2. Description of the Related Art Conventionally, slime is removed from drains of sinks, bathrooms and the like by using a cleaning agent mainly containing sodium hypochlorite, sodium hydroxide, or the like, or by using isocyanuric acid (trichloroisocyanuric acid, dichloromethane, etc.). Solid tablets using a chlorine-based drug such as sodium isocyanurate), 1-bromo-3-chloro-5,5-dimethylhydantoin, and stabilized chlorine dioxide have been used. In particular, when a solid tablet using a chlorine-based drug such as isocyanuric acid is installed in a drain, the component gradually dissolves each time the drainage flows,
It has a lasting effect, unlike cleaning agents, to remove slime and dirt.

[0003] However, when these chlorine-based chemicals are used, chlorine gas is generated. Therefore, when used in a closed room, the odor may cause a bad mood due to chlorine odor. Also acids,
When the alkaline bleaching agent and the cleaning agent are erroneously applied to these agents, there is a problem that a large amount of chlorine gas is generated due to rapid reaction. In addition, there is a problem that when used in a drain port made of metal, rubber, or the like, corrosion, deterioration, and rust are generated, and a deodorizing effect of an unpleasant odor in these drain ports is not so high.

EXAMPLES Examples and comparative examples of the present invention are shown in Tables 1 and 2. However, the present invention is not limited only to the following examples. Tablets of φ35 mm × 18 mm were molded with the following composition (compounding ratio is% by weight) and various tests were performed.

[0048]

[Table 1]

[0049]

[Table 2]

1) Deodorizing test Evaluation method A petri dish in which filter paper (Advantech Toyo No. 5A 9 cm) was spread and a petri dish containing tablets were placed in a glass cylinder having a volume of 6 L, and an odorant solution (trimethylamine aqueous solution) was placed on the filter paper. Was added dropwise. Two hours after the dropping, the odor concentration in the cylinder was measured using a detector tube. Similarly, a system in which no tablets were installed was set to Blank, and the removal rate of odorous substances was calculated by the following formula.

[0051]

(Equation 1)

2) Oil Stain Test Evaluation Method A test agent (tablets stored in an open container) is actually installed and used at a kitchen drain (floor bottom surface after washing) of a family of 4 to 5 families. Ten days later, the degree of adhesion of dirt such as oil around the bottom surface of the strainer was evaluated. In addition, the evaluation was compared with the situation in which the test agent was not used by visual observation or skin feel. Evaluation criteria ◎: Dirt is not attached, 汚 れ: Dirt is not attached much, Δ: Dirt is slightly attached, ×: Dirt is attached.

3) Slime test Evaluation method A test agent (tablets stored in an open container) was placed in the kitchen drain (a bottom surface of the strainer after washing) of a family of 4 to 5 family members and actually used. On the 10th day, the degree of adhesion of the slime around the bottom surface of the strainer was evaluated. In addition, evaluation was compared with the situation in which the test agent was not used by visual observation or skin feel. Evaluation criteria ◎: Slime was considerably suppressed, 、: Slime was suppressed, Δ: Slime was slightly suppressed, and X: Slime was severely generated.

4) Corrosion test of stainless steel Evaluation method Various tablets were crushed to prepare a liquid suspended in 1 L of tap water. An appropriate amount of this solution was taken, immersed in a 10 mm × 60 mm stainless piece to a position of about 30 mm, and stored at 40 ° C. After 30 days from the storage, the surface of the stainless steel piece was visually inspected for the degree of corrosion. Evaluation criteria ◎: no change, わ ず か: slight change, but no corrosion, Δ: slight corrosion, x: severe corrosion.

Discussion In Examples 1 to 6, by using two types of porous substrates having different average pore diameters as the substrates, the porous materials were used as the substrates as shown in Comparative Examples 1 to 4. The effectiveness of the examples was recognized in terms of both the deodorizing effect and the effect of preventing the adhesion of dirt, as compared with those which did not and those using one kind of porous body.
In particular, it was found that when a porous substrate having an average pore diameter of 10 nm or more was used, it was effective in preventing the adhesion of dirt.

In Examples 4 and 5, the disinfecting effect was improved by adding a cationic surfactant and an amphoteric surfactant. Particularly, in the slime test in actual use, the slime prevention effect on the bottom surface of the strainer was improved. The result was improved. Further, in Example 6, the addition of the higher alcohol-based solvent showed not only a good result in preventing adhesion of oil stains and the like.

Further, in Examples 1 to 6 and Comparative Examples 1 to 4, a good bactericidal effect was confirmed when various natural essential oils were used as active ingredients. In Examples 1 to 6, stainless steel was not corroded unlike the conventionally used slimming agent for chlorine-based drainage.

From the above results, it is possible to obtain a drug (active ingredient) by forming a carrier with two or more kinds of base materials having different pore diameters.
The present invention provides a safe and effective disinfectant for drains which excels in carrying capacity of a substrate, adsorbs and removes unpleasant odors, and exhibits an effect of adsorbing and washing dirt such as oil.
