Description

The present invention relates to a scented drug volatilizer.

Various insect repellents have been put to practical use in order to control or repel pests. In the past, sublimable insecticidal components such as p-dichlorobenzene and naphthalene have been used as active ingredients of insect repellents. However, since they emit a unique odor, they may be avoided by consumers depending on the usage environment. Accordingly, pyrethroid insect repellent components having low odor and having volatility at room temperature such as empentrin and profluthrin have been developed and widely put into practical use. However, in recent years, consumer needs have been diversified, and many products having fragrance have been marketed. Also in the field of insect repellents, scented products can easily be used due to the fragrance, so it is expected that consumer needs will increase in the future.

As a conventional insect repellent, for example, the chemical volatilization body described in Patent Document 1 is held in a state where the insect repellent component is kneaded in the resin carrier, and therefore the transpiration material of Patent Document 2 and Patent Document 3 described later Compared to the above, there is a feature that the volatilization of the insect repellent component can be stably and gradually released.
On the other hand, the transpiration | evaporation material of patent document 2 uses a short fiber and a long fiber as a volatile body which hold | maintains the transpiration | evaporation component comprised from an insecticide, a repellent, etc., and has provided the vent hole in the said volatile body. It is said that the volatilization body having such a configuration increases the amount of transpiration component retained, and can further volatilize the volatile component over a long period of time, but when compared with the type of Patent Document 1 It is difficult to gradually release the transpiration component, and as a transition of the volatilization state, there is usually a tendency that it is somewhat higher in the initial stage and lower in the later stage.

Further, a transpiration material for controlling pests by holding a transpiration component as described above in a knitted fabric formed of a liquid absorbent filament yarn is also known (see, for example, Patent Document 3). In the transpiration material of Patent Document 3, since a part of the liquid-absorbing filament yarn forming the knitted fabric is crimped, the amount of the transpiration component is increased compared to a knitted fabric having the same area and the same basis weight. Can be made. For this reason, although it is said that the volatilization effect of the transpiration component can be continued for a long period of time, the type of Patent Document 1 is preferable in terms of the sustained release performance of the transpiration component. It was the same as the case of 2.

In view of the growing need for scented products obtained by adding a fragrance component to the chemical volatilization body and the transpiration material of Patent Documents 1 to 3, the present inventors have previously made a patent (Patent Document 4: Japanese Patent Application No. 2013). 38085), and proposed a scented insect repellent in which a carrier containing a resin carries a pyrethroid insect repellent component having volatility at room temperature and a perfume component having a boiling point in the range of 250 to 400 ° C. This insect repellent can continue to volatilize the pyrethroid-based insect repellent component having volatility at room temperature for a long period of time, and further, the aromatic effect can be obtained by the period when the insect repellent effect is obtained by the pyrethroid-based insect repellent component and the perfume component. It was possible to link the obtained period and it was very useful. However, there are cases in which the inconvenience in production and the influence between the two components are caused by mixing insect repellent and perfume ingredients, leaving room for improvement.

JP 2009-7382 A JP 2012-236679 A International Publication No. 2010/058817 Japanese Patent Application No. 2013-38085

The present invention has been made in view of the above problems, and has an insecticidal effect over a long period of time by a room temperature volatile pyrethroid insect repellent component. It is an object of the present invention to provide a scented chemical volatilization body that can be interlocked and does not cause inconvenience in production and influence between the two components.

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

(8) The scented drug volatilizer according to any one of (1) to (7), wherein a recess for accommodating the carrier for the fragrance component is provided on the front surface of the container.

Since the fragrance | flavor component contained in the chemical | medical agent volatilization body with a fragrance which concerns on this invention has a boiling point in the range of 250-400 degreeC, and is a thing which is relatively hard to volatilize, a fragrance continues over a long term. By forming each support on a separate carrier, a pyrethroid-based insect repellent having volatility at room temperature (hereinafter simply referred to as “pyrethroid-based insect repellent”) and the fragrance component are formed over a long period of time. It becomes easy to exhibit an insect repellent effect, and to link the period of the insect repellent effect and the period in which the aroma effect is obtained by the fragrance component. Furthermore, it is extremely practical because it does not cause inconvenience in production and influence between the two components.

(A) The perspective view of the chemical volatilization body manufactured in the Example, (b) The front view of (a), cc sectional drawing of (c) (b)

Hereinafter, the scented chemical volatilization body of the present invention will be described. However, the present invention is not intended to be limited to the embodiments described below.

