Description
- The present invention relates to the use of a tobacco filter for selectively and efficiently eliminating formaldehyde.
- As an adsorbent for filtering a component in a tobacco smoke, a variety of constituent components are proposed. In
JP- B 3 895327WO-A2003/056947 , andEP 1470761 , a cigarette is disclosed that is characterized by containing a tobacco rod and a filter being connected to the tobacco rod and containing compounds of hydrotalcites of 48.3 to 146.7 mg.
GB-A-1 481 680 - An object of the present invention is to provide a tobacco filter capable of selectively and efficiently eliminating aldehydes (in particular, formaldehyde) and provide tobacco provided with the tobacco filter.
- The present invention provides the use of magnesium aluminometasilicate having a specific surface area in the range of 100 m2/g to 300 m2/g and wherein the pH of a 4% by mass slurry of the magnesium aluminometasilicate is from 8.5 to 10, in a tobacco filter, which comprises the magnesium aluminometasilicate in an amount of 0.5 to 95 % by mass, for selectively absorbing formaldehyde from the mainstream smoke of tobacco.
-
Fig. 1 is an illustrative drawing of a testing method for confirming an adsorption effect of formaldehyde. - In
Fig. 1 , thenumeral reference 1 represents tobacco, 2 represents filter, 3 represents cut surface, 4 represents sealing tape, 5 represents magnesium aluminometasilicate layer, 6 represents glass tube, and 7 represents sealing tape. - A tobacco filter of the present invention is excellent in a selective adsorption property for aldehydes, in particular for formaldehyde.
- According to the invention, a tobacco filter uses the above magnesium aluminometasilicate in a filter material. As the filter material, filter tow conventionally used in tobacco filters, non-woven fabrics or the like can be used.
- The magnesium aluminometasilicate used in the present invention is a known component used as e.g. an antacid, or a filler.
- Although the particle size of magnesium aluminometasilicate is not limited in particular, the particle size range of 100 µm to 1000 µm is preferred from the perspective of containing magnesium aluminometasilicate in a predetermined ratio in the tobacco filter and enhancing the adsorption effect of aldehydes.
- The specific surface area of the magnesium aluminometasilicate is in the range of 100 m2/g to 300 m2/g from the perspective of enhancing the adsorption effect of aldehydes.
- Further, the pH of a 4% by mass slurry of such magnesium aluminometasilicate is in an alkaline region (from 8.5 to 10).
- In addition, the tobacco filter can also contain known various components blended in tobacco filters such as perfumes.
- The ratio of magnesium aluminometasilicate in the tobacco filter is from 0.5% by mass to 95% by mass of magnesium aluminometasilicate, is preferably from 2% by mass to 85% by mass, and is more preferably from 5% by mass to 70% by mass.
- The tobacco filter, wherein the magnesium aluminometasilicate is used according to the present invention preferably has an either embodiment of:
- 1. (I) the one having a filter divided into two or three or more segments and having a layer containing magnesium aluminometasilicate in one spot or two or more spots between the adjacent segments; or
- 2. (II) the one containing magnesium aluminometasilicate in a dispersed state in the filter.
- In the embodiment of (I), in a case where the filter includes three or more segments, it is also possible to have one segment of a layer containing magnesium aluminometasilicate and the rest of layers containing a perfume and the like.
- The tobacco using the magnesium aluminometasilicate according to the present invention is one provided with the tobacco filter mentioned above, which is effective in reducing formaldehyde in the mainstream smoke of tobacco.
- A tobacco filter shown in
Fig. 1 (b) was produced in a manner described below to test the adsorption effect for aldehydes. - A filter of Peace Lights, trade name, (produced by Japan Tobacco, Inc.) was cut at a position 14 mm away from the end portion to separate it into
filters - After removing the
filter 2a, aglass tube 6 was fitted onto theremaining filter 2b to fill a predetermined amount of magnesium aluminometasilicate 5 (trade name Neusilin; Fuji Chemical Industry Co., Ltd.). The types and properties of magnesium aluminometasilicate used in each Example are shown in Table 1. - The magnesium aluminometasilicate was treated with sieves having openings (JIS Z8801-1 2006) of 1.0 mm and 0.1 mm, respectively, to obtain that having a particle size of passing through the openings of 1.0 mm, but not passing through the openings of 0.1 mm. The filter was filled with the magnesium aluminometasilicate.
- After that, the
filter 2a was fitted into theglass tube 6 so as to sandwich themagnesium aluminometasilicate 5 with thefilter 2b. - After that, resultant item was tightly sealed with a
sealing tape 7 so as to completely cover contact surfaces of theglass tube 6 and thefilters Fig. 1 (a) is tobacco as a control, in which a filter was cut in the same manner as inFig. 1(b) to makefilters sealing tape 4 so as to completely cover cut surfaces. - Through the use of the tobacco for testing shown in
Figs. 1(a), (b) , measurement was carried out in a method described below by using a measuring device shown in Fig. 2 ofJP-B 3895327 - Through the use of the tobacco for testing (
Fig. 1b ) and the tobacco as the control (Fig. 1a ), smoking was carried out by a constant volume automatic smoking machine of a piston type (RM20/CS manufactured by Borgwaldt KC GmbH) under the conditions of a flow rate of 17.5 ml/second, a smoking time period of 2 seconds/time, and a smoking frequency of 1 time/minute. Formaldehyde in the mainstream smoke was collected in a DNPH (dinitrophenylhydrazine) solution and was derivatized with the DNPH, and then was measured by using a gas chromatograph (G-3000 manufactured by Hitachi, Ltd.) using the UV (ultraviolet) absorbance. -
- A smaller retention rate of formaldehyde shows a more excellent adsorption performance for formaldehyde. Other aldehydes were also evaluated in a method similar to the above.
