Why is povidone iodine a skin disinfectant?

  1. Oct 23, 2011 #1
    I know this is a well known skin disinfectant, but my note say iodine is inactivated by organic matter. Isn't skin organic matter, so how does this work. Thanks :smile:

    I remember reading an article that Dawn dish liquid was shown to be equally or more effective in removing bacteria before puncturing skin, but that Iodine has been used for so long that's it's just tradition to do so.
