Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorant composition which has an excellent deodorizing effect on a wide range of malodors and can be produced at low cost.

[0002]

2. Description of the Related Art Polyphenol (also referred to as polyhydric phenol) is a general term for compounds having two or more hydroxyl groups on the same benzene ring. This polyphenol is widely present in plants (for example, tea) and has a deodorizing effect (it is said that the inclusion of malodorous substances by the polyphenol is one of the causes). Therefore, many deodorants containing the plant extract (for example, tea extract) containing the polyphenol as an active ingredient have been provided so far. However, because polyphenols are very expensive,
If the concentration is increased to increase the deodorizing effect, there is a problem that the product becomes too expensive.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a technique for improving the deodorizing activity of polyphenol without increasing the amount of the polyphenol compound.

[0004]

Means for Solving the Problems The present inventors have made intensive efforts to solve the above-mentioned problems, and as a result, have found the existence of a polyphenol deodorizing action enhancer which improves the deodorizing activity of polyphenol. The invention has been completed.

That is, the present invention relates to a deodorant composition containing polyphenol as an active ingredient, characterized in that it contains a polyphenol deodorizing action enhancer (1).

[0006] The present invention also relates to (2), wherein the enhancer is a monohydric lower alcohol.

Further, the present invention relates to the composition (2), wherein the monohydric lower alcohol is ethanol, isopropanol or a mixture thereof (3).

[0008] The present invention also relates to a polyphenol represented by the formula:

[0009]

Wherein R represents a hydrogen atom or a hydroxyl group, and R ′ represents a hydrogen atom or a galloyl group, wherein the composition is a condensed tannin containing a repeating unit represented by the following formulas (1) to ( (4) regarding 3).

Further, the present invention relates to the composition (4), wherein the polyphenol is persimmon tannin (5).

BEST MODE FOR CARRYING OUT THE INVENTION The polyphenol according to the present invention comprises
Not particularly limited, for example, having a resorcinol, pyrocatechol, pyrogallol, phloroglucinol, chlorogenic acid, caffeic acid, 2,4-dihydroxybenzoic acid, ellagic acid, rosmarinic acid, tannic acid, rutin, quercetin, anthraquinone skeleton Compounds, compounds having an anthocyanin skeleton, compounds having a procyanidin skeleton, and the like can be given. Preferably, the formula:

(Wherein, R represents a hydrogen atom or a hydroxyl group, and R 'represents a hydrogen atom or a galloyl group). Particularly preferred is persimmon tannin.

The polyphenol according to the present invention can be extracted from a synthetic or natural product by a conventional method. Examples of commercially available products extracted from natural products include persimmon fruit extracts such as Pansil (manufactured by Release Science Co., Ltd.), and green tea extracts include sunfood (manufactured by Sankyo Co., Ltd.). ,
Theafuran (manufactured by Itoen Co., Ltd.), Sanphenon (manufactured by Taiyo Kagaku Co., Ltd.), polyphenone (manufactured by Mitsui Norin Co., Ltd.), and the like, and oolong tea extract include sun oolong (manufactured by Suntory Ltd.), etc. Examples of the apple fruit extract include apple phenone (manufactured by Nikka Whiskey Co., Ltd.).

Normally, when these polyphenols are used alone, it is necessary to mix them at a relatively high concentration in order to achieve the desired deodorizing effect, so that the cost is increased and the extract itself is used. Is sometimes unfavorable in practical use. However, in the present invention, a desired deodorizing effect can be exhibited even when the concentration of the polyphenol is low, by combining the polyphenol with its deodorizing action enhancer (for example, a lower alcohol).

The content of polyphenol in the composition according to the present invention is 0.000.00% based on the total weight of the composition.
It is preferably from 1 to 3.0% by weight, and from 0.01 to 1% by weight.
More preferably, it is% by weight. The above content is 0.0
If it is less than 01%, a desired deodorizing effect may not be obtained, and if it exceeds 3.0%, it is costly and cannot be produced inexpensively, or there is a problem of odor and coloring of polyphenol itself. May be less preferred.

The monohydric lower alcohol according to the present invention is:
Refers to a monovalent chain alcohol having 1 to 5 carbon atoms, for example,
Examples include methanol, ethanol, propanol, isopropanol, and butanol. Ethanol and isopropanol are preferred. Note that a plurality of monohydric lower alcohols may be used in combination. In this case, a mixture of ethanol and isopropanol is preferable.

Although the lower alcohol enhances the deodorizing action of the polyphenol compound, it also has an action of diffusing malodorous substances due to its volatility, so that it is not preferable to mix it at a high concentration. In addition, when a high concentration is blended, the polyphenol may be insolubilized and precipitate in the composition in some cases. Therefore, the preferred content in the composition is 1 to the total weight of the composition.
-30% by weight, more preferably 3-20% by weight.

The deodorant composition according to the present invention comprises, in addition to the above components, an organic acid (for example, citric acid), a pH adjuster, a fragrance,
A surfactant, a bactericide, a preservative, and the like may be appropriately contained.

The deodorant composition according to the present invention can be filled in an appropriate container and used as a spray, or impregnated in paper or nonwoven fabric or the like and used for deodorizing fingers or objects.
