DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preliminarily treating places where bad odor sources are dumped or thrown in, such as water in and around a toilet bowl of a flush toilet, a simple toilet, and various storage containers for garbage and the like. And a foam deodorant.

[0002]

2. Description of the Related Art A flush toilet, a simple toilet, various storage containers for garbage and the like are typical odor sources at home. For this reason, various deodorants have conventionally been proposed to deal with these malodor sources. For example, a deodorant sprayed on a malodor source is typical. Further, for toilets, liquid drop-type deodorants and solid foam deodorants which are treated before using the toilet are also known. For example, as the former example, there is an invention disclosed in Japanese Patent Application Laid-Open No. Sho 57-164063, which discloses an aromatic deodorant composition in which a liquid comprising an oily substance containing a fragrance and a deodorant and a surfactant is placed in a flush toilet. To form an oil film and block off offensive odors. As an example of the latter, there is an invention disclosed in Japanese Patent Application Laid-Open No. 6-105893, which promotes the generation of carbonate and gas that generates carbon dioxide. A mixture of an organic acid or an inorganic acid, a surfactant, and the like is poured into a flush toilet and foamed, and the unpleasant odor of the excrement is sealed in the foam.

[0003]

The conventional deodorant is a type of deodorant which is mainly treated after the generation of offensive odor. Therefore, the odor cannot be suppressed immediately after the generation of offensive odor. The stench tends to diffuse into the space,
Also, in order to prevent this, a large amount of deodorant must be used, and there is a problem in efficiency. In addition, even if an attempt is made to use a liquid drop-type deodorant to be treated before use of a toilet as described above for an odor source targeted by the present invention, a fragrance and a deodorant composition are used as an aromatic deodorant composition. Because it is a liquid agent consisting of an oily substance containing a odorant and a surfactant, even if it was treated before putting a bad odor source into a simple toilet or trash box without any accumulated water other than a flush toilet, a sufficient effect was not obtained. . Also, as described above,
Even if an attempt is made to use a solid foaming deodorant for a malodor source targeted by the present invention, as a foaming deodorant, a carbonate generating carbon dioxide and an organic acid or inorganic acid promoting gas generation, an interface Since the mixture of the activator and the like reacts with water and foams, no effect can be expected at all in a state where there is not enough water, that is, in a simple toilet trash box without accumulated water.

[0004] The present invention is intended to solve the above-mentioned problems. Basically, the present invention eliminates the bad odor that occurs every time a bad odor source is dumped or thrown into various containers such as toilets and garbage.
After the foam is formed by pre-treating the foam at the position where the malodor source is discarded or thrown in, after the malodor source has passed through the foam, the foam is re-coated on the passageway to effectively remove the malodor. It is intended to provide a deodorant that can be blocked. The present invention also provides a foam deodorant which can impart the following effects to the malodor sources in the above-mentioned situations, or which actively exerts this effect. It is assumed that.・ Effects such as being effective against various malodorous components and maintaining deodorization for a long time; ・ Effects such as comfort by imparting a fragrance; ・ Effects such as generation of mold and suppression of bacterial growth or elimination of bacteria; Action effects such as preventing the invasion of pests or killing the introduced pests;-Preventive action effects such as making it difficult for dirt to adhere or to be easily removed.

Usually, the total amount of the surfactant is 0.5 to 5.0% by weight, preferably 1.0 to 3.0% by weight based on the stock solution. % By weight is desirable. If the amount of the surfactant is small, the stability of the stock solution may be poor or foaming may not be performed. If the amount is too large, the viscosity of the stock solution may be changed, and foaming property may be changed because the stability at low temperature is deteriorated. .

