Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a deodorant having deodorant or deodorant properties.

[0002]

2. Description of the Related Art It is known that persimmon extract, green tea extract and the like each have a deodorizing effect. The deodorizing mechanism of these is that polyphenols and tannins present in persimmon extract, green tea extract, etc. can exert a deodorizing effect by neutralizing, oxidizing / reducing, and inclusion reaction with malodorous substances. It was supposed.

However, persimmon extract, green tea extract, etc. have limitations such that they cannot be blended in a high concentration in a product because of their problems of unique color, odor (fermentation odor, etc.) and precipitation due to polymerization reaction. It was Therefore, in order to eliminate these drawbacks, there is a demand for a stronger deodorant that is effective even if it is blended in a concentration as low as possible.

The present invention has been made in view of the above problems existing in the prior art, and its object is to obtain food, bad breath, body odor and other bad odors even at low concentration. Another object of the present invention is to provide a deodorant having excellent safety that can effectively deodorize or deodorize the above.

[0005]

The deodorant of the present invention is characterized by containing persimmon fruit liquid or its solidified product or persimmon fruit extract and a water-soluble extract of green tea as main components.

The deodorant of the present invention may contain, for example, a physiologically harmless excipient, and persimmon fruit liquid or a solidified product thereof or a persimmon fruit extract and a water-soluble extract of green tea. It may be supported on a physiologically harmless carrier.

As the persimmon fruit liquid or its solidified product or persimmon fruit extract, persimmon fruit juice or fruit juice, its concentrated liquid or solidified product, or solid or liquid extract can be used.

The persimmon fruit liquid or its solidified product or persimmon fruit extract is preferably the fruit liquid of immature persimmon or astringent persimmon or its solidified product or fruit extract (claim 2).

As the water-soluble extract of green tea, a solid or liquid water-soluble extract of tea leaves, dried products thereof, or those which have been heat-treated by steam or roasting can be used.

The persimmon fruit liquid or its solidified product or the persimmon fruit extract can be obtained, for example, by dehydration and concentration under reduced pressure of a substance from which sugars have been removed by natural fermentation of juicy persimmon juice or astringent persimmon juice.

The water-soluble extract of green tea can be obtained, for example, by extraction from dried leaves of Cyanoki [Thea sinesis L. (Theaceae)] under conditions capable of extracting a water-soluble component. More specifically, for example, using an aqueous solution in which an aqueous solvent such as ethanol or glycerin is dissolved, the extract extracted from the dried cypress leaves under heating (about 60 ° C.) is dehydrated and concentrated under reduced pressure. Can be obtained by

The deodorant of the present invention may also be produced by mixing persimmon fruit liquid or persimmon fruit extract, and water-soluble extract of green tea liquid dehydrated and concentrated or powdered. Alternatively, it can be prepared by performing dehydration concentration before concentration or after mixing in the dehydration concentration process.

The ratio of persimmon fruit liquid or its solidified product or persimmon fruit extract to the water-soluble extract of green tea is, for example, 1 part by weight of the water-soluble extract of green tea (as solid content) or persimmon fruit liquid or The solid or persimmon fruit extract 1 to 10
It can be part by weight (as solid content), but is not limited thereto. Both are preferably present in a uniformly mixed state.

In the deodorant of the present invention, persimmon fruit liquid or a solidified product thereof or a persimmon fruit extract is combined with a water-soluble extract of green tea, whereby the persimmon extract or the green tea extract is compared to the case of using the persimmon extract alone. However, the deodorizing or deodorizing effect is dramatically enhanced, and the peculiar odors and fermented odors of persimmon and green tea are effectively suppressed by the interaction of the two in combination.

Although the reason for this is unknown, it is likely that condensed tannins contained in persimmons, catechins contained in green tea,
It is considered that hydrolyzed tannin and the like interact with each other to compensate for their respective disadvantages and to exhibit a synergistic effect. Furthermore, since pyrogallol contained in persimmon and catechin contained in green tea have an antibacterial action, they are considered to be effective against the odor of spoilage caused by secondary contamination by microorganisms (bacteria, fungi, etc.).

[0016]

EFFECTS OF THE INVENTION The deodorant of the present invention has a very high deodorizing or deodorizing effect as compared with the case of using persimmon extract or green tea extract alone, and even in low concentration, foods, halitosis, body odor and other malodorous And the like can effectively deodorize or deodorize, and the peculiar odors and fermentation odors of persimmon and green tea can be effectively suppressed.

