Definitions

- odor removing methods There are many odor removing methods. For example, there are methods which use a material to block a receptor of an olfactory organ, methods whereby an odor material is oxidized, methods of removing odor-generating bacteria, methods that use a strong fragrant material, and methods of capturing an odor molecule using a porous material such as zeolite, silica or the like. Among these methods, the method of capturing an odor molecule using a porous material is efficient, but it is difficult to incorporate and apply this method in the form of spray.

Description
The present invention relates to a composition for removing an odor, the composition including cucurbituril, and a method of preparing the same.
There are many odor removing methods. For example, there are methods which use a material to block a receptor of an olfactory organ, methods whereby an odor material is oxidized, methods of removing odor-generating bacteria, methods that use a strong fragrant material, and methods of capturing an odor molecule using a porous material such as zeolite, silica or the like. Among these methods, the method of capturing an odor molecule using a porous material is efficient, but it is difficult to incorporate and apply this method in the form of spray. Therefore, recently, macrocylclic molecules that have water-soluble properties and can capture odor molecules have attracted considerable attention. Cyclodextrin is a typical example of such macrocyclic molecules. Cyclodextrin was discovered in 1891 and has been actively researched ever since it was discovered that cyclodextrin reacts with several compounds to form inclusion complexes. Thus, cyclodextrin has been utilized in various fields such as food manufacture, medicine and the like.
Meanwhile, cucurbituril is a material which was first reported by R. Behrend, E. Meyer and F. Rusche in 1905. In 1981, W. Mock and others discovered that this material is a macrocyclic compound composed of six monomers and having a chemical formula of C36H36N24O12, and they observed the structure thereof using X-ray diffraction (J. Am. Chem. Soc.1981, 103, 7367). They called this compound "cucurbit[6]uril". Later, in 2000, K. Kim and others synthesized and separated cucurbit[n]urils n = 5, 7, 8), as homologues of cucurbit[6]uril, as well as cucurbit[6]uril, by improving a conventional method of synthesizing cucurbit[6]uril, and they observed their respective structures using X-ray diffraction (J. Am. Chem. Soc. 2000, 122, 540). Meanwhile, International Patent Application Publication No. WO 00/68232 discloses cucurbit[n]uril which is represented by Chemical Formula below:
[Chemical Formula]
wherein n is an integer of 4 to 12.
Each of the cucurbituril derivatives is a compound composed of glycoluril monomers having no substituent group (KR-A-10-2007-0073225).
It is proposed in the prior patent of the present inventors that cucurbituril can be used as a bad odor remover or the like because it has a structure which can be bonded with an organic compound. However, experiments that may support this possibility have never been carried out by the present inventors or other researchers. Thus, the present inventors experimentally found that cucurbituril can fulfill a function of removing an odor, and the present inventors also found the optimal composition ratio of the complex and the optimal conditions required to exhibit functions. Based on these findings, the present invention was completed.
Accordingly, the present invention has been devised to solve the above-mentioned problems, and an object of the present invention is to provide a composition for removing an odor, the composition including cucurbituril, which can effectively remove odors caused by various kinds of materials.
However, an object to be accomplished by the present invention is not limited to the above-mentioned object, and other objects (not mentioned) will be clearly understood from the following descriptions by those skilled in the art.
In order to accomplish the above object, an aspect of the present invention provides a composition for removing an odor, the composition including a compound represented by Chemical Formula 1 below:
[Chemical Formula 1]
wherein n is an integer of 4 to 20, and X is O, S or NH, and
wherein the composition includes 45 to 100 wt% of the compound of Chemical Formula 1 of n = 7.
The compound of Chemical Formula 1 is cucurbituril.
The composition of the present invention can capture and remove various kinds of odor materials (particularly, ammonium ion-containing bad odor, such as a fishy smell or the like) because cucurbituril can interact with various odor materials using its hydrophobic cavity and both inlets covered with carbonyl groups. Further, since the composition can effectively remove odors from various odor emission materials according to the composition ratio of cucurbituril homologues, it can be made into various products by suitably adjusting the composition ratio of cucurbituril homologues.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.
The present invention provides a composition for removing odor, the composition including a compound represented by Chemical Formula 1 below:
[Chemical Formula 1]
wherein n is an integer of 4 to 20, and X is O, S or NH, and
wherein the composition includes 45 to 100 wt% of the compound of Chemical Formula 1 of n = 7.
The compound of Chemical Formula 1 is cucurbituril.
