Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] This invention relates to a method for producing a deodorant that does not eliminate bad odors and foreign odors.

[Background technology]

In general, the sources of bad odors and strange odors are factory smoke, waste liquid, cigarettes, deep floors, kitchen waste, etc., and there are a wide variety of types of bad odors and strange odors.
Physical methods and chemical methods have been adopted as methods for eliminating such malodors and foreign odors. Physical methods include a water washing method, a cooling method, an adsorption method, and the like. However, the washing method and the cooling method require a large amount of water and large-scale equipment, so they cannot be called general methods. The adsorption method uses the adsorption power of activated carbon etc. to adsorb and deodorize bad odors and off-flavor components.
The problem is that after adsorption of malodor components, the malodor and malodor components are released back from the activated carbon and the like. Chemical methods include chemical treatment methods, masking methods, and the like. Chemical treatment methods deodorize by acid-alkali cleaning, etc., but the target malodorous components are limited, the chemicals used must be handled with care, and large-scale equipment is required.

The masking method is a method of deodorizing by masking bad odors and foreign odors with the scent of the deodorant itself.

However, in this case, it is difficult to say that this is a general method because people have preferences for the scent of the deodorant itself, and some people may feel disgusted by the scent.

[Purpose of the invention]

The purpose of this invention is to provide a method for producing an inexpensive deodorant that is itself odorless, does not require large-scale equipment for deodorization, and can eliminate a wide range of bad odors. .

[Disclosure of the invention]

This invention provides a deodorizer characterized in that at least one of the leaves and buds of a tree belonging to the genus Clas in the Rosaceae family is subjected to a treatment to remove aroma components, and then subjected to a treatment to separate the effective deodorizing component to obtain a deodorizer. The gist is the manufacturing method.

'Next, this invention will be explained in detail.

The inventors conducted a series of studies to resolve the various drawbacks of conventional deodorizing methods, and as a result, they focused on the leaves and buds of trees of the Rosaceae genus, which are widely available and inexpensive. By extracting and removing the characteristic aroma with a hydrophobic organic solvent and extracting the residue with a hydrophilic organic solvent, the product itself is odorless, can instantly respond to a wide range of odors, and is highly effective in deodorizing. The inventors have discovered that it is possible to obtain a deodorizing agent that does not require extensive equipment and is also inexpensive, and have thus arrived at this invention.

The tree to be extracted in this invention is a tree of the genus Prunus in the Rosaceae family. In this invention, the leaves of these trees (fresh leaves,
Dried leaves) and buds (fresh buds, dried buds) are used as raw materials.

The hydrophobic organic solvent used to remove the above-mentioned aroma components specific to the raw materials may be any solvent as long as it can remove the aroma components. For example, petroleum ether, petroleum benzene, n
-Hexane, cyclohexane, benzene, chloroform, and carbon tetrachloride, which may be used alone or in combination.

Examples of the hydrophilic organic solvent include alcohols such as methanol and ethanol, and ketones such as acetone and methyl ethyl ketone. These solvents may be used alone or in combination. Furthermore, such a hydrophilic organic solvent and water may be mixed and this mixed solvent may be used.

Extraction with a hydrophobic organic solvent and extraction with a hydrophilic organic solvent described above are usually carried out by thermal extraction, but are not limited thereto.

The extract obtained by the above extraction is usually concentrated. This concentration is not particularly limited.

Any method may be used as long as the above hydrophilic organic solvent etc. can be removed. For example, a vacuum dryer, an evaporator, etc. are used.

The deodorant thus obtained is usually diluted with water, ethanol, or the like to produce a deodorant product.

Since this deodorant itself has no odor, it does not cause discomfort due to its own odor, unlike deodorants used in conventional masking methods. In addition, this deodorizer has a wide range of applications as it effectively acts on all kinds of odors, from the odors of factory wastewater to the odors of kitchen waste in the home and the odors of frozen fields. You will be able to get a deodorizing effect. Furthermore, this deodorizer has the advantage of being able to instantly deodorize, does not require large-scale equipment for deodorization, and is inexpensive.

Next, the present invention will be explained in detail based on examples.

[Example 1] 50 g of fresh wild cherry leaves and 50 ml of n-hexane were placed in a Soxhlet extractor and refluxed to remove components other than the active components (fragrant components). Next, n-hexane was removed, and 50 mA of ethanol was charged into a Soxhlet extractor and refluxed. Then, the raw material residue was filtered out from the obtained ethanol extract, and the filtrate was concentrated to dryness under reduced pressure to obtain 6.2 g of a solid (deodorant).

In order to examine the deodorizing effect of this deodorant, the following test was conducted. That is, 200mj of trimethylamine!
Add 1 g of deodorant aqueous solution 1 to 1 g of water in 1 g of water to 1 g of deodorizer in 1 g of water.
m7! was added to the odor, and six Nognerers A to F were asked to examine the odor condition based on six levels of odor intensity from 1 to 5 minutes after the addition of the aqueous deodorant solution. The results are shown in Table 1.

In Table 1, 0...Odorless, ■...Emergency G
Slightly good, 2... Slight odor, 3... Easily smells 1. 4... The odor is strong, 5... The odor is very strong (G).

From Table 1, it can be seen that the aqueous deodorant solution of Example 1 quickly and almost completely eliminates the bad odor of trimethylamine.

[Examples 2 to 4] 50 g of fresh plum leaves and 50 ml of Hensen's were placed in a Soxhlet extractor and refluxed to remove components other than the active ingredients. Next, n-hexane was removed, and 50 mji of a polar solution (water-methanol system) having the composition shown in Table 2 was charged into a Soxhlet extractor and refluxed.

Then, the raw material residue was filtered from the obtained extract, and the filtrate was concentrated to dryness under reduced pressure to obtain a solid (deodorant).

In order to examine the deodorizing effect of the obtained deodorant, the following test was conducted. In other words, put 5 mj of the malodorous substances shown in Table 3 into an Erlenmeyer flask! Add 1g of the above deodorant to it
Add 9ml of deodorant water dissolved in 1ml of water and add 5ml of deodorant water dissolved in it.
Minutes later, the six panelists were asked to examine the odor condition based on the six levels of odor intensity as described above, and the average value was calculated as the third
Shown in the table.

Table 3 shows that the deodorant of the present invention can effectively deodorize a wide range of malodorous substances.

〔Effect of the invention〕

As described above, the present invention provides a method for obtaining a deodorizer by subjecting at least one of the leaves and buds of a tree belonging to the Rosaceae family, the genus Cura, to a treatment to remove aroma components, and then to a treatment to separate the effective deodorizing component. An extremely effective product that is odorless and can quickly deodorize a wide range of odors! i) It will be possible to produce odorants. In particular, this deodorant is inexpensive because it is made from plants, and is odorless itself, so it does not cause disgust in people due to its own odor, unlike conventional deodorants. Moreover, it has the advantage that large-scale equipment is not required for deodorization.
