BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a tobacco odor deodorizing composition, a tobacco odor deodorizer, a cigarette low in sidestream smoke odor, and a tobacco package.
2. Description of the Related Art
In general, tobacco odor such as sidestream smoke released from a tobacco smoking article such as a cigarette is not desirable to, particularly, the nonsmoker. Particularly, it is a matter of serious concern to suppress the odor of the sidestream smoke released to the surroundings during the smoking.
One of the measures for suppressing the odor of the tobacco sidestream is to deodorize the tobacco sidestream smoke released during the smoking from the tobacco smoking article to the surroundings, such as within a room. In general, in order to deodorize the malodor released to the surroundings, a method is employed in which a substance producing a very strong aroma is used as a deodorant, whose strong aroma is mixed with the malodor to shield the malodor (see “Known-Customary Technologies (Perfume), Part I, Perfume In General, Published on Jan. 29, 1999”).
However, in the conventional deodorant, used is a perfume having an intensity higher than that of the smell, with the result that the intensity of the odor after the mixing of the perfume is considerably higher than that before the mixing, resulting in production of an unpleasant feel in many cases. Also, even if it is possible to shield the smell felt before the mixing with the perfume, the odor after the mixing newly produces in many cases another unpleasant feel. It follows that the conventional deodorant fails to basically improve the unpleasantness of the odor.
Another measure for suppressing the odor of the tobacco sidestream smoke is to add a perfume for masking the odor of the sidestream smoke to the tobacco smoking article so as to prevent the odor of the sidestream smoke from being released from the tobacco smoking article itself. For example, in order to improve the odor of the tobacco sidestream smoke released to the surroundings during the static burn of a cigarette, it is proposed to add a perfume for masking the unpleasant odor to the wrapper paper sheet of the cigarette.
However, it has been found that the conventional perfume for masking the odor of the sidestream smoke, which certainly lowers the odor of the tobacco sidestream smoke, also lowers the tobacco aroma tasted as the tobacco mainstream smoke. It has also been found that the fragrance of the perfume itself is produced relatively strongly, with the result that the intensity of the overall odor generated during the static burn of a cigarette is increased.
Under the circumstances, an object of the present invention is to provide a tobacco odor deodorizing composition and a tobacco odor deodorant, which permits masking the tobacco odor without increasing the overall odor after the mixing with the odor of the sidestream smoke released to the surroundings during the smoking to an unpleasant level and without newly producing another unpleasant odor after the mixing with the odor of the sidestream smoke.
Another object of the present invention is to provide a cigarette which permits preventing the intensity of the overall odor generated during the static burn of the cigarette from being significantly increased and which also permits suppressing the odor of the sidestream smoke.
BRIEF SUMMARY OF THE INVENTION
As a result of extensive research conducted in an effort to achieve the objects described above, the present inventors have found that a mandarin orange essential oil fraction having terpene hydrocarbons substantially removed therefrom is effective for eliminating the tobacco odor, and that a mixture containing at least two components of five component groups selected from the constituting components of the essential oil fraction noted above is capable of masking the tobacco odor without increasing the intensity of the overall odor after the mixing of the fragrance of the mixture with the odor of the sidestream smoke released to the surroundings during the smoking to an unpleasant level and without causing the odor after the mixing of the fragrance with the odor of the sidestream smoke to generate another new unpleasant odor. It has also been found that a mixture containing at least two components of five component groups selected from the constituting components of the mandarin orange essential oil fraction is capable of reducing the sidestream smoke odor generated from the cigarette itself without significantly increasing the intensity of the overall odor that is generated during the static burn of the cigarette.
To be more specific, according to a first aspect of the present invention, there is provided a tobacco odor deodorizing composition, which contains at least two component groups selected from five component groups (I) to (V) given below:

DETAILED DESCRIPTION OF THE INVENTION
The present invention will now be described in detail.
The tobacco odor deodorizing composition of the present invention contains at least two groups of components selected from five component groups (I) to (V) given below:

    
    
        (I) octanal, nonanal and/or decanal;
        (II) linalool;
        (III) carvone;
        (IV) methyl anthranilate and/or N-methyl anthranilate; and
        (V) sinensal and/or orange peel essential oil sinensal fraction.
    
