Description

  The present invention relates to an aromatic liquid composition for an aromatic deodorizer. Furthermore, this invention relates to the aroma deodorizer using the said aromatic liquid composition.

  In order to eliminate the discomfort due to the odor of indoor spaces such as homes and cars, and to create a comfortable space, fragrances that can exert a fragrance effect by volatilizing the fragrance naturally are widely used.

  On the other hand, such a fragrance has a drawback that even if the indoor space can be filled with fragrance due to the fragrance effect due to the evaporation of the fragrance, the odor cannot be eliminated if the space has a bad odor.

  Conventionally, a method of removing bad odor in a space by using activated carbon to adsorb and deodorize the bad odor has been widely used.

  Therefore, if the fragrance effect by the fragrance and the deodorization effect by the activated carbon can be combined effectively, it becomes possible to deodorize the odor from the indoor space and fill the space with the fragrance, and the fragrance has both the fragrance function and the deodorization function. Provision of a deodorizer can be realized.

  However, as a result of research by the present inventors, the liquid fragrance contains a linear surfactant (mainly higher alcohol) in order to dissolve the fragrance in the fragrance. It has been found that the activated carbon has a great adverse effect on the deodorizing ability. Specifically, if a commonly used fragrance containing a surfactant and activated carbon coexist, the surfactant will be adsorbed on the activated carbon, resulting in a problem that the deodorizing ability of the activated carbon is reduced. I understood.

Until now, since such technical problems have not been solved, an aroma deodorizer capable of effectively exhibiting the aroma function by the fragrance and the deodorization function by the activated carbon has not been developed yet.

  Accordingly, an object of the present invention is to solve the above-described problems of the prior art. Specifically, an object of the present invention is to provide an aromatic liquid composition that can exhibit an excellent fragrance effect without impairing the deodorizing function of activated carbon when used in the presence of activated carbon. .

  It is another object of the present invention to provide an aroma deodorizer having both excellent aroma and deodorizing functions.

  As a result of intensive studies to solve the above-mentioned problems, the present inventors have found that an aromatic liquid composition is blended with an ethylene oxide addition type surfactant having a linear branched structure or a cyclic structure together with a fragrance and having a molecular weight of 800 or more.

Moreover, it discovered that the aroma deodorizer containing the said aromatic liquid composition and activated carbon in combination was excellent in both the effect of aroma and a deodorizing. The present invention has been completed by further studies based on these findings.

  The wicking volatilization member 6 includes a wicking portion 6a that sucks up the aromatic liquid 4 and a volatile portion 6b. The whole wicking volatilization member 6 is made of a material excellent in the wicking and volatilization effect of the fragrance liquid 4, and is mainly a fibrous material such as natural fiber such as plant fiber or pulp, man-made fiber or mixed fiber thereof. It consists of Moreover, the shape of the suction volatilization member 6 is strip | belt shape, and the width of the suction part 6a is narrower than the volatilization part 6b. The reason why the suction portion 6a is narrow is that the suction portion 6a is folded when not in use and extended when in use, as shown in FIG. 1 (a). Moreover, the width of the volatilization part 6b is wide so that the aromatic liquid 4 can be easily volatilized.

  As shown in FIG. 2B, the volatilization part 6b is composed of a thin covering layer 11 on the surface (upper surface and lower surface in FIG. 2B) and an internal fiber layer 12, and the fiber layer 12 is Granular activated carbon 13 is included. The covering layer 11 is a thin rayon, and is provided to hold the fiber layer 12 so that the fibrous material and the granular activated carbon 13 constituting the inner fiber layer 12 do not fall off from the surface. The fiber layer 12 is mixed in the above-described fibrous material, and the entire shape is held in a non-woven fabric by heat-fusible fibers that function as a binder. A method for forming the fiber layer 12 including the granular activated carbon 13 will be described in detail later.

  The activated carbon 13 is dispersed in the fiber layer 12, and the action of the activated carbon 13 improves the deodorizing effect of the fragrance device 1. That is, the fragrance of the fragrance | flavor melt | dissolved in the aromatic liquid 4 spreads in the air from the volatilization part 6b, and the malodor component causing the malodor in the air is adsorbed by the activated carbon 13. Therefore, in addition to the aroma deodorizing effect by the fragrance, a strong deodorizing effect by the activated carbon 13 is exhibited.

