preparation example Construction

[0078] Examples of solvents used in the preparation of flying pest repellent products include lower alcohols such as water, ethanol, and isopropanol; ketone solvents, ester solvents, and hydrocarbon solvents such as n-alkane and isoalkane. Examples of surfactants include polyoxyethylene hydrogenated castor oil, polyoxyethylene higher alkyl ethers (polyoxyethylene lauryl ether, polyoxyethylene oleyl ether, etc.), polyoxyethylene alkylphenyl ethers, polyoxyethylene Oxyethylene higher fatty acid esters, polyoxyethylene sorbitan fatty acid esters, polyoxyethylene glycerin fatty acid esters, polyoxyethylene polyoxypropylene alkyl ethers and other non-ionic surfactants; laurylamine oxide, stearamide Oxide, lauryl amidopropyl dimethylamine oxide and other advanced alkyl amine oxide-based surfactants, etc. These surfactants may be used alone or in any combination.

Embodiment 1

[0087] The flying pest repelling fragrance composition of the present invention was prepared as follows: 8.0% by mass of p-tert-butylcyclohexyl acetate and 3.2% by mass of phenylethyl acetate were blended as the (a) component of the flying pest repelling fragrance components, namely Acetate compound represented by general formula (I); 14.3% by mass of terpineol, 9.8% by mass of geraniol, and 12.0% by mass of dihydromyrcenol as (b) in the flying pest repelling fragrance ingredient Components are monoterpene alcohols and / or aromatic alcohols with 10 carbon atoms, and 38.0 mass % of dipropylene glycol is used as a repelling effect continuous component, and then other flying pest repelling fragrances (containing 7.1 mass % of phenylethyl alcohol) of 14.7 mass % are combined. and 1.6% by mass of cinnamyl formate). The compounding ratio of (a) component in the said flying pest repellent fragrance composition with respect to (b) component was 0.32 times.

Embodiment 1

[0091] Comparative Example 1, mixing 12 mg of styrenyl acetate as the (a) component in the fragrance composition of flying pest repellent is the acetate compound represented by general formula (I); The component (b) is a monoterpene alcohol and / or an aromatic alcohol having 10 carbon atoms, and each repelling effect sustained component is blended into the mixture to prepare a flying pest repelling fragrance that can be used in the flying pest repelling product of the present invention. combination. The durability evaluation test 1 demonstrated below was implemented about the obtained flying pest repellent fragrance composition. In this test, the repellent activity against adults of Culex acutinae (♀) was used as an index for the evaluation of persistence.

[0092] Filter paper with a diameter of 15 cm was impregnated with 0.5 mL of an acetone solution containing 70 mg of the above-mentioned flying pest repellent fragrance and 70 mg of each repellent-lasting component, and the...

Abstract

Provided are a flying-insect pest repellent product having excellent repelling effect on flying insect pests while utilizing characteristics of silicone rubber, and a method for repelling flying insect pests. In the flying-insect pest repellent product of the present invention, obtained by retaining a flying-insect pest repellent fragrance composition containing a flying-insect pest repellent fragrance component on a rubber molded article containing silicone rubber and having a hardness of 50 or less, the rubber molded article is an annular rubber molded article provided with an expandable annular part into which a part of the human body or an object is inserted or fitted, and the flying-insect pest repellent fragrance component is volatilized for 5-15 hours from a surface of the annular rubber molded article in a state in which a part of the human body or an object is inserted or fitted in the annular part.

Description

technical field [0001] The invention relates to a product for repelling flying pests and a method for repelling flying pests. Background technique [0002] Conventionally, a method of applying a repellent containing DEET (N,N-diethyltoluamide) to the skin surface has been widely used against flying pests such as mosquitoes, gnats, midges, and flies. However, since DEET has slightly lower volatility than general fragrance ingredients, it cannot expect a spatial repellent effect. On the other hand, although normal-temperature volatile insecticidal components, such as pyrethroid-based Yibangning, can be volatilized in space to achieve the repelling effect on flying pests, there are many normal-temperature volatile insecticidal components. The use of is to be kept at arm's length. [0003] Therefore, several attempts to use volatile natural essential oils and their constituents as repellent ingredients have been proposed. For example, citronella oil and its main component, ci...
