TOBACCO SUBSTITUTE, USE AND METHOD FOR THE PRODUCTION THEREOF

Abstract

A tobacco substitute, in particular for use in a waterpipe (shisha), tobacco pipe or electronic cigarette, including a liquid fluid and a carrier material for the fluid is disclosed. To provide a tobacco substitute which forms a denser vapor or denser aerosol in comparison with known tobacco substitute systems, the carrier material of the tobacco substitute includes apatite.

Description

EXAMPLES

Example 1

Aerosol Development and Flavor

[0032] In this example aerosol development of different tobaccos and tobacco substitute materials were compared together.

[0033] For that purpose a hydroxylapatite having a specific surface area of 80 m.sup.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). The apatite charged with the flavor fluid was used in the form of a mass pressed to constitute tablets (sample b)). In a further approach a tablet which had already been used in accordance with sample b) was charged again with flavor fluid (sample d)).

[0034] In sample b), prior to the tabletting step, the apatite was charged with 25% by weight of flavor fluid, with respect to the total weight of apatite and flavor fluid. The tablets used in sample d) were produced as for sample b) and after a use as described below in a waterpipe introduced again into flavor fluid, with a marked excess of flavor fluid being used.

[0035] After blending of the constituents for sample b) and sample d) respectively prior to the first use the mass was pressed in a tablet press under a pressing pressure of 210 MPa to constitute tablets.

[0036] As comparative samples vapor stones (Shiazo Steam Stones Raspberry, Shiazo/ASA GmbH) in sample a) and waterpipe tobacco (Al Ajamy Kirsch Aroma) in sample c) were used.

[0037] For the test, a waterpipe bowl was filled with the materials specified in Table 1, covered with a perforated aluminum film and a vapor or aerosol development operation was initiated by applying glowing coal.

[0038] The operation of ascertaining the aerosol density was effected by optical comparison and the flavor developed was subjectively assessed by four test persons. Evaluation was effected within a 30 minute period of time after ignition of the waterpipe.

[0039] Assessment was effected by specifying better (+), equal (0) and worse (−) in comparison with sample b) as the reference. The results of the test are set out in Table 1, the last column specifying the respective assessments of the four test persons.

TABLE-US-00001 TABLE 1 Sample Material Aerosol density Flavor/taste a) Vapor stone in Very thin −/−/0/+ flavor fluid b) Tablets, 25% Very dense 0/0/0/0 flavor fluid (reference) c) Aromatized Very dense 0/0/+/+ waterpipe tobacco d) Tablets, re-used Very dense 0/+/0/0

[0040] The test persons assessed the tobacco substitute according to the invention which was used as sample b) in respect of flavor/taste as well as aerosol formation as being similar to the conventionally employed aromatized waterpipe tobacco, but could at least not attribute thereto any marked advantages over the tobacco substitute of sample b).

[0041] A conventional commercially available tobacco substitute (sample a)) which was also used in the test was assessed both in respect of aerosol development and also flavor/taste as being worse than a tobacco substitute according to the invention.

[0042] In addition even the re-used tobacco substitute of sample d) was assessed as being similarly positive to sample b).

[0043] In addition to the results set out in Table 1 it was noted that tablets according to the invention which had already been used can remain for up to two hours in flavor fluid without degrading. This confirms that the tablets according to the invention after use can be again charged with fluid and used.

Example 2

Long-Term Apatite Tablets Charged with Flavor Fluid

[0044] This experiment involved testing whether a carrier material including apatite is capable of providing a tobacco-like smoking experience during a period of time which is usual for consumption using a waterpipe.

[0045] The tablets used for this test and charged with flavor fluid were of the following composition:

[0046] 75% by weight of hydroxylapatite (with a specific surface area of 80 m.sup.2/g, from Chemische Fabrik Budenheim KG), and

[0047] 25% by weight of flavor fluid (raspberry fluid, www.bigg-steam.com)

[0048] For production of the tablets the apatite was charged with the flavor fluid by means of a Stephan mixer. The apatite was put in the mixer. The flavor fluid was then added by way of a funnel. The fluid was uniformly distributed in the apatite by the mixing operation. The charging operation lasted for 5 minutes. The apparatus was then opened and small residues on the cover were returned to the mixture. A 1-minute post-mixing phase was effected.

[0049] Tabletting was effected in a tablet press (Fette 102i, Fette Compacting GmbH, Schwarzenbek, Germany) under a pressing pressure of 105 MPa. The finished tablets on average were of a mass of 396.1 mg and had a breaking strength of 106 N (measured on a tablet tester from ERWEKA GmbH, Heusenstamm, Germany).

[0050] In the test a waterpipe bowl was filled with waterpipe tobacco (sample aa)), tablets (sample bb)) or commercially available vapor stones (sample cc)), Aladin Shisha, Wiesbaden, Germany, website: www.shiazo.com), covered with a perforated aluminum film and vapor development was started by applying glowing coal. All samples were consumed with the usual period of time of 45-60 minutes.

[0051] Assessment was effected as described above for example 1, the pipe tobacco serving as a reference. The results are set out in Table 2:

TABLE-US-00002 TABLE 2 Sample Material Aerosol density Comments aa) Waterpipe Dense Dense vapor. After 55 tobacco with minutes still a pleasant raspberry taste, no rasping in the flavor throat bb) Tablets, 25% Dense Right at the beginning flavor fluid dense vapor development (30 seconds), after 45 minutes the flavor was weaker and the vapor less dense cc) Vapor stones Thin In the first 2 minutes with raspberry very thin vapor, no flavor flavor. After 5 minutes the vapor became denser but less strongly than with the tobacco. After 45 minutes the flavor became weaker and the vapor density decreased.

[0052] As in example 1 sample b), when using sample bb) it was possible to provide a dense aerosol subjectively comparable to the conventional tobacco (sample aa)). The duration of the possible use at 45 minutes is approximately as long as with conventional waterpipe tobacco which generally can be used for about 60 minutes. With conventional vapor stones the vapor density was less high. In addition with sample bb) dense vapor development could be observed immediately while with sample cc) a noticeable vapor development was found to occur only after 5 minutes.
