Description

[Detailed description of the invention]

[Technical Field] This invention relates to a deodorant that eliminates bad odors and foreign odors. [Background Art] Generally, the sources of bad odors and strange odors are factory smoke and waste liquid, cigarettes, human waste, kitchen waste, etc., and there are a wide variety of types of bad odors and strange odors. Particularly in homes, where rooms are often kept closed when air-conditioning equipment is in operation, countermeasures against these foul odors have become a major problem. There are four ways to eliminate such bad odors and strange odors: 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, condensation, oxidation, etc.) with malodor and off-flavor components to make them odorless. Biological deodorization method: A method that kills bacteria that cause spoilage, prevents spoilage, and prevents the occurrence of bad odors. The sensory deodorization method is a method that is mainly practiced in ordinary households, and it uses the scent of the deodorant itself to eliminate bad odors and foreign odors. However, with this method, it is difficult to balance the scent and odor, and the scent of deodorants has different tastes and can sometimes cause a feeling of disgust. It's hard to say. Although this physical method 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 methods are 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 in handling the chemicals used. Furthermore, the biological deodorizing method also requires equipment and has the drawback 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, users devised and proceeded with the development of the use of active ingredients found in plants as a deodorizer that itself is odorless and does not require large-scale equipment. 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 deodorizing agent that is odorless itself and does not require large-scale equipment. The purpose is to provide a deodorizing agent that exhibits a high deodorizing effect. [Disclosure of the Invention] The present invention is a deodorizing agent against hydrogen sulfide, which is extracted from at least one of the group consisting of holly oleracea, thorn, thornbush, linden, lily, butterbur, persimmon, quercus, mountain oak, fern, and ash. The gist of the present invention is a deodorant characterized by using an extracted component as an active ingredient. That is, the deodorant according to the present invention is a deodorizer that contains holly oleracea, apricot oleracea, japonica oleracea,
Extracting the bark, heartwood, leaves, stems and fruits of at least one of the group consisting of lilac, butterbur, persimmon, Quercus, mountain oak, fern and ash, for example, with water or a hydrophilic organic solvent, or a combination thereof. It has a deodorizing effect, especially against hydrogen sulfide. This invention will be explained in detail below. The raw materials for the deodorant of the present invention include holly oleracea, apricot, japonica, chinensis, lilac, butterbur, persimmon tree, quercus, mountain ash,
Bark, heartwood, leaves of ferns and ash,
Stems and fruits etc. can be used. The extraction solvent used in this invention is
Water and a hydrophilic organic solvent, such as alcohols such as methanol, ethanol, and propanol, and ketones such as acetone and methyl etketone, are used alone or in combination. An example of an extraction method is steam distillation, in which the raw material plant is passed through a steam distiller to remove components other than the active ingredients (fragrant components) from the raw material to make it odorless. Next, the raw material residue is filtered 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 used after being concentrated. However, the method for extracting the deodorizing component is not limited to the above method, and the deodorizing active component may be obtained by filtration after the hot water extraction described above. The manner of use of the deodorizer obtained in this way is not particularly limited, but liquid,
It is used in a wide variety of ways depending on the application, such as in a spray form, impregnated into a carrier, and molded into powder, tablets, and granules. 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 adsorbing on the surface of a solid carrier,
The weight ratio of deodorant and carrier is (deodorant):(carrier)=10
A ratio of ~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, apricot, Japanese oak, Chinese forage, lilac, butterbur, persimmon tree, Quercus japonica,
Deodorizing active ingredients were extracted from the leaves of Asus pericarp, fern, ash tree, and ash tree, using a mixed solvent of water and methanol. with this
A 1wt% (hereinafter abbreviated as "%") aqueous solution was made 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. that odor
It was evaluated by 10 panelists. As a comparative example, the odor was also evaluated when the same amount of water was added instead of the deodorant. The results are shown in Table 2.

[Table] As can be seen from the table, the odor level was significantly reduced by adding the deodorant. Example 2 100μ of the 1% aqueous deodorant solution obtained in Example 1
was added to a sealed glass container containing 200μ of a hydrogen sulfide aqueous solution, and after shaking for 1 minute, 2 c.c. of gas was collected from the head space of the container with a syringe.
The concentration of hydrogen sulfide was measured by gas chromatography. The detector used was FPD (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 determined from the concentration ratio before and after the addition of the deodorant. For comparison, deodorants were produced using plants other than the raw material plant groups of the present invention described above in the same manner as in the examples, and odor removal rates were determined. These results are shown in Table 3.

[Table] Example 3 Holly osmanthus, thorn,
A liquid mixed with equal amounts of 1% aqueous solution of Tsuwabuki,
As in Example 2, it was subjected to gas chromatography using FPD. The results are shown in Table 4.

〔Effect of the invention〕

As seen above, in this invention, the specific plant is used as a deodorant raw material, and the ingredients extracted from such raw material are used as active ingredients.
The deodorant itself is odorless, poses no danger to the human body, is inexpensive, can be used in any form, and has a high deodorizing effect against hydrogen sulfide.
