Description

Air purifier using ozone water generator {Dust Collector using Ozon Water}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifier using an ozone water generator, comprising: a odor purifier for purifying air containing pollutants containing odorous components, wherein the gas is supplied by supplying high concentrations of oxygen to generate ozone; After mixing with water to generate liquid ozonated water, gaseous ozone which has not been dissolved is separated through a gas-liquid separator, so that ozone water is used to purify the air through the metal filter unit and gaseous ozone flows through the metal filter. An air purifier using an ozone water generator, characterized in that it is used to purify ozone water containing pollutants.

In general, air containing contaminants containing malodorous components is generated in indoor spaces such as food cooking facilities, nursing homes and hospitals. In the indoor space in which air containing pollutants containing such odorous components are generated, it is necessary to discharge or purify the air. In the past, only an exhaust device that discharges pollutant-containing air to outside air is used. come.

However, such a simple exhaust device, since the air containing the harmful pollutant is discharged to the outside as it is, there is a problem that seriously affect the environmental pollution. In addition, there is a problem that a simple exhaust in the indoor space where the cooling or heating is made to reduce the cooling / heating efficiency.

In order to solve the problem of the existing simple exhaust device, various embodiments of a purification device for purifying air containing contaminants have been proposed and implemented, and as one embodiment thereof, ozone is removed as shown in FIG. There was a odor purifier used.

The conventional odor purifying device using ozone is oxidized by combining with active oxygen such as pollutants or airborne bacteria that cause odor by using the strong oxidizing power of active oxygen (O) generated by ozone decomposition. The principle of bactericidal action is to use.

The odor purifier using the conventional ozone as described above is decomposed to oxygen in the air through the same process as expressed in the formula (1) below by using a spark caused by electric discharge in the air as shown in FIG. / Combined to generate gaseous ozone.

Figure 112013021449299-pat00001

Figure 112013021449299-pat00002

However, in the process of generating gaseous ozone using such electric discharge, there is a problem that gaseous ozone has a peculiar odor, as well as a chemical reaction occurs to nitrogen (N) contained in the air by electric discharge. As represented by the formula (2) there was a problem that a NOx compound for generating various odors occur.

Figure 112013021449299-pat00003

Figure 112013021449299-pat00004

On the other hand, in order to facilitate the deodorization / sterilization effect by gaseous ozone, the humidity in the air is preferably about 70% or more. In the past, the operating water is sprayed into the gaseous ozone in a mist state to the operating water It has been used to generate ozone water by allowing gaseous ozone to be dissolved. However, since the existing ozone water generation method uses a method of simply injecting working water into gaseous ozone to dissolve it, its dissolved concentration is extremely low, and ozone is mixed in a bubble type having a relatively large size in ozone water. There are only a few cases that have a problem that its efficacy is extremely low.

In addition, as described above, since NOx compounds generated together with gas discharge during the generation of gaseous ozone are dissolved together in the working water and nitric acid is formed, the acidity of the working water increases, so a process of continuously adding a separate neutralizing agent. There was a problem that this was necessary.

First, it should be noted that, in the drawings, the same components or parts are denoted by the same reference numerals whenever possible. In describing the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as to avoid obscuring the subject matter of the present invention.

As shown in FIG. 1, the air purifier using the ozone water generator of the present invention has a main body 110, an oxygen supply device 120, an ozone generator 130, an ozone water generator 140, and a metal filter unit 150. , The gas-liquid separator 170 and the ozone water purification unit 180 are configured.

First, the main body 110 will be described. As shown in FIG. 1, the main body 110 includes a suction port 111 into which air containing a pollutant containing a malodorous component generated in an indoor space is introduced, and the pollutant is purified on the other side. An exhaust port 112 is formed to exhaust the air back to the indoor space. On the other hand, it is common that the air circulation means is further provided for the circulation of the working air, the air circulation means is any one of the inlet 111 side, the inside of the main body 110 or the exhaust port 112 side. Although it is possible to be installed in more than one place, it is preferable that the exhaust blower 190 is further configured to be further connected to the exhaust port 112, as shown in Figure 1 for the pollution prevention and stable operation of the air circulation means. Do.

On the other hand, the lower portion of the main body 110, the lower side of the metal filter unit 150 as shown in Figure 1 collecting water discharge port for collecting and discharge the ozone water containing the contaminant flowed down from the metal filter unit 150 114 is installed.