  The appliance for the fragrance device 1 shown in FIG. 1 is merely an example, and the appliance to which the wicking volatilization members 6, 61, 62 shown in FIGS. 2 and 3 are applied is limited to this type. is not. For example, an instrument disclosed in Japanese Utility Model Publication No. Sho 42-21280, that is, one end of a wicking member attached to the head of a support made of an elastic material such as steel wire, Put the volatilization member in the container, so that the other end of the wicking volatilization member is immersed in the aromatic liquid, and the instrument configured to allow the volatilization part to be taken in and out of the container by moving the support up and down, etc. It can be applied to various instruments that use the aromatic liquid 4 and that use a wicking volatilization member.

  By using the fragrance composition of the present invention in the fragrance deodorizer 1 configured as described above, an excellent fragrance effect and deodorization effect can be obtained.

  The activated carbon 13 used in the fragrance deodorizer is not particularly limited as long as it can adsorb a substance that causes bad odor, but it can be suitably used in the properties described below.

  The shape of the activated carbon 13 is not particularly limited, but a granular one is preferable. In particular, granular particles having an average particle diameter of 150 to 850 μm (100 to 18.5 mesh) are preferable, and granular particles having an average particle diameter of 210 to 620 μm (70 to 20 mesh) are more preferable (however, And 95% by mass or more under the sieve). This is because if the particles are too fine, they will easily fall off from the fiber layer, and if the particles are too large, the surface area of the activated carbon will be small, so that a sufficient deodorizing effect may not be obtained.

  As such activated carbon, for example, commercially available products such as trade name “GW26 / 70” (manufactured by Kuraray Chemical Co., Ltd.) and trade name “GW32 / 60” (manufactured by Kuraray Chemical Co., Ltd.) can be used.

  In addition, the swelling rate of the fiber layer 12 used in the fragrance deodorizer is preferably in the range of 0 to 15%, and more preferably in the range of 0 to 7%. If the swelling rate is too high, the activated carbon in the fiber layer tends to fall off. On the other hand, when the swelling rate is low, the activated carbon 13 is difficult to drop off, but the volatilization effect may be low depending on the type of the aromatic liquid 4.

In addition, the swelling rate as used in this specification is one parameter | index showing the ease of dropping off of the activated carbon 13, and the measuring method is as follows.
(1) Prepare three samples of the volatilization part (including the coating layer 11) 6b. Although the size is arbitrary, the size of one side is preferably about 50 mm.
(2) The thickness t _{0 of the} sample is measured with a constant pressure thickness measuring machine manufactured by Mitutoyo. The load is 7.0 g / m ² .
(3) Immerse the sample in distilled water for 30 minutes.
(4) Remove the sample from the distilled water and measure the thickness t ₁ of the sample under the same conditions as in (2) above.
(5) The swelling ratio R _S (%) is obtained by R _S = {(t ₁ −t ₀ ) / t ₀ } × 100.

  The reason why the falling rate of the activated carbon 13 changes depending on the swelling rate is as follows. As described above, the fiber layer 12 is held in a non-woven shape by the heat-fusible fiber whose fibrous material is a binder. When the ratio of the heat-fusible fibers in the fiber layer 12 is large, the fiber layer 12 is tightly bonded to the entire fibrous material, so that the activated carbon 13 is firmly held in the fiber layer 12. Therefore, it is hard to fall off. In addition, when immersed in a liquid, the fibrous material is strongly adhered, and thus hardly swells. If the swelling rate is low, it is conceivable that the volatility of the aromatic liquid 4 in the volatilization part 6b becomes low and the deodorizing effect of the activated carbon 13 becomes small. Therefore, it is desirable that the swelling ratio is moderate. On the other hand, when the amount of heat-fusible fibers is small, the converse is true, and instead of increasing the swelling rate, the tendency of the activated carbon 13 to drop off increases.

  Therefore, in order to suppress the falling off of the activated carbon 13 and to ensure the volatility of the volatilization part 6a, it is preferable to select an appropriate swelling rate. However, the appropriate swelling rate varies depending on the size (particle size) of the activated carbon, the type and characteristics of the fibrous material constituting the fiber layer 12, the characteristics of the heat-fusible fiber as the binder, etc. It is preferable to select according to the above conditions. As an example, the swelling rate at which the ratio of the activated carbon 13 falling off is low is in the range of 0 to 15%.

  The ratio of the activated carbon 13 in the fiber layer 12 is preferably in the range of 10 to 50% by weight with respect to the total weight of the fiber layer 12. If the ratio of the activated carbon 13 is too large, the activated carbon 13 that falls off increases, and if the ratio is too small, the deodorizing effect is not sufficiently exhibited. However, since the preferable ratio of the activated carbon 13 varies depending on the swelling rate, the size of the activated carbon 13 and the like, it is desirable to select the ratio according to the conditions of the respective fiber layers 12.

