Your dilution ratio seems a bit high.
About 10 times too high if it is for wound irrigation.

  • when used diluted to 1% strength, it is safe and effective for wound irrigation
And, here starting with a 4% solution it is suggested that this already dilute solution should be mixed 1:8 for topical use.
