I am still of the same mind as the rest of us here. The product seems harmless and seems to work well. I have burned some myself alongside cotton to try it out and think the cellucotton performs better than cotton. Burned wicks are the issue for me.
What I can't test is any chemical residue so was reading up. There are a lot of scary sounding names used in rayon manufacture. There are also multiple kinds of rayon so it is easy to confuse.
My unscientific testing procedure was burning it, vaping it (so far no burned wicks), and (sorry all) tasting. I put a little ball in my mouth and sucked on it for a few minutes and could not taste any strange residue.
I am vaping it.
You mouth must have been dry after sucking on that CC, surprised it didn't absorb all the moisture in your body.
Thanks for the insight, pretty much how I feel. The fibers smell clean and absolutely disintegrate with an open flame, no off colors or smells there, either. I suppose without some expensive lab work or something we can't truly know, but what I do know is I vaped with silica for a long while and simply cannot go back after using cotton. Silica just tastes wrong anymore.
