Unlike the lung, the skin provides a good barrier against particles. In animal tests aluminium oxide particles (Al2O3) did not cause irritations of the skin of animals.

 

Aluminium (aluminum salts) is used in roll-on deodorants due to its anti-perspirant effect. Al2O3 tested according to OECD Guideline 404 "Acute Dermal Irritation/Corrosion" [3] in animal experiments does not cause irritations of the skin of animals. The maximum recommended daily aluminum ion uptake through the use of roll-ons is 7 µg, which is considered to be non-hazardous to health [2].
