Description

  The present invention relates to an insect repellent for clothing used in a chiffon, a drawer, a closet, a clothing storage box and the like.

  Various insect repellents have been put to practical use in order to protect textile products from clothing pests such as moths, cutlet worms, and stains. In the past, sublimable insecticidal components such as p-dichlorobenzene and naphthalene have been used as active ingredients of insect repellents. However, in recent years, room temperature volatile pyrethroid insecticides such as empentrin and profluthrin have volatility at room temperature , Simply referred to as “pyrethroid insecticide”). Recently, consumer needs have diversified, and there is a tendency to positively perfume the treatment space and clothing by using an insect repellent that is somewhat aromatic than odorless. When a fragrance component is used in combination with an insecticidal component, a pyrethroid type insecticidal component that is less irritating is advantageous.

  The pyrethroid insecticidal component has an advantage that it exhibits a high insecticidal effect in a small amount against clothing pests and is excellent in safety to the human body. On the other hand, since a pyrethroid insecticide component requires a certain amount of time until the treatment space is filled, a sufficient insecticidal effect may not be obtained in the initial stage of use depending on the situation.

  With respect to insect repellents, several proposals have been made in which pyrethroid insecticide ingredients and perfume ingredients are used in combination. For example, a pest control composition containing a mixture of two different high vapor pressure pest control components as an active ingredient has been developed (see, for example, Patent Document 1). In Patent Document 1, the first high vapor pressure pest control component contains a pyrethroid compound as an insecticidal component, and the second high vapor pressure pest control component contains a terpene as a fragrance component. Compositions are shown.

  In addition, clothing pest growth inhibitors containing a terpene compound as an active ingredient are also known (see, for example, Patent Document 2). Patent Document 2 shows that an excellent insecticidal effect is exhibited by using a terpene compound and a pyrethroid compound in combination.

JP-A-3-44305 JP 11-269909 A

  Pyrethroid insecticides such as empentrin gradually evaporate when they are used, and the insecticidal effect lasts for about 6 to 12 months under normal use. On the other hand, the terpene compound used as a fragrance component has higher volatility from the start of use than the pyrethroid insecticide component. Therefore, as in Patent Documents 1 and 2, when a pyrethroid insecticidal component and a terpene compound are used in combination, the pyrethroid insecticidal component takes a while to exhibit a sufficient insecticidal effect, whereas the terpene system Since the compounds are volatilized from the initial stage of use, the insect repellent effect decreases with time. As a result, it is difficult to continue to exert enhanced insecticidal and insecticidal effects (synergistic effect of the pyrethroid insecticidal component and the terpene compound) over the entire duration of the pyrethroid insecticidal component.

  The present invention has been made in view of the above-mentioned problems, and is used for clothing having fragrance capable of continuing to exhibit enhanced insecticidal and insecticidal effects over the entire duration of the pyrethroid insecticidal component. It aims at providing an insect repellent.

The characteristic configuration of the insect repellent for clothing according to the present invention for solving the above problems is as follows:
(A) p-tert-butylcyclohexyl acetate as an insect repellent component;
(B) as Lupi Resuroido insecticide component having a volatile at ambient temperature, and empenthrin,
It is to include.

In the present invention, the blending ratio ((a) :( b)) of p-tert-butylcyclohexyl acetate and empentrin is preferably 0.01 : 1 to 0.2 : 1 by weight.

In the present invention, it is preferable that (c) the second insect repellent fragrance component contains carvone .

In the present invention, as persistent perfume ingredients having a longer lasting than; (d) insect perfume ingredients, preferably contains Garakusori de.

In the present invention, p-tert-butylcyclohexyl acetate and mixing ratio of the empenthrin ((a) :( b)) is 0.04 weight ratio: 1 to 0.14: 1, the Garakusorido and empenthrin The blending ratio ((d) :( b)) is preferably 0.01 : 1 to 0.29 : 1 by weight.

