Description

  The present invention relates to a deodorant having a deodorizing function and comprising a vetiver root extract as a main component.

  In recent years, the number of people who react sensitively to body odor, pet odor, cigarette odor, food odor, etc. has been increasing. If it is a body odor, it may be a smell unique to each person or an aging odor. As the trend toward emphasis on cleanliness and hygiene has increased, there has been an increasing desire to reduce the odors that are emitted from oneself. This desire is expected to increase with the aging of Japanese society.

  In addition, with the advancement of urban lifestyle and increased cleanliness, there is a growing desire to suppress or eliminate the smell of indoor pets and tobacco. Of course, when you want to remove the odor immediately, you often want to suppress the odor in daily life.

  Furthermore, as an extension of the desire to deodorize at home, there is a growing desire to deodorize outside of home. For example, the desire to deodorize the interiors of hotels and inns at travel destinations and business trips is increasing year by year. As a result, deodorants and fragrances are often installed in hotels and ryokan rooms. So-called spray-type deodorant bottles are installed in the rooms of hotels and inns.

  As described above, many deodorants installed in hotel rooms as well as homes are mainly composed of chemical components. A chemically synthesized deodorant containing a main component causes an unpleasant odor and a different odor to make it difficult to notice a bad odor or to decompose the cause of the bad odor. Chemically synthesized chemical components cause these functions, so that they are highly effective in that the odor is difficult to notice or the odor disappears.

  However, the deodorant mainly composed of these chemically synthesized chemical components may cause side effects because the main component is a chemical component. For example, chemical components may cause allergies or cause discomfort other than odor. With a deodorant mainly composed of chemical components, it is difficult to confirm all these side effects in advance.

  On the other hand, with increasing natural orientation, a deodorant having a natural component as a main component has been demanded rather than a deodorant having a chemical component as a main component. Even if the function of deodorizing is exerted, deodorants based on natural ingredients are more preferred by modern people than chemical ingredients. This is the same not only in Japan but also in other countries, especially in countries with high cultural maturity such as developed countries and emerging countries.

  In such a situation, a deodorant having a natural component as a main component is demanded. However, natural components exist in various ways and have problems such as difficulty in purification and difficulty in blending. In addition, natural components have a problem that it is difficult to determine whether the deodorizing function is versatile or only effective for a specific odor. In addition, even if the deodorizing effect can be confirmed by experiment, it is often difficult to analyze the deodorizing mechanism.

  Thus, although the deodorizer which has a natural component as a main component is calculated | required, it is the actual condition that the main technique has not been established. For this reason, deodorants installed in hotels, inns, etc. as well as homes are still mostly composed of such chemical components.

  Under such circumstances, vetiver, which is a perennial of the Gramineae, has attracted attention as having a high deodorant component. It has been known that components of vetiver roots have deodorant components and aroma components. For this reason, it has been proposed that a dried vetiver root or a dried vetiver root extract can be applied to a deodorant (see, for example, Patent Document 1).

JP 2010-94506 A

  Patent Document 1 discloses a deodorant containing an extract of a vetiver plant. It has been analyzed that the roots of vetiver, a perennial of the grass family, have a deodorizing component. Patent Document 1 proposes a deodorant focused on this deodorant component. Since the root of vetiver has a deodorizing component, it can achieve a function as a deodorant.

  However, even if the roots of vetiver have a deodorizing component, they cannot be used for universal deodorization. The roots of vetiver have a unique smell, but some people feel uncomfortable with this smell. When this deodorant is used for home use, there is no problem because it is used by people who match the taste, but when installed in public spaces such as hotels, inns, offices, etc. Is not preferred. There is a tendency to install deodorants that are easy to receive by the greatest common factor.

  The deodorant component of vetiver root is naturally a natural component, and there is no fear of causing side effects like a commercially available chemical component. In particular, it can be used safely without causing allergies in recent years. However, a further improvement in the deodorizing function and a fragrance whose preference is difficult to distinguish are necessary for the spread of a deodorant using a deodorizing component of the roots of vetiver.

  Although the prior art disclosed in Patent Document 1 has reached the focus on deodorant components in the roots of vetiver, it has been developed for technology development to spread as a deodorant (especially installed in public spaces). There was a problem that was not reached.