  Activated carbon used in the fragrance deodorizer may be contained in the entire suction portion 6a of the suction volatilization member 6 (see FIG. 2). That is, the suction part 6a may also have a cross-sectional structure similar to that shown in FIG. In the case of this type, the entire wicking volatilization member 6 can be made of the same material, so that the manufacture is easy.

  However, the suction part 6a is a part immersed in the aromatic liquid 4, and is a part which is not exposed in the air. Therefore, since it is not necessary to have a deodorizing action, it is a portion that does not need to contain activated carbon 13. Therefore, you may comprise the suction part 6a with the material which has the wicking property which does not contain activated carbon. For example, a fibrous material similar to the volatilization part 6b containing the activated carbon 13 or a sponge material made of a synthetic resin such as a non-woven fabric, a knitted fabric, or foamed urethane that is widely used so that the sucked liquid permeates the volatilization part 6b. It may be joined to the substrate.

  Further, as shown in FIG. 1A, the suction part 6a is pulled up in a folded state in a state before use, that is, in a state where the cap 7 seals the aromatic liquid container 3. In the state, it is better that the shape tends to be extended as shown in FIG. Therefore, it is preferable that the sucking portion 6b has a shape that extends from a folded shape, or vice versa, that is, a shape that is easily changeable, that is, has high flexibility.

  FIG. 3 is a partially enlarged perspective view showing a suction part according to another embodiment of the suction volatilization member 6, and (a) is an example in which a weak part is provided at a substantially right angle in the length direction on the suction part. b) is an example in which a weak part is provided in the longitudinal direction of the suction part. As shown in FIG. 3A, in the case of the wicking volatilization member 61, a weak portion is formed on both sides of the wicking portion 61a with a predetermined interval and in a direction substantially perpendicular to the length direction. A notch 61c is provided. By providing this weak part 61c, the flexibility of the suction part 61a can be remarkably improved.

  Further, as shown in FIG. 3B, in the case of the wicking volatilization member 62, a slit 62c which is a weak portion is provided in the length direction of the wicking portion 62a, and the wicking portion 62a is a thin string. It is in the shape. Thus, the flexibility of the suction part 61a can be remarkably improved by making the suction part 62a into a thin string shape.

  The manufacturing method of the fiber layer 12 containing the activated carbon 13 of the suction volatilization member 6, 61, 62 is as follows. The main fibers constituting the fiber layer 12 are natural fibers such as plant fibers and pulp, artificial fibers, or mixed fibers thereof as described above. First, these fibrous materials are crushed. The heat-fusible fiber is mixed as uniformly as possible with this fibrous material, and the activated carbon 13 is further mixed as uniformly as possible. With this mixture, for example, a sheet-like web is formed, and a thin rayon for the coating layer 11 is overlapped on both sides thereof. Next, the web sandwiched by the coating layer 11 is heated at a temperature higher than the melting temperature of the heat-fusible fiber to a temperature at which other materials are not damaged by heat. By this heating, the fiber layer 12 of the suction volatilization member 6, 61, 62 in which the shape of the fiber layer 12 is maintained can be formed.

  As the heat-fusible fiber, for example, high-density polyethylene fiber (melting point: about 131 ° C.), polypropylene fiber, polyvinyl chloride fiber, or the like can be used. As described above, the mixing ratio of the fibrous material and the heat-fusible fiber affects the swelling rate of the wicking volatilization member 6 (or the volatilization portion 6a), so the mixing ratio is determined based on the swelling rate. It is good. Generally, it is preferable to select from a range of about 98 to 60% by mass of the fibrous material and about 2 to 40% by mass of the heat-fusible fiber.

  As the binder, a liquid binder other than the heat-fusible fiber can be used. However, in the method in which a liquid binder is sprayed on the fibrous material and dried and adhered, the binder covers the surface of the activated carbon 13 and the deodorizing function of the activated carbon may be reduced. Therefore, a binder that is solid at room temperature is suitable as the binder. The heat-fusible fiber is a kind of solid binder, and a binder other than the heat-fusible fiber may be used as long as it has a similar adhesive function.

  One of the uniform mixing methods of the granular activated carbon 13 and the fibrous material is the following method. First, loosen the fibrous material and spread it to a uniform thickness as much as possible. Next, activated carbon is sprayed thereon. On top of that, a thin fibrous material is further laminated. By repeating this until the predetermined thickness is reached, the fiber layer 12 in which the activated carbon 13 is uniformly dispersed can be formed.

