Housing and cartomiser for an aerosol provision system

Abstract

The present disclosure relates to a housing for an aerosol provision system. The housing comprising a reservoir for an electrically conductive aerosolisable material, wherein the potential difference between any two exposed and/or exposable surfaces of one or more metal components which are contained in the housing, is from 0 mV to about 35 mV, wherein the two surfaces are capable of simultaneously being in contact with the aerosolisable material. Also disclosed is a cartomiser comprising a reservoir containing an electrically conductive aerosolisable material, and two exposed and/or exposable surfaces of one or more metal components, wherein the two surfaces are capable of simultaneously being in contact with the electrically conductive aerosolisable material and wherein the change in dissolved metal content of the electrically conductive aerosolisable material after storage of the cartomiser for about 1 to about 8 weeks at about 40° C. is between 0 and about 20%.