  An object of the present invention is to provide a deodorant using a vetiver root component which improves the deodorizing function and promotes leveling of taste.

  In view of the above problems, the deodorant of the present invention is a water-soluble extraction of 70% to 90% by volume of purified water and 5% to 10% by volume of vetiver roots with respect to the whole. Liquid and 0.5 volume% or more and 25 volume% or less ethanol formulation with respect to the whole.

  The deodorizing agent of the present invention can further enhance the deodorizing component by including other compounding components while containing the extract of vetiver root as a main component. Of course, since it is a natural ingredient, it does not cause side effects such as human body allergies.

  In addition, the deodorant of the present invention not only exhibits a deodorizing function but also does not make a strong awareness of palatability during actual use by including the compounding components at an optimal ratio. As a result, it can be easily installed in guest rooms, offices, public transportation and public spaces of hotels and inns.

  Combined with these, deodorants mainly composed of natural ingredients that are gentle on human bodies and pets become more widespread.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  (Embodiment)

(Overview)
Vetiver (scientific name “Vetiveria Zizaniodes”) is a grass perennial native to India, and its dried root is used in the powder of the first embodiment. Vetiver has leaves that resemble Susuki, which reach a length of 2-3 m. In addition, the roots grow deep underground 1-2 m and have a strong scent. The roots are steam distilled and dried to be used in the embodiment. The roots of the vetiver come to exhibit their inherent effects when dried. This effect includes a deodorizing function.

  The roots of vetiver contain various components, but mainly contain vetiverol and the like.

  As the deodorant in the embodiment, a water-soluble extract of this vetiver root is used. By using a water-soluble extract of vetiver root, the deodorant obtained is also liquid, and there is an advantage that the deodorant is used in a container for spraying or spraying.

  The deodorant in the embodiment is 70% by volume or more and 90% by volume or less of purified water with respect to the whole deodorant, and 5% by volume or more and 10% by volume or less of water of vetiver root with respect to the whole deodorant. Sex extract (hereinafter referred to as “vetiver extract”) and an ethanol preparation in an amount of 0.5% by volume to 25% by volume based on the whole deodorant. Here, the deodorant defined by this component ratio is defined as the deodorant 1.

  The deodorant 1 can exhibit high deodorizing ability by having these component ratios. The deodorant 1 contains the purified water and the ethanol preparation in the above-mentioned component ratios as the main component, while the vetiver extract capable of exhibiting the deodorizing function is included as a main component, the efficacy of the vetiver extract is further exhibited. In particular, when the deodorant 1 contained in the container is ejected, the vetiver extract is diffused together with the vaporization of the ethanol preparation. As a result, the deodorizing function of the vetiver extract is highly exhibited.

  Moreover, since the deodorizer 1 is a liquid, it is packed in a container that can be sprayed out in a spray or mist state, and can be used in various places. The user holds the container and then blows out the deodorant as the contents to deodorize the room or deodorize the clothes. When the clothes are deodorized, the sprayed deodorant may be sprayed on the clothes.

  Since the deodorant 1 is a liquid, it is easy to store in the container. The deodorant 1 contained in the container in this way can easily be prepared in an office or a hotel as a matter of course at home. For example, deodorants are often placed in hotels and inns for customers who are concerned about smell. As part of these deodorants or as a replacement for these deodorants, they are installed in the rooms of hotels and inns. By being installed in these places, customers who care about odors do not feel uncomfortable.

  The vetiver extract may be extracted from the dried vetiver roots by various methods. For example, dried vetiver roots are soaked in water. Furthermore, autoclave extraction is performed at 100 ° C. to 125 ° C. for 30 minutes to 40 minutes. By autoclave extraction, a water-soluble extract can be easily obtained from dried vetiver roots. In particular, since the working time is short, it is easy to obtain a water-soluble extract.

  Alternatively, the dried vetiver root may be immersed in water and extracted with hot water at 50 to 65 ° C. for 1 to 2 hours. The hot water extraction ensures that a water-soluble extract is obtained from the dried vetiver roots. Although hot water extraction takes time, it is extracted slowly, so that the extracted water-soluble extract has the advantage that the degree of purification is very high.

  Moreover, what is necessary is just to extract by the method generally known besides autoclave extraction or hot water extraction.

