This question concerns your deodorant stone. I only recently became aware that it contains aluminum. Your website contains the statement "Other Ingredients: Aluminum Sulfate*. Please explain.
Topically-applied, naturally-occurring aluminum crystals are minimally absorbed, typically less than 0.015 %.1 The form found in NOW Deodorant Stones (aluminum sulfate, or "alum salt") is considered less likely to cause skin problems than other forms of aluminum found in commercial deodorants/antiperspirants (aluminum chloride, aluminum zirconium tetrachlorohydrex etc.) and has lower absorption potential, two reasons why natural deodorant stones have become popular.
