I agree - it bothered me that the rep freedomsmoke (a supplier that i have great respect for) when askede about diacetyl came back with basically its only a little bit and a few flavors - I don't really believe that represents the owners views entirely - and it it does we need to change them. Flavorart is the only major flavoring company that we have heard from that still uses diacetyl - and it IS only a few flavors that we normally make e-juice out of and so it is just a few flavors that vendors that use flavorart flavorings need to substitute with another - I do not see that as asking too much.
Perfumers Apprentice wrote me that within a couple of weeks she will add a section to her website listing ingredients and the manufacturing process they go through. All suppliers should be willing to do this. There are many ingredients that are use in these that caused problems to the lungs. I know SimpleeSims and others were having some problems with Cinnamon flavorings - and after just reading the Wikipedia listing on cinnamon - I wonder if this wonderful flavor quite common ingredient in food should be vaped.
Which is another problem we have - we may know something is safe to eat - but we may not know if it is safe to vape.
Hard to say that was a representative - it was posted under the owner's handle. :\
