Abstract
A smoking article having reduced ignition propensity is disclosed. The smoking article includes a tobacco column, a wrapper surrounding the tobacco column and a filter element. The wrapper has a base permeability, an untreated area and a least one discrete area treated with a composition to reduce the base permeability. The treated area is treated with a composition initially comprising a permeability reducing substance initially dissolved in a non-derivatizing solvent mixture initially comprising a solvent component and at least one ingredient that as part of the solvent mixture is a self-association disruptor for the permeability reducing substance. The discretely treated area interacts with a coal of a burning tobacco firecone as it advances to self-extinguish the smoking article. The composition of the treated area includes a permeability reducing substance.
