Description

The present invention relates to volatilizers and volatilization methods.

Currently, various chemical volatilizers for volatilizing chemicals such as fragrances have been proposed and are on the market. For example, a chemical volatilizer is known in which a liquid chemical is stored in a container having an opening at the top, and a rod-shaped volatilizing body is inserted through the opening of the container and soaked in the chemical. In such a chemical volatilizer, the chemical travels along the rod-shaped volatilizer and volatilizes to the outside. Such volatilizers are widely used, especially for fragrances and the like, because they are excellent in interior decoration.

For example, as a conventional chemical volatilizer, Patent Document 1 describes a volatilizer that retains a fragrance and a pigment inside and volatilizes an aromatic component contained in the fragrance.

JP 2004-329794 A

Conventionally, one type of volatilizer has been used for one volatilizer as a volatilizer for volatilizing the aromatic component contained in perfume. However, fragrances usually contain various types of aromatic components in order to express a variety of tones. Since the liquefying speed is also different, the timing of volatilization from the volatilization material was different for each aromatic component. Therefore, in the conventional volatilizer using a single type of volatilizer, each aromatic component in the fragrance is volatilized at different timings, making it difficult to realize a variety of fragrance notes. .

According to the volatilization device and the volatilization method of the present invention, each aromatic component in a perfume can be efficiently volatilized, and various fragrance tone expression can be realized.

FIG. 1 is a perspective view showing an example of one embodiment of the volatilizer of the present invention.

Although the volatilizer and volatilization method of the present invention will be described in detail below, these show examples of desirable embodiments, and the present invention is not limited to these contents.
In this specification, the numerical range "A to B" indicates "A or more and B or less".

FIG. 1 shows an example of one embodiment of the volatilizer of the present invention. The volatilizer 10 of the present invention has a perfume 11 and multiple types of volatilizers 12 for volatilizing the aromatic components contained in the perfume 11 . At least part of the volatilization body 12 is arranged so as to come into contact with the perfume 11 . Moreover, the perfume 11 and a part of the volatilization body 12 may be accommodated in the container 13 as shown in FIG.
In the volatilization device 10 of the present invention, the plurality of types of volatilization bodies 12 are composed of a first volatilization body 12a having a liquid absorption index of 0.65 or more defined by the formula (I) described later, and a first volatilization body 12a having a liquid absorption index of 0.65 or more. It is characterized by including at least the second volatilization body 12b of less than 65. In addition, the number and number of types of volatilizers in the volatilizer of the present invention are not limited to the embodiment shown in FIG.

In addition, the volatilization method of the present invention causes multiple types of volatilizers to absorb the fragrance, and volatilizes the aromatic components contained in the fragrance from the plurality of types of volatilizers. Then, the plurality of types of volatile bodies include a first volatile body having a liquid absorption index of 0.65 or more defined by the following formula (I) and a second volatile body having a liquid absorption index of less than 0.65. characterized by comprising at least

Formula (I): liquid absorption index = liquid absorption time (seconds) of an isoparaffinic solvent having a carbon number of 10 to 16 and a vapor pressure of 0.05 kPa or less (20 ° C.) / 2 mass% POE decyl ether (E.O. 10 mol ) solution absorption time (seconds)
As the isoparaffin-based solvent, for example, IP Solvent 2028 (manufactured by Idemitsu Kosan Co., Ltd.) can be used. As the POE decyl ether, for example, Fine Surf D1310 (manufactured by Aoki Yushi Kogyo Co., Ltd.) can be used. "E.O. 10 mol" means that the average number of mols of ethylene oxide added to decyl ether is 10.

As described above, the volatilization device and the volatilization method of the present invention can efficiently volatilize each aromatic component in the fragrance by using a plurality of types of volatilization bodies with different liquid absorption indices, and various fragrance tones can be obtained. expression can be realized. Although the reason for the above is not necessarily certain, it is presumed as follows.

