Description

The present invention relates to a deodorizing composition and a deodorizing method for deodorizing a malodor derived from a malodorous pest, a composition for controlling a malodorous pest, and a method for controlling a malodorous pest.

Stink bugs, which are typical of pests that emit foul odors (hereinafter referred to as "foul odor pests"), not only become agricultural pests because they have a sucking property on crops, but also invade warm indoors in groups or dry for wintering. Since it often adheres to the existing laundry and invades indoors together with the taken-in laundry, it is desirable to exterminate it as an unpleasant pest in the house. In particular, the secretions secreted by stink bugs when they feel a danger have a very strong foul odor, so it is important to take measures against the foul odor in the extermination of houses. It is also known that bed bugs, which are closely related to stink bugs, emit the same foul odor as stink bugs, and measures against the foul odor are required for the extermination of bed bugs.

For example, there is an aerosol agent that prevents a foul odor when exterminating stink bugs (see Patent Document 1). The aerosol agent of Patent Document 1 exterminates pests before secreting secretions by knocking down or letting stink bugs within 3 seconds from the start of spraying.

Hereinafter, the deodorant composition and the deodorant method of the present invention, the composition for controlling malodorous pests, and the method for controlling malodorous pests will be described. However, the present invention is not intended to be limited to the configurations described in the embodiments described below.

<Deodorant composition>
The deodorant composition according to the present invention is for deodorizing the malodor derived from the malodorous pest, and is a fragrance that deodorizes the malodor released from the insect body at the time of extermination of the malodorous pest and the carcass after extermination. Contains ingredients. Examples of malodorous pests include stink bugs, bed bugs, cockroaches, bugs, beetles, longhorn beetles, longhorn beetles, millipedes, etc. Among them, stink bugs and bed bugs are unpleasant pests in their homes. There is a high demand from consumers to deodorize the malodors derived from these malodorous pests.

The malodor emitted by malodorous pests is a complex odor, and it is difficult to prepare a large amount from insect bodies such as stink bugs for testing. As the causative substances of malodor, trans-2-hexenal, trans-2-decenal, and tridecane were identified. By mixing these, a simulated stink bug malodor liquid that faithfully reproduces the stink bugs emitted by stink bugs was prepared, and the compatibility with various fragrances was examined in detail. It was found that deodorization can be achieved by modulation or masking. Based on this new finding, as a result of adding a specific kind of fragrance as a fragrance component to the deodorant composition, an excellent deodorizing effect was recognized.

Malodor modulation (harmonized) is the conversion of a malodor into a good scent by incorporating it as one of the components of the scent. Be perceived. Perfume components that modulate the malodor emitted by malodorous pests include, for example, allyl cyclohexanepropionate, maltor, vanillin, α, 3,3-trimethylcyclohexanemethanolformate, 1-hexanol, ethyl 2-methylpentane, and hexyl acetate. , Terpineol, lime oil, benzyl alcohol, β-naphthylmethyl ether, linalol, p-simene, and limonene. Methanolformate, 1-hexanol, ethyl 2-methylpentaneate, hexyl acetate, terpineol, lime oil, and benzyl alcohol are preferred.

Odor masking is a deodorizing effect that suppresses the perception of offensive odors due to the aroma of fragrances. Fragrance components that mask the malodor emitted by malodorous insects include, for example, isoamyl butyrate, isoamyl acetate, prenyl acetate, citral, methyl heptenone, ethyl phenyl acetate, nonanal, dihydromilsenol, γ-terpinen, eucalyptus oil, and cis-. Examples thereof include 3-hexenol, cuminaldehyde, and octanal, and isoamyl butyrate, isoamyl acetate, prenyl acetate, citral, methyl heptenone, ethyl phenylacetate, nonanal, dihydromilsenol, and γ-terpinene, which have excellent masking effects, are particularly preferable. ..

As the fragrance component of the present invention, a fragrance component that modulates the malodor emitted by the above-mentioned malodorous pest and / or a perfume component that masks the malodor emitted by the malodorous pest is used, but these perfume components are used alone. It may be used, or a plurality of kinds may be used in combination. The content of the fragrance component in the deodorant composition is 0.005% by weight or more, preferably 0.01 to 5% by weight. Within such a range, excellent deodorant properties can be exhibited against malodors derived from malodorous pests. If the content of the fragrance component in the deodorizing composition is less than 0.005% by weight, the deodorizing property against the malodor derived from the malodorous pest may be insufficient. The upper limit of the content of the fragrance component in the deodorant composition is not particularly limited in terms of the deodorizing performance against the malodor derived from the malodorous pest, but when the perfume component becomes excessive, the deodorant composition is used. When treated in a closed space, the odor of the fragrance component becomes stronger, which may cause discomfort due to the fragrance component. Therefore, in reality, it is desirable to set the content to 5% by weight or less.

In addition to the above components, the deodorant composition of the present invention contains antifungal agents, antibacterial agents, bactericidal agents, antistatic agents, etc. for fungi and fungi, as long as the effects of the present invention are not hindered. A pH adjuster, an antifoaming agent and the like can be appropriately added. Examples of fungicides, antibacterial agents, and fungicides include hinokitiol, 2-mercaptobenzothiazole, 2- (4-thiazolyl) benzimidazole, 5-chloro-2-methyl-4-isothiazolin-3-one, triphorin, 3 -Methyl-4-isopropylphenol, ortho-phenylphenol and the like can be mentioned.

In the deodorant composition of the present invention, each of the above components is blended in an appropriate weight ratio, and water, a hydrocarbon solvent such as kerosene, and alcohols are added so that the concentration of each component becomes appropriate. Prepared for. As the alcohols, lower alcohols having 2 to 3 carbon atoms are preferable, and ethanol is particularly preferable.

<Composition for controlling malodorous pests>
The composition for controlling malodorous pests according to the present invention contains an insecticidal component and a fragrance component that suppresses malodor derived from malodorous pests. Can be prepared.

As the insecticidal component, an component effective for exterminating malodorous pests is used. Examples of such components include pyrethroid insecticides, neonicotinoid insecticides, and carbamate insecticides. Examples of pyrethroid insecticides include transfluthrin, profluthrin, metoflutrin, empentrin, phthalthrin, resmethrin, cyphenothrin, phenothrin, permethrin, cyphenothrin, cypermethrin, arereslin, prarethrin, flamethrin, imiprothrin, and etofenprox.

Examples of neonicotinoid insecticides include dinotefuran, acetamiprid, imidacloprid, clothianidin, thiacloprid, thiamethoxam, and nitenpyram. Carbamate insecticides include propoxul, carbyl, methomyl, and thiodicalve. Some pyrethroid insecticides, neonicotinoid insecticides, and carbamate insecticides have optical isomers and geometric isomers based on asymmetric carbon, but these isomers are also insecticidal components. included. These pyrethroid insecticides, neonicotinoid insecticides, and carbamate insecticides may be used alone or in combination of two or more. The content of the insecticidal component in the composition for controlling malodorous pests is preferably 0.01 to 3% by weight. Within such a range, an appropriate insecticidal effect can be exerted against malodorous pests. If the content of the insecticidal component in the composition for controlling malodorous pests is less than 0.01% by weight, the insecticidal component may be insufficient and the insecticidal effect may be insufficient. On the other hand, if the content of the insecticidal component in the malodorous pest control composition exceeds 3% by weight, the concentration of the insecticidal component becomes high, so that it may be difficult to properly prepare the malodorous pest control composition.

<Deodorant method, foul odor pest control method>
