Description

The present invention relates to an indoor dust mite repellent and an indoor dust mite repellent article using the same.

A great variety of mites live on the earth. For example, citrus mites and nymph mites parasitizing plants cause great damage to crops. Acaricides aimed at controlling mites parasitic on these plants have been developed for a long time, and promising new compounds have been discovered one after another.
On the other hand, due to changes in the living environment in recent years, indoor dust mites such as mites, leopard mites, and dust mites are generated indoors, causing problems such as causing allergic asthma and skin rash as well as discomfort. ing.
Therefore, there has been a demand for an indoor acaricide for treating carpets, bedding, etc., but a useful acaricide against mites parasitic on plants is not necessarily effective against indoor dust mites. There was a situation. This is thought to be due to species differences in which mites parasitizing plants mainly belong to the anterior genus, while dust mites that live indoors mainly belong to the aerial genus. Also, because there are many use cases that directly contact the skin indoors, it is necessary to develop a safer drug. Further, leopard mites that cause allergic asthma can cause allergies even in the corpse of the worm body itself. It has become clear.

Against this background, a technique for preventing tick from approaching people and patients rather than killing indoor dust mites has been sought, and several proposals have been made so far. For example, JP-A-3-264504 discloses an acaricide or a tick repellent containing eugenol, n-hexyl benzoate or the like as an active ingredient. JP-A-6-16515 discloses plant essential oils such as vetiver oil, patchouli oil, and clove oil as active ingredients for indoor mite control agents, and JP-A-2001-31508 discloses 1,8- Although cineole or eucalyptus oil containing a large amount of this component is disclosed and consideration is given to natural product orientation and safety, the repellent effect on indoor dust mites is not satisfactory.
By the way, the applicant of the present application previously mentioned cinnamyl acetate, methyl cinnamate and the like (Japanese Patent Laid-Open No. 3-81202), heliotropin and anisaldehyde (Japanese Patent Laid-Open No. No. 123714) was disclosed, but at that time it was intended to be an acaricide, so there was room for improvement in the spirit of the present invention.
Furthermore, as a method for removing mite allergens, for example, methods using components such as benzalkonium chloride and sesquiterpene alcohol have been proposed (JP 2001-335474 A and JP 2003-238394 A, respectively). . However, the application of these allergen reducing agents does not provide an allergen-reducing effect and does not have an action to keep ticks away, so that a practical clean environment cannot be created.
JP-A-3-264504 Japanese Patent Laid-Open No. 6-16515 JP 2001-31508 A JP-A-3-81202 Japanese Patent Laid-Open No. 3-90004 Japanese Patent Laid-Open No. 3-123714 JP 2001-335474 A JP 2003-238394 A

Since the present invention is highly safe for human livestock, it can be safely applied to living rooms, carpets, bedding, tatami mats, floors, etc., and the volatilization action of the repellent component, or the volatilization action and contact action thereof, An object of the present invention is to provide an indoor dust mite repellent that exhibits an excellent repellent effect on clams and the like, and an indoor dust mite repellent article using the same.

In order to achieve the above object, the present invention adopts the following configuration.
(1) As a repellent component, it contains (a) cinnamic acid analogs, (b) benzaldehydes and / or eugenols, and a weight ratio of (a) :( b) is 1: 0.2 to 1: An indoor dusty mite repellent that is 3.0.

(4) An indoor dusty mite repellent according to any one of (1) to (3), comprising 0.5 to 10% by weight of the repellent component relative to the total amount and supported on a liquid carrier or a gel carrier Agent.
(5) An indoor dust mite repellent which is an article containing the indoor dust mite repellent according to (4) contained in a container having a volatilization means and which repels indoor dust mites by the volatilization action of the repellent component. Goods.
(6) An article in which the indoor dust mite repellent according to (4) is filled in an aerosol sprayer together with a pump sprayer or a propellant, and by the volatilization action and contact action of the repellent component sprayed in a mist form An indoor dust mite repellent article that repels indoor dust mites.
(7) An article obtained by impregnating a non-woven cleaning sheet with the indoor dusty mite repellent according to (4), wherein the repellent component in the sheet or the repellent component transferred to the contact surface with the sheet with cleaning An indoor dust mite repellent article that repels indoor dust mites by the volatilization action and contact action.
(8) The indoor dust mite repellent article according to (6) or (7), wherein the indoor dust mite repellent contains a mite allergen reducing agent.

The indoor dust mite repellent of the present invention and the indoor dust mite repellent article using the same use two kinds of repellent components that are safe and excellent in volatility, and have excellent synergistic repellent effect. It is extremely practical.

