Definitions
- the invention relates to a filter cigarette, the filter of which contains an additive with an anti-mutagenic effect on cigarette smoke.
- Antimutagenic active ingredients are known from food technology. There, many of the mutagens found in foodstuffs and their separation mechanisms are also examined and illustrated (see, inter alia, P. Grasso, CO 'Hare; Chemical Carcinogens ACS Monograph (Ch. E. Searle ed.), American Chemical Society, Washington (1976 ), Pp. 700 - 728). Some pyrolysis products of proteins are regarded as the most effective mutagens in food today, e.g. the connections Tr-Pl, Tr-P2, Glu-Pl, Glu-P2 or also IQ (see, among others, K. Wakabayashi,
- Such compounds can obviously be bound in living organisms with high efficiency in the aqueous phase to constituents of mostly plant-based foods and thus effectively removed from the metabolism as water-insoluble complex compounds.
- antimutagenic substances include chlorophylline and hemin and related derivatives (see, inter alia, R. Dashwood, D. Gno; Environmental and Molecular Mutagenesis, 22, (1993), pp. 166-171, S. Arimoto, H. Hayatsu; Mutation Research, 213, (1989), pp. 217-226, and Kato et al., Mutation Research, 246, (1991), pp. 169-178).
- the mutagenic effect of cigarette smoke determined by the Ames test, is generally known in the art.
- DE-PS 1 300 854 describes the use of acidic carboxylic acid alkyl esters as crosslinking or strengthening agents.
- a number of other publications on the use of organic acids as a filter additive are based on the disclosure of this patent in order to specifically increase nicotine retention.
- the special thing about this idea is that the additive also acts as a plasticizer and thus an industrial production of
- DE-PS 1 300 854 does not disclose any indication of how mutagenic substances could be removed from cigarette smoke.
- the effectiveness of the filter additives described in DE-PS 1 300 854 in a filter tow was demonstrated on one with a filament titer of more than 3 dtex.
- DE-PS 1 300 854 nor DE-OS 43 20 384 make any statements about a possible reduction in the biological activity in the Ames test of cigarette smoke.
- DE-OS 25 27 234, JP 50-125100 and JP 51-32799 describe the use of cyclodextrin, in particular ⁇ -cyclodextrin, for the filtration of in particular nicotine.
- This additive can be applied directly to cellulose acetate filters or as granules in chamber filters.
- the amounts described are extremely high, 30 to 80 mg per filter according to the two Japanese applications and "mainly or exclusively" according to the specifications of DE-OS 25 27 234. A possible reduction in the biological activity of the smoke is not reported.
- US Pat. No. 5,409,021 describes a cigarette filter as a double or triple chamber filter, in which the chamber contains lignin as filler material.
- the amounts of effective lignin mentioned in the examples are between 22 and 66 mg.
- the known filter is effective against nicotine, benzpyrene, CO, metals and tobacco-specific nitrosamines.
- the reduction in biological activity according to the Ames test (TA 98) is not addressed.
- the amounts of additive used are around 20 to 50% of the filter fiber weight.
- EP-A-0 493 026 describes the impregnation of a cellulose acetate filter with an N, N'-bis (3-triethoxysilyl-propyl) thiocarbamide monomer in concentrations of 6 to 15%. The measure results in an increased filter efficiency compared to polycyclic
- Aromatics, metals and tobacco-specific nitrosamines No statements are made about the retention of the filter used. Also, no effects on the biological activity of the smoke are dealt with in the Ames test (TA 98).
- Russian patent 2 010 546 describes a combination of the teachings according to EP-A-0 493 026 and US patent 5 409 021.
- JP-5-23159 describes a cigarette filter with ellagic acid as an additive. Here, their antimutagenic effect is also addressed.
- the recommended amount of additive is 1 to 10 mg per filter. Its antimutagenic effect according to the Ames test (TA 98) is not proven.
- EP-A-0 246 330 describes the reduction of the mutagenicity in the Ames test (TA 98) by activated cellulose powder, cellulose ion exchangers or by hemin-doped celluloses in powder form.
- the examples only describe chamber filters.
- the amount of powder that is required to achieve a reduction in the specific mutagenicity of more than 10% is well above 15%, based on the filter fiber weight used.
