Abstract
The invention relates to a reconstituted smoking material which comprises a non-polyol aerosol generator, tobacco (optional), binder (optional) and inorganic filler. A further polyol aerosol generator may also be contained in the smoking material. There is also provided a smoking article containing such material in a conventional arrangement or with a core axially disposed within an annulus. A further aspect of the invention is the provision of a polyol or non-polyol aerosol generated disposed in the filter element of a smoking article, which may contain the inventive smoking material. The aerosol material on the filter is eluted into the aerosol of the smoke on burning of the smoking article.
Claims19
A smoking material comprising from 6 to 30% by weight of a non-polyol aerosol generator, selected from the group consisting of triethylene glycol diacetate, glycerol triacetate, glycerol diacetate or a combination thereof, up to 20% by weight tobacco, binder at not more than 20% by weight and not less than 30% by weight inorganic filler of calcium carbonate.
A smoking material comprising from 6 to 30% by weight of a non-polyol aerosol generator, the total amount of aerosol generator being about 30% or less, no tobacco, binder at less than 10% by weight and not less than 30% by weight inorganic filler of calcium carbonate.
A smoking material consisting essentially of:
- a. an aerosol generator, being present at from about 2% to about 30% by weight, said aerosol generator comprising:
- i. a non-polyol aerosol generator, selected from the group consisting of triethylene glycol diacetate, glycerol triacetate, glycerol diacetate or a combination thereof, said non-polyol aerosol generator being present at from about 6% to 30% by weight;
- and
- ii. a polyol aerosol generator, selected from the group consisting of glycerol, triethylene glycol, propylene glycol, polyhydric acid, and ester, a high boiling point hydrocarbon, methylene glycol, methyl citrate or a combination thereof, said polyol aerosol generator being present at less than 24% by weight;
- b. tobacco, being present at less than 20% by weight;
- c. binder, being present at less than 20% by weight;
- d. inorganic filler of calcium carbonate, being present at greater than 30% by weight;
- and
- e. an additive selected from the group consisting of cocoa, sugar, fibre, starch, pullulan, polysaccharide expansion agents, foaming agents, cocoa butter, olive oil, corn oil, or a combination thereof, being present at less than 25% by weight.
