cigarettes do not burn tobacco, but evaporate an eLiquid. The content of an eLiquid consists of a basic mixture to which aromas and, if necessary, nicotine are added.

Ingredients and mixture

The ingredients for the basic mixture are propylene glycol (PG) and/or pure vegetable glycerine (VG). It is also used in place of PGs polyethylene glycol 400 (PEG). When PEG is used, the liquids become less sweet in taste. Few people have a slight incompatibility with PG (e.g. neck scratches) and in this case can switch to products with PEG.

Our my-eLiquid products without nicotine content do not cause any health-endangering effects according to our experiences and the information available to us, if they are handled properly and used as intended.

The relationship between PG, VG and PEG in the basic mixture has a decisive influence on steam development and also on the sweet taste of the eLiquid. PG, VG and PEG are viscous. In order to influence viscosity, water or neutral-tasting spirits are generally added. Liquids that are too viscous start at the evaporators and influence the functionality and above all the taste.

my-eLiquid offers you the ingredients PG, VG and PEG 400 in pharmacopoeia quality under the category, DIY (do ityourself). We also use these articles ourselves for the production of our eLiquids. We purchase the products from German pharmacies or from German fine chemicals wholesalers. Furthermore you can choose between products without nicotine as well as products in numerous, different nicotine contents and/or nicotine strengths. In the articles of my-eLiquid tested, pharmaceutical nicotine is used.

The pure nicotine is a poison and is classified as very toxic. If the necessary qualifications and permits are not given, the procurement and handling of pure nicotine is strongly discouraged, as it is irresponsible and can also be a criminal offence.

The flavors are food flavors or tobacco flavors and should not contain oils, fats or sugars, as these can damage the vaporizers in the electric cigarettes as well as dyes.

My-eLiquid exclusively uses tested flavours which comply with the following principles from an association of manufacturers:

It is the responsibility of the Association to promote and protect the general and common ideological, economic, legal and socio-political interests of its members.

The association shall in particular

  1. accompany and promote legal developments at national, European and international level as regards flavourings (essences), functional food ingredients and products derived therefrom;
  2. represent the interests of the flavour industry vis-à-vis authorities, organisations and associations;
  3. coordinate and promote the exchange of general economic and technical information within the flavour industry;
  4. for fair competition in the flavour industry.

The association is a member of the European Flavour Association (EFFA) and the International OrganizationoftheFlavorIndustry (IOFI).

The purpose of the association is not to conduct economic business.

These flavours are used in food production or the tobacco industry and have the relevant approvals and our trust.

Storage and handling

The eLiquids, whether with or without nicotine content, must be kept out of the reach of children and animals. The nicotine content is expressed in mg/ml. The less body weight a living being has, the more dangerous the oral (e.g. swallowing) or dermal (through skin contact) intake of toxins such as nicotine is to health or life.

This rule also applies to tobacco cigarettes.

On the product labels of my-eLiquid you will find all medically necessary information.

In case of unwanted physical absorption, show this information to your doctor.

In our experience, you should not expose your eLiquids to constant sunlight and store them in a cooler place if possible. The refrigerator is not a must, but is recommended if you want to store your eLiquid longer.

The aromas in the eLiquids lose their flavour volume due to frequent temperature fluctuations.

We also recommend using up opened eLiquids in the following weeks. Otherwise they may lose their taste volume more quickly than full or unopened bottles.

After use, the bottle should be closed again soon to avoid loss of aroma.

Avoid too long exposure to sunlight and unwanted heat.

If handled properly, eLiquids can last for more than one year. In terms of colour, the various eLiquids are slightly yellowish, brownish or colourless. But make sure that the liquid is clear.

Steaming from A - Z



People with a food allergy can also be allergic to the corresponding natural aroma (for example, natural hazelnut aroma in a hazelnut allergy).
Furthermore, an allergic reaction to a carrier substance is also possible, albeit rather rare. Certainty as to whether you are allergic to a specific aroma can only be established by a special allergy test carried out by an allergologist.


