Gillette Power Stuff

Hey,
I was wondering what exactly you put in the power stripe of your "gillette power stripe deodorant." I've been trying it out since I received some for christmas, but it's not good. It burns my underarms. I never shaved my armpits before, and now it looks like I did. Don't get me wrong; I'm a fan of gillette, but I think you should re-evaluate the chemicals you're putting in the power stripe. I cannot use power stripe anymore and I just wanted to understand why.
Thanks,

(PS, i hear anti-persperant gives you cancer, maybe you can elaborate on that too.)
