Bill, i don't think the companies you mentioned are major players in the flavoring industry as a whole. I have a friend who has been doing research on major companies in that industry as part of his job, and he hadn't even heard the name of most of the companies you have mentioned.
I did a quick search, and these were the biggest companies in this industry between the years 2009 and 2013 :
Flavor & Fragrance Industry - Top 10
Now i don't know if any of these companies would even sell at the quantities liquid vendors purchase, but just because we haven't heard of food flavoring and fragrance companies that don't cater to the diy community, doesn't necessarily mean they are arcane.
Point taken. Still, the companies on the list you linked are arcane to me, and I think they might be to most vapers who aren't personally involved in the industrial level of Agri-Business.
Heck, I couldn't tell you who the major auto parts producers are or drywall manufacturers, either, because I don't live in those worlds. Most of the commercial/industrial activity on this planet is invisible to me personally and quite mysterious from my standpoint as an individual. That's part of why I asked my question in the first place, so thanks for doing some research.