Flavourings are products which are not intended to be consumed directly but are added to foods to give them a specific smell or taste. Depending on the origin and method of extraction, aromas are divided into six categories: flavouring substances, flavouring preparations, thermally produced reaction flavourings, smoke flavourings, flavouring precursors, other flavourings or mixtures thereof. At this point we would like to deal with the terms aroma substance and aroma extract in detail.

The term aroma substance simply describes a chemically defined substance. This does not say anything about its origin. If it is produced chemically, it is called an artificial flavouring. It does not matter whether this aroma substance was inspired by nature or "reinvented".
Natural flavourings, on the other hand, occur in nature and are obtained from plant, animal or microbiological raw materials. Not only must the raw materials satisfy special requirements, but also the extraction process used to obtain the flavouring. The
definition of a flavouring extract is very similar to that of natural flavouring substances, but does not designate a single defined substance, but may include several natural flavouring substances.

The term "natural" may only be used in connection with flavourings for flavouring extracts and/or natural flavouring substances.

Diacetyl is a chemical compound that is used in various foods due to its intense butter flavour. Diacetyl is suspected of causing bronchiolitisobliterans, a rare respiratory disease. The basis for this assumption is the frequent illness of workers in popcorn factories in the USA, who were regularly exposed to intensive diacetyl fights.
Whether such a danger also comes from small quantities is at least questionable. However, many aroma manufacturers avoid the use of diacetyl as a precautionary measure - including the manufacturers managed by us.

Diacetyl on Wikipedia

(with further evidence)

my-eLiquid completely dispenses with aromas containing diacetyl.


A general rule of thumb for dosage is unfortunately not possible. Not only are tastes very different, the aromas themselves also differ greatly in their concentration.

For more information see: concentration



Ethylmaltol is usually used as a crystalline, white powder and as a flavour enhancer gives food a more intense taste. Sweetness is perceived sweeter and fruits fuller. In this function it can also be used in liquids. Alone, it's most reminiscent of cotton candy. In combination with other flavours it can be used for rounding off and sweetening.

E-Cigarette Flavors

Suppliers who are marked with this logo are manufacturers who produce flavors especially for e-cigarettes. These vendors are mostly only since the spread of e-cigarette on the market. Their flavors are designed for use in e-cigarettes and are usually particularly suitable for this area.

Conversely, these manufacturers certainly lack the experience and knowledge in the classic food sector.

glass containers

Plastic bottles undoubtedly offer a wealth of advantages, among others they are not fragile, extremely cheap and have a very low weight.

However, there are clear disadvantages. Unlike glass bottles, plastic bottles are not gas-tight. This means that the content interacts with the circulating air, but also with the plastic itself. As a result, the aroma loses intensity over time. Furthermore, plastic can release substances into the contents, which can lead to an additional falsification of the taste.

In order to guarantee the best possible taste experience, we do not use plastic as much as possible in favour of glass, so that the taste is not falsified or weakened even at the customer's after a longer storage period.

For the sake of completeness, it should be noted that there are different voices which classify plastic bottles as not harmless to health.

The concentration or intensity of flavours varies greatly from manufacturer to manufacturer. Experience gained with one supplier cannot therefore be easily transferred to others. Even flavours from the same manufacturer can differ significantly in their strength.

In addition, tastes are of course different. What is too weak for one person can already be much too intense for another. Caution is also called for with regard to experience from other cultures - Americans, for example, generally prefer far more intensive products than consumers in Europe. 1:1 transfers could therefore lead to undesirable results.
Finally, the liquid base can also lead to different results. For example, aromas are more effective in propylene glycol starch than in glycerol.

As a rule, it is therefore advisable to start low and, if necessary, increase the quantity in small steps until the desired taste is reached.


food aroma

With the exception of a few tobacco flavours extracted from tobacco leaves, the flavours offered are food flavours, which are often used in finished products. These flavourings are authorised for use in foodstuffs.

