Description

  The present invention relates to a scented tissue paper that emits a scent and a method for producing the tissue paper.

  Some tissue papers are designed to emit a scent. This scented tissue paper has many high-value-added tissue paper containing a moisturizer, also called a lotion chemical, to give it a more luxurious feeling, for example, mint-based to give a refreshing feeling, There are those with a mint flavor and those with a citrus flavor that gives a sweet impression.

  In such a scented tissue paper, the fragrance is not directly applied to the tissue paper so that it can be stably scented until the user uses the tissue paper after it is manufactured. A fragrance is encapsulated in microcapsules and dispersed in a moisturizing liquid so as to be applied. By encapsulating the fragrance in the microcapsule in this way, the microcapsule is broken due to sliding of the tissue paper and the storage box when taking out the tissue paper from the storage box, and a fragrance is emitted, and during the storage period In addition, the fragrance is stably and continuously emitted until the user uses up the tissue paper without any transpiration.

  However, this conventional tissue paper with a fragrance has a poor yield when a fragrance is encapsulated in a microcapsule. In addition, since the microcapsules are expensive, there is a problem that the product cost increases. In addition, the outer shell of the microcapsule is a resin material such as melamine resin, urea resin, or urethane resin. When such a resin material bites a runny nose or wipes the mouth, it is not intended. There is also a problem that there is a risk of being taken in.

  As described above, the conventional scented tissue paper has a problem that the production is complicated and the cost is high, and further safety is required.

  Then, the main subject of this invention is providing the scented tissue paper which is excellent in smoothness and softness, is easy to manufacture and low in cost, and safer than the conventional one, and a method for manufacturing the same.

The present invention that has solved the above problems is as follows.
[Invention of Claim 1]
A tissue paper of 2 plies or more, which includes cyclodextrin which is an inclusion body in which at least a part of the perfume is included, and a moisturizing agent, and the content of the moisturizing agent per ply is 1.0 to It was 5.0 g / m ^2, 1 basis weight per ply is 10 to 20 g / m ^2, the moisture content is 5-15 wt%, scented tissue paper, characterized in that.

[Invention of Claim 4]
A scent characterized by mixing cyclodextrin, which is at least partly clathrate containing a fragrance, with a humectant having a water content of 10% by weight or less and applying it to tissue paper. A method for manufacturing tissue paper.

[Invention of Claim 5]
The method for producing tissue paper according to claim 4, wherein cyclodextrin, which is at least partly clathrate containing a fragrance, is mixed with a moisturizing agent and then applied to the tissue paper within 12 hours. .

[Invention of Claim 6]
The method for producing a scented tissue paper according to claim 4 or 5, wherein the fragrance content relative to cyclodextrin is 3 to 20% by weight.

(Function and effect)
The tissue paper with a fragrance of the present invention has a cup-shaped cyclic structure, and includes a cyclodextrin having a property of including a hydrophobic molecule as a guest molecule inside, and including the guest molecule as a fragrance component The body was included. Since cyclodextrin releases the guest molecules included in the presence of moisture, the scented tissue paper of the present invention emits a faint scent when the tissue paper absorbs moisture in the atmosphere, and also produces a runny nose. When it is bitten and absorbs a large amount of water, it will emit a strong scent.

  Cyclodextrin is stable to bases and heat, and relatively stable to acids, has excellent handling properties, is inexpensive, and is used in foods and pharmaceuticals. Compared to a resin material that forms the outer shell of a microcapsule used for tissue paper, the cost is low and the safety is excellent. In addition, the method of inclusion of guest molecules is also high in yield and low in cost, such as an emulsification method and a saturated aqueous solution method. Therefore, the scented tissue paper of the present invention is easier to manufacture and less expensive than the scented tissue paper using conventional microcapsules, and also has high safety.

Moreover, the tissue paper with a fragrance of the present invention has a basis weight per ply of 10 to ²⁰ g / m ² and a moisturizing agent content per ply of 1.0 to 5.0 g / m ² . is there. Within this range, the tissue paper is soft and high-quality. The content of the moisturizing agent per ply is a value obtained by dividing the moisturizing agent contained in the tissue paper made into a set of a plurality of plies by the number of plies.

  Here, the humectant may be either an oily humectant mainly composed of an oily component or an aqueous humectant mainly composed of an aqueous component, but an aqueous humectant is more preferable. Aqueous moisturizers take moisture in the atmosphere due to the hygroscopicity of polyols and the like, and give tissue paper a moist feeling. When using such an aqueous moisturizer, the moisturizing action gives the tissue paper a moist feeling. A perfume component, which is a guest molecule, is gradually released from the inclusion body, and a faint scent is emitted continuously.

