Pustular reactions to hexafluorosilicate in foam rubber

Authors


Abstract

A case is reported of a foam rubber carrier with pustular lesions on the arms, wrists, thighs and trunk. Scratch and patch testing with the foam rubber components was negative. Animal testing revealed sodium hexafluorosilicate (Na2SiF6) one of the ingredients of the foam rubber, to be a pustulogen on previously damaged skin.
