Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a natural deodorant which can be used in the fields of foods, cosmetics, pet foods, sanitary goods and the like.

[0002]

2. Description of the Related Art Conventionally, as means for preventing the generation of unpleasant odors or eliminating the generated unpleasant odors, a method of masking unpleasant odors with an aromatic substance, neutralization, oxidation, There has been a method of deodorizing by decomposition or other chemical reaction, or fixing by adsorbing on an adsorbent such as activated carbon.

[0003] For the purpose of preventing bad breath, improving the flavor of food and drink, and preventing the odor of excrement of pets, the deodorant that can be added to foods, feeds, feeds, oral preparations, etc., is used as a highly safe plant extract. The required research has been promoted, and as a result, green tea extract
No. 8-18098), a deodorant containing an oolong tea extract, a vulgaris extract, a persimmon tannin, a soybean / cereal extract, a spice extract, a mushroom extract and the like as active ingredients has been proposed.

[0004] However, these conventional plant extract-based deodorants not only have an insufficient effect of use, but also have unique smells, bitterness, astringency, etc., and when added in a sufficient amount to foods and oral preparations, they cannot be added. There is a problem that the influence on the flavor and the feeling of use of the product is too large, and it is also generally expensive.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a novel compound which is excellent not only in the effect of use, but also has a small adverse effect on the flavor and feeling of use of the object to be added, and is excellent in terms of safety and cost. It is to provide a deodorant.

[0006]

DISCLOSURE OF THE INVENTION The present invention provides a deodorant containing a horsetail extract as an active ingredient, which has been confirmed by the present inventors for the first time to have an excellent deodorizing action.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Horsetail (Equisetum arvense L.)
Is a plant belonging to the genus Euphorbiaceae, whose spore stem, Tsukushi, has been used for food since ancient times. It has also been used as a folk medicine for diuresis, antitussive, antipyretic, and roundworm control. However, it was not known that the extract had a deodorizing effect.

[0008] The horsetail extract having a deodorizing effect can be obtained from a dried product or a fresh one of the above-ground portion of horsetail.
Fresh products have poor extraction efficiency, and dried products are preferred as extraction raw materials.

Water, a hydrophilic organic solvent, or a mixture thereof can be used as an extraction solvent for obtaining a horsetail extract having a deodorizing effect. Examples of preferred hydrophilic organic solvents for extraction include lower aliphatic alcohols such as methanol and ethanol, and acetone. Extracts obtained using esters and hydrocarbons have almost no deodorizing effect.

The extraction method is not particularly limited, and the extraction can be carried out at room temperature or under reflux with any apparatus. Briefly, an extraction raw material is charged into a treatment tank filled with an extraction solvent, and occasionally stirred to elute a soluble component. After the treatment, the extract is filtered to remove the extraction residue, and the obtained extract is concentrated and dried to obtain an extract having a deodorizing effect.

[0011] This extract has a light brown, slightly fragrant smell peculiar to horsetail and has little astringency and bitterness.
It can be used as it is as a deodorant component.

[0012] The deodorant of the present invention also includes substances other than horsetail extract effective for deodorization, such as green tea, oolong tea, tamarind husk, urajirogashi, ginkgo, perilla, pepper, ginger, clove, ginger, mace, sage and oyster. Leaves, mushrooms, enokitake, bunashimeji, oyster mushroom, nameko, mannentake, red beet, cacao, coffee, parsley, butterbur, sea laver, rosin, dimethylaminosulfonate, Glucosamine, ellagic acid, chlorophyllin derivatives, menthol, peppermint, persimmon juice, chlorhexidine hydrochloride, actizol, Maillard reactants, cyclodextrin, and the like can be contained.

The deodorant of the present invention, which is made from horsetail, is widely used for oral preparations, foods and drinks, etc., as long as it is used as a deodorant, since there is no worry about ingestion into the body. be able to. For example, chewing gum, candy and other confectionery, various dentifrices, mouthwash, troche, mouth freshener, various etiquette products for preventing bad breath, etc. can be blended or attached at any stage of the manufacturing process to prevent bad breath Can be helpful. The preferred content of the deodorant of the present invention in these applications is about 0.01 to 10% by weight as a standard horsetail extract.

The use of the deodorant of the present invention is not limited to the above examples, and other uses, for example, are as follows. A masking agent that eliminates the smell of processed meat and fishery products. Incorporation into deodorant sprays for spraying spaces such as living rooms and toilets. Deodorization treatment mixed into factory exhaust. Deodorant for air purifiers, air conditioners, etc. Deodorization of kitchen garbage. A deodorant for eliminating the smell of manure when used in feed and feed for livestock and pets. Hair tonic for the purpose of deodorizing the scalp and hair,

Deodorizing Test Example 1 A test sample is dissolved in water to prepare an aqueous solution having a concentration of 0.2% by weight. 20ml of this in a 900ml wide jar with lid
And add ammonia water to it. At this time, the injection amount of the ammonia water is calculated so that the concentration in the gas phase of ammonia which is partially vaporized and becomes equilibrium in the bottle becomes 80 ppm when it is assumed that only water is in the bottle. Decide. Immediately after the injection of the ammonia water, seal the container with a rubber stopper, shake for 10 minutes, and leave it for 5 minutes. Then, measure the ammonia concentration in the space in the bottle (measured when the amount of vaporized ammonia decreases due to the deodorizing effect of the sample). The ammonia concentration in the gas phase is lower than the above calculated value.)

Table 2 shows the results of the above-mentioned tests performed on the horsetail extract according to the above-mentioned Production Examples, and the results of the same tests performed by placing 20 ml of pure water in a wide-mouth bottle as a control.