Since the volatile substance with a large liquid absorption index absorbs oily solvents relatively slowly, the highly lipophilic aromatic components contained in the fragrance begin to smell relatively later, and the fragrance lasts for a relatively long time. will continue. In general, perfumes are divided into three types: highly volatile aromatic components (top), low volatile aromatic components (base), and middle volatility components (middle). However, since aromatic ingredients with high lipophilicity generally tend to have low volatility, the scent of low-volatility aromatic ingredients lasts for a relatively long time. It will be.
On the other hand, since the water-based solvent is absorbed at a relatively high speed, among the aromatic components contained in the perfume, the highly hydrophilic aromatic components begin to smell relatively early, and the fragrance lasts for a relatively short period of time. Since aromatic components with high hydrophilicity generally tend to have high volatility, fragrance components with high volatility start to smell at a relatively early stage.

In addition, since the volatile material having a small liquid absorption index absorbs the oily solvent at a relatively high speed, the highly lipophilic aromatic component among the aromatic components contained in the fragrance begins to smell at a relatively early stage, and the fragrance continues. time is relatively short. Since aromatic components with high lipophilicity generally tend to have low volatility, aromatic components with low volatility begin to smell at a relatively early stage. On the other hand, since the speed at which the water-based solvent is absorbed is relatively slow, among the aromatic components contained in the perfume, the highly hydrophilic aromatic component begins to smell relatively later, and the scent lasts for a relatively long time. Since highly hydrophilic aromatic components generally tend to have high volatility, the fragrance of highly volatile aromatic components lasts for a relatively long time.

By including at least a volatile body having a liquid absorption index of the specific value or more and a volatile body having a liquid absorption index of less than the specific value, with the liquid absorption index bordering on the specific value, each having different volatilization performance It is presumed that the fragrant components can be efficiently absorbed and volatilized, and as a result, various fragrant expressions can be realized.

(vaporized body)
The volatilizer of the present invention contains multiple types of volatilizers. In the present invention, the volatilization body has a function of sucking up the perfume and volatilizing the aromatic component from the surface thereof. The plurality of types of volatile bodies include at least a first volatile body having a liquid absorption index of 0.65 or more defined by the following formula (I) and a second volatile body having a liquid absorption index of less than 0.65. .
Formula (I): liquid absorption index = liquid absorption time (seconds) of an isoparaffinic solvent having a carbon number of 10 to 16 and a vapor pressure of 0.05 kPa or less (20 ° C.) / 2 mass% POE decyl ether (E.O. 10 mol ) solution absorption time (seconds)
Hereinafter, the first volatilization body and the second volatilization body may be simply referred to as volatilization bodies.

An isoparaffin-based solvent (hereinafter simply referred to as an isoparaffin-based solvent) having 10 to 16 carbon atoms and a vapor pressure of 0.05 kPa or less (20 ° C.) in the above formula (I), and 2% by mass POE decyl ether (E.O.10) mol) aqueous solution (hereinafter also simply referred to as a decyl ether aqueous solution) will be described.
First, a capillary of (outer diameter) 1.5 mm×(inner diameter) 1.1 mm×(height) 75 mm sucks up an isoparaffinic solvent or a decyl ether aqueous solution to a height of 5 cm.
Next, the tip of the capillary is brought into contact with the volatilized body, and the volatilized body starts to absorb the isoparaffinic solvent or aqueous decyl ether solution until the volatilized body absorbs all the isoparaffinic solvent or aqueous decyl ether solution in the capillary. Measure the time (seconds) of
The above measurements are performed 10 times for each of the isoparaffin-based solvent and the decyl ether aqueous solution, and the average time is taken as the absorption time (seconds) of the isoparaffin-based solvent or the decyl ether aqueous solution.

If the area of the cross section perpendicular to the longitudinal direction (liquid absorption direction) of the volatilizer is larger than the area of the tip of the capillary, the tip of the capillary is brought into contact with the tip of the volatilizer in the longitudinal direction, and isoparaffinic solvent or decyl ether is used. It shall absorb aqueous solutions. When the area of the cross section perpendicular to the longitudinal direction (liquid absorption direction) of the volatilization body is smaller than the area of the tip of the capillary, the tip of the capillary is brought into contact with the surface near the end of the volatilization body in the longitudinal direction to obtain isoparaffin. It shall absorb system solvent or decyl ether aqueous solution.