- the additive should also be able to be sprinkled between the acetate fibers of a monofilter. None more is said about the effectiveness of this measure. Tests have shown that only with an amount of additive of significantly more than 10 mg per filter does an effect in the
- Ames test (TA 98) of more than 10% can be achieved.
- the invention has for its object to provide a filter cigarette of the type described, in which the tobacco smoke is filtered such that, measured according to the Ames test with the TA 98 strain, mutagenic substances with a Selectivity of at least 10%, especially more than 20%, better than other smoke ingredients.
- the invention is also intended to propose a particularly suitable method of how the additive is applied to the filter.
- this object is achieved by a filter cigarette, the filter of which contains an additive with an antimutagenic effect on cigarette smoke, the
- Filter a) contains fibrous filter material, b) the additive in an amount of less than 15% by mass, based on the Fiber weight of the filter, and c) has a nicotine retention RN (in%) when smoking a similar, but not containing additive, unventilated filter cigarette (determined according to CORESTA, recommended method No.9), which satisfies the following formula: R N > 100 * (1-D) where:
- the filter design is of crucial importance. It has surprisingly been found that a minimum retention is required for the effectiveness of the measures according to the invention, which is rarely achieved with filters in cigarettes commercially available today.
- the nicotine retention is used as a reference variable as retention.
- the filtration performance of a cigarette filter is, in addition to the material properties of the filter material, the dimensions of the filter, such as diameter and filter length, and the pressure drop in the filter (the term is used in the cigarette industry
- the required filtration performance of a filter and here in particular the nicotine retention can be expressed by the following empirically determined equation: R N > 100 * (1-D), (I) where nicotine retention (in percent) and D represents the permeability of the filter to nicotine.
- the permeability of a filter with regard to nicotine results from the following equation:
- variable A describes the dependence of the filter performance on the filter length.
- the variable A is calculated by subtracting the actual filter length I from the length of a king-size filter I 0 .
- variable C describes the dependence of the filter performance on diameter and draw resistance:
- the CORESTA Monitor Cigarette No. is used for the smoke to determine the minimum retention. 2 (see Coresta Approved Monitor No. 2 (CM2) from borgwaldt technik D - 22525 Hamburg). However, since this product is only defined for one diameter, tobacco strands made of identical tobacco (flue cured), strand paper, casing and tobacco density are used for other cigarette diameters. Since nicotine retention is independent of the strand dimensions and the nicotine retention of cigarette filters when using flue cured tobacco is identical to condensate retention (G. Lipp: Contributions to Tobacco Research 3, 109 (1965)), the procedure for determining retention is not critical .
- fibrous filter material used in the filter cigarettes according to the invention is not critical.
- these materials can be fibers made of polypropylene, viscose, polyester and, in particular, cellulosic materials.
- Cellulose acetate is particularly preferred.
- the fibrous filter materials can be used in the form of a filter tow or a fleece. It is particularly advantageous if a filter tow consists of a cellulose acetate.
- a nonwoven it preferably consists of paper, but nonwovens made of highly fibrillated cellulosic fibers or so-called meltblown nonwovens and spunbonded nonwovens can also be used become.
- this preferably contains staple fibers and / or filaments with a titer of less than 3 dtex, in particular from 1.0 to 2.7 dtex. In this case, a particularly good filter effect is achieved.
- the desired filter effect is also increased by the fact that the filter is ventilated.
- a filter for further explanation of a filter, reference is made to EP-B-0 368 065. From this it is known that in ventilated cigarettes the separation of volatile, in particular steam-volatile, substances increases with an increasing degree of ventilation. In the context of the invention, a degree of ventilation of at least 15%, in particular from 20 to 70%, is advantageous.
- the additive is present in the filter cigarette in an amount of less than 15% by mass, based on the fiber weight of the filter.
- This low proportion is surprising and is only possible due to the special filter construction which characterizes the filter cigarette according to the invention.
- This value can be significantly reduced if the additives are selected advantageously. It is possible and advantageous in individual cases if the additive is present in an amount of less than 10% by mass, in particular less than 7% by mass, based on the fiber weight of the filter. The minimum value is about 0.5% by mass, based on the fiber weight of the filter.
- Various groups of compounds which have a selective filtering action against the pyrolysis products of amino acids or proteins can be used here with particular advantage. This includes the connection Tr-Pl etc.