  In addition, an extract containing a water-soluble extract of vetiver root can be used as a deodorant as it is, but the extract is concentrated by a concentration method such as centrifugal concentration, heat concentration, vacuum concentration, autoclave concentration or the like. It can also be used as a deodorant. The process when the concentrated vetiver extract is mixed with the deodorant (deodorant 1 or other deodorant described later) is facilitated.

  Alternatively, the concentrated vetiver extract may be diluted and then mixed with purified water or an ethanol preparation to produce a deodorant.

  Moreover, the vetiver extract is brown because it is extracted from vetiver plants. However, if the vetiver extract is colored, the clothing will be discolored when the deodorant is sprayed on the clothing, so it is also preferable to remove the brown component. For example, the brown component is removed by filtering the vetiver extract with a filter paper, filtering with a cellulose membrane having a membrane pore size of 0.2 μm, or adsorbing the brown component with a synthetic adsorbent.

  Of course, since the brown component has only a low pigmentation power, the brown component may be used as a deodorant without being removed (or simply removed). If the brown component remains, the deodorant will be colored, and it will be clear that it is a deodorant mainly composed of vetiver extract, which may be preferable depending on the user. .

  The deodorizer 1 is obtained by mixing purified water and an ethanol preparation with the vetiver extract thus obtained in the above-described ratio. In addition, mixing an inevitable mixture is not excluded.

  For example, when the deodorant 1 is ejected indoors, it can reduce or eliminate the smell of cigarettes in the room, the smell of pets, the smell of garbage, the smell of sweat, and the like. Further, when the deodorant 1 is sprayed on clothes, it can reduce or eliminate the smell of cigarettes on the clothes, the smell of pets, the smell of garbage, the smell of sweat, and the like. In particular, it is possible to reduce or eliminate the trimethylamine odor, which is a raw odor such as garbage, and the ammonia odor, which is a sweat odor. This is because the vetiver extract contained in the deodorant 1 is considered to decompose the trimethylamine odor and the ammonia odor.

  Further, as described above, by mixing with purified water, the vetiver extract can be diffused by the ethanol preparation while being easily stored and carried. Combined with these, the deodorant 1 can exhibit a high deodorizing effect.

(Deodorant 2)
Moreover, it is also suitable that the deodorizer using a vetiver extract is obtained by other component ratios.

  Deodorant 2 comprises 70% by volume or more and 80% by volume or less of purified water with respect to the entire deodorant, 5% by volume or more and 6% by volume or less of a vetiver extract, and the deodorant. And 20% by volume or more and 25% by volume or less of an ethanol preparation. Of course, the inclusion of inevitable mixtures is not excluded.

  Unlike the deodorant 1, the deodorant 2 has a more limited volume ratio of the vetiver extract. By this limitation, together with other component ratios, the deodorant 2 can produce a more reliable and constant effect. Naturally, the manufacturing cost can be reduced because the amount of vetiver extract is limited.

  The vetiver extract used for the deodorant 2 may be obtained by the same means as described for the deodorant 1. The deodorant 2 is obtained by adding a vetiver extract and an ethanol preparation to purified water and stirring.

  The deodorant 2 also exhibits the function of reducing or eliminating the trimethylamine odor of the vetiver extract and the ammonia odor which is the sweat odor by diffusing with the ethanol preparation.

  Since the deodorant 2 is also a liquid, it can be packed in a container and can be ejected in the form of a spray or mist. For this reason, it can be installed in various places, and its utilization spreads. Of course, the deodorant 2 only contains purified water, vetiver extract, and ethanol preparation (except for the unavoidable mixture), all of which are natural ingredients. Contains no chemically synthesized chemical components. As a result, it is gentle to the human body and less likely to cause allergies or discomfort.

  In addition, the deodorant 2 (which is the same for the deodorant 1 and the like) containing a natural component as a main component is less likely to be soiled or spoiled even when sprayed on clothes or walls. For this reason, it can be easily used for many purposes. As a result, the deodorant of the present invention is easily spread widely.

(Deodorant 3)
The deodorant 3 is configured with a predetermined component ratio.

  Deodorant 3 comprises 73% by volume purified water based on the entire deodorant, 5% by volume vetiver extract with respect to the entire deodorant, and 22% by volume ethanol formulation with respect to the entire deodorant. ,including.