Nevertheless, we distinguish between manufacturers who come from the classic food sector and those who have developed with the spread of the e-cigarette and have specialized in the field of "flavors for e-cigarettes" from the beginning.

Although these suppliers also use food flavourings, we advise against baking and cooking them and recommend classic food flavourings. E-cigarette flavors have been developed for use in e-cigarettes and knowledge and experience of these manufacturers are limited to steaming.

The fact that our flavors are food flavors should not hide the fact that inhalation (when used in e-cigarettes) is not the same as ingestion via the tube. So far, there are no reliable findings as to whether and to what extent inhaling aromas is harmful to health.



Menthol is mainly obtained from peppermint oils and is used in food, cosmetics or pharmaceuticals due to its refreshing and cooling effect. At room temperature, menthol is present in crystalline form. Dissolved in propylene glycol, such menthol crystals are ideally suited for the production of a very intensive menthol liquid.
Warning: Highly concentrated menthol is highly irritant - therefore, care should be taken to avoid high concentrations in the finished liquid. Unfortunately there is no reliable information on the question of which concentration is to be classified as dangerous.

Natural flavours

It is controversial whether natural flavours are better suited to steaming than artificial flavours. As they are of natural origin, this could be assumed for the time being. However, natural products, and thus the flavourings derived from them, consist of a variety of chemical compounds, whereas artificial flavourings are usually composed of a small number of (highly effective) components. Some therefore believe that "it is better to inhale a few substances than a large number of compounds" - even if the latter is a natural aroma".


Oil-based Flavours

Oil-based flavors are usually not recommended for use in the e-cigarette. There are users who also use these with reference to the low final quantity in the liquid. However, the overwhelming majority of steamships are of the opinion that oil-based flavours should be avoided.
It is argued that oils can form unwanted by-products when heated in the evaporator and that oil in the lungs can also have unpredictable consequences. As always, these are only guesses. However, as there are enough alternatives, oil-based flavours appear to be an unnecessary risk.
In addition, oil dissolves poorly in the liquid and thus oil-based flavors are also practically more difficult to handle.

See glass containers



Like many other things, the subject of maturation under steamships is also highly controversial. Some swear by it, others see it as a figment of their imagination. However, many users report that some aromas in the liquid actually become better or more intense after several days to weeks of maturation. The best advice we can give you in this context is therefore: try it out!
If you don't like the aroma, just leave it in a sun- and heat-protected area and try it again a few days later.



There are several ways to sweeten liquids. The most obvious way would be to add a different sweet aroma to the liquid to sweeten all the liquid in this way. The disadvantage of this, however, is that you not only get more sweetness, but also change the taste of the liquid. But that's often undesirable.
For this purpose there are different sweeteners, which differ slightly in detail, so that we would like to give a small overview here

Sucralose/ Sweetener

The product "Sweetener" is based on sucralose. Sucralose is a sweetener obtained from traditional household sugar that is up to 600 times sweeter than the latter. Sweetener is perfect for sweetening liquids. It is very concentrated and sweet excellent without changing the taste of the liquid.

Ethylmaltol/ Cotton Candy

Ethylmaltol is a crystalline powder that tastes like cotton candy dissolved in Propylengykol. This is therefore nothing more than diluted ethylmaltol: 10% ethylmaltol dissolved in propylene glycol.
Like sucralose, ethylmaltol also sweetens, but not nearly as strongly. But it does a lot more for that. It rounds off aromas and takes rough tones out of the taste.


Stevia is a sweetener extracted from Steviarebaudiana (also called sweet cabbage). It is up to 300 times sweeter than household sugar and has been approved in the EU as a food additive (E960) since 2011. Pure Stevia Powder, as we offer it, does not contain any fillers, as is usual with commercial Stevia products.
Stevia is in crystalline form and is dissolved in water or propylene glycol for easier dosing. Stevia is very sweet and does not change the taste of the liquid. It is therefore more comparable to sucralose than to ethylmaltol.

