propylene glycol, and glycerine...... see this, if you havent already.

[V4Lis4me]

So, I am aware that many of you may have seen this already.... I am also aware that many have not. Either way, there will be some discussion within this post... I am sure of that!
The links that follow are the MSDS (material safety data sheets) sheets for propylene glycol and glycerine. Whether they are GRAS (generally recognized as safe) or not, these are detailed safety standards for the materials at hand. All of us in here come into mass exposures of these materials through vaping.
I know that this post will lead to some heated discussions, but the links are pure facts. Make an informed descion from there.



propylene glycol....
http://www.sciencelab.com/xMSDS-Prop...glycol-9927239
*note section 3, page 1.....substance may be toxic to central nervous system (CNS).
Repeated or prolonged exposure to the substance can produce target organs damage.
*note section 11, page 4..... may cause damage to the following organs: central nervous system
*note top of page 5... specifically ingestion, inhalation, and CHRONIC EXPOSURE....
Ingestion: It may cause gastrointestinal tract irritation. It may affect behavior/central nervous system(CNS
depression, general anesthetic, convulsions, seizures, somnolence, stupor, muscle contraction or spasticity,
coma), brain (changes in surface EEG), metabolism, blood (intravascular hemolysis, white blood cells - decreased
neutrophil function), respiration (respiratory stimulation, chronic pulmonary edema, cyanosis), cardiovascular
system(hypotension, bradycardia, arrhythmias, cardiac arrest), endocrine system (hypoglycemia), urinary system
(kidneys), and liver.
Chronic Potential Health Effects:
Skin: Prolonged or repeated skin contact may cause allergic contact dermatitis.
Ingestion: Prolonged or repeated ingestion may cause hyperglycemia and may affect behavior/CNS (symptoms
similar to that of acute ingestion).
Inhalation: Prolonged or repeated inhalation may affect behavior/CNS (with symptoms similar to ingestion), and
spleen
glycerine.....

*note section 3, page 1..... The substance may be toxic to kidneys.
Repeated or prolonged exposure to the substance can produce target organs damage.
*note section 11, page 5..... Chronic Effects on Humans: May cause damage to the following organs: kidneys.
*note section 11, page 5..... Chronic Potential Health Effects:
Ingestion: Prolonged or repeated ingestion may affect the blood(hemolysis, changes in white blood cell count),
endocrine system (changes in adrenal weight), respiratory system, and may cause kidney injury.



Well, there it is......
Please, as I vape all the time, I welcome any thoughts on this.....
It has to be shown.

I was looking in the cupboard the other day for stuff with propylene glycol in it and one thing I found was McCormick flavoring. So for one all the people who have eaten flavored cookies, cakes, and candy have been poisoned with the stuff. Its the same with petroleum products, gas, oil etc. but the plastic containers your food is stored in are also made from petroleum products. Same kind of deal. However I try to use vg anyway.

If you chackout an MSDS on vegatable glycerin such as Cargil you will get a different read than the above

[pbtaylor]

I can understand where your coming with this. This is something that should be looked at in long term use.
As well look at all the things that we take in everyday that have the same thing in it.
I am sorry but I am not too worried. I like a cookie or 2 a day. they have it in ice cream cones.
So if it bothers you I am going to suggest ya use something else.

those are very small quantities....
vaping entails a direct consumption of the pure product.

from the info i have come across, glycerin.... no matter what its source is vegetable or other, is still the same end product. Some people just believe that the vegetable origin is "more healthy"

if anyone has other info, please inform me.

I've read these many, many times.

factoid: They use propylene glycol in asthma inhalers. People who have sensitive lungs use those inhalers. If it was so bad to inhale, wouldn't there have been massive recalls of those inhalers?

"PG has been used as the aqueous-based chemical additive in asthma inhalers and nebulizers since the 1950s, with no serious side effects known. PG, because of its water-retaining properties, is the compound of choice for delivering atomized medication. It is also a common diluent for injectable medications, constituting 40 percent of the intravenous form of Phenytoin, an anti-seizure drug." http://www.ehow.com/about_5499611_da...ne-glycol.html

MSDS Sheets are usually worst case scenarios, with excessive exposure or people with certain conditions that make them higher risk. They are CYA for companies - same as those disclaimers on drug commercials. They have to list every known reaction that anyone ever had as a possible risk, even if it wouldn't even affect 99% of the people.

Health Canada cited PG simply as a "known irritant" in it's attempt to scare people. Sure, it's on the MSDS as a possible irritant - to people who have never smoked a pack a day of toxic tobacco. We were sucking in ammonia and arsenic. I highly doubt it'd be an irritant to most former smokers! lol

[yovapavapa]

what about people with asthma then ? are they doing all that damage ? the reason i ask is because PG is in asthma inhalers . if it is damaging to them , then what does that say about our beloved FDA ?

[Sun Vaporer]

Kristin just about explained it all when she correctly cites the use of PG as the vehical in Asthma Inhalers as well as NRT"s such as Nicotrol all having spent millions of dollars on studies and obtaining FDA approval.

So if you are looking for the ultimate stamp of approval---PG has it by the FDA.