  Furthermore, this invention provides the aroma deodorizer containing the said aromatic liquid composition and activated carbon. The fragrance deodorizer of the present invention uses the above “fragrance liquid composition” as the fragrance liquid of the “fragrance deodorizer containing activated carbon”.

  The surfactant itself used in the fragrance composition of the present invention does not adsorb on activated carbon. Therefore, even if the fragrance is dissolved by forming micelles in the fragrance liquid composition, or even if the surfactant is present alone after the fragrance is volatilized, the interface The activator does not adsorb with activated carbon. In particular, normally used linear surfactants are adsorbed on activated carbon and reduce the deodorizing function of activated carbon, but the surfactant used in the present invention is difficult to adsorb on activated carbon, The function of activated carbon can be effectively exhibited. Therefore, according to the fragrance composition of the present invention, even when used in the presence of activated carbon, an excellent aroma effect can be achieved without impairing the deodorizing function of the activated carbon.

  Moreover, the aroma deodorizer of this invention can show | play the outstanding aroma effect by an aromatic liquid composition, and the outstanding deodorizing effect by activated carbon. Therefore, according to the fragrance deodorizer of the present invention, it is possible to create a comfortable space environment by removing malodor from the indoor space such as kitchen, toilet, warehouse, etc. and filling it with the desired fragrance.

  EXAMPLES Hereinafter, although a test example and an Example are given and this invention is demonstrated, this invention is not limited to these Examples.

Test Example 1 Activated carbon adsorption test In order to evaluate the adsorptivity of the surfactants shown in Table 1 below to activated carbon, the following tests were conducted.

Each surfactant shown in Table 1 was added so that the concentration of the surfactant in distilled water was 1% by weight. Subsequently, granular activated carbon [raw material: coconut husk, average pore size: 1 nm, specific surface area: about 1000 m ² / g, packing density: 0.48 to 0.56 g / ml, particle size distribution: 20 to 10 ml of the surfactant-containing aqueous solution. 70 MESH (95% or more); trade name “GW26 / 70”, manufactured by Kuraray Chemical Co., Ltd.] 0.1 g was added, and the mixture was shaken at 25 ° C. for 16 hours. Thereafter, the amount of the surfactant remaining in the aqueous solution was measured using a total organic carbon meter. The ratio of the reduced amount of surfactant to the amount of surfactant in the aqueous solution before addition of activated carbon was calculated as the adsorption rate (%).

  The obtained results are also shown in Table 1. As can be seen from Table 1, it was found that polyoxyethylene styryl phenyl ether, polyoxyethylene hydrogenated castor oil ether, polyoxyethylene polyoxyethylene glycol and polyoxyethylene coconut oil fatty acid sorbitan are hardly adsorbed on activated carbon. On the other hand, it was found that a surfactant having a linear structure such as polyoxyethylene lauryl ether is adsorbed on the activated carbon at a high rate.

Test Example 2-9 Activated Carbon Deodorizing Effect Confirmation Test In order to examine the influence of the aromatic liquid composition of the present invention on the deodorizing effect of activated carbon, the following test was performed.

  A surfactant-containing aqueous solution containing 10% by weight of the surfactants shown in Table 2 below in distilled water was prepared. In a glass container containing 100 ml of the surfactant-containing aqueous solution, granular activated carbon (trade name “GW26 / 70”, manufactured by Kuraray Chemical Co., Ltd.) having an average pore diameter of 1 nm or activated carbon (trade name “GW32 / 60 ”(manufactured by Kuraray Chemical Co., Ltd.) was added, the container was sealed, and shaken at 25 ° C. for 16 hours. After shaking, the activated carbon was separated using filter paper, and the recovered activated carbon was dried by heating at 25 ° C. for 3 hours (Test Example 2-9, Comparative Test Examples 1 and 2). For comparison, activated carbon was obtained by the same treatment as above except that no surfactant was used (Comparative Test Example 3-4). 0.1 g of the activated carbon thus dried was placed in a 300 ml container, and methyl mercaptan was further sealed in the container to a concentration of 400 ppm and left at 25 ° C. for 1 hour. Next, the methyl mercaptan concentration in the container was measured using a gas detector manufactured by Gastec. From the measured value, the ratio of the decrease amount of methyl mercaptan after the treatment relative to the initial methyl mercaptan amount in the container was calculated as the deodorization rate (%).

  The obtained results are also shown in Table 2. As can be seen from Table 2, activated carbon (Test Examples 2 to 9) coexisting with polyoxyethylene styryl phenyl ether is activated carbon (Comparative Test Examples 1 and 2) coexisting with polyoxyethylene lauryl ether. It was revealed that the deodorizing ability was maintained at a high value as compared to). In particular, the effect was remarkably recognized when activated carbon having an average pore diameter of 1 nm was used (see Test Example 2).

