Abstract

PURPOSE:To provide a mildewcide capable of adhering to the applied surface for a long period when applied to a mildewed wall, and exhibiting excellent mildewcidal effect and decoloring effect, by adding an inorganic thickener to sodium hypochlorite, thereby increasing the viscosity of the mildewcide. CONSTITUTION:Sodium hypochlorite useful as a mildewcide is added with an inorganic thickener, preferably silicon dioxide, and further preferably sodium hydroxide as a decolorant. The ratios of sodium hypochlorite, sodium hydroxide and silicon dioxide are preferably 1%:1%:5%. Since sodium hypochlorite loses its activity when brought into contact with organic materials, an inorganic material such as silicon dioxide is used as the thickener.

Description

[Detailed description of the invention] The present invention relates to a fungicide with excellent residual effectiveness.

Wall surfaces such as bathrooms, kitchens, and food factories are areas where mold is likely to grow.There is a fungicide that uses sodium hypochlorite solution to kill mold, but after use, the solution runs down the wall surface and kills the mold. The mold decolorization effect is significantly reduced. The inventors of the present invention have developed a method that does not have such drawbacks and does not reduce the fungicidal effect. That is, it is characterized by adding sodium hypochlorite and, if necessary, sodium hydroxide, and further adding silicon dioxide as a thickener.

Because of this, it is possible to make the fungicide viscous, so if it is applied to a wall surface where mold is growing, it will remain attached to the applied surface for a long time, so sodium hypochlorite can be used as a fungicide. effect, and can prevent a decrease in the dye removal effect of sodium hydroxide.

Next, an example will be explained.

Example 1 A white gel-like adhesive is obtained by mixing 1% sodium hypochlorite, 1% sodium hydroxide, and 5% silicon dioxide.

Example 2 A white gel-like adhesive is obtained by mixing 1% sodium hypochlorite, 1% sodium hydroxide, and 7% silicon dioxide.

Example 3 A white gel-like viscous agent is obtained by mixing 1 g of sodium hypochlorite, 1% of sodium hydroxide, and 10 g of silicon dioxide.

Next, the effects of the fungicide of the present invention according to Examples 1 to 3 will be shown by test examples.

Test Example A paper with test bacteria (Aspergillus, Niger ATOO62'i'5, Penicillium, Citrinusae F06352) is immersed in the mixture of Examples 1 to 3 for 5 seconds, and then placed on a PDA medium. Then, the presence or absence of growth was examined after culturing in a stone holder for 7 days.

In addition, in order to check the expiration period after dispensing, 3 days, 5 days, 7 days
After 5 days, the test bacteria adhesion test was immersed for 5 seconds and taken out, then PDA
After placing it on a medium and cultivating it in a constant temperature chamber for 7 days, we examined whether there was any growth or not, but no mold growth was observed, indicating that it has excellent residual efficacy.

In addition, since sodium hypochlorite loses its activity when it comes into contact with organic matter, an inorganic thickener such as silicon dioxide is desired as the thickener.