  In addition, the scented tissue paper of the present invention has a moisture content of 5 to 15% by weight. By setting it as this range, a fragrance | flavor is discharge | released gradually from an inclusion body, and a faint fragrance will be felt continuously.

In the scented tissue paper according to the present invention, it is desirable that the content of cyclodextrin which is an inclusion body in which at least a part of the fragrance is included is 0.1 to 1.0 g / m ² . If it is this content, it will be easy to make it contain in tissue paper, and also shall emit sufficient fragrance. Moreover, as for the tissue paper with a fragrance which concerns on this invention, it is desirable that the fragrance | flavor content rate with respect to cyclodextrin content is 3 to 20 weight%. The scent can be sufficiently emitted.

  Here, the cyclodextrin releases the guest molecule and then takes the guest molecule into the empty space again. Therefore, in the tissue paper with a scent according to the present invention, the fragrance component is diffused when biting the runny nose, and then the tissue paper biting the runny nose is discarded in a trash can etc. As a result, it has a unique effect that it does not have in the conventional tissue paper with a fragrance.

  On the other hand, in the method for producing a scented tissue paper according to the present invention, cyclodextrin, which is a clathrate in which at least a part is clathrated with a fragrance, is mixed with a humectant having a moisture content of 10% by weight or less. Apply to tissue paper. By mixing and applying the clathrate to the moisturizing agent, it is not necessary to separately apply the both to the tissue paper base sheet, and it can be efficiently produced. In addition, by making the moisture content of the humectant 10% by weight or less, the amount of fragrance released from the clathrate during production can be minimized without sacrificing ease of application. The tissue paper can contain a sufficient amount of cyclodextrin in the state of inclusion of a fragrance.

  Moreover, when apply | coating in this way, after mixing the cyclodextrin containing a clathrate and a moisturizer, it is desirable to apply | coat with respect to a tissue paper base paper within 12 hours. After application, moisture is diffused into the tissue paper, reducing the chance of contact between the moisture and the inclusion body and slowing the release of the fragrance, but the mixture of the inclusion body and moisturizer is mixed. In the state, there are many opportunities for contact between the clathrate and moisture, and the perfume is easily released and continues to be released. Therefore, it is not desirable to store the mixed solution after mixing for a long period of time. In the production method of the present invention, it is possible to prevent the release of the fragrance from the excessive clathrate due to the moisture in the moisturizing agent by applying it to the tissue paper base paper within 12 hours after mixing.

  Moreover, in the manufacturing method of the scented tissue paper of this invention, it is desirable that the fragrance | flavor content rate with respect to cyclodextrin content shall include 3 to 20 weight%. The moisture in the tissue paper will slowly release the fragrance.

  As described above, according to the present invention, there is provided a scented tissue paper that is excellent in smoothness and softness, is easy to manufacture, is low in cost, and safer than the conventional one, and a method for manufacturing the tissue paper.

It is sectional drawing of the two-ply tissue paper based on this invention. It is a figure for demonstrating generation | occurrence | production of the fragrance in the tissue paper which concerns on this invention. It is a figure for demonstrating the deodorizing effect in the tissue paper which concerns on this invention.

  Below, embodiment of the tissue paper with a fragrance concerning this invention is explained in full detail, referring drawings. The scented tissue paper according to the present invention is a tissue paper containing cyclodextrin and a moisturizing agent, which is a clathrate in which at least a part of the tissue paper includes a fragrance.

The tissue paper with fragrance according to the present embodiment has a two-ply or three-ply ply structure, and the basis weight according to JIS P 8124 is 10 to 20 g / m ² per ply. If it is less than 10 g / m ² , it tends to be broken at the time of use, and if it exceeds 20 g / m ² , the raw material cost becomes high and the softness is hardly expressed. The paper thickness of the scented tissue paper according to the present embodiment is preferably 100 to 200 μm, and more preferably 110 to 150 μm. When the paper thickness is out of the above range, it is not preferable in terms of strength and softness as tissue paper. The paper thickness was adjusted 5 times under the conditions of JIS P 8111 (1998) and then using a dial thickness gauge (thickness measuring instrument) “PEACOCK G type” (manufactured by Ozaki Seisakusho) under the same conditions. The average value measured.

