How do I best prepare next lotion? Erythromycin 4 G Zinc acetate 1 G acetic acid 2 dr Disinfectant alcohol 65 g propylene glycol 10 g water AD 100 g

If we compare the formula of the NF VI page 1269 Then it is striking that there is a certain amount of water. I fear that this cannot and that the solution should not contain water. Personally, I would also replace the acetic acid with ammonium acetate solution 3g.
