Description

The present invention relates to an improvement of a mosquito coil.

Mosquito coils are mainly used to combat adult mosquitoes, and have long been popular as an indispensable item in summer in ordinary households. The mosquito coil was devised in 1890, and at that time the rod was about 30cm long and the burning time was about 1 hour, but after that the shape of the mosquito coil was changed from a rod to a spiral. Also, the burning time for one bottle was about 7 to 8 hours according to the human bedtime. Mosquito coils are convenient to use anywhere in a single match, have a certain insecticidal effect until burned out, and are excellent in diffusing active ingredients with smoke. It can be said that this is a very rational insecticidal form.
Mosquito coils include incense base materials such as pyrethroid insecticides, flame retardants and extenders (vegetable powder, mineral powder, charcoal powder, etc.) and pastes (vegetable binder, starch, etc.) For example, after adding an aqueous solution containing a colorant to a mixed powder containing a fragrance and an antifungal agent, the mixture is kneaded, and then subjected to an extruder to form a plate-like sheet, punched into a spiral shape by a punching machine, and dried to a moisture content of about 7 to 10%. It is common to make them. As the colorant, malachite green is mainly used, and a green spiral incense that produces a cool feeling is mainly used.

By the way, some scented mosquito coils are known. For example, in Japanese Patent Application Laid-Open No. 10-167903, a fragrance component such as sandalwood extract or mandala extract is blended and burned from wood powder such as pine or cedar. Attempts have been made to mask the off-flavors and pungent odors that occur. However, as long as you use a lot of wood flour, even if you mix incense ingredients, it will remain in insufficient masking, and it will be difficult to realize a deep and pleasant fragrance, for example, a long-standing tradition of mosquito coils Met.
In other words, in order to give a scent suitable for a mosquito coil, it is necessary to select a fragrance ingredient suitable for the dosage form unique to mosquito coils with heating and smoke, and to thoroughly examine the combination with a scent base material However, the present situation is that no useful scented mosquito coils have been created yet.

JP-A-10-167903

An object of the present invention is to provide a useful scented mosquito coil that matches a mosquito coil.

The present invention has been found that the following constitution has an excellent effect for achieving the above-mentioned object.

Since the mosquito coil of the present invention has selected a fragrance component suitable for the dosage form unique to the mosquito coil and optimized the combination with the incense base material, the mosquito coil has been given a suitable scent. Its practicality is extremely high.

The mosquito coil of the present invention uses a pyrethroid insecticide from the viewpoint of insecticidal efficacy and safety as an active ingredient. Examples of pyrethroid insecticides include pyrethrin, allethrin, framethrin, praretrin, empentrin, terrareslin, transfluthrin, metfurthrin, profluthrin, 4-methoxymethyl-2,3,5,6-tetrafluorobenzyl 2,2,3,3 -Tetramethylcyclopropanecarboxylate and the like can be mentioned, but not limited thereto. In addition, when the optical structure or geometric isomer based on an asymmetric carbon or a double bond exists in a chemical structure, of course, this invention includes each single and arbitrary mixtures.
As content of a pyrethroid type insecticidal component, 0.005-2.0 mass% is preferable with respect to the whole quantity of a mosquito coil.

In the present invention, N- (2-ethylhexyl) -bicyclo [2,2,1] hept-5-ene-2,3-dicarboximide (hereinafter referred to as efficacy enhancer A) is used for enhancing insecticidal efficacy. ), A synergist such as piperonyl butoxide and Leesen 384 can also be added. The synergist may be added in an amount of 0.5 to 8.0 times the amount of the pyrethroid insecticide.

Examples of incense base materials include flame retardants and extenders (vegetable powder, mineral powder, charcoal powder, etc.) and pastes (vegetable binder, starch, etc.). In order to impart a suitable scent, at least one selected from pesticide chrysanthemum extract powder as vegetable powder, citrus skin powder, tea powder, coconut shell powder, and / or tab powder as vegetable binder Preferably used.
The tea powder as used in the present invention includes not only powder obtained by drying ordinary tea leaves, but also tea extract powder obtained by drying tea leaves obtained by filtering tea.
The incense incense substrate may be appropriately blended in the range of 1.0 to 99% by mass, preferably 10 to 60% by mass, and more preferably 20 to 50% by mass with respect to the total amount of the mosquito coil. Combined with the perfume ingredients, it is possible to realize a scent suitable for the mosquito coil, which is a feature of the present invention, for example, a “deep and pleasant scent”.
Of course, as long as it does not interfere with the gist of the present invention, for example, wood powder such as fir, toga, hinoki (vegetable powder), diatomaceous earth, clay, kaolin, talc, etc. (mineral powder), or Other flame retardants and extenders such as bare ash (charcoal powder), and other pastes such as starch, tapioca powder, carboxymethylcellulose (CMC), polyvinyl alcohol, and the like may be appropriately blended. In addition, as a result of the test, it was preferable that the blending amount of the wood flour was kept to 45% or less with respect to the total amount of the mosquito coil, and the use of pine and cedar was avoided.

