Definitions

• the present invention concerns a tobacco substitute, the use thereof and a method for the production thereof.
• tobacco usually employed in tobacco goods of all kinds alternative tobacco systems have also been known for some time, by means of which flavoring substances and/or active substances can be consumed in the form of aerosols, that is to say smoke or vapor.
• tobacco also include inter alia nicotine-free herbs but also further in particular mineral carrier materials like for example vapor stones which are coated with aromatized fluid, for example flavor syrup or so-called molasses or treacle.
• mineral carrier materials like for example vapor stones which are coated with aromatized fluid, for example flavor syrup or so-called molasses or treacle.
• carrier materials can be portioned and are suitable for putting the aromatized fluid into an inhalable administration form.
• carrier materials are used inter alia in waterpipes (shishas), conventional tobacco pipes and electronic cigarettes, so-called e-cigarettes.
• WO 2011/120518 discloses as the carrier material a stone which has pores and which contains at least 65% of clinoptilolite and is charged with a fluid which forms an aerosol in the waterpipe.
• DE 10 2007 033 083 discloses a tobacco substitute which as carrier materials has inter alia fiber materials, foams and loose materials like montmorillonite, dolomite or kieselguhr.
• a tobacco substitute in particular for use in a waterpipe (shisha), tobacco pipe or electronic cigarette, which includes a liquid fluid and a carrier material for the fluid, characterised in that the carrier material includes apatite.
• a further advantage of using apatite as the carrier material or a constituent of the carrier material is that it remains unchanged under temperatures in the region of between 100 and 350° C., that are usually employed in smoking uses, and thus does not transfer into the aerosol or the vapor formed. For that reason there is also the possibility of charging apatite as the carrier material with fluid again after a use so that the carrier material is re-usable.
• fluid or “liquid fluid” or “substantially liquid fluid” denotes in accordance with this invention fluids which at room temperature (18° C.) and normal pressure (1.01325 bar) are in a fluid physical state.
• the fluid includes water, one or more polyols, one or more sugars, one or more coloring agents, one or more flavor substances and/or active substances.
• polyols which are suitable according to the invention include but are not limited to glycerin, propylene glycol and mixtures thereof.
• glucose can be used as the sugar.
• the fluid includes one or more active substances and/or flavor substances.
• active substances and flavor substances include extracted and/or synthetic plant substances, including those from fruits, herbs, fruit products as well as plant products and mixtures thereof, for example also caffeine and nicotine. Active substances and flavor substances can be present for example in the form of esters, ethers, oils, monovalent alcohols or mixtures thereof.
• Fluids which are suitable and can be used according to the invention are also commercially available for use with vapor stones and are also referred to as flavor syrups, molasses or treacle.
• aerosol as is used here relates to solid and/or liquid particles which are very finely distributed in a gas. If exclusively liquid particles are involved the aerosol is also referred as vapor. If substantially solid particles are involved the aerosol is also referred as smoke.
• apatite denotes calcium phosphates like hydroxylapatite (Ca 5 (PO 4 ) 3 OH), fluoroapatite (Ca 5 (PO 4 ) 3 F), chloroapatite (Ca 5 (PO 4 ) 3 Cl), carbonate-bearing apatites and further naturally occurring and/or synthetically produced apatites.
• the apatite is hydroxylapatite.
• the carrier material has an apatite proportion of between 70% by weight and 100% by weight, preferably between 80% by weight and 100% by weight, particularly preferably between 90% by weight and 100% by weight, with respect to the total weight of the uncharged carrier material.
• the carrier material consists of apatite. It has been found that apatite can be used substantially as the exclusive carrier material and is inert in respect of taste and in regard to the production of the aerosol.
• the carrier material optionally has additives.
• additives include but are not limited to stearates, in particular magnesium stearate, polyethylene glycols, polyethylene oxides and talcum.
• the additives can advantageously be used as tabletting additives.
• the apatite has a specific surface area of more than 60 m 2 /g, preferably more than 70 m 2 /g, measured using the BET method in accordance with DIN-ISO 9277 2003-05. In an embodiment the apatite has a specific surface area of up to 250 m 2 /g.
• the proportion of fluid to the carrier material is between 2% by weight and 55% by weight, particularly preferably between 5% by weight and 30% by weight, with respect to the total weight of the carrier material with fluid. It has been found that with that ratio by weight a particularly good and long-lasting aerosol production is achieved.
• the carrier material is in the form of a pressed tablet.
• tablette refers to a pressed shaped item which is produced under pressure in tablet presses which are known to the man skilled in the art for that purpose or other press assemblies.
• the pressing pressure which is preferably used for the production of such tablets is advantageously in the region of between 60 MPa and 300 MPa with an optional pre-pressing pressure of between 20 MPa and 100 MPa.
• the table is of a cylindrical or biconvex shape with a diameter in the range of between 2 mm and 2 cm.
• the term “biconvex shape” refers generally to a shape which is substantially round in a view from below or above and which is curved upwardly and downwardly.
• a substantially round shape can include a circular shape but also slight deviations therefrom including regular polygons (triangles, quadrilaterals, pentagons, hexagons, heptagons, octagons, etc) as well as oval shapes.
• regular polygons triangles, quadrilaterals, pentagons, hexagons, heptagons, octagons, etc
• oval shapes oval shapes.
• the tobacco substitute is in a form obtained by extrusion, compacting, 3D printing or injection molding. These methods provide a greater variability in shape.
• the fluid has a water content in the region of between 0% by weight and 50% by weight, with respect to the total volume of the fluid, preferably between 0.5% by weight and 10% by weight.
• the invention further includes the use of apatite in a carrier material for a fluid in a tobacco substitute with the properties and features described herein.
• apatite is used as the carrier material for a fluid in a tobacco substitute.
• the invention further includes the use of the tobacco substitute described herein in a tobacco pipe or waterpipe (shisha).

• apatite and optionally additives are provided in a mixer with agitation
• the fluid in a second step the fluid is added with continued agitation and blended with the provided apatite and optionally additives, and
• the resulting mass is shaped or pressed to form tablets.
• a vacuum is further applied, which is maintained in the second step.
• the vacuum provides that the fluid is drawn into the mixer.
• the shaping operation in the third step can be effected by extrusion, compacting or injection molding.
• tablets of a diameter in the region of between 2 mm and 2 cm are produced, wherein a pressing pressure of between 60 MPa and 300 MPa is used and optionally a pre-pressing pressure of between 20 and 100 MPa.
• a hydroxylapatite having a specific surface area of 80 m 2 /g (CAS-No 1306-06-5: which can be obtained from Chemische Fabrik Budenheim KG, Budenheim, Germany), is charged with a commercially available flavor fluid which contains glycerin, glucose, water, natural flavors and food dye (raspberry flavor fluid, which can be obtained from Aladin Shisha, Wiesbaden, Germany, website: www.bigg-steam.com).