  The sheet constituting the ply of the scented tissue paper according to the present invention is a crepe paper, which is a papermaking raw material in which a known agent such as a dry paper strength agent or a wet strength agent is added to a pulp slurry. Papermaking can be done with a papermaking facility with a Yanki dryer.

  The pulp raw material in the scented tissue paper according to the present invention is preferably composed of NBKP (conifer kraft pulp) and LBKP (hardwood kraft pulp). Although used paper pulp may be blended as appropriate, it is desirable that it is composed only of NBKP and LBKP of virgin pulp because it is desirable in terms of the texture of the resulting tissue paper. In this case, the blending ratio (JIS P 8120) is preferably NBKP: LBKP = 20: 80 to 80:20, and particularly preferably NBKP: LBKP = 30: 70 to 60:40.

  On the other hand, an inclusion body in which a fragrance component is included in a cyclodextrin according to the present invention is produced by including a fragrance component in a known cyclodextrin by a known method such as an emulsification method or a saturated aqueous solution method. be able to. This cyclodextrin is generally classified into α-cyclodextrin (6 glucose), β-cyclodextrin (7 glucose), and γ-cyclodextrin (8 glucose) depending on the number of glucose bound. The β and γ cyclodextrins have different inner diameters, and take in guest molecules corresponding to the inner diameters. The inner diameter is 0.5 to 0.6 nm for α-cyclodextrin, 0.7 to 0.8 nm for β-cyclodextrin, and 0.9 to 1.0 nm for γ-cyclodextrin. The type of cyclodextrin used in the present invention may be determined as appropriate in relation to the fragrance component, and is not necessarily limited. However, β-cyclodextrin is particularly suitable because it is inexpensive, hardly dissolves in water and has excellent handleability. .

  On the other hand, the fragrance according to the present invention may be appropriately selected according to the type of cyclodextrin, and is not particularly limited, but specific examples include Ryusen Incense, Benzo, Kaigo Incense, Lance Cat Incense, Clove Oil. , Galvanum, jasmine absolute, labutnam, mate tea, merilot, mimosa, musk tonkin, myrrh, oak moss or moss de chine, milk incense, peony incense, oris, baturi, rosemary oil, sandalwood oil, vetiver oil, violet leaf absolute , Higher alcohol, aldehyde, benzaldehyde, benzoic acid, cinnamic acid, cinnamic aldehyde, cinnamic alcohol, coumarin, ester, indole, ketone, salicylic acid and related compounds, terpenoids, vanillin and various synthetic fragrances or two of these The above mixture It can gel. Commercial products can also be used.

  Among fragrances, l-menthol has a skin irritation effect in addition to mint flavor and is particularly refreshing and refreshing. It is used for applications such as biting the runny nose, which is a mint-based fragrance ingredient, and for wiping the mouth. It is suitable as a perfume component of tissue paper and has good compatibility with the above-mentioned inexpensive β-cyclodextrin and is included as a guest molecule. Therefore, in the tissue paper with a fragrance according to the present invention, one containing a clathrate in which 1-menthol is clathrated as a guest molecule in β-cyclodextrin can be shown as an example of a desirable combination.

  On the other hand, in the tissue paper according to the present invention, the moisture content is 5 to 15% by weight. The moisture content is 4 under the temperature of 105 ± 3 ° C. based on the weight of the tissue paper when the humidity is adjusted for 24 hours in a temperature of 23 ° C. and humidity of 50% RH in accordance with JIS P 8111 (1998). It is dried for a period of time in an absolutely dry state, and the amount of moisture contained in the tissue paper is calculated by subtracting the weight of the tissue paper at the time of the absolutely dry, and the amount of moisture in the above-mentioned temperature 23 ° C., humidity 50% RH environment It is a value calculated by dividing by the weight of tissue paper when humidity is adjusted for 24 hours.

  When the moisture content in the tissue paper is less than 5% by weight, the fragrance is not easily released from the clathrate and the fragrance cannot be sufficiently felt. On the other hand, if the moisture content exceeds 15% by weight, the fragrance is likely to be excessively released from the clathrate, resulting in poor scent sustainability. Here, the moisture content can be easily achieved by including a humectant.

