In my kits I carry both Betadine and Sterilon (Chlorhexidine gluconate). I use Betadine on regulair cuts and scrapes, but Sterilon if someone is allergic to betadine.
HTH
Btw: Betadine only has a 3-year shelf-life. Sterilon 5-years. 
I now use it as well.  I just bought some Chlorhexidine 4%(Hibiclens brand) after the vet. gave me some and it worked wonders on a wound my dog had.  Before that I had never heard of it.
