Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a deodorizer that eliminates bad odors and strange odors. [Background Art] Generally, bad odors and strange odors are caused by exhaust gas and liquid waste from factories, cigarettes and floor tails, 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 in a concave state 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 bad odors through ventilation and diffusion, or using activated carbon to absorb odors.

■ Chemical deodorization method: A method of chemically reacting (neutralization, addition, 11-coupling, 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 moreover, people have different tastes in the scent of deodorants, which can cause a particular aversion window. It is difficult to say. The physical method (■) is widely used, but there are problems such as the need for equipment, fluctuations in room temperature, and the fact that activated carbon does not have a long-lasting adsorption effect on bad odors and off-flavor components. . In addition, chemical deodorization method (■) is not suitable for -C because it is extremely difficult to select substances that effectively react 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, and the current situation is that each deodorant has its own advantages and disadvantages.

In view of this current situation, the inventors devised and proceeded with the development of a deodorant that is odorless itself and does not require large-scale equipment, using active ingredients found in plants. During this period, it was found that the deodorizing effect varied depending on the target odor.

[Purpose of the invention]

This invention was made in view of the above circumstances, and is a deodorizer that is odorless itself and does not require large-scale equipment. The object is to provide a deodorant that exhibits an odor effect.

[Disclosure of the invention]

The present invention is a deodorizing agent against hydrogen sulfide, and is a deodorizing agent for hydrogen sulfide.

The gist of the present invention is a deodorant characterized in that the active ingredient is an extracted component extracted from at least one of the group consisting of aspen, fern, and ash.

That is, the deodorant according to the present invention is a deodorizer that uses holly oleracea, iris, japonica, and chinensis.

Lilac, butterbur, persimmon tree, quercus, and mountain oak.

It is obtained by extracting the bark, two heartwood leaves, stems, fruits, etc. of at least one of the group consisting of ash, ferns, and ash, for example, with water or a hydrophilic organic solvent, or a combination thereof. It has a deodorizing effect. The present invention will be explained in detail below.

Raw materials for the deodorant of this invention include Holly osmanthus,
Kiri, Tsuwabuki, Shinarengiyo, Lilac, Butterbur,
Persimmon, Quercus, and Aspen.

Bark and two leaves of heartwood of fern and ash.

Stems and fruits etc. can be used.

As the extraction solvent used in this invention, water and a hydrophilic organic solvent, such as alcohols such as methanol, ethanol, and propatool, and ketones such as acetone and methyl ethyl ketone are used alone or in combination.

Taking a steam distiller as an example, the extraction method is as follows.
The raw material residue is passed through a filter to obtain a filtrate. This filtrate contains an effective deodorizing ingredient. Therefore, it may be used as a deodorant as it is, or it may be concentrated and used. However, the method for extracting the deodorizing component is not limited to the above method, and after the above-mentioned hot water extraction, filtration. The deodorizing active ingredient may also be obtained.

The use of the thus obtained deodorant I'Li is not particularly limited, but may include liquid formulation, spray type, impregnation into a carrier, molding into powder, tablet, granule, etc. It is used for a wide variety of purposes. When used as a liquid deodorant, the effective concentration of the deodorant ranges from 0.25 to 5%. Naturally, within this range, it can be said that the higher the concentration, the greater the effect and sustainability, but if it exceeds this range, the odor of the deodorant itself will appear, making it 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 a 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.

The deodorizing agent manufactured in this way is itself odorless and can effectively and quickly contribute to the deodorization of hydrogen sulfide.

The present invention will be explained below based on examples thereof.

(Example 1) Holly osmanthus, thorn, Japanese trumpet, Chinese trumpet,
Lilac, butterbur, persimmon tree, and quercus.

Using a mixed solvent of water and methanol from aspen, fern, ash leaves, and linden berries,
The deodorizing active ingredient was extracted. This is 1wt% (hereinafter referred to as “%
(abbreviation)) was made into an aqueous solution and used as a deodorant.

In order to examine the deodorizing effect of the deodorant, the following evaluation was performed. That is, a certain amount of the above deodorizing agent was added to an aqueous solution of hydrogen sulfide corresponding to 5 of the 6 odor levels shown in Table 1 below. Ten panelists evaluated the odor. As a comparative example, the odor was also evaluated when water was added instead of the deodorant. The results are shown in Table 2.

Table 1 (blank below) As can be seen from the table, the odor level was significantly reduced by adding the deodorant.

(Example 2) 100 μl of the 1% aqueous deodorant obtained in Example 1 was added to a glass container with a tightly stopper containing 200 μl of the hydrogen sulfide aqueous solution, and after shaking for 1 minute, it was injected into the head space of the container with a syringe. Gas was sampled at 1 cc, and the concentration of hydrogen sulfide was measured by gas chromatography. The detector is F
A PD (flame photometric detector) was used.

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 determined from the concentration ratio before and after the addition of the deodorant. The results are shown in Table 3.

(Margin below) Table 3 (Example 3) Holly osmanthus and iris obtained in Example 1.

A liquid mixed with equal amounts of 1% aqueous solution of C. japonica.

As in Example 2, it was subjected to gas chromatography using FPD. The results are shown in Table 4.

As shown in Table 4, an even higher odor removal rate was obtained than when used alone.

〔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 active ingredients, so the deodorant itself is odorless.
A deodorant that is not dangerous to the human body, is inexpensive, can be used in any form, and exhibits a high deodorizing effect against hydrogen sulfide can be obtained.