  Here, there are various humectants used for tissue paper, but water-based moisturizers mainly composed of water and polyol (usually also called “water-based chemicals” or “water-based lotion chemicals”), mainly water-insoluble waxes, etc. And an oil-based moisturizing agent (usually called “oil-based chemical solution” or “oil-based lotion chemical solution”) that is semi-solid at room temperature. Specific examples of the water-based humectant include those containing about 90 to 95% by weight of polyol such as glycerin and propylene glycol and about 5 to 10% by weight of water. As specific examples of the oil-based humectant, the main components are waxes and fats and oils, and they are generally liquid or semi-solid (cream) at room temperature and normal pressure. Examples of the fats and oils include white petrolatum, liquid paraffin, coconut oil, palm oil, and saturated fatty acids such as palmitic acid.

  When applied to a sheet, the aqueous humectant has excellent affinity with pulp fibers constituting the sheet, impregnates in the thickness direction of the sheet (also referred to as the Z direction), and acts to modify the entire sheet. The oil-based humectant mainly acts to coat the surface, and particularly improves the smoothness of the surface. The moisturizing agent according to the present invention may be either an aqueous moisturizing agent or an oily moisturizing agent, but when it is an aqueous moisturizing agent, moisture is always taken into the paper due to moisture absorption by the polyol. As a result, the inclusion body releases a fragrance as a guest molecule, and a faint scent is emitted more continuously. In the case of oil-based moisturizers, the moisture content of the moisturizer itself by emulsification and the hygroscopicity of the tissue paper base sheet can be easily adjusted to a water content of 5 to 10% by weight. A moisture content of weight percent can be facilitated.

  The cyclodextrin used in the tissue paper with fragrance according to the present invention, which is a clathrate in which at least a part is clathrated with a fragrance, preferably has a fragrance content of 3 to 20% by weight with respect to the cyclodextrin. More preferably, it is 3-18 weight%, Most preferably, it is 5-15 weight%. If it is cyclodextrin partially containing clathrate containing this level of fragrance, it should be able to feel a scent at the above moisture content and be excellent in its sustainability Can do. In other words, the scented tissue paper according to the present invention desirably has a fragrance content of 3 to 20% by weight, more preferably 3 to 18% by weight, and particularly preferably 5% by weight with respect to the cyclodextrin content. It is ˜15% by weight. If it is this range, a fragrance will be fully felt combined with the moisture content of tissue paper, and it will be excellent in sustainability.

In addition, the content of cyclodextrin, which is a clathrate in which a part of the present invention includes a fragrance, can be appropriately determined depending on the fragrance tone and the strength of the fragrance. In this case, it is 0.1 to 1 g / m ² . If it is less than 0.1 g / m ² , the scent may not be sufficiently felt, and if it exceeds 1 g / m ² , the scent may become too strong.

  On the other hand, in manufacturing the scented tissue paper according to the present invention, in order to make the tissue paper contain dextrin containing inclusion bodies, this dextrin is dispersed in a moisturizing agent that imparts moisture retention to the tissue paper, and the moisturizing The agent is preferably applied to the tissue paper base. However, since the clathrate using cyclodextrin releases guest molecules in the presence of water, the moisture content in the moisturizing agent is 10% by weight or less. Further, in order to reduce the amount of the fragrance component diffused at the time of application, the time from mixing the clathrate with the moisturizing agent to applying it to the tissue paper base is within 12 hours at most, preferably 4 hours. And more preferably within 1 hour after mixing. In particular, when the clathrate is dispersed in an aqueous humectant and applied to tissue paper, the moisture in the humectant is absorbed and diffused between the fibers immediately after application, so that the clathrate is relatively coated. To stay in. Accordingly, the opportunity for contact between the clathrate and moisture is reduced immediately after application, and it is less likely to be affected by moisture in the humectant after application. Therefore, in applying the humectant, the yield of the fragrance can be improved by shortening the period of the state of the mixed liquid in which cyclodextrin is dispersed in the humectant. Of the cyclodextrins, β-cyclodextrin tends to stay on the coated surface.

  The amount of the moisturizing agent applied to the tissue paper according to the present invention is preferably 10 to 35% by weight of the tissue paper base paper. Particularly in the case of an oily humectant, the content is desirably 10 to 30% by weight. If the amount is less than 10% by weight, the improvement of the surface smoothness by the oil-based moisturizing agent may not be sufficient, and if it exceeds 30% by weight, stickiness may be felt. When an aqueous chemical solution is used, the coating amount is preferably 15 to 35% by weight of the tissue paper base paper. If it is less than 15% by weight, the flexibility may not be sufficiently improved, and if it exceeds 35% by weight, stickiness may be felt.