Next, the oxygen supply device 120 will be described. The oxygen supply device 120 has a function of supplying a high concentration of oxygen, as shown in FIG. As a result, as shown in Formula 2, it has a function of suppressing the generation of nitrogen oxides (NOx) generated together during ozone generation.

As an embodiment of configuring the oxygen supply device 120, various embodiments are possible, such as using an oxygen compression cylinder, and in one embodiment, the oxygen supply device 120 separates nitrogen and oxygen in the air. It is preferable to use a pressure circulation adsorption method for supplying a high concentration of oxygen.

Pressure circulation adsorption (PSA) is a process of separating and concentrating oxygen by using a difference in the amount of adsorption of oxygen adsorbed on the adsorbent according to the pressure. Since only compressed air and an adsorbent are used, it is easy to use without the emission of pollutants and has been widely used for medical oxygen concentrators for a long time.

The principle of concentration is to pressurize compressed air by injecting compressed air into a sieve bed filled with an adsorbent, so that the strong adsorbate is adsorbed and the weak adsorbate is concentrated, leaving oxygen and storing this oxygen separately as a product gas. The strong adsorbate adsorbed on the adsorbent is desorbed as internal oxygen, discharged to the outside, and depressurized.

The oxygen separation principle consists of a four-step process in which the two adsorption towers alternately perform the above process, and separates weakly adsorbed oxygen from a large amount of nitrogen, which is a strong adsorbent, in an adsorption tower containing zeolite, an adsorbent. .

Nitrogen, which is about 80% in the atmosphere, is more adsorbed by zeolite than oxygen, so when air enters the adsorption tower filled with adsorbent, the nitrogen is adsorbed and the oxygen is reduced to the upper outlet side of the adsorption tower. It is concentrated oxygen that is an adsorbate.

As the means for separating the oxygen, the above-described two-column-type oxygen separator is used. That is, it consists of an adsorption part which separates nitrogen and oxygen from air, an operation part related to air compression, storage, and outflow, a control part for opening and closing a valve, and a frame part for combining them.

Oxygen separation method of this device is to supply the compressed air to the adsorption tank filled with the adsorbent to adsorb the oxygen and to desorb the oxygen adsorbed from the adsorbent from the adsorbent to obtain the necessary oxygen at a constant concentration. At this time, some of the necessary oxygen obtained from the adsorption tank is refluxed and used for the desorption process.

The above adsorption process is a process of adsorbing nitrogen as a strong adsorbate by passing the pressurized air through a predetermined adsorbent to separate oxygen in the air. Once adsorption is performed, the nitrogen adsorbed to the zeolite as the adsorbent must be separated (desorbed). You should restore the original performance. This process recovers the adsorption capacity by recycling some of the oxygen adsorbed on the adsorbent in a low pressure state to desorb and recover the oxygen concentration and nitrogen, while obtaining concentrated oxygen with a certain purity.

Next, the ozone generator 130 is demonstrated. The ozone generator 130 has a function of generating gaseous ozone by decomposing oxygen supplied from the oxygen supply device 120 as shown in FIG. 1. In general, the ozone generating process is a method of electrolysis in which ozone is generated by passing oxygen through plasma discharge between two electrodes. Since the technology for constructing and operating the ozone generator 130 having the above-described function is a level of technology widely known and practiced in the technical field to which the present invention pertains, a detailed description thereof will be omitted.

Next, the water supply source 131 will be described. As shown in FIG. 1, the water supply source 131 has a function of storing and supplying operation water required for operation. On the other hand, as shown in Figure 1, the water supply source 131, it is preferable to supply the purified purified water through the ozone water purification unit 180, so that the operating water does not have to be additionally supplied frequently. Do. On the other hand, it is preferable that the external water source 132 is further connected to the water supply source 131 as shown in Figure 1 to be able to replenish the operating water shortage during operation.

Next, the ozone water generator 140 will be described. As shown in FIG. 1, the ozone water generator 140 generates liquid ozone water by mixing the operating water supplied from the water supply source 131 with gaseous ozone supplied from the ozone generator 130. Has As an embodiment of the ozone water generator 140 having such a function, a wide variety of embodiments are possible, and as an embodiment thereof, an ejector ejector 145 is included as shown in FIG. 2. It is preferable.