  The deodorant 3 is thus produced at a constant component ratio. By specifying the component ratios in this way, it is possible to obtain the deodorant 3 that is easy to manufacture and can exhibit a certain effect.

  Since the deodorant 3 also contains the ethanol preparation while containing the vetiver extract, the vetiver extract is easily diffused by the diffusion of the ethanol preparation. Since the content of the vetiver extract is 5% by volume with respect to the deodorant 3, the deodorant 3 has a sufficient amount of the vetiver extract. This vetiver extract has a function of reducing or eliminating trimethylamine odor and ammonia odor, which is a sweat odor, and the deodorant 3 uses this function to reduce or eliminate an unpleasant odor. .

  Further, the vetiver extract is not too strong depending on the mixing ratio of the vetiver extract specified by each of the deodorants 1, 2, and 3. The vetiver extract has a unique odor derived from the roots of the vetiver, but the mixing ratio of the vetiver extract is such that it is specified by the deodorizers 1 to 3, which makes it uncomfortable during use. Absent. In addition, if the deodorizing function is too strong, the necessary odor may be lost or physical wear may be caused. Such problems are less likely to occur.

  In addition, each of the deodorizers 1 to 3 contains an ethanol preparation, and the mixing ratio of the ethanol preparation is also as described above. As a result, there are neither too much nor too few ethanol formulations. If the amount of ethanol preparation is too small, the vetiver extract is difficult to diffuse or volatilize when ejected from the container. When there are too many ethanol formulations, the problem that the vetiver extract at the time of ejecting from a container will be too diffused or volatilized may arise. Naturally, there is also a problem that the deodorant is too volatile during storage in the container.

  These problems are unlikely to occur when the mixing ratio of the ethanol preparation follows the definitions of the deodorants 1 to 3.

  Moreover, the mixing ratio of purified water is also defined by the deodorizers 1 to 3, so that the deodorizing function is not weakened or the storage becomes difficult. As described above, the deodorizers 1 to 3 can achieve both a high deodorizing effect and ease of use.

(Deodorant containing essential oil)
The deodorant described in the deodorizers 1 to 3 may further contain an essential oil. Essential oil is an oil component extracted from various natural materials, and has an aromatic component in addition to various effects.

  A deodorant using a vetiver extract has an odor unique to vetiver. The odor unique to vetiver is where the taste is divided, but it may be noticed by some users. Moreover, it is inadequate as a product lineup that a deodorant has only one fragrance.

  Essential oils have various fragrance components and are added to deodorants to suppress odors unique to vetiver and to generate other odors. As a result, the deodorant can increase the product lineup while increasing the user's comfort.

  The essential oil may be mixed in an amount of 0.03% by volume or more and 0.1% by volume or less with respect to the entire deodorant. If it is this mixing ratio, the fragrance by essential oil will not become strong too much. Oil production at this mixing ratio may be mixed with the deodorant described in any one of the deodorizers 1 to 3.

  The essential oil may be selected in relation to the product lineup for convenience in production. For example, ylang ylang essential oil is preferably used. This is because when this is used, a very good fragrance spreads.

  Of course, essential oils other than ylang ylang may be used. Various essential oils may be selected according to the convenience of the manufacturer or user. The mixing ratio may also deviate from the above 0.03% by volume to 0.1% by volume.

(Deodorant 4)
The deodorant 4 is a deodorant when the essential oil is included, and the mixing ratio of each component is specified.

  The deodorant 4 comprises 89% by volume of purified water with respect to the whole deodorant, 10% by volume of vetiver extract with respect to the whole deodorant, and 0.9% by volume with respect to the whole deodorant. An ethanol formulation and 0.1 volume% of essential oil with respect to the whole deodorizer are included. Of course, inevitable mixtures may be included. Since the deodorizer 4 contains 10% by volume of vetiver extract, it can exhibit a sufficient deodorizing function. In addition, since there is not too much vetiver extract, the odor unique to vetiver is not too strong.

  Moreover, the fragrance derived from essential oil arises by containing 0.1 volume% essential oil. This aroma further enhances the user's comfort. Of course, not only deodorizing, but also aroma is generated, which makes it more comfortable to use.

