ABSTRACT:
A cigarette filter containing menthol or other smoke-flavoring agent, and having improved shelf life and delivery rates for the smoke-flavoring agent, is obtained by first impegnating a granular activated carbon with a pore-modifying agent capable of blocking the most retentive portions of the activated carbon, by being held in preference to the smoke-flavoring agent which is added later. The pore-modifying agent is employed in amounts such that the less retentive portions of the activated carbon are not blocked but remain available for adsorption of the smoke-flavoring agent. A preferred pore-modifying agent is sucrose. Subsequently, the activated carbon is impregnated with the smoke-flavoring agent. The granular activated carbon is then formed into a filter.