First, in this specification, the extermination effect and the repellent effect by a pyrethroid type insect repellent component will be referred to as “insect repellent effect”. In addition to the effect of killing larvae and adult insects such as flying insects (including clothing insects), this insect-repellent effect is a repellent effect that keeps the insects away, an effect to prevent invasion of dwellings and clothes, and an effect to prevent food damage such as clothes It means the overall effect of including the etc. Examples of the pest targeted by the present invention include mosquitoes, flyfish, chironomids, butterflies, moths, leafhoppers, and feather ants.

<Supporting component of scented chemical volatilizer>
In the scented chemical volatilization body of the present invention, (A) a room temperature volatile pyrethroid insect repellent component and (B) a perfume component having a boiling point in the range of 250 to 400 ° C. are supported on separate carriers. The body is formed. Hereinafter, each component will be described.

(A-1) Pyrethroid-based insect repellent component As the pyrethroid-based insect repellent component, one having volatility at room temperature is used. Here, “having volatility at normal temperature” means to show a vapor pressure of 0.001 Pa or more at 25 ° C., and volatilization at normal temperature if the volatilization amount is 0.005 mg / hr or more. It can be regarded as having. Examples of such pyrethroid insect repellent components include transfluthrin, metfurthrin, profluthrin, and empentrin. These pyrethroid insect repellent components can be used alone, but may be used in the form of a mixture of two or more. In addition, these pyrethroid insect repellent components include optical isomers and geometric isomers based on asymmetric carbons and double bonds, and these can be used alone or as an arbitrary mixture. By the way, the boiling point of the pyrethroid insect repellent component is about 300 to 400 ° C. under atmospheric pressure.

In the pyrethroid type insect repellent component carrier constituting the scented drug volatilizer of the present invention, the content of the insect repellent component varies depending on the type, use environment, use conditions, and the like, and thus is not particularly limited. However, in order to ensure the amount of components necessary for the insect-repellent effect, the pyrethroid insect repellent component carried on the carrier (the carrier will be described in detail later) is preferably in the range of 0.5 to 20% by mass. When the content of the pyrethroid-based insect repellent component is less than 0.5% by mass, it is difficult to obtain a sufficient insect repellent effect. On the other hand, if the content of the pyrethroid insect repellent component exceeds 20% by mass, the surface of the carrier becomes sticky due to the viscosity of the pyrethroid insect repellent component, making it difficult to use.

When using methfluthrin, profluthrin, and transfluthrin alone, the volatilization amount necessary for exerting the insect repellent effect is 0.03 mg / hr or more for metofluthrin and profluthrin, and 0.06 mg / hr or more for transfluthrin. It is. Therefore, if the period of use of the scented chemical volatilization body is 30 to 365 days, the content of the insect repellent component in the pyrethroid insect repellent component carrier is suitably 30 to 1000 mg for methfluthrin and profluthrin, and about 60 to 2000 mg for transfluthrin. It is. Therefore, what is necessary is just to set suitably the standard of content of a pyrethroid type insect repellent component in the range of about 30-2000 mg with respect to the use period of about 30-365 days.

(A-2) Method of supporting pyrethroid insect repellent component As a method of supporting a pyrethroid insect repellent component on a carrier, for example, a resin carrier is used, and (M-1) a resin carrier kneaded with a pyrethroid insect repellent component is extruded. Or a method of injection molding (including a method of preparing a master batch in which a pyrethroid insect repellent component is kneaded at a high concentration in the first stage and then diluting the master batch to a predetermined concentration with a resin carrier and performing extrusion molding or injection molding) (M -2) A method of impregnating a solution containing a pyrethroid-based insect repellent component with a net-shaped resin molding or a net-shaped knitted fabric composed of resin filaments, (M-3) a pyrethroid-based insect repellent component or a solution containing this , Sprayed, dripped or dispensed into a net-like knitted fabric composed of a net-like resin molding or resin filament, and pyrethroid insect repellent The method or the like to be attached to the surface or near the surface of the carrier. In performing the supporting step, for example, the insect repellent component is not directly supported on the resin carrier, but the insect repellent component is attached to inorganic fine particles such as microcrystalline silica, and the inorganic fine particles to which the insect repellent component is attached are supported on the resin carrier. It is also possible to mix them.
A suitable carrier is selected in accordance with these loading methods, and the carrier to be formed is preferably a net having an appropriate opening considering the volatilization performance of the insect repellent component.

(A-3) Auxiliary component for pyrethroid insect repellent component For the purpose of uniformly supporting the pyrethroid insect repellent component with a carrier or adjusting the volatility of the insect repellent component, in the present invention, 220 ~ One or more selected from paraffinic hydrocarbons having a boiling point in the range of 500 ° C., aliphatic carboxylic acid ester compounds having a total carbon number of 14 to 22 in the acid part and alcohol part, and glycol ether compounds Can be blended.
As described in “(A-2) Method for supporting pyrethroid-based insect repellent component” in paragraph [0017], in the method for supporting (M-1) and (M-2), a pyrethroid-based insect repellent component is encapsulated in a carrier, The volatility of the insect repellent component can be adjusted considerably depending on the type and composition of the carrier. Therefore, the blending of such auxiliary components is particularly useful when the (M-3) loading method in which the pyrethroid insect repellent component is attached to the surface of the carrier or in the vicinity of the surface is employed.

