Penetration of aluminium salts through pig skin in vitro
Background: Recently it was suggested to use aluminium chloride hexahydrate in petrolatum at 10% to detect aluminium contact allergy. Patch testing with aluminium chloride hexahydrate at 20% did not demonstrate a higher number of positive test reactions. It was speculated that the constricting effect of aluminium salts might impair skin penetration. Objectives: The purpose of the present study is
