A method of making an aerosol generating material comprising an amorphous solid comprises (a) providing a slurry comprising: 1-60 wt % of a gelling agent; and 5-80 wt % of an aerosol generating agent; and optionally, 0.1-60 wt % of at least one active substance and/or flavorant; wherein these weights are calculated on a dry weight basis; (b) shaping the slurry; (c) setting the slurry to form a gel; and (d) drying the gel to form an amorphous solid. The setting agent comprises Caand one or more counterions is added to the slurry before and/or during shaping the slurry and/or setting the slurry to form the gel, the setting agent having an average molar mass of less than about 400 gmol.

Aerosol generation

An aerosol generating substrate comprising an aerosol generating material, wherein the aerosol generating material comprises an amorphous solid, the amorphous solid comprising 1-60 wt % of a gelling agent; 5-80 wt % of an aerosol generating agent; and 1-70 wt % of an active ingredient; wherein these weights are calculated on a dry weight basis; wherein bi-modal or multi-modal release of one or more active ingredients of the amorphous solid is observed in use.

An aerosol-generating amorphous solid comprising an active ingredient, wherein when a sheet of the aerosol-generating amorphous solid having an area of 43.1 mmand area density of 90 g/mis heated to 230° C. for a period of 3 seconds under a 1.1 L/min airflow, at least 50 wt % of the active ingredient is aerosolized.

Disclosed herein is an aerosol generating substrate comprising an aerosol generating material. The aerosol generating material comprises an amorphous solid. The amorphous solid comprises an active ingredient, wherein at least 70 wt % of the active ingredient aerosolised on heating of the aerosol generating material to 370° C. for a ten-second period under a 1.95 L/min airflow.

An aerosol generating substrate comprising an aerosol generating material. The aerosol generating material comprises an amorphous solid which comprises 1-60 wt % of a gelling agent, 5-80 wt % of an aerosol generating agent and optionally 0.1-60 wt % of at least one active substance and/or flavorant (dry weight basis). The amorphous solid comprises from about 1 wt % to about 15 wt % water, calculated on a wet weight basis.

A smokeable material for inclusion in a smoking article, comprising tobacco coated with acacia gum, wherein the amount of acacia gum is at least 10% by weight of the tobacco.

Material for inclusion in a smoking article

A smokeable material for inclusion in a smoking article, the material comprising particles or fragments comprising acacia gum, wherein the particles or fragments do not comprise a diluent, flavourant or aerosol generating material; and substantially comprise or consist of acacia gum.