  On the other hand, the preferable position which contains the cyclodextrin containing the inclusion body in the tissue paper with a fragrance which concerns on this invention is the surface of a tissue paper, and a back surface. As shown in FIG. 1, when two plies which are the preferable forms of the tissue paper 100 are taken, they are laminated outer surfaces A and A (in the figure, each ply is indicated by a symbol P). The laminated inner surface (the surface where the plies P, P are facing each other) has a tendency to unintentionally shorten the period during which the scent is emitted because moisture due to moisture absorption tends to accumulate and is difficult to evaporate.

  When the laminated outer surfaces A and A are as described above, a large amount of water contained in the runny nose 20 comes into contact with the clathrate 10 and 10 when the nose is bitten with tissue paper 100 during use, as shown in FIG. In that case, cyclodextrin 11,11 ... releases perfume ingredients 12,12 ... which are guest molecules, and emits a sufficient scent G.

  And since cyclodextrin 11,11 ... discharge | releases the fragrance | flavor 12,12 ... which is a guest molecule as above-mentioned, in order to take in a guest molecule again, in the tissue paper 100 with a fragrance which concerns on this invention, as shown in FIG. When the fragrance component is released after biting the runny nose, if it is discarded in the trash, the off-flavor components 13, 13 ... in the trash can be taken up as guest molecules by the cyclodextrins 11, 11 ... Deodorizing function is demonstrated.

  On the other hand, in the scented tissue paper according to the present invention, for example, a bundle of a plurality of tissue papers is stored in a rectangular parallelepiped storage box, and the upper surface of the storage box (also called a carton box or tissue carton). Tissue paper products that are used by sequentially pulling out tissue paper one by one from the take-out port provided in the container (when the sheet is taken out, the next sheet is continuously pulled out from the take-out port is called a pop-up type). it can.

  Such tissue paper products can be manufactured with known manufacturing equipment for this type of product. For example, a rotary interfolder or a multi-stand interfolder can be used for manufacturing a bundle.

  Next, Examples and Comparative Examples of the scented tissue paper according to the present invention were prepared, and the fragrance strength and the like were evaluated. Each example is a two-ply tissue paper, and the basis weight per ply is as shown in Table 1 below. In addition, each column of Table 1 shows the following matters.

[Fragrance holder]
It refers to both cyclodextrins that are partly clathrate-clad inclusions and microcapsules that are partly encapsulated with fragrances. The column of “perfume retentate” indicates whether it is a cyclodextrin or a microcapsule, and the column of “perfume content” indicates the content ratio of the perfume to the cyclodextrin or microcapsule.

(Coating chemical composition)
Examples 1 to 5 and Comparative Example 3 were produced by applying a coating chemical solution, in which cyclodextrin, a part of which is a clathrate containing a fragrance, mixed with a moisturizing agent, to tissue paper. Comparative Examples 1 and 2 were produced by applying a coating chemical solution in which a microcapsule encapsulating a fragrance was mixed with a moisturizing agent to tissue paper. This column shows the composition of the coating chemical.
The “Humectant Type” column indicates whether the moisturizer is aqueous or oil-based, the “Humectant” column indicates the ratio of the moisturizer in the applied chemical solution, and the “Fragrance Holder” column. Indicates the proportion of the fragrance holder in the coating chemical solution, and the column of “moisture content” indicates the proportion of moisture in the coating chemical solution.

[Coating amount and content]
The coating amount and the content indicate the amount of the chemical solution applied to the tissue paper base and the amount of the humectant contained in the tissue paper after coating. “Amount of chemical applied” in this column is the amount of applied chemical applied to tissue paper, “Moisturizer content” is the amount of moisturizer contained in the tissue paper according to each example, “fragrance holder content” Is the amount of the fragrance holder contained in the tissue paper according to each example, and “chemical solution application ratio” indicates the ratio of the chemical solution to the basis weight of 1 ply.

[Dry tensile strength, wet tensile strength]
The dry tensile strength and the wet tensile strength are values measured based on JIS P 8113 (1998) of the tissue paper according to each example. The width of the test piece at the time of measurement was 25 mm. It is understood whether this item has the strength required for tissue paper.

[Softness]
The softness is a value measured according to the handle ohm method according to the JIS L 1096 E method. However, the test piece was 100 mm × 100 mm in size, and the clearance was 5 mm. The measurement was performed 5 times each in the vertical direction and the horizontal direction with 1 ply, and the average value of all 10 times was defined as one decimal point and expressed in units of cN / 100 mm. This item helps you understand the softness of tissue paper.