Film-forming agent The film-forming agent has a function of stabilizing and maintaining air bubbles and a function of forming a thin film on the surface of a malodor source, thereby eliminating odor during foam formation for a long time. In addition, even after deodorization, it is possible to suppress the emission of malodorous components and to increase the duration of efficacy. The film-forming agent used in the present invention is a water-soluble resin such as polyvinyl alcohol, polyethylene glycol, polypropylene glycol, sodium polyacrylate, methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, carboxymethyl cellulose, hydroxypropyl cellulose, methyl hydroxypropyl cellulose, viscose, etc. Cellulosics, starches such as carboxymethyl starch, dialdehyde starch, and soluble starch; plant mucilages such as trolloay, tragacanth gum, and gum arabic; mucous substances such as dextran and lepan; microorganisms such as agar; , Glue, gelatin, casein, collagen and other proteins, as well as polyvinylpyrrolidone, higher fatty acids, carbohydrates Shi vinyl polymers, and the like.

Spraying Method The spraying method of the foam deodorant of the present invention is not particularly limited. For example, an aerosol container using a propellant such as LPG, DME, carbon dioxide, nitrogen gas, etc.
A foam discharge container that mixes and foams with pressurized air, or a container equipped with tools for compressing and high-pressure gas inside the container, and a device that introduces compressed air to the outside of the container to increase the pressure inside the container As a method and others, a trigger method and the like can be mentioned. As the spray container, a container made of various synthetic resins can be used in addition to a metal container. As the foam discharge container, any one may be used as long as the undiluted solution is mixed with air and discharged in a foam state, for example, a squeeze former used by pressing the body of a soft container, a cap provided with a pump mechanism And a pump former that is used by pressing. When a propellant is used, generally known propellants can be used. For example, propane, normal butane, isobutane,
Examples thereof include isobutylene, dimethyl ether, carbon dioxide, nitrogen gas, and chlorofluorocarbon gas which has no practical problem. Further, the gas pressure at 20 ° C. is desirably 1.5 to 5.0 kg / cm ² · G, preferably 2.0 to 4.0 kg / cm ² · G. That is, when the gas pressure is low, the amount of foam cannot be obtained because the ejection force is weak, and when the gas pressure is high, the bubbles are scattered because the ejection force is too strong, and the rebound is large and wasteful.

In the deodorant aerosol of the present invention, the mixing ratio of the stock solution and the propellant is such that the stock solution: propellant = 6 by volume ratio.
0:40 to 80:20, preferably 65:35 to
A range of 75:25 is shown. It is desirable to increase the proportion of propellant to increase the expansion rate. However, if the ratio of the propellant is too high, the standard of the High Pressure Gas Safety Law (35 ° C 8kg)
/ Cm ² · G or less), which is not preferable for safety. The features of the present invention are as follows:
An object is to form an enormous and sufficient amount of foam in a malodor source with a processing amount and a processing time as small as possible, and to maintain the foam in a stable state for a predetermined time. The injection amount per unit time is preferably 0.5 to 10 ml / sec. The injection amount may be used according to the usage scene.
Injecting for up to 3 seconds is sufficient, and a time during which processing can be performed instantaneously is preferable. In this way, when the water temperature in winter is low or when the number of times of use is repeated and the internal capacity decreases, the performance of foam due to the decrease in the internal pressure of the can does not decrease, and the number of uses per bottle is large and economical It is.

When an aerosol container is used in the present invention, the button has an injection hole diameter of 1.0 to 2.0 mm,
A valve having a stem hole diameter of 0.3 to 0.6 mm and a lower hole diameter of the housing larger than the stem hole diameter is preferable.

Foam Foam is an important factor in the present invention in terms of expansion rate and hardness. Foam Expansion Rate The foam expansion rate is more than 10 times the spray volume. The measurement of the expansion rate of the foam is a numerical value obtained by injecting a predetermined amount into a 500 ml measuring cylinder at 25 ° C., measuring the volume of the foam when the expansion of the foam is completed, and dividing the volume of the foam by the injection capacity. When the malodor source is discarded or charged, the foaming amount sufficient to cover the malodor source is 10 times or more, preferably 20 times or more, and more preferably 50 times or more. When the hardness of the foam is indicated as a weight of 30 g or less so that the measuring body is buried in the foam by 1 cm, the foam has a flexible and elastic foam and becomes a stable foam for a long time. The odor source that has entered above sinks into the foam and disappears, blocking the emission of odor. In this case, if the re-covering time of the approach path of the offensive odor source is within 1 minute, the effect becomes higher. if,
If a moderate foam is not obtained, the malodor source will ride on the foam or penetrate the hole and cannot naturally block the approach path, so that the malodor component leaks and diffuses into the outside air. The appropriate value of the foam hardness is different depending on whether the applied surface of the foam is a water surface or a non-water surface, but these are related to the expansion rate of the foam, and if the foam property is to be re-coated after dumping or putting in a foul odor source. There is no particular limitation.