    


Among the components noted above, linalool may be any of a d-form, an l-form and a racemic form, carvone may be any of an l-form, a d-form and a racemic form, and sinensal may be any of an α-form, a β-form and a mixture thereof. The orange peel essential oil sinensal fraction represents α,β-sinensal (characteristic component), which can be obtained by fractionation of an essential oil (generally called cold pressed oil) collected when cold or at room temperature, or a fraction rich in the α,β-sinensal component. For example, it is possible to use “sinensal 20/10A National” (trade name) available from R.C. Treat Inc. The components constituting the component groups (I) to (V) are called specified components hereinafter in some cases.
The tobacco odor deodorizing perfume composition of the present invention comprises two specified component system to five specified component system given below under the conditions that, where at least two of components (a) to (c) of component group (I) are contained in the form of a mixture, the mixture is regarded as a single component, that, where components (a) and (b) of component group (IV) are contained in the form of a mixture, the mixture is regarded as a single component, and that, where components (a) and (b) of component group (V) are contained in the form of a mixture, the mixture is regarded as a single component. This is also the case with the present invention.
<Two Specified Component System>
A combination of (I)(a), (I)(b) and/or (I)(c) with (II), (III), (IV)(a) and/or (IV)(b) or (V)(a) and/or (V)(b);

A combination of (I)(a), (I)(b) and/or (I)(c) with (II) and with (III), (IV)(a) and/or (IV)(b) or (V)(a) and/or (V)(b);

    
    
        A combination of (I)(a), (I)(b) and/or (I)(c) with (III) and with (IV)(a) and/or (IV)(b) or (V)(a) and/or (V)(b);
        A combination of (II) with (III) and with (IV)(a) and/or (IV)(b) or (V)(a) and/or (V)(b); or
        A combination of (I)(a), (I)(b) and/or (I)(c), (II) and/or (III) with (IV)(a) and/or (IV)(b) and with (V)(a) and/or (V)(b).
    
    


<Four Specified Component System>
A combination of (I)(a), (I)(b) and/or (I)(c) with (II) and with (III) and with (IV)(a) and/or (IV)(b) or (V)(a) and/or (V)(b);

    
    
        A combination of (II) with (III) and with (IV)(a) and/or (IV)(b), and with (V)(a) and/or (V)(b); or
        A combination of (I)(a), (I)(b) and/or (I)(c) with (II) and/or (III) and with (IV)(a) and/or (IV)(b), and with (V)(a) and/or (V)(b).
    
    


