Description

[0030] Exemplary embodiments of the invention are explained hereinafter on the basis of a schematically represented FIGURE, but without thereby restricting the invention. In this situation the single FIGURE shows a schematically greatly enlarged representation of a tobacco substitute-fluid mixture according to the invention in a cross-sectional view.

[0031] The tobacco substitute-fluid mixture includes a fluid 1 in which particles 2 of a thickening agent 2 or, respectively, two or more different thickening agents 2 are distributed. The thickening agent 2 consists of different inorganic layer silicates with an average grain size of less than 2 μm. The fluid consists of a mixture of 5% by weight water, 70% by weight glycerin, and 20% by weight 1,2-propanediol. Additionally included in the fluid are some 5% by weight aromatic agents 4 and caffeine 6 and/or nicotine 6, which are likewise distributed in the fluid.

[0032] The tobacco substitute-fluid mixture includes such a concentration of particles 2 of the thickening agent 2 that it has a viscosity of at least 10 N m s.sup.−2 at a temperature of 200° C. Preferably, the tobacco substitute-fluid mixture has a viscosity of 10 N m s.sup.−2 to 100 N m s.sup.−2. The tobacco substitute-fluid mixture is produced in that 75% by weight glycerin, containing water, and 25% by weight 1,2-propanediol, including the aromatic agents 4 and/or the psychoactive substances such as caffeine 6 or nicotine 6, are mixed. Next, the aromatic agents 4 and the caffeine 6 and/or the nicotine 6 are mixed in. After this, kaolin is mixed into the fluid 1 produced in this way, which includes the particles 2 of the layer silicate. As an alternative, other mixtures of layer silicates or hydrated SiO.sub.2 particles with an average grain size of less than 5 μm can be added as particles.

[0033] The particles 2 of the inorganic thickening agent 2 are then intensively mixed with the fluid 1, in order to attain a uniform distribution of the particles 2 in the fluid 1, or, respectively, in order to attain a dispersion of the particles 2 in the fluid 1.

[0034] In this case, the water from the fluid 1 is in stored in the particles 2 of the layer silicate or is absorbed and bound by the layer silicates. In particular, in this case it is in the “book side borders” of the particles 2 of the layer silicates of the kaolin that the fluid or the water, the glycerin, and/or the 1,2-propanediol are stored. As a result, the viscosity of the tobacco substitute-fluid mixture is increased. For an adequate viscosity it can already be sufficient if 30% by weight kaolin is mixed with 70% by weight of the fluid 1.

[0035] The features of the invention disclosed in the foregoing description, as well as in the claims, FIGURES, and exemplary embodiments, can be essential both individually as well as in any desired combination for the realization of the invention in its different embodiments.
