Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for removing dirt from, for example, a wall in a food factory, a conveyor belt on an outer wall of a tank, a filling machine, and the like, and then spraying a chemical as a foam with a foam sprayer for a long time. The present invention relates to an agent capable of imparting a bactericidal and bactericidal effect rationally with an extremely small amount by keeping the agent in a small amount.

2. Description of the Related Art In recent years, administrative environmental hygiene measures in food handling environments, including food factories, have been established and established.
Interest in sanitation in food handling environments is increasing daily. In addition, rapid economic growth has fueled labor shortages and the need for automated cleaning and disinfection in food factories has been increasing.

[0003] Normally, sterilization and disinfection in food factories include guanidines such as polyhexamethylene biguanidine hydrochloride and chlorhexidine gluconate, alcohols such as ethanol and isopropyl alcohol, hypochlorite and chlorine. Chlorine such as fluorinated isocyanurate, inverse soap, hydrogen peroxide, iodine and the like are used in the form of an aqueous solution or a mist. All of these have drawbacks such as that they must be used at a fairly high concentration and must be allowed to act for a long time in order to obtain the desired bactericidal and eradication properties. Needed to disassemble the parts. In addition, in the case of a steeply inclined surface or a vertical surface, it is often the case that difficulties in working surfaces such as mist scattering and liquid dripping are forced. A method of preventing the problem of liquid dripping or the like by increasing the viscosity of the drug has been proposed. However, in the case of a filling machine or a conveyor belt, there is a new defect that the drug does not reach the details.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a drug which solves the conventional drawbacks, allows the drug solution to act in detail, and stays for a long time to sufficiently exert a sterilizing and disinfecting effect. It is in.

[0005]

The disinfectant of the present invention can be made to act as a stable foam using a foam sprayer by adopting the following chemical composition, so that it can be used as a vertical surface or a target surface for details. Also achieved an excellent bactericidal action.

That is, the foam disinfectant for foam spray of the present invention comprises an iodophor 1 containing iodine and an iodine compound.
Anionic surfactants having a sulfonate, sulfate, ethoxysulfate, sulfosuccinate as a hydrophilic group and non-ionic fatty acid alkanolamides or alkylamine oxides One or two selected from surfactants
1 to 40% by weight, preferably 5 to 20% by weight
%; Alcohol ethers 1 to 20% by weight, preferably 3%
-15% by weight; and water for foam spraying and disinfecting.

[0007] Unlike other fungicides, iodophor, a drug component according to the present invention, is non-selective to microorganisms and has a high effect at low concentrations. Furthermore, it has little odor like chlorine type and little corrosiveness to metals. Normal,
Iodine is commercially available as an iodine-containing preparation containing 1% to 10% of effective iodine containing an alcohol, an acid, a viscosity improver, a surfactant, and the like. In the present invention, any of such commercially available iodine is used. Can be used.
In the fungicide of the present invention, the effective iodine concentration is 0.5%
It is preferable to prepare so as to be as described above.

Next, specific examples of the anionic surfactant used as a foaming agent include linear alkyl benzene sulfonate, alkane sulfonate, alkyl sulfate, polyoxyethylene alkyl ethoxy sulfate, dialkyl sulfosuccinate. And the like, wherein the hydrophobic group is an alkyl group having 8 to 18 carbon atoms,
When the counter ion of the hydrophilic group is sodium, potassium, lithium,
Those which are ammonium and alkanolamines are preferably used. As the nonionic surfactant, carbon number 1
Monoethanolamide, diethanolamide, monoisopropanolamide of 2 to 18 fatty acids, dimethylalkylamine oxide, dimethylalkylethoxyamine oxide, dihydroxyethylalkylamine oxide and the like can be mentioned.

As the alcohol ether, any compound can be used as long as it has a hydroxyl group and an ether bond in the same molecule and is compatible with water at any ratio.
The alcohol ethers improve the liquid stability of the preparation and also act as a desired foam stabilizer.
Representative examples include cellosolves (ethylene glycol monoalkyl ether), carbitols (diethylene glycol monoalkyl ether), triethylene glycol monoalkyl ether, propylene glycol monoalkyl ether, dipropylene glycol monoalkyl ether, and tripropylene glycol monoalkyl ether. Alkyl ether and the like.

The foam disinfectant of the present invention can be prepared by mixing the above components with water so as to contain the above components in the above-mentioned weight ratios. The mixing method is not particularly limited, but it is preferable to mix the blowing agent, alcohol ethers, and then iodine in this order from the viewpoint of production operation. The water used in the present invention is preferably deionized water for iodine stability. The bactericide of the present invention has a pH of 7 or less, especially 2-4.
However, it is also possible to use pH adjusters. Further, if necessary, other components such as other bactericides, fungicides, and fragrances can be added.

【Example】

Examples 1 to 6 The components shown in Table 1 below were mixed with deionized water to prepare the respective germicides of Examples 1 to 6. The numerical values indicate weight% when the whole is set to 100. The pH of each of the prepared germicides was 3 ± 0.5.

[Table 1]

(Experimental Example) The following items were tested using the fungicide of the present invention and comparative preparations shown in Table 3 below. (Iodine stability) The preparation was placed in a brown bottle and allowed to stand at 40 ° C. for one month, and the residual ratio of effective iodine was measured. (Low-temperature fluidity) The preparation was stored at 0 ° C. for 24 hours, and determined by the speed when sucking up with a 5 ml whole pipette using a pipettor. (Foamability) SKY-370S for TA foam cleaning
Foaming property was observed using [Tanabe Seiyaku Co., Ltd.]. (Bactericidal) A bactericidal test of each preparation was carried out by the surviving bacteria count method (MBC method).

The results are shown in Table 2. The components of the comparative preparations shown in Table 2 are as shown in Table 3.

The present medicament is effective when applied and sprayed as in the case of conventional disinfectants, but when sprayed as a foam using a foam sprayer, the same amount of the medicament is used 10 to 20 times that of the prior art. It has the advantage of being able to sterilize and disinfect the size of the surface, and can exert its effects evenly on vertical surfaces and fine parts.
