JX, you want the Flavor Extracts
faerie's finest - extracts and liquid flavors
If you then click on a flavor, the ingredients will be listed at the top under the flavor name.
I think that "extracts" is an over-loaded term and one with inconsistent usage. Extraction is one method of getting flavor from something, it really has little to do with the storage of that flavor AFAIK.
Then again, there are US laws concerning certain terms like "vanilla extract" versus "vanilla flavor." The former is quite specific: "The U.S. Food and Drug Administration requires that the solution contain a minimum of 35% alcohol and 13.35 ounces of vanilla bean per gallon." The latter is not so specific and is open to different strengths, solution preservative, and other ingredients. So maybe certain other flavoring have similar, specific definitions? I'm not sure.
Alcohol is not considered dangerous to atomizers, but may overwhelm one with bitterness. Oils are often considered to be a cause of gunking up atomizers, but there are plenty of people who use them in their flavors. With a strong oil-based flavor, the amount of oil in a finished ejuice is minimal. Much/most of this oil gets vaporized, but possibly not all, and blowing out the atomizer and/or flushing with Everclear/vodka should clear almost all of it.
