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, etc.).

■ Physical deodorization method: A method of diluting and removing unpleasant odors through ventilation and diffusion, or a method of adsorbing odors using activated carbon.

■ 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 has been made in view of the above circumstances, and has the object of providing 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 in that the active ingredient is an extracted component extracted from Forsythia of the family Oleaceae, genus Forsythia.

That is, the deodorizing agent according to the present invention uses, for example, the leaves, bark, and trees of Forsythia of the family Oleaceae, genus Forsythia.
It is obtained by extraction with water, an organic solvent, or a combination thereof, and exhibits a high deodorizing effect on various malodorous components. The present invention will be explained in detail below.

The extraction solvent used in this invention is water or an organic solvent. As the organic solvent, hydrophilic organic solvents such as methanol, ethanol, and acetone, and hydrophobic organic solvents such as petroleum ether, cyclohexane, and ethyl acetate are used.

The extraction method is not limited as long as it is an extraction method for removing odor components of the deodorant itself. For example, first, a hydrophobic organic solvent such as ethyl acetate or petroleum ether is used alone or in combination. , is added to the above-mentioned raw material plant, and heat extracted using a Soxhlet extractor or the like to elute and remove odor components. 1. Next, add water to the raw material residue,
A hydrophilic organic solvent such as an alcohol such as ethanol or methanol or a ketone such as methyl ethyl ketone or acetone is added, and the active ingredient is 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. Therefore, this may be used as a deodorizer as it is, or it may be used after being concentrated.

Note that the extraction may be performed by a single-stage extraction or a steam distillation method instead of the two-stage extraction as described above.

Regarding the usage of the deodorant obtained in this way,
9 tablets, including but not limited to, liquid, spray, or impregnated into a carrier; powder;

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 typically in the range of 0.25 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 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)-10-0.1
A ratio of :1 is desirable.

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.

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

(Example 1) 50 g of fresh Forsythia leaves are soaked in a methanol-water mixed solution (methanol:water - 9:1) overnight at room temperature, and refluxed using a Soxhlet extractor. The residue is passed through a sterilizer to obtain a filtrate,
Remove methanol under reduced pressure and concentrate to dryness to obtain solid 6.
2g was obtained. This was dissolved in a mixed solution of ethanol:water (1:1) to obtain a 1% 1t% deodorant aqueous solution.

In order to examine the deodorizing effect of the deodorant, the following evaluation was performed. Add 100 μl of deodorant aqueous solution to ammonia, trimethylamine, and ethyl mercaptan.

A solution of 4 types of malodorous substances (hydrogen sulfide) was added to a glass container with a tightly stopper containing 200 μl each, and after shaking for 1 minute, 2 cc of gas was collected from the head space of each container with a syringe, and each malodorous substance was analyzed by gas chromatography. The concentration of was measured. Measurements were made in the same manner before the deodorant was added, and the odor removal rate was determined from the concentration ratio before and after the deodorant was added. The results are shown in Table 1.

As shown in Table 1, the deodorant according to the present invention was found to have a high deodorizing effect on all of the above four types of bad odors.

(Example 2) The solid obtained in Example 1 was treated with propylene glycol-
In order to examine the deodorizing effect of the deodorant obtained by dissolving it in a mixed water solution (propylene glycol: water - 1:3) to obtain a 1 wt % deodorant solution, the following sensory test was conducted. That is,
A certain amount of the above deodorant solution was added to a solution of the four malodorous substances corresponding to 5 of the 6 odor levels shown in Table 2 below, and the odor was evaluated by a panel of 5 men and 5 men. . The results are shown in Table 3. Note that the numerical values in the table are the average values of 10 panelists.

As shown in Table 2, Table 3, and Table 3, it is recognized that the deodorant according to the present invention has a high deodorizing effect on all of the above four types of bad odors.

(Example 3) The deodorant solution of Example 2 was diluted four times with a propylene glycol-water mixed solution (propylene glycol: water - 1:3). When I sprayed this on shoes that had a strong odor, the odor almost disappeared.

〔Effect of the invention〕

As seen above, in this invention, the deodorant material is Forsythia genus Forsythiaceae in the family Oleaceae, and the components extracted from such raw materials are used as the active deodorizing ingredients, so the deodorant itself is odorless. This results in a deodorant that can be used in any form without any danger to the human body.In other words, this deodorant itself is odorless, so it does not have its own odor like traditional deodorants. It does not cause disgust in people 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.