Fabric protectant agent of the present invention, as pyrethroid insecticidal ingredients with volatile at p-tert-butylcyclohexyl acetate and cold as insect perfume ingredients, by combining the empenthrin, throughout the duration of empenthrin p- Tert-butyl cyclohexyl acetate can be allowed to act. As a result, by the synergistic effect of the insect repellent according pesticidal effect and p-tert-butylcyclohexyl acetate by empenthrin, an enhanced effect it is possible to continue to exert a long term. In addition, by adding p-tert-butylcyclohexyl acetate , the added value of the product is increased as an insect repellent for clothing to which fragrance has been imparted over a long period of time. Further, by adding carvone as the second insect repellent component, the fragrance is further enhanced, and the insect repellent effect at the initial stage of use is particularly enhanced. Further, by adding galaxolide as a long-lasting fragrance component , it is possible to further enhance the enhanced insect repellent effect and fragrance. Since p-tert-butylcyclohexyl acetate , carvone , and galaxolide combined with empentrin are highly safe for human livestock, the insect repellent for clothing of the present invention is suitable for home use and has excellent practicality.

  Hereinafter, the insect repellent for clothing of the present invention will be described. However, the present invention is not intended to be limited to the embodiments described below.

  First, in the present specification, as an effect of eliminating clothing pests, an effect mainly derived from an insecticidal component is expressed as an “insecticidal effect”, and an effect mainly derived from a perfume component is expressed as an “insecticidal effect”. In addition, the “insecticidal effect” and “insect-proofing effect” in this specification are not only the effects of killing larvae and adults of clothing pests, but also the repellent effect of keeping clothes pests away, the effect of preventing entry into clothing, etc. It means a comprehensive effect that includes prevention effects.

  As a result of intensive studies by the present inventors, in an insect repellent for clothing containing a pyrethroid insecticidal component having volatility at room temperature, acetic acid is used as an insect repellent component in order to enhance the insecticidal effect and insect repellent effect from the initial use stage. It has been found effective to contain an ester compound. Here, “has volatility at normal temperature” means that it exhibits a vapor pressure of 0.001 Pa or higher at 25 ° C., and if the volatilization amount is 0.005 mg / Hr or higher, it is volatile at normal temperature. Can be considered as having

The insect repellent for clothing of the present invention has the following formula (I) as (a) insect repellent component:
CH ₃ —COO—R (I)
(R: an alcohol residue having 6 to 12 carbon atoms)
And (b) one or more pyrethroid insecticidal components having volatility at room temperature. Furthermore, the insect repellent for clothing of the present invention comprises (c) a second insect repellent component, and (d) a persistent perfume component having a longer persistence than the insect repellent component in addition to the insect repellent component and the pyrethroid insecticide component. It can be prepared to contain. Hereinafter, each component will be described.

(A) Insect repellent component The specific acetate compound represented by the formula (I) used as the insect repellent component is an ester compound that is chemically similar to a pyrethroid-based insecticidal component described later. The volatility of the acetate compound is generally equivalent to the volatility of the terpene compound that can be added as a second insect repellent component described later, and has the property that it is greater than the volatility of the pyrethroid insecticide component. For this reason, the acetic acid ester compound can exhibit an enhanced insect repellent effect by a synergistic effect over a long period of several months or more from the initial stage of use in cooperation with the pyrethroid insecticide component. In addition, the aromaticity is enhanced by the acetate compound during the duration of the insect repellent for clothing. Therefore, by adding the insect repellent component, the added value of the product is increased as an insect repellent for clothing to which fragrance has been imparted over a long period of time.

  The alcohol residue (R) in the acetate compound represented by the formula (I) includes a cycloalkyl group that can be substituted with an alkyl group having 1 to 5 carbon atoms, and a phenylalkyl having 1 to 3 carbon atoms. Examples include a group (having 1 to 3 carbon atoms between the phenyl group and the ester group), a terpene alcohol residue, and the like. That is, as the acetate compound, p-tert-butylcyclohexyl acetate, o-tert-butylcyclohexyl acetate, p-tert-pentylcyclohexyl acetate, tricyclodecenyl acetate, benzyl acetate, phenylethyl acetate, styrylyl acetate, Examples include silacetate, cinnamyl acetate, terpinyl acetate, dihydroterpinyl acetate, linalyl acetate, ethyl linalyl acetate, citronellyl acetate, geranyl acetate, neryl acetate, bornyl acetate, and isobornyl acetate. Of these, suitable acetate compounds are p-tert-butylcyclohexyl acetate, o-tert-butylcyclohexyl acetate, tricyclodecenyl acetate, benzyl acetate, terpinyl acetate, dihydroterpinyl acetate, and ethyl. Linalyl acetate. These acetate compounds can be used alone, but may be used as a mixture of two or more.

