Description

  The present invention relates to a gel-like aroma / deodorant composition containing cellulose fibers and a gel-like aroma / deodorant using the same.

  Gel fragrances and deodorants are easy to avoid spilling even if they fall over, and have long-lasting fragrance and deodorant effects, so they are widely used as fragrances and deodorants. As the gelling agent used in the gel-like fragrance / deodorant, a chemically synthesized gelling agent or a natural gelling agent is used.

  As a conventional gel-like fragrance / deodorant composition, for example, a cross-linked ethylenically unsaturated carboxylic acid polymer classified as a chemically synthesized gelling agent is used as a gelling agent (Patent Document 1), natural type A gellan gum classified as a gelling agent (Patent Document 2) and a xanthan gum classified as a natural gelling agent (Patent Document 3) have been proposed.

JP-A-9-290015 JP 2007-29175 A JP-A-55-81655

  However, in the gel-like fragrance / deodorant composition described in Patent Document 1, since the gelling agent is a chemically synthesized gelling agent, it is safer and biodegradable than natural gelling agents. It is inferior in point, and the product image for consumers is also bad. In addition, the chemical synthesis gelling agent is synthesized from petroleum raw materials and generates carbon dioxide gas by disposal, so that there is a problem that the burden on the global environment is large.

  In the gel-like fragrance / deodorant composition described in Patent Document 2, since the gelling agent is a natural gelling agent, there is no problem when using the chemically synthesized gelling agent. It is necessary to dissolve by heating. Therefore, when a fragrance | flavor and a deodorant component are added in the state where base material temperature is high, there exist problems, such as a fragrance | flavor and a deodorant component denatured or a fragrance | flavor change. In addition, when the product is stored at a high temperature after production, there is a problem that the product is dissolved again and flows out. Such a problem similarly occurs when carrageenan, agar, gelatin or the like other than gellan gum described in Patent Document 2 is used as a gelling agent.

  In the gel-like fragrance / deodorant composition described in Patent Document 3, since the gelling agent is a natural gelling agent, there is no problem when using the chemical synthetic gelling agent. Since it is not necessary to dissolve by heating at times, the problems described in Patent Document 2 can also be solved. However, natural gelling agents such as xanthan gum, which do not need to be heated and dissolved at the time of gel production, have low gel strength, and the gel may be deformed or collapsed by vibration or impact during transportation. If the amount of the gelling agent is increased for the purpose of increasing the gel strength, the handling at the time of manufacture deteriorates, and there is a problem that it becomes difficult to transfer the gel or to fill the container. Such a problem similarly occurs when sodium alginate, carboxymethylcellulose, or the like other than Xanthan gum described in Patent Document 3 is used as a gelling agent.

  The present invention has been made in view of such circumstances, and there is no need for heating at the time of manufacture, and the use of a gel having excellent gel strength prevents alteration of fragrance and deodorant components and changes in fragrance tone. A gel-like fragrance / deodorant composition that can sustain the effects of perfume and deodorant components for a long time, can prevent deformation during transportation, and has good handling during construction, and The purpose is to provide the gel-like fragrance / deodorant used.

In order to achieve the above object, the present invention provides a gel-like fragrance / deodorant containing the following component (A), at least one of component (B) and component (C), and component (D): The composition is the first gist.
(A) Cellulose fibers having a maximum fiber diameter of 1000 nm or less and a number average fiber diameter of 2 to 100 nm, the cellulose having a type I crystal structure, and a hydroxyl group at the C6 position of the glucose unit in the cellulose molecule Cellulose fibers which are selectively oxidized and modified to aldehyde groups and carboxyl groups, and the amount of the carboxyl groups is in the range of 0.6 to 2.0 mmol / g.
(B) Fragrance.
(C) Deodorant component.
(D) Water.

  The second gist of the present invention is a gel-like aroma / deodorant comprising the gel-like aroma / deodorant composition.

