Description

  The present invention relates to an insect repellent for controlling and repelling pests, an insect repellent containing the insect repellent in a container, and a method for producing the insect repellent.

  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, but in recent years, pyrethroid insecticides that have volatility at room temperature such as empentrin and profluthrin have been widely used. Yes. Insect repellents using these room temperature volatile components give off a unique odor, and may be avoided from consumers depending on the usage environment. Therefore, insect repellents with little odor have been developed and put into practical use. However, in recent years, consumer needs have been diversified, and a lot of aromatic products have been developed. 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, a transpiration material for controlling pests containing a transpiration component composed of an insecticide, a repellent or the like is known (for example, see Patent Document 1). The transpiration | evaporation material of patent document 1 uses a short fiber and a long fiber as a volatile body holding a transpiration component, and has provided the vent hole in the said volatile body. The volatilized body having such a configuration is said to have a higher amount of transpiration component and to be able to stably volatilize the volatile component over a long period of time.

  In addition, a transpiration material for controlling pests by holding a transpiration component as described above in a knitted fabric formed of liquid-absorbing filament yarn is also known (see, for example, Patent Document 2). In the transpiration material of Patent Document 2, 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, it is supposed that the volatilization effect of a transpiration component can be continued over a long period of time.

JP 2012-236679 A International Publication No. 2010/058817

  The transpiration material of Patent Document 1 is intended to stably evaporate the transpiration component over a long period of time while increasing the amount of the transpiration component retained. However, since the volatile component is used as a carrier, the transpiration component is used. It is difficult to control the volatilization state of this, and it is considered difficult to continue volatilizing the active ingredient over a long period of time as planned.

  On the other hand, the transpiration material of Patent Document 2 is devised to crimp a part of the knitted fabric, but since the base material of the transpiration material is composed of fibers as in Patent Document 1, the Patent Document 2 There is a problem similar to 1.

  The present invention has been made in view of the above problems, and can continuously volatilize a pyrethroid insecticide component having volatility at room temperature over a long period of time. Further, the pyrethroid insecticide component has an insecticidal effect.

  The scented insect repellent according to the present invention preferably contains a glycol ether compound.

In the scented insect repellent according to the present invention,
The pyrethroid insect repellent component is preferably at least one selected from the group consisting of transfluthrin, metfurthrin, profluthrin, and empentrin.

In the scented insect repellent according to the present invention,
The carrier containing the resin is preferably composed of a net-like knitted fabric.

In addition, the characteristic configuration of the scented insect repellent according to the present invention for solving the above problems is as follows:
One of the above scented insect repellents is contained in a container having air permeability.

Moreover, the characteristic structure of the manufacturing method of the scented insect repellent which concerns on this invention for solving the said subject is,
A method for producing a scented insect repellent comprising a supporting step of supporting a pyrethroid-based insect repellent component having volatility at room temperature and a perfume component having a boiling point in the range of 250 to 400 ° C on a carrier containing a resin ,
The perfume ingredients are galaxolide, musk ketone, hexyl cinnamic aldehyde, ethylene brushate, methyl atrate, hexyl salicylate, tricyclodecenyl acetate, oranger crystal, ambroxan, cachemelan, 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 It is at least one selected from the group consisting of 7-tetramethylnaphthalene, α-ionone, β-ionone, diphenyl oxide, damasenone, phenylacetic acid, damascon α, damascon β, and damascon δ .

In the method for producing a scented insect repellent according to the present invention,
In the supporting step, it is preferable to use paraffinic hydrocarbon having a boiling point in the range of 220 to 500 ° C.

In the method for producing a scented insect repellent according to the present invention,
In the supporting step, it is preferable to use an aliphatic carboxylic acid ester compound having a total of 12 to 20 carbon atoms in the acid portion and alcohol portion.

In the method for producing a scented insect repellent according to the present invention,
In the supporting step, it is preferable to use a glycol ether compound.

