I'm not a doctor or a scientist, so i don't know if the aluminum chlorhydrate in deodorant's contribute to diseases such as Breast Cancer or Alzheimer's, but I'm not taking any chances... That, and the fact that a good number of regular deodorants that contain aluminum make me break out in a rash...

I don't know if it's actually the aluminum chlorhydrate that cause me to break out or a coincidence though. I've done no clinical testing. LOL

I use Tom's of Maine Unscented Stick Deodorant. It does a good job for me, even on days when I work up a heavy sweat.