Which sweetener you use depends on your personal preferences. Many like the effect of ethylmaltol in their liquids, others just want sweets without taste changes. As far as suitability for steaming is concerned, none of the products have been developed or tested for steaming. Ethylmaltol and Sweetener, however, have been used much longer and by a larger number of steamers than is the case with Stevia. Conversely, supporters argue that stevia, unlike ethylmaltol and sucralose, is a natural product.


tobacco extract

Tobacco extract is obtained directly from tobacco leaves and is used, for example, in the cigarette industry for flavouring. However, tobacco extract has not been tested and approved as a food flavour.
Tobacco extract is a thick, highly concentrated, but nicotine-free aroma that can be used to produce tobacco liquid. For this purpose, it is first pre-diluted with ethyl alcohol or propylene glycol and can then be used in the usual manner. In order to give the liquid a slightly softer note, ethyl maltol is often added.

For more information and detailed mixing instructions see also:

Steam sign by Alex - Section Tobacco Absolute

carrier materials

In pure form, flavourings are highly concentrated and difficult to process. Therefore, they are usually dissolved in a carrier material. The flavours offered by us are propylene glycol, triacetine, ethyl alcohol and/or glycerine.
But these substances are also used for the extraction of the aroma substance from the starting material.


Triacetin is a compound of glycerin and acetic acid. It is approved in the EU under the number E1518 as an additive in flavourings and is classified as safe for food use. On the basis of experiments on rats, short-term inhalation is also considered to be harmless. Whether and to what extent it is less suitable for steaming than other bases such as propylene glycol is controversial.
Some do without it with reference to missing studies, while others see no higher risk in it. Still others find the Triacetin in the aroma as taste unpleasant.

Note: There are indications that triacetine-containing liquids may soften certain types of plastic.

Especially the plastic Makrolon is very susceptible to Triacetin, a use with untreated (tempering, heating, beading) Makrolon leads to a timely destruction.
An analysis for the additive triacetin on the subject of harmfulness will soon follow in the form of a cell biological study.

For risk assessment see also:

Final report on the safety assessment of triacetin.

Droplet size, milliliter & milligram

Our flavours always come in glass bottles with a drip tray to facilitate handling. However, drops are not suitable as a basis for measurement!

This is because the amount a drop contains depends on various factors. To be mentioned here are: the dropping insert, influences by tapping on the bottle lid and in particular the viscosity, thus the viscosity of the aroma - the viscosity depends again on the composition of the liquid itself, but also on its temperature. A generally binding statement as to how many millilitres a drop contains is therefore not possible.

If you want to measure the aroma quantity correctly, you must either weigh it in milligrams using a scale or measure it in milliliters using a suitable measuring vessel.

Please note the conversion from volume to weight.
If you are not sure, we will send you the technical data sheets with the information.
One litre of springs is not the same as one litre of lead!
A kilo of feathers, however, equals a kilo of lead.

The bet:

I can take it when you throw a gallon of feathers on my head from 10 meters up.
!!!!!!! >>>>>> With lead you will not survive <<<< !!!!!!!!

Of course, drops are still suitable for rough orientation. If you always take 5 drops of the same aroma with the same dropper, the accuracy will be sufficient for most requirements.


Additives (sugar, dyes,...)

Some manufacturers add further additives to their flavours. These include in particular dyes and sugar. Dyestuffs are usually added exclusively for the appearance.

Yellow vanilla or brown chocolate flavor sells better than crystal clear. Sugar, in turn, is added to sweeten the aroma.

We try to avoid additions as much as possible and to list them completely in the table of contents.

Sugar should be avoided for e-cigarette liquids, since on the one hand their inhalation represents an unnecessary unknown and on the other hand these substances can accelerate the wear of the evaporator.