According to the experiment of the present inventors (refer to Example 1), since the cavity of cucurbit[7]uril, which is the compound of Chemical Formula 1 of n = 7, is most easily bonded with a fragrant material, cucurbit[7]uril is most advantageous in terms of removing an odor. In this case, it is preferred that the ratio of the amount of cucurbit[7]uril to the total amount of cucurbituril be high. However, in order to increase the amount of cucurbit[7]uril at the time of synthesizing cucurbit[7]uril, a process of purifying the synthesized cucurbit[7]uril (crude cucurbit[7]uril) is additionally required, thus decreasing economical efficiency. Therefore, the synthesized crude cucurbit[7]uril itself can be used to remove an odor, and, in this case, the amount of cucurbit[7]uril in the crude cucurbit[7]uril may be 45% to 100% based on the total amount of cucurbituril. The composition may further include cucurbiturils of Chemical Formula 1 of n = 4 to 6 and 8 to 20 in an amount of 0 ~ 35%. Among the cucurbiturils of Chemical Formula 1 of n = 4 to 6 and 8 to 20, cucurbit[6]uril is mostly used. Besides, the composition may further include cucurbiturils of Chemical Formula 1 of n = 4, 5 and 8 to 20 in an amount of 0 ~ 5%.
The crude cucurbit[7]uril is synthesized by a method including the following steps. However, the synthesis method thereof is not limited thereto.
1) Glycoluril 1.05 M (150g) and paraformaldehyde 2.2 M (67g) are mixed with a sufficient amount of HCl (225mL), and this mixture is heated to 85 ~ 90℃ for 18 hours to obtain a cucurbituril solution.
2) H2O (3L) is added to the cucurbituril solution, and then the solution is filtered to obtain a filtrate, and then the filtrate is mixed with methanol (2.4L) to obtain a solid-containing solution.
3) The solid-containing solution is filtered by a filter paper to obtain a solid compound, and then the solid compound is washed with methanol (2L) and dried to obtain crude cucurbit[7]uril.
According to another embodiment of the present invention, the cucurbituril may be dissolved in a buffer. Examples of the buffer may include, but are not limited to, PBS (phosphate buffered saline), Tris-HCl, Tricine, HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid), MOPS (3-(N-morpholino)propanesulfonic acid), SSC (saline sodium citrate), and MES (2-(N-morpholino)ethanesulfonic acid).
The composition of the present invention may further include an additive. In this case, examples of the additive may include, but are not limited to, fragrances such as ethyl butyrate, camphor, menthol, hexanal, eugenol, citronellol, linalool, patchoulol, santalol, phenyl ethyl alcohol, terpineol, vanillin, benzaldehyde, methyl salicylate, isoamyl acetate, d-limonene, L-limonene, α-pinene, 2-hydroxy-p-cymene, methyl acetophenone, and cis-jasmone; and/or solvents such as cyclohexane, hexane, heptane, isooctane, isopentane, pentane, dimethyl ether, diethyl ether, methanol, ethanol, propanol, isopropanol, butanol, acetone and propellants.
The composition of the present invention is very effective at capturing an odor molecule having an amino group or a carboxyl group, but can effectively capture other odor molecules. The odor which can be removed by the composition of the present invention may be emitted from an odor emission material such as onion, garlic, pork, fish, fermented fish, mold, bacteria, body fluids, leather, sewage, industrial wastewater or the like. However, the kinds of the odor emission material are not limited thereto.
The composition of the present invention can remove an odor from an odor emission material by 30% or more, which was measured by an odor measuring device.
Cucurbituril, which is a macrocyclic compound, has a hydrophobic cavity, and has hydrophilic inlets at both sides thereof. Therefore, hydrophobic interaction occurs in the cavity of cucurbituril, and hydrogen bonding, polar interaction, cation-polar interaction and the like occur at the upper and lower inlets thereof at which six carbonyl groups are located, so cucurbituril exhibits inclusion effects using extremely stable noncovalent binding with various kinds of compounds. Particularly, cucurbituril is formed into a complex by extremely stable noncovalent binding with compounds having a functional group such as an amino group, a carboxyl group or the like. Thanks to it having such characteristics, cucurbituril can effectively capture various kinds of odor molecules, and thus cucurbituril can be used a deodorizer which is superior compared to conventional deodorizers.
In Example 1, an odor removing effect was evaluated using a mixture of cucurbituril homologues, and in Examples 2 and 3, the odor removing effect of each cucurbituril was compared to that of a commercially available deodorizer.
The odor removing effects in Examples may be different from each other according to the amount of an odor material, the kind of the odor material and the used portion of the odor material (for example, the degree of odor of onion is different with respect to each portion). The values (Y axis in graph) measured by an odor measuring device used in the experiment are relative values indicating the degree of strength and weakness of odor, so it is difficult to indicate these values as absolute values. Therefore, the comparison of the odor removing effect of each cucurbituril or each deodorizer may be regarded independently.
Hereinafter, the present invention will be described in more detail with reference to the following Examples. However, these Examples are set forth to illustrate the present invention, and the scope of the present invention is not limited thereto.