EXAMPLES The present invention will be specifically described below with reference to Examples, Comparative Examples and Test Examples, but it goes without saying that the present invention is not limited to these Examples. Examples 1 to 18, Comparative Examples 1 to 5 and Examples of Commercial Products The following tests were performed with each formulation shown in the upper part of Table 1. Deodorant effect A predetermined amount of foam is sprayed into a 1-liter beaker, and about 100 g of stool is dropped from above. Immediately after that, the stool odor was investigated sensoryly. Expansion rate of foam Measure the weight of the can. A 500 ml graduated cylinder was sprayed for about 2 seconds, and the volume of the foam when the expansion of the foam stopped was measured. The weight of the can after injection was measured, the injection amount was determined by the weight loss before and after injection, and the injection capacity was calculated from the specific gravity. The volume at the time of complete expansion was divided by the injection capacity to obtain a foam expansion rate. 100ml beaker (50m inner diameter)
m) was filled with foam, and the weight of a circular measuring object (diameter: 34 mm) embedded in 1 cm was investigated. As a physical property measuring device, a rheometer NRM-2002J type (manufactured by Fudo Kogyo) was used. Spraying a predetermined amount of foam into a 1-liter beaker, and dropping about 100 g of stool from above. Immediately thereafter, the state of the foam 24 hours later was visually inspected. Stock solution viscosity The viscosity was measured using a B-type viscometer under the following conditions. BL
It carried out at 20 degreeC and 60 rpm using an adapter. The repetition was performed three times, and the average value is shown in Table 3. <Sample Conditions of Examples and Comparative Examples> Valve: stem φ = 0.41 mm Open housing (for inversion) Button: φ = 1.4 mm straight (spout type) Contents: 220 ml Gas: LPG 2.0 kg / cm ² · G Competitors A and B are deodorant foam type

[0026]

[Table 1] <Evaluation criteria> Deodorant effect Immediately after the stool was dropped on the foam, it was investigated whether or not the stool had an odor.な い No odor at all Slightly odor × Obvious odor Expansion rate of expansion The expansion rate of expansion was represented by the ratio of the amount of expansion to the internal solution. ◎ Exceeding 50 times 0 to 50 times × less than 10 times Hardness of foam The weight when the adapter was buried 1 cm in the foam was investigated by a physical property measuring instrument. ◎ Less than 15 g More than 5 to 30 g × more than 30 g Formation of a film Immediately after dropping stool on the foam, 24 hours later, it was visually inspected whether or not the foam formed a film.明 ら か に Clearly formed Slightly formed × Not formed at all Stock solution viscosity Measured using a B-type viscometer. ◎ Less than 500 cps 00 to 5000 cps x 500
Analysis and Evaluation of Each Data Exceeding 0 cps • From the results in Table 1, it can be seen that film formation is greatly involved in the deodorizing effect. Therefore, the formation of a film can maintain effects such as deodorization, other fragrances, sterilization, insecticide, etc. over a long period of time. -Regarding the hardness of the foam, if it is within 30 g, the foam can re-form the film even after dropping the stool. In particular,
If it is 15 g or less, the film is not broken even when the stool falls because the foam is soft. On the other hand, if it exceeds 30 g, the foam becomes hard and the film cannot be formed again. The film can be reformed with an expansion rate of 10 times or more, especially 50
The film does not break at more than twice. -As described above, the bubbles are not so hard, and the larger the expansion rate, the more advantageous the film formation. -The formation of a film is related to the deodorizing effect, expansion rate, foam hardness, and stock solution viscosity. -Regarding the viscosity of the stock solution, if the viscosity is 5000 cps or less, the foam becomes soft and a film is easily formed. In particular, 5
If it is not more than 00 cps, the foam becomes softer, and the film forming agent shows a more effective effect. When the viscosity is 5000 cps or more, the viscosity increases, the foam becomes hard, the fluidity is lost, and the film cannot be reformed even when the stool falls.

