Description

Filtercigarette Filter cigarette
Die Erfindung betrifft eine Filtercigarette .The invention relates to a filter cigarette.
Der Rauch von Cigaretten setzt sich aus einer Partikel- und einer Gasphase zusammen . Bei vielen herkömmlich verwendeten Filtern wird der Rauch mit Hilfe von Celluloseacetat gefil- tert . Die Gasphase wird dabei oft nicht in zufrieden stellendem Maße abgesenkt, daher werden häufig weitere Konstruktionsmerkmale angepasst . Zum Beispiel ist es üblich, Cigaretten mit einer relativ hohen Ventilation zu versehen, die bewirkt, dass die Gasphase zusätzlich mit Luft verdünnt wird . Eine weitere Möglichkeit der zusätzlichen Gasphasenreduktion ist der Einsatz von gasphasenaktiven, das heißt die Gasphase reduzierenden, Substanzen im Filter . Zur Ermittelung der Gasphasensubstanzen im Cigarettenrauch werden Cigaretten meist nach ISO- Norm abgeraucht . Werden alternative Abrauchbedingungen ge- wählt , wie es z . B . unter Intense-Abrauchbedingungen ( siehe Definitionen weiter unten) in Canada üblich ist, liegen die Gasphasenwerte deutlich höher .The smoke of cigarettes is composed of a particle and a gas phase. In many conventionally used filters, the smoke is filtered with the aid of cellulose acetate. The gas phase is often not lowered to a satisfactory extent, so often other design features are adjusted. For example, it is common to provide cigarettes with a relatively high ventilation, which causes the gas phase to be additionally diluted with air. Another possibility of additional gas phase reduction is the use of gas phase-active, that is reducing the gas phase, substances in the filter. To determine the gas phase substances in cigarette smoke, cigarettes are usually smoked to the ISO standard. If alternative smoking conditions are selected, as is the case for example. B. under intense smoking conditions (see definitions below) in Canada, gas phase values are significantly higher.
Aus dem Stand der Technik sind Filtercigaretten bekannt, die mit Hilfe von gasphasenaktiven Substanzen den Tabakrauch so beeinflussen, dass die Menge der Gasphase im durch den Raucher inhalierten Hauptstromrauch reduziert wird .Filter cigarettes are known from the prior art, which influence the tobacco smoke with the aid of gas-phase-active substances in such a way that the amount of gas phase in the mainstream smoke inhaled by the smoker is reduced.
Zum Beispiel sind Filtercigaretten auf dem Markt, deren Gasphasenwerte durch den Zusatz von gasphasenaktiven Substanzen, wie zum Beispiel Aktivkohle, reduziert sind. Aktivkohlefilter, bei denen die Aktivkohle in eine Kammer eingebracht wird, wer- den seit langem und insbesondere in Japan häufig eingesetzt und sind aus der WO 02/37990 A2 oder aus weiteren Schriften bekannt wie z . B . der DE 42 056 58 Al oder der WO 00/49901 Al .For example, filter cigarettes are on the market whose gas phase values are reduced by the addition of gas phase active substances, such as activated carbon. Activated carbon filters, in which the activated carbon is introduced into a chamber, are used for a long time and especially in Japan and are known from WO 02/37990 A2 or from other documents such. B. DE 42 056 58 A1 or WO 00/49901 A1.
Bei dem Produkt "Advance" besteht der Filter aus einem Filter- segment mit Aktivkohle und einem Filtersegment mit Ionenaustauscherharzen sowie optional einem mundseitigem Filtersegment aus Celluloseacetat . Vergleichbare Cigaretten sind in der WO 03/015544 Al und der WO 2004 /103099 A2 beschrieben .For the "Advance" product, the filter consists of a filter segment with activated charcoal and a filter segment with ion exchange resins and optionally a mouth-side filter segment made of cellulose acetate. Comparable cigarettes are described in WO 03/015544 A1 and WO 2004/103099 A2.