The fact that (a) cinnamic acid analog used as a repellent component in the present invention is effective as a miticide for indoor dust mites such as mites, leopard mites, dust mites, and mites, is disclosed in JP-A-3-81202. On the other hand, (b) benzaldehydes and / or eugenols such as heliotropin and anisaldehyde are also known as acaricides.
However, the indoor acaricides described in these publications are based on the acaricidal effect mainly due to the contact action of the active ingredients, and thus have limited preparations and application methods and have not been put into practical use.
On the other hand, in the present invention, from the viewpoint of preventing indoor dust mites from being killed and keeping ticks away from humans and patients, (a) cinnamic acid analogs, (b) benzaldehydes and / or With regard to eugenols, paying attention to their volatility, we newly studied the repellent effect against indoor dust mites including volatilization action, and combined (a) and (b) within a specific range, It has been found that a repellent effect on mites is synergistically increased and an indoor dusty mite repellent excellent in practicality can be obtained.

(A) Cinnamic acid analogs are selected from, for example, cinnamyl acetate, cinnamyl formate, methyl cinnamate, ethyl cinnamate, methyl p-methyl cinnamate, cinnamaldehyde, α-hexyl cinnamaldehyde, and cinnamon oil Among these compounds, cinnamyl acetate, cinnamaldehyde, or cinnamon oil is preferable.
On the other hand, examples of (b) benzaldehydes and / or eugenols include heliotropin, p-anisaldehyde, m-anisaldehyde, perilaldehyde, eugenol, isoeugenol, dihydroeugenol, and eugenyl acetate. It is not limited to these.

The present invention is characterized in that an indoor dust mite repellent was prepared by specifying the weight ratio of (a) :( b) in the range of 1: 0.2 to 1: 3.0.
The repellent component in which (a) and (b) are combined exhibits a particularly synergistic effect within this range for both the volatilization effect and the contact effect, and an improvement in the repellent effect is recognized when outside this range. I can't.
It should be noted that when geometrical isomers and optical isomers are present in the compounds (a) and (b), it is a matter of course that each of them and any mixture thereof are also included in the present invention.

The indoor dust mite repellent of the present invention is not limited to (a) cinnamic acid analogs and (b) benzaldehydes and / or eugenols, as long as they do not hinder safety and repellent efficacy. Terpene-based repellent components such as menthol, citronellol, terpineol, α-pinene, geraniol, camphor, linalool, caran-3,4-diol, or eucalyptus, citronella, neem, lavender, lemongrass, clover, bergamot, etc. Essential oils, extracts, salicylic acid esters, benzyl alcohol esters, jasmonic acid esters and the like may be added.
Furthermore, it is also possible to make a multipurpose composition by appropriately blending other kinds of active ingredients such as insecticides, bactericides, fungicides, and deodorants.

The indoor dusty mite repellent of the present invention may be composed of only the repellent component, but usually a suitable solution and other additives are added to the repellent component to form a liquid agent (here, the liquid agent is water-soluble, This refers to liquid preparations in the form of emulsions or suspensions, including emulsions, wettable powders, oils, flowables, aqueous solvents, etc.), gels, solids, sheets, etc. .
Among these, the form which contains 0.5-10 weight% of repellent ingredients with respect to the whole quantity, and is made to carry | support on a liquid support | carrier or a gel-like support | carrier is typical.

Examples of the liquid carrier used include water, alcohols (ethanol, isopropanol, etc.), polyhydric alcohols (diethylene glycol, propylene glycol, 1,3-butylene glycol, glycerin, etc.), ketones (acetone, methyl ethyl ketone, cyclohexanone). Etc.), ethers (ethyl ether, dioxane, diethylene glycol monobutyl ether, propylene glycol monomethyl ether, etc.), aliphatic hydrocarbons (kerosene, mineral oil, kerosene, etc.), aromatic hydrocarbons (xylene, methylnaphthalene, etc.), Solvents such as esters, acid amides, and nitriles are suitable, and one or a mixture of two or more of these is used.
Among them, ethanol is excellent in quick-drying, so a solution containing ethanol as a main solvent is suitable for the treatment of carpets and bedding, and further includes safety against fire, and contains cationic surfactants or anionic surfactants. When considering the formulation of the mite allergen reducing agent to be used, a mixed solvent of ethanol and water (for example, ethanol / water = 50/50 to 60/40) is more preferable.

