Abstract

PROBLEM TO BE SOLVED: To provide a garbage deodorizing method and deodorant, for deodorizing even an order not capable of being deodorized by a conventional deodorant such as the putrid order of an egg, the putrid order of onion, or the putrid order of cabbage among the orders of garbage.SOLUTION: Spray water drops of a first liquid comprising an ethanol-containing aqueous solution or alkaline electrolytic water, and spray water drops of a second liquid which comprises an aqueous solution having pH in a range of 5-10, not containing alcohol, and containing copper ions or zinc ions are simultaneously made to exist in an atmosphere wherein an order component exists.

Description

The present invention relates to a deodorization method and a deodorization method of a new mechanism that eliminates odors that could only be removed by masking of fragrances and the like, and reduces the generation of new odorous substances.

In general, unpleasant odors in the home include a variety of odors such as toilet stool-derived urine odor, kitchen garbage odor, living room tobacco odor, door shoe odor, cloth products such as bedding, consumer sweat and body odor, etc. These are all life odors that occur in normal life.
Many of these living odors involve microorganisms. For example, kitchen garbage odor is a decaying odor that causes microorganisms to grow using food as a nutrient source and rot the food, and the cause of the odor is wide-ranging. Was difficult. For odors that cannot be deodorized by any means, a method has been adopted in which the odor is not felt by masking with a fragrance.

Conventionally, various deodorants and residential detergents have been proposed in order to eliminate odor components. Among them, physical methods and chemical methods have been proposed for odors that have already occurred.
As a chemical method, for example, a deodorant mainly composed of a salt of copper (II) ion and / or zinc ion has been proposed (for example, Patent Document 1).

  In Patent Document 1, copper (II) ions and / or zinc ion salts suppress the generation of odors, particularly the generation of nitrogen-based odors (for example, trimethylamine and ammonia). Moreover, the hearing information that copper (II) ion and / or zinc ion erase | eliminate sulfur type odor (for example, methyl mercaptan) is described.

JP2008-36386

However, copper (II) ions and / or zinc ions are hardly effective in the rotting odor of eggs, the rotting odor of onions, the rotting odor of cabbage and the like.
The object of the present invention is to provide a deodorizing method that eliminates the odor that cannot be removed by conventional methods in household garbage and does not require the use of a masking agent such as a fragrance.

The above-mentioned object is to spray a first liquid sprayed water droplet made of an ethanol-containing aqueous solution or alkaline electrolyzed water and a second liquid sprayed from an aqueous solution that has a pH of 5 to 10 and does not contain alcohols and contains copper ions or zinc ions. This is achieved by a deodorizing method characterized in that water droplets are simultaneously present in an atmosphere containing odorous components.
In order to create a situation in which the two liquids exist at the same time, it is possible to spray the first liquid composed of an aqueous ethanol solution or alkaline electrolyzed water before or simultaneously with the spraying of the second liquid.

A feature of the present invention is that the second liquid has a pH in the range of 5 to 10 and contains no alcohols, and the liquid containing copper ions and zinc ions is sprayed into an atmosphere having an odor component around the fine water droplets. This is the presence of one water-containing minute water droplet or alkaline electrolyzed water droplet, and when the first and second liquid droplets coexist, Effectively deodorizes rotten odor of eggs, rotten odor of onion, rotten odor of cabbage and garlic odor.
The coexistence state of the first and second liquid micro-droplets is best sprayed at the same time, but after spraying the first liquid, even if the second liquid is sprayed while the micro-water droplets remain Good.
In the present invention, there is a case where an alcohol odor or a new odorous substance such as an ammonia odor may be generated by spraying the first liquid, but these are in the range of pH 5 to 10 and do not contain alcohols and copper ions or Deodorized by the second liquid containing zinc ions.
The present invention requires that the fine water droplets generated by spraying the first liquid exist separately from the sprayed fine water droplets of the second liquid.
The second liquid of the present invention needs to contain no alcohols such as ethanol, and must have a pH of 10 or less and a pH of 3 or more.
That is, the second liquid may be composed of water (tap water or purified water) and deodorant metal ions, and may be a citric acid solution or acid electrolyzed water containing the deodorant metal ions. Including alcohol does not work and the pH should not be above 10.

