Formaldehyde in Juice?

[skoony]

I have checked with my coils - at 12 W (during dry burn, i.e. no wick, no liquid) coils have temperature about 1800F, close to melting point of iron. When vaping coils are cooled with boiling juice delivered through wick to temperature somewhere in between of boiling tempearture PG and VG, i.e. between 370 and 554 F. Dry hit means there is not enough liquid to cool coils and temperature may jump much higher than safe level and burn remnants of juice and wicks, providing not only unpleasant experience but some unpleasant stuff also. Fortunately after dry hit nobody will continue to vape at the same conditions, so amount of produced bad stuff is minuscule and not dangerous.

1800F ? that is incredibly hot.
that would melt a ce5. the metal of your atomizer case would glow red.
even the best regulated mods only will do maybe 600F. that's the internal
heat of the coil.its not recommended to go over 450F.
most of this heat is converted to work. vaperizing the water.
the liquid itself would dampen some heat.
a dry hit means there is insufficient water vapor to atomize the base mix
which will thicken and burn.
you do not boil the PG or VG. you would burn your lungs out if it got
that far.

you are again about non-existent water...

its the water that makes the whole thing work.

As I understand it, formaldehyde is a product of combustion. The point being that if somethings burning, you will know it.
Seeing as the OP didn't include any actual data or links to any studies I assume it's just detritus from scare mongering from the study done last year which surfaced in January. The insinuation of this "testing" was that CH2O is a hidden component of e-juice silently poisoning you. This is not the case.

If something is genuinely dangerous about vaping, I and I assume ECF members want to know about it. Not the "I heard that vaping is bad for you" variety.

Suck my mod debunked this thoroughly. He swears all through the video like a drunken sailor, so I have broken the link. Hopefully this is within the remits of ECFs rules on such things.

Umm how hot does the burner on your cook stove get? Does it melt down your home? Same thing it is about the pinpoint amount of heat on the coils, they do not heat up the entire atomizer to that temp, well unless you have a battery meltdown then it might get that hot but not from the coil. Your hairdryer coil gets extremely hot but does the entire hair dryer?

I am sorry, but everything is wrong in you post. It looks like I should start a special thread about vapor production.

And heat generation and propagation too.

your standard stove top reaches higher temps.
it is also using way more energy than the batteries we use.
at 1800F your whole set up would become un-usable.

It is all about the mass, All about the Mass, and the wattage, No meltdown... Hmm a tune there. Yep it is high school physics pure and simple. If the coil was surface bonded to the tank housing all along it's length it would not get hot until your battery was almost dead from the drain get the picture? It would never get up to 1800 degrees. It is all about the mass easy to heat a few micrograms of coil up but to heat that the tank body takes much more BTU's. Why a coil on a dry wick will glow like heck but a coil on a wet wick is heat sinked and the vaproization also cools it.

Melting temperature of kanthal is about 2200 F. No problem with melting kanthal with a mod. Easily.

 

[Robert Cromwell]

Not sure about exactly 1800 degrees but you might want to check this out.

Bright orange is 1700 deg f or there abouts.

It appears that more and more studies are finding formaldehyde being released in ejuice when the voltage is 5 volts or higher. Anything lower than 5 volts and no trace of formaldehyde is being detected. Also, the formaldehyde detected is 15X stronger than that found in a normal cigarette.

Since formaldehyde is a carninogen, what does that mean for us vapers if we are chain vaping on sub-ohm devices and etc everyday? That's a lot of formaldehyde we are taking in each day...

I'm kind of scared at this point for my health...

Will we be seeing formaldehyde-free juice once the FDA steps in? How would that even work?

I'm just going to

be honest. I've put some crazy stuff in my body in my youth. I don't think E Juice is one though. At this point I love my two main ADV juices so much I don't care what is in them. If at any point any of you all get afraid of any juices (especially custards) just shoot me a message and I'll reply with my mailing address. Sho Nuff

As a tootle puffer I am not concerned about formaldehyde at all.

typed as I tootle away at about 8 watts.

Back to the op's topic, the inhalation of diketones like diacetyl that is produced from certain flavorings is where the real discussion is at. There needs to be more research along that avenue.

These studies are so blatantly biased its not funny, you get more formaldehyde and arsenic exposure touching a piece of pressure treated lumber at home depot



Mmm mmm call it 3c -cajun clearo coils

Hey ! I've been slinging PT lumber for 20 years Still kicking and in pretty good health.

Exactly. Also you can check this: Know Temperature when metal glows red | Hearth.com Forums Home

When I dry burn a coil I usually go to 1600-1800 F (good to get rid of contamination, no additional cleaning needed). And it can easily can be done (for my 1.2-1.6 coils) at 8-10 W.
