DuraTrue Testing



With the uniqueness of DuraTrue, our tobacco extract eliquid, we feel it's very important to be as transparent as possible with what it is, and what's in it. In order to provide you with the best information possible, we had an outside company, Enthalpy Analytical, Inc perform puff tests on our product DuraTrue, and compared them to previous test results from a cigarette puff testing trial.

**Please note: These results have nothing to do with our other eLiquid, DuraSmoke. These results are from a seperate product, DuraTrue, which is made from tobacco. In no way does the information below reflect outcomes from any other product we manufacture.

 We chose a puff test because we wanted to have a test that would give results based on an equal playing field. Also, testing the liquid only, would not be conclusive enough as the liquid is vaporized and inhaled. A puff test best analyzes the levels of numerous ingredient particles that are found in the vape clouds and cigarette smoke when inhaled/exhaled.  

The test results below are grouped into categories. Our on staff, Ph.D. Chemist, Dr. S.A. Pace will explain the data in more detail, and provide expert analysis on the product and the results. Keep in mind that these test results are only for DuraTrue. DuraTrue is an extract eLiquid that is made in a completely separate way than our DuraSmoke eLiquids. DuraTrue is also made in our ISO 9001:2008 registered facility, but made from actual tobacco leaves. 


Here are the results of the DuraTrue puff tests:




 It is well known that cigarette smoke is a complex mixture of chemicals and chemical reaction byproducts.  Recent TV advertisements suggest that cigarette smoke contains some 7000 chemicals in varying concentration.  This total even appears to grow as new scientific instruments are developed to do the analytical testing with increasing sensitivity to trace amounts previously undetected.

It would be impractical here to individually discuss the amounts and physiological impacts of thousands of chemical entities in cigarette smoke.  However, we can compare some of the major or more significant components in smoke versus DuraTrue e-liquid vapor so that consumers can make informed personal decisions.

Let us consider four classes of chemical compounds that cover most of the components of interest to smokers and vapers.  These classes of chemicals include (1) carbonyls, (2) tobacco specific nitrosamines (i.e., TSNA’s), (3) phenols, and (4) other volatile organic compounds (VOC’s).  Some of these chemicals are native to the tobacco plant but others are essentially produced by hot gaseous reactions due to incomplete combustion.


Let's break it down further by category:



 The carbonyl class comprises a number of low molecular weight aldehydes and ketones.  Some examples include formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, acrolein, and acetone.  These aldehydes are just the 1, 2, 3, and 4 carbon-chain representatives of that family, with formaldehyde being the most familiar to people for its use in embalming.  Formaldehyde can also create indoor air quality problems when resin laminates (countertops, etc.) or insulations are improperly cured.  It is now classified as a known carcinogen.

Acrolein is also called propenal and is similar to propionaldehyde but with an unsaturated C-C bond.  It is mostly familiar as the acrid smell arising from the high temperature breakdown of fats in grilling (i.e., pyrolysis of glycerin).   Acetone is a familiar solvent in industrial processes and is responsible for “acetone breath” in dieters.

While none of these carbonyl compounds are desirable, the above graph clearly shows that DuraTrue vapor contains 100 to 200 times less carbonyl compunds.                                                                                                                                                           



Next consider the TSNA nitrosamines: N-nitrosonornicotine (NNN), 4-methyl-N-nitrosamino-1-(3-pyridyl)-1-butanone (NNK), N-nitrosoanatabine (NAT) and N-nitrosoanabasine (NAB).  These compounds are formed from nicotine during the curing process of tobacco leaves. 

They are also considered as one of the more important groups of carcinogens in tobacco products, with the first two (NNN and NNK) being viewed as important actors in oral, throat and lung cancer.  NNN and NNK are metabolized to highly reactive electrophiles which react with nucleophilic centers of DNA.  However, personal sensitivity to these chemicals may be related to a wide variability in metabolism rate by individuals.

Again referring to our comparison graph, we see a 16 to 62-fold reduction in TSNA concentration for DuraTrue versus typical cigarettes.       



Volatile organic compounds are typically chemicals of low molecular weight that have low boiling points, usually below 100C, and cover an extensive range of chemical families, both aliphatic and aromatic.  They easily evaporate or are naturally gases at room temperature.  Some examples relevant to cigarette smoke include chemicals such as 1, 3-butadiene, isoprene (AKA 2-methyl 1, 3-butadiene), benzene, and toluene.  The first two are familiar as the monomers that can be polymerized into rubber.  Benzene and toluene are common industrial solvents, with benzene being a known carcinogen.

These particular chemicals, along with others of the class, are pyrolysis degradation products from the burning of tobacco.  As such, it is not surprising that our graph shows DuraTrue being free from these contaminants.                                                                                                         



Other less volatile aromatic derivatives of benzene are also of interest.  In particular, such chemicals as the cresols (ortho, meta, and para isomers) and phenol have been found in cigarette smoke.  These compounds are also components of creosote, the familiar tarry soot formed from poor combustion of wood in fireplaces.  The creosols are considered as irritants when breathed at low levels, or higher levels for a short time, but less is known about chronic exposure. 

Once again, our graph demonstrates that DuraTrue exhibits no detectable levels of such chemicals since vaping does not require high temperature combustion                                                                                              


More extensive and detailed studies of cigarette smoke are available in the scientific literature for those who are interested.  However, this short comparison clearly demonstrates that vaping DuraTrue offers distinct advantages over smoking cigarettes. 

DuraTrue provides the same full natural tobacco flavor experience without some of the drawbacks inherent in cigarettes. 

So what does all this mean for you, the user?

This backs up our claim of DuraTrue being a breakthrough product for the industry. Not only do you get the same taste as a cigarette, but you get it with 99% reduction in contaminants. That's right... there is less than 1% of the same contaminates in DuraTrue than in cigarettes. DuraTrue also comes at a fraction of the price of a pack of cigarettes. One 15mL bottle is equivalent to 15 packs of cigarettes.

Just like any other eLiquid, DuraTrue is not a healthy option... it is a healthier alternative to smoking. With fractions of contaminants at a fraction of the price, DuraTrue is just a smarter choice over cigarettes.
