Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a microbial deodorizer whose deodorizing function is stable over a long period of time.

[Prior art and problems to be solved by the invention] Conventional deodorizers include (1) those that deodorize the source of bad odors with a liquid deodorizer; Deodorizing methods (3) Combinations of the above two methods are known.However, these methods use deodorizing agents made of chemical substances.

(1) Deodorizers made from chemical substances 'c#v' are produced using a method that mainly involves chemical bonds through chemical reactions. In such cases, it is necessary to test the performance of the deodorant over time and replace it, which is a problem because it takes a lot of time and effort. It had become. In addition, when using an adsorbent substance, it is necessary to use activated zeolites or zeolites that have deodorizing functions such as adsorption to a certain extent, and their ability is limited, so the work of replacing and regenerating the adsorbent substance is time consuming. In addition, since adsorbent materials having such a deodorizing function are expensive, it takes a lot of time and effort to consider various feasibility studies for practical use.

In order to overcome the above-mentioned problems, the present invention aims to provide a deodorizing agent that can replace the microbial deodorizing agent with a long-term deodorizing effect, thereby saving labor and cost. purpose. That is, the inventors of the present invention have worked hard to develop a microbial deodorant in order to eliminate the problem of the short-lasting effects of conventional deodorants, which increases the labor and cost of replacing them. As a result of repeated research, the above-mentioned problems were solved by adding a lower alcohol, as in the microbial deodorant of the present invention.

[Means for solving the problems] The gist of the present invention is to provide microbial preparations, glucose,
A microbial deodorizer characterized by adding lower alcohol-7-al to a composition composed of ammonium chloride, a surfactant, a pigment, a fragrance, and water to maintain its performance over a long period of time. It is a drug. Preferably, the lower alkyl alcohol is methyl alcohol, ethyl alkyl alcohol, or zo[Ivinyl alcohol. In addition, the microorganism that is the raw material for the microbial preparation is Bacillus.

Parts by weight, lower alkaline: 1 - 2 - 60 parts, water 500 -
A composition of 7000 parts by weight is preferred.

Prior to the microbial deodorant of the present invention, the present inventors have invented a microbial deodorant, which is very effective in suppressing bad odors such as ammonia, but its effectiveness is After production, when the temperature ranged from 25 to 308 [], it was found that the fermentation odor was noticeable and a small amount of hydrogen sulfide was generated, so it was found that it had drawbacks as a deodorant. The purpose of this is to suppress the fermentation odor and hydrogen sulfide generation, and maintain its deodorizing properties stably over a long period of time, even though it is based on microorganisms.

To this end, we discovered a phenomenon in which the addition of a lower alcohol, particularly ethyl alcohol, to a microbial deodorant makes it possible to maintain stable deodorizing performance over a long period of time.Based on the findings of Ta.

Therefore, the structure of the deodorant of the present invention is as follows. That is, as a microbial preparation, a specific microorganism is added to an aqueous solution containing glucose, ammonium chloride, soybean meal, and bran, cultured at 20 to 35°C for 24 to 50 hours, and then dried at a low temperature to reduce moisture. ~8% by weight is used.

This is due to the two effects of active ingredients on deodorizing, such as microorganisms grown through culture, and enzymes and organic acids secreted by microorganisms during culture, and the deodorizing function is further enhanced later in an aqueous solution system to which various nutrients are added. It is a source of growth.

The microorganisms used for this purpose are appropriately selected from the following microorganisms.

That is, the deodorant of the present invention contains any of the following microorganisms, thereby improving the deodorizing effect.

That is, the microorganisms to be included in the deodorant of the present invention include (1) Bacillus genus, especially Bacillus subtilis [IAM

The above-mentioned microorganisms contained in the deodorant of the present invention produce enzymes and organic acids through their multiplication, that is, they produce organic acids that neutralize the source of malodor and enzymes that decompose the source of malodor. . This effect of producing the deodorizing active ingredient continues over a long period of time, and the amount of the source of the bad odor increases, so even if the deodorizing active ingredient is consumed, it can be replenished and regenerated for a considerable period of time.

In addition, amylase produced by the following microorganisms,
Enzymes such as ZoIJ-tease can decompose organic matter and sources of bad odors in a short time.

The deodorant of the present invention contains the above-mentioned microbial preparation io, 1000 parts by weight of glunose, and 2 to 500 parts by weight of ammonium chloride.
Preferably, the composition comprises 1 to 10 parts by weight of a surfactant, 1 to 10 parts by weight of a dye, 1 to 5 parts by weight of a fragrance, 2 to 60 parts by weight of a lower alcohol, and 500 to 7000 parts by weight of water.

The contained glucose serves as a medium and nutrient source for microorganisms, and is converted into organic acids, and if it is less than 5 parts by weight,
It does not effectively promote the growth of microorganisms, and if it exceeds 1000 parts by weight, certain microorganisms such as Aspergillus and Bacillus will increase too much, making coexistence with microorganisms of other genera impossible. .

In addition, ammonium chloride;-rum serves as a nitrogen-based nutrient source during the growth and multiplication of microorganisms; less than 2 parts by weight does not effectively promote the growth of microorganisms;
7, it becomes impossible for multiple microorganisms to coexist.

