Interesting read, @riverflows. I suffered from deodorant alergy for a long time a few years ago. I tried all sorts of different formulas and non-alcohol and no perfume and this and that. One day I simply decided to let go and stop using any at all, just cleaning the armpits with water during the day. Well, during the first weeks I did feel sweaty and stinky. However, as my body worked to clean the horrible toxins out I began to feel way better. Nowdays I don't stink anymore, nor do I need to use anything (unless I want to smell noooice).
