Deodorants without aluminium

Do Dr. Hauschka deodorants contain aluminium?

Aluminum antiperspirant ingredients are used in antiperspirants because they constrict the pores to reduce perspiration. We do not use any aluminum ingredients in Dr. Hauschka Roll-On Deodorants because we do not want to suppress the natural process of perspiring, just prevent unpleasant odors. 

Dr. Hauschka deodorants are without aluminium salts
