Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for producing a deodorant obtained from plant extract components.

Prior Art Today, bad odor events are extremely complex and come from a wide variety of sources, from factories, restaurants, and sewage treatment plants to homes such as refrigerators, toilets, and even cars. In most cases, the odor generated is a mixture of various trace components. Conventionally, methods for removing foreign odors and malodors include methods of physically adsorbing odor components onto porous surfaces and removing them;
Methods of removing these substances through adsorption or reaction through chemical bonds, and methods of using substances with a stronger aroma than the malodorous components to make the malodor less intense are known.

However, methods using physical adsorption have the disadvantage that the adsorbent itself reaches a saturated state in a short period of time, while methods using chemical adsorption have a high selectivity for malodorous substances and are used in actual malodor events consisting of complex odors. The disadvantage is that it is not suitable for

The masking method has the disadvantage that the aromatic component that masks the malodor event does not necessarily suit the taste of the user, or that if the masking agent has a strong odor, it may even cause discomfort.

<Problems to be Solved by the Invention> The present invention was invented to solve the above-mentioned problems, and the deodorant component itself has a weak odor and is effective against various odorous substances. The object of the present invention is to provide a deodorant that is particularly effective against ammonia, trimethylamine, and methylmercabutane.

Means for Solving the Problems> That is, the present invention extracts living organisms or dried products of leaves or petals of plants of the family Saxifrage family, specifically plants of the genus Hydrangea, using a polar solvent, and effectively uses the obtained extract. This is a method for producing a deodorant as an ingredient.

Examples of polar solvents include hydrophilic solvents such as water, lower alcohols, and ketones. Preferably, the polar solvents are a mixture. For example, extraction may be performed using a mixture of water and ethanol at a ratio of 1:4. give

If necessary, the extract is centrifuged to remove insoluble matter and the solvent is also removed to obtain an effective deodorizing component.

The plants of the Saxifrage family mentioned here include the genus Saxifrage, the genus Arachigusa, the genus Porphyra, the genus Deutschia, the genus Gooseberry, and the genus Hydrangea. Among them, species of the genus hydrangea that are relatively easy to obtain include hydrangea, little hydrangea, hydrangea, rosy hydrangea, mountain hydrangea, and red hydrangea.

The deodorizing substance is obtained by removing moisture from the raw material in an oven set at 60°C, drying it, and then powdering it using a mixer.

The above solvent was added at a ratio of approximately 20 m2 to 1 g of this powder, and after hot extraction at 60°C for 1 hour,
Perform a 24 hour room temperature extraction. After filtration, the same solvent is further added to the residue, followed by hot extraction at 60°C for 1 hour, followed by separate filtration, and the filtrate is combined with the previously separated extract and concentrated using a rotary evaporator or the like. After the concentrated solution is centrifuged to separate solids and dissolved components, only the dissolved components are diluted with water to a constant concentration in a volumetric flask to obtain a deodorizing solution. Further, this deodorizing liquid is dried under reduced pressure to obtain a solid deodorizing product, which is used for actual deodorizing.

<Effect> This solid substance itself has very little odor, so it does not cause discomfort when used with conventional masking agents, and is effective in removing various bad odors, especially ammonia,
Its effect is superior to 1-limethylamine and methylmercabutane. Moreover, this raw material is also easily available at low cost, and the operation for obtaining the deodorizing component is simple. It is estimated that the deodorizing mechanism is a complex combination of neutralization, decomposition, redox, complex formation, and clathration with polyphenols, amino acids, chlorophyll, etc. in a multi-component hybrid system of plant extract components. has been done. The present invention will be explained in more detail with reference to Examples below.

<Example 1> 6 g of dried hydrangea leaf powder and 150 g of a mixed solvent of water:ethanol-1:4 were placed in an Erlenmeyer flask and heated at 60°C.
After a 1-hour hot water bath, extraction was performed at room temperature for 15 hours. The extract was separated by suction filtration, and the residue was again
The same solvent as used for wild goose was added and re-extraction was carried out at 60°C for 1 hour.

After suction filtration, the filtrate was combined with the previous extract, concentrated using a rotary evaporator, then centrifuged to separate the solids, and the liquid was collected in a volumetric flask for 10
It was diluted with water to 0 mR to obtain a deodorizing solution. 5 ml of this was dried under reduced pressure to obtain about 58 mg of solid deodorant.

Example 2 2 g of dried hydrangea petal powder was treated in the same manner as in Example 1 to obtain a 100% deodorizing liquid. Of these, five components were dried under reduced pressure to obtain about 37 mg of solid deodorant.

<Example 3> The deodorizing effect of ammonia on the deodorant liquids obtained in Examples 1 and 2 was measured.

Test method A solid deodorizing product obtained by drying and solidifying 5d of deodorizing liquid and about 2 g of ammonia gas were placed in a 160 ml glass bottle and the bottle was tightly stoppered. A blank sample without solid deodorant was also prepared. This was stored in a thermostat set at 20°C, and after 5 hours of treatment, the amount of gas remaining in each bottle was measured using a gas chromatograph, and the amount of gas in the bottle containing the deodorant was measured ( Determine a) and the loss of gas in the blank bottle, i.e. the amount adsorbed on the glassware wall (b),
The amount of gas deodorized by the deodorant itself was calculated from a-b.

From this calculation result, the amount of gas adsorption of the deodorant calculated per 1 g of dry matter was determined and shown in FIG. For comparison, the gas adsorption amounts of other plant components obtained using the same extraction method are also listed.

<Example 4> The deodorizing effect of trimethylamine on the deodorant liquids obtained in Examples 1 and 2 was measured.

Test method The same treatments and measurements as in Example 1 were carried out using about 2 g of trimethylamine gas. Calculate the results in the same way, dry matter 1
Figure 2 shows the gas adsorption amount of the deodorant in terms of units per gram. For comparison, the gas adsorption amounts of other plant components obtained using the same extraction method are also listed.

<Example 5> Regarding the deodorizing liquid obtained in Example 2, the deodorizing effect of methyl mercabutane was measured.

Test method The same treatment and measurement as in Example 1 were carried out using about 2 g of methyl mercaptan gas. Calculate the results in the same way, dry matter 1
Figure 3 shows the gas adsorption amount of the deodorant in terms of grams. For comparison, the gas adsorption amounts of other plant components obtained using the same extraction method are also listed.

<Effects of the Invention> As described above, the deodorant obtained by the present invention has raw materials that are inexpensive and easy to obtain, a manufacturing method that is simple, and is highly effective. Since the deodorant itself has an extremely low odor, it can be effective in a variety of fields without causing discomfort. In addition, there have been inventions of deodorants that use plant ingredients, such as those that use extracts from plants such as Camellia and Pinaceae, but it is clear from the graphs in the drawings that their effects are superior to those of other deodorants. Understandably, it can be said to be an extremely effective and practical deodorant.
