Description

[Detailed Description of the Invention] [Technical Field] This 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 waste liquid from factories, cigarettes and deep floors, and The source is kitchen waste, etc., 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: removes bad 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 households, and is a method that uses the fragrance 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 ■ is extremely difficult to select substances that effectively react with a wide variety of malodorous components, and care must be taken when handling the chemicals used. do not have.

Furthermore, the biological deodorizing method described in (2) also requires equipment and has the disadvantage of slow onset of effects, and the current situation is that 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]

The gist of the present invention is a deodorant characterized by containing a compound represented by the following general formula as an active ingredient.

Among the compounds represented by the above general formula, deodorants containing quinic acid, in which R is hydrogen, and chlorogenic acid, in which R is represented by the following general formula, as main components have particularly remarkable deodorizing effects.

H The above quinic acid and chlorogenic acid may be obtained by chemical synthesis, or they may be extracted from woody dicotyledonous plants, separated and purified. You can also use things. The extraction method and manufacturing method are not particularly limited. For example, when extracting from plants, it is preferable to perform solvent extraction from roses, oaks, sycamores, etc., and then separate by chromatography or the like.

Regarding the usage of the deodorant obtained in this way,
It is not particularly limited. When used as a liquid deodorant, a polyhydric alcohol such as glycerin or propylene glycol is usually used as an additive to prevent the deodorant from scattering or 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 wt% (hereinafter referred to as "%") of commercially available quinic acid and chlorogenic acid
Aqueous solutions were prepared and used as deodorants.

In order to examine the deodorizing effects of these deodorants, the following evaluations were conducted. That is, target odors were ammonia, ethylmercapcum, nicotine, trimethylamine, and hydrogen sulfide, and a fixed amount of each of the above deodorants was added to a solution of these odors, and 10 panelists were given the results shown in Table 1 below. The intensity of these odors was evaluated based on six levels. In addition,
The odor intensity before adding the deodorant was also evaluated. The larger the difference between the evaluation values before and after addition, the more effective the deodorizing effect is. The concentrations of each odor solution are: ammonia 0.3% aqueous solution, l-limethylamine 0.03% aqueous solution, nicodine 0.2% aqueous solution, ethyl mercaptan 2x1-ki 0% alkaline solution, hydrogen sulfide 0.05% acidic solution. It is a solution. The results are shown in Tables 2 and 3. The numerical values in the table are the average odor levels determined by 10 panelists.

(Margin below) Table 3 (In the case of chlorogenic acid) (Example 2) After drying coffee beans, they were extracted with methanol. The extract was centrifuged and concentrated to obtain crystals. This is 10
% tartaric acid solution while heating, allowed to stand, and then filtered. The filtrate was extracted several times with chloroform, the solvent was removed, and the residue was recrystallized to obtain white crystals.

When the crystals were subjected to NMR analysis and mass spectrometry, it was confirmed that chlorogenic acid was obtained.

A 1% aqueous solution of these crystals was prepared and used as a deodorant.

Add 100 μl of this deodorant to a glass container with a seal containing 200 μl of 0.2% trimethylamine aqueous solution,
After 0 minutes, add 2cc of gas from the headspace of the container using a syringe.
The concentration of trimethylamine was measured by gas chromatography.

In order to examine the deodorizing effect, measurements were made in the same manner before the addition of the deodorant, and the residual odor rate was determined from the concentration ratio before and after the addition of the deodorant. As a comparative example, water was used instead of deodorant under the same conditions.
The residual rate when μβ was added was determined. The results are shown in Table 4.

Table 4 As shown in Table 4, the odor concentration was significantly reduced by adding the deodorant.

(Example 3) The same deodorizing evaluation as in Example 2 was conducted using the 1% aqueous deodorant obtained in Example 2 and the 10% ethyl mercaptan aqueous solution. The results are shown in Table 5.

Table 5 As shown in Table 5, it also has a deodorizing effect on ethyl mercaptan.

〔Effect of the invention〕

As seen above, in this invention, the compound represented by the above general formula is used as the deodorizing active ingredient, so the deodorant itself is odorless, poses no danger to the human body, and can be used in any form. A deodorant is 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 mercapulin, it can effectively deal with everything from bad odors in factories to bad odors in the home and even bad odors in toilets.