- an additive in the form of an acid, an acidic salt of an acid and / or an acidic carboxylic acid ester b) an additive in the form of a macromolecular, hydrophilic organic compound with internal cavities for complex integration of low-molecular substances, c) an additive in the form of phenolic compounds and / or d) an additive in the form of a complexing agent for low molecular weight substances.
- These groups of compounds include: Group a): acidic citric acid esters (these compounds also act as plasticizers for cellulose acetate at the same time and can therefore also be used via the Plasticizer dosage, preferably in a mixture with other plasticizers, can be applied without problems), suberic acid, acidic maleic acid, fumaric acid and / or adipic acid esters, in particular in the form of the alkyl acid esters, among which the methyl and ethyl esters are preferred, b) an additive in the form of poly - And / or oligosaccharides, in particular in the form of activated celluloses and starch derivatives and / or cyclodextrin, the ß-cyclodextrin being particularly preferred, and in the form of a native protein, in particular in the form of ß-lactoglobulin, c) an additive in the form of Ellagic acid and / or lignin, and d) an additive in the form of a metal complex of porphy
- the filter cigarettes according to the invention can be produced using conventional methods.
- the additive to the filter made from a fibrous filter material, in particular in the form of cellulose acetate, mixed with a plasticizer, in particular in the form of glycerol triacetate, in a conventional one
- Filtration concept allows the required effects to be achieved with a minimal amount of additive material.
- optimization is possible when additives are out the selected defined substance groups can be selected in order to improve the filter effect.
- This advantage is borne by the knowledge that a special target group of mutagenic substances has to be filtered selectively.
- the effects demonstrated in the Ames test can be fully verified in cell cultures of higher organisms, such as the hamster cell test of cell culture V79. This impressively underlines the relevance of the present invention with regard to the question of smoking and health.
- An advantage of the invention, which should not be underestimated, is that a particularly suitable method for the industrial manufacture of the filter is specified which can be implemented without substantial modification of the existing technologies.
- SK and HK refer to the crimp index which are used exclusively by the Filtertow department of RHONE-POULENC.
- the filters were manufactured on a KDF2 filter rod machine with an AF 2 strand part from Körber AG (Hauni-Werke), Hamburg,
- the filter rod dimensions were 7.8 x 120 mm.
- a paper from Julius Glatz, Toiletfabriken, Neidenfels, Federal Republic of Germany with the designation F 796-28 was used as filter wrapping paper.
- the additive was applied in a mixture with triacetin by means of the plasticizer dosage. Diethyl citrate (CDE) (Boehringer Mannheim GmbH, Chemische Fabrik, Mannheim, Federal Republic of Germany, Art. 663502) and lignin (lignin organosolv from Aldrich-Chemie, Steinheim, Federal Republic of Germany, Art. 37,101-7).
- CDE Diethyl citrate
- lignin lignin organosolv from Aldrich-Chemie, Steinheim, Federal Republic of Germany, Art. 37,101-7
- the plasticizer was determined by differential weighing of filter rods with and without plasticizer.
- the additive layer was calculated on the basis of the plasticizer layer and the concentration of the plasticizer in the triacetin.
- Table I contains
- the filter rods were cut to a length of 20 mm, glued to the tobacco rod of a CORESTA monitor cigarette and according to CORESTA recommended method No. 22 and 23 smoked.
- the nicotine determination and the determination of the nicotine retention was carried out according to the methods CORESTA recommended method No. 7 and 9.
- the condensates were determined using the Arnes test (Maron, Dorothy M.
- the extraction of the smoked Cambridge filter and the dilution is carried out as follows: The Cambridge filter is extracted in 50 ml ethanol pA for 60 min with shaking in an Erlenmeyer flask. An aliquot of the solution is removed and its absorbance is determined by UV spectroscopy at a wavelength of
- the example shows that an increase in the amount of additive also leads to an increase in the antimutagenic effect (cf. in particular sample B1, 5-2), but that the amount of additive used in this case compared to the known filters with additives, is very low.
- the values of the measured nicotine retention for the samples labeled B and C are for illustrative purposes only. In particular, for the samples denoted by B it turns out that, in accordance with the teaching of DE-PS 1 300 854, the citric acid diethyl ester significantly increases the nicotine retention.