Examples of the gel carrier include carrageenan, xanthan gum, gellan gum, gelatin, aluminum octylate, and 12-hydroxystearic acid.
Examples of the solid carrier include inorganic porous carriers such as clays (kaolin, bentonite, etc.), talcs, silicas, alumina powder, activated carbon, cellulose carriers such as pulp, linter, rayon, trioxane, Examples include sublimable carriers such as adamantane, and if necessary, impregnating components can be impregnated with a solvent or the like to prepare indoor dusty mite repellents such as solid, sheet and granular.

Furthermore, in the indoor dusty mite repellent of the present invention, additives such as surfactants, dispersants, spreading agents, penetrants, stabilizers, pH adjusters, colorants, etc. may be used as appropriate. When the cyclic silicone is added in an amount of about 1 to 8% by weight, preferably about 3 to 6% by weight based on the total amount, it is useful for protecting the fibrous body when it is processed on a carpet or bedding.
Moreover, as a propellant used when preparing aerosol, dimethyl ether, liquefied petroleum gas, Freon gas, compressed gas (nitrogen, carbon dioxide gas, etc.) is mention | raise | lifted.

The indoor dust mite repellent of the present invention preferably contains a mite allergen reducing agent such as a cationic surfactant, an anionic surfactant or sesquiterpene alcohol. That is, while the live mites are kept away from the target area, the allergen activity is reduced for the remaining dead mites and mite feces and the like, and a clean environment free from mite allergens can be efficiently provided.
Cationic surfactants include dilong chain alkyldishort chain alkyl quaternary ammonium salts (distearyldimethylammonium salt, distearylmethylhydroxyethylammonium salt, dioleyldimethylammonium salt, etc.), monolong chain alkyltrishort chain Examples include alkyl type quaternary ammonium salts (such as lauryl trimethyl ammonium salt and stearyl dimethyl benzyl ammonium salt) and tri long chain alkyl mono short chain alkyl type quaternary ammonium salts (such as trilauryl methyl ammonium chloride and tristearyl methyl ammonium chloride). . In addition, the mixing | blending of a suitable quantity cationic surfactant also has the merit that a softness | flexibility can be provided to a process fiber body.
On the other hand, examples of anionic surfactants include lauryl benzene sulfonate, lauryl sulfate, lauryl sulfate triethanolamine, and polyoxyethylene lauryl ether sulfate. An agent may be configured.
The blending amount of the mite allergen reducing agent is suitably 0.2 to 10% by weight, and excessive application is not preferable because it may impair the feel of the fibrous body.

The amount of active ingredient in the indoor dust mite repellent of the present invention and the amount of use thereof are appropriately determined according to the dosage form, application object, application method, application location, and the like. For example, when targeting leopard mites that live on carpets, bedding, etc., (a) cinnamic acid analogs, and (b) benzaldehydes and / or eugenols are combined in amounts (a) and (b). May be set to 1.0 mg or more per 1 m ² , preferably 10 mg to 1000 mg.

The indoor dusty mite repellent of the present invention thus obtained has high safety against human livestock, so it can be safely applied to living rooms, carpets, bedding, tatami mats, floors, etc., and mite, leopard mites, dust mites, claw mites, etc. Has an excellent repellent effect. Therefore, it does not come into contact with indoor mites that cause allergies, and if a mite allergen reducing agent is added, allergen activity caused by dead mites and mite feces can be suppressed, so it can be used as a substitute for acaricides. As such, its practicality is extremely high.
Next, main indoor dust mite repellent articles to which the indoor dust mite repellent of the present invention is applied will be described in detail, but of course not limited thereto.

As a first use form, an indoor dust mite repellent in which a repellent component is supported on a liquid carrier or a gel carrier is housed in a container having a volatilization means, and the indoor dust mite is repelled by the volatilization action of the repellent component Examples include dust mite repellent articles.
As a volatilization means, a liquid absorption core type that has a liquid absorption core that sucks up the mite repellent of an aqueous liquid preparation and an evaporation section that is located above the liquid absorption core and dissipates the aqueous liquid preparation that has been sucked up, The gel type which volatilizes a body through the cover material which has a volatilization hole can be illustrated, and it is also possible to charge a container with artificial flowers etc. and to improve interior property.

