About 14 years ago I was working on an implantable vascular embolization 510(k) device that was based on an acrylonitrile polymer that utilized acrylamide as a starting monomer. We attempted to use exhaustive <g class="gr_ gr_22 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace" id="22" data-gr-id="22">extractables</g> testing to demonstrate acceptable risk. The residual <g class="gr_ gr_55 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace" id="55" data-gr-id="55">acyrlamide</g> monomer amount was less than 20 parts per billion, 20 nanograms per gram, which was our testing detection limit. FDA rejected our risk assessment, and forced our hand to perform a carcinogenicity study and we ultimately achieved clearance after passing a 6-month transgenic mouse study.
(Our argument that acrylamide can be found in potato chips and french fries was not submitted)
I have attached an old compilation of acrylonitrile info that I prepared at that time - 2004.
This does not answer your question directly, but I hope it helps.

Hi everyone, we are developing a lubricant for joint problems, because It contains polyacrylamide gel, we need to monitor the acrylamide monomers residue. Can anyone tell me the acrylamide monomers benchmark in different countries (USA<g class="gr_ gr_27 gr-alert gr_gramm gr_inline_cards gr_run_anim Style replaceWithoutSep" id="27" data-gr-id="27">,Canada</g>, China, EU......)?
Any input is appreciated
Thanks in advance