(Five Specified Component System)
A combination of (I)(a), (I)(b) and/or (I)(c) with (II) and with (III), and with (IV)(a) and/or (IV)(b), and with (V)(a) and/or (V)(b).
However, in a preferred embodiment of the present invention, the deodorizing composition of the present invention comprises at least two components, preferably at least three components, selected from the group consisting of octanal, linalool, carvone, methyl anthranilate and an orange peel essential oil sinensal fraction.
The desired effect produced by the deodorizing composition of the present invention is rendered more prominent with increase in the number of specified components. To be more specific, the three specified component system is more desirable than the two specified component system, and the four specified component system is more desirable than the three specified component system. The five specified component system provides the most desirable deodorizing composition of the present invention.
In the deodorizing composition of the present invention, the five specified components are mixed desirably at a weight ratio of (I):(II):(III): (IV):(V)=2-6:3-10:0.5-2.5:0.5-20:0.1-3. It should be noted that the weight ratio given above is applied as it is in respect of the weight ratio of the two specified components in the two specified component system, in respect of the weight ratio of the three specified components in the three specified component system, and in respect of the weight ratio of the four specified components in the four specified component system. This is also the case with the ratio of the specified components. Namely, if the weight ratio of (I):(II):(III):(IV):(V) given above is represented by A:B:C:D:E for the sake of brevity, the ratio of, for example, (II) to (III) in the two component system of (II) and (III) should desirably be B:C, and the ratio of (I) to (IV) in the two component system of (I) and (IV) should desirably be A:D. Likewise, the ratio of (I):(II):(III) in the three component system of (I), (II) and (III) should desirably be A:B:C, and the ratio of (II): (IV):(V) in the three component system of (II), (IV) and (V) should desirably be B:D:E. Also, the ratio of, for example, (I):(II):(III):(IV) in the four component system of (I), (II), (III) and (IV) should desirably be A:B:C:D, and the ratio of (II): (III):(IV):(V) in the four component system of (II), (III), (IV) and (V) should desirably be B:C: D:E.
In the deodorizing composition of the present invention, it is particularly desirable for the components of the composition to be mixed at a weight ratio that permits substantially maintaining the ratio of presence of the specified components in a mandarin orange essential oil. Incidentally, of the specified components (V), the orange peel essential oil sinensal fraction (V)(b) is not contained as it is in the mandarin orange essential oil. However, since the component (V)(b) is equivalent to the component (V)(a) sinensal, the ratio of presence of component (V) is equal to the ratio of presence of sinensal in the mandarin orange essential oil. In other words, the particularly desirable weight ratio of the specified components (I):(II):(III):(IV):(V) in the deodorizing composition of the present invention is 3-5:7-10:1.0-2.0:1.0-3.0:0.5-1.5.
It is possible for the deodorizing composition of the present invention to contain components other than the specified components described above. The other components, which are used preferably in the deodorizing composition of the present invention, include, for example, the mandarin orange essential oil components other than the specified components described above. To be more specific, the other mandarin orange essential oil components, which can be contained in the deodorizing composition of the present invention, include, for example, alcohol components such as 4-terpineol, α-terpineol, octanol, thymol, heptanol, cis-carveol, perillaalcohol, p-menthane 1,8-diol; aldehyde components such as geranial, citronellal and dodecanal; and limonene oxide. The deodorizing composition of the present invention preferably contains the specified components in total in an amount of at least 0.1 mass %, preferably at least 5 mass %, and most preferably at least 30 mass %.
It is possible to house the tobacco odor deodorizing composition of the present invention in a suitable container and to dispose the container as a tobacco deodorant within a room.
However, it is possible for the tobacco odor deodorizing composition of the present invention to be carried by a suitable carrier so as to provide a tobacco odor deodorant.
In this case, it is possible to add further perfume components generally used as a component producing a deodorizing effect to the tobacco odor deodorizing composition of the present invention. The deodorizing perfumes used in the present invention include, for example, various synthetic perfumes, natural perfumes, synthetic essential oils, natural essential oils and a citrus oil. To be more specific, it is possible to use a wide range of deodorizing perfumes described in, for example, “Known Customary Technologies (Perfume), Part I, Perfumes in general, 2•6•16 Masking Agent pp 230-250 (1999)”.
The forms of the tobacco odor deodorant of the present invention includes a liquid, a solid, a powder, a gel, a mist, or an aerosol.
On the other hand, the carrier may be a liquid base material, a solid base material, a powdery base material, a gel base material, a mist base material or an aerosol base material as the carrier in accordance with the selected form of deodorant.
In the present invention, the methods whereby the deodorizing composition is carried by the carrier include, in the case of a liquid base material, a gel base material or a mist base material, using, for example, a surfactant, a gelling agent or a water-soluble high molecular weight material as the carrier, and allowing the deodorizing composition to be carried within the micell or gel formed by the carrier. On the other hand, in the case of a solid base material, a powdery base material or an aerosol base material, the deodorizing composition may be carried on the surface of the powdery or granular formed material such as silica gel.
The liquid base material used in the present invention includes, for example, nonionic surfactants such as polyoxyethylene sorbitan mono-oleate, polyoxyethylene sorbitan monostearate, and polyoxyethylene cured castor oil; and anionic surfactants such as polyoxy lauryl ether sodium phosphate.
