Description

[Technical Field]

[0001] The present invention relates to a fungicide, a composition for controlling hard surface fungi, and an aerosol product for controlling hard surface fungi. [Background technology]

[0002] As living spaces in ordinary homes become more airtight, bacteria, mold, and other microorganisms are more likely to grow. Mold growth, in particular, not only causes discomfort to residents but can also lead to health problems such as allergies and infectious diseases, making it a serious hygiene issue. Furthermore, mold is one of the most hardy microorganisms, and because it spreads via air currents, methods for controlling other microorganisms cannot necessarily be applied to it.

[0003] Glycerin fatty acid esters have traditionally been used to control microorganisms such as bacteria and fungi. For example, Patent Document 1 describes that certain types of glycerin fatty acid esters have antibacterial activity against methicillin-resistant Staphylococcus aureus.

[Example]

[0050] [Confirmation test of mold control effect (anti-mold effect) (Cladosporium cladosporioides mold spores)] (Preparation of test bacterial solution) Cladosporium cladosporioides mold spores grown on PDA medium were dispersed in a Tween 80 (polyoxyethylene sorbitan monooleate) aqueous solution, which was then diluted 400-fold with 1 / 4 GP medium to prepare a test fungus solution.

[0051] (Procedure for testing to confirm mold control effect (mold prevention effect)) Twelve mL of 99.5% ethanol and 22.4 μL of the test solutions of Inventions 1 to 6 and Comparative Examples 1 and 2 prepared in Example 1 were placed in a centrifuge tube and mixed thoroughly. 600 μL of the resulting mixture was placed in a sterilized φ6 cm Petri dish, and it was confirmed that the solution spread throughout. After thoroughly drying, 20 μL of the test bacteria solution was dropped into the center of the dish. This was left to stand for 5 days in a humidified environment at 25°C, and the presence or absence of mold growth was visually confirmed. (The test was repeated four times.) The same test was also conducted except that the test solutions of Inventions 1 to 6 and Comparative Examples 1 and 2 were not added, and the presence or absence of mold growth was visually confirmed; this served as a control.

[0052] The evaluation criteria were as follows: A: no mold growth was observed; B: almost no mold growth was observed; C: some mold growth was observed but was clearly suppressed compared to the control; and D: mold growth similar to the control. The results of the mold control effect (anti-mold effect) confirmation test are shown in Table 1 together with the formulation of the test solution.

[0053] [Table 1]

[0054] As a result of the test, it was found that Inventions 1 to 6, which are fungicides containing one or more glycerin fatty acid ester compounds (A) and a fungicide compound (B), exhibit superior fungicide effects compared to Comparative Example 1, which does not contain component (B), and Comparative Example 2, which does not contain component (A). [Example]

[0055] [Example of manufacturing an aerosol product for hard surface mold control] (Production Example 1) 50 mL of the test liquid of present invention 1 [referred to as aerosol concentrate (L)] and 50 mL of liquefied petroleum gas (G) as a propellant were pressurized and filled into an aerosol container (pressure-resistant container, volume 200 mL) with a metered dose valve and a spray volume of 0.8 mL so that the volume ratio (L / G) was 50 / 50, to produce aerosol product 1 for hard surface mold control.

[0056] (Production Example 2) An aerosol product 2 for preventing mold on hard surfaces was produced in the same manner as in Production Example 1, except that the test liquid of Invention 2 was used instead of the test liquid of Invention 1.

[0057] (Production Example 3) Aerosol product 3 for preventing hard surface mold was produced in the same manner as in Production Example 1, except that the test liquid of Invention 3 was used instead of the test liquid of Invention 1.

[0058] (Production Example 4) Aerosol product 4 for preventing hard surface mold was produced in the same manner as in Production Example 1, except that the test liquid of Invention 4 was used instead of the test liquid of Invention 1.

[Example]

[0063] [Actual use test in the bathroom] (Test Example 1) Volume 3.6m 3 In a modular bathroom (1.2m wide, 1.6m deep, 1.9m high), a person stood near the center of the bathroom and sprayed aerosol product 1 for hard surface mold control four times from a height of 1.5m above the floor toward the ceiling at a slight upward angle. After 14 days, no black mold (mold) had grown on the hard surfaces of the bathroom, such as the ceiling, walls, and floor. In other words, black mold (mold) was successfully controlled for more than 14 days.

[0064] (Test Example 2) Volume 3.6m 3 In a modular bathroom (1.2m wide, 1.6m deep, 1.9m high), a person stood near the center of the bathroom and sprayed aerosol product 2 for hard surface mold control twice from a height of 1.5m above the floor, at a slight angle upwards towards the ceiling. After 14 days, no black mold (mold) had grown on the hard surfaces of the bathroom, such as the ceiling, walls, and floor. In other words, black mold (mold) was successfully controlled for more than 14 days.

[0065] (Test Example 3) Volume 3.6m 3 In a modular bathroom (1.2m wide, 1.6m deep, 1.9m high), a person stood near the center of the bathroom and sprayed hard surface mold control aerosol product 3 five times from a height of 1.5m above the floor toward the ceiling at a slight upward angle. After 14 days, no black mold (mold) had grown on the hard surfaces of the bathroom, such as the ceiling, walls, and floor. In other words, black mold (mold) was successfully controlled for more than 14 days.

[0066] (Test Example 4) Volume 3.6m 3In a modular bathroom (1.2m wide, 1.6m deep, 1.9m high), a person stood near the center of the bathroom and sprayed aerosol product 4 for hard surface mold control four times from a height of 1.5m above the floor toward the ceiling at a slight upward angle. After 14 days, no black mold (mold) had grown on the hard surfaces of the bathroom, such as the ceiling, walls, and floor. In other words, black mold (mold) was successfully controlled for more than 14 days.

[0067] (Test Example 5) Volume 3.6m 3 In a modular bathroom (1.2m wide, 1.6m deep, 1.9m high), a person stood near the center of the bathroom and sprayed aerosol product 5 for hard surface mold control four times from a height of 1.5m above the floor toward the ceiling at a slight upward angle. After 14 days, no black mold (mold) had grown on the hard surfaces of the bathroom, such as the ceiling, walls, and floor. In other words, black mold (mold) was successfully controlled for more than 14 days.

[0068] (Test Example 6) Volume 3.6m 3 In a modular bathroom (1.2m wide, 1.6m deep, 1.9m high), a person stood near the center of the bathroom and sprayed aerosol product 6 for hard surface mold control four times from a height of 1.5m above the floor toward the ceiling at a slight upward angle. After 14 days, no black mold (mold) had grown on the hard surfaces of the bathroom, such as the ceiling, walls, and floor. In other words, black mold (mold) was successfully controlled for more than 14 days. [Industrial Applicability]