Die Gasphasenreduktion wird zudem beeinflusst von der Kombina- tion der Designparameter einer Filtercigarette , wozu nicht nur die Filteradditive, sondern auch die Beschaffenheit des Tabaks , des Umhüllungsmaterials sowie der Filterkomponenten gehören .The gas phase reduction is also influenced by the combination of the design parameters of a filter cigarette, which includes not only the filter additives, but also the nature of the tobacco, the wrapping material and the filter components.
Allen genannten Vorbenutzungen oder Vorbeschreibungen ist j e- doch gemein, dass bei den beschriebenen Cigaretten die Gasphase nicht in einem zufrieden stellenden Maße abgesenkt wird . Bei marktüblichen Cigaretten liegen die Werte für den Ge- samtgasphasengehalt Gges (siehe unten) über 1200 μg/Cigarette, gemessen nach ISO .Common to all the aforementioned uses or descriptions, however, is that the gas phase is not lowered to a satisfactory extent in the cigarettes described. For commercially available cigarettes, the values for the total gas phase content G ges (see below) are more than 1200 μg / cigarette, measured according to ISO.
Oft wird eine hohe Gasphasenabsenkung nur mit Hilfe einer sehr hohen Ventilation erreicht , was dann bedingt , dass die Gasphasenwerte, wenn diese unter Intense-Abrauchbedingungen ermittelt werden, extrem erhöht sind .Often a high gas phase lowering is achieved only by means of a very high ventilation, which then implies that the gas phase values are extremely increased when they are determined under intense smoking conditions.
Ein weiterer Nachteil besteht darin, dass konventionelle gas- phasenaktive Cigarettenfilter nach einer gewissen Lagerzeit an Effektivität verlieren .A further disadvantage is that conventional gas phase active cigarette filters lose their effectiveness after a certain storage time.
Den Cigaretten nach dem Stand der Technik werden häufig entweder in der Tabakmischung oder im Filter weitere Substanzen zugesetzt, wie zum Beispiel Palladium zum Tabak wie in der WO 02/37990 Al . Nachteilig hierbei sind die hohen Kosten und erschwerte Herstellbedingungen . Nachteilig sind auch aufwendige und teure Multifilterkonstruk- tionen mit einer Vielzahl unterschiedlicher Adsorbenzien oder teurer Spezialmaterialien .The cigarettes according to the prior art are often added further substances either in the tobacco mixture or in the filter, such as palladium to tobacco as in WO 02/37990 Al. The disadvantage here is the high costs and difficult manufacturing conditions. Also disadvantageous are complex and expensive Multifilterkonstruk- tions with a variety of different adsorbents or expensive special materials.
Aufgabe der Erfindung ist es , eine Filtercigarette mit einer signifikanten Gasphasenreduktion des Tabakrauches zu schaffen . Diese Gasphasenreduktion sollte auch unter so genannten Inten- se-Abrauchbedingungen ( siehe unten) gegeben sein . Die Gasphaseneffizienz des Filters sollte möglichst über einen längeren Zeitraum, z . B . den Zeitraum der Lagerung der Cigaretten, kon- stant sein oder sich zumindest nur geringfügig ändern .The object of the invention is to provide a filter cigarette with a significant gas phase reduction of the tobacco smoke. This gas phase reduction should also be given under so-called Intense-Abrauchbedingungen (see below). The gas phase efficiency of the filter should be possible over a longer period, eg.

Noch vorteilhafter ist es , wenn der Gehalt an TSNA im Tabak unterhalb von 1 μg/g Tabak liegt .The tobacco of the tobacco rod preferably consists of an American Blend mixture or a Virginia blend. The tobaccos of the tobacco blend are preferably provided with an additive level below 1% of non-volatiles relative to the tobacco dry substance; most preferably no additives are used. The tobaccos are preferably selected so that the TSNA content (TSNA: tobacco-specific nitrosamines) of the total mixture is less than 2 μg / g tobacco. It is even more advantageous if the content of TSNA in the tobacco is below 1 μg / g of tobacco.
