ELIQUID and Testing

Eliquid is made with 4 basic ingredients.

The first 3 are food grade. Approved for use in food products and also in most of the daily products we use and ingest (cosmetics, personal hygeine, medicines, natural health products).
1. PG = Propylene Glycol
2. VG = Vegetable Glycerin
3. Selected Food Flavorings

The 4th ingredient is nicotine**.  and is considered "optional". Eliquids can be made with or without it and in varying amounts. The amount is part of a consumer's choice and, unlike cigarettes, you get to adjust the amount of nicotine you use during the day or over time, according to your individual choice and perceived needs. ECTA guidelines set the maximum consumer level in eliquid at 36 mg/ml. The more common highest strength available is 24mg/ml. 

**Nicotine is found in many common vegetables and in plants. Currently, nicotine is extracted from tobacco plant waste, purified and concentrated. It is then used in various applications from pharmaceutical to agricultural. Eliquid should always be made with pharmaceutical grade. 

Diacetyl (Butanedoine) and Aceytl Priopionyl (Pentanedoine) are 2 naturally occuring chemicals found in many foods and drinks. They are also extracted, concentrated and added to some food flavorings. Both taste delicious! They add a buttery, smooth, creamy finish to many things like caramel, toffee, butter, butterscotch, some vanillas, rums, chocolate, even fruit and sweet flavorings. 

While generally regarded as "safe" (G.R.A.S.) for eating, both chemicals present a known risk for inhaling. The more chemical used, the greater the risk.

Medical Science is still "quantifying" the risk. What is known so far: 
    1. Both chemicals are found in cigarettes (approx 200 - 300 ppm's per). 
    2. Both chemicals can lead to respiratory problems when inhaled.
    3. Eliquid CAN (and should) be made without either chemical.
    4. Eliquid made without these chemicals may still contain a "trace" amount (22 ppm's - 100 ppm's),
    5. Trace amounts should not pose a problem and may not be avoidable, as the chemicals are naturally occuring in many foods. 

The electronic cigarette industry has been aware of issues with Diaceytl for several years. Eliquid producers made a point of asking flavoring companies to only provide "diacetyl free" flavorants. 

Unfortunately, there has been a great deal of deception from flavoring companies and carelessness from eliquid producers. 

In 2012 Dr K Farsalinos (Cardiac Surgeon and electronic cigarette researcher) conducted a random test of hundreds of "Diacetyl Free" eliquids from around the world. Diacetyl was found in the majority of them - and at levels that were neither "accidental" nor "contaminate" nor "naturally occuring".

Many companies went "ooops, we didn't know", and proceeded to continue adding Diacetyl, while claiming their flavors were "diacetyl free". Some even ran tests on their mixtures to prove it. They just used a test that was not capable of finding Diacetyl except in very large quantities.

A bit of laboratory hocus pocus?  

Electrovapors, through ECTA, began testing our eliquids at an FDA and Health Canada approved laboratory aware of the issues and willing to look for the smallest trace** levels of Diacetyl, using tests that are the most sensitive to this chemical.

Our point in this: to provide our customers with Diacetyl free eliquid - that is truely Diacetyl free, or contains trace amounts that pose no known concern.  

When any of our eliquid tests positive for Diacetyl or Acetyl Propionyl we won't sell it.
If it's borderline or "trace" (not known to be harmful) we'll let you know and look for a suitable alternative.
We only work with eliquid producers who follow these same guidelines." 

** Trace levels: Diacetyl is found in other chemicals, and even used as an intermediary in creating some. In small trace amounts, we do not know if it is possible to completely avoid - but maintain vigilance and hope that it is. 

Some eliquid producers simply refuse to look for these chemicals. Some believe that lab tests are too expensive. Some don't want to find alternatives for tasty flavors that ring the cash register. 

Some producers are claiming to test, but are not, or are using tests unable to detect Diacetyl / Acetyl Propionyl - except in very high concentrations. 

We believe YOU deserve better. 

In Canada, ECTA (The Electronic Cigarette Trade Association) requires members to test AND provide the results to an independant auditor who double checks everything.  

Electrovapors is a founding member of ECTA. We follow these rules. We purchase eliquids ONLY from producers who also follow these same rules. 

As of June, 2015, we are posting a synopsis of each test for each eliquid. Where the producer has tested, we are providing the synopsis AND a link to the producers site, so you can view complete tests. 

We are new to posting this type of information. It may not be easy to understand. We invite you to ask any questions you have. 


DEG A contaminate in PG Not acceptable in any level in eliquid. Failure requires reformulating
Formaldahyde Naturally occuring & added chemical Accepted for eliquid only as "naturally occuring", in amounts less than what is found in infant vaccinations
PH Balance   For informational Purposes only, gathering data on averages
Nicotine Added optionally Should be exact to +/- 10%. Failures require adjustment. 
Diaceytl May be added by flavorant manufacturers Anything above 22 ppm's (trace) to 100 ppm's is declared with a goal of erradicating. Everything above that is removed, reformulated and retested before being sold again.  
Aceytl Propionyl May be added by Flavorant Manufacturers Same as above (Diacetyl)
