@scifreak- My son has very sensitive skin. One doctor told me to find hypoallergenic deodorant for him. I looked all over and could not find any. Later on, I had another doctor tell me to make him deodorant out of baking soda. He said making your own is "about as hypoallergenic as it gets".
So I started making the paste and it is working great! Best of all, it has no smell but yet keeps him from smelling. I agree with you scifreak--we should make more of the things we use.
