Aluminum chloride is commonly used topical antiperspirant. It is proposed that aluminum chloride works by causing an obstruction of the distal sweat gland ducts, where the metal ions precipitate with mucopolysaccharides, damaging epithelial cells along the lumen of the duct and forming a plug that blocks sweat output [A32368].