  That is, the present inventors do not need heating at the time of manufacture, and can use the gel excellent in gel strength to prevent the perfume and deodorant components from deteriorating and changing the scent, and the perfume and deodorant. In order to obtain a gel-like fragrance / deodorant composition that can maintain the effects of the components for a long time, prevent deformation during transportation, and have good handling during production, the present inventors have conducted extensive research. In the course of the research, a cellulose fiber having a maximum fiber diameter of 1000 nm or less and a number average fiber diameter of 2 to 100 nm, the cellulose having a type I crystal structure and the C6 position of the glucose unit in the cellulose molecule When the cellulose fiber in which the hydroxyl group is selectively oxidized and modified to an aldehyde group and a carboxyl group and the amount of the carboxyl group is in the range of 0.6 to 2.0 mmol / g is dispersed at room temperature, Since it gels by leaving it to stand, it has been found that it does not need to be dissolved by heating at the time of gel production, unlike conventional natural gelling agents, and it has excellent gel strength. And as a result of further research, by combining at least one of the specific cellulose fiber and the fragrance and deodorant component, it is possible to prevent the deterioration of the fragrance and deodorant component due to heating, the change of the fragrance, It has been found that a gel-like fragrance / deodorant composition can be obtained that can sustain the effects of the odorant and deodorant components for a long time, prevent deformation during transportation, and handle well during production. The invention has been reached.

  Thus, since the gel-like fragrance / deodorant composition and the gel-like fragrance / deodorant of the present invention use a specific cellulose fiber (component A) as a gelling agent, the following effects can be obtained. Can do.

(1) The specific cellulose fiber (component A) that is the gelling agent gels by being dispersed and allowed to stand at room temperature, and thus does not need to be heated during production. Therefore, the gel-like fragrance / deodorant composition of the present invention in which the specific cellulose fiber (component A) is combined with at least one of the fragrance (component B) and the deodorant component (component C) is obtained by heating. It is possible to prevent alteration of the fragrance (B component) and deodorant component (C component) and change in fragrance, and the effect of the fragrance (B component) and deodorant component (C component) can be maintained for a long time.

(2) Since the specific cellulose fiber (component A) used as the gelling agent does not re-dissolve by heating, there is no fear of re-dissolving and flowing out even when the product is stored at a high temperature after production.

(3) Since the specific cellulose fiber (component A) is in a single nanofiber state of cellulose to form a gel, the gel strength is high, and the gel deforms or collapses due to vibration or impact during transportation. There is little fear to do.

(4) The specific cellulose fiber (component A) has a very high thixotropy index, has a low viscosity at the time of mixing (dispersion) or immediately after mixing, and increases in viscosity when left after mixing (dispersion). There is a characteristic of becoming. Therefore, the viscosity of the composition is low during the manufacturing process, that is, immediately after the dispersion treatment and immediately after the dispersion treatment, handling is easy, and transfer of the process liquid and product filling are easy. After the product is filled, the gelation is further promoted by leaving it for a certain period of time.

(5) Since the specific cellulose fiber (component A) is a natural gelling agent obtained from cellulose, which is a natural material, it is excellent in safety and biodegradability and has a good product image for consumers. Furthermore, since the specific cellulose fiber (A component) which is the said gelatinizer is a cellulosic raw material which can be recirculated, there is also little load with respect to global environment.

  And when the said specific cellulose fiber (A component) is what was oxidized using a co-oxidant in presence of N-oxyl compound, by adjusting the usage-amount and oxidation time of a co-oxidant, Dispersion stability becomes better.

  Moreover, the characteristic of a gelatinizer improves that content of the said specific cellulose fiber (A component) is the range of 0.2 to 5.0 weight% of the whole gel-like aroma and deodorant composition. In addition, handling is further improved and economy is excellent.

  Next, an embodiment for carrying out the present invention will be described.

  The gel-like aroma / deodorant composition of the present invention comprises a specific cellulose fiber (component A), at least one of a fragrance (component B) and a deodorant component (component C), and water (component D). Can be obtained.

  In the present invention, the specific cellulose fiber (component A) is a cellulose fiber having a maximum fiber diameter of 1000 nm or less and a number average fiber diameter of 2 to 100 nm, and the cellulose has an I-type crystal structure. In addition, the hydroxyl group at the C6 position of the glucose unit in the cellulose molecule is selectively oxidized to be modified into an aldehyde group and a carboxyl group, and the amount of the carboxyl group is in the range of 0.6 to 2.0 mmol / g. Cellulose fiber (component A) is used, and this is the greatest feature. This fine cellulose fiber (component A) is a fiber obtained by surface oxidizing a cellulose solid raw material derived from a natural product having an I-type crystal structure and miniaturizing it to nano size. Cellulose derived from natural products, which is the raw material, almost always has nanofibers called microfibrils that are bundled in a multi-bundle structure and have a higher order structure. Can not. The specific cellulose fiber (component A) used in the present invention introduces an aldehyde group and a carboxyl group by oxidizing a part of its hydroxyl group, and hydrogen between the surfaces, which is the driving force of strong cohesion between microfibrils. Cellulose fibers that have been weakened in bonding, dispersed, and could not be refined conventionally have been refined to nano size.

