New human study by BfR shows: Aluminum absorption from antiperspirants significantly lower

Aluminum salts are used in antiperspirants with the aim of blocking sweat flow and inhibiting odor formation. Until recently, it was unclear how much aluminum is absorbed through the skin. Currently, there are three human studies from 2001, 2016, and 2019 on aluminum absorption through the skin (dermal absorption or bioavailability) from antiperspirants, which are based on measuring the aluminum concentration in the blood and/or urine.

Only the 2019 human study provides a reliable figure for absorption rate/bioavailability. Based on this value, the BfR has extrapolated the amount absorbed through the skin in its current risk assessment, with the result that aluminum from antiperspirants does not contribute significantly to the overall exposure to aluminum.

Rather, a high aluminum intake is expected from the consumption of acidic and salty foods that come into contact with aluminum materials, such as baking trays or grill pans.

According to the current state of scientific knowledge, high aluminum exposures can have negative effects on the nervous system, kidneys, and bones.

The BAV Institute and its Tentamus laboratory partners analyze aluminum content in cosmetics for you using state-of-the-art methods. Many other chemical parameters, including heavy metals, phthalates, or pesticide residues, are also part of our portfolio. Contact us, we look forward to hearing from you!
