Description

  The present invention relates to an attractant inhibitor for indoor ticks that has a high attraction-inhibiting effect against an attracting volatile component emitted from mite baits present in indoor dust, an attraction-inhibiting method using the same, and the above-mentioned indoor tick-inducing component. The present invention also relates to a method for reducing the amount of washing and a laundry finish containing the attraction inhibitor.

  In recent years, we have been living in comfortable temperature and humidity spaces all year round for the spread of airtight houses and air conditioning. This environment is very easy for indoor dust mites living in indoor dust and dust, such as indoor carpets, tatami mats, futons, pillows, blankets, sofas, stuffed animals, and vehicle seats. I can say that.

  In addition to this favorable condition, if there are human secretions such as dirt, sebum, dandruff, sweat, hair, saliva, etc., or food waste such as food spills, etc. It is expected to lead to abnormal growth of house dust, mite mites, and claw mites that prey on these mites, indoor dust such as futons, pillows, blankets, sofas, stuffed toys, and vehicle seats. Further, dust mites, such as mite mites and mushroom mites, are particularly problematic because their mites themselves and dead bodies are said to cause allergic diseases such as bronchial asthma and allergic rhinitis and dermatitis.

  Conventionally, as a method of reducing the amount of these indoor mites, (1) a method of killing or repelling a tick by using a miticide or repellent at a place where mites live, (2) a method of attracting and physically removing mites themselves (3) A method of physically sucking allergens generated from tick feces or dead bodies with a vacuum cleaner or the like has been known.

For example, (1) pyrethroid insecticides, benzyl benzoate and the like are known as acaricides, and DEET (N, N-diethyltoluamide) is known as a repellent.
(2) The method of physically removing using an attractant is a fatty acid ester having 14 to 18 carbon atoms (Patent Document 1), food flavor, food flavor and triglyceride, linear fatty acid having 4 to 18 carbon atoms (Patent Document) A method using an attractant such as 2) has been proposed.
In addition, (3) among the physical removal methods of mite allergens using a vacuum cleaner, as an aid for increasing the removal efficiency, salt; bactericides; powdered compositions for indoor treatment consisting of fragrances and dietary attractants A method of sowing in advance has been proposed.

  However, when an acaricide is used, there are problems with the safety of drugs themselves remaining on tatami mats, carpets, futons, etc., and allergen problems caused by mite carcasses. Also, when using repellents or physically exterminating with attractants or specific cleaning aids, the range of effects is limited for thick materials such as carpets and futons with long hairs. There's a problem.

  Non-Patent Document 1 discloses data showing butyric acid, ethyl acetate, ethyl isovalerate, and the like that have an attractive force against acarid mites. Patent Document 1 includes fatty acid esters having 14 to 18 carbon atoms (methyl myristate, methyl oleate, etc.); Patent Document 2 includes linear fatty acids having 4 to 18 carbon atoms; Patent Document 3 includes cheese flavor and butter flavor ( It is disclosed that (which contains a large amount of lower fatty acids such as butyric acid, normal valeric acid, and isovaleric acid) has an excellent attracting effect on mites such as leopard mites and mites.

  Patent Document 4 discloses an adjustment method in which a solute and a solvent are brought into direct contact to weaken the odor intensity of the solute, and the odor intensity of isovaleric acid containing a solvent having an SP value of 18.1 to 38.1 is disclosed. Odor modifier that reduces the odor, odor modifier that reduces the odor intensity of limonene containing a solvent having an SP value of 13.9 to 33.9, and trans-2 containing a solvent having an SP value of 16.2 to 28.2 An odor modifier that reduces the strength of the odor of Nonenal is disclosed.

  The present invention is a safe and less burdensome to the cleaner, a new indoor mite attraction inhibitor that suppresses the accumulation and proliferation of ticks, an indoor tick attraction suppression method, a method for reducing indoor mite attraction components, and Provide laundry finish.

  As a result of examining a new method for suppressing the attracting property of mites emitted from human body secretions, food waste, cosmetics or cosmetics in a safer manner, the present inventors have found that human secretions that mites feed on mites ( The present inventors have come up with a method of reducing the chance of contact with food waste, cosmetics or cosmetics (hereinafter sometimes referred to as human secretions). Specifically, by suppressing the attractiveness of the attracting component using a specific substance against the mite attracting component emitted from human secretions, food waste, cosmetics or components in cosmetics, It is an agent and a method that reduce the chances of ingesting food, and thus leads to suppression of mite growth, and further a method of reducing mite-inducing volatile components using the specific substance.

  In addition, the present inventors have newly found that linear aliphatic aldehydes and limonene emitted from human secretions, food wastes, cosmetics or textile products to which cosmetics are attached have excellent tick attracting properties. . Based on this new knowledge, the present inventors deodorize linear aliphatic aldehydes, particularly linear aliphatic aldehydes having 7 to 10 carbon atoms, and limonene, and effectively suppress volatilization of these components. As a result, it was studied to reduce and / or suppress mite attraction, and a tick attraction inhibitor was obtained.

  In addition, the present inventors have newly discovered that lactones having 4 to 14 carbon atoms have an excellent tick-inducing effect. Based on this finding, we studied to reduce and / or suppress mite attraction by deodorizing lactones having 4 to 14 carbon atoms using specific substances and suppressing volatilization etc. An inhibitor was obtained.

  Furthermore, the inventors generate tick-attracting components such as linear aliphatic aldehydes and aliphatic lactones by the oxidation of oil and fat components that are attached to textiles and the like or are present in indoor dust and become tick-inducing components. I found out. Based on the above findings, the present inventors effectively suppress the production of linear aliphatic aldehydes, aliphatic lactones, etc. in indoor dust, etc. with specific antioxidants, thereby oxidizing mite-inducing substances. In order to prevent the production of ticks, it has been studied to reduce the mite attracting property of oils and fat components present in indoor dust and to adhere to textiles and the like, and an indoor tick attracting inhibitor was obtained.

Moreover, an indoor mite attraction component can also be reduced using the 1 or more types of compound chosen from the said group.

The tick attracting inhibitor according to the present invention is a volatilization of a component that has a high tick attracting property by using a specific substance with respect to a tick attracting component generated from a component in human body secretions, food waste, cosmetics or cosmetics. By suppressing the above, it is possible to suppress tick attractiveness.
In addition, if indoor human secretions, food waste, cosmetics or cosmetics cannot be removed or cannot be removed by cleaning etc., indoor ticks such as carpets, futons, tatami etc. In particular, mites are particularly prone to proliferation, but if the secretion of mites in human secretions, food waste, cosmetics or cosmetics that serve as food is suppressed, the food is present in carpets, futons, tatami mats, etc. However, it becomes difficult for ticks to find the food, and there is less chance of contact between food and ticks. As a result, the mite proliferation can be reduced and suppressed. On the other hand, most of the tick attracting inhibitors are safer for humans than insecticides and repellents, so that mite can be controlled by a safer method.

  Furthermore, by using a specific antioxidant, the mite-inducing substance prevents the oxidation of fat components contained in human secretions, food waste, cosmetics or cosmetics that become mite foods, By suppressing the generation of these mite-attracting ingredients, it is possible to reduce the chance of contact between mites and human secretions, food waste, cosmetics or cosmetics and mites, and thus mite growth inhibition. . The indoor mite attraction inhibitor can also effectively suppress mite attraction by blending in the laundry finish.
