When I became aware of the potential connection between the aluminum in most standard deodorant/antiperspirants and alzheimers disease, I began looking into other options. I was especially attracted to the natural mineral deodorants because they completely avoid other potentially harmful ingredients and they leave no white residue. My husband tried a roll-on mineral water product and, though it worked at first, it began to stink...it picked up bad odors when he used it on his underarm. **Spray Mist **by TCCD International avoids this issue completely by not touching your skin at all. I simply spray my freshly washed armpits (one squeeze does the trick) and let them air dry for a minute or two before dressing. Although I've never been much of a sweater, I've been very satisfied with the odor protection afforded by Spray Mist. I only shower every 3 days and it usually continues to work throughout that time. The only problem I've had with the bottle is a clogged sprayer; the minerals had hardened at the opening. I merely poked the hole with the end of a pin and the sprayer worked again.
