Description

[Detailed description of the invention] Koda Yabuarashi The present invention relates to a fungicide composition.

In recent years, there has been an increase in the number of residences that are highly airtight, fully equipped with heating and cooling systems, and mold has grown not only in relatively humid places such as bathrooms and kitchens, but also in closets, roof bags, etc. This has become a major issue from a sanitary and aesthetic point of view.

Since there are many different types of mold that occur under normal living conditions, it is recommended as a household mold repellent.

It is necessary to be effective against mold over a wide range, but
Furthermore, it is required to maintain its effectiveness for a long time even in humid places.

However, conventional fungicides do not maintain their effectiveness over long periods of time, and their effectiveness is particularly noticeable in humid areas. It has been extremely difficult to prevent this for a long time. In addition, most commercially available fungicides use a low-boiling solvent as a diluent to dissolve the antifungal compound, and most of them are aerosol types that use a propellant, so they can be sprayed onto a surface. Since the low boiling point solvent and propellant evaporate rapidly, when used in a humid place, moisture in the atmosphere condenses and whitening occurs at the spraying site.

The present invention maintains a strong anti-fungal effect for a long period of time even in wet locations.

Spraying provides a fungicide that can sometimes prevent whitening from occurring.

The fungicide composition of the present invention is characterized by containing the following components (A) to (C).

(A) Antifungal compound = 0.1 to 5.0% by weight, (B)
Water-insoluble polyvinyl compound 2 0.1 to 5.0% by weight and (C) organic solvent represented by general formula (I) or (n):
0.1 to 20% by weight R'O(E O)X (p 0)yR" (x
) CH, OCC, H, OH(n) (wherein R'', R'', R', R', EO, PO, x and y each represent the following.

R1, R2: Hydrogen or an alkyl group having 1 to 4 carbon atoms, which may be the same or different.

R'', R4: hydrogen or methyl group, which may be the same or different, respectively EO: ethylene oxide PO: propylene oxide x: 0-3 y: 0-3, where x + y = 1-3) The invention will be explained in more detail.

The antifungal compounds of component (A) include 2-(4-thiazolyl)benzimidazole, benzalkonium chloride, polyhexamethylene biganadine hydrochloride, chlorhexidine, orthophenylphenol, alkyl(aminoethyl) Examples include glycine hydrochloride, 4-chloro-3,5-xylenol, 2,4.4'-trichloro-2'-hydroxydiphenyl ether, and these may be used alone or as a mixture of two or more.

Among these antifungal compounds, 2-(4-thiazolyl)benzimidazole is preferably used because it is highly safe and has a broad antifungal spectrum.
thiazolyl) benzimidazole and long-chain alkyldimethylbenzylammonium salt in a weight ratio of 1=9 to 9:1.
In particular, when used in a mixed ratio of 1:4 to 4:1, it is advantageous because the antifungal spectrum can be further expanded and the concentration used can be lowered.

(A) The antifungal compound may be present in the composition of the present invention from 0.1 to
It is blended in a range of 5.0% by weight, more preferably 0.2% by weight.
-3.0% by weight. If the amount is less than 0.1% by weight, the fungicidal effect will not be sufficiently expressed, while if the amount exceeds 5.0% by weight, whitening of the area will increase when spraying. It is often used in places that easily get wet with water, but by incorporating the water-insoluble polyvinyl compound as component (B), the antifungal effect can be sustained for a long time even in such cases. When a fungicide is applied to a desired location and then dried, the active ingredient will not be removed even if it gets wet because this polymeric compound is water-insoluble.

Specific examples of the water-insoluble polyvinyl compound of component (B) include polyvinyl acetate, partially saponified polyvinyl acetate, formalized polyvinyl alcohol, formalized partially saponified polyvinyl acetate, butyralized polyvinyl alcohol, and butyralized partially saponified polyvinyl acetate. Polyvinyl acetate, ethylene
Examples include saponified vinyl acetate copolymers, vinyl acetate-acrylamide copolymers, vinyl acetate-methyl vinyl ether copolymers, and saponified vinyl chloride-vinyl acetate copolymers. Unions, copolymers, saponified products thereof, and acetalized products thereof are preferred. In addition, from the viewpoint of the solvent used to make the target composition into a homogeneous solution, alcohol-soluble ones are advantageous.

These (B) water-insoluble polyvinyl compounds are contained in the composition in an amount of 0.1 to 5.0% by weight, more preferably 0.2 to 3.0% by weight.
It is blended in a range of % by weight. If this amount is less than 0.1% by weight, the antifungal effect will not last long enough;
If the amount exceeds % by weight, the gloss of the attached area will increase and the finish will deteriorate, which is not desirable).

The organic solvent represented by the following general formula (1) or (II) as component (C) has the effect of preventing whitening of the area when sprayed after use.

The organic solvent (C) component is blended in the fungicide composition of the present invention in an amount of 0.1 to 20% by weight, preferably 0.5 to 15% by weight. If the amount is less than 0.1% by weight, the anti-whitening effect will be insufficient, while if it exceeds 20% by weight, the irritating odor will become strong, which is not preferable.

The fungicide composition of the present invention is used after being diluted with a solvent, and as the solvent, an organic solvent system or a mixed system of an organic solvent and water can be used. Suitable organic solvents include lower alcohols such as methanol, ethanol, propatool and isopropanol, lower diols such as ethylene glycol and propylene glycol, and lower ketones such as acetone and methyl ethyl ketone.

Particularly suitable in terms of safety and drying properties are ethanol, propatool or isopropatool, which are optionally used in combination with water.

Miwatachihoka According to the invention, with antifungal compounds.

By using a water-insoluble polyvinyl compound and a specific organic solvent, whitening can be effectively prevented from occurring when applied, and the antifungal effect can be expressed for a long period of time even in a wet environment, making it suitable for household use. It is especially suitable for use in wet or humid places such as bathrooms.

The fungicide composition of the present invention can be used in any form such as coating, spraying, or spreading, and is particularly suitable for spraying because it effectively prevents whitening.

Example 1 0.2% by weight of 2-(4-thiazolyl)benzimidazole, 0.1% by weight of benzacornium chloride, 1.0% by weight of polyvinyl butyral, and 5% by weight of various organic solvents shown in Table 1. An aerosol-type fungicidal composition was prepared by adding Freon 12 as a propellant at a rate of 25 g/100 mQ to the ethanol solution containing the sample.

This was sprayed on the walls of the bathroom where mold tends to grow, and the whitening of the sprayed area and the anti-mold effect after a few days were evaluated based on the following criteria. The results are shown in Table-1.

Ki・ke 1 no h) ○: No whitening of the area was observed after spraying.

Δ: Slight whitening of the sprayed area is observed.