The solution was sprayed onto odor emission materials such as onion, garlic, pork (pork belly), fish (japanese spanish mackerel), fermented fish (sliced raw skate) and the like to such a degree that each of the odor emission materials was sufficiently impregnated with the solution. After 1 hour, the degree of odor emission was measured using an odor measuring device (COSMOS, XP-329 m). The degree of reduction of odor emission was evaluated by the values measured by the odor measuring device on the basis of that obtained when only PBS buffer was sprayed. The average and standard deviation of the values obtained by testing the same sample three times were calculated and charted. The results thereof are shown in FIGS. 2A, 3A, 4A, 5A and 6A.

In order to compare the odor removing effect of each cucurbituril homologue with that of β-hydroxypropyl cyclodextrin, which is generally used as a deodorizer for textile materials, the following experiment was carried out.
Cucurbit[6]uril (CB[6]), cucurbit[7]uril (CB[7]) and β-hydroxypropyl cyclodextrin (Hy CD) were respectively dissolved in a buffer (PBS, pH 7.2) to obtain a solution (1 w/v %). 1 mL of the solution was sprayed onto odor emission materials such as onion, garlic, pork (pork belly), fish (japanese spanish mackerel), fermented fish (sliced raw skate) and the like. Each of the odor emission materials sprayed with the solution was shaken at a rotation speed of 60 rpm using a shaker machine (N-BIOTEK, ORBITAL SHAKER NB-101S) in order to uniformly disperse the solution, and the degree of odor emission was measured using an odor measuring device (COSMOS, XP-329 m).

Each of the odor emission materials sprayed with the solution was shaken at a rotation speed of 60 rpm using a shaker machine (N-BIOTEK, ORBITAL SHAKER NB-101S) in order to uniformly disperse the solution, and the degree of odor emission was measured using an odor measuring device (COSMOS, XP-329 m). The results thereof are shown in FIGS. 2C, 3C, 4C, 5C and 6C.
Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
The composition can capture and remove various kinds of odor materials (particularly, ammonium ion-containing bad odor, such as a fishy smell or the like) because cucurbituril can interact with various odor materials using its hydrophobic cavity and both inlets covered with carbonyl groups. Therefore, this composition can be practically applied to the cleaning of air and the improvement of an environment.