Der Tabak kann Zusatzmittel oder Zusätze wie z . B . Casing, Aromastoffe, Feuchthaltemittel, Zucker, Kakao, Lakritze, Menthol enthalten . Das Cigarettenpapier, das den Tabakstrang umgibt , ist vorzugsweise porös und hat eine Porosität von mehr als 40 CU (Coresta Units ) oder mehr als 60 CU . Zur Erreichung besonders niedriger NFDPM-Werte ( siehe unten) im Bereich von 4-7 mg/Cigarette ist die Porosität vorzugsweise größer als 300 CU . Dazu kann das natürlich poröse Cigarettenpapier zusätzlich elektroperftariert, mechanisch perforiert oder laserperforiert werden .The tobacco may additives or additives such. B. Casing, Flavorings, Humectants, Sugar, Cocoa, Licorice, Menthol included.

The filter ventilation is between 0% and 30% and is preferably between 10% and 25%. In other embodiments, the filter ventilation is in the range of 30% to 70%, preferably in the range of 30% to 60%. For a better understanding of the invention, some terms are explained or defined in more detail below.
Die Gasphase des Cigarettenrauchs ist ein komplexes Stoffgemisch aus Permanentgasen wie z . B . N2 und CO2 sowie einer Viel- zahl von leicht- und mittelflüchtigen Verbindungen . Einige dieser Komponenten werden mit den gesundheitlichen Auswirkungen des Rauchens in Verbindung gebracht . So finden z . B . Formaldehyd, Blausäure und Benzol Erwähnung in den für Deutschland vorgeschriebenen Warntexten auf Cigarettenpackungen .The gas phase of Cigarettenrauchs is a complex mixture of permanent gases such. B. N 2 and CO 2 and a large number of light and medium volatile compounds. Some of these components are associated with the health effects of smoking. To find z. B. Formaldehyde, hydrocyanic acid and benzene Mention in the warning texts prescribed for Germany on cigarette packs.
Durch Einsatz von gasphasenreduzierenden Substanzen (insbesondere Adsorbentien) wie z . B . Aktivkohle lässt sich der Gehalt vieler leicht- und mittelflüchtiger Verbindungen im Rauch reduzieren . Der Gehalt an Permanentgasen, wie z . B . CO, bleibt demgegenüber weitgehend unverändert . Zur Charakterisierung dieses Effekts sollte eine Messgröße gefunden werden, die möglichst unbeeinflusst von anderen Konstruktionsmerkmalen die Effektivität solcher Adsorbentien beschreibt .By using gas phase reducing substances (in particular adsorbents) such. B. Activated carbon can reduce the content of many light and medium volatile compounds in the smoke. The content of permanent gases, such. B. CO, remains largely unchanged. To characterize this effect, a measure was to be found that describes the effectiveness of such adsorbents as unaffected as possible by other design features.
Hierzu wurde im Rahmen einer internen Studie der Einfluss verschiedener Parameter auf die Gasphasenmenge und -zusammen- setzüng untersucht . Es zeigte sich hierbei, dass ein Quotient aus Benzol- und CO-Gehalt im Rauch am besten zur Beschreibung der Adsorption von Gasphasenkomponenten geeignet ist . Dabei wird definitionsgemäß die Einhheit des Benzolgehaltes in μg/Cigarette angegeben und die des CO-Gehaltes in mg/Cigarette . Zum einen wird der Einfluss von Filter- und Strangventilation durch die Normierung auf den CO-Gehalt kompensiert . Zum anderen ist der Benzolgehalt in der Gasphase weitgehend unabhängig von der Tabakmischung, kann aber durch Adsorbentien nachhaltig beeinflusst werden, während CO prak- tisch nicht adsorbiert wird . Dieser Quotient wird für Daten, die unter ISO-Abrauchbedingungen ermittelt wurden, im Folgenden mit Ql bezeichnet . Handelt es sich um Daten, die unter In- tense-Abrauchbedingungen ermittelt wurden, wird der Quotient mit Q2 bezeichnet . Ein niedriger Wert für Ql bzw . Q2 ist also ein Maß für eine hohe Gasphasenreduktion .For this purpose, the influence of various parameters on the gas phase quantity and composition was investigated in an internal study. It was shown that a ratio of benzene and CO content in the smoke is best suited to describe the adsorption of gas phase components. By definition, the unity of the benzene content in μg / cigarette and that of the CO content in mg / cigarette. On the one hand, the influence of filter and line ventilation is compensated by normalization for the CO content. On the other hand, the benzene content in the gas phase is largely independent of the tobacco mixture, but can be sustainably influenced by adsorbents, while CO is virtually not adsorbed. This quotient is referred to below as Ql for data determined under ISO smoking conditions. In the case of data determined under Intense smoking conditions, the quotient becomes labeled Q2. A low value for Ql resp. Q2 is therefore a measure of a high gas phase reduction.