Preferred embodiment of the invention The concentration of copper ions and zinc ions in the second liquid is suitably 0.1 ppm to 20 ppm.
This density | concentration can obtain the density | concentration which exhibits the effect of this invention by immersing copper wool or brass wool in water.
It can also be obtained by dissolving a copper salt or zinc salt in water. However, a counter anion is contained in the second liquid, and this counter anion may react with a substance in the atmosphere to cause a side effect, and a method of immersing copper wool or brass wool in water is most preferable. However, only copper ions are dissolved in water from copper wool.
The alcohol concentration of the first liquid is appropriately about 1 to 20%.
The pH of the alkaline electrolyzed water of the first liquid is 12.0 or higher, preferably 13.0 or higher.
In the present invention, since most of the smell of household garbage is deodorized, it is not necessary to use a fragrance as a masking. However, a fragrance is used as a mask for odors originating from special components or as a fragrance. It can be added to the liquid.

Example 1
As the first liquid, an ethanol 5% aqueous solution and an ethanol 15% aqueous solution were prepared. Moreover, the liquid which immersed brass metal wool in aqueous solution as a 2nd liquid was produced. The metal ion concentration was copper ion: 0.42 mg / L, zinc ion: 0.9 mg / L. The concentration was measured by ICP emission spectrometry. The first liquid and the second liquid were sprayed into a wide-mouth bottle containing a rot-smelling odor as shown in the usage form in the table below, and the deodorizing effect was measured.
The deodorizing effect is to have 10 people put their noses in the wide-mouthed bottle after spraying to determine whether or not they feel odors. If 8 or more people feel no odor, ◎, if 6-7, ○, 3 △ for 5 people, x for 2 or less.

From Table 1 below, when the first liquid is sprayed before the second liquid spraying the first liquid consisting of an aqueous ethanol solution and the second liquid consisting of an aqueous solution containing copper zinc ions, the onion, cabbage, rotten odor of eggs, Or it is clear that the action of eliminating the smell of raw grated garlic appears. Moreover, it is necessary for the first liquid to contain ethanol, and a deodorizing action appears when sprayed separately.
As described above, it can be seen that the present invention is a deodorizing method that is effective against a wider range of odors generated from household garbage than conventional deodorizing methods.
Moreover, it turns out from the comparison with Example 5 and the comparative example 5 that the 2nd liquid will not exhibit a deodorizing effect, if it is not the metal ion containing water which does not contain alcohol.

In Table 1, x1 represents that the alcohol odor remains.

Example 2
As the first solution, alkaline electrolyzed water having a pH of 13.2 was used, and a composition having the composition shown in Table 2 was further added. A large amount of metal ions is dissolved in the first liquid of Example 15, the first liquid and the second liquid of Comparative Example 11, and the first liquid of Comparative Example 12 in which brass wool is soaked in alkaline electrolyzed water. For the metal ion concentration measurement, pack test: Kyoritsu Riken Co., Ltd. was used, but it exceeded the upper limit of the measurement range, so this upper limit value was described in the examples. The metal ion concentration was measured by ICP emission analysis except for the first solution of Example 15, the first and second solutions of Comparative Example 11, and the first solution of Comparative Example 12.
Moreover, the liquid which immersed brass wool in aqueous solution as a 2nd liquid was produced. The metal ion concentration was copper ion: 0.42 mg / L, zinc ion: 0.9 mg / L. The first liquid and the second liquid were sprayed into a wide-mouth bottle containing a rot-smelling odor as shown in the usage form in the table below, and the deodorizing effect was measured.
The deodorizing effect is to have 10 people put their noses in the wide-mouthed bottle after spraying to determine whether or not they feel odors. If 8 or more people feel no odor, ◎, if 6-7, ○, 3 △ for 5 people, x for 2 or less.

From Table 2 below, onion, cabbage, rotten odors of eggs, or raw odor by spraying before or simultaneously with the second solution consisting of an aqueous solution containing copper zinc ions with alkaline electrolyzed water having a pH of 13.2 as the first solution. It can be seen that the effect of eliminating the smell of grated garlic appears. It is also clear that the deodorizing effect is not exhibited even if water is sprayed before the second liquid spray.
Moreover, from the comparison between Example 15 and Comparative Example 11, it can be seen that the effect of the present invention is not exhibited unless the second liquid has a pH close to neutral of 10 or less.

The deodorizing method of the present invention can eliminate a wider range of odors from household garbage. The deodorant of the present application is composed of a chemical substance that does not affect the human body, such as copper ions, zinc ions, ethanol, and alkaline electrolyzed water, and is a deodorant that is friendly to the human body without using a fragrance.
