More Information
Summary:A smoking article having reduced ignition propensity is disclosed. The smoking article (10) includes a tobacco column (12), a wrapper (14) surrounding the tobacco column and a filter element (16). The wrapper has a base permeability, and untreated areas (20) alternating with discrete areas (22) treated with a composition to reducing the base permeability. The discretely treated areas (22) interact with a coal of a burning tobacco firecone as it advances to self-extinguish the smoking article. The composition of the treated areas includes a permeability reducing substance, a burn rate retarding substance and a burn rate accelerating substance. Either the burn rate retarding substance or the burn rate accelerating substance acts as an organoleptic enhancing substance. In this way a smoker's experience when smoking either the treated areas or the untreated areas is substantially the same.
