The deodorizing solution used in the present invention is not particularly limited, and conventionally known ones can be used. For example, a compound containing a complex of Mn (II) ion and an organic acid (JP-A-1-290685), a coordination compound of Fe (II) ion and an organic acid (for example, JP-A-60-66753).
No.) etc. Preferably, the deodorant solution comprises a water-soluble Mn (II) salt solution and at least one selected from ascorbic acid and citric acid in a predetermined molar ratio, for example, Mn.
The molar ratio of (II) to at least one of ascorbic acid and citric acid is in the range of 1: 0.1 to 1: 1. Further, a small amount, preferably 0.25 to 0.75 mol, of an aqueous solution of copper sulfate is added to this Mn-containing deodorant solution per 1 mol of Mn.

In the present invention, various surfactants are used as the foaming agent. Specific examples are as follows. Examples of the nonionic surfactant include ether type polyoxyethylene alkyl ethers such as polyoxyethylene nonylphenyl ether and dodecyl polyoxyethylene ether. Further, ester / ether type polyethylene glycol fatty acid ester, for example, polyethylene glycol oleic acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene sorbitan monopalmitic acid ester and the like can be mentioned.
As the anionic surfactant, a fatty acid monocarboxylic acid salt, for example, sodium laurate, N-acyloylglutamate, for example, sodium nauroylglutamate,
And so on. Examples of cationic surfactants include amine bases, alkylamine salts (stearylamine hydrochloride, etc.), quaternary ammonium salts (alkyltrimethylammonium salt-stearyltrimethylammonium chloride, dialkyldimethylammonium salt-distearyldimethylammonium chloride, alkyldimethyl). Benzyl ammonium salt-lauryl dimethyl benzyl ammonium chloride, etc.). An amphoteric surfactant can also be used. In the present invention, as the foaming stabilizer, a surfactant is appropriately selected and used. For example, a nonionic surfactant is preferable, and when it is acidic, an ether type is preferably used. Further, a polymer compound is used, and sodium salt of carboxymethyl cellulose (SCMC),
A complex salt of guar gum or an ionic polymer (such as cationized cellulose) and a fatty acid salt (such as N-coconut oil fatty acid acyl-L-glutamic acid triethanolamine) can also be used. Further, addition of higher alcohols can further improve the emulsion stability.

In a preferred embodiment of the deodorant mousse of the present invention, the deodorant solution is mixed with a thickener, an emulsifier (foaming agent) and an emulsion stabilizer to prepare a foaming stock solution. Examples of the thickener include polyvinylpyrrolidone (PVP), vinylpyrrolidone diethylsulfate-N, N-dimethylaminoethylmethacrylic acid copolymer (trade name Gaffcut 734), chitin, hydrolyzed collagen, and peptide salt.
This thickener thickens the liquid and fixes the foam, so
The% drainage time (the time when the aqueous solution contained in the bubbles drains due to gravity and is excluded from the bubbles) is delayed by the addition of these thickeners. The above-mentioned various surfactants can be used as emulsifiers of polyoxyethylene sorbitan monolaurate, polyoxyethylene sorbitan monooleate,
A nonionic activator such as polyoxyethylene cetyl ether or polyoxyethylene lauryl ether is used,
As the nonionic surfactant, the ether type is suitable for the acidic liquid.
As an emulsification stabilizing aid for, settosterial alcohol,
Examples include palmityl alcohol and propylene alcohol.

This foaming stock solution is filled in a container. At this time, as the propellant, DMS (dimethyl ether) and L
A mixture of PG (liquefied propane gas) is used, or an optimum one such as N ₂ gas liquid, or pressurized air, carbon dioxide gas is selected, and usually 0.2 to 4 kg / c depending on the shape of the container.
The pressure is set to about m ^2, and the foaming agent is jetted in a gaseous state when used. Deodorant mousse agent is ejected to the surface layer of an aqueous solution or solid containing malodorous gas (malodorous gas such as ammonia, trimethylamine, hydrogen sulfide, methyl mercaptan, dimethyl sulfide, nitrogen-containing compounds and sulfur-containing compounds) to deodorize. The bubbles are covered with a layer to suppress the generation of odorous gas emitted to the outside and deodorize it. In another embodiment of the deodorant mousse, the above deodorant liquid is a paste or stabilizer and a surfactant (foaming, foaming stability).
Mix with an emulsifier to form a foaming stock solution. As the sizing agent or stabilizer, there are used chitin or chitosan, acrylate, vinyl acetate and polyvinyl alcohol such as diethyl vinylpyrrolidone sulfate, N, N-dimethylaminoethyl methacrylic acid copolymer, and diethylene glycol. As the foaming emulsifier, anionic, cationic, or nonionic ones can be used, and preferably nonionic polyoxyethylene nonylphenyl ether (polyoxyethylene alkyl ether sucrose fatty acid ester) is used. As the foaming stock solution, it is most preferable to add a sizing agent or a stabilizer and a surfactant (foaming, foaming stable) emulsifier to the deodorant solution, but a composition without the sizing agent or the stabilizer may be used.