The gel base materials include those formed from, for example, gel materials extracted from various plants, animals, algae, and microorganisms such as carrageenan, juran gum, tragacanth, agar-agar, gelatin, and pectin; metal soaps used as gel materials such as sodium stearate and sodium 12-hydroxystearate; and water-soluble organic high molecular weight materials such as polyvinyl alcohol, a cellulose derivative, and a starch derivative.
The solid base materials include, for example, powdery or granular formed materials such as silica gel, alumina, zeolite, diatomaceous earth, calcium silicate, pulp, and cellulose.
The mist base materials include, for example, nonionic surfactants such as polyoxyethylene sorbitan monooleate, polyoxyethylene sorbitan monostearate, and polyoxyethylene cured castor oil; and anionic surfactants such as sodium polyoxylauryletherphosphate.
Further, the aerosol base materials used in the present invention include, for example, spherical formed materials such as a spherical silica gel.
In the present invention, the amount of the tobacco odor deodorant such as the liquid deodorant, the solid deodorant, the powdery deodorant, the gel deodorant, the mist deodorant or the aerosol deodorant is controlled optionally in accordance with the expected effect and function of the deodorant. However, it is generally desirable for the deodorant to contain about 0.005 to 50 mass % of the tobacco odor deodorizing composition.
In putting the tobacco odor deodorant of the present invention to practical use, it is possible to add the deodorant to the perfumes and cosmetics, the foods, the external remedies, the compositions for the oral cavity, or the sanitary materials.
The perfumes and cosmetics include, for example, an emollient lotion, an astringent lotion, a wiping lotion, a milk lotion, a body lotion, an after-shave lotion, a massage cream, a cleansing cream or gel, an antiperspirant, an eye pack agent, shampoos, hair creams, hair tonics, pomades, rinses, conditioners, hair-growing lotions and other cosmetic base materials for the hair; toilet powders, a lipstick, and other cosmetic base materials and detergents for cosmetics.
The foods include, for example, drinking beverage such as a fruit juice beverage, fruit liquors, a milk, a carbonic beverage, and drinks; cold confectionery such as ice creams, sherbets, and ice candies; favorite foods and drinks such as Japanese and Western confectionery, jams, candies, jellies, gums, breads, coffees, cocoas, black teas, oolong teas, and green teas; soups such as Japanese style soup, Western style soup, and Chinese style soup; flavors, seasonings, various precooked drinks and foods, and various snack foods.
The external remedies include, for example, an aerosol preparation, a cataplasm agent, an ointment, and a bathing agent.
The oral compositions includes, for example, a dentifrice, an oral detergent, a mouth wash, and a chewing gum.
Further, the sanitary materials include, for example, washing detergents, detergent for disinfection, detergents for odor prevention, indoor fragrance producing agents, indoor deodorants, soaps, detergents for washing dishes, softeners, furniture cares, and other sanitary detergents; various sanitary materials such as tissue paper, and toilet paper; and sanitary medicines such as a flavor imparting agent for facilitating the dosage of a medicine.
It suffices for the tobacco odor deodorant of the present invention to contain as indispensable ingredients the 2 or more, preferably 3 or more specified components noted above, and a carrier carrying these components. Where the deodorant of the present invention is applied to perfumes, cosmetics, foods, external remedies, oral compositions, or sanitary materials, it is possible to apply the deodorant directly or in the form of a solution having the deodorant dissolved in, for example, alcohols, or polyhydric alcohols such as propylene glycol, or glycerin; in the form of an emulsion emulsified by using an emulsifying agent such as natural rubbery materials including gum arabic and tragacanth, glycerin fatty acid ester, or a sucrose fatty acid ester; in the form of a powder prepared by using an excipient such as natural gum substance including gum arabic, gelatin, or dextrin; in the form of a soluble or dispersible material that is made soluble or dispersible by using a surfactant such as a nonionic surfactant, an anionic surfactant, a cationic surfactant or an amphoteric surfactant; or in the form of a microcapsule prepared by the processing with an encapsulizing agent. The form of the deodorant can be selected appropriately in accordance with the object of applying the deodorant.
Further, it is possible to have the tobacco odor deodorant of the present invention included in an inclusion agent such as cyclodextrin so as to stabilize and to release gradually the deodorant. These are selected for use appropriately in a manner to be adapted for the form of the final product of the deodorant such as a liquid form, a solid form, a powdery form, a gel form, a mist form or an aerosol form.
Also, the tobacco odor deodorant of the present invention is used in some cases in combination with other deodorants such as a perfume, an oxidizing agent, a reducing agent, a neutralizing agent, an inorganic deodorant such as an inorganic base, an inorganic acid, a metal oxide, a chlorine compound, ozone, and a porous material, and surfactants such as a nonionic surfactant, an anionic surfactant, a cationic surfactant and amphoteric surfactant.
Incidentally, the addition amount of the tobacco odor deodorant to the final products such as the perfumes and cosmetics, the foods, the external remedies, the oral composition, and the sanitary material can be determined optionally in accordance with the expected effect and function, though about 0.0005 to 20 mass % of the tobacco odor deodorant is added in general based on the total mass of the final product.
Further, the tobacco odor deodorizing composition of the present invention can provide a tobacco sidestream smoke odor reducing agent for reducing the tobacco sidestream smoke odor generated from the cigarette itself.