Paraffinic hydrocarbons are a type of hydrocarbon compound and are organic compounds contained in crude oil. Various paraffinic hydrocarbons are produced by purifying the paraffinic hydrocarbons by fractional distillation or the like, or adjusting the viscosity. In the scented chemical volatilization body of the present invention, a paraffinic hydrocarbon (liquid paraffin) prepared to have fluidity is employed in order to support the pyrethroid insect repellent component on a carrier, preferably a resin carrier. When the paraffinic hydrocarbon having the above boiling range is used, the pyrethroid insect repellent component can be uniformly dispersed in the carrier. Therefore, there is no variation in the volatilization state of the pyrethroid insect repellent component depending on the part of the carrier, and the pyrethroid insect repellent component can be volatilized substantially uniformly from the entire carrier. Moreover, the controllability of the volatilization state of the pyrethroid insect repellent component from the carrier is also good. As a result, the pyrethroid insect repellent component can be sufficiently and appropriately distributed in the processing space. In addition, it becomes easy to link the period in which the insect repellent effect is obtained by the pyrethroid-based insect repellent component and the period in which the aroma effect is obtained by the perfume component, and over the entire period in which the effect of the pyrethroid-based insect repellent component is exerted, Aroma can be imparted to the treatment space.

Here, when the boiling point of the paraffinic hydrocarbon is lower than 220 ° C., the paraffinic hydrocarbon is volatilized earlier than the pyrethroid insect repellent component. Equal volatilization during the period becomes difficult. On the other hand, when the boiling point of the paraffinic hydrocarbon is higher than 500 ° C., the viscosity of the paraffinic hydrocarbon is large, so that it is difficult to handle and it is difficult to carry the pyrethroid insect repellent component on the carrier.

Examples of the paraffinic hydrocarbon include liquid paraffin manufactured by Sanko Chemical Co., Ltd. (product numbers “40-S”, “55-S”, “60-S”, “70-S”, “80-S”). “S”, “90-S”, “100-S”, “120-S”, “150-S”, “No. 30”, “No. 60”, “No. 70”, “No. 80” , “No. 100”, “No. 350”, etc.) can be used.

In addition, a compound selected from an aliphatic carboxylic acid ester compound having a total number of carbon atoms in an acid portion and an alcohol portion of 14 to 22 and a glycol ether compound has the same effect as that of the paraffinic hydrocarbon. Here, examples of the aliphatic carboxylic acid ester compound having a total carbon number of 14 to 22 in the acid portion and the alcohol portion include isopropyl myristate, butyl myristate, hexyl myristate, ethyl laurate, butyl laurate, and laurin. Examples include, but are not limited to, hexyl acid and octyl laurate.

Furthermore, the glycol ether compounds include triethylene glycol monomethyl ether, diethylene glycol monobutyl ether, triethylene glycol monobutyl ether, diethylene glycol isobutyl ether, diethylene glycol monophenyl ether, diethylene glycol monobenzyl ether, tripropylene glycol monomethyl ether, tripropylene glycol monoethyl. Ether, tripropylene glycol monobutyl ether, propylene glycol monophenyl ether, diethylene glycol dibutyl ether and the like are preferably used.

(B-1) Fragrance ingredient
The scented chemical volatilization body of the present invention is characterized in that the fragrance component carrier is formed separately from the pyrethroid insecticide component carrier. Here, a fragrance | flavor component has a boiling point in the range of 250-400 degreeC, and is used in the state carry | supported by the support | carrier as mentioned later (a boiling point means the boiling point under atmospheric pressure).
When the boiling point of the fragrance component is lower than 250 ° C., the fragrance component carried on the carrier is easily volatilized, so that the fragrance effect by the fragrance component is difficult to last for a long time. In addition, since a large amount of the fragrance component is volatilized in the initial stage of use of the scented chemical volatilization body, so-called “scenting” may occur at a stretch, which may cause discomfort to the user.
On the other hand, since the fragrance | flavor component becomes difficult to volatilize when the boiling point of a fragrance | flavor component is higher than 400 degreeC, sufficient fragrance may not be provided with respect to processing space. If the boiling point of a fragrance | flavor component exists in the range of 250-400 degreeC, since it is excellent in the persistence of an aroma effect and will be in a state with a suitable fragrance, an ideal scented chemical volatilization body can be provided.

