Definitions

  • the aerosol-generating material and/or the aerosol-generating composition consists essentially of, or consists of, gelling agent; solvent; aerosol- former material; nicotine and acid. In some embodiments, the aerosol-generating material and/or the aerosol generating composition consists essentially of, or consists of, gelling agent; solvent; aerosol-former material; nicotine salt; and optionally a flavour and/or optionally an additional active substance and/or optionally filler.
  • the aerosol-generating material comprises about 15 wt% to about 80 wt% gelling agent, for example from about 20 wt%, 25 wt%, 30 wt%, 40 wt% or 45 wt% to about 65 wt%, 70 wt% or 75 wt% (all calculated on a dry weight basis).
  • the polysaccharide gelling agent is selected from alginate, pectin, starch or a derivative thereof, cellulose or a derivative thereof, and combinations thereof.
  • the polysaccharide gelling agent is selected from alginate, a cellulose derivative and combinations thereof.
  • the aerosol-generating material comprises nicotine and an acid.
  • the molar ratio of nicotine to acid is 2.2:1 or less, 1.5:1 or less or 1:1 or less.
  • the molar ratio of acid to nicotine is from 0.5:1 to 2.2:1, 0.7:1 to 2:1 or 0.7:1 to 1.5:1.
  • the aerosol-generating material may further comprise a filler.
  • a filler may help to reduce tackiness of the aerosol-generating material, for example if high levels of aerosol-former material are present.
  • the filler is fibrous.
  • the filler may be a fibrous organic filler material such as wood pulp, hemp fibre, cellulose or cellulose derivatives.
  • the filler comprises wood pulp.
  • fibrous filler in an aerosol-generating material may increase the tensile strength of the material. This may be particularly advantageous in examples wherein the aerosol-generating material is provided as a sheet, such as when an aerosol generating material sheet circumscribes a rod of aerosol-generating composition.
  • Such tensile strengths may be particularly suitable for embodiments wherein the aerosol-generating material and/or the aerosol-generating composition is formed as a sheet and then shredded and incorporated into a consumable.
  • the aerosol-generating material may have a tensile strength of from around 600 N/m to around 900 N/m, or from around 700 N/m to around 900 N/m, or around 800 N/m.
  • Such tensile strengths may be particularly suitable for embodiments wherein the aerosol-generating material and/or the aerosol-generating composition is included in a consumable/non-combustible aerosol provision system as a rolled sheet, suitably in the form of a tube.
  • the aerosol-generating material for use in aerosol generation may be present on or in a support, to form a substrate.
  • the support may, for example, be or comprise paper, card, paperboard, cardboard, reconstituted material, a plastics material, a ceramic material, a composite material, glass, a metal, or a metal alloy.
  • the support comprises (or is) a susceptor.
  • the susceptor is an aluminium sheet.
  • the susceptor is embedded within the material.
  • the susceptor is on one or either side of the material.
  • a non-combustible aerosol provision system comprising the consumable described herein and a non combustible aerosol provision device.
  • FIG. 1 and 2 there are shown a partially cut-away section view and a perspective view of an example of article consumable 101 (“article”).
  • the article 101 is adapted for use with a device having a power source and a heater.
  • the article 101 of this embodiment is particularly suitable for use with the device 1 shown in Figures 5 to 7, described below.
  • the article 101 may be removably inserted into the device shown in Figure 5 at an insertion point 20 of the device 1.
  • the article 101 of one example is in the form of a substantially cylindrical rod that includes a body of aerosol-generating composition 103 and a filter assembly 105 in the form of a rod.
  • the aerosol-generating material comprises the aerosol-generating material described herein. In some embodiments, it may be included in sheet form.
  • the filter segment 109 is between 6mm to 10mm in length, suitably 8mm.
  • a ventilation region 317 is provided in the article 301 to enable air to flow into the interior of the article 301 from the exterior of the article 301.
  • the ventilation region 317 takes the form of one or more ventilation holes 317 formed through the outer layer of the article 301.
  • the ventilation holes may be located in the cooling segment 307 to aid with the cooling of the article 301.
  • the ventilation region 317 comprises one or more rows of holes, and preferably, each row of holes is arranged circumferentially around the article 301 in a cross-section that is substantially perpendicular to a longitudinal axis of the article 301.
  • FIG. 5 to 7 there is shown an example of a device 1 arranged to heat aerosol-generating composition to volatilise at least one component of said aerosol-generating material, typically to form an aerosol which can be inhaled.
  • the device 1 is a heating device which releases compounds by heating, but not burning, the aerosol-generating material.
  • Embodiment 1 or the slurry of Embodiment 1A, comprising about 1-15 wt% nicotine.
  • the acid comprises at least one of succinic acid, lactic acid, benzoic acid, citric acid, tartartic acid, fumaric acid, levulinic acid, acetic acid, malic acid, formic acid, sorbic acid, benzoic acid, propanoic acid and pyruvic acid.
  • the aerosol-generating material or slurry of Embodiment 47 comprising about 30-55 wt% aerosol-former material.
  • Embodiment 72 The aerosol-generating material or slurry of Embodiment 71, wherein the polysaccharide gelling agent is a cellulose derivative.
  • Embodiment 106 The aerosol-generating composition of Embodiment 105, comprising from about 50-90 wt% (WWB) of the aerosol-generating material.
