Let’s talk about Five Pawns and their liquid that was tested and measured up to 2,500 ppm of acetyl propionyl (see lab results below).
Since Cloud9 removed the diacetyl and acetyl propionyl lab test results from their website after receiving a C&D from Five Pawns, I uploaded all the test results to scribd and imgur:
Dr. Anne Hubbs talks about her studies on lung disease caused by diacetyl and acetyl propionyl:
Utilizing this quantitative risk analysis, NIOSH recommends that exposure to diacetyl be kept below a concentration of 5 parts per billion (ppb) as a time-weighted average (TWA) during a
40-hour work week. NIOSH has determined that workers exposed to diacetyl at this concentration should have no more than a 1 in 1000 chance of suffering reduced lung function associated with diacetyl ex