  The specific cellulose fiber (component A) has a maximum fiber diameter of 1000 nm or less and a number average fiber diameter of 2 to 100 nm. From the viewpoint of dispersion stability, the maximum fiber diameter is preferably 500 nm or less and several The average fiber diameter is 3 to 80 nm. That is, when the number average fiber diameter of the component A is less than 2 nm, it is essentially dissolved in the dispersion medium. Conversely, when the number average fiber diameter exceeds 100 nm, the cellulose fibers are precipitated, and the cellulose fibers It is because the functionality by blending cannot be expressed.

  The maximum fiber diameter and the number average fiber diameter of the specific cellulose fiber (component A) can be measured, for example, as follows. That is, a sample diluted with water added to cellulose fibers is dispersed and cast on a carbon film-coated grid that has been subjected to a hydrophilic treatment, and this is observed with a transmission electron microscope (TEM). From the obtained image, The maximum fiber diameter and the number average fiber diameter of the cellulose fiber can be measured and calculated.

  The cellulose constituting the specific cellulose fiber (component A) has an I-type crystal structure, for example, in the diffraction profile obtained by wide-angle X-ray diffraction image measurement, Theta can be identified by having typical peaks at two positions near 22 to 23 °.

  Moreover, the carboxyl group amount of the said specific cellulose fiber (A component) is 0.6-2.0 mmol / g, and the range of 0.75-2.0 mmol / g is preferable from the point of dispersion stability. That is, when the amount of carboxyl groups of the cellulose fiber (component A) is less than 0.6 mmol / g, the dispersion stability of the cellulose fiber (component A) is poor, and precipitation of the cellulose fiber (component A) may occur. Also, the dispersion stability of the hydrophobic solid is lowered. Conversely, if the amount of carboxyl groups in the cellulose fiber (component A) exceeds 2.0 mmol / g, the water-solubility of the cellulose fiber (component A) becomes strong, and the expression of effects specific to the cellulose fiber (component A) decreases. Because it does.

  The measurement of the carboxyl group amount of the specific cellulose fiber (component A) can be performed, for example, by potentiometric titration. That is, the dried cellulose fiber is dispersed in water, 0.01N aqueous sodium chloride solution is added, and the cellulose fiber is dispersed by sufficiently stirring. Next, 0.1N hydrochloric acid solution is added until the pH reaches 2.5 to 3.0, and 0.04N aqueous sodium hydroxide solution is added dropwise at a rate of 0.1 ml / min. The amount of carboxyl groups can be calculated from the difference between the neutralization point of excess hydrochloric acid and the neutralization point of carboxyl groups derived from cellulose fibers.

  In addition, adjustment of a carboxyl group amount can be performed by controlling the addition amount and reaction time of the co-oxidant used at the oxidation process of a cellulose fiber so that it may mention later.

Whether or not only the hydroxyl group at the C6 position of the glucose unit constituting the specific cellulose fiber (component A) is selectively oxidized to an aldehyde group and a carboxyl group can be confirmed by, for example, ¹³ C-NMR analysis. . That is, the 62 ppm peak corresponding to the C6 position of the primary hydroxyl group of the glucose unit, which can be confirmed on the ¹³ C-NMR chart of cellulose before oxidation, disappears after the oxidation reaction, and instead a peak derived from the carboxyl group at 178 ppm. It can be confirmed from appearing.

  Next, as the fragrance (B component) used together with the specific cellulose fiber (A component), for example, hydrocarbons, alcohols, aldehydes, ketones, esters, phenols, ethers, lactones, Examples thereof include carboxylic acids, musks, and essential oils. These may be used alone or in combination of two or more.

  The content of the fragrance (component B) is preferably in the range of 0.1 to 20% by weight, particularly preferably in the range of 1 to 15% by weight of the entire gel-like fragrance / deodorant composition.

  Next, examples will be described together with comparative examples. However, the present invention is not limited to these examples.

