To be honest, Katya, I don't know. I did some searches, but couldn't find what it is exactly. Guesses: cinnamic acid esters or salts. They would be less hot than the aldehyde. Maybe there are other cinnamon-like flavors out there too. Linda at TPA will probably know, and she will tell you too. Safety? Haven't a clue. Cinnamaldehyde is a reactive aldehyde. It will etch some plastics.
I have had
countless PMs from people asking me how much cinnamon is safe, what % to use to make a safe juice, what about water-soluble forms, cinnabun flavor, on and on. I generally say I don't know, but I don't vape cinnamon, and here's why, link to wiki, etc. If people want to vape it, fine. Chances are you won't end up in the ER, or worse, but you might, and I have seen some pretty serious posts here from people who have ended up in the ER, with throats closing up. I don't think it should be sold to vape, but its not my call, nor is it illegal. Its not illegal to sue either.
We have 1000s of safe flavors to choose from. I personally cannot even eat much cinnamon, so my interest is helping others vape it is pretty limited. My interest in keeping others from having a vaping-related ER visit is pretty high, however, as it should be for everyone else here. 10% of 1000 people is 100 potential threats to us. The media won't care if it is from a flavor.
Hairball, I don't know what Annette's flavoring is, but an organic extraction of hot cinnamon WILL contain cinnamaldehyde. Has to, organic or not. There are many cinnamons from around the world, some hot, some floral, like Ceylon cinnamon. If it is hot, it has more aldehyde, in general. And a full extract flavoring, which I did not consider before, may contain coumadin.
Kurt, I've read in the DIY forum that using eliquids containing artificial, water-soluble cinnamon flavoring (as opposed to non-water-soluble cinnamon essential oil) is somehow preferable. Do you concur? What is cinnamon artificial flavoring made out of? Does it contain any cinnamaldehyde?
