Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a deodorizing agent and a method for producing the same.
Methods for deodorizing or deodorizing include, for example, methods of masking bad odors with aromatic substances such as camphra oil, methods of oxidizing and decomposing odorous substances with oxidizing agents such as potassium permanganate, making them odorless, zinc sulfate, sulfuric acid, etc. A method of fixing bad odors such as ammonia and hydrogen sulfide with metal salts such as aluminum and iron sulfate, and neutralizing odorous substances with neutralizing agents such as salts, nitric acid, sodium hydroxide, and sodium carbonate to make them odorless. There are known methods for adsorbing bad odors using activated carbon.

However, among these methods, the method using a masking agent has the disadvantage of causing discomfort in places where one stays for a long period of time, and the other methods using oxidative decomposition, neutralization, immobilization, or adsorption have the disadvantage that they are not effective against odorous substances. It has a high selectivity and deodorizes substances such as ammonia and amines well, but it has disadvantages such as being ineffective against sulfur compounds such as mercaptans, or vice versa. Another drawback was that the drugs used for that purpose were expensive.

In response to the above, the present inventors have conducted various studies and found that a substance that can be thermally extracted from fresh leaves or dried products of plants of the Camellia family, Lauraceae family, etc. using an alcohol-based organic solvent, a ketone-based organic solvent, water, or a mixed solvent thereof. has a deodorizing effect on all kinds of odorous substances, but especially amines,
The present invention was completed by discovering that it has a remarkable deodorizing effect on mercaptan-based organic substances.

In the present invention, the extraction raw materials include, for example, sasanqua sasanqua,
Camellia family plants such as camellia, sakaki, hisakaki, laurel, cinnamon,
Examples include fresh leaves of plants of the Lauraceae family such as camphor tree, or dried products thereof. In particular, fresh leaves of tea plants or dried products thereof are preferred because they are easy to obtain and are highly safe.

In addition, in the case of tea plants, even if it is a decaffeinated extract, there is no problem in extracting the present deodorizing/deodorizing agent.

In the present invention, the solvents used for extracting the active ingredients from the raw materials include, for example, alcohol-based organic solvents such as methanol, ethanol, propatool, and improp-tool, ketone-based organic solvents such as acetone and methyl ethyl ketone, water, and their like. Examples include mixed solvents, and ethanol and isopropanol are particularly preferred because they have a high extraction rate of the active ingredient and have a strong deodorizing effect.

In order to extract the active ingredient of the deodorizing agent of the present invention from the above-mentioned raw material, it is preferable to add about 4 to 6 parts of solvent 1 to 1 part of the raw material and heat the mixture to the reflux temperature of the solvent.

Although the extraction time varies slightly depending on the type of extraction device and raw materials, for example, when using a Soxhlet extraction device, it is preferably about 10 to 20 hours.

In this way, the active ingredients in the raw material are transferred into the solvent and extracted, and by removing the raw material residue by filtration or centrifugation, an extract containing the active ingredients can be obtained.

By removing the solvent from this extract, the active ingredient is obtained as a dark green to greenish brown powder or solid.

In the present invention, when the above-mentioned active ingredient is used as a deodorizing/deodorizing agent, an appropriate dosage form can be adopted depending on the purpose of deodorizing or deodorizing.

For example, when applied to hot water areas that generate bad odors such as toilets, sewage treatment plants, garbage disposal, fish boats, feed factories, livestock stands, etc., the above active ingredients are dissolved in lower alkanols such as methanol, ethanol, or hydrous lower alkanols. It is best to spray the active ingredient in the form of a liquid or aerosol.When deodorizing or removing bad odors from food, drink, or medicine, the active ingredient can be applied as a powder or formed into tablets or granules using a conventional method, and then administered as a powder or in the form of a tablet or granule. It is best to seal it separately in the packaging or storage container of the product or medicine.

In these cases, the required amount of the active ingredient varies depending on the raw material for extraction of the active ingredient, the place of application, the odorous components, etc., but for example, when spraying directly on a hot water area where a bad odor is generated, it is approximately 0% compared to the amount of the odorous substance. About 0.01 to 0.1 part is sufficient, and for example, when separately sealed in a container or storage, about 0.01 to 0.1 part is sufficient based on the amount of odorous substance. .

The deodorizing agent of the present invention has a deodorizing or deodorizing effect on odorous components such as hydrogen sulfide, mercaptan, methyl sulfide, ammonia, and amine compounds, and is also effective against all other types of bad odors. .

Although the mechanism of action of the deodorant/deodorant of the present invention is not clear, it is likely that the active ingredients extracted from fresh leaves or dried products of plants of the Camellia family and Lauraceae family include flavone compounds, Since it contains many unsaturated aldehyde compounds and organic acids (tannic acid, etc.), for example, for mercaptan compounds, addition to flavone compounds and unsaturated aldehydes, ammonia, and amine compounds This is presumed to be based on reactions to aldehydes, etc., and neutralization with the above-mentioned organic acids.

It is also assumed that deodorizing and deodorizing effects occur due to the presence of substances that envelop the malodorous components mentioned above and suppress their release into the atmosphere.