  First, prior to Examples and Comparative Examples, cellulose fibers were produced as follows.

[Production of Cellulose Fiber T1 (for Examples)]
After adding 150 g of water, 0.025 g of sodium bromide, and 0.025 g of 2,2,6,6-tetramethylpiperidinooxy radical (TEMPO) to 2 g (dry weight) of softwood pulp, the mixture is thoroughly stirred and dispersed. 13% by weight sodium hypochlorite aqueous solution (co-oxidant) was added so that the amount of sodium hypochlorite was 5.4 mmol / g-cellulose with respect to 1 g of pulp, and the pH was maintained at 10-11. The reaction was continued until no pH change was observed while adding a 0.5 N aqueous sodium hydroxide solution dropwise (reaction time: 120 minutes). After completion of the reaction, 0.1N hydrochloric acid was added for neutralization, followed by purification by repeated filtration and washing to obtain cellulose fiber T1 having an oxidized fiber surface.

[Production of Cellulose Fibers T2, T3 (for Examples) and Cellulose Fibers H1, H2 (for Comparative Examples)]
Each cellulose fiber was produced according to production of the cellulose fiber T1, except that the amount of sodium hypochlorite aqueous solution to be added and the reaction time were changed as shown in Table 1 below.

  Using the cellulose fibers T1 to T3 (for examples) and the cellulose fibers H1 and H2 (for comparative examples) obtained in this way, each item was measured according to the following criteria. These results are also shown in Table 1 above.

<Maximum fiber diameter, number average fiber diameter>
Samples diluted with water added to each cellulose fiber were treated at 12000 rpm for 15 minutes using a homomixer, cast onto a carbon film-coated grid that had been hydrophilized, and this was transmitted through a transmission electron microscope (TEM) (Japan). The number average fiber diameter and the maximum fiber diameter were measured and calculated from an image (magnification: 10,000 times or 50000 times) obtained by JEM-1400 manufactured by Denki Co., Ltd. The maximum fiber diameter and number average fiber diameter measured by this method are the maximum fiber diameter and number average fiber of the cellulose fibers in the gel-like aroma / deodorant composition of the present invention obtained in the examples described later. It is confirmed that it matches the diameter.

<Measurement of carboxyl group content>
The quantification of the carboxyl group on the cellulose fiber surface was performed by potentiometric titration. That is, 0.3 g of each dried cellulose fiber was dispersed in 55 ml of water, 5 ml of 0.01 N sodium chloride aqueous solution was added, and the mixture was sufficiently stirred to disperse the cellulose fibers. Next, 0.1N hydrochloric acid solution is added until the pH reaches 2.5 to 3.0, and 0.04N aqueous sodium hydroxide solution is added dropwise at a rate of 0.1 ml / min. The amount of carboxyl groups was calculated from the difference between the neutralization point of excess hydrochloric acid and the neutralization point of carboxyl groups derived from cellulose fibers.

<Measurement of aldehyde group amount>
The amount of aldehyde groups on the surface of the cellulose fiber (sample) was measured as follows. That is, the sample was dispersed in water, and the amount of carboxyl groups in the sample obtained by oxidizing all aldehyde groups to carboxyl groups using sodium chlorite under acetic acid acidity was measured. From the difference in the amount of carboxyl groups before oxidation, Base weight was calculated.

<Confirmation of cellulose I type crystal structure>
It was confirmed as follows that each of the cellulose fibers had an I-type crystal structure. That is, the diffraction profile obtained by wide-angle X-ray diffraction image measurement has typical peaks at two positions near 2 theta = 14 to 17 ° and 2 theta = 22 to 23 °. It was confirmed to have a crystal structure. As a result, it was confirmed that the cellulose fibers T1 to T3 (for Examples) and the cellulose fibers H1 and H2 (for Comparative Examples) have an I-type crystal structure.

<Confirmation of aldehyde group and carboxyl group>
Whether or not only the hydroxyl group at the C6 position of the glucose unit constituting each cellulose fiber was selectively oxidized to an aldehyde group and a carboxyl group was confirmed as follows. That is, the 62 ppm peak corresponding to the C6 position of the primary hydroxyl group of the glucose unit confirmed on the ¹³ C-NMR chart of cellulose before oxidation disappeared after the oxidation reaction, and instead a peak derived from the carboxyl group at 178 ppm. Was confirmed by the appearance of As a result, the cellulose fibers T1 to T3 (for Examples) and the cellulose fibers H1 and H2 (for Comparative Examples) also have a carboxyl group and an aldehyde group formed by oxidizing the hydroxyl group at the C6 position of the glucose unit in the cellulose molecule. It was confirmed.

