A low sidestream smoke cigarette comprises a conventional tobacco rod, and a combustible treatment paper having a sidestream smoke treatment composition. The treatment composition comprises in combination, an oxygen storage and donor metal oxide oxidation catalyst and an essentially non-combustible finely divided porous particulate adjunct for said catalyst.

Low sidestream smoke cigarette with combustible paper

A device for minimizing cigarette sidestream smoke and reducing free-burn rate of a burning cigarette is disclosed. The device comprises a non-combustible tubular element encasing an effective length of a tobacco charge of a cigarette located in the tubular element. The tubular element minimizes sidestream smoke emission from a burning tobacco charge and reduces free-burn rate of such burning tobacco charge to increase the number of puffs from the burning tobacco charge.

Tubular cigarette device comprising cerium oxide

A process for making a catalytic rare earth metal oxide-coated microporous particulate material that has the rare earth metal oxide coated on outer surfaces of the microporous particulate material. The process comprises the steps of: i) combining an amount of a colloidal dispersion of rare earth metal oxide hydrate with a compatible microporous particulate material to form a slurry, the microporous particulate material having an average pore size less than the particle size of the colloidal dispersion, to position thereby, the colloidal dispersion on the outer surfaces of the microporous particulate material; and ii) heat treating the slurry to fix the rare earth metal oxide to the outer surfaces of the microporous particulate material.

Process for making metal oxide-coated microporous materials

A low sidestream smoke cigarette comprises a conventional tobacco rod and a non-combustible treatment material for the rod. The treatment material has a porosity less than about 200 Coresta units and a sidestream smoke treatment composition. The treatment composition comprises, in combination, an oxygen storage and donor metal oxide oxidation catalyst and an essentially non-combustible finely divided porous particulate adjunct for said catalyst. In addition, the invention provides a low sidestream smoke cigarette unit that comprises a cigarette with conventional cigarette paper surrounding a conventional tobacco rod and a non-combustible treatment material surrounding and being substantially in contact with the conventional cigarette paper. The non-combustible treatment material comprises a sidestream smoke treatment composition, wherein the non-combustible treatment material has a porosity less than about 200 Coresta units and the treatment composition comprises, in combination, an oxygen storage and donor metal oxide oxidation catalyst and an essentially non-combustible finely divided porous particulate adjunct for said catalyst.

Cigarette sidestream smoke and free-burn rate control device

A cigarette sidestream smoke treatment material made from a sheet of non-combustible active components provides a porous structure capable of treating sidestream smoke. The treatment material, as used in combination with a cigarette, provides a low sidestream smoke emitting cigarette unit. The material has a porosity which encourages a conventional free-burn rate of a conventional cigarette. The material may comprise a sorbent capable of sorbing components of the sidestream smoke, and an oxygen storage component which releases oxygen at free-burn rate temperatures to ensure that conventional free-burn rate is maintained and to enhance the oxidation treatment of the adsorbed non-aqueous components. Preferably, an oxidation catalyst is included in the material and most desirably the oxygen storage component may also function as the oxidation catalyst. Particularly preferred materials which perform the dual function are oxides of cerium.
