Description

[Detailed description of the invention]

[Industrial Application Field] This invention relates to a deodorant that eliminates bad odors and foreign odors. [Prior Art] Generally, the sources of bad odors and strange odors are factory smoke, waste liquid, cigarettes, human waste, kitchen waste, etc., and there are many 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. Until now, physical methods and scientific methods have been adopted as methods for eliminating such bad odors and foreign odors. Physical methods include a water washing method, a cooling method, and an adsorption method. 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. Adsorption methods that utilize the adsorption power of activated carbon to adsorb and deodorize malodors and off-flavor components have the disadvantage that after adsorption of the malodor and off-odor components, the malodor and off-odor components are released back from the activated carbon and the like. Scientific methods include combustion method, chemical treatment method,
There is a masking method. However, the combustion method requires large-scale equipment and increases running costs, so it is not common. Chemical treatment methods deodorize by acid-alkali cleaning, etc., but the target malodorous components are limited and the chemicals used must be handled with care. The masking method is a method mainly practiced in households, and 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 feel disgusted by the scent. [Problems to be Solved by the Invention] The present invention provides an inexpensive deodorant that is substantially odorless, does not require large-scale equipment for deodorization, and can eliminate a wide range of bad odors. This is the issue to be addressed. [Means for Solving the Problems] In order to solve the above problems, the deodorant according to the present invention contains as an active ingredient an extract obtained by subjecting a Pinaceae plant to an extraction operation. Next, this invention will be explained in detail. The inventors have conducted a series of studies over many years in order to eliminate the various drawbacks of conventional deodorants. As a result, we focused on the leaves and tree trunks of inexpensive Pinaceae plants that are widely available in the world, and by applying extraction operations to them, we found that they are odorless themselves and can instantly respond to a wide range of odors. We have discovered that a safe and inexpensive deodorizing active ingredient can be obtained, and have arrived at this invention. The raw materials for obtaining the active ingredients of the deodorant according to the present invention include Pinaceae plants, namely fir,
Fir genus such as Japanese fir and fir, fir genus Himalayan genus, genus Larch, genus Picea acanthus, pine spruce, genus Picea such as spruce, Pinus fulva, Pinus fulva,
Examples include leaves and tree trunks (including bark and rhizomes) of the genus Pinus such as Japanese pine, Japanese pine, Japanese black pine, and Japanese pine, as well as the genus Hemlock and hemlock. In order to obtain the active ingredients of the deodorant according to the present invention, the above-mentioned raw materials are subjected to an extraction operation. This extraction operation is usually performed by subjecting these raw materials to thermal extraction using a hydrophilic organic solvent or water as a solvent, but is not limited to thermal extraction. Since Pinaceae plants have a faint aroma, if it is necessary to remove this aroma, an extraction operation using a hydrophobic organic solvent is performed prior to the above extraction, and then the extraction residue is treated with a hydrophilic solvent. It is preferable to carry out main extraction using a neutral organic solvent or water as a solvent. Examples of the hydrophilic organic solvent used in this extraction operation include alcohols such as methanol and ethanol, and ketones such as acetone and methyl ethyl ketone. These hydrophilic organic solvents are
They may be used alone or in combination.
Furthermore, it may be used in combination with water. Also,
Examples of hydrophobic organic solvents include paraffinic hydrocarbons such as n-hexane, cycloparaffinic hydrocarbons, aromatic hydrocarbons such as benzene, and halogenated hydrocarbons such as chloroform. used. For the extract obtained by the above extraction,
Usually concentrated. This concentration is not particularly limited. 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. [Example] Next, the present invention will be explained in detail based on an example. -Example 1- 50g of fir leaves were extracted using a Soxhlet extractor.
Heat extraction was performed with n-hexane to elute and remove components other than the active components (fragrant components). Next, 200 ml of a mixed solution of water and ethanol (water:ethanol = 50:50 [volume ratio]) was added and heat extracted, and the solvent was removed from the resulting extract by vacuum drying, etc., and the deodorant was added. Obtained. -Example 2- 100g of dried red pine wood was crushed and refluxed with benzene. The extraction residue was then refluxed with 200 ml of acetone and then filtered. Next, the obtained filtrate was subjected to vacuum drying or the like to remove the solvent, thereby obtaining a deodorant. -Examples 3 to 5- Using the raw materials shown in Table 1 instead of the dried wood of fir, leaves, and red pine, extraction was performed under the conditions shown in the table, and the solvent was removed from the extract to create a deodorant. I got it.

[Table] In order to examine the deodorizing effects of the deodorants obtained in Examples 1 and 3 to 5 above, the following tests were conducted. That is, add 12μ of deodorizing ammonia, hydrogen sulfide, trimethylamine, ethyl mercaptan, and pyridine corresponding to deodorizing strength 5 below to a 200ml Erlenmeyer flask with a stopper, and add 1wt of deodorant to it.
% aqueous solution was added in the same amount, and the odor condition was examined by 10 panelists (5 men, 5 women) based on 6 levels of odor intensity, and the results are shown in Table 2. In addition, table -
In 2, 0...Odorless, 1...Very faint odor, 2...Slight odor, 3...Easily sensed odor, 4...Strong odor, 5...Very strong odor. It shows. Moreover, the comparative example shows the degree of odor when no deodorant is added.

[Table] According to the table above, the deodorants of Examples 1, 3 and 4 are:
It can be seen that all of them can almost completely eliminate bad odors. In addition, when the deodorizer obtained in Example 2 was made into a 5wt% aqueous solution and installed in the individual changing lockers of 20 people for 3 weeks, 18 people reported that after installing the deodorizer, the bad odor inside the locker was I felt it had disappeared. -Examples 6 to 9- The deodorizing effects were examined in the same manner as in Table 2 when extracts obtained from the raw materials shown in Table 3 were used as deodorizing active ingredients. The results are shown in Table 3.

〔Effect of the invention〕

As described above, the deodorant according to the present invention obtains the active ingredient by extracting the Pinaceae plant, so it is odorless itself and is an extremely effective deodorizer that can quickly deodorize a wide range of bad odors. It has become an effective deodorizer, and has the advantages of being able to deodorize instantly, not requiring large-scale equipment for deodorization, and being inexpensive and safe. ing. That is, since this deodorant itself is substantially odorless, it does not cause disgust or discomfort in people due to its own odor, unlike deodorants used in conventional masking methods. In addition, since the raw material is a plant, it is cheap and safe, and since the deodorizing active ingredient is obtained through an extraction operation, large-scale manufacturing equipment is not required. Moreover, it can deal with a wide range of bad odors such as ammonia, hydrogen sulfide, amines, and pyridines, so it can effectively deal with a wide range of bad odors, from the bad odors of factories and factory wastewater to the bad odors of household kitchen waste and toilets. In addition, unlike adsorption type deodorants, it does not become saturated, so its lifespan is long and its deodorant action can be exerted for a long time.
