I just recieved my Lorrans bakery emulsions. After a little real world testing and careful reading of the chemical properties,uses and warning on Xantham gum I have decided it is probably NOT safe to vape. This is just my opinion...but here is the MSDS:

Of particular concern to me would be it's ability to DE-regulate blood sugar levels making it potentially very dangerous for diabetics.
and this:
"the hygroscopic property of xantham gum can impede normal breathing" Now granted...the MSDS is refering to the dust but why take a chance?
But OMG...does it taste and smell wonderfull!! I am hoping maybe someone else knows a little more about it and can add something to this topic.
Also of note is the fact that being so heat stable it will probably wreck atty's. The extremely small percentages used in foods and liquids is misleading and should not be mistaken for "safety".
sorry

I really had high hopes for this stuff...but hey....I can sure use it to bake with!!!
