Deodorants without aluminium

Do Dr. Hauschka deodorants contain soluble aluminium salts?

Soluble aluminium salts are used in conventional antiperspirants because they constrict the pores and therefore reduce perspiration. Dr. Hauschka Roll-On Deodorants are made without aluminium salts because we do not want to suppress the natural process of perspiring but only to prevent unpleasant odours.