(B) Pyrethroid-based insecticidal component Examples of pyrethroid-based insecticidal components used in combination with the above-mentioned insect repellent component include empentrin, profluthrin, transfluthrin, metfurthrin, and terareslin. These pyrethroid insecticide components can be used alone, but may be used as a mixture of two or more. In addition, these pyrethroid insecticides include optical isomers and geometric isomers based on asymmetric carbon and double bonds, and these can be used alone or in any mixture.

(C) Second insect repellent component The insect repellent for clothing of the present invention may contain a terpene compound as a second insect repellent component in order to further enhance the insect repellent effect in the initial stage of use. It was confirmed by the present inventors that when the terpene compound is used in combination with the above insect repellent fragrance component, the insect repellent effect at the initial use stage lasts for a long time. Moreover, the terpene compound also has a function as a fragrance, and therefore, it is possible to increase the fragrance over a longer period. Examples of terpene compounds include terpene alcohols such as terpineol, citronellol, geraniol, nerol, linalool, dihydrolinalol, tetrahydrolinalol, dihydromyrcenol, menthol, borneol, and isoborneol, and terpene aldehydes such as citronellal, citral, and dimethyloctanal. , Terpene ketones such as carvone, dihydrocarvone, pulegone and menthone. These terpene compounds can be used alone, but may be used as a mixture of two or more. The terpene compound may be in the form of a plant essential oil containing the terpene compound. Plant essential oils include citronella oil, orange oil, lemon oil, lime oil, yuzu oil, lavender oil, peppermint oil, cinnamon oil, eucalyptus oil, lemon eucalyptus oil, hiba oil, grapefruit oil, cedarwood oil, geranium oil, thyme white Oil, mint oil, jasmine oil, cocoon oil, green tea essential oil and the like.

(D) Long-lasting perfume ingredient The insect repellent for clothing of the present invention may contain a long-lasting perfume ingredient in order to further enhance the insect-repellent effect and perfume persistence. In addition to the above-mentioned insect repellent and second insect repellent components, the use of a long-lasting perfume component reduces the decrease in insect repellent effect in the later stage of use, and can withstand long-term use of 6 to about 12 months Insect repellents can be realized. Examples of long-lasting perfume ingredients include galaxolide, musk ketone, hexylcinnamic aldehyde, ethylene brushate, methyl atrate, hexyl salicylate, oranger crystal, and the like. These persistent perfume ingredients can be used alone, but may be used as a mixture of two or more.

[Composition of insect repellent for clothing]
The blending ratio ((a) :( b)) of the insect repellent fragrance component and the pyrethroid insecticide component is preferably 0.02: 1 to 0.4: 1 by weight. If it is this range, an insect repellent perfume ingredient can be made to act over the whole duration of a pyrethroid type insecticide ingredient, strengthening the insect repellent effect in the use initial stage of the insect repellent for clothes with an insect repellent perfume ingredient. As a result, the enhanced effect and aromaticity can continue to be exhibited over a long period of time due to the synergistic effect of the insecticidal effect of the pyrethroid insecticidal component and the insect repellent effect of the insect repellent component. Even if the blending ratio of the insect repellent component and the pyrethroid insecticide component ((a) :( b)) exceeds the above range, the synergistic effect between the insecticide effect by the pyrethroid insecticide component and the insect repellent effect by the insect repellent component has reached its peak. I cannot expect much improvement of the effect. When the blending ratio of the insect repellent component and the pyrethroid insecticide component ((a) :( b)) is below the above range, a sufficient synergistic effect between the insecticide effect by the pyrethroid insecticide component and the insect repellent effect by the insect repellent component is sufficiently obtained. It may not be possible.