Test Example 2 The following tests were conducted for Example 6, Comparative Example 2, Competitor A and Competitor B of the formulation shown in the upper part of Table 1. 2-1 Test method A deodorant basic test was performed by the detector tube method. This is the test as follows. Into a 2-liter Erlenmeyer flask, specified amounts of various odor sources were dropped, and a predetermined amount was sprayed from above. The odor concentration was measured over time using a gas detector tube. A case where no foam was sprayed was regarded as a non-treatment section. The measurement was performed 5, 30, 60, 90, and 120 minutes after the addition of the offensive odor source. Removal rate (%) = (untreated section concentration (ppm)-sample concentration (ppm)) / untreated section concentration (ppm) <Sample condition> Valve: stem φ = 0.41 mm Housing open (inverted) Button: φ = 1.4mm straight (spout type) Contents: 220ml Gas: LPG 2.0kg / cm ²・

Discussion According to the test results of Tables 2 to 5, the following points are considered. Example 6 in which the foam was good was compared with Comparative Example 2, in which the foam was bad, Example A of another company, and Product B of another company. (Example 6, Comparative Example 2, Competitor A, Competitor B)-The better the foam, the better the odor removal rate (around 80%). This is because the odor source is trapped in the film and the odor is physically reduced. I think it is suppressed. Example 6 shows a high deodorizing effect immediately after the treatment, and this effect lasts for a long time.

Test Example 3 The following stock solution was filled in a foam discharge container to obtain a foam deodorant. When the foam-like deodorant is discharged from the container, elastic foam foams with a high expansion rate, maintains a stable state for a long time, and can be used even in a method without using a propellant. (Component)% Sodium alkyl sulfate 2.6 Sodium polyoxyethylene alkyl sulfate 0.6 Polyoxyethylene glycol 5.0 Abietic acid 1.0 Purified water (Remaining amount)

Various usage situations and working states of the foam deodorant according to the present invention and the prior art are described below. 1. When the defecation is performed after the foam related to the present invention is treated on the surface of the flush toilet (see FIGS. 1 (a) to (e)). The foam of the present invention is treated on the surface of the flush toilet (a). Some of the foam is temporarily broken by dropping stool or the like, but the foam coating on the entire water surface is instantaneously regenerated by moving and covering the foam (b) to (d). As a result, the stool is discharged to the sewage together with the foam, and the odor of concern does not diffuse into the air immediately after the stool is discharged until the rinsing is performed (e). When the waste related to the present invention is treated in a simple toilet or a garbage container, and then the waste is thrown into the container (FIG. 2A)
(Refer to (e).)-Treat the foam of the present invention in a simple toilet or a garbage container (a)-Put waste into the treated foam all over the bottom of the container (b)-Part of the foam is made of waste Although it is temporarily broken by input,
(C)-(d) Wrap the entire waste with foam by instantaneous moving coating of the foam. (C)-The foam gradually disappears and liquefies as it is left to stand, but the surface of the waste is coated (coated) with the undiluted treatment solution. Also prevents the spread of odors. In particular, those in which a deodorant or a disinfectant is blended in the stock solution have a more continuous deodorant effect (e). When the waste is thrown in after treatment of the foam related to the conventional example in a simple toilet or a garbage container (FIG. 3A)
(Refer to (e).)-In the state diagram, filth is charged in the same manner as in Fig. 2 (a) to (c)-However, the hardness of the foam does not satisfy the conditions of the present invention, and the filth is broken by the filth Foam loses fluidity and does not move,
The surface of the filth cannot be covered with foam (d)-The foam gradually disappears and liquefies when left untreated, but the filth surface is not coated with the undiluted solution and the odor continues to diffuse thereafter ( e)
