Flavoring companies CAS TPA (CAPELLA, FA, Flavorah lists Ethyl Butyrate, Ethyl/Amyl Acetate and Benzaldehyde of their safety sheets, because these compounds are also irritants and has to be listed) Some of CAP and Flavorah listings are Trade Secrets. TPA and FA seems to be very transparent, while TPA the most detailed of them all.

Hope this was somehow helpful to those that want to mix for PMMA users, or PMMA users with SQape E[c] or Amerpoint RDtAs.

This lists is not for PC Polycarbonate tanks specifically, which has different entropy thresholds % (break down on Butyric Acid) to compounds than PMMA - and is known to leach - quality PMMA seems to be more flexible to lower %. Both seem to stand up to Acetic Acid and Citric acid in lower %

Reference to PC (Chinese materials used, like in clones, is likely of lesser quality:
