Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a deodorant that eliminates bad odors and strange odors. [Background Art] Generally, bad odors and strange odors are caused by exhaust smoke and liquid from factories, cigarettes, deep floors, In addition, kitchen waste is the source, and there are a wide variety of types of foul odors and strange odors. especially,
In homes, rooms are often kept closed when heating and cooling equipment is in operation, so countermeasures against these foul odors have become a major problem.

There are four ways to eliminate these bad odors and strange odors:
There are two ways.

■ Sensory deodorization method: A method of masking bad odors and foreign odors using aromatic substances (fragrances).

■Physical deodorization method: A method that removes foreign odors through ventilation and diffusion, or uses activated carbon to absorb odors.

■ Chemical deodorization method: A method of chemically reacting (neutralization, addition, condensation, oxidation, etc.) with malodor and off-flavor components to make them odorless.

■ Biological deodorization method: A method that reduces and kills bacteria that cause spoilage, prevents spoilage, and prevents the occurrence of bad odors.

The sensory deodorizing method (2) is a method that is mainly practiced in ordinary households, and is a method that uses the scent of the deodorant itself to deodorize bad odors and foreign odors. However, with this method, it is difficult to balance the fragrance and odor, and people have different tastes in the scent of deodorants, which can sometimes make them feel disgusted. It's hard to say. Although the physical method (2) is widely used, there are problems in that it requires equipment, that the room temperature fluctuates, and that activated carbon does not have a long-lasting adsorption effect on bad odors and off-flavor components. In addition, chemical deodorization method (2) is not common because it is extremely difficult to select a substance that effectively reacts with a wide variety of malodorous components, and care must be taken in handling the chemicals used. Furthermore, the biological deodorizing method described in (2) also requires equipment, and has the disadvantage of slow onset of effects. At present, each deodorizing method has its own advantages and disadvantages.

[Purpose of the invention]

This invention was made in view of the above circumstances, and an object of the present invention is to provide a deodorizing agent which is itself odorless and has a high deodorizing effect on various malodorous components.

[Disclosure of the invention]

In order to achieve the above object, the gist of the present invention is to provide a deodorant containing colchicine, an alkaloid that is a secondary metabolite of plants, as an active ingredient extracted and purified from plants.

Colchicine has the structure shown below.

This colchicine is produced in saffron and related plants of the Liliaceae family, and inhibits the function of the spindle system during cell division.
It is known to have a unique physiological effect of generating polyploid chromosomes, and is used as a pesticide for the purpose of producing polyploid plants.

The inventors have been investigating the deodorizing effect of plant metabolites for the purpose of removing bad odors from the living environment, and found that colchicine, one of the alkaloids mentioned above, exhibits a great deodorizing effect. , this invention has been completed.

Regarding the usage of the deodorant obtained in this way,
It is not particularly limited. When used as a liquid deodorant, polyhydric alcohols such as glycerin and propylene glycol are usually used as additives to prevent the deodorant from scattering and to act as a preservative.

This deodorizing component can also be used in solid form. In this case, the above deodorizing liquid may be mixed with a porous (or permeable) inorganic material such as unglazed china clay, the deodorizing component is adsorbed onto the surface of the carrier, and this is used by filling it into a container, etc. Alternatively, there are methods such as mixing it with gelatin and using it in a solid form.

The deodorant produced in this manner is itself odorless and can effectively and quickly contribute to the deodorization of a wide range of hydrogen sulfide, ammonia, amines, mercaptans, and the like.

Hereinafter, this invention will be explained based on examples.

(Example 1) 1 g of commercially available colchicine was dissolved in 100 g of a water-ethylene glycol 1:1 solvent, and 1 wt% (hereinafter referred to as "
%) solution was prepared and used as a deodorant.

In order to examine the deodorizing effect of the deodorant, the following evaluation was performed. There were 10 panelists and it was ammonia.

Target odors include ethyl mercaptan, nicotine, trimethylamine, and hydrogen sulfide. Inject 200μβ of each odor aqueous solution into a 10Qcc glass container that can be tightly closed.
A panel was asked to evaluate the odor. The concentration of the aqueous solution of each odor was io”% ammonia and 10% ethyl mercaptan.
%, nicotine 10-1%, trimethylamine 10
%, hydrogen sulfide 10%. Thereafter, 100 μβ of the deodorizing solution was poured into each container, and the panelists were asked to evaluate the odor again. The odor intensity level was evaluated on a 6-level scale shown in Table 1 below. It can be said that the larger the difference in the odor level before and after adding the deodorant, the greater the deodorizing effect. The results are shown in Table 2. The numerical values in the table are the average values of 10 panelists.

(The following is a blank space) As shown in Table 1 and Table 2, the intensity level of each odor was significantly reduced by the addition of the deodorant, indicating a deodorizing effect.

(Example 2.) 100μ of the 1% solution of deodorant obtained in Example 1! 10
% ethyl mercaptan aqueous solution; 200 μl was added to a glass container with a stopper, and after shaking for 1 minute, 2 cc of gas was collected from the head space of the container with a syringe, and the concentration of ethyl mercaptan was measured by gas chromatography. . The detector used was F-PD (Flame Photometric Detector).

In order to examine the deodorizing effect, measurements were made in the same manner before the addition of the deodorant, and the odor removal rate was calculated from the concentration ratio before and after the addition of the deodorant.

As a comparative example, 100μ of water was used instead of deodorant under the same conditions.
The removal rate when 1 was added was calculated. The results are shown in Table 3.

Table 3 As shown in Table 3, the odor concentration was significantly reduced by adding the deodorant.

(Example 3) In place of ethylmercapkun in Example 2, a 10% aqueous solution of trimethylamine and a 10% acidic aqueous solution of hydrogen sulfide were prepared, the same tests were conducted, and the concentrations of each were measured by gas chromatography and removed. I met the rate. As the detectors, an FTD (alkaline thermal ionization detector) was used for trimethylamine, and an FPD was used for hydrogen sulfide. The results are shown in Table 4.

Table 4 As shown in Table 4, the deodorant according to the present invention also has a deodorizing effect on trimethylamine and hydrogen sulfide.

〔Effect of the invention〕

As seen above, in this invention, colchicine, which is an alkaloid contained in plants, is used as an active deodorizing ingredient, so the deodorant itself is odorless, poses no danger to the human body, and can be used in any form. A deodorant can be obtained. That is, since this deodorant itself is odorless, it does not cause disgust in people due to its own odor unlike conventional deodorants, and does not require large-scale equipment. Furthermore, since it can deal with a wide range of bad odors such as ammonia, amines, and ethyl mercaptan, it can effectively deal with bad odors in factories, in the home, and even in toilets.
