In issue 9 (2020), page 9, the Stiftung Warentest (leading German consumer safety group) published a short contribution titled "All-clear for aluminium in deodorants". It refers to the announcement "New studies about aluminium containing antiperspirants: Health impairments by aluminium absorption through the skin are improbable" (DOI 10.17590/20200720-103116) of the German Federal Institute for Risk Assessment (BfR; Bundesinstitut für Risikobewertung). Literally Stiftung Warentest summarizes: "On the basis of new investigations the BfR clarifies, that health impairments only by the constant use of aluminium containing antiperspirants are not to be expected." Antiperspirants contain Aluminum Chlorohydrate (INCI).
