Tade Natural Polished Alum Stone
Tade Natural Polished Alum Stone claims to be 100% natural alum, and act as a body deodorant by reducing sweat causing odor, also relieving razor burn and tightening and lifting skin.
To begin, alum, which is what natural deodorant stones are made of, does occur naturally, and is mined in quarries throughout the world. The difficulty in verifying whether it is natural or not lies in the fact that alum can be synthetically manufactured to form the identical chemical composition as its natural counterpart. However, synthetic alum is far from natural as it is made by reacting Aluminium trihydroxide (ATH) and acid.
So, I based my findings not on the chemical composition, which however is very important, but on the visual appearance of the stone, which my skill set is better suited for as I am not a chemist.