  The blending ratio ((d) :( b)) of the long-lasting perfume component and the pyrethroid insecticide component is preferably 0.02: 1 to 0.4: 1 by weight. Within this range, in addition to the above insect repellent component, the long-lasting perfume component can act over the entire duration of the pyrethroid insecticide component while extending the period of use of the insect repellent for clothing with the long-lasting perfume component. it can. As a result, the synergistic effect of the insecticidal effect of the pyrethroid insecticidal component and the insecticidal effect of the insecticidal perfume component and the persistent perfume component makes it possible to continue to exhibit further enhanced effects and fragrance for a longer period of time. . When the blending ratio ((d) :( b)) of the persistent perfume ingredient and the pyrethroid insecticide exceeds the above range, the volatilization amount of the pyrethroid insecticide is suppressed, and the insecticidal effect is sufficient over the period of use. May not be obtained. If the blending ratio ((d) :( b)) of the long-lasting perfume ingredient and the pyrethroid-based insecticidal ingredient is below the above range, the use of the long-lasting perfume ingredient may not be sufficiently extended. is there.

  The insect repellent for clothing of the present invention may contain various additives in addition to the above components. For example, antifungal agents (2-phenylphenol (OPP), 4-isopropyl-3-methylphenol (IPMP), 2-n-octyl-4-isothiazolin-3-one, isopropylmethylphenol, orthophenylphenol, etc.), Antibacterial agents (hinokitiol, eugenol, allyl isothiocyanate, etc.), fragrances (limonene, α-pinene, phenylethyl alcohol, amylcinnamic aldehyde, benzyl acetate, etc.), disinfecting components, stabilizers such as BHT, pH adjusters , Coloring agents, hydrocarbon compounds (hexane, paraffin, etc.), various petroleum solvents, and the like can be appropriately contained. In addition, a fragrance such as green leaf alcohol or green leaf aldehyde called “green scent” may be contained as appropriate. By adding a green scent to the insect repellent for clothing, a relaxation effect can be imparted to the user when the clothing storage container is opened.

  The amount of the insect repellent perfume component and the pyrethroid insecticidal component in the insect repellent for clothing is about 0.004 to 0.4 g of the insect repellent perfume component and 0.02 to 1 for the pyrethroid insecticide per one insect repellent for clothing. About 0.0 g is preferable. The amount of the insect repellent component and the pyrethroid insecticide component can be appropriately adjusted according to the dosage form of the insect repellent for clothing. When the blending amount of the insect repellent component and the pyrethroid insecticide component is less than the above range, a sufficient insecticidal effect and insect repellent effect may not be obtained. When the blending amount of the insect repellent and the pyrethroid insecticide exceeds the above range, the usability is deteriorated due to a sticky feeling or the like, and the practicality is lowered.

[Dosage form of insect repellent for clothing]
The dosage form of the insect repellent for clothing of the present invention may be selected from various states such as a liquid, a gel, and a solid according to the usage scene.

  When preparing a liquid material, water, alcohol solvents (ethanol, isopropanol, etc.), glycol solvents (1,3-butylene glycol, propylene glycol, dipropylene glycol, etc.), glycol ether solvents (diethylene glycol) are used as the solvent. Monobutyl ether, propylene glycol monomethyl ether, etc.), aliphatic hydrocarbon solvents, surfactants (solubilizers), and the like may be used as appropriate. Among these, as the surfactant, polyoxyethylene hydrogenated castor oil, polyoxyethylene higher alkyl ether (polyoxyethylene lauryl ether, polyoxyethylene oleyl ether, etc.), polyoxyethylene higher fatty acid ester, nonionic surfactant (Polyoxyethylene polyoxypropylene alkyl ether and the like), higher alkylamine oxide surfactants (laurylamine oxide, stearylamine oxide, lauric acid amidopropyldimethylamine oxide and the like) and the like.

  When preparing a gelled material, carrageenan, xanthan gum, gellan gum, gelatin, aluminum octylate, 12-hydroxystearic acid and the like can be appropriately used as a gelling agent.

  When preparing a solid product, a solid carrier is impregnated or held with an insect repellent prepared as a liquid or gel. The active ingredient of the insect repellent for clothing is volatilized from the solid carrier, thereby exhibiting an insecticidal effect and an insect repellent effect. Solid carriers include fibrous carriers (pulp, linter, rayon, etc.), cellulose or regenerated cellulose beads and foams, inorganic porous carriers (silicate, silica, zeolite, etc.), sublimable carriers (trioxane, adamantane) Etc.). When a fibrous carrier is used, a mat or sheet having a thickness of about 1 to 3 mm is preferable. When cellulose beads are used, a deodorizing effect can be imparted to the insect repellent for clothing by incorporating a porous material such as charcoal therein.