Examples of perfume ingredients having a boiling point in the range of 250 to 400 ° C. include galaxolide, musk ketone, hexyl cinnamic aldehyde, ethylene brushate, methyl atrate, hexyl salicylate, tricyclodecenyl acetate, orange crystal, ambroxan, and cash Melan, caron, heliotropin, indole aroma, indole, methyl cedryl ketone, methyl β-naphthyl ketone, methyl dihydrojasmonate, rosephenone, 7-acetyl-1,2,3,4,5,6,7, 8-octahydro-1,1,6,7-tetramethylnaphthalene, acetoacetic acid-m-xylidide, acetoacetic acid-o-toluidide, acetosyringone, acetyltriethyl citrate, benzophenone, benzylbenzoate, benzyl Prelate, benzyl cinnamate, benzyl eugenol, benzyl laurate, benzyl methyl tiglate, benzyl phenyl ether, benzyl phenyl acetate, benzyl salicylate, geranyl anthranilate, geranyl hexanoate, geranyl cyclopentanone, geranyl phenyl acetate , Hexylphenyl acetate, icosane, indane, cinnamyl butyrate, cinnamyl phenyl acetate, hexenyl benzoate, citral diethyl acetal, ionone, isoamyl benzoate, linalyl octanoate, 1-menthyl salicylate, citronellyl anthranilate, dimethyl Phenethyl carvinyl isobutyrate, diphenyl oxide, dodecyl butyrate, ethyl vanillate, ethyl vanillate , Menthyl isovalerate, methoxyethyl phenylglycidate, methyl 2,4-dihydroxy-3,6-dimethylbenzoate, nerolidyl acetate, neryl isovalerate, octenyl cyclopentanone, octyl caprylate, phenethyl isoamyl ether, phenethyl Octanoate, phenethyl phenylacetate, ethyl vanillin acetate, ethyl vanillin propylene glycol acetal, ethyl hexyl palmitate, eugenyl benzoate, farnesol, farnesyl acetate, farnesyl methyl ether, formaldehyde cyclododecyl methyl acetal, formylethyl tetramethyltetralin, furfuryl Benzoate, γ-dodecalactone, phenethyl salicylate, phenoxyethyl pro Onato, phenyl benzoate, phenyl disulfide, Santa Lil butyrate, tetrahydro - pseudo - ionone, theobromine, and valencene, and the like. Among these perfume ingredients, preferred are galaxolide, musk ketone, hexylcinnamic aldehyde, ethylene brushate, methyl atrate, hexyl salicylate, tricyclodecenyl acetate, orange crystal, ambroxan, cashomeran, caron, Heliotropin, indole aroma, indole, methyl cedryl ketone, methyl β-naphthyl ketone, methyl dihydrojasmonate, rosephenone, and 7-acetyl-1,2,3,4,5,6,7,8-octahydro -1,1,6,7-tetramethylnaphthalene. The above fragrance components can be used alone, but may be used as a mixture of two or more.

The above fragrance component has a boiling point in the range of 250 to 400 ° C. and can be volatilized over a long period of time, so that it has excellent fragrance effect sustainability. Therefore, it is possible to impart fragrance to the treatment space over the entire period during which the insect repellent effect of the pyrethroid insect repellent component is exhibited. That is, it is possible to link the period in which the insect repellent effect is obtained by the pyrethroid insect repellent ingredient and the period in which the aroma effect is obtained by the perfume ingredient. In this case, the perfume ingredient of the scented chemical volatilizer is It can be a display function of insect repellent effect. For example, when the fragrance of the fragrance component disappears or the fragrance of the fragrance component cannot be sensed, the user ends the use of the scented chemical volatilizer and replaces it with a new one as necessary. It can be recognized as a “notification sign”.

On the other hand, the fragrance has an effect of relaxing a person, and the same effect can be expected in the fragrance component contained in the insecticide carrier. Therefore, the scented chemical volatilization body of the present invention can give a user not only an insect-repellent effect but also a relaxing effect due to aroma.

By the way, said fragrance | flavor component has a flying insect repellent effect to some extent in addition to an aroma effect. Therefore, if the above fragrance ingredients are used, a stable and enhanced insect proof effect is exhibited from the initial stage of use to the final stage of use of the scented chemical volatilizer due to the synergistic effect of the pyrethroid insecticide ingredients and the fragrance ingredients. Is done.

Since the fragrance | flavor component content in the support body of a fragrance | flavor component changes with the kind, use environment, use conditions, etc., it does not specifically limit. However, in order to ensure the component amount necessary for imparting fragrance, the fragrance component carried on the carrier is preferably in the range of 2.0 to 30% by mass. When content of a fragrance | flavor component is less than 2.0 mass%, it becomes difficult to acquire sufficient aroma effect. On the other hand, when the content of the fragrance component exceeds 30% by mass, the surface of the carrier becomes sticky due to the viscosity of the fragrance component, making it difficult to use.