Since the fragrance | flavor component contained in the insect repellent 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 hard to volatilize relatively, a fragrance continues over a long period of time. Combining the above fragrance component with a pyrethroid insect repellent component that has volatility at room temperature (hereinafter simply referred to as “pyrethroid insect repellent component”), volatilizes the perfume component over the entire duration of the pyrethroid insect repellent component. It becomes possible to continue doing. Therefore, it is possible to link the period in which the insect repellent effect is obtained by the pyrethroid insect repellent component and the period in which the aroma effect is obtained by the perfume ingredient.
In addition, the scented insect repellent according to the present invention includes a paraffinic hydrocarbon having a boiling point in the range of 220 to 500 ° C., an aliphatic group having a total of 12 to 20 carbon atoms in the acid portion and alcohol portion. Since the carboxylic acid ester compound and / or the glycol ether compound are contained, the pyrethroid insect repellent component and the perfume component can be evenly dispersed when the pyrethroid insect repellent component and the perfume component are supported on the carrier. Therefore, there is no variation in the volatilization state of the pyrethroid insect repellent component and the fragrance component depending on the part of the carrier, and the pyrethroid insect repellent component and the fragrance component can be substantially volatilized from the entire carrier. Moreover, the controllability of the volatilization state of the pyrethroid insect repellent component and the fragrance component from the carrier is also good. As a result, it is possible to distribute the pyrethroid insect repellent component and the fragrance component sufficiently and appropriately in the treatment space. If a net-like knitted fabric is used as the carrier, the volatilized state of the pyrethroid insect repellent component and the fragrance component can be improved. Here, when a paraffinic hydrocarbon having a boiling point in the range of 220 to 500 ° C. is included, the difference between the boiling point of the fragrance component and the boiling point of the paraffinic hydrocarbon is 50 ° C. or less. It can be volatilized over a long period of time while adjusting to a fragrance for a desired period of time. Moreover, by coexisting a fragrance | flavor component and paraffin type hydrocarbon, the aliphatic carboxylic acid ester compound and / or glycol ether type compound whose sum total of carbon number of an acid part and carbon number of an alcohol part is 12-20. Even if the fragrance component is supported on a carrier, component decomposition or the like does not occur, 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.
Furthermore, since the period in which the insect repellent effect is obtained by the pyrethroid insect repellent component and the period in which the aroma effect is obtained by the perfume component are linked as described above, the user can use the perfume component simultaneously with the start of use of the scented repellent The sense of use of the scented insect repellent can be obtained. And if the user can no longer sense the fragrance, it can be easily recognized that the scented insect repellent is nearing the end of its life, so it can be used as a guide to end the use of the insect repellent or replace it with a new product. .
On the other hand, fragrance generally has an effect of relaxing a person, and the same effect can be expected in the fragrance component constituting the scented insect repellent of the present invention. Therefore, it is possible to give the user a relaxing effect due to the fragrance while being an insect repellent.
The scented insect repellent according to the present invention and the method for producing the scented insect repellent also have the same excellent effects as described above.

  Hereinafter, the manufacturing method of the scented insect repellent of the present invention, the scented insect repellent, and the scented insect repellent 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, stink bugs, and feather ants.

<Scented insect repellent>
The scented insect repellent of the present invention comprises (A) a pyrethroid insect repellent component having volatility at normal temperature and (B) a perfume component having a boiling point in the range of 250 to 400 ° C. supported on a resin-containing carrier. Is done. In addition to the components (A) and (B) above, the scented insect repellent of the present invention includes (C1) a paraffinic hydrocarbon having a boiling point in the range of 220 to 500 ° C., and (C2) carbon in the acid portion. An aliphatic carboxylic acid ester compound having a total of 12 to 20 carbon atoms and the number of carbon atoms in the alcohol moiety, and / or (C3) glycol ether compound can also be included. Hereinafter, each component will be described.

(A) 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.

  The content of the pyrethroid insect repellent component in the scented insect repellent of the present invention varies depending on the type of pyrethroid insect repellent component used, the use environment, the use conditions, and the like, and 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, when the period of use of the scented insect repellent is 30 to 250 days, the content of the pyrethroid insect repellent component in the scented insect repellent is 30 to 800 mg for metfurthrin and profluthrin, and 60 to 1600 mg for transfluthrin. . Therefore, the standard of the content of the pyrethroid insect repellent component is about 30 to 1600 mg for a use period of about 30 to 250 days.