The sidestream smoke odor reducing agent of the present invention is carried by a cigarette. The cigarette comprises a tobacco rod including a tobacco filler material and a cigarette wrapper paper sheet wrapping the outer circumferential surface of the tobacco filler material. The tobacco filler material includes tobacco shreds. The tobacco shreds may be expanded. It is possible to employ a known expanding method for expanding the tobacco shreds. Also, it is possible to use any wrapper paper sheet suitable for wrapping the outer circumferential surface of the tobacco filler material so as to provide a cigarette. Incidentally, the cigarette of the present invention may be provided with a filter plug at one end of the tobacco rod.
The sidestream smoke odor reducing agent of the present invention can be carried by the cigarette in various forms. For example, the sidestream smoke odor reducing agent of the present invention can be carried by the cigarette by adding the odor reducing agent to the tobacco filler material, by coating the cigarette wrapper paper sheet with the odor reducing agent, or by adding the odor reducing agent to a seam paste for bonding the cigarette wrapper paper sheet. The effect of reducing the sidestream smoke odor is not particularly dependent on the application positions such as the tobacco shreds. However, it is possible to add the sidestream smoke odor reducing agent of the present invention to the tobacco filler material by the ordinary technology of imparting flavor to the tobacco shreds. Naturally, the particular addition method is convenient. In any case, it is desirable for the sidestream smoke odor reducing agent of the present invention to be applied uniformly. Incidentally, where the cigarette of the present invention has a filter plug at one end of the tobacco rod, the filter plug is connected in general to the tobacco rod by using a so-called tip paper. It is possible to coat the tip paper or a filter wrapper paper sheet with the sidestream smoke odor reducing agent of the present invention.
The sidestream smoke odor reducing agent of the present invention is carried by the cigarette of the present invention such that the total amount of the specified components amount to preferably at least 0.01 mg per cigarette, more preferably, 0.02 mg to 0.2 mg per cigarette.
Further, the sidestream smoke odor reducing agent of the present invention can be housed in a tobacco package. The tobacco package contains a plurality of cigarettes, e.g., 20 cigarettes, each comprising a tobacco rod including a tobacco filler material and a cigarette wrapper paper sheet wrapping the outer circumferential surface of the tobacco filler material as well as the sidestream smoke odor reducing agent of the present invention. The sidestream smoke odor reducing agent of the present invention can be housed in the tobacco package by, for example, applying it to an aluminum foil. The sidestream smoke odor reducing agent of the present invention housed in the tobacco package is migrated into the cigarette before the tobacco package is opened so as to decrease the sidestream smoke odor in the smoking time.
The present invention will now be described by way of its Examples, which do not limit the present invention, and the present invention is not limited to these Examples.
The organoleptic evaluation methods (odor bag method and room method) employed in the following Examples are as follows:
A. Odor Bag Method (Deodorizing Composition):
Prepared are a parallelepiped chamber (sidestream smoke chamber) having an inner volume of 405 L and equipped, at an upper portion of the inside wall, with an air bag mounting tube communicating with the outer atmosphere, and at a lower portion of the inside wall, with a through-hole for insertion of an inner air suction port, and also having a cigarette mounting tool at the inside wall, as well as an air collecting box available on the market. The air collecting box, which has an inner volume slightly larger than 10 L, has an inner air suction port formed in a lower portion of the inside wall and a discharge hole formed in a lower portion of the inside wall facing the inside wall having the air suction port formed therein.
An air bag having an inner volume of 10 L is mounted to the air bag mounting tube of the sidestream smoke chamber, and a collecting bag having an inner volume of 10 L is mounted to the suction port of the air collecting box. Then, the suction port of the air collecting box is inserted into the through-hole of the sidestream smoke chamber. Further, the discharge port of the air collecting box is connected to the air bag mounting tube of the sidestream smoke chamber by using a hose with a vacuum pump interposed therebetween such that it is possible to suck the air inside the air collecting box and to discharge the sucked air into the air bag mounted inside the chamber, establishing a closed system.
Under the condition described above, a cigarette is mounted to the cigarette mounting tool inside the chamber and is subjected to the static burn so as to generate a sidestream smoke.
After the static burn of the cigarette is completed, the vacuum pump is driven so as to establish a negative pressure inside the air collecting box and at the same time to increase the pressure inside the sidestream smoke chamber by the air discharge into the air bag, thereby allowing the air containing the sidestream smoke within the sidestream smoke chamber to be collected in the collecting bag within the collecting box.
The collecting box is detached from the sidestream smoke chamber under the state that the collecting bag collecting the air containing the sidestream smoke is left housed in the collecting box. Then, the collecting box is connected to a diluting line. The diluting line comprises a line for supplying, by using a pump, a deodorized air into an odor bag having an inner volume of 3 L and connected to its downstream terminal and a branched line branched from the line for supplying the deodorized air so as to be connected to the suction port of the collecting box. Each of these lines is provided with a flow rate control valve. The collecting box is pressurized by a pressurizing pump so as to permit the air within the collecting bag to be supplied into the odor bag through the branched line.
The composition to be evaluated is injected by a syringe into the odor bag thus prepared (diluted to have a concentration equal to that in the case of combusting a single cigarette per 17 m3) and evaporated. The odor bag having the perfume composition injected therein is presented in blind to the panelist together with an odor bag not having a perfume injected therein for the evaluation by a paired comparison test (method of compulsory selection between the two). The result of the evaluation is reported by the panelist in terms of the items given below:

