Thanks for the detail. You're right, I have it too and stand corrected.

Yes I've had antifreeze coming through the vents before that did something similar--in fact I was going to use that to describe this. Difference is you can smell it and it doesn't coat all the windows to the back crew cab. And you also make a good point, since it is the ethylene or propylene glycol in the antifreeze that causes this effect on the windshield. I use ethylene myself, but as I've read:
"Ethylene glycol and propylene glycol have similar physical properties and uses. Their chemical structures differ by only one methyl group (ethylene glycol, HOCH2CH2OH;propylene glycol, CH3CH[OH]CH2OH)."
Which to me means that whether it is the cig or an antifreeze leak causing film on the windows, it is still from the same thing: _____glycol.
Wasn't trying to start an argument here, just had a concern I wanted to share since we are all in this together.
Ya know, I REALLY hate to say this, but now that you say it I realize what bothers me about the smell of the vapor... it REMINDS me of car anti-freeze. I've been trying to pinpoint it the last two days (just started e-smoking on Tuesday) and your post here didn't immediately register with me until I was driving in my car a little while ago. Then it dawned on me... "that's IT!"... not a particularly nice revelation.
I grew up around car mechanics and machine shops, so this smell is not foreign to me. It's not a strong bad smell with the e-cig, but it is definitely reminiscent of car anti-freeze on a cold morning when your automobile has a head-gasket leak.
I was a little disturbed at the "film" you say is on your car. I've got another thread going on in another e-smoking forum about my "paranoia" with inhaling this PG stuff. I also seem to be suffering a bit of a soar throat the last couple of hours today and I'm hoping it's not because I have some PG sensitivity (I'm one of those people who is allergic or "sensitive" to a lot of things). All I can say is for myself I don't plan on e-smoking to become a way of life... I hope it's only a stepping stone to getting off all smoking for good.
Good thing is I'm WAY WAY down on tobacco smoking! Almost 2 packs a day normally... since I started the e-butts I seem to have averaged around 6 analogs per day so far.
I'm not sure i like these bits............
Boiling Point:
188.2C (370F)
Hazardous Decomposition Products:
Carbon dioxide and carbon monoxide may form when heated to decomposition. Aldehydes or lactic, pyruvic or acetic acids may also be formed.
Conditions to Avoid:
Heat, flames, ignition sources and incompatibles.

I agree, those pieces of information made me uneasy too. But our atomizers are not getting anywhere near 370 degrees F. I imagine that decomposition does not happen until much past boiling point. So I don't think it is something to worry about. Mind you I am not a chemist by any means. So I could be completely wrong.
I guess it's not Ruyan? I thought they made the DSE901's for some reason, and was corrected. So it is the cartridges for them, whoever makes them, that I am using.
Hummm Yes quite a disturbing find there ! I have been smoking the e-cig for only 2 days so i can't really make any comments but will be following this thread closely ............
I knew the residue on windows had been mentioned before:

Thanks Kate ! for the link , you know how newbies areLOL
Hum this is a quite interesting thread , hopefully this is not a health Hazard , i know someone is gonna tell me real cigarettes are no good but that i know , just wondering about that issue .
Well, my personal opinion is that PG deposit a sediment in your lungs. I can feel it in my nose. I wonder if the moisturizing effect of the PG can indeed help your body in softening the tar and all the other junk that long time smokers have accumulated in all the years on analogs, but i don't think it can be defined as safe and healthy. One thing is for sure: the human body can deal with PG much better than with tar, and the vast majority of vapers reports an improvement in health and lung capacity after changing their habit from analogs to e-cig. Still, we're the guinea-pigs of vaping, and must accept the risk involved.
Just my personal thoughts =)

Chapstick,hand-cream,face lotion, and even some pre-packaged foods have it on the ingredient label.
If PG hasn`t killed us already from skin absorption or eating it, then I highly doubt smoking it is gonna do us in.

Difference between windows and lungs (or any skin tissue): lungs aren't made of glass. They are 'passable' - and that's exactly what PG does... and as soon as that has happened (and/or while that is happening) the PG is being broken down - into lactid acid. Something that our body is used to and can handle / disperse of.
I don't see any reason to be worried about PG in my body myself.

somewhere on here (i forget the title of the thread) there's a thread with post about research showing that is a natural antimicrobial that kills viruses and bacteria. In it is mentioned a study that showed that it might even protect a person from catching influenza.

I didn't read through the entire thread...too tired...but thanks for the info.
Also states no harm from inhalation...are we inhaling it or ingesting it? I think its a combination of both lol

Yep, maybe i'm just a little paranoic because all of this seems too good to be true =) Nice point with the "passable" stuff, PG does that all the time with skin care products. The sediment i was talking about shouldn't be permanent at all, just wanted to clarify that since my previous post was ambigous on this point. Worst case scenario, some of it sticks to the mucus (EEK! Gross! =P) and can later be expelled by coughing/sneezing. Hopefully with that softened tar =D
Sorry, seems like i cannot yet edit my posts or i am just blindfolded =)
Well, i was long into my post, when i decided i needed further research, and i found this:
"This is because lactate itself is not capable of releasing a proton, and secondly, the acidic form of lactate, lactic acid, cannot be formed under normal circumstances in human tissues. Analysis of the glycolytic pathway in humans indicates that there are not enough hydrogen ions present in the glycolytic intermediates to produce lactic or any other acid."
Source is the allmighty wikipedia: http //en wikipedia org/wiki/Lactic_acid
Until now, i was sure that the lactic acid was the by-product of an anaerobic reaction to feed energy to the muscles, but it looks like i was wrong. Katink, can you point out where have you found that PG transforms into lactic acid once it gets into our body? From what i can understand, it's unlikely that this acid will form into our body, and if you are proven right then it's not something that our body is used to handle.
I'm not tryng to be a smart@ss pal, and by far i am not a scientist. I will try and look for more infos in the meanwhile =)

I thought lungs are more like sponges than passable...if it sticks to anything, it would coat them also. As for the lactid acid thing everone is talking about as being normal, having excess lactic acid in your body is a serious problem that results from lack of oxygen. Look up metabolic acidosis or lactic acidosis.
"Although the toxicity of propylene glycol is low, if excessively large amounts are absorbed, the following health effects may be seen:
an elevated osmolal gap,
severe metabolic acidosis (caused by the metabolism of propylene glycol to lactic acid), and
coma, seizures, and hypoglycemia (rarely, among patients who ingested large amounts of propylene glycol over several days). "
Well, I look at it this way, I can't be getting much more than 2ml of propylene glycol per day, not taking the exhaled stuff into account. That's well below toxic levels as far as I know.
Dr Loi who has been doing clinical studies in Malaysia suggested that the pg might be good for helping us to clear our lungs out, it could act as a cleaner and help us cough up the old tar and other smoking residue.
