Much is being said about the “healthiness” of the portable vaporizer. Although, given their youth, no relevant statistical data yet exist, most of the consulted entities have issued a favorable opinion. In short, the most frequent conclusions that we can find, basically come to say that while it can not yet be shown that it is effective to quit smoking, what is fully proven is that it is not harmful to health.
Of course, as it could not be otherwise, the portable vaporizer already has its modest community of detractors. These, to try to defend the indefensible, the insalubrity of the portable vaporizer, rely on the presence of Propylen Glycol in the cartridges, which has become the trigger of controversy.
Propylen Glycol is an organic, tasteless, odorless, odorless, oily texture obtained by the hydration of propylene oxide.
In the cartridges of our portable vaporizer, the presence of this organic compound has a double functionality: On the one hand, given its low freezing point, it acts as an antifreeze, keeping the humidity of the cartridge sponge that must be in contact with the atomizer; and on the other hand, it is the compound that makes possible the production of the vapor with the density sufficient to resemble the smoke of the traditional cigarette.
This compound, when passed to our body, is metabolized to lactic acid, just as normally occurs in exercised muscles, and is a normal part of the glucose metabolism process, easily converted into energy.
Its toxicity is very low, it requires the intake of large amounts in a short period of time so that it can eventually cause harm to human health. The few cases of known serious toxicity are related to inappropriate intravenous use or accidental ingestion of large quantities by children.
Obviously, as it can not be otherwise, any abuse of any existing compound in nature, even the purest water we can find, can be harmful to our health (if we drink more than 7.5 liters of water in a short space of time, we will be in a critical situation).
The Food and Drug Administration (FDA) has determined that Propylen Glycol is “generally considered safe” (GRAS) for use in food, cosmetics and medicines.
This compound has many applications. Some of them:
In medicines, such as diazepam.
As a moisturizer in pharmaceuticals, cosmetics and food.
As solvent for coloring and flavor enhancer in food (labeled as E1520).
Like antifreeze in food.
In the machines of artificial smoke that are used in the spectacles.
In many cosmetic products, even for babies, such as bath foam and shampoos.
In moisturizing creams, cosmetics, toothpaste and mouth rinses.
As an ingredient in massage oils.
As support in fragrance oils.
As a cooling agent for beer.
In short, Propylen Glycol, in the right doses, is completely safe. If the portable vaporizer had to be withdrawn from the market due to the presence of this compound, for the same reason thousands of cosmetics, pharmaceuticals and food products would have to be removed.