If content of a fragrance | flavor component is illustrated, it will be about 100-2200 mg with respect to the use period of about 30 days-365 days. If it is said range, while being able to exhibit the stable insect repellent effect by the synergistic effect with a pyrethroid type insect repellent component, the fragrance of a fragrance | flavor component can be provided to a processing space and a user can recognize use feeling. . Furthermore, the relaxation effect by fragrance can also be given to a user.

In addition to the above-mentioned fragrance components, it is also possible to add a somewhat high volatility flying insect repellent fragrance composition to the fragrance component-supporting body used in the present invention. Here, the flying pest repellent fragrance composition is (a) general formula (1) as a flying pest repellent fragrance.

Examples of the allyl ester compound represented by the general formula (2) include allyl hexanoate, allyl heptanoate, allyl octanoate, allyl isobutyloxy acetate, allyl n-amyloxy acetate, allyl cyclohexyl acetate, Examples include allyl cyclohexyl propionate, allyl cyclohexyl oxyacetate, and allyl phenoxy acetate.

Examples of the (b) monoterpene alcohol or aromatic alcohol having 10 carbon atoms include terpineol, geraniol, dihydromyrcenol, tetrahydromyrcenol, borneol, menthol, citronellol, nerol, linalool, ethyl linalool, And thymol, eugenol, and p-menthane-3,8-diol.

Furthermore, one or more of glycols and / or glycol ethers having a vapor pressure of 0.2 to 20 Pa at 20 ° C. can be blended as a repellent effect sustained component at the time of volatilization of the flying insect repellent component. The repellent effect continuous component can contribute not only to the flying pest repellent fragrance but also to the fragrance component to improve the sustained action.
Examples of the repellent effect continuous component include propylene glycol (10.7 Pa), dipropylene glycol (1.3 Pa), tripropylene glycol (0.67 Pa), diethylene glycol (3 Pa), triethylene glycol (1 Pa), 1 , 3-butylene glycol, hexylene glycol (6.7 Pa), benzyl glycol (2.7 Pa), diethylene glycol monobutyl ether (3 Pa), dipropylene glycol monobutyl ether, and tripropylene glycol monomethyl ether. Of these, dipropylene glycol is preferred. The value in parentheses described immediately after each component is the vapor pressure at 20 ° C. The blending ratio of glycol and / or glycol ether to the flying insect repellent is preferably about 0.2 to 10 times.

In addition, the fragrance component carrier used in the present invention, as a flying insect repellent fragrance, other fragrance components, for example, monoterpene hydrocarbons such as limonene, monoterpene series such as menthone, carvone, pregon, camphor, damascon, etc. Monoterpene aldehydes such as ketone, citral, citronellal, neral, and perilaldehyde, ester compounds such as cinnamyl formate and geranyl formate, and phenylethyl alcohol may be added. Furthermore, various essential oils containing the above fragrance ingredients, such as jasmine oil, neroli oil, peppermint oil, bergamot oil, orange oil, geranium oil, petitgren oil, lemon oil, citronella oil, lemongrass oil, cinnamon oil, eucalyptus Oil, lemon eucalyptus oil, and thyme oil may be added.

(B-2) Method for supporting a fragrance component As a method for supporting a fragrance component, for example, (N-1) a fragrance component is used in the same manner as in “(A-2) Method for supporting a pyrethroid insect repellent component” in paragraph [0017]. A method of extrusion molding or injection molding of a kneaded resin carrier (a method of preparing a master batch in which a fragrance component is kneaded at a high concentration in the first stage, and then diluting this to a predetermined concentration with a resin carrier to perform extrusion molding or injection molding (N-2) a method of impregnating, dropping or dispensing a perfume component or a solution containing it into a resin or fibrous material sheet that may have a large number of continuous or intermittent voids, N-3) A fragrance component or a solution containing the fragrance component may have a number of continuous or intermittent voids, for example, sprayed, dropped or dispensed onto a sheet-like fiber structure, and the fragrance component is The surface of the carrier or near the surface The method or the like for attaching the like.
And a support | carrier is selected corresponding to these loading methods, and the fragrance | flavor component support body used for this invention is produced. In the case of a pyrethroid-based insect repellent component carrier, a net-like shape is generally preferred, whereas the shape of the perfume component-supported body is higher in volatility of the perfume component than the usual pyrethroid-based insect repellent component, and an indication of the insect repellent effect In consideration of ease of use as a function, a sheet-like one is preferable.

