DISCLAIMER: This is for educational purposes only and is not intended to inform individuals on how to make liquid, rather to inform you exactly on the components of e liquid.

Broadly speaking we can not simply tell you every ingredient contained in any given bottle of e liquid, however we can go off of our intuition and 4 years of hands on experience creating professional e liquid.

I must add before we get too far, that the ingredients outlined in the context below are commonly known ingredients that are known to be used by e liquid manufacturers and flavor artists alike, not all (and not any beyond ingredient 4) will be found in liquid purchased at PrecisionVapeProducts.com , this read is intended to educate e liquid consumers on what may be in any given bottle of liquid, Should the manufacturer not provide insight.

Generally we are told that vaporizer liquid consist of 4 ingredients; Vegetable Glycerin, Propylene Glycol, Liquid-Nicotine, and flavoring. Now, as one could imagine with the hundreds of thousands of e liquid manufacturers out there doing as they please, it is safe to say that other ingredients besides these 4 generally accepted ingredients are being used in the manufacturing or e liquids.

without any further delay, let's get into this.

1. Nicotine:

By now, yes we all know this, but for those of you who do not, yes it is very probable that any given bottle of e liquid contains nicotine content. Nicotine will come in a world of different brands and qualities, and is essentially one of, if not the most important part of e liquid. Nicotine for e liquid is obtained from the distillation of tobacco leaves and is further purified by chromatography or further distillation to obtain potency and quality. Concentration of nicotine in solution is commonly referred to in two manners – mg/mL or by % (EXAMPLE: 3mg/mL would be equivalent to 3% while 15mg/ml is equivalent to 1.5%). Nicotine in its purest form is a colorless, pyridine-odored, non-viscous liquid. Concentrations of >100mg/mL must be dealt with using full Personal Protective Equipment (PPE), adequate ventilation, in a biohazard-zoned facility with proper biohazard disposal. Concentrations of 50-100mg/mL should be handled using low-level PPE (long sleeves, gloves, safety eyewear) along with adequate ventilation. Common nicotine concentrations seen in finished eliquids are seen ranging from 2mg/mL – 36mg/mL. Nicotine imparts a throat hit to e liquid, which is found to intensify as further nicotine content is added to the e liquid.

2. Propylene Glycol (PG):

Propylene glycol is one of the two common solvents that composes eliquid (along with VG). PG is a clear, odorless, fairly non-viscous liquid that is a very common solvent used in a range of medical aerosol devices, most commonly seen in albuterol inhalers. A common misconception with PG is Left in its purity. Many in the public have seen electronic cigarette use as harmful as a result of this solvent, claiming the use of an antifreeze as an ingredient., While they are correct, PG in a very unpure and unrefined grade, is used in antifreeze as a glycol to lower freezing boints and raise boiling points. However, in electronic cigarettes, the grade of PG used is much higher, free of the heavy metals and other unwanted contaminants present in low-grade PG. Food-grade or greater PG is used in e liquid, we here at Precision Vape Products only use the highest quality pharmaceutical grade of PG.In comparison to VG, PG is very non-viscous, and solvates nicotine extremely well, able to be mixed by hand in short amounts of time. PG also posesses a lengthier expiration date – 2 years – when stored in a cool, dry place. PG imparts a dessicating throat hit to eliquids in high %/mL as well as providing very high flavor solubility due to its low viscosity and lower molecular weight when compared to Vegetable Glycerin.

3. Vegetable Glycerin (VG):

VG is a colorless (or VERY light tan-opaque), odorless, very viscous liquid, the other common solvent used in eliquid (along with PG). When stored properly, in a cool, dry environment, VG will remain free from oxidation or degredation for one year. Most highly regard VG for its smoothness and large vapor production, and it is excellent in these two areas. However, VG lacks the robust flavor solubility that PG posesses, and has a quicker expiration date. In addition, with liquids containing VG, the vaper must be conscious to vape within range of VG’s flash point (348.8•F). Vaporizing eliquid is a function of atomizing eliquid at the flash point, and our goal is to hover around this temperature as the flash point of VG is the higher than both PG and nicotine. However, with VG, at the boiling point(545•F), carcinogenic acrolein is produced. This fact should be considered with vapers using rebuildable atomizers reaching high temperatures vaporizing high-VG eliquids. Please be cautious of your coils temperatures at which it vaporizes the e liquid substance.

4. Flavoring:

Flavorings differ vastly between e liquids, but are commonly extracted from natural sources by distillation, or synthetically prepared in the laboratory mimicing naturally-occuring substances. Carrier solvents commonly include PG, VG, water, and ethyl alcohol. Many flavorings are extracted under differing distillation processes, resulting in a wide concentration of end-products. While there are a wide range of food-based flavorings that would be seemingly appropriate for use in eliquids, the DIY vaper must be conscious of the hydrophobicity of the flavoring in question for health reasons. Water-soluble flavorings carried in PG, VG, ethanol or water are most commonly appropriate for eliquid use, due to their hydrophilicity. However, oil-based flavorings of a lipid source can lead to a condition deemed ‘lipid pneumonia,’ a result of continued buildup of lipids effectively suffocating the alveoli of the lungs. (This goes back to the first paragraph of the context where it was stated that you will need to do your research before possibly causing health risks to yourself, please do sufficient research on every aspect of DIY e liquid before attempting to create and then inhale your own e liquid substance🙂)

And here are a few additional ingredients we like to refer to as additives that are common to many eliquids, but are not part of the main ingredients list, and are not used at all in Precision Vape Product liquids, but we felt that you the consumer should know this as you could be a consumer of liquid bought from a vendor that contains the following.



Water:

Here at Precision Vape Products, we do not utilize water in our e liquids, however, many use them to assist in the lowering of viscosity in high-VG eliquids. When a smooth vape is desired, free of PG, water would be the additive of choice (rather than PG) to lower the viscosity of the solution. Distilled water must be used, as to avoid hard mineral deposits on atomizer coils and wicks.

Vinegar:

I know, it sounds absurd but there is individuals and e liquid vendors who actually utilize vinegar, it's said to give liquid an added pop. I am not eye to eye with this statement, but I will do my best to give you non biased breakdown of why vendors use vinegar. Vinegar itself is acidic by nature, any person who has taken a culinary class or dug into culinary education is familiar with adding acidity to a pallet and what is does for you.

Sweeteners:

By now you can surf the internet and find dozens of sweeteners, it's hard to accurately inform you on this additive due to the wide range of sweetening methods that can include any type of sugar or sweet substance. With no scientific basis to prove this claim, I strongly believe that sweeteners are a health concern, now there is accepted sweeteners and when used at correct percentages will pose no health risk, you can definitely tell when an e liquid is over sweet. Use your judgement to decide whether it's worth it to sacrifice the health risks for the flavor.

Salts:

Some use salts in their product. It's hard for me to explain to you what this may do as the search criteria in google has not shown me exactly what the effects of salts may do to e liquid.

Sours:

Ingredients that will give an e liquid a sour perception range from a wide assertion of "acid" ingredients, malic acid/citric acid/tartaric acid. We have experimented with these sour additives early in out e liquid manufacturing career and dismissed them due to a lingering and unpleasant throat hit in the middle of throats area. We concluded that using sour additives presents added health risk, again with no scientific basis, just common logic.

And that's it for the ingredient and chemical analysis of the substance we refer to as e liquid.

I covered as much as I could. And we are almost certain that somewhere someone is adding other additives but we've done out best to gather a list of the most popular.

by now you should be an expert on the makeup of e liquid. Thank you for your read and as always please share and if there is anything you feel is/was not covered in this context please send us a message and let us know your suggestion.
