Alum As Antiperspirant


A question about alum from Alice.

Hello Colin,

Thank you for taking the time to write such a informative blog. I have a question concering potassium alum. I have been researching this product and I keep seeing comments like “its a compound” so it does not contain aluminium. KAl(SO4)2  does contain potassium and aluminium so can you please explain to me (us) if there is Al in here for those of us who try to steer clear of this stuff in our deo/antiperspirants. Thank you very much. Kind regards, Alice
