DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorant,
Just leave it near the odorous object or in the space where the odor is contained,
The present invention relates to a deodorant having an effect of promptly eliminating smell.

[0002] The deodorant according to the present invention has an effect of quickly eliminating dead odor and perishable odor generated from a body that had no deodorant effect with the conventional deodorant, so that its discovery is delayed and the odor of the perishable odor is remarkable. By spraying around the body, treatment of the corpse can be facilitated.

Further, the deodorant according to the present invention has an effect of suppressing the progress of decay of a corpse simply by being left near the corpse, so that the casket is cooled with dry ice until cremation. Can be eliminated.

Further, the deodorant according to the present invention is effective against various odors other than the dead odor, for example, the odor of putrefaction generated from garbage and fish ash, the odor of tobacco generated by smoking, the odor of toilet and human waste, and the like. It also has a deodorizing effect, and if you leave or spray it in places dealing with rotten garbage, smoking rooms and trains, toilets and human waste disposal places, you will not feel these odors, so you will get a comfortable environment Can be.

Further, since the deodorant according to the present invention can be easily added to a resin such as polyethylene and molded, a resin molded product having a deodorizing effect, for example, a garbage which does not give a smell of garbage. Can be used as bags or buckets.

[0006]

2. Description of the Related Art Various substances known to have a deodorizing effect by a mechanism such as adsorption, absorption, decomposition, and masking have been known, and various deodorants using these substances have been developed. It has been. For example, coconut charcoal, activated carbon fiber, silica gel, zeolite, chlorine compounds such as calcium chloride, zinc white, various metal soaps, ethylene glycol and analogs, boron compounds such as borax, phenols, various peroxides, Ester surfactants, mixtures of ferrous sulfate and ascorbic acid, stabilized chlorine dioxide, various essential oils and plant extracts are known.

[0007] In the deodorant by the mechanism of adsorption, absorption and decomposition, if a method of forcibly circulating the air containing the odor through the deodorant can be used, effects such as adsorption, absorption and decomposition are produced. Odor components can be effectively removed. However, in the absence of forced circulation equipment, it is inevitable to use these deodorants in an odorous room. No deodorizing effect can be expected.

[0008] Liquid deodorants that are sprayed to the source of the odor have also been known, but have the drawbacks that they are cumbersome to use, have limited targets, and have insufficient sustainability. .

When the type of odor is limited to the dead odor from the dead body, if a person dies, a dry odor is placed in the coffin in order to suppress the progress of the decay of the dead body and the generation of the dead odor until cremated. It is common to put ice to cool the body, but it is not possible to completely suppress the dead smell, and it also has the disadvantage that the body becomes cold and loses its natural appearance and costs increase was there.

[0010] Furthermore, dry ice cannot be used to eliminate the rotten odor generated from a body that has been discovered and delayed and has undergone decay. As a method other than dry ice,
A deodorant in which activated carbon fiber is mixed into a nonwoven fabric is known, but has the disadvantage of being expensive, and has no effect of quickly eliminating the decaying odor from a decayed body that has been discovered late and has been decayed. . As other deodorants for mortuaries, those that generate chlorine dioxide are known, but they are not widely used because they have a problem of giving a pungent odor to users.

[0011] When the deceased body is found and taken by the police, there is no other effective method. Therefore, an attempt is made to burn the incense and mask the decay odor with the smell of the incense, but it does not have a sufficient deodorizing effect. .

[0012]

SUMMARY OF THE INVENTION The present invention relates to various odors encountered in daily life, such as dead odors and rotten odors from dead bodies, putrefaction odors of garbage, odors of toilet waste, and odors of cigarette smoke. It is conceived to provide a comfortable environment by eliminating odors of hospital disinfectants and filth by a simple and safe method.

DESCRIPTION OF THE PREFERRED EMBODIMENTS It is already known that various essential oils or compounds contained in essential oils have a deodorizing effect. The mechanism is said to be a masking effect or an absorption effect, but has not been completely elucidated. These plant-derived components generally have low toxicity and thus have an easy-to-use aspect, and many inventions have been proposed. However, in fact, the deodorizing effect itself is not very strong, it is used only for deodorizing flush toilets and removing bad breath, and it fills the room with a refreshing scent rather than deodorizing Such applications are aimed at so-called Finton Chid or aromatherapy.