The ejector ejector 145 is a kind of pump that can eject water, steam, air, etc., which have pressure, and send the surrounding fluid to another place by spouting the highway at a spout. Has characteristics. In this case, the ozone water generator 140 has a first inlet 141 having a first working fluid drawn in to one side and a nozzle 142 formed at the other side thereof, and a second working fluid drawn in to the nozzle 142. It is installed on one side, the other side comprises an ejector (ejector) 145 including a suction chamber 144 is formed a diffuser 143, the first working fluid is the operating water or Any one of the gaseous ozone, and the second working fluid is preferably either the gaseous ozone or the operating water as opposed to the first working fluid.

Next, the metal filter unit 150 will be described. As shown in FIG. 1, the metal filter unit 150 is installed at the suction port 111 in the main body 110. As shown in FIG. 1, the metal filter unit 150 includes a first metal filter 151. The first metal filter 151 includes the first metal filter 151 as shown in FIGS. 1 and 3. As the ozone water supplied from the ozone water generator 140 flows down, contaminants in the air including pollutants passing through the metal filter unit 150 are collected in the ozone water and react with the ozone water to deodorize and It is purified while organic decomposition occurs. In addition, the temperature of the air containing the contaminants is also lowered. In this case, an embodiment in which the ozone water is supplied to the first metal filter 151 is possible in a wide variety of embodiments, and as an embodiment thereof, the first metal filter 151 is illustrated in FIG. 3. It is preferable to install the ozone water supply pipe 153 on the upper side of the. In this manner, the ozone water supplied from the ozone water generator 140 flows into the metal filter unit 150 so that the ozone water droplets are scattered in the air to the activated carbon filter in the filter unit 160 which will be described later. It is possible to prevent the droplets from accumulating and deteriorating the ozone purification efficiency and the air purification efficiency, thereby enabling a more efficient purification operation. In addition, the ozone water also has a function of controlling the temperature and humidity of the air containing the pollutant.

Meanwhile, as illustrated in FIG. 1, the metal filter unit 150 may further include one or more second metal filters 152, and may be mixed with air passing through the first metal filter 151. It is advisable to further collect and run down contaminants while filtering out any moisture present. In this case, a wide variety of embodiments are possible for the embodiments constituting the first metal filter 151 and the second metal filter 152, and the first metal filter 151 and the embodiment The second metal filter 152 may be configured by stacking a metal mesh material.

In addition, as shown in FIGS. 1 and 3, the ozone water flows in a curtain shape through the ozone water supply pipe 153 installed in front of the first metal filter 151 and connected to the ozone water generator 140. It is preferable to further include the ozone water discharge pipe 154 to lower, so that it is possible to wash off large pollutants in advance, so that more efficient pollutants can be removed. On the other hand, the ozone water flowing down through the ozone water discharge pipe 154 is preferably a curtain-wall shape by adjusting the flow rate and flow rate, so that the droplet of the ozone water does not occur.

On the other hand, as another embodiment constituting the metal filter unit 150, as shown in Figures 4 to 7, the metal filter unit 150, the mesh grid-shaped through hole through which fluid can pass A plurality of dust collecting screen plates 10 are formed so that fluid containing contaminants, such as dust, to be introduced may be deflected in one direction at an angle of 30 ° to 60 ° to pass through the through hole 11. It is preferable to include a metal filter screen (S) that is configured to include one or more). In this case, the metal filter screen S is generally constructed by stacking about 5 to about 20 dust screen plates 10.

The larger the deflection angle of the fluid passing through the through hole 11 is, the smaller the pressure drop of the fluid passing through the through hole 11 becomes, but the dust collecting effect due to the impact is lowered. The collecting effect is better, but the deterioration of the wall of the passing fluid becomes worse. Therefore, the deflection angle is preferably in the range of 30 to 60 degrees, and most preferably 45 degrees as shown in Fig.

The shape and size of the through-hole 11 can be changed into a very wide variety of embodiments. In one embodiment, as shown in FIG. 4, The width A of the band constituting the through hole is 2.25 mm and the opening angle D of the through hole 11 is in the vicinity of 110 DEG .

The method of manufacturing the dust-collecting screen plate 10 such that a plurality of the through-holes 11 are arranged is also possible according to a very wide variety of embodiments. In one embodiment, as shown in FIGS. 4 and 7, As shown, it is preferable that a plurality of the through holes 11 are formed by press-working a metal material in the form of a plate.

