Abstract

L'invention concerne un filtre à tabac utile pour éliminer sélectivement et efficacement le formaldéhyde tout en conservant les éléments gustatifs du tabac, tels que la nicotine et le goudron. Le filtre à tabac de l'invention est fabriqué avec une composition constituée d'au moins un composé amino choisi parmi des aminoacides et des acides aminosulfoniques et un gel de silice (en particulier un gel de silice de diamètre des pores moyen d'au moins 20 nm). Cette composition peut en outre contenir un agent hydratant tel que l'un quelconque des polyols. Ce filtre à tabac peut éliminer sélectivement et efficacement le formaldéhyde, selon notamment un taux de rétention du formaldéhyde d'au plus 50% tout en conservant aussi bien la nicotine que le goudron à un taux d'au moins 75%.