A preferable aqueous liquid formulation in the liquid-absorbent core type contains 0.5 to 10% by weight of the repellent component, 1.0 to 15% by weight of the surfactant, 2.0 to 10% by weight of the lower alcohol, and water. The surfactant is preferably a combination of a higher alkylamine oxide surfactant and a nonionic surfactant in view of the stability and releasability of the repellent 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 1.0% by weight, solubilization of the repellent component is poor, and if it exceeds 15% by weight, the dispersibility of the repellent component may be affected.
Moreover, as a lower alcohol, ethanol or isopropanol is typical, and ethanol is preferable in terms of performance. When the blending amount of the lower alcohol is less than 2.0% by weight, the compatibility with the repellent components is inferior. On the other hand, when the blending amount exceeds 10% by weight, the danger to fire increases and it does not fall under the category of non-dangerous substances in the Fire Service Act Will occur.

The second form of use is that the indoor dusty mite repellent with a repellent component carried on a liquid carrier is filled in an aerosol sprayer together with a pump sprayer or a propellant, and the volatilization action of the repellent component sprayed in a mist form and An indoor dust mite repellent article that repels indoor dust mites by contact action.
Here, as in the case of the liquid absorption core type of the first use form, the indoor dust mite repellent is preferably an aqueous liquid agent, and a prescription according thereto can be adopted, but treatment of carpets, bedding, etc. It is better to formulate ethanol having excellent quick drying properties as a main solvent.
If 0.2 to 10% by weight of a mite allergen reducing agent such as a cationic surfactant, an anionic surfactant or sesquiterpene alcohol is added, in addition to keeping ticks away, dead mites and tick feces It is more preferable because the allergen activity caused by can be suppressed.
Further, there are various types of pump type sprayers such as a direct pressure type or a pressure accumulation type, but the shape is not limited at all.

The indoor dust mite repellent article of the third usage form is made by impregnating a nonwoven fabric cleaning sheet with an indoor dust mite repellent having a repellent component carried on a liquid carrier, and this repellent component in the sheet or this cleaning accompanies this cleaning. It is intended to repel indoor dust mites by the volatilization action and contact action of the repellent component transferred to the contact surface with the sheet. In addition, the indoor dust mite repellent article of the present invention is a dry type considering the feeling of use, and the amount of impregnation of the repellent to the cleaning sheet is suitably set to about 0.5 to 20% by weight. .
Here, the nonwoven fabric cleaning sheet is a sheet obtained by laminating or entanglement of fiber assemblies such as rayon, polyolefin, polyester, etc., and using this to wipe tatami mats, floors, furniture, etc., voids in the fiber assembly Garbage and dust are trapped. For this reason, the liquid formulation impregnated into the sheet preferably contains surfactants, mineral oil, silicone oil, etc. in addition to repellent components, from the viewpoint of trapping dust and dirt, and further reduces mite allergens as described above. A blending agent is more preferable.
There are some wet-type cleaning sheets on the market that remove mite allergens and deodorize and disinfect them, but they do not have a repellent action against mites. On the other hand, the indoor dusty mite repellent article of the present invention is characterized by volatilizing action of the repellent component and tick repellent by contact action, and has the merit that it is easy to use because it is a dry type.

As described above, the indoor dust mite repellent of the present invention can be applied to various indoor dust mite repellent articles, and is extremely useful as a measure for keeping away mites such as living rooms, carpets, bedding, tatami mats and floors. is there.
Next, based on a concrete Example, the indoor dusty mite repellent of this invention and the article for indoor dusty mite repellent using the same are demonstrated in detail.

FIG. 1 shows a cross-sectional view of one usage pattern of the indoor dusty mite repellent article of the present invention.
Cinnamyl acetate 1.2% by weight as repellent component, cinnamaldehyde 0.7% by weight, dihydroeugenol 1.0% by weight, laurylamine oxide 1.2% by weight as surfactant, polyoxyethylene hydrogenated castor oil 6 wt%, polyoxyethylene oleyl ether 3.0 wt%, ethanol 7.0 wt%, green tea extract component 1.0 wt% as deodorant, citric acid 0.02 wt%, and purified water 83.28 An indoor dusty mite repellent 1 according to the present invention containing% by weight was prepared. This water repellent was classified as a non-hazardous material under the Fire Service Act.

A disc-like felt evaporation part 6 having a thickness of 5 mm and a diameter of 5.2 cm, which is installed on the evaporation part support 5, was attached to the top surface of the liquid absorbent core 3. Further, a plastic artificial flower 7 having an apparent volume of 320 cm ³ and imitating cattleya was loaded through the evaporating part support 5 thereabove to produce a stationary indoor dust mite repellent article.
When this tick repellent article was placed on the side board of the bedroom and used, the repellent component was volatilized through the liquid absorbent core 3 and the evaporating part 6 for about one month. It was possible to prevent entry from outside. In addition, there was a sense of fragrance in the bedroom, and Cattleya was excellent in interior.

