- 5 Omg each of the mite-inviting sample was placed on each end of the box-type tester in the longitudinal direction, and only the lid (4,) coated with the above-mentioned huanesylacetone was applied to the surface coated with funaresyl acetone.
- An injection needle for introduction was attached, and a Teflon® tube coming from a device for supplying air containing the above-mentioned funesylacetone was connected to the injection needle.
- a syringe needle was introduced at the innermost part on the control side to introduce air that does not contain huanesylacetone, and clean air was introduced at a rate of 1 mL per minute.
- the test equipment was placed in a constant temperature and humidity room maintained at 37 ⁇ 1 ° C and a humidity of 75 ⁇ 5% Rh, and the test section was filled with the above concentration of funaresyl acetone.
- a dani medium containing 100,000 live mites was counted through the gap between the lids, and allowed to stand for 4 hours.
- the number of mites that had invaded the mite recruitment feed in part C of the test plot and the control plot was measured. That is, the extracted feed was put in a 5 OmL Erlenmeyer flask, 2 drops of 0.5% diluted neutral detergent for dishwashing was dropped, and saturated saline solution was poured into the flask mouth for 10 minutes. After standing, the mites floating on the upper layer were counted.
- the repellent rate was calculated from the following formula and found to be 80%.
- Repellent rate (%) (1 Number of mites infested in one test plot Z Number of mites infested in control plot) X I 0 0
- the air containing 0.001 g / L of huanesylacetone had almost no odor to humans, but had a repellent effect on mites.
- Disperse phase obtained by dissolving 2 g of farnesylacetone and 10 g of polylactic acid (manufactured by Cargill, number average molecular weight 87,000, weight average molecular weight 163, 300, DZL ratio 8Z92) in dichloromethane
- a mixture of 140 OmL of an aqueous solution of Polyvier alcohol in water and 10.4 g of a surfactant (Q12S) was mixed with a continuous phase consisting of 10.4 g at 30 ° C using a propeller-type stirrer at a stirring speed of 100 rpm. Stirring was continued for 6 minutes, and then the pressure in the reactor was increased stepwise, and stirring was continued for 6 hours under reduced pressure using an aspirator to evaporate dichloromethane.
- the obtained suspension was filtered with a glass filter, washed several times with water, and freeze-dried for a whole day and night to obtain microcapsules encapsulating r-nesile acetone.
- the obtained microcapsules were substantially spherical particles having an average particle diameter of 0.4 mm, and exhibited a smooth flow like sand particles.
- the repellency of the microcapsules obtained in Example 6 against Dermatophagoides pteronyssinus was determined by a dust repellent test method (intrusion prevention method: see Test Example 1), and was found to be 99%. In this test method, a repellency of 60% or more is considered valid. Furthermore, the microcapsules obtained in Example 6 were placed in a container without a lid, and left at room temperature for 2 months or 6 months to perform a similar test.After 2 months, 99% was obtained, and after 6 months, It showed a repellency of 81%, demonstrating that it has been kept effective for a very long time.
- Example 9 30 g of the microcapsules obtained in Example 6 were mixed with 100 g of a soft acrylic resin powder (trade name: Parapet SA-N, manufactured by Kuraray Co., Ltd.), and melted at 155 ° C for 1 minute using a two-roll mixer. After mixing, the mixture was press-molded at 160 ° C. and 50 kg / cm 2 for 1 minute, and then cooled to obtain a sheet. The microcapsules were uniformly dispersed in the sheet, and no abnormalities such as smoke were observed during the molding process.
- a soft acrylic resin powder trade name: Parapet SA-N, manufactured by Kuraray Co., Ltd.
- Monodispersed silica spheres (Snow-Tex OL, manufactured by Nissan Ichigaku Kogyo Co., Ltd.) with an average particle diameter of 0.045 ⁇ m were diluted with water to obtain a slurry with a solid content of 17%.
- porous silica powder 100 g was added to a solution prepared by dissolving 10 g of butyl polyacetate and 10 g of phenylnesylacetone in 300 mL of methanol, and methanol was distilled off using a rotary evaporator to remove methanol. After stopping the operation, the rotary evaporator was further operated at 40 ° C and 20 mmHg for 1 hour, and coated with polyacetate containing phage / renesylacetone on the inside and on the surface of the silica force. A lumpy solid was prepared. This lump was taken out and pulverized, and a small amount of talc was adhered to the surface to obtain silica particles having a particle size of lmm or less and carrying funaresylacetone.
- a storage unit containing a cylindrical form of pharmanesylacetone with an inner diameter of 8 cm and a height of 5 cm, and a method for increasing the evaporation area by soaking up the pharynesylacetone contained in the storage unit
- This device has a glass cloth (means for expanding the area of the surface) placed on the wall surface.
- the bottom and the wall surface are heated to 90 ° C using a heating wire (heating means) and pi metal (temperature control means).
- the equipment was heated, and a small fan (blower means) was used to flow 5 L / min of air from the top to the bottom of the container using a small fan (blowing means).
- the method of the present invention it is possible to effectively control mites by keeping the concentration of the compound (I) in a space intended to repel mites within a specific concentration range. Further, the agent of the present invention can add a tick control effect to various articles.
- the present application is based on Japanese Patent Application No. 200-310 409 and Japanese Patent Application No. 200-344 265 filed in Japan, the contents of which are incorporated in full herein. It is.