Example 1-2 Adsorption Suppression Confirmation Test In order to examine the influence of the aromatic liquid composition of the present invention on the adsorption of a fragrance to activated carbon, the following test was conducted.

Aroma liquids having the formulations shown in Table 3 below were prepared (Examples 1 and 2). In a test tube containing 10 g of this aromatic liquid composition, granular activated carbon (raw material: coconut shell, average pore diameter: 1 nm, specific surface area: about 1000 m ² / g, packing density: 0.48 to 0.56 g / ml, particle size distribution) : 20 to 70 MESH (95% or more); 0.1 g of a trade name “GW26 / 70” (manufactured by Kuraray Chemical Co., Ltd.) was added and the test tube was sealed, followed by stirring at 25 ° C. for 16 hours. Next, the activated carbon and the aromatic liquid were separated, and the fragrance remaining in the aromatic liquid was quantified by gas chromatography. From the comparison between the amount of fragrance in the fragrance before mixing with activated carbon and the amount of fragrance in the fragrance after the treatment, the ratio (adsorption rate) (%) of the fragrance in the fragrance was adsorbed on the activated carbon was calculated. The quantitative determination of the fragrance was performed for 15 fragrance components (see Table 4 below), which are representative components in the used fragrance. Further, the fragrance component was quantified by gas chromatography using phenylethyl alcohol as an internal standard.

  For comparison, the same test was performed using an aromatic liquid not containing 3-methoxy-3-methyl-1-butanol (see Comparative Example 1, Table 3).

  The obtained results are also shown in Table 4. From the results of this test, it was found that the fragrance liquids of Examples 1 and 2 suppressed the adsorption of the fragrance to activated carbon as compared with Comparative Example 1. In particular, an aromatic liquid containing 3-methoxy-3-methyl-1-butanol as a surfactant with polyoxyethylene styryl phenyl ether (trade name “Penerol SP-18”, manufactured by Matsumoto Yushi Seiyaku Co., Ltd.) (Example 2) ), It was found that the adsorption of the fragrance on activated carbon was significantly suppressed.

Reference Test Example 1 Adsorption characteristics of fragrance components on activated carbon In order to examine the adsorption characteristics of various fragrance components on activated carbon, the following tests were conducted using the fragrance components shown in (1) to (75) of Tables 5 to 13 below. Went.

78 test tubes were prepared, 9.9 ml of ethanol was added to these test tubes, and then the fragrance components shown in (1) to (75) of Tables 5 to 13 were added to each test tube. A fragrance solution containing about 1% fragrance components (containing about 1% fragrance components) (57 types in total) was prepared. 10 ml of each fragrance solution was charged with activated carbon (raw material: coconut shell, average pore size: 1 nm, specific surface area: about 1000 m ² / g, packing density: 0.48 to 0.56 g / ml, particle size distribution: 20 to 70 MESH (95% Above); trade name “GW26 / 70” (manufactured by Kuraray Chemical Co., Ltd.) 0.1 g was added and the test tube was sealed, followed by shaking at 25 ° C. for 16 hours. Next, the activated carbon and the fragrance solution were separated, and the amount of the fragrance component remaining in the fragrance solution was quantified by gas chromatography. From the comparison between the amount of the fragrance component in the fragrance solution before mixing with the activated carbon and the amount of the fragrance component in the fragrance solution after the above treatment, the ratio (adsorption rate) (%) of the fragrance component in the fragrance solution adsorbed on the activated carbon was calculated. The quantitative determination of the fragrance component by gas chromatography was performed using phenylethyl alcohol as an internal standard.

  The results obtained are shown in Table 5-13. From this test result, it was found that there is a correlation between the structure of the fragrance component and the activated carbon adsorption characteristics of the fragrance component. Therefore, it was suggested that a fragrance composition capable of producing an excellent fragrance effect even in the presence of activated carbon can be prepared by selecting a fragrance component having a structure that is difficult to adsorb on activated carbon with reference to the test results.

  In particular, in this test, it was confirmed that the fragrance component having an adsorption rate of 30% or less has a sufficient fragrance effect even in the presence of activated carbon. Therefore, in the fragrance composition of the present invention, a fragrance liquid having a more excellent fragrance effect in the presence of activated carbon by selecting and using a fragrance component having an adsorption rate of 30% or less in this test as the fragrance component. It has been found that a composition can be prepared.