[0008] mixture The composition of propellant and DME (dimethyl ether) liquefied propane gas, DME and N ₂ Gasuka N ₂ gas alone, "carbon dioxide gas", DME and the compressed air or compressed air alone is used. The foaming stock solution is filled into a container under a pressure of about 4 kg / cm ² . The can material used in the present invention is not particularly limited, but an inner surface epoxy phenolic coated aluminum can is preferably used. In the present invention, the concentration of the deodorant solution in the foaming stock solution is not particularly limited and varies depending on the concentration of the malodorous component of the malodorous source, but in the case of the Mn-organic acid complex, the Mn concentration is 1.
It is set to 3 to 5.5%, preferably 2.0 to 4.0%. The concentration of the thickening and fixing agent is 0.25 to 3%, preferably 0.5 to 2.5%, more preferably 1.0 to 2.0%. The concentration of the paste or stabilizer is 10 to 0.18%,
It is preferably 8 to 2%, more preferably 5 to 2%.
The emulsifying / dispersing agent is 9 to 1%, preferably 7 to 2%, and more preferably 5 to 2%. Emulsion stabilizing aid is 8 to 0.2
%, Preferably 7-0.2%, more preferably 5-0.
2% Further, in a spray can using the foamable deodorant stock solution of the above composition, the case material used as the mousse generation container is preferably an internal epoxy phenolic coated aluminum can, but in a normal can material, the foam stock solution is corrosive. Therefore, if the foaming stock solution is stored in an aluminum can for a long period of time, pitting corrosion may occur at the nozzle connecting portion of the aluminum can, which may cause a problem in maintaining pressure. The cause of pitting corrosion is considered to be hydrogen ions generated by dissociation of organic acids coexisting in the foaming stock solution. Since the degree of pitting corrosion depends on the hydrogen ion concentration, NaOH, Na ₂ CO ₃ , NaHC should be added to the foaming stock solution beforehand.
If you add an alkali such as O ₃ to raise the pH,
Corrosion can be suppressed. Such addition of alkali is carried out, for example, by adding a weak alkaline aqueous solution containing the above-mentioned alkaline salt to the foaming stock solution, or by changing citric acid contained in the Mn-organic acid complex into a citric acid Na salt. However, if the alkalinity is strong, precipitates such as hydroxides will be generated from the foaming stock solution, so the pH will be about 0.5-.
The optimum pH can be obtained by increasing the pH by about 1.0. The inclusion of EDTA can prevent the formation of precipitates such as hydroxide. The deodorant mousse of the present invention is the one in which the propellant is filled inside in the case of the above spray can, but the propellant is placed outside and the propellant is appropriately blown into the foamable deodorant stock solution in a necessary amount. Alternatively, a certain amount of mousse may be taken out. Such a method and apparatus will be described below.

