Description


[0001] The present invention relates to a malodor and pesticide counteractant agent and the fabrication method thereof, particularly to a counteractant agent including its fabrication method that can effectively decompose pesticides, malodors, and smokes.

[0002] To prevent pest attacks, farmers usually spray pesticides on crops, such as vegetables, fruits, and tea trees. However, most pesticides, such as Malathion, Iprodine (an organonitrogen/heterocyclic pesticide widely used for strawberries), and Pyridaben (widely used for tea trees) are hazardous toward human health. Because pesticides are often organic compounds and water insoluble, it is difficult to remove them with water. As a result, a portion of pesticide residues usually remains on the surface of the vegetables, fruits, and tea leaves. Overdose of pesticide makes farmers sick, vomit, or harmful to their cranial nerve. The pesticides accumulated in the body induce genetic mutations and could lead to cancer. The phenomenon of "Cancer Village" appearing in Mainland China results from the residual pesticides in the foods, which were eaten by the villagers over a long period of time.

[0003] For crops not harvested by farmers in the safe dates, the problem of pesticide residues may become serious. As a consequence, the consumers would be harmed seriously. For example, the residual pesticides in tea leaves may be partially dissolved into hot water and thus jeopardize consumer's health. Consumers usually rinse vegetables and fruits with water; yet the cleaning efficiency is poor. Sometimes, consumers wash vegetables and fruits with saline water; however, the efficacy is lack of a scientific proof and thus its effect is uncertain. For vegetables and fruits washed with a detergent, the surfactants and other chemicals in the detergent may remain on the surface of vegetables and fruits. They could bring about an odd smell and cause a secondary contamination.

[0004] Unpleasant smells often come from malodors and smokes. The sources of malodors are usually nitrogen- or sulfur-containing compounds, such as amine (body odor and perspiration odor), trimethylamine (fish odor), hydrogen sulfide (rotten egg smell), and methyl mercaptan (kitchen garbage odor). The smoke often comes from cigarette. The deodorants on the market generally function on the basis of the principles of covering malodor with good odor, absorbing malodor, or neutralizing the acidic/basic molecules of malodors. The odor-covering type deodorants can cover malodors, but they cannot decompose malodor molecules; therefore, the malodor still remains partially. The absorption type deodorants are limited by their absorption capacity. When malodor is too intense or after the deodorants have been used for a long period of time, the absorption capability of deodorants may be exhausted. The acid-base neutralizing type deodorants can only be applied to the compounds that possess acidic or basic property. Some special types of deodorants, such as citric acid and maleic acid, cannot be used to eliminate mercaptan-based odors.

[0005] Smoke pollution includes cigarette, barbecue, kitchen smokes, etc. The primary constituent for cigarette smoke is nicotine, for barbecue smoke is acrylamide, imidazole, and quinoline as well as for kitchen smoke is usually indene, naphthalene, and phenanthrene. For further information, please refer to: Borgerding, M.; Klus, H. Experimental and Toxicologic Pathology 2005, 57, 43-73; Brage, C.; Yu, Q.; Chen, G.; Sjostrom, K. Biomass and Bioenergy 2000, 18, 87-91; Preuss, R.; Angerer, H.; Drexler, H. Int. Arch. Occup. Environ. Health 2003, 76, 556-576. All of the smokes mentioned above are hazardous to human body; however, so far on the market, there is no appropriate agent that can effectively decompose the primary constituents of smokes.

[0006] A few current technology can effectively decompose pesticides, malodors, or smokes, the heath of people is being threatened thereby. Accordingly, the present invention discloses a malodor and pesticide counteractant agent and a fabrication method thereof, whereby the molecules of pesticides, malodors, and smokes can be decomposed as soon as those molecules contact the agent of the present invention.

[0007] The primary objective of the present invention is to provide a malodor and pesticide counteractant agent and a fabrication method thereof, wherein the agent of the present invention can be fabricated into an aerosol, a detergent, or an additive and used to decompose pesticides, malodors, and smokes.

[0008] Another objective of the present invention is to provide a malodor and pesticide counteractant agent and a fabrication method thereof, wherein the detergent fabricated according to the present invention can be used to clean the residual pesticides on crops, particularly vegetables and unpeeled fruits.