The liquid absorption index of the first volatile material is 0.65 or more, and the liquid absorption index of the second volatile material is less than 0.65. In this way, by setting each range with the liquid absorption index of the first volatilizer and the second volatilizer as a boundary of 0.65, each aromatic component in the perfume can be efficiently volatilized, and various It is possible to realize an incense tone expression.
The liquid absorption index of the first volatile material is preferably 0.9 or more, more preferably 1.0 or more, and even more preferably 1.5 or more. Moreover, the liquid absorption index of the second volatile material is preferably less than 0.6, more preferably less than 0.5.

In addition, the difference between the liquid absorption index of the first volatile body and the liquid absorption index of the second volatile body (liquid absorption index of the first volatile body - liquid absorption index of the second volatile body) is preferably 0.3 or more, 0.5 or more is more preferable, and 1.0 or more is even more preferable. Within the above range, each aromatic component in the fragrance can be volatilized more efficiently, and more diverse fragrance tone expressions can be realized.

The liquid absorption index of the volatile material varies depending on the material, composition, size, shape, basis weight (density), fiber length, and fiber direction of the volatile material. It is possible to obtain a volatilized body having. For example, when PET (core) is used, the liquid absorption index can be increased by reducing the basis weight.

The material of the volatilization body is not particularly limited, and is appropriately selected so as to achieve the desired liquid absorption index. Examples of materials for the volatile material include paper, cloth, cork, inorganic minerals, charcoal, plant stems, branches, trunks, leaves, and flowers.
As the paper, for example, volatilization paper, filter paper, crepe paper, calligraphy paper, Japanese paper, Western paper, pulp, special paper (such as wet paper), and the like can be used. The pulp can also be used as a PIM (Pulp Injection Molding) molded product.
As the cloth, for example, polyester such as PET, cotton, acrylic, felt, non-woven fabric, or the like can be used.
As the cork, one obtained by mixing a cork material and a binder and molding it can be used. Corkwood is obtained by stripping and crushing the bark of the cork oak. Examples of binders include urethane resins, epoxy resins, polyethylene resins, phenol resins, rubbers (natural rubbers, synthetic rubbers), and the like. Urethane resins and epoxy resins are particularly preferred as binders. It should be noted that the liquid absorption index can be increased by increasing the blending amount of the binder.
Examples of inorganic minerals that can be used include stone, glass, calcium carbonate, gypsum, diatomaceous earth, and ceramics.
Examples of charcoal include charcoal, bamboo charcoal, and flower charcoal.
As the plant stem, for example, rattan, rush, or the like can be used.
As the plant branch, for example, a willow branch or the like can be used.

Moreover, the volatilization body may be comprised from multiple types of material. Examples of the multiple types of materials for the volatile material include synthetic fibers, polyesters such as PET, polyethylene (PE), polypropylene (PP), nylon, and the like, and composites thereof.

The shape of the volatilization body is also not particularly limited, and is appropriately selected while considering the material so as to achieve the desired liquid absorption index. For example, any shape such as rod-like, columnar, cylindrical, spherical, plate-like, and character-like can be adopted. From the viewpoint of volatility, the volatilization body preferably has a rod shape.

Also, the thickness of the volatilization body is not particularly limited, and is appropriately set in consideration of the material so as to achieve the desired liquid absorption index.

Examples of the first volatilization body include PET (stick, cloth), acrylic (core), plant stems such as rattan, and the like. Examples of the second volatilization body include cork, PET (core), and PIM molded products of pulp. Here, the stick is a fiber that is twisted in the longitudinal direction of the volatilization body, the cloth is a fiber that is folded vertically and horizontally, and the core is a fiber that is molded into a rod shape using an adhesive such as resin. means what was done.

The volatilization amount ratio between the first volatilization body and the second volatilization body is preferably 6:1 to 1:9, more preferably 4:1 to 1:4, and even more preferably 2:1 to 1:2 on a mass basis. . Here, the vaporization amount means the vaporization amount (g/day) of the perfume per day (24 hours) at 25° C. and 40 to 60% RH, and can be measured by weight measurement over time.

