The present invention uses a pyrethroid insecticide, a dye and 2,5
- This relates to an electric mosquito repellent mat characterized by containing di-tertiary butylhydroquinone. Its purpose is to stabilize pyrethroids and dyes. Conventionally, BHT was used as a pyrethroid stabilizer in electric mosquito repellents, but in order for the stabilizer to be effective, it had to be used in a fairly large amount, and the effect was not sufficient. Furthermore, dyes are added to electric mosquito repellent mats in order to determine how much active ingredient remains when they are used, and the color gradually fades with use, but dyes that have this effect are not chemically stable. It had the disadvantage that it changed color during storage due to its poor quality, and there was no effective dye stabilizer. The present invention provides excellent stabilizing effect on both pyrethroids and dyes by using a very small amount of 2,5-di-tert-butylhydroquinone, and is very economical and has excellent stability. This is an excellent invention. The pyrethroid insecticides used in electric mosquito repellents include allethrin and its isomer 3-allyl-2-methylcyclopent-2-en-4-one-1-yl.
d-cis/trans-chrysanthemate (hereinafter d
- allethrin), 3-allyl-2-methylcyclopent-2-en-4-one-1-yl d-trans-chrysanthemate (hereinafter referred to as bioallethrin), d-3-allyl-2- Methylcyclopent-2-en-4-one-1-yl d-trans-chrysanthemate (hereinafter referred to as esbioallethrin), 5-propargyl-
Examples include 2-furylmethyl d-cis/trans-chrysanthemate (hereinafter referred to as d-flamethrin). All of these can be made more effective by incorporating a pyrethroid synergist. Furthermore, with electric mosquito repellents, the active ingredients used overnight are heated from the beginning, so much of it evaporates in the early stages, and the effectiveness decreases towards the end. toxide,
By adding an appropriate amount of octachlorodipropyl ether and a compound that controls the volatilization of pyrethroid such as diethyl toluamide or squalane, glycerin fatty acid ester, butyl stearate, etc., the amount of volatilization of the active ingredient over time can be reduced from 8 to 10 hours. The time can be kept almost constant and constant efficacy can be obtained. The dyes added to the electric mosquito repellent of the present invention for the purpose of determining the presence or absence of residual active ingredients are oil-soluble dyes such as 1,4-dibutylaminoanthraquinone and 1-methylamino-4-orthotolylaminoanthraquinone. . These dyes can be applied to impregnated pulp boards at 150-160°C.
When heated, the color was initially bright blue, but as the heating time progressed, the color gradually faded, and after 8 to 10 hours, the color completely faded and became colorless. At that point, almost no active ingredient remains on the pulp board, making it possible to determine the presence or absence of the active ingredient.
However, these dyes have low stability against light and air during storage, and it takes at least six months, or more than a year, from production to actual use. It is conceivable that there will be unused and unsold items at stores, and these items will be stored for a long period of two years or more. In such cases, depending on the storage conditions, the dye impregnated into the pulp board may fade or change color from the color it was colored at the time of manufacture, making it impossible to determine the presence or absence of active ingredients. , the product value will be completely lost. As a result of repeated research to compensate for these shortcomings, the present inventor has developed 2,5-ditor, which is one of the antioxidants.
This invention was completed by discovering that fading and discoloration of these dyes during storage can be prevented by adding shary-butylhydroquinone (hereinafter referred to as DBH). this
Special Publication in 1977 as an insecticidal composition using DBH
There is No. 24796, but this is added to mosquito coils for the purpose of enhancing the insecticidal efficacy, and the intention is completely different from the present invention. Furthermore, when we examined the insecticidal efficacy of electric mosquito repellents with and without DBH, we found that there was no difference, and no enhancement effect like that of light news was observed in electric mosquito repellents.
However, in the time-course test, no fading or discoloration was observed in the products to which DBH was added, and the products with DBH added did not show any fading or discoloration.
Addition of di-tert-butyl-4-hydroxytoluene (hereinafter referred to as BHT) or butylhydroxyanthol (hereinafter referred to as BHA) did not prevent the fading and discoloration of the dyes. Next, the present invention will be explained with examples. Example 1 Allethrin 8g, piperonyl butoxide 4g
g, 1 g of DBH, and 0.10 g of 1,4-dibutylaminoanthraquinone were dissolved in acetone to make 100 ml, and 1 ml of this was adsorbed onto a pulp board and dried to obtain an electric mosquito repellent mat. Example 2 3 g of d-Furamethrin, 10 g of piperonyl butoxide, 1.5 g of DBH and 1-methylamino-4
- Dissolve 0.10 g of orthotolylaminoanthraquinone in acetone to make 100 ml, adsorb 1 ml onto a pulp board, and dry to obtain an electric mosquito repellent mat. Example 3 4 g of d-allethrin, 4 g of butyl stearate
g, 2 g of DBH and 0.08 g of 1,4-dibutylaminoanthraquinone are dissolved in acetone to make 100 ml, and 1 ml of this is adsorbed onto a pulp board and dried to obtain an electric mosquito repellent mat. Example 4 S-bioallethrin 2g, squalane 3g,
1 g of DBH and 0.10 g of 1-methylamino-4-orthotolylaminoanthraquinone are dissolved in acetone to make 100 ml, and 1 ml of this is adsorbed onto a pulp board and dried to obtain an electric mosquito repellent mat. Next, the results of a test on the electric mosquito repellent of the present invention over time will be shown. Test Example 1 The electric mosquito repellent mats shown below were prototyped, placed one by one in a polyethylene bag, stored in a thermostat at 40°C, taken out after a specified period of time, and the active ingredients of each electric mosquito repellent mat were tested. The amount was quantified.

[Table] As shown above, even when the electric mosquito repellents A, C, E, and G of the present invention are stored at 40°C for one year, there is very little loss of active ingredients, and no change in the color of the dye is observed. Ta. On the other hand, in the case of BHT-added pine, the DBH
Although 4 to 8 times the amount of dye was added, the amount of active ingredients decreased significantly, and the color of the dye had faded or changed after one year. Therefore, it is clear that the electric mosquito repellent mat of the present invention is an excellent mat whose active ingredients and dyes do not change over time. Test Example 2 An electric mosquito repellent with the following formulation was prototyped,
Place each electric mosquito repellent in a polyethylene bag and store it at room temperature (under scattered light) and in a thermostat at 40°C (in the dark). After a specified period of time, remove each electric mosquito repellent to check for fading or discoloration. Examined.

[Table] As shown above, BHT or BHA of A, B and D
In contrast to the dye fading and discoloration of the electric mosquito repellent added with DBH after 6 months at room temperature and after 3 months with B at 40°C, the electric mosquito repellent C and E with the addition of DBH of the present invention No change was observed in commercial pine under storage conditions of room temperature and 40°C even after one year. Furthermore, when mats C and E were analyzed to determine the amounts of d-allethrin and d-flamethrin, there was no significant difference from the values in the trial production of mats, and it was confirmed that the active ingredients were stable. Therefore, the present invention is an advantageous invention that can prevent the reduction of active ingredients over time as well as the discoloration and fading of dyes. Next, A, C, D and E, which were prototyped in the above test example.
Electric mosquito repellent pine mats were placed on a heating element heated to 160°C and changes in color tone were observed with the naked eye.The color of each pine began to fade after 6 hours, and became colorless after 10 hours. Furthermore, when the amount of active ingredient was analyzed at that point, it was found that the remaining amount was very small and it was clear that it could not be used again. As described above, the pine containing DBH of the present invention causes the dye to change over time, but does not prevent the dye from fading during actual use.