An embodiment of this deodorizing method will be described with reference to FIG. FIG. 1 shows a deodorizing device. In the figure, 1 is a mousse generating container in which the foaming deodorant stock solution 2 is charged, 3 is an air compressor, 4 is an air vent pipe, 5 is an air blowing pipe with many holes, 6 is a generated mousse, and 7 is The mousse take-out pipe, 8 is a mousse injection nozzle. Reference numeral 9 is an inlet for the foaming stock solution. Reference numeral 10 is an air pipe bypass pipe, 11 is a solenoid valve (timer), 12 is a solenoid valve (timer), and 13 is a check valve. In the above-mentioned device, the air compressor 3 is operated to set the air vent pipe 4 in the mousse generation container 6.
A fixed amount of pressurized air (or pressurized nitrogen gas) is blown from the air blowing pipe 5 into the foamable deodorant stock solution to generate a large number of mousses 6, which are then passed through the mousse feeding pipe 7 and the mousse injection nozzle 8 To spray the object to be processed (for example, inside the toilet bowl). Although not shown, an operation switch of the air compressor 3 is provided near the mousse injection nozzle 8. Pressurized air has a pressure of about 3 to 5 kg / cm ² . Therefore, the spray nozzle 8 is appropriately installed according to the object to be treated, but in the case of a toilet, the mousse is sprayed from the spray nozzle 8 into the toilet bowl, and then the toilet is used and the excrement after use is washed away. In the case of the above-mentioned apparatus, the foaming undiluted solution itself is the same as that of the above-mentioned spray can, but it does not use a propellant gas but blows air or the like from the outside to generate bubbles. An example of the operation of the apparatus of FIG. 1 of the present invention will be described. Inject into the mousse generation container 1 from the 2000 cc foaming deodorant injection port 9 and use the air compressor 3
Air vent pipe 4 (caliber 5m by pressure of 3-4kg / cm ²
m. Teflon tape), and through the air blowing pipe 5 and porous foaming equipment, foaming deodorant stock solution 2
Is a device that foams mousse 6 into a mousse shape 6 and passes through a mousse take-out pipe 7 (5 mm Teflon tape) to inject about 6 cc of mousse 6 from a mousse injection nozzle 8 to remove odor (333 times, 6 times a day, 55 days). When the mousse remains in the pipe, the pipe is clogged. Therefore, the bypass pipe 10 for the air pipe (5 mm diameter Teflon tape) is provided, and the solenoid valve 12 is opened and the solenoid valve 11 is closed by turning on the switch. Injection operation, the injection is completed in about 3 seconds, and after about 3 seconds, the solenoid valve 12 is closed, the solenoid valve 11 is opened, and the remaining mousse is injected, and the check valve 13 operates to generate air in the generation container 1. Stop the back flow and dry the mousse in the container to control solidification. In all cases, each control is electrically controlled and is controlled by a built-in timer. In the above example, a gas was introduced into the foamable deodorant stock solution to form a mousse (by the aeration method), but a stirring method (shaking method) for generating foam by stirring or shaking, a container, A heating method of heating and boiling (incorporating an electric heat source) or the like may be appropriately adopted, or these may be combined.

EXAMPLES Next, the present invention will be described in more detail based on examples. Example 1 A foaming stock solution was prepared with the following formulation.

[0011]

[Table 1]

Next, the above foaming undiluted samples Nos. 1 to 3 were filled in a 100 ml can container together with a propellant as described below. The internal pressure was about 4 kg / cm ² . Stock solution / propellant ratio: 93/7% Propellant composition: DME / LPG 4.0 = 30/7
0% stock solution / propellant filling amount: 83.7 / 6.3 g = 90 g (about 93 ml) In this way, canned deodorant mousse samples 1 to 3 were prepared.

Deodorant test Ammonia water (150ppm) in a 300ml beaker
150 cc was put in, about 2 g of the deodorizing mousse agent sample 2 was sprayed on the top, and the foam was covered with a thickness of 10 mm, and the ammonia concentration above the film of the foam was measured with a detector tube. The results are shown in Table 2.

[0014]

[Table 2]

From the above results, it was found that the foam film was destroyed in 30 minutes and the deodorizing effect was lost, and the deodorizing effect was 0 when dissolved in water. In reality, assuming that the NH ₃ concentration of human urine is 15 ppm, the following table is inferred from the results of the above table, and since the malodor source is washed off with water, no odor is present.

[0016]

[Table 3]

Example 2 Foaming stock solution sample No. 1 of Example 1 3 was prepared according to the composition shown in Table 1 (Mn (II): citric acid: ascorbic acid molar ratio 1: 0.8: 0.2, and Mn complex concentration 20).
% Solution (solution U) was added at 20%. ). PH of this solution
Was about 1.90. Next, except for adding a small amount of sodium hydroxide aqueous solution as the weak alkaline aqueous solution, the sample No. Prepare a foaming stock solution in the same manner as in 3, and adjust the pH of the solution to 2.
5 were prepared. Using this liquid (Sample No. 4, use of sodium citrate and addition of weak alkaline aqueous solution), a can abuse test was conducted (40 ° C., 2 months). As a result, almost no corrosion of the can was observed, and it was found that upright and upside down can be used (microscopic test results). In addition, the sample No. When the odor removing ability test with ammonia (deodorant test) was conducted using the liquid of Example 4 in the same manner as in Example 1, almost the same results as in Example 1 (Tables 2 and 3) were obtained.

EFFECTS OF THE INVENTION In the present invention, a foamed aerosol foam enables a relatively small amount of deodorant liquid to be applied effectively and uniformly over a wide range, and is excellent as a gas-liquid contact type deodorant. According to the present invention, since the malodor source is covered with a relatively thick layer of deodorant foam, the malodor does not diffuse into the external atmosphere. Also, when used in a flush toilet, etc., the excrement is washed off in a state of being covered with a foam layer, so that no odor remains. Further, even if the bubbles of bubbles are broken and liquefied, the deodorant liquid acts on the source of the bad odor to exert the deodorizing effect. Further, by raising the pH of the foam deodorant stock solution, corrosion of the aluminum can can be prevented for a long period of time.