  Next, using the cellulose fibers (T1 to T3, H1, H2) obtained above, a gel-like fragrance / deodorant composition was prepared as follows.

[Example 1]
The cellulose fiber T1 which is the specific cellulose fiber (component A) is 1.50 parts by weight (hereinafter abbreviated as “part”) in terms of solid content, and 0.30 part of citrus flavor as a flavor (component B), A predetermined amount of water was added to make 100 parts. Next, this blend was treated at 12000 rpm for 15 minutes using a vacuum emulsifier at a temperature of 25 ° C. to obtain a gel-like fragrance composition. The obtained gel-like fragrance composition was filled in a 300 ml capacity container using a transfer pump and allowed to solidify by being left at 25 ° C. for one day.

[Examples 2 and 3, Comparative Examples 1 to 6]
As shown in Table 2 and Table 3 below, a gel-like fragrance composition was obtained in accordance with Example 1 except that the type and amount of each component were changed. The obtained gel-like fragrance composition was filled in a 300 ml capacity container using a transfer pump and allowed to solidify by being left at 25 ° C. for one day.

  In addition, content of the cellulose fiber in a table | surface shows solid content conversion amount (following, the same).

  Using each composition thus obtained, each property was evaluated according to the following criteria. These results are shown in Tables 2 and 3 above.

<Scent>
As a standard solution for fragrance evaluation, a composition containing a fragrance or a deodorant having the same concentration except for a gelling agent was prepared in a container. This standard solution was compared with the scent of the obtained gel-like fragrance / deodorant by sensory evaluation, and judged according to the following criteria.
○: The same scent as the standard solution.
Δ: Slightly worse aroma than standard solution.
X: Scent is considerably worse than the standard solution.

<Gel strength>
The gel-like fragrance / deodorant filled in the container was laid down, and the degree of gel collapse was visually determined according to the following criteria.
○: The gel does not collapse.
Δ: The gel partially disintegrates.
X: The gel completely disintegrates or flows.

<Filling into containers>
The state when filling the container with the transfer pump was visually determined according to the following criteria.
○: Can be transferred and filled with a transfer pump without problems.
Δ: It takes time, but somehow it can be transferred and filled with a transfer pump.
×: Cannot be transferred / filled with a transfer pump.

  As is clear from the results of Table 2 and Table 3 above, the products of Examples 1 to 3 have no change in fragrance during production, have gel strength, and have good evaluation of filling into containers. Excellent handling and workability during manufacturing. In addition, instead of the cellulose fibers T1 to T3, the present inventors also use cellulose fibers T1 to T3 when cellulose fibers having a carboxyl group amount of 0.6 mmol / g (lower limit) are used. It was confirmed by experiments that the same excellent effect was obtained. Further, even when the content (solid content weight) of specific cellulose fibers was changed to 0.2% by weight and 5.0% by weight of the whole composition, the gel strength was slightly changed, but the examples and It was confirmed by experiments that the same excellent effect was obtained.

  On the other hand, it replaced with cellulose fiber T1-T3 of an Example goods, and the comparative example 1 goods using gellan gum could not be made into a gel form, without solidifying. This is because the cellulose fiber of the example product can be gelled at room temperature without heating, but the gellan gum used for the comparative example 1 product is a natural gelling agent, but it must be heated. This is because it does not gel.

  In order to compare the gellan gum and the cellulose fiber of the example product, the gel-like fragrance composition was prepared according to Comparative Example 1 except that the production conditions for gellan gum solidify, that is, the dispersion / filling temperature was 90 ° C. In Comparative Example 2 prepared, the gel strength and the evaluation of filling into the container were the same as in the Example product, but the evaluation of fragrance was inferior. This is because the perfume has deteriorated because it was heated at the time of manufacture for the purpose of solidifying gellan gum.

  From the results of the above Examples 1 to 3 and Comparative Examples 1 and 2, when gellan gum was used as the gelling agent, the gel could not be prepared unless heated during production. When heated at the time of manufacture, the fragrance changed in quality, and a fragrant gel-like fragrance / deodorant could not be obtained. On the other hand, when the cellulose fiber of the example product is used as a gelling agent, gelation is possible without heating, so there is no deterioration of the fragrance and a fragrant gel-like fragrance / deodorant is obtained. It was.

