Abstract: An aerosol-generating system is provided, including a nicotine source; a volatile delivery enhancing compound source downstream of the nicotine source and including an acid; heating means for heating the nicotine source; and a physically separate heat transfer barrier between the nicotine source and the volatile delivery enhancing compound source. The heating means is configured to heat the nicotine source to a temperature of between about 80° C. and about 150° C. The heat transfer barrier is configured so that the temperature of the volatile delivery enhancing compound source is less than about 50° C. when the nicotine source is heated to a temperature of between about 80° C. and about 150° C. by the heating means.

Abstract: An aerosol-generating article for producing an inhalable aerosol upon heating comprises a plurality of components including an aerosol-forming substrate. The aerosol-forming substrate is in the form of a hollow tubular segment defining a substrate cavity extending between an upstream end of the aerosol-forming substrate and a downstream end of the aerosol-forming substrate. The aerosol-forming substrate comprises a plurality of thermally conductive particles and an aerosol-former. The combination of tubular geometry and thermally conductive particles allows swifter time to first puff, improved efficiency of aerosol extraction and lighter weight of aerosol-generating article.
