Abstract: A capsule for use in a smoking article includes a liquid sensory enhancing material; and a shell surrounding the liquid sensory enhancing material. The shell has an outer surface rendered hydrophobic by hydrophobic groups covalently bond to the outer surface of the shell. The shell may be rendered hydrophobic by reacting hydroxyl groups at outer surface of the shell with fatty acid halides to covalently attach fatty acid moieties to the surface of the capsule.

Abstract: An aerosol-generating article for producing an inhalable aerosol upon heating is provided, the aerosol-generating article including: a rod of aerosol-generating substrate, the aerosol-generating substrate including homogenised plant material including tobacco particles and at least 2.5 percent by weight of non-tobacco plant flavour particles, on a dry weight basis, the non-tobacco plant flavour particles including particles of eucalyptus, star anise, clove, ginger, rosemary, or combinations thereof; an upstream element upstream of the rod of aerosol-generating substrate and abutting an upstream end of the rod of aerosol-generating substrate; and a downstream section arranged downstream of the rod of aerosol-generating substrate and in axial alignment with the rod of aerosol-generating substrate, the downstream section including one or more downstream elements.

Abstract: A smoking article includes a tobacco substrate and a filter segment comprising filtration material axially aligned in an abutting end to end relationship with the tobacco substrate. A hydrophobic plug wrap is disposed about the filtration material. The plug wrap is hydrophobic via hydrophobic groups chemically bonded to the plug wrap.

Abstract: A smoking article includes a tobacco substrate and a mouthpiece axially aligned in an abutting end to end relationship with the tobacco substrate. Hydrophobic tipping paper is disposed about the mouthpiece. The tipping paper is hydrophobic due to hydrophobic groups covalently bonded to the tipping paper.

Abstract: A capsule (120) for use in a smoking article includes a liquid sensory enhancing material; and a shell surrounding the liquid sensory enhancing material. The shell has an outer surface rendered hydrophobic by hydrophobic groups covalently bond to the outer surface of the shell. The shell may be rendered hydrophobic by reacting hydroxyl groups at outer surface of the shell with fatty acid halides to covalently attach fatty acid moieties to the surface of the capsule.

Abstract: A smoking article tube includes an elongated tube having a mouthpiece segment at a first end and an empty smokable material cavity defined by a second end of the elongated tube opposing the first end. A hydrophobic tube region includes hydrophobic groups covalently bonded to the elongated tube.

Abstract: A smoking article (10) includes a tobacco substrate (20) comprising at least 15% humectant and a hydrophobic paper wrapper (40) disposed about the tobacco substrate. The paper wrapper (40) is hydrophobic due to hydrophobic groups covalently bonded to the paper.

Abstract: A smoking article includes a tobacco rod and a wrapper disposed about the tobacco rod. The wrapper includes a plurality of aggregated particles. The aggregated particles include particles of functional material and a whitener bound in a polymeric binder. The particles of functional material may be a catalyst or an oxidant, such as an iron oxide-containing particle. The whitener may be calcium carbonate.

Abstract: A smoking article includes a tobacco substrate and a wrapper disposed about the tobacco substrate. At least an inner or outer surface of the wrapper is hydrophobic via hydrophobic groups chemically bonded to the wrapper. The wrapper has a permeability of at least about 15 CORESTA units.