Ein weiterer Vorteil ist darin zu sehen, dass die Bestimmung von CO im Cigarettenrauch durch internationale Normen beschrieben ist . Benzol wird als Bestandteil der so genannten "Hoffman Analytes" ebenfalls häufig im Rauch bestimmt . Weitere Angaben hierzu finden sich z . B . in M. E . Counts et al . J. Regu- latory Toxicology and Pharmacology 39 (2004 ) , 111-134.Another advantage is that the determination of CO in cigarette smoke is described by international standards. Benzene is also often detected in smoke as part of the so-called "Hoffman Analytes". Further information can be found z. B. in M.E. Counts et al. J. Regulatory Toxicology and Pharmacology 39 (2004), 111-134.
An gleicher Stelle finden sich Daten für Benzol und CO für eine Auswahl von Cigarettenmarken aus unterschiedlichen Ländern, von denen eine Auswahl in der Tabelle 1 wiedergegeben ist . Die Bestimmung des Filtertyps erfolgte durch eigene Untersuchungen. Es zeigt sich, dass für eine breite Spanne von Produkten mit konventionellem Filter aus Celluloseacetat (CA) der Quotient mit 3 , 5 bis 5 , 5 relativ konstant ist . Für Produkte mit Aktivkohlefilter (AK) finden sich dagegen niedrigere Werte zwischen 1 , 8 und 3 , 0.At the same place are data for benzene and CO for a selection of cigarette brands from different countries, a selection of which is given in Table 1. The determination of the filter type was made by own investigations. It can be seen that for a wide range of products with conventional filter of cellulose acetate (CA) the quotient with 3, 5 to 5, 5 is relatively constant. For products with activated carbon filter (AK), however, there are lower values between 1, 8 and 3, 0.
Tabelle 1Table 1
Erfindungsgemäß wird die Gasphase spezifisch dahin gehend be- einflusst, dass das Verhältnis Qi unterhalb der bei handelsüblichen Cigaretten gemessenen Werte liegt, und zwar unter 1 , 5 , gemessen nach ISO-Abrauchbedingungen .

According to the invention, the gas phase is specifically influenced such that the ratio Qi is below the values measured for commercial cigarettes, namely below 1.5, measured according to ISO smoking conditions. Q2 is preferably below 3, measured after intense smoking conditions.

Es wurden 20 Cigaretten gemäß ISO 3308 abgeraucht, das Feuchtkondensat auf dem Glasfaserfilter abgeschieden und die Gasphase zur Pumpe der Rauchmaschine geleitet . Mittels eines Probenahmeventil wurden definierte Züge von unterschiedlichen Cigaretten für die anschließende Analyse genommen und in einem Kolbenprober aus Glas gesammelt . Unmittelbar nach dem Abrauchen wurden 6 ml der Gasprobe mit einer Probenschleife in den Inj ektor eines Gaschromatographen (GC) überführt , aufgetrennt und mittels FID detektiert .

The test cigarettes were previously conditioned in accordance with ISO 3402. 20 cigarettes were smoked according to ISO 3308, the wet condensate was deposited on the glass fiber filter and the gas phase was passed to the smoke machine pump. By means of a sampling valve, defined traits were taken from different cigarettes for the subsequent analysis and collected in a glass jar. Immediately after fumigation, 6 ml of the gas sample were transferred to the injector of a gas chromatograph (GC) with a sample loop, separated and detected by FID.

Die Versuchscigaretten nach Beispiel 1 und 2 wurden sowohl unter ISO-, als auch Intense-Abrauchbedingungen abgeraucht und die Cytotoxizität der Gasphase gemäß NRU und MTS-Tests ermittelt .The test cigarettes of Examples 1 and 2 were smoked under both ISO and intense smoking conditions and the cytotoxicity of the gas phase was determined according to NRU and MTS tests.