(B) Fragrance | flavor component What has a boiling point in the range of 250-400 degreeC is used for a fragrance | flavor component. Boiling point means the boiling point under atmospheric pressure. As will be described later, the fragrance component is used in a state of being supported on a carrier containing a resin. 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 at the initial stage of use of the scented insect repellent, so-called “scenting” may occur at a stretch, which may cause discomfort to the user. When the boiling point of the fragrance component is higher than 400 ° C., the fragrance component is difficult to evaporate, and thus there is a possibility that sufficient fragrance cannot be imparted to the 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 a fragrance | flavor effect and a fragrance will be in an appropriate state, it can be set as an ideal scented insect repellent.

  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 Hexyl phenyl acetate, icosane, indane, cinnamyl butyrate, cinnamyl phenyl acetate, hexenyl benzoate, citral diethyl acetal, isoamyl benzoate, linalyl octanoate, 1-menthyl salicylate, citronellyl anthranilate, dimethylphenethylcar Vinyl isobutyrate, diphenyl oxide, dodecyl butyrate, ethyl vanillate, ethyl vanillin, menthyl Isovalerate, methoxyethyl phenylglycidate, methyl 2,4-dihydroxy-3,6-dimethylbenzoate, nerolidyl acetate, neryl isovalerate, octenylcyclopentanone, octyl caprylate, phenethyl isoamyl ether, phenethyl octanoate, Phenethyl phenyl acetate, ethyl vanillin acetate, ethyl vanillin propylene glycol acetal, ethyl hexyl palmitate, eugenyl benzoate, farnesol, farnesyl acetate, farnesyl methyl ether, formaldehyde cyclododecyl methyl acetal, formylethyl tetramethyl tetralin, furfuryl benzoate, γ- Dodecalactone, phenethyl salicylate, phenoxyethyl propionate Phenyl benzoate, phenyl disulfide, Santa Lil butyrate, tetrahydro - pseudo - ionone, theobromine, valencene, alpha-ionone, beta-ionone, damascenone, phenyl acetic acid, damascone alpha, damascone beta, and damascone δ 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, 7-acetyl-1,2,3,4,5,6,7,8-octahydro- 1,1,6,7-tetramethylnaphthalene, diphenyl oxide, α-ionone, β-ionone, damasenone, phenylacetic acid, damascon α, damascon β, and damascon δ. 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. For example, it is possible to link a period in which the insect repellent effect is obtained by the pyrethroid insect repellent component and a period in which the aroma effect is obtained by the perfume ingredient. In this case, the fragrance | flavor component of a scented insecticide can become a display function of an insecticidal effect with respect to a user. For example, when the fragrance of the fragrance component disappears or when the fragrance of the fragrance component can no longer be sensed, the user can stop using the scented insect repellent and replace it with a new one as necessary. it can.

  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 scented insect repellent of the present invention. Therefore, the scented insect repellent of the present invention can give a user not only an insect repellent effect but also a relaxing effect by aroma.

  Among the above-mentioned fragrance components, rose phenone, damasenone, phenylacetic acid, damascon α, damascon β, and damascon δ are fragrance components having a rose fragrance, and have a pleasant fragrance for the user. Therefore, when these fragrance ingredients are used in the scented insect repellent of the present invention, the scent of roses spreads in the treatment space, allowing the user to feel the insect repellent effect and giving the user a more relaxing effect. It becomes.

  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, the synergistic effect of the pyrethroid insect repellent ingredients and the fragrance ingredients provides a stable and enhanced insect repellent effect from the initial use stage to the end use stage of the scented insect repellent. The

  The content of the fragrance component in the scented insect repellent of the present invention varies depending on the type of the fragrance component to be used, the use environment, the use conditions, and the like, and is not particularly limited. 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 the fragrance | flavor component in a scented insect repellent is illustrated, it will be about 100-2000 mg with respect to a use period of about 30 days-about 250 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 a fragrance can be given to a user.

