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 smoke and waste liquid from factories, cigarettes, frozen fields, and kitchens. The source is kitchen waste, etc., and the types of foul odors and off-odors are diverse. 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, etc.).

■ Physical deodorization method: Diluting and removing off-odors through ventilation and diffusion, adsorbing odors using silica gel or activated carbon, or enclosing odorous substances with clathrate compounds such as cyclodextrin. How to interact.

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

For example, oxidation using direct flame combustion methods or oxidizing agents such as ozone or potassium permanganate.

■ 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, it has problems such as the need for equipment, fluctuations in room temperature, and activated carbon's ability to absorb bad odors and off-flavor components is not sustainable. In addition, chemical deodorization method (■) is not common because it 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. 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. Therefore, the inventors devised the use of active ingredients found in plants as a deodorizer that is odorless and does not require large-scale equipment. The deodorizing effect varied depending on the odor.

[Purpose of the invention]

This invention was made in view of the above-mentioned circumstances, and is odorless itself, and is effective against malodorous components of acids.
The purpose is to provide a deodorizing agent with high deodorizing effect.

[Disclosure of the invention]

The present invention is a deodorizing agent for rIIi, which is a deodorizing agent for rIIi, such as Japanese butterbur, Japanese oak, Japanese oak, pomegranate, apricot, fig, mainspring, Japanese oak, Japanese persimmon, and plantain.

The active ingredient is an ingredient extracted from at least one of the group consisting of mugwort, Japanese maple, crape myrtle, white lily, Japanese aspera, fern, and Houtodyami, and the pi of a solution containing this is 8.0 to 8.5. The gist of the deodorant is: That is, the deodorizing agent according to the present invention is effective in deodorizing odors of acids such as butyric acid and acetic acid, and since the hydrogen ion concentration of the solution is set to ptts, o ~ 8.5, it has an even higher deodorizing effect. Shows odor effect.

There are no particular limitations on the method of making the solution weakly alkaline than neutral.* Na01 (, KOH, NazHPO
Examples of methods include adding an alkaline solution such as + or a buffering solution.

The higher the hydrogen ion concentration of the solution, the more effective it is at deodorizing.
The higher the height, the more careful handling it becomes, so use pi (
8.0 to 8.5.

The plant to be extracted in this invention is Tsuwabuki.

Butterbur, quercus, pomegranate, apricot, fig, mainspring, snail, persimmon, plantain, and mugwort.

The active ingredients are extracted from the leaves, fruits, stems, barks, trees, etc. of Japanese maple, crape myrtle, white maple tree, Japanese aspera, fern, and Hokutami.

The extraction solvent used in this invention includes water or a hydrophilic organic solvent, and examples of the hydrophilic organic solvent include methanol, ethanol, acetone, and the like.

The extraction method is not limited as long as it is an extraction method for removing odor components from the raw material plant.

For example, water and ethanol are added to the raw material plants mentioned above.

Adding hydrophilic organic solvents such as alcohols such as methanol and ketones such as methyl ethyl ketone and acetone,
The active ingredients are thermally extracted using a Soxhlet extractor or the like.

This extraction operation may be performed using a mixed solvent of these hydrophilic organic solvents and water. The extract obtained in this manner is subjected to a rotary evaporator or a vacuum dryer to remove water or a hydrophilic organic solvent, and the deodorizing active ingredient is obtained as a solid. The obtained deodorants may be used alone or in combination. Note that the extraction is not a single-stage extraction as described above, and if necessary, odor components of the raw material plant may be eluted and removed in advance using a hydrophobic organic solvent. Alternatively, a steam distillation method may be used.

Regarding the usage of the deodorant obtained in this way,
Although not particularly limited, liquid preparation, spray type, impregnation in a carrier, powder 1 tablet.

It is used for a wide variety of purposes, including molding into granules. When used as a liquid deodorant, the effective concentration of the deodorant solution is usually in the range of 0.05 to 5 wt%. Naturally, within this range, it can be said that the higher the concentration, the greater the effect and sustainability; however, beyond this range, the odor of the deodorant itself appears, and it tends to be unsuitable as a deodorant.