Es wurden EC50-Werte der Gasphasen ermittelt . Die Werte der Toxizität werden angegeben in Prozent Abnahme der ' Toxizität bezogen auf eine handelsübliche Vergleichscigarette mit vergleichbaren NFDPM-Werten und vergleichbaren Tabakmischungen . Aus der Tabelle ist ersichtlich, dass bei allen untersuchten Proben die Cytotoxizität der Versuchscigaretten deutlich nied- riger liegt als bei den dazugehörigen Vergleichscigaretten . Die Cigaretten wurden nach ISO-Bedingungen abgeraucht und die Gasphase untersucht . Die Cigaretten wurden außerdem nach In- tense-Bedingungen abgeraucht und die Gasphase untersucht . Unter beiden Abrauchbedingungen war die Cytotoxizität bei den erfindungsgemäßen Cigaretten deutlich niedriger als bei dem Vergleich .EC50 values of the gas phases were determined. The toxicity values are given in percent decrease in the toxicity relative to a commercially available comparison cigarette with comparable NFDPM values and comparable tobacco mixtures. It can be seen from the table that the cytotoxicity of the test cigarettes is significantly lower for all samples tested than for the corresponding comparison cigarettes. The cigarettes were smoked according to ISO conditions and the gas phase was examined. The cigarettes were also smoked after inert conditions and the gas phase was examined. Under both smoking conditions, the cytotoxicity was significantly lower in the cigarettes according to the invention than in the comparison.
Tabelle 6Table 6
Beispiel 6 Example 6
Für die Version in Beispiel β wurde eine American-Blend- Tabakmischung ebenfalls gänzlich ohne Zusatzmittel hergestellt . Als Vergleich wurde eine handelsübliche ültra- Cigarettenmarke untersucht .For the version in Example β, an American Blend tobacco blend was also made entirely without any additive. As a comparison, a commercially available ültra-Cigarettenmarke was examined.
Die einzelnen Ergebnisse beider Cigaretten sind in Tabelle 7 zusammengestellt .The individual results of both cigarettes are summarized in Table 7.
Der Filter bestand aus einem Filterabschnitt aus reinem Cellu- loseacetat und einem strangseitigem 15 mm langen Abschnitt aus Celluloseacetat, in das pro mm 5 mg Aktivkohle eingebracht wurden, so dass der Filter insgesamt 75 mg Aktivkohle enthielt .The filter consisted of a pure cellulose acetate filter section and a 15 mm long strand section of cellulose acetate, into which 5 mg of activated charcoal were introduced per mm, so that the filter contained a total of 75 mg of activated charcoal.
Das Cigarettenpapier der erfindungsgemäßen Cigarette besaß eine Porosität von 50 CU und ein Flächengewicht von 22 g/m2.The cigarette paper of the cigarette according to the invention had a porosity of 50 CU and a basis weight of 22 g / m 2 .
Der Glimmsalzgehalt betrug für diese Version 1 , 3 % Natrium-/ Kaliumeitrat .The mulled salt content for this version was 1.3% sodium / potassium citrate.
Der Filter war von einem Filterumhüllungspapier umgeben . Der Tabakstrang wurde mit dem Filter durch ein Umwickelpapier verbunden .The filter was surrounded by a filter wrap paper. The tobacco rod was connected to the filter by a wrapping paper.
An einer online-Lasereinrichtung wurde eine Filterventilation von 60 % eingestellt .On an online laser device, a filter ventilation of 60% was set.
Diese Auswahl der Designparameter ergab die gewünschte Reduktion der Gasphasewerte sowohl unter ISO- wie auch unter Inten- se-Abrauchbedingungen (CINT) .This selection of design parameters yielded the desired reduction in gas phase values under both ISO and Intense Crying Conditions (CINT).
Ebenso konnten dadurch die Quotienten Ql und Q2 deutlich reduziert werden. Tabelle 7Likewise, the quotients Q1 and Q2 could be significantly reduced. Table 7
