Etchall Cream is Ammonium Biflouride at 20% solution.
Etchall Liquid is Ammonium Biflouride at 27% solution.
You should use gloves and avoid the eyes with these but they are much safer than what was mentioned in the Monash university article. i hope to god no one is using that kind of acid for etching and especially not at that concentration. The chemical in the Monash University article was Hydroflouric Acid at a 70% lab solution so much more pure.
I can't get into the first link.