As described above, the deodorizing effect of essential oils has been conventionally known, but a strong deodorizing effect of eliminating intense malodor such as rotten odor from the remains is not known.

The inventor of the present invention has studied again the deodorizing effect of the essential oil-based compound, and found that camphor and methyl salicylate are
It has been found that the present invention has a considerable effect of eliminating an intense smell such as animal odor, and has made various efforts to arrive at the present invention.

That is, it has been found that, by mixing camphor and methyl salicylate alone, by mixing them, not only the effect of reducing the rotten odor of the animal but also the effect of deodorizing it can be obtained. That is, when camphor and methyl salicylate are used alone, the rotten odor is considerably reduced, but a slightly irritating odor peculiar to camphor and methyl salicylate is felt.

However, when these are mixed and used,
The irritating odor of camphor and methyl salicylate remaining after use is also considerably reduced, and an effect closer to deodorization is obtained rather than masking of malodor. In addition, it has a wide range of deodorizing effects on various bad odors in daily life, such as the smell of cigarette smoke, the odor of toilets and human waste, as well as the deodorizing odor of animals. Is also obtained.

Further, it has been found that the practicality is further improved by adding another essential oil having an aroma as the third component to the mixture of camphor and methyl salicylate. In other words, the odor of camphor and methyl salicylate itself is slightly irritating and may be disliked by some people, but by adding essential oil, the smell of the deodorant itself before use becomes mild and stimulating. Disappears. In addition, when applied to an odor source, the effect of eliminating the odor remains unchanged, but the odor remaining after use is further weakened, and the odor eliminating effect is obtained in practice. Essential oils that can be used here include peppermint oil, sweet orange oil, mandarin oil, lemon oil, lavender oil, rose oil, turpentine oil, hinoki oil and the like.

In place of these essential oils, the main components contained in the essential oils, for example, pure products such as menthol and limonene can be used, but the essential oils are generally more advantageous in terms of price. Conversely, also for camphor and methyl salicylate, which are the main components of the present invention, essential oils containing them as main components, that is, camphor oil and wintergreen oil, can be used instead of pure products.

A mixture of two components, camphor or methyl salicylate, and essential oil is sufficient for deodorizing household garbage and flush toilets. However, strong odors such as rotten odors from dead bodies are sufficient. Preferably, a mixture of camphor, methyl salicylate and essential oil is used.

As for the composition of the mixture, since the deodorizing effect does not change sharply depending on the mixing ratio, a mixture having a wide range of compositions can be used. In the case of the two-component system of camphor and methyl salicylate, the mass ratio of camphor / methyl salicylate is 10/90 to 90/10, preferably 15/85.
８５85/15. In the case of a three-component system to which essential oil is added, the mass ratio of the sum of camphor and methyl salicylate to the essential oil is 90/10 to 20/80, preferably 85/20.
It is in the range of 15-60 / 40. In the case of a two-component mixture of camphor and methyl salicylate and essential oil, the mass ratio of camphor or methyl salicylate to essential oil is still 90%
/ 10-20 / 80, desirably 85 / 15-60 /
It is in the range of 40.

The deodorant mixture according to the present invention can be used as a liquid deodorant such that it is diluted with an odorless solvent such as alcohol or ethylene glycol and sprayed. It can also be used as an apparently solid deodorant by carrying it on a solid such as high-quality inorganic powder or cloth.

Surprisingly, such solid deodorants can only be sprayed in small amounts in rooms with bad odors,
That is, the odor can be quickly eliminated without forcibly circulating the indoor air through the deodorant.

[0027] The carrier used herein is a carrier which hardly emits an odor itself, and which does not dissolve in the deodorant mixture according to the present invention, and which can support a certain amount of the deodorant mixture. If there is, it is not particularly limited. For example, there are inorganic powders, and porous materials such as diatomaceous earth, perlite, pulverized bricks, and pulverized ALC are preferable because they carry a large amount of powder. The particle size of the powder is not particularly limited, but it is easier to handle when a powder of about 1 to 3 mm is sprayed than a fine powder.

