Propylene Glycol

[jamie]

Well, drive under a streetlight at night...it doesn't bother me during the day. At night, when lights hit the windshield, you can see it--it is like smeared fog on the inside and comes off with your finger.

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

And thanks to everyone who provided info, all the bits help.

booboo,

Just a shot in the dark here, but you may want to check your anti-freeze level.
Sometimes the vehicle's heater core will develop a pin hole leak and this will cause exactly what you are experiencing. I've replaced 3 of these in my truck over a 17 year period. You can also check the passenger side floor for dampness/moisture.

Just a thought.

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.

My biggest concern is the thick film it's put on my truck windows. Yes, analogs put a yellow thin glaze on the windows, but it could build up for a long time before you absolutely couldnt see. However, with pg vapor in the vehicle, it wasn't even a week before the window was so coated, you couldn't see a thing to drive-- and it is a thick, white coat. Don't get me wrong, I love my e-cig, but that did scare me a bit wondering how that film was coating my lungs.

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:

Curious. I cleaned the windows in the front room of my house (my main vaping room) a week before Christmas. By Christmas day they had a coating on them like a fine greasy condensation. Anything to do with vapeing,perhaps? Anyone else noticed anything similar?

Vapey Windows....

Thanks Kate ! for the link , you know how newbies are LOL
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 =)