The scented insect repellent of the present invention can also be blended with a somewhat volatile flying insect repellent fragrance composition. Here, the flying pest repellent fragrance composition is (a) general formula (1) as a flying pest repellent fragrance.
CH ₃ —COO—R ₁ (1)
(Wherein R ₁ represents an alcohol residue having 6 to 12 carbon atoms); and / or General Formula (2)
R ₂ —CH ₂ —COO—CH ₂ —CH═CH ₂ (2)
(In the formula, R ₂ represents an alkyl group having 4 to 7 carbon atoms, an alkoxy group, a cycloalkyl group, a cycloalkoxy group, or a phenoxy group.) The above perfume ingredients,
(B) 1 type, or 2 or more types of fragrance | flavor components chosen from monoterpene-type alcohol or C10 aromatic alcohol are contained.
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 after 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 acetate ester compound represented by the general formula (1) include p-tert-butylcyclohexyl acetate, o-tert-butylcyclohexyl acetate, p-tert-pentylcyclohexyl acetate, benzyl acetate, phenylethyl acetate, Stylyl acetate, anisyl acetate, cinnamyl acetate, terpinyl acetate, dihydroterpinyl acetate, linalyl acetate, ethyl linalyl acetate, citronellyl acetate, geranyl acetate, neryl acetate, bornyl acetate, isobornyl acetate, etc. Is mentioned.

  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.

  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 scented insect repellent of the present invention has a perfume component other than the above as a flying insect repellent, for example, monoterpene hydrocarbons such as limonene, monoterpene ketones such as menthone, carvone, pregon and camphor, citral Monoterpene aldehydes such as 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, thyme oil, etc. may be added.

(C1) Paraffinic hydrocarbon In carrying the pyrethroid insecticidal component and the perfume component on the carrier, it is preferable to use a paraffinic hydrocarbon having a boiling point in the range of 220 to 500 ° C in the present invention. 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 insect repellent of the present invention, a paraffinic hydrocarbon (liquid paraffin) prepared so as to have fluidity is employed to support the pyrethroid insect repellent component and the perfume component on the carrier. When the paraffinic hydrocarbon having the above boiling range is used, the pyrethroid insect repellent component and the perfume component can be uniformly dispersed in the carrier. Therefore, there is no variation in the volatilization state of the pyrethroid insect repellent component and the fragrance component depending on the part of the carrier, and the pyrethroid insect repellent component and the fragrance component can be substantially volatilized from the entire carrier. Moreover, the controllability of the volatilization state of the pyrethroid insect repellent component and the fragrance component from the carrier is also good. As a result, the pyrethroid insect repellent component and the fragrance component can be sufficiently and appropriately distributed in the treatment 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. Further, by allowing the fragrance component and the paraffinic hydrocarbon to coexist, the fragrance component is not decomposed even if it is supported on 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. Here, when the boiling point of the paraffinic hydrocarbon is lower than 220 ° C., the paraffinic hydrocarbon is volatilized before the pyrethroid-based insect repellent component and the fragrance component, so that the dispersion state of the pyrethroid-based insect repellent component and the fragrance component in the carrier This causes a bias and makes it difficult to evenly volatilize during the period of use. 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-based insect repellent component and the fragrance component on the carrier. Furthermore, when the fragrance component and the paraffinic hydrocarbon are selected so that the difference between the boiling point of the fragrance component and the boiling point of the paraffinic hydrocarbon is 50 ° C. or less, the volatilization amount of the fragrance component is appropriately adjusted over a long period of time. It can be volatilized over and the fragrance will last for the desired period. When the fragrance | flavor component and paraffinic hydrocarbon in which the difference of the boiling point of a fragrance | flavor component and the boiling point of paraffin hydrocarbon exceeds 50 degreeC are selected, there exists a tendency for adjustment of the volatilization amount of a fragrance | flavor component to become difficult.

  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.

