Yes, that would be right, David; 11.667 drops of 3% to deliver as much H2O2 as 1 drop of 35%. The only concern with drug store stuff would be the stabilizers often added to it. Some brands don't even have them, so check the labels and see if you get lucky. They'd be mentioned if they're there. Even with stabilizers, however, consider the dilutions you're talking about: At 600 drops per ounce (a round number) 12 drops of 3% H2O2 solution is already diluted (in 8 ounces of water) to 2.5 ppm. That means the H2O2 contained in that 3% solution would end up diluted to 350 parts per billion in your final solution. Unless the stabilizers are present in higher concentrations than the peroxide is, then the above number is a good upper limit on their possible concentration. So I tend to doubt you'd be talking about any serious toxicity with the kinds of chemicals that would be in a consumer product approved for topical use. Of course, I could be wrong, so proceed at your own risk. Be well, Mike D.
