Could you pls compare for me the following formulas and let me know all your comments about it?
NH4HF2+HCl+CAPB (C19H38N2O2) and
C2H4O3+HCl+CAPB
what`s the most dangerous one? what`s the most corrosive? which one of them is more indicated for etching a natural surface or a tile?

Coco amido propyl betaine? And C2H4O3 is what, acetic acid 2-ol? What are those supposed to do?
The one with the acidic fluoride is of course the most corrosive and poisonous...

C2H4O3 is glycolic acid, CAPB yr right! It is a solution and I would like to know if by substituting NH4HF2 with glycolic acid I would get the same
result...how much should I add in %age to get same solution in strenght?
