Low ignition propensity cigarette having oxygen donor metal oxide in the cigarette wrapper |
摘要 |
The invention relates to a low ignition propensity cigarette having a self-extinguishing cigarette wrapper which is capable of self-extinguishing the cigarette. The cigarette wrapper comprises an oxygen storage and donor metal oxide to support and maintain free-burn of the self-extinguishing cigarette while retaining the low ignition propensity property of the self-extinguishing cigarette wrapper. The invention further relates to a low sidestream smoke cigarette having low ignition propensity properties. The wrapper has a composition which reduces sidestream smoke from a burning cigarette and comprises in combination, an oxygen storage and donor metal oxide catalyst and an essentially non-combustible finely divided porous particulate adjunct for the catalyst. The sidestream smoke reducing composition reduces porosity of the wrapper to render the cigarette as self-extinguishable. The oxygen storage and donor metal oxide catalyst is in an amount which supports free burn of the cigarette while retaining the self-extinguishing property of the cigarette wrapper.
