Hey everyone. I'm new to the forums.
I've read a few posts on here that I found using Google. I'm a little concerned about the safety of using Betadine as an iodine solution for sanitizing equipment, ie. bottles, siphons.
The label says that the only active ingredient is Povidone-iodine, but there are two other ingredients that bother me.
1. Pareth 25-9. I'm not sure what this one is, but I've read that it is not food-safe. It is also listed in the TSCA (reference
2. Sodium hydroxide. OK, this one is obviously bad.
I'm not sure the concentrations of these two chemicals, and the solution is incredibly diluted (1% iodine to ~12.5 ppm is 1 tsp / gallon), but nonetheless I don't think we should be promoted the routine usage of such chemicals at any dose.
Anybody wanna chime in and relieve some anxiety for me?