In this case, the dust screening plates 10 are arranged at an angle of 85 ° to 95 °, 175 ° to 185 ° with respect to the deflection direction of the dust screening plate 10 previously installed, as shown in FIG. 4 or FIG. Or a deflection direction of 265 ° to 275 °. In this arrangement, it is possible to minimize the pressure drop of the fluid passing through each of the dust screen plates 10 and to maximize the dust collecting efficiency while maximizing the traveling path.

Further, the plurality of dust screening plates 10 may further include a space 12 between their mounting positions as shown in FIG. 8 so that the fluid once passed through one dust screening plate 10 It is preferable that the direction of the flow can be made uniform to some extent before it is introduced into the dust screening plate 10 arranged next. In this case, the spacing of the space portions 12 can be implemented in a very wide variety of embodiments, and it is generally sufficient to have an interval of 1 mm to 10 mm.

Meanwhile, contaminants or dust collected on the surface of the dust collecting screen plate 10 are immediately washed down by the ozone water flowing to the surface of the dust collecting screen plate 10, so that no separate dust collecting operation is required. .

In order to allow the ozone water to flow down to the metal filter unit 150, the ozone water may be supplied through the metal filter unit 150.

To this end, the present invention, as shown in Figure 11, is installed in the center of the suction port 111, the ozone water supplied from the gas-liquid separator 170 of the fine droplets on the front surface of the metal filter unit 150 The front ozone water spray nozzle 155 spraying uniformly in the shape, the spray diffusion chamber 156 further formed on the upper surface of the metal filter unit 150 of the main body 110, and the spray diffusion chamber 156 One or more upper sides are installed along the installation direction of the metal filter unit 150, and the ozone water supplied from the gas-liquid separator 170 is uniformly sprayed onto the upper portion of the metal filter unit 150 in the form of fine droplets. The upper ozone water injection nozzle 157 is preferably configured to further include.

On the other hand, when the flow rate of the gas is increased by treating a relatively large flow rate in order to increase the purification efficiency per unit time, there is a possibility that the droplets passing through the metal filter unit 150 due to a high flow rate, the activated carbon unit 160 There is a fear that the operating efficiency of the. In order to prevent this problem, the present invention, as shown in Figure 11, the induction partition which is installed so that the lower portion between the metal filter unit 150 and the filter unit 160 inside the main body 110 ( 158 and a separation partition 159 installed at an upper portion of the main body 110 at the rear of the induction partition 158 so as to be opened at the front of the separation partition 159. One or more intervals are installed at one or more intervals in the vertical direction toward the front, so that the droplet collection partition 159a having at least one liquid passage hole 159b is formed at a portion connected to the separation partition 159. In addition, even when the gas velocity increases, it is possible to efficiently collect and remove droplets that can pass through the metal filter unit by the droplet collection partition 159a by the high velocity. Preferable.

Next, the filter unit 160 is demonstrated. As shown in FIG. 1, the filter unit 160 is installed at the exhaust port 112 in the main body 110 and includes one or more activated carbon filters 161 and 162 and a dustproof filter 165. .

In this case, the filter unit 160 has a function of adsorbing deodorizing and containing contaminants, and decomposes ozone contained in the air by using a carbon component contained in activated carbon as shown in the following Formula 3 It also has a function of preventing ozone from being released to the outside.

Figure 112013021449299-pat00005

On the other hand, the dustproof filter 165 is preferably to use a material having a sterilization effect in addition to simply collecting the fine dust remaining in the air. The dustproof filter having a sterilizing effect as described above is a technique widely known and practiced in the technical field to which the present invention pertains, such as an air conditioning facility of a medical institution such as a hospital, and thus, detailed description thereof will be omitted.

Next, the gas-liquid separator 170 will be described. As shown in FIG. 1, the gas-liquid separator 170 may temporarily store the liquid ozone water generated by the ozone water generator 140 to separate gaseous ozone that has not been dissolved. The liquid ozone water generated in the ozone water generator 140 by the gas-liquid separator 170 separates the liquid ozone water and gaseous ozone that has not been dissolved through the gas-liquid separator, so that the ozone water is the metal filter unit. Since the ozone can be used to purify the air through 150, and the gaseous ozone can be used separately for use in purifying the ozone water containing the pollutant flowing down through the metal filter in the ozone water purification unit 180, In addition to increasing efficiency, the amount of gaseous ozone introduced into the main body 110 may be reduced so that the ozone is not contained in the air passing through the filter unit 160 so that the ozone is not discharged to the room. It becomes possible.