[0009] The other objective of the present invention is to provide a malodor and pesticide counteractant agent and a fabrication method thereof, wherein the aerosol fabricated according to the present invention can effectively decompose the residual pesticides on crops. The aerosol of the present invention can be used to eliminate body odors, such as underarm odor, perspiration odor, sole odor, bad breath, hair odor, menstrual odor as well as odors of animals and pets. The aerosol of the present invention can be applied directly on daily necessities, air filters, clothes, respirators, masks, gloves, protective clothes, condoms, and medical devices. The aerosol can also be applied to the spaces polluted by odors or smokes, such as the interior and exterior of living rooms, vehicle compartments, fish bowls, bathrooms, restaurants, hotels, kitchens, barbecues, cybercafés, and smoking areas.

[0016] Below, an embodiment is used to exemplify the fabrication method of the agent of the present invention. Thereby, the person skilled in the art would fully understand and make use of the present invention according to those described in the specification. However, the scope of the present invention is not to be limited by the exemplification anyhow.

[0017] The fabrication method of the present invention includes the following steps:

Step 1, preparing Constituent (A): 0.50 grams of ammonium nickel sulfate is added into 500 mL of Reverse Osmosis (R.O.) water, and the solution is stirred for 15 min at the ambient temperature until the solution is clear and does not contain any deposition.

Step 2, preparing Constituent (B): 15 grams of sodium hydrogen phosphate and 15 grams of sodium dihydrogen phosphate are sequentially added into 9.0 L of R.O. water, and the solution is fully stirred; then, 120 g of sodium chloride, 40 g of potassium hydrogen carbonate, 5.0 g of calcium sulfate, and 5.0 g of magnesium chloride are sequentially added into the solution, which is quickly stirred for 60 min at the ambient temperature until no suspended matter appears.

Step 3, preparing Constituent (C): 10 mL of 3.0% hydrogen peroxide is added into 500 mL of R.O. water, and then 5.0 g of a quinone derivative is added into the solution; the solution is stirred for 30 min at the ambient temperature until the solution is homogeneous; 2.0 g of coenzyme NADPH is added into the solution, and the solution is stirred for 20 min until the solution is clear.

Step 4: Constituent (A) is added into Constituent (C), and the solution is stirred for 15 min at the ambient temperature; subsequently, Constituent (B) is added into the solution of Constituent (A) and Constituent (C), and the solution is fully stirred for 20 min; thus, the agent of the present invention is obtained. The agent should be packed in airtight containers, which have a cap or a jet nozzle, and it is preferred that no air exists in the container. The agent of the present invention can be sprayed onto the surface of objects or into the 3-dimensional space of the surroundings, and the concentration of the agent in the aerosol solution is preferred to be 10-4~10-6 wt%. When the agent of the present invention is used as a detergent or an additive, the concentration in the washing solution is higher than that in the aerosol solution and is preferred to be 10-1~10-4 wt%.



[0018] The technical contents have been stated above. Three experiments for verifying the efficacies of the agent of the present invention in decomposing pesticides, odors, and smokes are to be described in detail below.

Experiment 1



[0019] Experiment 1 is to verify the efficacy of the agent fabricated according to the abovementioned embodiment in decomposing pesticides; tap water and a 10% salt solution are used for comparison of the decomposing rate in the this experiment. The pesticides tested in this experiment include seven groups of pesticides with the total number thereof amounting to 17 compounds. The pesticides tested in this experiment include: organophosphorous pesticides, such as Diazinon, Terbufos, Acephate, Glyphosate, Phosmet, and Mevinphos; organonitrogen/heterocyclic pesticides, such as Benomyl, Metalaxyl, and Pymetrozine; carbamate pesticides, such as Methomyl, Fenobucard, and Carbendazim; urea-type pesticides (herbicides), such as Pencycuron; triazole pesticides, such as Hexaconazole; dithiocarbamates pesticides (germicides), such as Thiophanate-methyl and Cartap; and other type pesticides, such as Thiabendazole.

[0020] The structural formula of the abovementioned pesticides are shown below:
  1. A. Organophosphorous pesticides



  2. B. Organonitrogen/Heterocyclic pesticides

  3. C. Carbamate pesticides

  4. D. Urea-type pesticide

  5. E. Triazole pesticide

  6. F. Dithiocarbamates pesticides

  7. G. Other type pesticide



[0021] In this experiment, 10 mL of the agent of the present invention and 10 mL of a 10 ppm solution of each abovementioned pesticide are mixed to react for 5.0 min. Then, High Performance Liquid Chromatography (HPLC) is used to determine the extents of the pesticide decomposition. Tap water and a 10% salt solution are also allowed to react with the same pesticide solutions. The experimental results of tap water and the 10% salt solution are used to compare with the experimental results of the agent of the present invention. From the experimental results, it shows that the agent of the present invention has a superior decomposing effect on pesticides. The decomposing rate of the agent of the present invention is 2,300~14,000 times than that of tap water and is 1,900~11,000 times than that of 10% salt solution. Therefore, the effect of the present invention in decomposing pesticides is much greater than other conventional methods.