    
    
        1. Which bag has a stronger intensity of the overall odor?
        2. Which bag has a good odor?
        3. Which bag has a stronger tobacco odor?
    
    


In each of the evaluation items 1 to 3 given above, the number of panelists selecting the odor bag having the perfume composition injected therein was divided by the number of the entire panelists so as to obtain the result of the evaluation. It follows that the smaller number represents the better result in respect of each of the intensity of the overall odor and the intensity of the tobacco odor. On the other hand, the larger number represents the better result in respect of the quality of the odor. Incidentally, optionally extracted adults who had not received an expert training on the tobacco odor were selected as the panelists
B. Odor Bag Method (Cigarette):
The odor of the sidestream smoke of the cigarette was collected and diluted as in the odor bag method (deodorizing composition) described above. An odor bag in respect of a cigarette for a reference case and another odor bag in respect of a cigarette to be evaluated were presented in blind to five expert panelists for the functional evaluation in five stages ranging between point 0 (no odor) and point 4 (highest point).
C. Room Method
Prepared are two rooms (room A and room B) each having a floor area of 31 m2 and a volume of 85 m3, and each being closed except for a door, through which the evaluators enter or leave the room. With the door closed, five reference cigarettes are subjected to static burn within room A. On the other hand, five cigarettes to be evaluated are subjected to static burn within room B, also with the door closed. The panelists are classified into two groups. All the panelists of one group simultaneously enter room A and, after coming out of room A, enter room B. Then, the panelists coming out of room B report the results in respect of the items given below. On the other hand, all the panelists of the other group simultaneously enter room B and, after coming out of room B, enter room A. Then, the panelists coming out of room A report the results in respect of the items given below:

    
    
        1. In which room did the panelists feel a higher intensity of the overall odor?
        2. In which room did the panelists feel an improvement in the odor?
        3. In which room did the panelists feel a higher intensity of the tobacco odor?
    
    


To obtain the results, the number of panelists who answered, “room B”, in which the cigarettes for evaluation were subjected to the static burn, was divided by the number of all the panelists in respect of each of the evaluation items 1 to 3 given above. It follows that a smaller number represents a better result for both the intensity of the overall odor and the intensity of the tobacco odor. On the other hand, a larger number represents a better result in respect of the improvement of the odor. Incidentally, the panelists were randomized adults, who had not received training on the tobacco odor.

As apparent from the results of evaluation given in Table 43, the cigarettes carrying the sidestream smoke odor reducing agent of the present invention permit improving the odor and lowering the intensity of the tobacco odor without substantially increasing the intensity of the overall odor, compared with the cigarette of the Comparative Example.
Examples 42 to 48
The formulated perfume (sidestream smoke odor reducing agent) prepared in Preparation Example 18 was applied to the applied portions shown in Table 44 given below, not to the tobacco shreds, in the amounts shown in Table 44 so as to obtain a prescribed number of cigarettes. An ethylene-vinyl acetate copolymer was used as the seam paste. The application of the formulated perfume to the wrapper paper sheet was conducted by directly spraying the formulated perfume to the wrapper paper sheet.
Also, a prescribed number of reference cigarettes were prepared in exactly the same procedure, except that the formulated perfume was not added.
The sidestream smoke odor was evaluated by the room method described previously in respect of each of the cigarettes thus prepared. Table 44 also shows the result.
