(Inci:Potassium Alum)

Alum stone is a natural mineral ingredient. Unlike aluminum chlorhydrate or aluminum zirconium compounds commonly used in deodorants, alum stone powder is charged in negative ions, therefore, it doesn't penetrate the cell membrane and is not absorbed by the body and won't increase aluminium levels in the body.Use between 3% and 10% in deodorants with Farnesol and Lemonester.