[Usage of insect repellent for clothing]
The insect repellent for clothing of the present invention is commercialized in a state of being accommodated in a container such as a breathable bag or a breathable case. For example, pellets and beads manufactured by impregnating a solid carrier with an insect repellent for clothing are enclosed in a breathable bag to constitute an insect repellent for bags. This bag-containing insect repellent is placed in a chiffon, closet, drawer, clothing storage box, etc., and the volatilizing component contained in the clothes insect repellent is volatilized around through the breathable bag. The number of clothing insect repellents varies depending on the installation environment, but about 1 to 3 per site is sufficient for normal use. Examples of the breathable bag used for the bag-containing insect repellent include a non-woven bag, a woven bag, a cotton bag, a paper bag, a net case, etc. Among these, a non-woven bag is particularly preferable. Examples of the material of the nonwoven fabric bag include polyester (PET), polyethylene (PE), polypropylene (PP), polyamide (PA), polylactic acid (PL), and rayon. It does not matter whether the fibers constituting the nonwoven fabric bag are single fibers or blended products. Moreover, you may comprise a nonwoven fabric bag with the laminated goods which laminated | stacked the porous sheet (for example, paper, a porous resin sheet, etc.) on the fiber sheet. If it is such a laminated product, the volatilization component of the insect repellent for clothing is partially adsorbed on the porous sheet when passing through the nonwoven fabric bag, and as a result, the volatilization amount of the volatilization component is adjusted secondarily. Is possible.

  When the insect repellent for clothing is used in a breathable case, the insect repellent for clothing is stored in the breathable case as it is or enclosed in the breathable bag. A plurality of vent holes through which the volatile component can pass are formed in the breathable case. The breathable case can be produced, for example, by molding a thermoplastic resin. When resin molding is performed, the breathable case may be molded as a single body, but a plurality of parts may be molded with resin and the breathable case may be configured by combining them. A hook for hanging on a hanger pipe or the like of a closet can be formed at the same time in the breathable case. Examples of the molding method for the breathable case include hot plate pressure molding, injection molding, blow molding, mold molding, and insert molding. 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).

  Insect repellents for clothing constructed as described above include clothing pests (Iga, Koiga, Himekatsuobushimushi, Himemarukabushimushi, worms, etc.), indoor dust mites (Mite mites, leopard mites, dust mites, claw mites, etc.) , Tubers, cockroaches, ants, mosquitoes, moths, chironomids, flies, butterflies, etc.) for a practical period of 3-12 months from the initial use stage to the final use stage Can exert insecticidal and insecticidal effects. In addition, as for aromaticity, since the high aromaticity in the initial stage of use is maintained as it is for a long period of time due to the action of the insect repellent component, the second insect repellent component, and the persistent perfume component, It is suitable for use and has high practicality.

In order to confirm the effect of the insect repellent for clothing of the present invention, an insect repellent mat was prepared by impregnating a pulp paper having an area of 11 cm ² and a thickness of 1 mm with the insect repellent for clothing prepared as a liquid. Using this insect repellent mat, the following food damage prevention efficacy test and aroma persistence test were conducted.

[Eating damage prevention test]
A costume box with a capacity of 50 L was prepared, a test insect mat was placed inside, and the costume box was sealed with a lid. This costume box was stored in a room at a temperature of 27 ° C. and a humidity of 65%, and was subjected to a food damage prevention efficacy test. In the test, at the time of 1 month, 1 month and 3 months immediately after the start, the cover of the costume box is opened, 10 cm above the insect-proof mat, 20 moth larvae weighing 30 to 35 mg / head at 30 days and wool test cloth (2 cm × 2 cm, 40 to 45 mg) was placed and left for 7 days, after which the woolen test cloth was collected from the cage, and the damage rate (damage amount / original weight × 100) was measured. The mortality was determined.