(B-3) Auxiliary component for fragrance component “(A-3) Auxiliary component for pyrethroid-based insect repellent component” The purpose of uniformly supporting the fragrance component with a carrier or adjusting the volatility of the fragrance component In the present invention, one or two selected from paraffinic hydrocarbons having boiling points in the range of 220 to 500 ° C. and aliphatic carboxylic acid ester compounds having a total number of carbon atoms in the acid portion and the alcohol portion of 14 to 22. More than one species can be blended.
By allowing the fragrance component to coexist with the paraffinic hydrocarbon or the aliphatic carboxylic acid ester compound, the fragrance component does not decompose in the carrier and the stability of the fragrance component is improved. Therefore, the stability of the fragrance effect of the fragrance component is ensured, and the fragrance component can be volatilized over an ideal period to maintain the fragrance.
When the fragrance component and the paraffinic hydrocarbon or aliphatic carboxylic acid ester compound are selected such that the difference between the boiling point of the fragrance component and the boiling point of the paraffinic hydrocarbon or aliphatic carboxylic acid ester compound is 50 ° C. or less, While appropriately adjusting the volatilization amount of the fragrance component, it can be volatilized over a long period of time, and the fragrance continues for a desired period.

By the way, as described in paragraph [0035], the fragrance component preferably has a vapor pressure at 20 ° C. of 0.2 to 0.2 as a fragrance (repellent effect) sustaining component at the time of volatilization of the fragrance component (flying insect repellent component). One or more of 20 Pa glycol and / or glycol ether are blended. In this case, it can be said that the fragrance (repellent effect) sustaining component also serves as the auxiliary component for the fragrance component here. .
The effect of the auxiliary component is, as in the case of the auxiliary component for the pyrethroid insect repellent component, as the supporting method: “(N-3) Fragrance component or a solution containing the same is used in a number of continuous or intermittent voids. Is particularly useful when, for example, a method of spraying, dripping or dispensing to a sheet-like fiber structure and attaching a fragrance component to or near the surface of the carrier is adopted. .

(C) Other ingredients
Each said support body of the fragrant drug volatilization body of this invention can contain various additives other than said each component. For example, antifungal agents (2-phenylphenol (OPP), 4-isopropyl-3-methylphenol (IPMP), 2-n-octyl-4-isothiazolin-3-one, isopropylmethylphenol, etc.), antibacterial agents (hinokitiol) , Eugenol, allyl isothiocyanate, etc.), disinfecting components, stabilizers such as BHT, pH adjusters, colorants, UV absorption inhibitors (paraaminobenzoic acids, cinnamic acids, salicylic acids, benzophenones, benzotriazoles, etc.) In addition, various petroleum solvents and the like can be appropriately contained. Moreover, fragrance | flavors, such as green leaf alcohol and green leaf aldehyde called "green fragrance", can also be contained suitably.

<Carrier>
In using the scented chemical volatilization body, in order to give the user a sense of use, it is necessary that the fragrance component is supported on the carrier in a state where it is volatilized appropriately in the treatment space. In addition, the pyrethroid insect repellent component needs to be supported on a carrier so that the insect repellent effect is effectively exhibited. Therefore, in the present invention, as each carrier for supporting the pyrethroid insect repellent component and the fragrance component, a carrier that can easily adjust the volatilization amount according to the loading method is adopted.
For example, polyolefin resin such as polyethylene and polypropylene, or polyolefin copolymer formed by polymerizing monomers such as carboxylic acid ester, silicone rubber, silicone resin, styrene diblock polymer, styrene Although a triblock polymer etc. are mentioned, it is not limited to these. Further, the insecticidal component carrier and the perfume component carrier need not be the same material.

In the “kneading type”, as a resin carrier for supporting a pyrethroid insect repellent component, a polyolefin resin such as polyethylene or polypropylene, or a polyolefin copolymer formed by polymerizing a monomer such as a carboxylic acid ester with these resins. Polymers are common. Here, examples of the monomer such as carboxylic acid ester include methyl acrylate, ethyl acrylate, methyl methacrylate, ethyl methacrylate, and vinyl acetate. The resin carrier may be a polymer blend in which a polyolefin copolymer containing a large amount of a carboxylic acid ester monomer and an olefin homopolymer are mixed in advance by adjusting the content ratio. Moreover, you may make the prepared resin support | carrier contain other high molecular compounds, such as a styrene-type thermoplastic elastomer.