The mosquito coil incense according to the present invention is characterized by containing a heat-diffusing fragrance having a boiling point of 250 ° C. or higher and 400 ° C. or lower as a fragrance along with the above components.
The heat-diffusion fragrance | flavor said by this invention means what has a property which a fragrance | flavor raises while spreading | diffusion in a wide range because a fragrance | flavor component volatilizes efficiently in the case of a heating.

In addition, when the said fragrance | flavor component is contained in essential oil, the essential oil is also included by this invention.

Among the above fragrance ingredients, galaxolide, musk ketone, hexylcinnamic aldehyde, ethylene brushate, methyl atrate, hexyl salicylate, tricyclodecenyl acetate, oranger crystal, ambroxan, cachemelan, caron, heliotropin, Dihydroindenyl-2,4-dioxane, indole, methyl cedryl ketone, methyl β-naphthyl ketone, methyl dihydrojasmonate, rosephenone, coumarin, vanillin, stylus resinoid, iso-i-super, benzylbenzoate, benzyl It is preferably at least one selected from salicylate, ionone, lilyaldehyde, and isolongifolanone.

Moreover, in this invention, the fragrance | flavor whose boiling point is less than 250 degreeC can further be contained, and it can comprise as a top note and middle note component of a heat | fever diffusion fragrance | flavor, or can adjust an incense tone.
For example, p-tert-butylcyclohexyl acetate, o-tert-butylcyclohexyl acetate, p-tert-pentylcyclohexyl acetate, benzyl acetate, phenylethyl acetate, styryl acetate, anisyl acetate, cinnamyl acetate, terpinyl acetate, Acetate compounds such as dihydroterpinyl acetate, linalyl acetate, ethyl linalyl acetate, citronellyl acetate, geranyl acetate, neryl acetate, bornyl acetate, and isobornyl acetate;

And monoterpene alcohols such as terpineol, geraniol, dihydromyrcenol, borneol, menthol, citronellol, nerol, linalool, ethyl linalool, thymol, phenylethyl alcohol, and eugenol, or aromatic alcohols having 10 carbon atoms,
Other examples include, but are not limited to, limonene, α-pinene, terpinene, methyl ionone, tonalide, anisaldehyde, and the like.

Furthermore, by blending “green scent” typified by cis-3-hexenol, it is possible to realize a scent suitable for a mosquito coil with a relaxing effect.
By the way, the burning part of the mosquito coils has a temperature of 700 to 800 ° C., but a temperature gradient is generated as the distance from the burning part increases, and the active pyrethroid insecticidal component evaporates from about 250 ° C., 6 to 8 mm before. It is known. Similarly, depending on the volatility of the fragrance component, it is estimated that the higher the volatility such as cis-3-hexenol, the more the volatilization component is volatilized without being subjected to thermal decomposition from the far lower temperature part. .

In addition to the above components, the mosquito coil of the present invention may contain additives such as antifungal agents, stabilizers, and coloring agents. Examples of the antifungal agent include dehydroacetate and sorbate, and a typical stabilizer is dibutylhydroxytoluene (BHT). In addition, malachite green is used as a colorant, and a green spiral incense that gives a cool feeling is the mainstream, but it is also practical to use a highly safe pigment that corresponds to a food additive. For example, a combination of edible blue No. 1 and edible yellow No. 4 and / or edible red No. 106 can be used to realize a green color instead of malachite green, or a yellow-green incense or a purple incense can be produced.

The mosquito coils of the present invention are mixed powder containing the above components and water with an aqueous solution containing a colorant, kneaded and then subjected to an extruder to form a plate-like sheet, punched into a spiral shape by a punching machine, and a moisture content of 7 to 10 In general, it is dried to about%. The pyrethroid insecticide component and / or the fragrance component may be contained by means of spraying, coating, dripping, dipping and the like after the incense sticking which does not include the pyrethroid insecticide component and / or the fragrance component.

The mosquito coil of the present invention obtained in this way has been given a `` scent of comfort '' suitable for the mosquito coil incense that has been familiar for many years while maintaining the insecticidal efficacy and quality of conventional mosquito coils. It has a high control effect against mosquitoes, flies, cockroaches, fleas, bed bugs, fly flies, chironomids, etc. Examples of the mosquitoes include Culex pipiens, Aedes albopictus, Chikaieka, Kodaka mosquito, Attaikaeka, Nukaka and the like.

Next, the mosquito coil of the present invention will be described in more detail based on specific examples, but the present invention is not limited to these.

dl, d-T80-alleslin 0.3 parts, potency enhancer A 0.7 parts, flame retardant and extender, pesticide chrysanthemum extract powder (vegetable powder) 35 parts, citrus skin powder (vegetable 8.0 parts of powder) and 32 parts of wood flour (plant-derived plant powder), 8.4 parts of tab powder (plant binder) and 15 parts of α-starch, heat diffusion As a fragrance, 0.06 part of a fragrance component (base note component having a boiling point of 250 ° C. or higher and 400 ° C. or lower) containing galaxolide, iso-super, hexylcinnamic aldehyde, etc., cis-3-hexenol, linalool and the like Containing fragrance ingredients (top note and middle note ingredients having a boiling point of less than 250 ° C.) in mixed powder containing 0.04 parts, colorants (food blue No. 1: 85%, food yellow No. 4: 10% and food red) 106: 5%, 0.3) 0.15 parts of sodium dehydroacetate as an antifungal agent and 100 parts of water are kneaded and then kneaded to form a plate sheet through an extruder, punched into a spiral mold by a punching machine, and dried to a moisture content of about 7 to 10% Thus, a green mosquito coil A was manufactured.