  Since the deodorant 4 is also a liquid, it can be stored in a container and installed in various places. As a result, the use opportunity increases and the spread of the deodorant 4 proceeds.

  As described above, it is also preferable that the essential oil is further contained.

    (Experimental result)

  The confirmation experiment of the deodorizing function by the vetiver extract will be described.

(Ammonia deodorization experiment 1)
100 g of dried vetiver root (an example of a vetiver plant) is soaked in 1.8 liters of water and subjected to autoclave extraction at 121 ° C. for 40 minutes, followed by centrifugal concentration and filtration to obtain an autoclave extract. It was. The extraction rate of water-soluble components in autoclave extraction (weight of water-soluble components per 100 g of vetiver root) was 6.31%. In addition, as a result of performing autoclave extraction similarly except the point which is not filtering, the extraction rate of the water-soluble component was 7.66%.

  Moreover, 100 g of dried vetiver roots were immersed in 1.8 liters of water, and hot water extraction was performed at 55-60 ° C. for 1.5 hours, followed by centrifugal concentration and filtration to obtain a hot water extract. . The extraction rate of the water-soluble component in the hot water extraction was 6.42%.

  Next, the cap at the mouth of the 5 liter Tedlar bag was removed and replaced with a silicon tube having a thickness suitable for the detection tube, and the corner of the Tedlar bag was bent as a reagent injection place and stopped with tape. A cut end was put on the unfolded end so that the volume did not change, and a hot water extract precisely weighed to about 5 ml was put through the cut end, and then the cut end was sealed with tape.

  Then, the air inside the Tedlar bag was evacuated with a pump, 4 liters of compressed air was introduced using an integrating flow meter, and the silicone tube was closed with a clip and sealed. A microsyringe (10 microliter volume) was stabbed into a portion that was bent and stopped with tape, that is, a portion to which the hot water extract was not attached, and 3 microliters of 25% ammonia water was injected.

  Then, the portion where the hole was opened by the microsyringe was immediately closed with tape, and the entire Tedlar bag was heated with a dryer to vaporize the solution (initial ammonia concentration: 600 ppm). Then, after 2 minutes, 10 minutes, 20 minutes, 40 minutes and 80 minutes, the ammonia concentration is measured by using a detector and a detector tube at intervals, and the residual ammonia rate is calculated. did.

  Moreover, after putting the autoclave extract accurately weighed to about 5 ml from the cut end, it was sealed with a tape and the same test as above was performed.

  For comparison, simple water precisely weighed to about 5 ml was added from the cut end, and the cut end was sealed with tape, and the same test as described above was performed. The results are shown in FIG. FIG. 1 is an explanatory diagram showing the results of an ammonia deodorization experiment 1 in the embodiment of the present invention.

  As can be seen from FIG. 1, the autoclave extract and the hot water extract extracted from the dried vetiver roots are both 50% or more when the deodorization of ammonia has started for 2 minutes (ie, ammonia remaining). The rate was 50% or less).

(Ammonia deodorization experiment 2)
100 g of dried vetiver root is immersed in 1.8 liters of water, and hot water extraction is performed at 55-60 ° C. for 1.5 hours, followed by centrifugal concentration and filtration, and further at 100 ° C. for 1.5 hours. Concentration by heating gave a vetiver root hot water extract. The extraction rate of the water-soluble component was 5.39%.

  In addition, in order to compare with vetiver root hot water extract, corn-derived component extract deodorant [Fabries (registered trademark), manufactured by P & G Co.] (water-soluble component content: 1.94 g / 100 ml) and catechin-derived A component extract liquid deodorant [Risesh (registered trademark), manufactured by Kao Corporation] (water-soluble component content: 1.11 g / 100 ml) was prepared.

  Next, the cap at the mouth of the 5 liter Tedlar bag was removed and replaced with a silicon tube having a thickness suitable for the detection tube, and the corner of the Tedlar bag was bent as a reagent injection place and stopped with tape. A cut end was put in the unfolded end so that the volume did not change, and a vetiver root hot water extract precisely weighed to about 3 ml was put through the cut end, and then the cut end was sealed with tape.

  Then, the air inside the Tedlar bag was evacuated with a pump, 4 liters of compressed air was introduced using an integrating flow meter, and the silicone tube was closed with a clip and sealed. A microsyringe (10 microliter volume) was stabbed into a portion that was bent and stopped with tape, that is, a portion where the vetiver root hot water extract was not attached, and 3 microliters of 25% ammonia water was injected.