On the other hand, in the case of “(M-2) impregnation type” or “(M-3) surface adhesion type”, as a carrier, preferably a resin carrier, for example, polyethylene, polypropylene, polyamide, polyethylene terephthalate (PET), polybutylene terephthalate. (PBT), polysulfone, rayon, polyvinyl alcohol, polyacrylonitrile, polyurethane and the like can be mentioned, and they are appropriately selected according to the purpose.
In particular, in “(M-3) surface adhesion type”, a resin carrier such as PET or PBT, which is usually non-adsorbable with respect to the pyrethroid insect repellent component, is preferably used, from a monofilament or a multifilament (twisted yarn). It is formed into a structured net-like knitted fabric.
In addition, as a method of adjusting the volatility of the pyrethroid insect repellent component, crimping processing is performed on PET, PBT, etc., or a resin fiber structure is formed by combining long fibers and short fibers, and a resin such as PET, PBT is used. A method of modifying a resin carrier by blending the above-mentioned polyolefin resin, styrene thermoplastic elastomer, and rayon can also be adopted.

The volatilization amount of the pyrethroid insect repellent component from the resin carrier varies depending on the type of resin constituting the carrier, but can be adjusted, for example, by changing the surface area of the carrier. For example, when the resin carrier is configured as a porous body or a three-dimensional structure, the surface area of the resin is increased, so that the volatility of the pyrethroid insect repellent component is improved. Therefore, if a suitable resin is selected as a carrier and the surface area of the carrier is appropriately adjusted, a scented drug volatilization body in which the volatilization amount of the pyrethroid insecticide component is highly controlled can be realized. In order to make the carrier porous, for example, a method in which the carrier is made of a two-component polymer blend and one resin is eluted with a solvent to form a porous structure, or the carrier is made of a foamable resin. And a method of forming a porous structure from the surface to the inside by foaming the resin.

(D-2) Resin carrier for carrier of perfume component As with the resin carrier for carrier of pyrethroid insect repellent component, the preferred carrier varies depending on the loading method. In the scented chemical volatilization body of the present invention, a fragrance component having a boiling point in the range of 250 to 400 ° C. is used. However, it is somewhat more volatile than a pyrethroid insect repellent component and tends to be easily altered by heat. Therefore, it is preferable not to apply a heating step.
However, if it is low temperature of 100 degrees C or less, it can respond according to "(N-1) kneading type" of "(B-2) Method for carrying insect repellent" in paragraph [0037], and pyrethroid insect repellent As in the case of the component “(M-1) kneading type”, a polyolefin resin such as polyethylene and polypropylene, or a polyolefin copolymer formed by polymerizing a monomer such as a carboxylic acid ester to the resin is suitable. As a suitable resin carrier. However, it is preferable that the ratio of the monomer such as a carboxylic acid ester in the polyolefin copolymer is usually adjusted to be higher than that of the resin carrier for the support of the pyrethroid insect repellent component.

In “(N-2) impregnation, dispensing type”, properties that are easy to absorb the perfume component and are moderately easy to release are required, and a resin material or a carrier of various fibrous materials is preferably used. . Examples of the resin material include polyethylene, ethylene vinyl acetate copolymer, silicone rubber or silicone resin having a hardness of 40 to 90 degrees, styrene diblock polymer, styrene triblock polymer, and the like. Examples of the material include pulp, linter, cellulose, rayon, paper, and the like. In particular, when the fragrance component carrier is formed on a resin sheet, an ethylene vinyl acetate copolymer or a silicone resin is suitable as a material, and the resin sheet is provided with a large number of continuous or intermittent voids. Also good.

In “(N-3) surface adhesion type”, as in the case of the pyrethroid insect repellent component, PET or PBT that is non-adsorbable to the fragrance component, or a fiber structure in which polyethylene or rayon is blended with these. Is preferably used and should be designed so that the attached fragrance component is easily retained. In addition, as in the case of the pyrethroid insect repellent component, a paraffinic hydrocarbon having a boiling point in the range of 220 to 500 ° C. and an aliphatic carboxylic acid ester compound having a total number of carbon atoms in the acid portion and the alcohol portion of 14 to 22 are used in combination. By doing so, it becomes possible to control the volatilization state of the fragrance component to some extent.

When the fragrance component is supported on the carrier, it is also effective to change the loading method according to the type of the fragrance component and the use environment. For example, when a perfume component having a relatively low boiling point of about 250 to 300 ° C. is used, the perfume component tends to volatilize earlier than the pyrethroid insect repellent component. Is made. For example, the carrier of the room temperature volatile pyrethroid insect repellent component is housed in a container having openings at least on the front and the back, while the carrier of the fragrance component is housed in a recess on the front of the non-breathable container. The volatilization of components can also be suppressed. On the other hand, when using a perfume component having a relatively high boiling point of about 350 to 400 ° C., the perfume component is less likely to volatilize than the pyrethroid insect repellent component, and thus the above installation method is not effective.