The amount of volatilization of the volatilized material varies depending on the material, composition, size, shape, basis weight (density), fiber length, fiber direction, etc. of the volatilized material, as well as the liquid absorption index above. When it is allowed to evaporate, it varies depending on the length and surface area of the volatilized body that is not immersed in the perfume, and by appropriately setting and selecting these, it is possible to obtain a volatilized body having the desired amount of volatilization. For example, when PET fibers are used, the volatilization amount can be increased by reducing the basis weight. When cork is used, the volatilization amount can be increased by reducing the grain size of the cork material. The surface area can also be adjusted by increasing or decreasing the number of volatilizers used to obtain the desired amount of volatilization.

A volatilizer of one embodiment of the present invention includes a perfume and a volatilizing body, and is arranged so that at least a part of the volatilizing body comes into contact with the perfume. As shown in FIG. 1 , the volatilizer 10 of the present invention may include a container 13 that accommodates a part of the perfume 11 and the volatilization body 12 . The container 13 has, for example, an opening at the top. The volatilization body 12 may be inserted into the container 13 so that the tip protrudes from the opening as shown in FIG. The inserted volatilization body 12 comes into contact with the fragrance 11 contained in the container 13, takes the fragrance inside the volatilization body, sucks it up to the outside of the container 13, and volatilizes the aromatic component.

The shape of the container is not particularly limited as long as it allows the volatilization body to be inserted as described above and can accommodate the perfume. The material of the container is also not particularly limited, and examples thereof include plastic, glass, pottery, and metal.
The volatilization device of the present invention may be in a form that does not include a container.

The present invention will be further described below based on specific test examples, but the present invention is not limited to the following examples.

<Measurement of liquid absorption index>
In this test, the liquid absorption index represented by the following formula (I) was determined for various volatile substances. As the volatilization material, those shown in Table 1, which will be described later, were used.
Formula (I): liquid absorption index = liquid absorption time (seconds) of an isoparaffinic solvent having a carbon number of 10 to 16 and a vapor pressure of 0.05 kPa or less (20 ° C.) / 2 mass% POE decyl ether (E.O. 10 mol ) solution absorption time (seconds)

The absorption time of an isoparaffin-based solvent having 10 to 16 carbon atoms and a vapor pressure of 0.05 kPa or less (20° C.) and a 2% by mass POE decyl ether (E.O. 10 mol) aqueous solution in the above formula (I) is as follows. measured as IP Solvent 2028 (manufactured by Idemitsu Kosan Co., Ltd.) was used as the isoparaffin-based solvent, and Fine Surf D1310 (manufactured by Aoki Yushi Kogyo Co., Ltd.) was used as the POE decyl ether.

1. First, using a capillary (made of glass, manufactured by Fuji Rika Kogyo Co., Ltd.) of (outer diameter) 1.5 mm x (inner diameter) 1.1 mm x (height) 75 mm, the above isoparaffin-based solvent or the above decyl ether aqueous solution was poured to a height of 5 cm. sucked up to
2. Next, the tip of the capillary is brought into contact with the volatilized body, and the volatilized body starts to absorb the isoparaffinic solvent or the aqueous decyl ether solution. The time to complete absorption was measured. This time was defined as the absorption time of the isoparaffinic solvent or the decyl ether aqueous solution.
Among the volatile bodies, for PET sticks, acrylic cores, rattan, PET cores, corks, and PIM molded products, the area of the cross section perpendicular to the longitudinal direction (liquid absorption direction) of the volatile bodies is larger than the area of the tip of the capillary. Since it was large, the tip of the capillary was brought into contact with the tip of the volatilization body in the longitudinal direction to absorb the liquid. In addition, for cloth and paper among the volatile bodies, the area of the cross section perpendicular to the longitudinal direction (liquid absorption direction) of the volatile body is smaller than the area of the tip of the capillary, so the surface near the end in the longitudinal direction of the volatile body The tip was brought into contact with the top to absorb the liquid.
3. The above test was performed 10 times for each volatile substance, and the average value of the absorption time (seconds) and the absorption index (formula (I)) of the isoparaffin-based solvent and decyl ether aqueous solution are shown in Table 1 below. Incidentally, when the absorption time of the isoparaffin-based solvent or the aqueous decyl ether solution was not absorbed within 60 seconds, it was described as "60" in Table 1.

The cork in Table 1 was obtained by stirring cork and urethane resin in a ribbon mixer, molding the resulting mixture by compression molding, cutting it into a plate shape, and punching it out.