  Then, the portion where the hole was opened by the microsyringe was immediately closed with tape, and the entire Tedlar bag was heated with a dryer to vaporize the solution (initial ammonia concentration: 400 ppm). Then, after 2 minutes, 10 minutes, 20 minutes, and 40 minutes, the ammonia concentration was measured using a detector and a detector tube, and the residual ammonia rate was calculated.

  Moreover, after putting the corn-derived component extract deodorizer precisely weighed to about 3 ml from the cut, it was sealed with a tape and the same test as above was performed.

  Further, a catechin-derived component extract deodorant precisely weighed to about 3 ml was added from the cut end, and the cut end was sealed with tape, and the same test as described above was performed.

  In addition, a simple water precisely weighed to about 3 ml was added from the cut end, and then the cut end was sealed with tape, and the same test as described above was performed. The results are shown in FIG. FIG. 2 is an explanatory diagram showing the results of the deodorization experiment 2 in the embodiment of the present invention.

  As can be seen from FIG. 2, the vetiver root hot water extract was 80% deodorized (ie, 20% ammonia residual rate) after 10 minutes from the start of ammonia deodorization, whereas corn-derived components The extract liquid deodorant only deodorized 65% (that is, the ammonia residual ratio was 35%) when 10 minutes had passed since the deodorization of ammonia was started. In addition, the catechin-derived component extract deodorizer only deodorized 40% (that is, the ammonia remaining rate was 60%) when 10 minutes had passed since deodorization of ammonia was started.

  Furthermore, the vetiver root hot water extract decreased the residual ammonia rate after 20 minutes or 40 minutes after the start of deodorization of ammonia, whereas the corn-derived component extract deodorant was ammonia. After 10 minutes from the start of deodorization, there was almost no change in the residual ammonia rate, and in the case of catechin-derived component extract liquid deodorizer, the residual ammonia rate was almost 2 minutes after the start of deodorization of ammonia. There was no change.

A cut was made at the unfolded end so that the volume did not change, and the first vetiver root hot water extract precisely weighed to about 3 ml was put through the cut and then sealed with tape.

  Then, the air inside the Tedlar bag was evacuated with a pump, 4 liters of compressed air was introduced using an integrating flow meter, and the silicone tube was closed with a clip and sealed. A microsyringe (10 microliter volume) was pierced into the portion that was bent and stopped with tape, that is, the portion where the first vetiver root hot water extract was not adhered, and 3 microliters of 25% ammonia water was injected.

  Then, the portion where the hole was opened by the microsyringe was immediately closed with tape, and the entire Tedlar bag was heated with a dryer to vaporize the solution (initial ammonia concentration: 400 ppm). Then, after 2 minutes, 10 minutes, 20 minutes, and 40 minutes, the ammonia concentration was measured using a detector and a detector tube, and the residual ammonia rate was calculated.

  Moreover, after putting the 2nd vetiver root hot water extract precisely weighed to about 3 ml from a cut end, it sealed the cut end with the tape, and performed the same test as the above.

  Further, a third vetiver root hot water extract precisely weighed to about 3 ml was put through the cut end, and then the cut end was sealed with tape, and the same test as described above was performed.

  In addition, a simple water precisely weighed to about 3 ml was added from the cut end, and then the cut end was sealed with tape, and the same test as described above was performed. The results are shown in FIG. FIG. 3 is an explanatory diagram showing the results of the deodorization experiment 3 in the embodiment of the present invention.

  As can be seen from the comparison between FIG. 2 and FIG. 3, the vetiver root hot water extract has an ammonia deodorizing effect than the catechin-derived component extract deodorant even when the brown component is removed by the cellulose membrane or the synthetic adsorbent. it was high.

  As described above, the vetiver extract has a high ammonia deodorizing effect. Since this vetiver extract is added at an optimal mixing ratio, each of the deodorizers 1 to 4 can realize a high storability and a high feeling of use while exhibiting a high deodorizing effect.

  The deodorant described in the embodiment is an example for explaining the gist of the present invention, and includes modifications and alterations without departing from the gist of the present invention.