(C2) Aliphatic carboxylic acid ester compound in which the sum of the carbon number of the acid portion and the carbon number of the alcohol portion is 12 to 20, when the pyrethroid-based insect repellent component and the perfume component are supported on the carrier, It is preferable to use together an aliphatic carboxylic acid ester compound having a total of 12 to 20 carbon atoms and the carbon number of the alcohol moiety. The effect of the aliphatic carboxylic acid ester compound in which the total of the carbon number of the acid portion and the carbon number of the alcohol portion is 12 to 20 is the same as that of the paraffinic hydrocarbon.

  Examples of the aliphatic carboxylic acid ester compound having a total of 12 to 20 carbon atoms in the acid portion and alcohol portion include isopropyl myristate, butyl myristate, hexyl myristate, ethyl laurate, and butyl laurate. Hexyl laurate, octyl laurate and the like. These aliphatic carboxylic acid ester compounds may be used alone or in combination of two or more.

(C3) Glycol ether compound In order to carry a pyrethroid insect repellent component and a fragrance component on a carrier, in the present invention, it is preferable to use a glycol ether compound in combination. The efficacy of the glycol ether compound is the same as that of the paraffinic hydrocarbon. The glycol ether-based compound may be used in combination with various glycol ethers added as the above-described repellent effect sustaining component.

  Examples of 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, and tripropylene glycol monobutyl ether. , Propylene glycol monophenyl ether, and diethylene glycol dibutyl ether. These glycol ether compounds may be used alone or in combination of two or more.

[Carrier containing resin]
In using an insect repellent, in order to give a user a sense of use, it is necessary that the fragrance component is supported on the carrier in a state where the fragrance component is appropriately volatilized 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, a carrier containing a resin that easily adjusts the volatilization amount is employed as a carrier for supporting the pyrethroid insect repellent component and the fragrance component. The resin used for the carrier may be, for example, a polyolefin resin such as polyethylene or polypropylene, or a polyolefin copolymer formed by polymerizing a monomer such as a carboxylic acid ester. Here, examples of the monomer such as carboxylic acid ester include methyl acrylate, ethyl acrylate, methyl methacrylate, ethyl methacrylate, and vinyl acetate. The carrier containing the resin 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 adjusted in advance and mixed. Moreover, you may make the support | carrier containing the prepared resin contain other high molecular compounds, such as a styrene-type thermoplastic elastomer. Supporting the pyrethroid insect repellent component and the fragrance component on the resin-containing carrier is, for example, a method of extruding or injection molding a resin kneaded with the pyrethroid insect repellent component and the fragrance component, and kneading the pyrethroid insect repellent component or the fragrance component, respectively. A method of forming a carrier from a master batch, a method of dissolving a pyrethroid-based insect repellent component and a fragrance component in a solvent together with a resin, and drying and molding the obtained solution, a pyrethroid-based insect repellent component and a fragrance component by impregnation and spraying For example, a method of adhering to the surface of the carrier or the vicinity of the surface may be used. In addition, when the pyrethroid insect repellent component and the fragrance component are attached to the surface of the carrier or in the vicinity of the surface, the pyrethroid insect repellent component and the fragrance component tend to volatilize more easily than those kneaded inside the carrier. By using the hydrocarbons together, the volatilization state of the pyrethroid insect repellent component and the fragrance component can be controlled to some extent.

  The volatilization amount of the pyrethroid insect repellent component and the fragrance component from the carrier containing the resin varies depending on the type of the resin constituting the carrier, but can be adjusted, for example, by changing the surface area of the carrier. For example, if the carrier containing the resin is configured as a porous body, the surface area of the resin increases, so that the volatility of the pyrethroid insect repellent component and the fragrance component is improved. Therefore, if an appropriate resin is selected as the carrier and the surface area of the carrier is appropriately adjusted, a scented insect repellent in which the volatilization amount of the pyrethroid insect repellent component and the perfume 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.