<Comparison of liquid absorption times of isoparaffin-based solvents>
In this test, various isoparaffinic solvents having a carbon number within the range of 10 to 16 were absorbed into various volatilized substances, and their absorption times were compared.
The "PET stick", "rattan", "PET core", and "cork" described in Table 1 above were used as volatilization materials.
As isoparaffin-based solvents having 10 to 16 carbon atoms, IP Solvent 2028 (manufactured by Idemitsu Kosan Co., Ltd., vapor pressure 0.04 kPa (20 ° C.)), which is a mixture of isoparaffins having 10 to 16 carbon atoms, and C 11 to 16 A mixture of isoparaffins, Isoper M (ExonMobil, vapor pressure 0.011 kPa (20° C.)) was used.
Absorption of various isoparaffin-based solvents in each volatilized material was performed by the same method as the measurement of the absorption index. This test was performed 10 times for each sample, and the average values are shown in Table 2 below.

From the results in Table 2, for any volatilized substance, when IP Solvent 2028, which is a mixture of isoparaffins with 10 to 16 carbon atoms, is absorbed, and IP Solvent 2028, which is a mixture of isoparaffins with 11 to 16 carbon atoms, is absorbed. The liquid absorption time was the same as when the liquid was absorbed. From this result, when determining the liquid absorption index of the above formula (I), it is possible to use an isoparaffinic solvent having a vapor pressure of 0.05 kPa or less (20° C.) and a carbon number within the range of 10 to 16. have understood.

<Scent sensory test (1-1)>
In this test, volatilizers were prepared using various volatilizers whose liquid absorption index was obtained in the above test, and a sensory test (1-1) of scent was performed.
First, perfumes having formulations shown in Table 3 below were prepared.

50 mL of the fragrance prepared above was filled in two sample bottles (capacity 100 mL) each having an opening at the top. After that, the bottle was covered with aluminum foil, and the tip of each volatilized body shown in Table 4 was in contact with the perfume, and each volatilized body was placed in the bottle to obtain Sample 1 and Sample 2, respectively.
In addition, each of the above bottles contains two volatilized bodies, and as shown in Table 4, two of one type of volatilized body in sample 1 and two or two types of one type of volatilized body in sample 2. One volatile material was used.

After the specimens 1 and 2 were allowed to stand overnight, three trained expert panelists smelled each specimen and performed a sensory evaluation. The sensory evaluation was performed based on the following evaluation criteria for the difference in scent between the samples 1 and 2, and the average value of the three people was calculated.

Regarding Example 1, first, according to Example 1-1, the volatilized body in specimen 1 has a liquid absorption index of 0.65 or more, and the volatilized body in specimen 2 has a liquid absorption index of less than 0.65. It was confirmed that the difference in fragrance between the two was clearly perceived. In Examples 1-2 and 1-3, since the sample 2 includes a volatilized body having a liquid absorption index of 0.65 or more and a volatilized body having a liquid absorption index of less than 0.65, one type of As a result, a difference in scent between the samples can be felt between the sample 1 containing only the volatilized substance. The same was true for Examples 2-4.
That is, in Example 1, according to Example 1-1, the fragrance of sample 1 (PET stick) (assumed to be fragrance A) and the fragrance of sample 2 (cork) (assumed to be fragrance B) are different, Different scent notes, namely, scent notes A and B, were able to be expressed in the samples 1 and 2. Also in Examples 1-2 and 1-3, the scent of sample 1 (PET stick or cork) (scent note A or scent note B) and the scent of sample 2 (PET stick and cork) (smell note C) Since they are different, in the sample 2, the fragrance tone C different from both the fragrance tone A and the fragrance tone B could be expressed. In this way, in Example 1, the variation of the fragrance tone that can be expressed is increased, and various fragrance tones can be expressed. The same was true for Examples 2-4.
On the other hand, with respect to Comparative Example 1, first, according to Comparative Example 1-1, both the volatilized substances in Samples 1 and 2 had a liquid absorption index of 0.65 or more, so that only a slight difference in scent between the samples was felt. Confirmed not. In Comparative Examples 1-2 and 1-3, both of the two types of volatilized bodies in the specimen 2 have a liquid absorption index of 0.65 or more, so between the specimen 1 containing only one type of volatilized body The result was that the difference in scent between the samples was not felt so much. The same applies to Comparative Examples 2 and 3.
That is, in Comparative Example 1, first, according to Comparative Example 1-1, the difference between the scent of sample 1 (PET stick) (assumed to be fragrance A) and the scent of sample 2 (acrylic core) (assumed to be fragrance A') is Since the sample 1 and the sample 2 are small, only similar scent notes of scent notes A and A' can be expressed. Also in Comparative Examples 1-2 and 1-3, the scent of sample 1 (PET stick or acrylic core) (scent note A or scent note A') and the scent of sample 2 (PET stick and acrylic core) (scent note A'') is small, the specimen 2 can express only the fragrance A'' which is similar to the fragrance A or A'. Thus, in Comparative Example 1, only similar fragrance tones can be expressed, and various fragrance tones cannot be expressed. The same was true for Comparative Examples 2 and 3.

