Description

The present invention relates to an anti-pesticide for clothing pests.

Conventionally, various insect repellents have been put to practical use mainly for chiffons, drawers, closets and clothing storage boxes in order to protect textile products from garment pests such as moths, cutworms and stains. As its active ingredients, sublimable insect repellents such as p-dichlorobenzene and naphthalene were used in the past, but safety problems and strong irritating odors were pointed out. Recently, room temperature volatile pyrethroids such as empentrin and profluthrin have been pointed out. Insecticides are mainstream. The latter pyrethroid insecticidal component has a high amount of insecticidal effect against clothing pests and is an odorless, highly safe and highly useful active ingredient, but it takes some time to fill the treatment space. Therefore, improvement of the initial effect is desired. Recently, consumer needs have diversified, and there is a tendency to aggressively aromatize treatment spaces and clothing using insect repellents that are somewhat more aromatic than odorless. It was.

Against this background, several proposals have been made to use a natural essential oil-derived component having an insect repellent effect and aroma as an insect repellent component. For example, JP-A-9-278621 (Patent Document 1) is selected from a volatile insect repellent selected from peppermint oil, lemon oil, orange oil, citronellol and poppy oil, and hiba oil, cypress oil, camphor and pinene. Although the description relates to an insect repellent comprising a combination of low volatility insect repellents and exhibits an excellent anti-corrosion effect over a long period of time, the insect repellent effect is not fully satisfactory.
Japanese Patent No. 4148552 (Patent Document 2) discloses three mixtures of carvone, anethole, and linalool as active ingredients of the proliferation inhibitor of clothing pests. However, the effect on clothing pests cannot be said to be sufficient, and an anti-pesticide for clothing pests that uses a natural essential oil-derived component as an anti-powder component and is sufficiently excellent in practicality is still known. Not.

JP-A-9-278621 Japanese Patent No. 4148552

The present invention is an anti-corrosion agent for clothing pests that uses a natural essential oil-derived component or a synthetic perfume component as an anti-corrosion component, and has a high anti-corrosion effect while being excellent in safety for human livestock and yet has a subtle fragrance. An object of the present invention is to provide an anti-pesticide for clothing pests that can enhance the feeling of use.

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

The anti-corrosion agent for clothing pests of the present invention uses a natural essential oil-derived component or a synthetic fragrance component as an anti-corrosion component, and has a high anti-corrosion effect, while being excellent in safety against human livestock and having a subtle fragrance. Since the feeling can be enhanced, its practicality is extremely high.

In the present invention, (a) terpineol, (b) general formula (I)

R ₁ —CH ₂ —COO—CH ₂ —CH═CH ₂ (I)

(Wherein R ₁ represents an alkyl group having 4 to 7 carbon atoms, a cycloalkyl group, a cycloalkylmethyl group, an alkoxy group, a cycloalkoxy group, or an optionally substituted phenoxy group). 1 type (s) or 2 or more types chosen from these allyl ester compounds are used.
Terpineol is widely present in natural essential oils such as turpentine oil, orange oil, neroli oil, geranium oil, hinoki oil and lemon oil. Terpineol has three isomers, α-, β-, and γ-, but only the α-isomer exists in natural essential oils, whereas the commercially available synthetic products are mainly α-isomer, β Many contain-and γ-isomers and a small amount of terpinen-1-ol. In the present invention, each isomer may be used alone or in any mixture.
It is known from, for example, JP-A-1-294601 that terpineol is useful as a repellent component of flying insects.

As the allyl ester compound of the acetic acid derivative represented by the general formula (I), for example, allyl hexanoate, allyl heptanoate, allyl octanoate, allyl cyclohexyl acetate, allyl cyclohexylpropionate, allyl isobutyloxyacetate, allyl n-amyloxyacetate , Allyl isoamyloxyacetate (allylamyl glycolate), allyl isohexyloxyacetate, allyl 3-ethylamyloxyacetate, allyl cyclopentyloxyacetate, allyl cyclohexyloxyacetate (cyclogalvanate), allyl phenoxyacetate, among others. , Allyl hexanoate, allyl heptanoate, allyl octanoate, allyl cyclohexylpropionate, allyl isoamyloxyacetate, allyl cyclohexyloxyacetate, allyl phenoxyacetate , High feeding damage prevention effect, and is suitable because accessible.
In addition, the allyl ester compound of the acetic acid derivative is known as a fragrance component, and among these, allyl isoamyloxyacetate and allyl cyclohexyloxyacetate have a repellent effect against flying insects in Japanese Patent Application Laid-Open No. 2007-119375. Is disclosed.