  It is also possible to use a resin fiber structure as a carrier containing a resin. The scented insect repellent of the present invention uses a fragrance component having a boiling point in the range of 250 to 400 ° C. When paraffinic hydrocarbons are used in combination, it is possible to appropriately maintain the volatilization of the fragrance component. It becomes. Therefore, even if the carrier is a resin fiber structure, the fragrance component adheres to the resin fiber structure, the volatilization of the fragrance component can be sustained to some extent, and a fragrance can be imparted to the treatment space. For example, if a net-like knitted fabric is used as the resin fiber structure, the volatilized state of the pyrethroid insect repellent component and the fragrance component can be improved.

  Examples of the carrier containing a resin include polyethylene, polypropylene, polyamide, polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polysulfone, rayon, polyvinyl alcohol, polyacrylonitrile, and polyurethane. PET, PBT, and the like that are non-adsorbable with respect to the components are preferably used. In addition, as a method for adjusting the volatility of the pyrethroid insect repellent component and the fragrance component, crimp processing is applied to PET, PBT, etc., long fibers and short fibers are combined, and the above polyolefin-based resins are added to resins such as PET, PBT, etc. There is a method of modifying a resin carrier by blending a resin, a resin such as a styrene thermoplastic elastomer, and rayon.

  When loading the pyrethroid insect repellent component and the fragrance component on the carrier, it is also effective to change the loading method of each component according to the type and usage environment of the pyrethroid insect repellent component and the fragrance component. For example, when using a fragrance component having a relatively low boiling point of about 250 to 300 ° C., the fragrance component is likely to be volatilized earlier than the pyrethroid insect repellent component, so the scented insect repellent can be prepared by using a different loading method. Make it. For example, a perfume component is first kneaded into a carrier to form a resin porous body, and then a scented insect repellent is produced by a two-step process in which a pyrethroid insect repellent component is attached to the pores of the resin porous body. . By producing in this way, even when a fragrance component having a relatively low boiling point is used, the period in which the insect repellent effect is obtained by the pyrethroid insect repellent component and the period in which the fragrance effect is obtained by the fragrance component are linked. be able to. On the other hand, when a fragrance component having a relatively high boiling point of about 350 to 400 ° C. is used, the fragrance component is less volatile than the pyrethroid insect repellent component. Therefore, in this case, a pyrethroid insect repellent component is first kneaded into a carrier to form a resin porous body, and then a fragrance component is attached to the pores of the resin porous body.

  Thus, according to the difference in boiling point of the pyrethroid insect repellent component and the perfume component, by changing the loading method on the carrier, it is possible to produce a scented repellent excellent in balance between the insect repellent effect and the aroma effect, It can cope with various pests and usage environments. In addition, when changing the carrying | support method to a support | carrier with the kind of pyrethroid type insect repellent component and a fragrance | flavor component, it is preferable to select suitably also about the paraffin type hydrocarbon to be used. By using the optimum paraffinic hydrocarbon, the insect-proofing effect and the fragrance effect can be effectively exhibited over the planned use period.

The scented insect repellent of this invention is used in the state accommodated in the suitable container. As a container for containing a scented insect repellent, the shape and size are not particularly limited, but it is necessary to maintain the volatilization of the pyrethroid insect repellent component and the fragrance component over a long period of time. Is preferred. In this case, the scented insect repellent is accommodated in a breathable container as it is or in a state of being enclosed in a breathable bag. A plurality of ventilation holes through which pyrethroid insect repellent components and perfume components can pass are formed in the breathable container. 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, mold 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).

  As described above, the scented insect repellent of the present invention is a combination of the insect repellent effect of the pyrethroid insect repellent component and the fragrance effect of the perfume component. Therefore, if the user cannot sense the aroma, the pyrethroid It can be recognized that the insect repellent effect of the insect repellent component has also disappeared. Therefore, configure the scented insect repellent so that it can be removed from the container so that the used scented insect repellent can be removed from the breathable container and replaced with a new scented insect repellent when the fragrance effect is lost. Is also possible.

<Method for producing scented insect repellent>
The manufacturing method of the scented insect repellent of this invention is demonstrated. First, depending on the target flying pests and the environment of use, etc., the above pyrethroid insect repellent component, the perfume component having a boiling point in the range of 250 to 400 ° C., and other active ingredients as appropriate are appropriately blended.
