Aluminium is the most common metal in the earth's crust. The aluminum salt aluminum chlorohydrate (ACH) is a compound from the group of aluminum salts obtained from pure aluminum and used as an active ingredient in antiperspirants. It narrows the sweat glands and thus inhibits sweating under the armpits. This prevents the development of unpleasant body odours and prevents the formation of wet stains on clothing. Aluminum salt-free deodorants, on the other hand, primarily prevent unpleasant odors after sweating, which are caused by bacteria on the skin, through fragrances and antibacterial agents. In addition, they can curb the growth of odor-causing bacteria and thus prevent unpleasant body odors. We offer our consumers the choice of a wide range of products, both pure deodorants and antiperspirants.
Anti-perspirants and other cosmetic products with aluminum can be used safely and without hesitation. Aluminum chlorohydrate from antiperspirants becomes an insoluble solid (aluminum hydroxide) when it comes into contact with sweat, which is practically impossible to penetrate the skin. Neither the daily use of antiperspirants with aluminum salts nor the use immediately after shaving increase the absorption of aluminum into the body. The daily use of other cosmetic products containing aluminium also does not contribute significantly to the total intake of aluminium, as recent scientific data have shown.
In March 2024, the SCCS (Scientific Advisory Panel on Consumer Safety of the EU Commission) published concentrations of aluminium in various cosmetic products that are considered safe. All Beiersdorf products are in line with the concentrations defined by the SCCS for the respective product categories.
The German Federal Institute for Risk Assessment (BfR) has clearly confirmed the safe use of aluminium in antiperspirants on the basis of the latest scientific data.
Despite decades of research, no link has been found between breast cancer and antiperspirant use, nor Alzheimer's disease and the use of antiperspirants.