Polyhydric alcohols such as glycerin and propylene glycol are usually used as additives in deodorant liquids 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 solid form.

When used by adsorption on the surface of a solid carrier, the weight ratio of the deodorant to the carrier is (deodorant):(carrier) -10 to 0.1.
:1 is desirable.

It is sufficient if it is uniformly dispersed or dissolved depending on the use.

The deodorant produced in this manner is itself odorless and can effectively and quickly contribute to deodorizing acid odors.

Hereinafter, this invention will be explained based on its embodiments.

(Example 1) Leaves of Japanese azalea, Japanese butterbur, Quercus japonica, pomegranate, apricot, fig, mainspring, Japanese cypress, Japanese persimmon, plantain, Japanese mugwort, Japanese maple, crape myrtle, Japanese cypress, Japanese japonica, Japanese fern, and Japanese cypress were collected. 100 g of each leaf was mixed with a water-methanol mixed solvent (water; methanol = l:
l) 500mJ! At the same time, the mixture was placed in an Erlenmeyer flask, placed in a Soxhlet extractor, and refluxed at 60°C for 5 hours. The extract was passed through a colander to obtain a filtrate, which was used as a deodorant solution. Separately, a deodorizing solution of pua and o was obtained by adjusting the three extracts from each leaf with an alkaline solution. In order to examine the deodorizing effects of two deodorant solutions for each of the 17 types of plants thus obtained, the following sensory test was conducted. That is, 200 μl of a 100 pp-aqueous solution of butyric acid was placed in a glass container with a tight stopper, and the deodorizing solution made of extracts from the 17 types of plants mentioned above was mixed with an unadjusted pH and a pH of 8.
．． Add 200 μl of each sample adjusted to 0,
It was sealed tightly.

After 5 minutes, 10 people (who have a similar sense of smell) were asked to smell the odor and rate it according to the 6 grades shown in Table 1 below. As a comparative example, the odor was also evaluated when the same amount of water was added instead of the above deodorant solution.

The results are shown in Table 2.

Note that the numerical values in the table are the average values of 10 panelists.

(Margins below) As can be seen from Table 2, extracts from any plant exhibit a deodorizing effect, but the deodorizing effect was further increased by increasing the amount of extracts to pits and o.

(Example 2) The extracts of Cucumber, Butterbur and Kiri obtained in Example 1 were adjusted to a 1 wt % solution with pH 8.0.

In order to examine the deodorizing effect of the deodorant, the following test was conducted.

In a glass container with a tight stopper, add 50% of 200 ppm acetic acid aqueous solution.
After adding 1 ml of each of the above three types of solutions, sealing the container tightly and leaving it for 20 minutes at 30°C, 2+nJ of gas was collected from the head space of each container, and the concentration of acetic acid was measured by gas chromatography. The detector used was FID (Flame Ionization Detector). As a comparative example, the same amount of water was added instead of the deodorant and the concentration of acetic acid was similarly measured according to the zero-order equation to determine the odor removal rate and examine the deodorizing effect. The results are shown in Table 3.

(The following is a blank space) xo: As can be seen from the odor temperature table when the deodorant was added to the odor concentration x when water was added, an actual removal effect of 70% or more was observed for all plants.

〔Effect of the invention〕

As seen above, in this invention, the specific plant is used as a deodorant raw material, and the components extracted from such raw materials are used as the deodorizing active ingredient, so the deodorant itself is odorless. , a deodorant that poses no danger to the human body and can be used in any form is obtained; in other words, this deodorant itself is odorless, so unlike conventional deodorants, it does not contain its own odor. Patent Attorney Takeshi Matsumoto Sangetsu "SUθ" is an agent that can provide a deodorant that does not cause disgust in people, does not require large-scale equipment, and has a high deodorizing effect on acidic odors.