Thus, by changing the loading method on the carrier according to the difference in boiling points of the pyrethroid insect repellent component and the perfume component, it is possible to produce a scented chemical volatilizer excellent in balance between the insect repellent effect and the aroma effect. It can respond to various pests and usage environments. In addition, when changing the loading method on the carrier depending on the kind of pyrethroid insect repellent component and perfume component, the paraffin hydrocarbon to be used and the aliphatic carboxylic acid ester compound having a total number of carbon atoms of 14 to 22 are appropriately selected. It is preferable to do. By using an optimal paraffinic hydrocarbon, an aliphatic carboxylic acid ester compound, etc., the insect repellent effect and the aroma effect can be effectively exhibited over the planned use period.

<Scented chemical volatilizer>
The scented chemical volatilization body of the present invention is used in a state where a carrier of a pyrethroid insect repellent component is housed in an appropriate container and a carrier of a fragrance component is loaded in the container. The shape and size of the suitable container are not particularly limited, but since the volatilization of the pyrethroid insect repellent component and the fragrance component needs to be sustained for a long period of time, the container has openings at least on the front surface and the back surface and has air permeability. It must be good. In addition, the term “loading” as used herein refers to storage of a fragrance component carrier inside a container, engagement to the inner surface and outer surface of the container, accommodation in a recess provided on the surface of the container, and further, a fragrance component carrier. It includes all aspects such as attachment of what is wrapped in a perforated film.
The breathable container is produced, for example, by thermoforming a thermoplastic resin. When performing thermoforming, the breathable container can be molded as a single piece, but it is also possible to mold a plurality of parts in advance and combine them into a breathable container. A hook for hanging on a hanger pipe or the like of a closet can be formed in the breathable container at the same time. Examples of the molding method of the breathable container include hot plate pressure molding, injection molding, blow molding molding, insert molding and the like. The thermoplastic resin used for molding is polyester (PET), polyethylene (PE), polypropylene (PP), polyamide (PA), polylactic acid (PL), polystyrene (PS), polyvinyl chloride (PVC), polyacetic acid. Examples include vinyl (PVAc) and polycarbonate (PC).

The scented chemical volatilization body of the present invention is, as described above, loaded with a fragrance ingredient carrier in the container, and linked the insect repellent effect of the pyrethroid insect repellent ingredient and the aroma effect of the fragrance ingredient. Therefore, the loading method of the fragrance component carrier is determined in consideration of the volatility of the pyrethroid insect repellent component as well as the fragrance component, the air permeability of the housing portion of the fragrance component carrier, and the like.
For example, when using a relatively highly volatile fragrance component having a boiling point in the range of 250 to 300 ° C. and making a support by impregnation using a silicone resin as a carrier, it seems to be linked to the volatilization performance of the pyrethroid insect repellent component. In addition, it is appropriate to adopt a method in which a silicone resin carrier is accommodated in a recess provided in front of the container, and the back surface of the recess is impermeable.
On the other hand, when using a relatively low volatility fragrance component having a boiling point in the range of 350 to 400 ° C., a sheet-like knitted fabric is prepared using a multifilament obtained by twisting a plurality of polyester fibers, and the fragrance component is formed on the surface. It is cerebral that adopts the method of adhering by dispensing. In this case, it is preferable that the rear surface of the concave portion that houses the fragrance component carrier is not air-impermeable.
That is, in determining the loading method of the fragrance component carrier, comprehensively examined the boiling point of the fragrance component, the volatilization performance of the pyrethroid insect repellent component, the type and physical properties of the carrier and the shape (porosity), the loading method, etc. This is possible only after conducting various tests.

The scented chemical volatilized product produced by the present invention is used for a predetermined period according to its design specifications from immediately after use until about 365 days, in a living room, a Japanese room, a front door, etc., a warehouse, a restaurant, a factory or a workplace, Its entrances, livestock houses such as poultry houses and pig houses, pet sheds such as kennels and rabbit huts and the surrounding area, inside septic tanks and manholes, inside tents and entrances to camping, barbecue, fishing, gardening, etc. Excellent insecticidal effect against mosquitoes such as mosquitoes, chikaeka, and mosquitoes in the surroundings, buoys, chironomids, flies, butterflies, moths, leafhoppers and feather ants. In addition, it is possible to effectively prevent the entry of these pests from the outside to the inside if the hook part is hooked on a curtain rail or the like, or is hung on a clothes rack in a place such as a window or a veranda that separates the room from the outside. You can also.
Furthermore, the chemical volatilization body can be formed in a cylindrical shape for attaching a lead for a pet dog, or the container can be appropriately simplified and used for attaching an air purifier or the like.
And the chemical | medical agent volatilization body with a fragrance of this invention links the period of the insect-proof effect and the period when an aroma effect is acquired with a fragrance | flavor component, and is very practical.