Examples of the organic carrier include cloth and paper, or a crushed product thereof, nonwoven fabric, cotton, and polyurethane sponge having open cells. Even if the synthetic resin is not porous, the synthetic resin that can dissolve and hold the deodorant mixture therein can be used as a carrier. For example, low-density polyethylene, ethylene / vinyl acetate copolymer, styrene / butadiene copolymer, etc. are suitable, and powder or pellet forms are easy to use.

The deodorizing mixture according to the present invention can be easily added to a resin such as polyethylene and molded, so that, for example, a garbage bag or a trash bucket having a deodorizing effect can be obtained.

[0030]

Examples 1 to 20 and Comparative Examples 1 to 25 25 polyethylene wide-mouthed bottles each having a capacity of 500 ml were prepared, and about 80 g of live clams were put into each of them, covered, and allowed to stand at room temperature for 2 weeks. Two weeks later, when the lid was removed, a noticeable smell of putrefaction was felt.

Each of the compounds having a deodorizing effect or a mixture of compounds (hereinafter, referred to as deodorizing components) shown in Table 1 was dissolved in ethanol to prepare an ethanol solution. 1
Twenty-five sets of 10 pieces of 0 cm square gauze were prepared, and 5 ml of different types of ethanol solutions were dropped into each of them using a pipette, and the ethanol was evaporated by sending cold air for 10 minutes. The concentration of the ethanol solution was adjusted so that the mass of the deodorant component contained in each gauze was 300 mg. The gauze containing the deodorant component thus prepared was placed in a wide-mouthed bottle containing putrid clam shells, covered, and left for 20 minutes. Then I took off the lid and smelled it. Table 1 shows the results.

Comparative Examples 2 and 3 are components which are said to have a deodorizing effect, but could not eliminate intense putrefaction odor as in this example. Comparative Examples 4 and 5 are also components that are said to have a deodorizing effect, but probably because they have a stronger irritating odor than the components of Comparative Examples 2 and 3; The effect of eliminating putrefaction odor was greater than that of, but it was not completely eliminated. Further, the smell of the deodorant component itself was considerably felt.

In contrast, Embodiments 1 and 2 according to the present invention
At 0, a large deodorizing effect was obtained as compared with the comparative example. Examples 1-4 Combining Methyl Salicylate and Camphor
Then, the intense putrefaction odor was almost completely lost, but the odor of the deodorant component itself was slightly felt. In Examples 12 to 20 to which essential oils were further added, not only the odor of putrefaction but also the odor of the deodorant component itself was very weak, and the odor was substantially odorless.

In Examples 4 to 11 in which essential oil was combined with either methyl salicylate or camphor, the putrefaction odor remained slightly, but the odor of the deodorant component itself was also very weak.

The deodorant according to the present invention is capable of masking a strong odor such as putrefaction odor with another odor,
Has the effect of substantially eliminating odor.

[0036]

Example 21 A mixture of methyl salicylate, camphor oil and peppermint oil was prepared at a mass ratio of 1/1/1, and the mixture was sprinkled on a refractory brick (Uniport C manufactured by GL Sciences, particle size: 30 to 60 mesh). To obtain a solid deodorant. The mass ratio of the refractory brick pulverized material to the mixture was 7/3. This 1 g was wrapped in a non-woven fabric,
As in the case of No.-20, put in a wide-mouthed bottle containing putrid clam shells to test the deodorizing effect. As a result, as shown in Table 1, an almost deodorizing effect was observed.

[0037]

Example 22 A mixed solution of methyl salicylate, camphor oil and limonene in a mass ratio of 1/1/1 was prepared, and the deodorizing effect was tested in the same manner as in Example 21. As a result, as shown in Table 1, an almost deodorizing effect was observed.

[0038]

Example 23 An old man living alone was found dead at home. An estimated one week had passed since he died, and the odor was noticeable and it was difficult to enter the room. When the funeral home, which accommodated the corpse, sprayed 60 grams of the deodorant of Example 21 around the corpse, almost no odor was sensed in about 15 minutes, and there was no hindrance to accommodating the corpse. Was.