On the other hand, when the air purifier 100 using the ozone water generator of the present invention is not operating for a variety of reasons (for example, failure of the exhaust fan, etc.), ozone gas is introduced through the inlet 111. There is a risk of leakage to the outside. In order to prevent such a situation, the air purifier 100 using the ozone water generator of the present invention is preferably configured to include one or more sensors 195 installed inside the main body 110, as shown in FIG. . In this case, the sensor 195 may be configured to include one or more of various sensors such as a pressure sensor, a pollutant concentration sensor or an ozone concentration sensor. When the sensor 195 includes a pressure sensor, when the pressure measured by the sensor 195 is out of the normal operating pressure range, the blocking shutter 115 is operated and the exhaust blower 190 is operated. It is preferable to further include a main control device 196 to stop the operation of, so as to prevent the leakage of ozone to the outside of the device.

On the other hand, the present invention uses the principle that ozone and pollutants cause various chemical reactions for the purification of pollutants. However, in the case of the purification function through the chemical reaction, the amount of ozone participating in the reaction depends on the concentration of the pollutant reacting. That is, when the concentration of the pollutant is high, the amount of ozone participating in the reaction increases, and when the concentration of the pollutant is low, the amount of ozone participating in the reaction decreases, thus increasing the amount of unreacted residual ozone. do. In extreme cases, when there is no contaminant in the inhaled air, since there is no ozone participating in the reaction, the ozone contained in the supplied ozone water remains as unreacted residual ozone. In this case, the ozone of the filter unit 160 There is a possibility that unreacted residual ozone that exceeds the decomposition capacity and rate is released to the outside. In order to solve this problem, in the present invention, the sensor unit 195 is further configured to include an ozone concentration sensor, the main control unit 196 is the ozone according to the concentration of ozone measured by the sensor unit 195 It is preferable to further have a function of adding or subtracting the operating amount of the generator 130. That is, by measuring the ozone concentration before, during, and after the passage of the metal filter unit 150, the filter unit 160, by adjusting the operating amount of the ozone generator 130 according to the measured ozone concentration, the ozone generator Preferably, the amount of ozone generated at 130 is used in a chemical reaction to purify most contaminants or at least through the filter unit 160 to be completely degradable. As described above, the concentration of ozone remaining after the reaction is sensed according to the concentration of the contaminant introduced therein, thereby controlling the amount of ozone water generated, thereby preventing the release of any unreacted ozone gas.

In this case, the sensor unit 195 may also measure the concentration of the pollutant introduced therein, and the main controller 196 may refer to the concentration of the pollutant measured by the sensor unit 195 to the ozone generator ( It is desirable to have a function of adding or subtracting the operating amount of 130) to prevent the discharge of unreacted ozone gas more accurately and efficiently.

Next, the ozone water purification unit 180 will be described. The ozone water purification unit 180 is separated from the gas-liquid separator 170 while storing the ozone water containing the pollutant discharged from the water collecting outlet 114 for a predetermined time, as shown in FIG. The gaseous ozone supplied through 181 is bubbled into the ozone water to have a sufficient time to purify the pollutants. In this process, the gaseous ozone purifies the ozone water containing the pollutant and at the same time a large portion of the ozone water is dissolved. In other words, it performs the function of mixing and dissolving the operating water and gaseous ozone secondary. In this case, when the volume of the ozone water purification unit 180 is increased to some extent, the ozone water stays in the ozone water purification unit 180 for a sufficient time, so that a sufficient amount of gaseous phase is obtained through the bubbling process. Ozone is dissolved in the ozone water. Meanwhile, some of the gaseous ozone that is not dissolved through the bubbling process and exits the ozone water surface is shown in FIG. 1 through the ozone discharge pipe 183, and the filter unit 160 inside the main body 100. ) Is discharged forward to decompose as shown in Formula 3. Therefore, it is possible to make almost no ozone discharge in the room.