[0017]

[Examples] 800 g of unripe persimmon was cut into small pieces and 200 g of dried camphor leaves (green tea) was cut into small pieces.
After immersing in 1000 g of 1% glycerin aqueous solution at 50 ° C. for 24 hours to elute the components of pulp and in-leaf tissue, it was filtered to remove the solid content, and further stored for 6 months in a hermetically sealed state by fermentation. The sugar was removed. Then, it dehydrated under reduced pressure and obtained 300 g of concentrated extract liquids. Further, similarly, dehydration was performed under reduced pressure to obtain 60 g of concentrated powder.

For comparison, 800 g of unripe persimmon and 200 g of camphor leaves (green tea) were treated in the same manner to prepare respective extracts.

Next, the results of the deodorizing power test will be shown. Test Example 1 1 g of an aqueous solution containing 3% by weight of a concentrated extract solution as the deodorant of the present invention was poured into an Erlenmeyer flask. Regarding an aqueous solution containing 1% by weight of the concentrated extract of the present invention, an aqueous solution containing 5% by weight of the persimmon extract, and an aqueous solution containing 5% by weight of the green tea extract, 1 g of each was placed in a separate Erlenmeyer flask. Injected.

Then, 500 ml of ammonia (750 ppm) was injected into each of the four Erlenmeyer flasks and sealed.

Trimethylamine (80 ppm), iso-
Valeric acid (40 ppm), hydrogen sulfide (100 ppm), and mercaptan (60 ppm) were similarly sealed in the Erlenmeyer flask.

After 30 minutes, residual amounts of ammonia, trimethylamine, iso-valeric acid, hydrogen sulfide, and mercaptan were measured by the Kitagawa detection tube method, and the deodorizing rate of each was obtained. The results are shown in Tables 1 to 3.

[0025]

[Table 3] As shown in Tables 1 to 3, the persimmon extract and the green tea extract alone have a relatively mild deodorizing effect, but in the case of the deodorant of the present invention, the deodorizing effect is remarkably excellent as compared with them. It has an odor effect. However, the deodorant ratio of the present deodorant of the present invention is superior to the sum of the deodorant ratio of the 5 wt% persimmon extract and the deodorant ratio of 5 wt% green tea extract. It can be seen that the odorant has a synergistic effect. Test Example 2 In the subject group A (5 persons, 3 males, 2 females), the garlic extract containing 1% by weight of the concentrated extract solution as the deodorant of the present invention was added to the subject group B (5 persons, For 3 males and 2 females, the garlic extract containing 5% by weight of persimmon extract and green tea extract was added to the control group (5 males, 3 males).
Garlic extract alone was given to each of the two (1 female, 2 female), and 15 hours later, the degree of deodorization was evaluated by the 6 panelists in the following 6 stages. Garlic extract is
A suspension of 0.3 g of garlic in 100 ml of water was used. The results are shown in Table 4.

0 ......... No odor 1 ... No odor but garlic odor is not distinguishable 2 ・ ・ ・ Garlic odor is slightly distinguishable 3 ... ・ Light to medium garlic odor 4 ・ ・ ・ ・ Strong garlic odor 5 ・ ・ ・ ・ ・ ・ Strong garlic odor

[0027]

[Table 4] The result of this sensory test shows that the deodorant of the present invention can almost completely deodorize the garlic odor, which was conventionally difficult to deodorize, even at a low concentration.

By adding the deodorant of the present invention, it is possible to provide a deodorant product having a long-lasting effect. Examples will be given below, but of course the present invention is not limited thereto. Example 1 Deodorant Granules Concentrated powder as the deodorant of the present invention 3.0% by weight Sodium fumarate 5.0% by weight Orange fiber 3.0% by weight Sorbitol 20.0% by weight Dextrin 68.9% by weight Perfume 0.1 wt% An appropriate amount of water was added to the above composition to give granules by a conventional method.

The product can be used, for example, to suppress bad breath, stool odor, and the like. Example 2 Deodorant lotion Concentrated extract solution as deodorant of the present invention 5.0% by weight 1,3-butylene glycol 2.0% by weight Ethanol 10.0% by weight Cornflower extract 0.5% by weight Methylparaben 0. 1% by weight Purified water 82.4% by weight This lotion can be used, for example, to suppress body odor, cigarette odor, etc. due to sweat or other causes.
