Thanks for the links, made my search much easier. I'll try not to get too carried away on this one (my last post was originally going to be like 2 sentences) as I have some homework to finish up still.
This list was supplied by Ludo of jantyshop (major thanks for sharing btw), he says all ingredients (nicotine is not on the list, this is just the base that they use) are safe and legal and that their liquids are approved by the University of Naples and the Italian Ministry of Health.
On a quick personal note I find it unlikely that he sent a bottle of prepared eliquid and explained that it was to be repeatedly vaporized and inhaled over long periods of time and they approved, more likely they were sent a list of ingredients (not including nicotine of course) and they said none of them are controlled or considered a safety hazard (or perhaps he just checked to make sure none of them are banned), but who knows and in any case it is irrelevant.
All information was found on chemical supplies websites, which are required to have the safety and first aid information (MSDS) of any chemical they sell, will gladly send links if anyone wants em, but I don't know if I'm allowed to post links yet and don't wanna risk having to re-type.
The list:
menthol -
3-methylcyclopentan-1
2-dione
1-malic acid
2,3,5,6-tetramethylpyrazine
2,3,5-trimethylpyrazine
beta-damescenone
acetylpyrazine
2-acetylpyridine
ethanol
I assumed this would just be the usual "may cause liver damage, blackouts, unexpected pregnancies, and barfights" warning, but there was specific data on other methods, I'll leave out the consumption part.
[FONT=Verdana, Arial, Times New Roman]
[FONT=Verdana, Arial, Times New Roman][FONT=Verdana, Arial, Times New Roman]Eye: Causes severe eye irritation. May cause painful sensitization to light {haha ever had a hangover where bright lights hurt your eyes?}. May cause chemical conjunctivitis and corneal damage.
Skin: Causes moderate skin irritation. May cause cyanosis of the extremities. [/FONT][/FONT][/FONT]
[FONT=Verdana, Arial, Times New Roman]
[FONT=Verdana, Arial, Times New Roman][FONT=Verdana, Arial, Times New Roman]Inhalation: Inhalation of high concentrations may cause central nervous system effects characterized by nausea, headache, dizziness, unconsciousness and coma. Causes respiratory tract irritation. May cause narcotic effects in high concentration. Vapors may cause dizziness or suffocation. [/FONT][/FONT][/FONT]
(don't know if we are causing it to decompose, more than likely it is not much if at all, but a rapidly heated coil could ignite small amounts of the vapors)
Hazardous Decomposition Products: Carbon monoxide, irritating and toxic fumes and gases, carbon dioxide.
rhodinol
Other Toxic Effects on Humans: Hazardous in case of skin contact (
irritant {another one oh my}), of ingestion, of
inhalation {doesn't give details other than irritant here, guess they didn't expect people to be breathing it often}. Slightly hazardous in case of skin contact (permeator).
Toxicity of the Products of Biodegradation{note this isn't the same as decomposition, this breakdown will happen naturally given time}:The products of degradation are more toxic {can't wait!}.
vanillin
This one I red flagged on instinct, had some irritation problems with similar substances before, so I checked it first.
Other Toxic Effects on Humans:
Hazardous in case of ingestion, of
inhalation. Slightly hazardous in case of
skin contact (irritant, permeator {this could of course cause a rash, and skin irritants are usually the major factor in acne outbreaks of people that aren't in puberty}).
May affect genetic material (mutagenic). {yea mutagenic things are the cancer-causing stuff, wouldn't that be such an ironic ..... slap if we all got cancer within a few years}
May cause adverse reproductive effects based on animal test data.
Special Remarks on other Toxic Effects on Humans:
Acute Potential Health Effects: It may cause eye,
skin, respiratory tract, and mucous membrane irritation{oh snaps plx}. It may be absorbed by the skin. Ingestion may cause gastrointestinal tract irritation and affect the cardiovascular system, respiration, liver (jaundice), urinary system, behavior/nervous system (
muscle weakness {how many reports of muscle soreness have we had? weak or reduced binding of muscle fibers can cause normal exertion to over-exert the muscle, thus soreness}, somnolence, coma).
Chronic Potential Health Effects:
Inhalation: Prolonged or repeated inhalation may affect the brain and blood (changes in white and red blood cell count). {for the record chronic inhalation is what we are doing}
Ingestion: Prolonged or repeated ingestion may affect the urinary system, liver, heart, and metabolism (weight loss).
The following may or may not apply, I'm not sure if any is heated to the point of decomposition and no decompsition temp is listed.
Hazardous Decomposition Products: Carbon monoxide, irritating and toxic fumes and gases(
When heated to decomposition it emits acrid smoke and irritating fumes.-found this on another msds too), carbon dioxide.
propylene glycol
Wow, I was really praying for this one too, sorry guys, at least it isn't too bad.
Slightly hazardous in case of skin contact (sensitizer). {making skin a little more sensitive to other irritants could contribute to the acne}
Chronic Effects on Humans: May cause damage to the following organs: central nervous system (CNS). {oh joy}
Other Toxic Effects on Humans: Hazardous in case of ingestion. Slightly hazardous in case of skin contact (irritant{I believe this makes 4 skin irritants so far}, permeator), of inhalation.
Flammability of the Product: May be combustible at high temperature.{lol, e-cig go boom!}
Special Remarks on Fire Hazards: When heated to decomposition it emits acrid smoke and irritating fumes
Ok this ended up taking 10 times longer than I thought, I will have to stop here, I will check the other chemicals out tomorrow or something.
So far I have to say I hope this isn't the same formula everyone uses. The vanillin in particular seems easily omittable, it can't be there for anything more than a subtle flavor and it simply isn't something we should be inhaling, especially on a daily basis.
Maybe we should start asking suppliers to provide a list of the ingredients in their eliquids (after all, if we are going to be using these daily, shouldn't we strive for the safest possible formula?) , and I will see if I can find some more info on long term effects of pg, vg, and the other essential ingredients. I know we have all been hoping the FDA won't shut us down, but that also means that lawsuit-fearing companies havent had scientists check it for long-term safety, so we should do our best to make it as safe as we can (I believe that most of us switched to e-smoking for a safer lifestyle). This board has the potential to make this happen due to the direct communication with our suppliers and group thinking/process improvements/feedback that it allows. As for any supplier not wishing to release their ingredient list for fear of people copying it, everyone here is capable of making their own juice, we come to you because it is pre-made and inexpensive (though personally I plan on making my own unless I find a pre-made liquid with ingredients that are as safe as what I could make on my own), people who want to make their own already are, the different flavors are just for novelty.
Blah no sleep for me tonight
hope someone finds this info slightly useful, and any contributions on ejuice formulas (from suppliers or home recipies) would be nice so we can share ideas and discuss possible improvements in one area (I don't feel like combing through the home bake formulas and testing it all myself, and there are plenty of people already knowledgeable in the area of how different ingredients affect the end product).
I'm out. <puff>
