As responsible DIYers, it's our job to do our own research on flavorings for the most part. After all, hardly any of the flavorings we're using are intended for anything except food and beverage. More and more of our vendors are providing MSDS sheets and all pertinent info, but we as consumers are liable for the information that pertains to our purpose of the products. Lorann's is a pretty simple line to define as far as vaping safety. Their oil based flavorings read as such on the labels, i.e. almond
oil, orange
oil, etc. If in doubt, this is a good link to have onhand:

FlavourArt has done the most extensive research of any flavor manufacturer with ClearStream Onward. Not only do they offer a line of products specifically for vaping, but they also offer information on other flavors in their line that are not suitable for vaping and distinguish them as such.
Nicotine River provides SDS sheets on virtually all of their flavorings, Bull City Flavors marks the majority of potentially risky products, as well as a handful of others. We can always go directly to the flavor manufacturer websites and look up any information on their products. But as convenient as it is to have all the info we need from individual flavor vendors, it is ultimately our responsibility as consumers to know the composition of the flavorings before we use them. DIY is the best route to go that actually permits us to
know what we're vaping because no juice vendors out there are going to disclose what flavorings they use or who manufactures their PG, VG, and nicotine. Vendor juice is a crap shoot.
