Professional Black Tattoo Ink or Drawing Ink

Okay, here is my question to all you ink slingers out there! Is there truly a significant difference between lining/tribal ink versus Pelican or Talens or whatever is used (and identified clearly on the bottle) as DRAWING INK? I would imagine, since I used to be a commercial artist in the early 80's, that the chemicals used in drawing ink may pose a hazard in human tissue. I have spoken to a few manufactors of the ink we use in our industry and they explain that the ingredients that go into a bottle of "TATTOO INK" is comprised of ash, glycerin, witch hazel and a few organic ingredients that are non-toxic and non-allergenic. I personally would be afraid to inject a foreign substance (or chemical, al biet) into a customer and be responsible for some kind of reaction that could cost me my license and reputation as a tattoo artist. I take great pride in what I do, worked my ass off getting to where I am today, and consciencious about using anything that I am unfamiliar with into someone just for profit's sake. That said, I would love to hear some feedback on what you, my brothers, use as far as lining and tribal, or just plain black ink for that matter.

pelican is old hat now. some may still used but not many, primarily for lining, same with talons, talons was used for tribal by some but was voided for use for tattooing because it wasnt passed by us agriculture or something like that, im not totally sure (or bothered), eventually came back on market for use as tattoo ink. there are so many manafactures now making ink its untrue. intenze true black is nice to line with, very forgiving if youre starting out. what I mean by that is stuff like kuro is easy to go to deep with, anyway hope that helps?.