The present inventors consider that the repellent effect against flying pests and the food damage preventing effect against clothing pests are based on completely different actions, and a combination of terpineol and an allyl ester compound of an acetic acid derivative represented by the general formula (I) As a result of intensive studies, it was found that the combined use of both compounds significantly enhances the effect of preventing damage to clothing pests synergistically, resulting in the completion of the present invention.
The compounding ratio of (a) terpineol and (b) the allyl ester compound of the acetic acid derivative represented by the general formula (I) is preferably 50: 1 to 1:50, which can provide a high synergistic effect.

The above-mentioned anticorrosive ingredients include other natural essential oils and natural or synthetic fragrances such as citronellal, citral, nonanal, geraniol, nerol, borneol, decanol, citronellol, linalool, dihydrolinalool, tetrahydrolinalol, dihydromyrsenol, rosinol. , Menthol, p-menthane-3,8-diol, thymol, menthane, camphene, pinene, limonene, β-ionone, geranyl formate, citronellyl formate, geranyl acetate, citronellyl acetate, neryl acetate, methyl salicylate, citronella oil, cinnamon oil , Eucalyptus oil, lemon eucalyptus oil, hiba oil, lavender oil, orange oil, grapefruit oil, cedarwood oil, geranium oil, thyme white oil, mint oil, etc. It may be combined.

The anti-corrosion agent for clothing pests of the present invention may be composed of only the anti-corrosion components including the above (a) and (b), but is usually prepared in various forms by adding various components. The ratio of the anticorrosive component to the total amount of the anticorrosive agent varies depending on the form of the anticorrosive agent, but for example, when it is liquid, it is preferably set to about 0.5 to 5.0 mass%. If it is less than 0.5% by mass, the effect of preventing food damage is insufficient, while if it exceeds 5.0% by mass, the odor becomes too strong, which is not practical. Moreover, in the case of a gel-like body, about 0.5-10 mass% is suitable for the compounding quantity of a food damage prevention component.

As long as the anti-corrosion agent for clothing pests of the present invention does not interfere with the anti-corrosion effect and safety for human animals, plant-derived deodorant components such as green tea extract and persimmon extract, You may mix | blend another aromatic component for adjustment. For example, green leaf alcohol or green leaf aldehyde called “green fragrance” can be added to give a relaxing effect.
Also, room temperature volatile pyrethroid insecticides such as empentrin, 2,3,5,6-tetrafluorobenzyl-2,2-dimethyl-3- (2,2-dichlorovinyl) cyclopropanecarboxylate [Transflux Thrin], 4-methyl-2,3,5,6-tetrafluorobenzyl-2,2-dimethyl-3- (1-propenyl) cyclopropanecarboxylate [profluthrin], 4-methoxymethyl-2,3,5 If 6,6-tetrafluorobenzyl-2,2-dimethyl-3- (1-propenyl) cyclopropanecarboxylate [methfluthrin] or the like is added, an insecticidal effect can be imparted in addition to the food damage preventing effect.

The anti-corrosion agent for clothing pests of the present invention can adopt various forms such as liquid, gel, solid, and sheet according to the needs of the usage scene.
In preparing the liquid agent, in addition to water, lower alcohols such as ethanol and isopropanol, glycols such as propylene glycol, glycol ether water-soluble organic solvents such as diethylene glycol monobutyl ether and dipropylene glycol monomethyl ether, aliphatic or Aromatic hydrocarbon solvents, surfactants, solubilizers, and dispersants are appropriately used.
Examples of the gelling agent used for preparing the gel-like body include carrageenan, xanthan gum, gellan gum, gelatin, aluminum octylate, and 12-hydroxystearic acid.
On the other hand, cellulose carriers such as pulp, linter and rayon, inorganic porous carriers such as silicate, silica and zeolite, and sublimable carriers such as trioxane and adamantane are impregnated with anti-corrosion ingredients together with solvents if necessary. A solid, sheet-like, granular, etc. anti-corrosion agent can be prepared.
Of course, stabilizers, pH adjusters, colorants, and the like may be added as appropriate.

Next, the liquid form corrosion inhibitor will be described in detail.
As a prescription, 0.5 to 5.0% by mass of an anticorrosive component, 3.0 to 12% by mass of a surfactant, 2.0 to 10% by mass of a solvent such as a lower alcohol or glycol, and water are contained. An aqueous liquid agent is preferable, and this anti-corrosion agent is a method that leads to the evaporation part of the liquid-absorbing material through the liquid-absorbing core to dissipate the anti-corrosion component into the space, a spray method, or an aerosol method with a propellant. It is preferably applied.

