Definitions

the present invention relates to a tobacco filter capable of selectively and efficiently eliminating aldehydes (in particular, formaldehyde) and to tobacco provided with the tobacco filter.
aldehydes in particular, formaldehyde
JP-B 3 895327 equivalent to WO-A2003/056947 , 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.
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.
aldehydes in particular, formaldehyde
the present invention provides a tobacco filter containing magnesium aluminometasilicate of 0.5 to 95 % by mass and tobacco having the tobacco filter or a tobacco product having the tobacco filter or a cigarette having the tobacco filter or a filter product.
the numeral reference 1 represents tobacco
2 represents filter
3 represents cut surface
4 represents sealing tape
5 represents magnesium aluminometasilicate layer
6 represents glass tube
7 represents sealing tape.
a tobacco filter of the present invention is excellent in a selective adsorption property for aldehydes, in particular for formaldehyde.
a tobacco filter of the present invention contains magnesium aluminometasilicate in a filter material.
filter material filter tow conventionally used in tobacco filters, non-woven fabrics or the like can be used.
Magnesium aluminometasilicate used in the present invention is a known component used as an antacid, a filler, and the like.
the particle size of magnesium aluminometasilicate is not limited in particular, the particle size range of 100 ⁇ m to 1000 ⁇ m is preferred from the perspective of containing magnesium aluminometasilicate in a predetermined ratio in the tobacco filter and enhancing the adsorption effect of aldehydes.
magnesium aluminometasilicate is not limited in particular, the range of 100 m 2 /g to 300 m 2 /g is preferred from the perspective of enhancing the adsorption effect of aldehydes.
the pH of a 4% by mass slurry of such magnesium aluminometasilicate is in an alkaline region (from 8.5 to 10), the pH may also be in a neutral region (from 6 to 8).
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 filter 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 of the present invention is one provided with the tobacco filter mentioned above, which is effective in reducing aldehydes 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 2a and 2b.
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.
the filter 2a was fitted into the glass tube 6 so as to sandwich the magnesium aluminometasilicate 5 with the filter 2b.
Fig. 1 (a) is tobacco as a control, in which a filter was cut in the same manner as in Fig. 1(b) to make filters 2a and 2b and then they were tightly sealed with a sealing tape 4 so as to completely cover cut surfaces.
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.
DNPH dinitrophenylhydrazine
a formaldehyde retention rate was calculated by the following equation.
Formaldehyde Retention Rate % 100 ⁇ Cf / Tf