[Aromatic duration test]
When the lid of the clothing box was opened in the eating damage prevention efficacy test, the change in fragrance from the standard sample corresponding to the insect-proof mat at the start of the test was evaluated by a sensory test with 10 monitors. The evaluation criteria are “◯” when 8 or more people do not feel a change in fragrance, “△” when 3 to 5 people feel a change in fragrance, and “6” when 6 or more people feel a change in fragrance clearly. × ”.

<Examples 1-8>
As Examples 1 to 8, according to the present invention, an insect repellent for clothing containing (a) an acetic ester compound represented by the above formula (I) as an insect repellent component and (b) a pyrethroid insecticide component was prepared. . Among these, Examples 1 to 6 and 8 were prepared by further containing (c) a terpene compound as a second insect repellent and / or other components. For comparison, an insect repellent for clothing having a composition outside the scope of the present invention was prepared (Comparative Examples 1 to 4) and subjected to the same test as in the Examples. Examples 3 to 8 are shown as reference examples. Table 1 shows the compositions of the insect repellents for clothing used in Examples 1 to 8 and Comparative Examples 1 to 4.

This insect repellent for clothing was placed on the clothes being pulled out, and subjected to a food damage prevention effect test and a fragrance sustaining test. As a result, it was confirmed that the insect-repellent effect against clothing pests such as squid, koiga, Himekatsuobushimushi, Himemarukatsubushimushi was not brought close to for about 6 months from the start of use. In addition, the initial fragrance persisted without change during the period.

<Examples 10 to 17>
As Examples 10 to 17, according to the present invention, (a) an acetate ester compound represented by the above formula (I) as an insect repellent component, (b) a pyrethroid insecticidal component, and (d) a persistent flavor component A garment repellent was prepared. Among these, about Example 10 and 13-16, it prepared as what further contains the terpene compound as a (c) 2nd insect repellent fragrance | flavor component, and / or another component. For comparison, an insect repellent for clothing having a composition outside the scope of the present invention was prepared (Comparative Examples 5 to 8) and subjected to the same tests as in Examples. In addition, Comparative Examples 5-8 are the same tests as Comparative Examples 1-4. Examples 13 to 17 are shown as reference examples. The composition of the insect repellent for clothing used in Examples 10 to 17 and Comparative Examples 5 to 8 is shown in Table 3.

  Table 4 shows the results of the food damage prevention efficacy test and the fragrance sustainability test using the insect repellents for clothing of Examples 10 to 17 and Comparative Examples 5 to 8.

  From the results of Examples 10 to 17, the insect repellent for clothing of the present invention was found to have a high food damage prevention effect immediately after the start of the test and to 8 months later, and the death rate also finally reached 100%. In other words, in addition to the synergistic effect of the insecticidal effect of the pyrethroid-based insecticidal component and the insecticidal effect of the insecticidal perfume component, the sustained effect of the persistent perfume component also overlaps, confirming that the enhanced effect will continue to be exhibited over a longer period of time It was done. In addition, the fragrance persistence was not significantly reduced from immediately after the start of the test to 8 months later. Furthermore, it was confirmed that the insect repellent for clothing of the present invention enhances the insect repellent effect and aromaticity in the initial stage of use. In Examples 10-17, the mixture ratio ((a) :( b)) of the acetic ester compound which is an insect repellent perfume component and a pyrethroid type insecticidal component is the range of 0.02: 1-0.4: 1 by weight ratio. In the above, a practical effect is seen when the blending ratio ((d) :( b)) of the persistent fragrance component and the pyrethroid insecticide component is in the range of 0.02: 1 to 0.4: 1 by weight ratio. It was.

  On the other hand, the insect repellent for clothing not containing an acetate ester compound (Comparative Example 5) was inferior in the insect repellent effect at the initial use stage. The insect repellent for clothing that does not contain a pyrethroid insecticidal component (Comparative Example 6) could not exhibit the insecticidal effect and the insect repellent effect to a practical level. In the insect repellent for clothing containing the pyrethroid insecticidal component and the highly volatile acetic ester compound outside the scope of the present invention (Comparative Example 7), the synergistic effect of both is not sufficient, and the insect repellent effect at the initial stage of use and The aromaticity could not be sustained.