As the surfactant, it is preferable that a higher alkylamine oxide surfactant and a nonionic surfactant are used in combination from the viewpoint of stability and dissipative properties of the anticorrosive component.
Examples of higher alkylamine oxide surfactants include laurylamine oxide, stearylamine oxide, lauric acid amidopropyldimethylamine oxide, and the like, while nonionic surfactants include polyoxyethylene hydrogenated castor oil, Examples include polyoxyethylene higher alkyl ether (polyoxyethylene lauryl ether, polyoxyethylene oleyl ether), polyoxyethylene higher fatty acid ester, polyoxyethylene polyoxypropylene alkyl ether, and the like.
If the surfactant is less than 3.0% by mass, solubilization of the corrosion-inhibiting component is poor, and if it exceeds 12% by mass, the dispersibility of the corrosion-inhibiting component may be affected.

Typical examples of the solvent include ethanol, isopropanol, propylene glycol, and the like. For example, in the case of ethanol, if the blending amount is less than 2.0% by mass, the compatibility with the higher alkylamine oxide surfactant is poor. If it exceeds 10% by mass, the danger to fire increases, and it may not be a non-hazardous material under the Fire Service Act.

The anti-corrosion agent for clothing pests thus obtained is applied, for example, to a system in which a container main body having a liquid absorbent wick is filled and the food damaging components are diffused into the space through the liquid absorbent wick.
Here, the material and structure of the container body are not particularly limited, and examples thereof include plastic, glass, and ceramics. A transparent or translucent plastic or glass container in which the amount of liquid inside can be visually confirmed is preferable, and the surface may be processed into a diacut or bohemian cut. Usually, a container body with a capacity of about 50 to 400 mL is practical. And the bottom part of a container main body should comprise the contact part of the liquid absorption core mentioned later somewhat concavely so that a liquid agent may be sucked up without remaining.
An inner plug for holding the liquid absorbent core is attached to the opening at the top of the container body. The inner plug is preferably made of plastic, and if it is formed in a cylindrical shape downward from the crowning position of the opening and the liquid absorbent core is inserted, it is more preferable because the liquid absorbent core can be securely held.

The liquid absorbent core is one that is stable with respect to an anticorrosive agent and absorbs an aqueous solution by capillary action. Specific examples of the material include plastic fibers such as nylon and polyester, natural fibers, and wood. Of these, a felt absorbent core made of plastic fiber or natural fiber is easy to use, and is formed into a rod shape or a twisted core shape having an outer diameter of about 3 to 10 mm and is used.

Usually, an evaporating part for dissipating the sucked-up food damage preventing agent is provided on the upper part of the liquid absorbent core. The structure of the evaporating part is felt or sheet-like, and the material thereof can be, for example, plastic fibers such as nylon and polyester, natural fibers, wood, etc., as in the case of the liquid absorbent core. Of these, a plastic fiber or natural fiber felt or sheet-like material is preferable, and it is formed into a substantially circular shape having a thickness of 2 to 15 mm and a surface area of 10 to 60 cm ² , and this is in contact with the top surface of the liquid absorbent core. If it arrange | positions, the sucked-up anticorrosive agent will transfer to an evaporation part from a liquid absorption core, and will be gradually diffused in the air from here. If the surface area of the evaporating part is less than 10 cm ² , the amount of evaporation tends to be low, while if it exceeds 60 cm ² , the amount of evaporation is excessive, which may cause a problem in sustainability. Usually, the amount of evaporation of the anti-corrosion agent in the air per day is 0.5 to 5 mL, and the effective duration is adjusted to about 3 to 6 months.
Moreover, it is common to provide the evaporation part support body, or to provide a mesh-like lid member that covers the evaporation part so that a finger or the like does not touch the evaporation part.
Furthermore, in order to impart interior properties, cloth or plastic artificial flowers or figures may be loaded through the evaporation unit support.

It can be prepared in accordance with conventional methods even when the insecticide for clothing pests is in the form of a gel, solid, sheet, etc., and preparations suitable for the purpose and use (fan type insect repellent, insect repellent, etc.) It is possible to efficiently dissipate the anti-corrosion component into the space by applying to the above.
As described above, the anti-corrosion agent for clothing pests according to the present invention is a practical anti-corrosion prevention against clothing pests such as squid, koiga, himemekaobushimushi, himemarukatsushimushi, and shime, in chiffons, drawers, closets, warehouses and closets. In addition to having an effect, it also has a practical insect repellent effect against flying insects such as mosquitoes such as mosquitoes, chikaeka, and mosquitoes, moths, chironomids, flies and butterflies. In addition, according to the anti-pesticide for clothing pests of the present invention, it is possible to fully enjoy the aroma feeling simultaneously with the practical anti-pesticide effect over a long period of 3 to 6 months, and its practicality is extremely high.