[Moisture content]
The moisture content is 4 under the temperature of 105 ± 3 ° C. based on the weight of the tissue paper when the humidity is adjusted for 24 hours in a temperature of 23 ° C. and humidity of 50% RH in accordance with JIS P 8111 (1998). It is dried for a period of time in an absolutely dry state, and the amount of moisture contained in the tissue paper is calculated by subtracting the weight of the tissue paper at the time of the absolutely dry, and the amount of moisture in the above-mentioned temperature 23 ° C., humidity 50% RH environment It is a value calculated by dividing by the weight of tissue paper when humidity is adjusted for 24 hours.

[Evaluation]
“Scent intensity”, “moist feeling”, “smoothness”, “softness”, and “deodorizing effect” were evaluated in five stages as sensory evaluations by 20 subjects. The numerical values in the table are rounded off from the average value of the subjects to give an integer value.
“Scent persistence” is 720 hours equivalent to 3 years, 480 hours equivalent to 2 years, 240 hours equivalent to 1 year, according to an accelerated deterioration test at a temperature of 50 ° C. and a humidity of 50% RH. The time was evaluated as 3 months and 20 hours as 1 month.
The criteria of “scent of scent” are 5: feels fragrance considerably, 4: feels fragrance, 3: feels fragrance a little, 2: feels less fragrance, 1: does not feel fragrance, Or the scent is too strong.
The standard of “scent persistence” is 5: unopened and the scent is maintained for about 3 years after manufacture, 4: unopened and the scent is maintained for about 2 years after manufacture, 3: unopened and after manufacture The scent is maintained for about a year. 2: The scent is maintained for about three months after production when unopened. 1: The scent is maintained for less than one month after manufacture without being opened.
The standard of “moist feeling” is 5: feel a moist feeling considerably 4: feel a moist feeling 3: feel a little moist feeling 2: feel a little moist feeling 1: not feel a moist feeling.
The standard of “smoothness” is 5: smoothness is quite good, 4: smoothness is good, 3: smoothness is good, 2: smoothness is slightly bad, 1: smoothness is bad, or stickiness is felt is there.
The criteria for "softness" are 5: softness is quite good, 4: softness is good, 3: softness is good, 2: softness is bad, 1: softness is bad.
The criteria for the “deodorizing effect” are 5: feel the deodorizing effect considerably, 4: feel the deodorizing effect, 3: feel a little deodorizing effect, 2: feel less deodorizing effect, 1: deodorizing effect I don't feel.

  First, there is no big difference in the dry tensile strength and wet tensile strength of each example and each comparative example of the present invention, and each example can be used for normal use of tissue paper.

  And Example 1-5 has confirmed that the intensity | strength of favorable fragrance, persistence of fragrance, and a deodorizing effect were exhibited. Comparative Examples 1 and 2 are examples in which a scent is imparted using conventional microcapsules without using cyclodextrin, and the same effect is obtained in the strength and durability of the scent, but the microcapsules are deodorized. There is no effect, and the process of breaking the microcapsules by friction is necessary for the release of scent.

  Next, a test was conducted with respect to suitable production conditions for the scented tissue paper according to the present invention. The production conditions of each example are as shown in Table 2 below. In Example 1, cyclodextrin which is an inclusion body in which a fragrance is included is mixed with a humectant having a water content of 10% by weight. After stirring for 10 hours, it was immediately applied to tissue paper. In Comparative Example 1, the stirring time in Example 1 was 20 hours. In Comparative Example 3, the moisture content of the humectant was set to 15% by weight in Example 1.

  Looking at the results in Table 2, the effect of the moisturizing agent was exhibited in each example, and there was no significant difference in the evaluation of moist feeling, smoothness and softness. However, in Comparative Example 1 and Comparative Example 2, the scent persistence was very low compared to Example 1. It is considered that the perfume in the clathrate has been almost released at the time of application. This is also inferred from the fact that there is no difference in the deodorizing effect between Example 1, Comparative Example 1, and Comparative Example 3.

  In this test, the clathrate was mixed with the moisturizing agent, and the moisturizing agent was stirred for a predetermined time and was manufactured under the condition that an excessive load was applied. Therefore, from this test, if the moisture content of the moisturizing agent is at least 10% by weight and the cyclodextrin containing clathrate and the moisturizing agent are mixed and applied within 12 hours, at least the scent according to the present invention It has been shown that a tissue paper with a stick can be produced, and the tissue paper with a scent according to the present invention cannot be produced unless it is produced under these conditions.
