Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention eliminates fungal odors such as musty odors generated under kitchen sinks, storage cases, wash basins, closets, basements, storage rooms, shoe boxes, bathroom walls, floors, and under floors. The present invention relates to a deodorant for odorous fungal odors and a deodorizing method therefor, a growth inhibitor for fungi such as mold and a growth inhibiting method therefor, and an insect repellent and an insect repellent method.

[0002]

2. Description of the Related Art In Japan, which has high humidity and high humidity, it is a climate in which fungi and other fungi easily grow in the living space, and the generation of offensive odor due to mold causes a problem. In addition, the increase in the number of highly sealed houses such as condominiums has become a problem not only during the rainy season but also throughout the year. In particular, the sources are walls, floors, such as storage compartments, under the washbasins, closets, basements, storage rooms, and shoeboxes.

The off-flavor of mold is caused by 2-methylisoborneol (detection threshold value 0.03 ppb), geosmin (detection threshold value 0.2 ppb) and the like, which are neutral alcohol substances having very low threshold values. As a method for deodorizing these odors, a method using a general deodorant based on a neutralization / addition reaction (a compound having a carboxyl group, an amino group, polyphenol, a compound having a conjugated double bond, etc.) can be considered. However, it cannot be expected to be effective because the musty odor substance is a neutral alcohol substance.

Although it is possible to use the above deodorant in a large excess, when the solvent of the deodorant is water, there is a risk that the sprayed water may further increase the humidity and cause mold growth. Also, in the case of an organic solvent, there is a risk of discoloration on the wall surface, stored items, and the like. There is also a method of physically adsorbing using activated carbon, etc., but this also requires a large amount of air to be sucked and circulated in order to sensibly reduce the low threshold odor, and the equipment becomes large and running cost and A great deal of cost is required for filter replacement and the like.

There is also a method of sterilizing the growing mold by using a commercially available synthetic fungicide (BIOZOL 3-methyl-4-isopropylphenol, PCMX), but this also requires a large amount of the fungicide to be sprayed. Similarly, there is a concern that the solvent may increase the humidity or discolor. Hypochlorous acid and sodium isocyanurate, which are also strong antifungal agents, are not preferable because of safety problems such as suction during spraying.

[0006]

SUMMARY OF THE INVENTION Therefore, it is a first object of the present invention to provide a deodorant for fungal odors such as musty odor and a deodorizing method thereof, which is safe without being sprayed in a large amount. To do.

[0007] Further, since the same problems also occur with fungal growth inhibitors such as mold, the present invention provides a safe fungal growth inhibitor for molds and the like and a method for inhibiting the growth thereof, without spraying in a large amount. The second purpose is to provide

[0008]

Means for Solving the Problems In order to achieve the above first object, the present inventor has conducted extensive studies and as a result, the surfactant is useful for deodorizing fungal odors such as mold odor. I found that. That is, the present invention is a fungal odor deodorant containing a surfactant as an active ingredient, and a fungal odor deodorant method in which the fungal odor is deodorized by dispersing the surfactant.

Since the deodorant for fungal odor and the method for deodorizing the same according to the present invention can disperse the surfactant efficiently to deodorize the fungal odor, a large amount of the deodorant can be applied. There is nothing to do. Further, since the surfactant is safe, it can be used without problems in ordinary households.

In order to achieve the second object, the present inventor has conducted extensive studies and found that a surfactant is useful for suppressing the growth of fungi such as mold. That is, the present invention is a method for suppressing the growth of fungi, which contains a surfactant as an active ingredient, and a method for suppressing the growth of fungi, which suppresses the growth of fungi by dispersing the surfactant.

Since the fungal growth inhibitor and the method for inhibiting the growth thereof according to the present invention can effectively suppress the growth of the fungus by dispersing the surfactant, it is necessary to spray a large amount of the growth inhibitor. There is no. Further, since the surfactant is safe, it can be used without problems in ordinary households.

Furthermore, the present inventor has found that the surfactant has an insect repellent effect in the research for achieving the first and second objects. That is, the present invention is an insect repellent containing a surfactant as an active ingredient.