Next, based on a specific Example, the clothing insect pest prevention agent of this invention is demonstrated in detail.

0.15% by mass of terpineol, 0.75% by mass of allyl ester compound of acetic acid derivative (allyl octanoate: 0.60% by mass, allyl cyclohexylpropionate: 0.10% by mass, allyl isoamyloxyacetate: 0.05) Mass%), citronellal 0.10 mass%, laurylamine oxide 1.2 mass%, polyoxyethylene hydrogenated castor oil 1.6 mass%, polyoxyethylene oleyl ether 3.0 mass%, ethanol 7 mass% Inhibitor of clothing pests according to the present invention containing 0.0% by mass, 1.0% by mass of green tea extract component as deodorant, 0.02% by mass of citric acid, and 85.18% by mass of purified water Was prepared. The mixing ratio of terpineol and allyl ester compound in this anti-corrosion agent was 1: 5, and this aqueous preparation corresponded to a non-hazardous material under the Fire Service Law.
The transparent polyester container body was filled with 130 g of the clothing pest anti-corrosion agent of the present invention, and an inner plug having an outer diameter of 7 mm and a rod-shaped felt absorbent core inserted therein was crowned. A plate-shaped felt evaporation part having a thickness of 5 mm and a diameter of 5.2 cm was attached in contact with the top surface of the liquid-absorbing core to produce a stationary insect-proof device.
When this insect repellent device was used in a closet having a volume of 1800 L, it was possible to fully enjoy the fragrance for about 6 months, and the storage clothing was not damaged by clothing pests.

1.2 g of terpineol, 0.3 g of allyl ester compound of acetic acid derivative (allyl cyclohexylpropionate: 0.2 g, allyl heptanoate: 0.1 g), 0.8 g of eucalyptus oil and 4-methyl-2,3, To a mixture containing 0.1 g of 5,6-tetrafluorobenzyl-2,2-dimethyl-3- (1-propenyl) cyclopropanecarboxylate, 2.0 g of a gelling agent (aluminum octylate), diethylene glycol butyl ether 0 g and 114.6 g of isoparaffinic hydrocarbons were added to prepare 120 g of a gel-like garment pest inhibitor.
This was filled in a polyester container, and a lid member having a 40% perforated area was attached to the upper opening of the container to produce a gel-type insect repellent device.
In the same manner as in Example 1, this insect repellent device, in the library, not only prevents feeding damage caused by clothing pests such as squid, koiga, Himekatsuobushimushi, Himemarukatsushimushi, and stains, but also has a repellent effect on flying insects such as mosquitoes and moths. outstanding.

According to Example 1, various anti-corrosion agents shown in Table 1 (however, surfactants, solvents, and water are omitted) were prepared, and 0.5 mL thereof was impregnated into a filter paper having a diameter of 3 cm, dried, and the following: An anti-corrosion test was conducted.
[Eating damage prevention test]
Place the test filter paper on the bottom of a glass bottle with a capacity of 500 mL, and place 10 moth larvae with an average weight of 30 to 35 mg / head and a wool test cloth (2 cm x 2 cm, 40 to 45 mg) 5 cm above it. The basket was fixed. Next, after sealing the glass bottle and leaving it in a constant temperature and humidity room at 27 ° C. and a humidity of 65% for 7 days, the wool test cloth was taken out and the damage rate (damage amount / original weight × 100) was measured. The insect rate was determined. The results are shown in Table 2.

As a result of the test, the anti-corrosion agent for clothing pests according to the present invention exhibits an excellent anti-pesticide effect and insecticidal effect on clothing pests based on the synergistic effect of terpineol and an allyl ester compound of acetic acid derivative blended as an anti-corrosion component. It was recognized that
On the other hand, as shown in Comparative 1 to Comparative 3, in the case of terpineol or the allyl ester compound alone, the effect of preventing food damage is inferior, and terpineol and carvone (a food damage preventing component other than allyl ester compounds of acetic acid derivatives) are combined. In Comparative Example 4, the food damage prevention effect was not expressed synergistically.

The present invention can be used not only in the clothing field but also in a wide range of pest control fields.