Also, with regard to aroma quality, in Examples 1-2, 1-3, 2-2, 2-3, 3-2, 3-3, 4-2, and 4-3, types from two types of volatile substances It was a deep scent with a variety of favorable effects, which was a combination of different scents. On the other hand, in Comparative Examples 1-2, 1-3, 2-2, 2-3, 3-2 and 3-3, two types of volatilizers were used, but the fragrance was monotonous.

From the above results, by including at least a volatilization medium with a liquid absorption index of 0.65 or more and a volatilization medium with a liquid absorption index of less than 0.65, it was possible to realize various expression of fragrance tone.

First, perfumes having the same composition as shown in Table 3 above were prepared. 50 mL of the prepared perfume was filled into two sample bottles (capacity 100 mL) each having an opening at the top. After that, cover with aluminum foil, put each volatilized body in the bottle so that the tip of each volatilized body shown in Table 7 is in contact with the perfume, and obtain Sample 1 and Sample 2, respectively. In addition, two volatilized bodies were put in each of the above bottles, and as shown in Table 7, two of one type of volatilized bodies were used in sample 1, and two types of volatilized bodies were used in sample 2.
In addition, the volatilization amount ratio of the PET stick and the cork was adjusted by changing the length of the volatilization body in the longitudinal direction as shown in Table 6 and changing the length of the volatilization body coming out of the perfume. Table 6 shows the relationship between the combination of PET stick and cork and the volatilization ratio.
The volatilization amount of the PET stick and cork means the volatilization amount (g/day) of the fragrance per day (24 hours) at 25° C. and 40 to 60% RH, and was measured by weight measurement over time. .

After the specimens 1 and 2 were allowed to stand overnight, three trained expert panelists smelled each specimen and performed a sensory evaluation. The sensory evaluation was performed based on the following evaluation criteria for the difference in scent between the samples 1 and 2, and the average value of the three people was calculated.
3: Perceives a clear difference in fragrance 2: Perceives a difference in fragrance easily 1: Perceives a slight difference in fragrance 0: Perceives no difference in fragrance The results are shown in Table 7 below.

In the sample 2 of Examples 5 to 12, the volatilization amount ratio of the volatilized body with a liquid absorption index of 0.65 or more and the volatilized body with a liquid absorption index of less than 0.65 is within the range of 6: 1 to 1: 9 Therefore, the difference in scent between the samples was felt to be large between the sample 1 containing only one type of volatilized substance. That is, the sample 2 can express a scent tone different from that of the sample 1, which contains only one type of volatile substance, and the variation of the scent tone that can be expressed increases, and various scent tones can be expressed.

<Scent sensory test (2-2)>
The same test as the sensory test of scent (2-1) was performed, except that the sensory evaluation was performed by 10 trained expert panelists. Table 8 below shows the results of calculating the average value of 10 expert panelists.

When sensory evaluation was performed by 10 expert panelists, the results were similar to those of the sensory test (2-1) above. That is, since the volatilization amount ratio of the volatilized body with a liquid absorption index of 0.65 or more and the volatilized body with a liquid absorption index of less than 0.65 is within the range of 6: 1 to 1: 9, one type of volatilized body As a result, the difference in scent between the samples was felt to be large between the sample 1 containing only the sample.