Methyl cinnamate 1.5% by weight, cinnamic aldehyde 0.4% by weight, heliotropin 0.8% by weight, anionic surfactant (polyoxyethylene lauryl ether sulfate) and phenolic polymer as repellent ingredients The contained mite allergen reducing agent 2.0 is dissolved in 100 mL of an aqueous ethanol solution (ethanol / water = 55/45) and filled in a pressure-accumulating pump sprayer with a trigger for spray-type indoor dust mite repellent. Articles were prepared.
When about 20 mL of this tick repellent article was sprayed onto a bedroom futon, the leopard mites in the futon escaped by the volatilization action and contact action of the repellent component, and no leopard mites were observed at one week after observation. . Moreover, the mite allergen reducing agent can suppress the mite allergen activity due to dead mites and mite feces, and can create a clean environment free from tick allergens.

Cinnamyl acetate as a repellent component 3.0% by weight, m-anisaldehyde 1.4% by weight, nonionic surfactant (polyoxyethylene oleyl ether) 0.9% by weight, silicone oil 1.2% by weight, An indoor dusty mite repellent of the present invention was prepared by dissolving 1.8% by weight of a mite allergen reducing agent containing a cationic surfactant (distearyldimethylammonium salt) and sesquiterpene alcohol in mineral oil.
A non-woven fabric cleaning sheet (weight per unit: 60 g / m ² ) obtained by entanglement lamination of rayon fiber assembly on both sides of the polyester fiber assembly layer is impregnated with 1.5% by weight of the mite repellent per cleaning sheet. Then, a dry type indoor dust mite repellent article was produced in the form of a nonwoven fabric cleaning sheet.
This cleaning sheet was wound around a cleaning plate of a floor-use cleaning tool and used for cleaning the flooring floor. As a result, the volatilization action and contact action of the repellent components in the cleaning sheet, and the volatilization action and contact action of the repellent components transferred to the contact surface with the cleaning sheet as a result of the cleaning, the indoor dust mites on the cleaning surface. It was possible to give the effect of not approaching. In addition, the mite repellent article of the present invention is extremely practical because it spreads aroma during cleaning, has excellent dust and dust trapping properties, and can also suppress mite allergen activity due to dead mites and mite feces. there were.

According to Example 2, various indoor dust mite repellents (solvent: ethanol aqueous solution) shown in Table 1 were prepared, and the following repellent efficacy test was performed.
[Repellent efficacy test]
A petri dish having a diameter of 9 cm was fixed on the pressure-sensitive adhesive sheet, and about 10,000 individual leopard mites or prickly tick were released in the petri dish together with the medium. Next, a drug-treated carpet having a diameter of 4 cm (treated with a predetermined amount of drug on an untreated carpet and then air-dried for 2 hours) was fitted in a petri dish having a diameter of 4 cm, and 50 mg of a reference medium was placed in the center. This petri dish with a diameter of 4 cm was placed in the center of the petri dish with a diameter of 9 cm and stored under dark conditions at 25 ° C. and 75% RH. Similarly, it was set as the no-treatment section using the carpet which does not perform a chemical | medical agent process. The number of mite individuals that entered the central carpet after 24 hours was counted, and the repelling rate was calculated according to the following formula.
Repellent rate (%) = [number of invading ticks in untreated area-number of invading ticks in treated area] / number of invading ticks in untreated area
× 100

As a result of the test, the indoor dusty mite repellent of the present invention has a high synergistic effect with (a) cinnamic acid analogs, and (b) benzaldehydes and / or eugenols, and is high for both the leopard mite and the red mite. It showed a repellent effect and there was no problem in terms of smell. It should be noted that the combination of mite allergen reducing agents containing cationic surfactants or anionic surfactants is useful in terms of suppressing mite allergen activity due to dead mites and mite feces, and improving repellent efficacy. Was recognized.
On the other hand, as shown in Comparative Examples 1 to 4 and Comparative Examples 7 to 8, (a) cinnamic acid analogs and (b) benzaldehydes and / or eugenols alone had a poor repellent effect. Also, as in Comparative Example 5, when the blending amount of (b) is less than 0.2 times the amount of (a), or conversely, exceeding 3.0 times the amount as in Comparative Example 6, it is almost mixed. No synergistic effect was obtained.
Furthermore, the sesquiterpene alcohol (Comparative Example 9) proposed as a mite allergen reducing agent has a low repellent effect, and it was considered difficult to comprehensively solve the mite allergen problem only by applying the mite allergen reducing agent. .
