E-liquid Additives

E-liquid Additives

As the Vapour Products industry evolves, businesses get more creative in an effort to remain at the highest competitive levels. For e-liquid manufacturers, that involves manipulation of product recipes in an effort to set them apart from the rest of the players.

The ECTA supports this competitiveness and creativity, however there are limits on what can and cannot be done to the product that would limit our support.  Obviously, weights and measurements are the variable.

What’s in the e-liquid?

That is one of the more common arguments that opponents to our industry use to discredit or impose scrutiny on our industry.  For that reason, the ECTA has produced a list of what is expected to be in the e-liquid as well as items that should not be used.  Our general philosophy for manufacturers is that if something does not need to be in the e-liquid, it should not be used in the e-liquids.

What can be used in e-liquid?

These are the compounds that should be used to manufacture e-liquid. These were selected because they have a very long history of studies or generally safe use for inhalation or oral ingestion:

  • Propylene Glycol (USP grade)
  • Vegetable Glycerin (USP grade)
  • Glycerol (USP grade)
  • Alcohol  (< 2%, Human consumable and pure as possible)
  • Water (Distilled or Deionized)
  • Flavourings (Food grade)
  • Nicotine (< 3.6%, USP grade)

There has been some evidence that PDO (1,3-Propanediol) “may” be a viable substitute for Propylene Glycol but there has not been enough research for us to be able to recommend it as an ingredient for use in e-liquid.

Similarly, sweeteners such as Sucralose is not on the list above. Although there appears to be no strong evidence to indicate that it should not be used, there is significant skepticism within the scientific community. For that reason, if it is used, use as little as possible and it should be included on the Ingredients list.

NOTE: Ingredients should be listed in descending order of concentration, down to 1%. Some ingredients, such as Ethyl Alcohol have regulatory requirements to be listed even when the concentration is less than 1%. Additional details can be found in the Food and Drug Regulations.

What should not be used as an additive in e-liquid?

There are a number of different compounds and chemicals that should not be used as an additive in e-liquid for various reasons.

  • Diacetyl (2,3-Butanedione)
  • Acetyl Propionyl (2,3-Pentanedione)
  • Illegal or controlled substances
  • Analogs, isomers, salts and derivitives of any scheduled/controlled substance
  • Vitamins or Dietary supplements
  • Prescription or therapeutic medicines
  • Caffeine or other oral stimulant
  • Artificial Food Coloring

As the industry evolves and more information comes available, these lists may be changed.