  In place of the cellulose fibers T1 to T3 of the example product, the comparative example 3 product to which xanthan gum was added at the same concentration was inferior in gel strength and filling into the container. Moreover, in order to improve the gel strength of the Comparative Example 3 product, the Comparative Example 4 product in which the amount of xanthan gum added was increased was extremely poor in handling during production, and could not be filled into the container.

  From the results of the above Examples 1 to 3 and Comparative Examples 3 and 4, when xanthan gum, which is a natural gelling agent, is used as the gelling agent, there is no need for heating during production, and no fragrance deterioration occurs. However, when the addition amount is small, the gel strength is insufficient, and when the addition amount is increased to increase the gel strength, the production becomes difficult. On the other hand, when the cellulose fiber of the example product was used as a gelling agent, a gel-like fragrance / deodorant having gel strength and good handleability during production was obtained.

  Instead of the cellulose fibers T1 to T3 of the example product, the comparative example 5 product using the cellulose fiber H1 having a carboxyl group amount less than the lower limit was inferior in gel strength. On the other hand, instead of the cellulose fibers T1 to T3 of the example product, the comparative example 6 product using the cellulose fiber H2 having a carboxyl group amount exceeding the upper limit was inferior in the evaluation of the filling property into the container.

Example 4
The components shown in Table 4 below were blended in the proportions shown in the table, and a predetermined amount of water was added to make 100 parts. Next, this blend was treated at 12000 rpm for 15 minutes using a vacuum emulsifier at a temperature of 25 ° C. to obtain a gel-like fragrance composition. The obtained gel-like fragrance composition is filled into a 300 ml capacity container using a transfer pump and allowed to solidify at 25 ° C. for one day to obtain a gel-like fragrance / deodorant having a lavender scent. It was.

Example 5
A gel-like fragrance / deodorant prepared by emulsifying oil-based cypress oil as a deodorant component (component C) with polyoxyethylene alkyl ether as an emulsifier was prepared. That is, the components shown in Table 4 below were blended in the proportions shown in the same table, and a predetermined amount of water was added to make 100 parts. Next, this blend was treated at 12000 rpm for 15 minutes using a vacuum emulsifier at a temperature of 25 ° C. to obtain a gel-like fragrance composition. The obtained gel-like fragrance composition is filled into a 300 ml capacity container using a transfer pump, and left to stand at 25 ° C. for one day to solidify to obtain a cypress-scented gel-like fragrance / deodorant. It was.

Example 6
A green tea extract was used as a deodorant component (C component) and a green fragrance was used as a fragrance (component B) to obtain a gel-like fragrance / deodorant with a green scent. That is, the components shown in Table 4 below were blended in the proportions shown in the same table, and a predetermined amount of water was added to make 100 parts. Next, this blend was treated at 12000 rpm for 15 minutes using a vacuum emulsifier at a temperature of 25 ° C. to obtain a gel-like fragrance composition. The obtained gel-like fragrance composition is filled into a 300 ml capacity container using a transfer pump and allowed to solidify at 25 ° C. for one day to obtain a gel-like fragrance / deodorant with a green scent. It was.

Example 7
A gel-like fragrance / deodorant having a green scent was obtained in the same manner as in Example 6 except that the same composition as in Example 6 was dispersed using an ultrahigh pressure homogenizer instead of the vacuum emulsifier. .

  Using each composition thus obtained, the fragrance, gel strength, and filling of the container were evaluated according to the above-mentioned criteria. These results are also shown in Table 4 above.

  As is clear from the results in Table 4 above, all the products of Examples 4 to 7 have no change in fragrance during production, have gel strength, and have good evaluation of filling into the container. It was excellent in handling and workability. The gel-like fragrance / deodorant of Example 6 was translucent, whereas the gel-like fragrance / deodorant of Example 7 was transparent. That is, it is understood that a transparent gel-like fragrance / deodorant can be obtained by dispersing using a stronger ultrahigh pressure homogenizer.

  The gel-like fragrance / deodorant composition of the present invention can be filled in an arbitrary container and used as a domestic, commercial, or industrial fragrance or deodorant.
