bioflame has 'acetate' in it also, it tastes bitter if you touch it with your finger and lick your finger after you make anything with it, no matter how long you let it evap.. bittering agent, so people don't drink it? maybe..
it also.. may or may not have the binding agent from the usual isopropyl also that binds it to water without separation.. but might just have isopropyl prior to water added, then maybe doesn't have the binding agent AND acetate or does.. unsure at this time.. i'll have to ask the company that makes it directly on these questions.. acetate is not toxic on small amounts i've been reading on datasheets, etc.. BUT it works great, makes great stuff.. similar to isopropyl, but possibly with a trade off of binding agent for acetate.. no sure.. i recommend smoking things made from it, but maybe not eating it.. there may be a situation where acetate is accumulating and adding up.. BUT it says burns clean etc, but that just means without a sooty residue in the chimney.. etc.. use at own risk.. using it as a clean up chemical it leaves behind a white foggyness that isopropyl and everclear don't.. so at this time.. i give it a 9/10 or a 0/10 cause it might be bad to use! (shrug).. no bad effects noticed as of yet.. used about 10grams or more of shatter made from it already over the past 6 months.. personally i find it takes different terps out of the bud possibly, and tastes far more terpy than using butane or isopropyl.. i recommend freezing it and bud.. 250ml > 7g.. and putting both in a pot, agitate it with one hand and watch the liquid turn from clear to yellow to green, stop before green, pour through coffee filter, evap at 80degrees on reptile mat, infront of a fan on medium setting.. check 6hrs later, should be close to done, and if dry to the touch like stained glass, then scrape and put on parchment on top the reptile mat at 80degrees again until it turns into a clear glass sheet, put a tool in the freezer, then take it out and mold the shatter to whatever form you want, as it gets too sticky to touch, put tool back in freezer and repeat, and put shatter in fridge for 30 seconds, then take both back out and continue shaping it, if you make it thin enough it will be clear, and perfect looking if all the same thickness.. your welcome everyone.. gluck..