[0022] Fig. 1 and Table 1 indicate that the agent of the present invention can indeed decompose pesticides. Among these seventeen pesticides, the agent of the present invention exhibits the best decomposition results on Terbufos, Acephate, and Hexaconazole.

Experiment 2



[0023] Experiment 2 is to verify efficacy of the agent fabricated according to the abovementioned embodiment in destroying the molecules of malodors. The decomposing rates are compared in this experiment. The nitrogen- and sulfur-containing compounds, which have strong odor, are used as targeting samples, such as Terbufos, Diazinon, Hexaconazole, and Fenobucard. The structural formula of these odor compounds are shown below:





[0024] In this experiment, 7.5 mL of a 10 ppm solution of the nitrogen-or sulfur-containing odor compound is allowed to react with 2.5 mL of the agent of the present invention for 1.0 min, 3.0 min, and 5.0 min, respectively. HPLC is used to determine the destruction extents of odor compounds and the results are shown in Fig. 2.

[0025] Fig. 2 shows that the agent of the present invention can effectively decompose the nitrogen- or sulfur-containing odor molecules of Terbufos, Diazinon, Hexaconazole, and Fenobucard in 1.0 min, 3.0 min, and 5.0 min, respectively. After 5.0 min of the reaction time, the agent of the present invention destroyed 91% of Terbufos, 87% of Diazinon, 85% of Hexaconazole, and 76% of Fenobucard. Therefore, the agent of the present invention can indeed decompose odor molecules in an efficient way.

Experiment 3



[0026] Experiment 3 is to verify the efficiency of the agent fabricated according to the abovementioned embodiment in destroying the primary molecules of smokes, and the decomposing rates are compared. In this experiment, nicotine, indene, and naphthalene are used as the testing samples. They respectively represent the major components in cigarette smoke, barbecue smoke, and kitchen smoke. The solutions with different concentrations of the agent of the present invention are used to react with nicotine-the primary constituent of cigarette-in order to obtain the destruction rates of different concentrations of the agent.

[0027] The primary constituents of the abovementioned smokes are shown below:
  1. A. Primary constituent of cigarette smoke

  2. B. Primary constituents of barbecue smoke

  3. C. Primary constituents of kitchen smoke



[0028] In this experiment, 9.9 mL of a 100 ppm solution of each abovementioned smoke constituent is allowed to react with 0.10 mL of the twenty times dilution and one hundred times dilution, respectively, of the agent of the present invention for 3.0 min; then Gas Chromatography (GC) was used to determine the extents of the remaining primary constituents of smokes. The experimental results are shown in Figs. 3 and 4.

[0029] Fig. 3 shows that the agent of the present invention decomposed the primary constituents of cigarette smoke (i.e., nicotine), barbecue smoke (i.e., indene), and kitchen smoke (i.e., naphthalene). The twenty times dilution of the agent of the present invention destroyed >90% the primary constituents of the abovementioned smokes in 3.0 min; especially, the destruction extent of the primary constituent of cigarette smoke-nicotine-was as high as 99%. Furthermore, Fig. 4 indicates that the agent of the present invention effectively decomposed nicotine in 2.0 min when the concentration of the agent of the present invention is twenty times diluted. Its destruction extent is >99%. Therefore, the agent of the present invention can indeed decompose the molecules of smokes efficiently.

[0030] In summary, when the molecules of pesticides, malodors, and smokes react with the malodor and pesticide counteractant agent of the present invention, these molecules were rapidly decomposed by the constituents of the agent of the present invention. Therefore, the present invention achieves the objectives of eliminating pesticides, malodors, and smokes.

[0031] These embodiments described above are to clarify the present invention to enable the persons skilled in the art to understand, to make, and to use the present invention. However, it is not intended to limit the scope of the present invention, and any equivalent modification and variation according to the scope of the present invention is to be also included within the scope of the claims of the present invention.