When the mosquito coil incense A of the present invention thus obtained was opened before use, it emitted a “scent of tranquility”, and no off-flavor or pungent odor was felt. And when I used it while sleeping in a 6 tatami room, this "comfort scent" lasted until the end of use and brought a sense of relaxation, and during that time I was not bothered by mosquitoes.

Mosquitoes manufactured by replacing only fragrance components (base note components having a boiling point of 250 ° C. or higher and 400 ° C. or lower) containing ethylene brushate, methyl atrate and hexyl salicylate, etc. Mosquito trap manufactured by replacing only the perfume component (base note component having a boiling point of 250 ° C. or higher and 400 ° C. or lower) containing tricyclodecenyl acetate, oranger crystal, cashmere lantern, etc. Mosquito trap manufactured by replacing only the fragrance component (base note component having a boiling point of 250 ° C. or higher and 400 ° C. or lower) containing heliotropin, dihydroindenyl-2,4-dioxane, indole, etc. Incense stick D, heating diffusion fragrance, methyl cedryl ketone, methyl β-naphthyl keto To prepare a rose phenone, and steel Lux resinoid like perfume ingredients including mosquito coil E which (boiling point below base note ingredients 400 ° C. 250 ° C. or higher) was prepared by replacing only. When these incense sticks were tested in a 6 tatami room like the mosquito coil Incense A, it was confirmed that the scent of "relaxedness" lasted in the same way and provided a feeling of relaxation while being not bothered by mosquitoes. done.

According to Example 1, various mosquito coils (shown in Table 1 with the same coloring agent, antifungal agent and water as in Example 1) shown in Table 1 were prepared, and the performance of the following items was evaluated. The results are shown in Table 2.
(1) Sensory test: Each test incense was burned in a glass cylinder having a diameter of 20 cm and a height of 40 cm, and a scent test was conducted by 10 panelists. The result was shown by the average value of the score with respect to a panelist's fragrance (the highest value of preference of fragrance was set to 10 and the minimum value was set to 1).
(2) Electroencephalogram measurement: Test incense sticks (present invention incense sticks 1 to 8, comparative example incense sticks 1 to 3) were each burned in a 6 tatami room. Five testers sit one by one in the center of the room, load the equipment, fast α wave, mid α wave (concentrated in a relaxed state), slow α wave, β wave (tension, anxiety, irritated) Time state) and θ waves were measured. For each brain wave, calculate the change in occupancy from the blank (normal state without using incense sticks), and obtain the change rate of mid α wave / change rate of β wave (average value of 5 people) to obtain the test incense stick We evaluated the degree of relaxation that can bring.

As a result of the test, the mosquito coil incense of the present invention containing a pyrethroid insecticidal component, an incense base material, and a heated diffusion fragrance having a boiling point of 250 ° C. or higher and 400 ° C. or lower is suitable for mosquito coil incense that has been familiar for many years. The scent was released and brought a sense of relaxation. This is supported not only by sensory tests but also by electroencephalogram measurements.
In the present invention, the incense stick 4 of the present invention contains a large amount of wood powder, and the incense stick 5 of the present invention does not contain tab powder, which tends to be slightly less effective in the present invention. From these facts, as incense stick base material, there are many blends of pesticide chrysanthemum extract powder as vegetable powder, citrus skin powder, tea powder, coconut shell powder, and / or tab powder as vegetable binder It has been found that the combination with a fragrance is more preferable.
In addition, the incense stick 5 of the present invention is obtained by adding a top note and middle note component having a boiling point of less than 250 ° C. to a heated diffusion fragrance having a boiling point of 250 ° C. or more and 400 ° C. or less as compared with the incense stick 6 of the present invention. It turned out to be more preferable.
On the other hand, as in Comparative Example 1, incense that does not contain a heat-diffusing fragrance, a highly-preferred “relaxing fragrance” cannot be obtained, and a large amount of essential oil mainly composed of a fragrance component of less than 250 ° C. Comparative Example 2 had a low numerical value of [change rate of mid α wave / change rate of β wave], and tended to cause anxiety and irritation. Furthermore, Comparative Example 3 was not mixed with the heat diffusion fragrance according to the present invention, and even when a fragrance having a boiling point of less than 250 ° C. was mixed, the wood powder-derived odor and irritating odor were strong.

The mosquito coil of the present invention is highly practical as an insecticide, and can be applied to other incense sticks such as Buddhist altars.
