Re: Mineral salts for body odor - this works guys! and a question...

I found this - looks like the alum is not aluminum, and they are not absorbed through the skin:

"Potassium alum molecules have a negative ionic charge, making it unable to pass through the cell wall. THEY ARE NOT ABSORBED. This is why THAI deodorants are safe to use and will not cause high levels of ALUMINUM in your system. ALUM and ALUMINUM are two different substances, with distinct chemical signatures. They possess different chemical properties which create different chemical attributes."
