I just came back from Whole Foods. Interestingly enough, I didn't see a single deodorant on their shelf that claimed to be an antiperspirant on the front.
I find it interesting that natural deodorants aren't labeled as antiperspirants. From what information I can find on antiperspirants and aluminum and its derivatives, if a product contains an aluminum derivative, it has antiperspirant qualities, no matter if it's absorbed or not.
I was trying to find out more about potassium alum, which is the active ingredient in Kiss My Face Liquid Rock roll-on deodorant, since the Delicious Organics info in your earlier post warned to look out for it. Apparently it is an aluminum derivative, but unlike aluminum, it isn't absorbed into the skin. (See the definitions presented on askwaltstollmd.com and on Wikipedia.) Also, if "mineral salts" is listed as an ingredient, it's another term for potassium alum.
The info I found seems to insinuate that potassium alum is a safer alternative to aluminum (and a few other derivatives) because it's naturally occurring and isn't absorbed into the skin. While the other option -- don't wear any deodorant at all -- is a viable one for me much of the time, I think I'll feel OK using the Kiss My Face roll-on on days where I need a little extra guard against the sweat warriors. Of course, if I can find a product with fewer ingredients, I'll opt for that; but for now I'll finish off the Liquid Rock.