On the other hand, the ozone water purification unit 180 circulates the operating water for circulating the ozone water purification filter 185 for purifying the ozone water and the purified ozone water to the operating water and supplying it to the water supply source 131. Preferably, the pump 186 is further included. In this case, since the gaseous ozone is partially dissolved in the ozone water supplied to the water supply source 131 through the working water circulation pump 186, the generation efficiency of ozone water can be further increased.

In this case, the ozone water purification filter 185 is preferably configured to further include any one or more of a demister filter, a containing pollutant water cleaning filter, or an activated carbon filter for adsorbing and purifying contaminants.

Meanwhile, as shown in FIG. 1, the ozone water purification unit 180 discharges sludge installed to be opened and closed under the ozone water purification unit 180 so as to discharge the contaminant sludge accumulated in the ozone water purification unit 180. Preferably, the ball 184 is further included.

In this case, the pollutants contained in the ozone water containing the pollutant discharged from the catchment outlet 114 may include various pollutants, and among these pollutants, dissolved pollutants dissolved and dissolved in the ozone water. In addition to the substance, there are also non-contaminant pollutants in a state in which they are not dissolved in the ozone water. These non-zone-contaminants can be classified into low specific gravity (L) which can be floated on the surface of the ozone water because they have a specific gravity smaller than that of the ozone water, and high specific gravity (H) which has a specific gravity greater than the ozone water and precipitates below the ozone water. Can be. As described above, when the non-concentration pollutant including the low specific weight material L or the high specific weight material H cannot be efficiently treated in advance, purification or bubbling operation in the ozone water purification unit 180 may be performed. There arises a problem that the purification efficiency of ozone water through the filter 185 may be reduced.

In order to prevent this problem, as shown in FIG. 10, the ozone water purification unit 180 is introduced from the water level control partition 187 installed at the bottom of the ozone water purification unit 180 and the water collecting outlet 114. The ozone water containing contaminants is installed to form an inclined surface 188a from an upper surface of the ozone water purification unit 180 so that the ozone water is guided down and the lower portion forms an extended partition portion 188b and the ozone water purification unit 180. It is preferable to further include a separating partition plate 188 extending below the extension surface (a) of the bottom of the. In this case, below the separation partition plate 188, as shown in FIG. 10, below the bottom of the ozone water purification unit 180, a precipitation unit 189 in which the high specific gravity material H is precipitated is further installed. It is desirable to.

Meanwhile, when the ozone water purification unit 180 further includes the water level control partition 187, the separation partition plate 188, and the precipitation unit 189, the sludge discharge means 184 is illustrated in FIG. 10. As shown, it is preferable to be installed in the precipitation section 189.

In this case, in the space between the extended partition wall 188b and the ozone water purification unit 180, the ozone water purification unit may be discharged so as to discharge the low specific gravity L, which is suspended and collected on the water surface of the ozone water W ( One side of the 180 is preferably configured to further comprise a low specific gravity material discharge means 191 is installed. On the other hand, the low specific gravity material (L) is collected by more than a predetermined amount is configured to further include a low specific gravity material detection sensor 192 for detecting this, the main controller 196 is the low specific gravity material detection sensor ( If it is detected that the low specific gravity material (L) is collected and suspended in a predetermined amount of more than 192 it is to have a function to discharge the low specific gravity material (L) by operating the low specific gravity material discharge means 191 desirable.

Air purifier 100 using the ozone water generator according to the present invention can be used for the purification of various contaminants, one example is isopropyl alcohol (IPA :) that can occur a lot in a nursing facility or a semiconductor manufacturing facility, such as a hospital Purification by the decomposition of isopropyl alcohol).

The isopropyl alcohol is an aliphatic saturated alcohol that is an isomer of propanol. Colorless, flammable liquid with a characteristic odor. Widely used as a solvent and cleaning liquid. The isopropyl alcohol is decomposed into acetone and water by the ozone water through a chemical reaction as shown in the following formula (4).

Figure 112013021449299-pat00006

In this case, acetone in the reaction product is generally not known to cause irritation symptoms in humans even after exposure to 500 ppm in air for 2 hours. Carcinogenicity and mutagenic chemicals are difficult to see. As it is considered to be absent, it is used in various consumer products such as processed foods from cosmetics, and is evaluated as a material generally recognized as safe when used in an acetone concentration in the range of 58 mg / L.