[0039]

EXAMPLE 24 Another old man living alone was found dead at home. It was estimated that nearly one week had passed since he died, and that it was difficult to enter the room due to a noticeable odor. When the funeral home, which contained the body, sprayed 60 grams of the deodorant of Example 22 around the body, about 15
In about a minute, the smell was almost inaudible, and there was no hindrance to housing the body.

[0040]

[Example 25] An alien living alone died of sickness. It took time to get consent from the relatives for cremation, and they were kept in a crematorium refrigerator (about 3 degrees Celsius) for five days. Normally, dry ice is put in the refrigerator, but dry ice is not put in.
0 grams were divided into seven non-woven bags and placed around the body in the refrigerator. Five days later, the body was removed for cremation, but no signs of decay and no progress of decay were observed.

[0041]

Example 26 A sick person died. Seven nonwoven bags containing the same deodorant as in Example 25 were placed on the bottom of the coffin. Even without the dry ice, not only the dead odor and the rotten odor were not felt for 54 hours before the cremation, but also the peculiar odor associated with the cremation, which was usually felt during the cremation.

[0042]

Example 27 A mixed solution of methyl salicylate / camphor oil / mint oil having a mass ratio of 1/2/1 was prepared, and 100 g of the mixed solution was mixed with an ethylene / vinyl acetate copolymer (manufactured by Mitsubishi Chemical Corporation, vinyl acetate content: 20% by mass). %) Of pellets were added and left for 4 hours with occasional stirring to absorb all of the mixture into the pellets. The pellets were mixed with pellets of low-density polyethylene (manufactured by Mitsubishi Chemical Corporation) at a ratio of 3/100 to form a blown film having a thickness of 60 microns.
When the concentration of the deodorant in the formed film was analyzed by headspace gas chromatography, the concentrations of methyl salicylate, camphor, and menthol were 3200, 5900, and 3000, respectively.
ppm.

The blown film was cut open flat, processed into a delivery bag, and laid under the body in the coffin. Even without dry ice, neither dead nor rotten smell was felt for 48 hours before cremation.

[0044]

Example 28 Mass Ratio of Methyl Salicylate / Mentha Oil 1
/ 2 mixture was prepared, 100 g of ethylene / vinyl acetate copolymer pellets (manufactured by Mitsubishi Chemical Corporation, vinyl acetate content: 20% by mass) was added to 100 g of the mixture, and the mixture was allowed to stand for 4 hours with occasional stirring. Absorbed in pellets. This is made of high-low density polyethylene (Mitsubishi Chemical pellets and 2
The mixture was mixed at a ratio of / 100 to form a blown film having a thickness of 40 microns. When the concentration of the deodorant in the formed film was analyzed by a head space gas chromatography, the concentrations of methyl salicylate and menthol were 3100 and 5600 ppm, respectively. As a blank, a film to which no deodorant was added was also formed.

Each film was processed into a bag, and the garbage discharged from the kitchen at home was divided into two, put into each, and the upper end of the bag was tied and allowed to stand. Five days later, when each was opened, a putrid odor was found from the blank bag, but no putrid odor was felt from the bag to which the deodorant of the present invention was added.
Further, even when the garbage was taken out of the bag to which the deodorant of the present invention was added and the odor was smelled, no odor of putrefaction was perceived, so that it was found that the progress of putrefaction was suppressed.

[0046]

Example 29 5 g of ethylene / vinyl acetate copolymer pellets having absorbed the mixed solution of Example 28 were placed in a dust bag of a household vacuum cleaner to clean the room. When the pellets were not inserted, a moldy smell was felt in the exhaust gas, but when the pellets were inserted, the mold smell disappeared.

[0047]

Example 30 5 g of the same pellets as in Example 27 were wrapped in a nonwoven fabric, pumped, and placed in a removable toilet. The smell of human waste in the toilet can no longer be felt.

[0048]

Example 31 When entering a smoking room of a building, the smell of cigarette smoke was strongly felt. 5 g of the ethylene / vinyl acetate copolymer pellets having absorbed the mixture of Example 27 were wrapped in a nonwoven fabric and placed in a room, and the room was left without ventilating.
After re-entering after 15 minutes, the smell of cigarette smoke was not felt and the smell of the deodorant was hardly felt.