Surfactants are used to uniformly disperse components that neutralize, decompose, and dissolve malodor sources, such as microorganisms and enzymes and organic acids produced by microorganisms, and to penetrate into the surfaces and crevices of malodor sources. is necessary. Suitable surfactants include alkylaryl polyether alcohol, sodium dioctyl sultoposuccinate, and sodium oleyl taurate. If it exceeds 10 parts by weight, it is too much and increases the foaming property, lowers the commercial value, and is disadvantageous in terms of cost.

The coloring agent colors the liquid deodorant and increases its commercial value. Although any color may be used, blue is preferable because it gives a clean feeling. For this purpose, edible dyes such as Blue No. 1 and Blue No. 2 are used. is suitable. If it is less than 1 part by weight, it will not exhibit a sufficient blue color. Also, if it exceeds 10 overlapping parts, it will be too dark,
Deodorizing treatment sometimes causes stains and is also disadvantageous in terms of -1 strike.

Fragrances mask the characteristic bad odor of microorganisms themselves [
] Any substance may be used for the purpose of
If it exceeds 1 part by weight, the perfume odor will be too strong and cause discomfort, which is not suitable.

The lower alcohol contained is a core component of the present invention, and due to the presence of the lower alcohol, conventionally 25
If a certain amount is added to a microbial deodorizer that was producing a bad odor after ~20 days, it will suppress the growth of microorganisms to a certain value, even if it does not kill bacteria, and will steadily improve the deodorizing property over the long term. I was able to raise the level of miscellaneous staff to a high level. In this case, as the lower alkyl, methyl alcohol, ethyl alcohol, and norylalcohol are particularly preferred. (If C is less than 2 parts by weight, the generation of bad odor cannot be suppressed), and the deodorizing effect will be low over a long period of time.

As water, deionized water or distilled water is suitable. It serves as a medium for deodorizing ingredients. If it is less than 50 (11 ft), it has a deodorizing effect but is disadvantageous in terms of second strike.

The deodorant of the present invention can be manufactured as follows. Mix a predetermined amount of a microbial preparation obtained by mixing a predetermined microorganism, glucose, ammonium chloride, a surfactant, a pigment, a fragrance, and water, and culture with stirring at 28 to 35°C for 24 to 60 hours,
It is produced by adding and mixing lower alkyl to the obtained culture solution.

The deodorant of the present invention has a deodorizing effect by decomposing malodor-producing substances through the action of the microorganisms and enzymes contained therein.

Next, the deodorant of the present invention will be explained using specific examples, but the present invention is not limited to the following examples.

g (Cloyster Chemicals, 0625E (osmanthus aroma)), 1000 g of water was cultured with stirring at 30"C for 40 hours, and then 1.2 g of ethanol was added and mixed to create it. It was used for the following performance test. It was used for.

[Performance test of deodorizing treatment] A. B. Deodorizers with 1.2g of ethanol added to them, like the microbial deodorants in (-), B. Deodorants with 0.5g of ethanol added, C. No ethanol added (comparison) example).

The deodorant to be tested in I- below was left at 35°C, and the generation of fermentation odor was confirmed through a sensory test, and ammonia aqueous solutions with concentrations of 20 ppm and 10 ppm were prepared. , 0.1 cc of each of the above deodorants was added to 2 cc of the ammonia solution, and 30 cc of each deodorant was added in a 10 cc sealed container.
The ammonia concentration in the gas phase was measured by shaking for seconds and measuring with a soil type detector tube. For deodorants, the day immediately after manufacture is taken as day 0.
It was stored at 35°C, and the changes in ammonia concentration over time were measured and investigated every 20 times. The results are shown in Table 1.

The results shown in Table 1 show that in the comparative example in which J-tanol was not added, 40E1 had low deodorizing properties and a fermented odor was felt from the deodorant itself.

In the present invention in which -1, tanol was added, the deodorizing property did not decrease until 180 days, and no fermentation odor from the deodorant itself was detected in a sensory test.

, 2, according to the present invention, the microbial deodorizer to which ethanol has been added completely suppresses the fermentation odor that occurs when conventional microbial deodorants are stored for a long time, and also has a long-term deodorizing effect. It lasted for a long time.

[Effects of the invention] The microbial deodorant containing the lower alcohol of the present invention has the following properties:
It has the following effects.

First, the microorganisms in the microbial deodorant are activated by various nutritional sources and produce enzymes and organic acids as active ingredients that have a deodorizing effect. When lower alcohol is added when the effect reaches its maximum, the lower alcohol has a low activity of microorganisms and interrupts their growth, but does not weaken the survival of microorganisms, and after that, it suppresses microorganisms for a long period of time. Because the growth and multiplication continued extremely slowly, no fermentation odor typical of microorganisms was generated, and the deodorizing effect, which was not initially predicted, was able to be maintained almost completely over a long period of time.

Secondly, the drawbacks of the microbial deodorant of the prior application can be almost completely prevented by adding a lower alcohol, and the scope of practical application can be expanded, so it is extremely meaningful industrially.
