Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] [This invention relates to a method for producing a deodorizer for purifying and deodorizing air.

[Background technology]

Generally, the sources of bad odors and strange odors are factory smoke and waste liquid, cigarettes, urine and urine, kitchen waste, etc., and there are a wide variety of types of bad odors and strange odors. In particular, in homes, rooms are often kept closed when air-conditioning 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.

■ Arbitrary deodorization method: A method of masking bad odors and foreign odors using aromatic substances (fragrant essential oils, etc.).

■ Physical deodorization methods: Diluting and removing bad 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 contact.

■ 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, direct combustion method or oxidation method using oxidizing agents such as ozone or potassium permanganate.

■ Biological deodorization method: A method that reduces and kills microorganisms that cause spoilage, prevents spoilage, and prevents the occurrence of bad odors.

Other methods include deodorizing using wood vinegar obtained by carbonizing wood.

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, aromatic substances have a limited ability to remove odorous substances, and it is difficult to maintain a balance between scents and odors.Furthermore, people have different tastes in the scent of deodorants, and there are times when there is an aversion window. It is difficult to say that it is a general deodorizing method. The physical method (2) is widely used, but in addition to problems such as the need for equipment and fluctuations in room temperature, the adsorption effect for bad odors and off-flavor components is not sustainable, and it does not reach a saturated state. If so,
There is a problem in that it releases odor components. In addition, in chemical deodorization method (2), it is extremely difficult to select substances that react effectively with a wide variety of malodorous components. Furthermore, it is not common because the chemicals used must be handled with care and the chemicals may deteriorate in the air. Furthermore, the biological deodorization method described in (■) is not suitable for use for the purpose of removing odors in the atmosphere, requires equipment, and has the disadvantages of slow onset of effects. The current situation is that each law has its advantages and disadvantages.

[Purpose of the invention]

An object of the present invention is to provide a method for producing a deodorant that does not have the above-mentioned conventional problems.

[Disclosure of the invention]

In order to achieve the above object, the inventors devised the use of active ingredients in plants as a deodorizer that is odorless and safe, and does not require large-scale equipment.
In particular, we have devised a method for producing a deodorant in which deodorizing components are extracted from plants of the genus Oleaceae of the Oleaceae family, such as Osmanthus oleracea, Osmanthus oleracea, Holly osmanthus, Holly osmanthus, and Elephant osmanthus.

That is, the present invention provides a deodorizing effective ingredient that is obtained by extracting at least one of the leaves and trunk of a plant of the genus Oleaceae of the family Oleaceae using an extraction solvent consisting of at least one of a hydrophilic organic solvent and water. The gist is the manufacturing method of odorants.

This will be explained in detail below.

The raw materials for this invention include leaves and tree trunks (including bark and rhizomes) of plants of the genus Oleaceae of the Oleaceae family, such as Osmanthus, Osmanthus, Holly, Holly Osmanthus, and Osmanthus
can be mentioned.

The extraction method from plants is to add hydrophilic organic solvents such as water, alcohols such as ethanol and methanol, and ketones such as methyl ethyl ketone and acetone to the raw material plants mentioned above, and deodorize using a Soxhlet extractor. Heat extract the ingredients. This extraction operation may be performed using a mixed solvent of these hydrophilic organic solvents and water. Extraction is usually carried out by thermal extraction. For example, when water is used as the extraction solvent, 6
It is carried out at a temperature in the range of 0 to 80°C, but is not limited thereto.

Note that the extraction is not a one-step extraction like this, but a hydrophobic organic solvent, such as hexane, is used as necessary.

In some cases, petroleum ether or the like is used to elute and remove odor components from the raw material plants in advance. Alternatively, a single steam vapor method may be used.

The extract thus obtained can be used as is or after removing the solvent. The method is not limited. For example, methods that are less susceptible to thermal denaturation, such as vacuum drying, hot air drying, and spray drying, are used. This is further diluted with water or ethanol to make a deodorant product.

The porous material may be impregnated with the extract before removing the solvent from the extract. This will increase the deodorizing effect. Examples of porous materials include activated carbon, silica gel, zeolite nonwoven fabric, and clay minerals such as montmorillonite. Those impregnated with porous materials are used as is.

Next, an explanation will be given based on an example.

(Example 1) 1 kg of Osmanthus leaves (including small tricks) was heated in a warm bath using a mixed solvent of water and ethanol (volume ratio: water:ethanol = 50).
:50) 6β was added and heat extracted. The obtained extract was dried using a spray dryer to obtain a deodorant.

(Example 2) Grind 100g of Holly Oleander leaves and add 20g of acetone.
It was refluxed at 0 m7 and then filtered. The filtrate was vacuum dried to obtain a deodorizer.

(Example 3) 100 g of holly leaves were immersed in 600 ml of water, and extracted while heating with an immersion heater. Examples 1 to 3 above, in which deodorants were obtained by removing the solvent from the extract by vacuum drying
In order to examine the deodorizing effect of the deodorant obtained, the following test was conducted. That is, ammonia, hydrogen sulfide, and trimethylamine correspond to 5 on the 6-level odor intensity scale in Table 1 below.

Put 12μ2 each of ethyl mercaptan and pyridine into a 200 m Erlenmeyer flask with a stopper, and add 12μ2 of each of the above deodorants.
A wt% solution (solvent: water:ethanol=1=1) was added in equal amounts. Ten panelists (5 men, 9 women) were asked to sniff the inside of the flask, and the results were as shown in Table 1 below.
The participants were asked to rate the odor based on the odor intensity of each stage. The results are shown in Table 2. For comparison, the odor was also evaluated for samples to which no deodorant was added.

As shown in the table, the deodorants of Examples 1 to 3 were highly effective.

(Example 4) 100g of Osmanthus leaves in water:ethanol = 50:5
The deodorant was extracted with a mixed solvent of 0, impregnated with activated carbon, and dried with hot air at 80°C to obtain a deodorant. This is attached to a sheet of urethane and suspended in a 2.5 d acrylic box.
Methyl mercaptan was added so that the odor concentration was 10 ppm, and the odor concentration was tracked over time.
The odor concentration became 0 within minutes.

(Example 5) 5 kg of oleander leaves were extracted with 301 ml of water, impregnated with 10 kg of montmorillonite, and dried to obtain a deodorant. When we asked monitors (20 household housewives) to spray the deodorizer on kitchen waste in each household, 1.
Four people reported that the odor became odorless, and the remaining six people reported that the odor was almost no longer bothersome to them.

〔Effect of the invention〕

Since the method for producing a deodorant according to the present invention is configured as described above, it is possible to safely and easily obtain a highly effective deodorant that is odorless in itself, without causing the above-mentioned conventional problems. .

That is, since the obtained deodorant itself is odorless, it does not cause disgust in people due to its own odor, unlike the conventional deodorants. In addition, since the raw material is a widely available plant, it can be obtained at low cost and does not require large-scale equipment for deodorization. Moreover, it can deal with a wide range of bad odors such as ammonia, hydrogen sulfide, and amines, so it can effectively deal with bad odors in factories, homes, and even toilets. Since it never becomes saturated, its lifespan is long.
