PROBLEM TO BE SOLVED: To provide a deodorant having a deodorizing effect on an unsaturated aldehyde. SOLUTION: This deodorant is characterized by containing condensation type persimmon tannin.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention provides a body odor deodorant having an excellent deodorizing effect on unsaturated aldehydes by containing a condensed oyster tannin.

[0002]

2. Description of the Related Art As disclosed in Japanese Patent Application Laid-Open No. 11-286423, the so-called "aging odor" observed after middle-aged and older people has a completely new property in which unsaturated aldehydes such as octenal and nonenal are closely related. Body odor.
And conventionally, in order to remove those "aging odors",
The purpose was to mask the generated unsaturated aldehyde with a fragrance, or to suppress the generation by inhibiting oxidation by an antioxidant and by inhibiting the growth of bacteria indigenous to the skin by an antibacterial agent.

[0003]

However, so-called conventional deodorant substances such as tea extract, perilla extract, oak extract, cucumber extract, sansho extract, parsley extract, hamamelis extract, tannic acid, etc. The deodorizing effect of the unsaturated aldehyde containing the compound was not yet satisfactory.

[0004]

Means for Solving the Problems In view of the above, the present inventors have conducted intensive studies and as a result, found that condensed oyster tannin has a remarkable deodorizing effect on unsaturated aldehydes, and completed the present invention. It led to.

Hereinafter, the configuration of the present invention will be described in detail. The blending amount is not particularly limited, but is preferably in the range of 0.0001 to 5% by weight as a dry product in the total amount of the external preparation for skin. Preferably, it is 0.001 to 3% by weight. More preferably, it is 0.01 to 1% by weight. 0.0001
%, The deodorizing effect cannot be exhibited. On the other hand, when the content is 5% by weight or more, the effect is not enhanced and it is uneconomical.

The condensed oyster tannin according to the present invention is obtained from the juice of the fruit of Diospyros kaki Thunberg (Ebenaceae). The juice is obtained by sealing and storing the juice using an enzyme, removing sugars, and dehydrating under reduced pressure.

[0007] In addition to the above essential components, the external preparation for skin of the present invention includes various components used in ordinary cosmetics, quasi-drugs, pharmaceuticals, etc., such as oil components, emulsifiers, humectants, thickeners,
Pharmaceutical ingredients, preservatives, pigments, powders, pH adjusters, ultraviolet absorbers, antioxidants, fragrances, and the like can be appropriately compounded.

[0008] Specifically, oily components include, for example, liquid paraffin, vaseline, microcrystalline wax, squalane, jojoba oil, beeswax, carnauba wax, lanolin, olive oil, coconut oil, higher alcohols,
Examples include fatty acids, esters of higher alcohols and fatty acids, and silicone oils. Examples of the emulsifier include nonionic surfactants such as polyoxyethylene alkyl ether, polyoxyethylene fatty acid ester, polyoxyethylene sorbitan fatty acid ester, sorbitan fatty acid ester, glycerin fatty acid ester, polyglycerin fatty acid ester, and polyoxyethylene hydrogenated castor oil. Is mentioned. Examples of the humectant include glycerin, sorbitol, xylitol, maltitol, propylene glycol, polyethylene glycol, 1,3-butylene glycol, polyoxyethylene methyl glucoside, and the like. Examples of the thickener include carboxyvinyl polymer, xanthan gum, methylcellulose, polyvinylpyrrolidone, gelatin and the like. Examples of the medicinal component include vitamin C and its derivatives, vitamin E derivatives, placenta extract, kojic acid, arbutin, allantoin, glycyrrhizic acid derivatives, and various plant extracts.

[0009] The dosage form of the body odorant of the present invention can be arbitrarily selected according to the purpose such as basic cosmetics such as mist, gel, lotion, aerosol, and emulsion.

[0010]

The present invention has an excellent deodorizing effect on unsaturated aldehydes by containing condensed oyster tannin.

[0011]

[Experimental example] The deodorizing effect was evaluated by gas chromatography, and the deodorizing rate of the unsaturated aldehyde was compared with that of a blank. Nonenal was used as the unsaturated aldehyde. Conditions Column: PEG20M (80/100) 3mmφ × 2.0m, Temperatu
re: Oven 150 ℃, Injection: 250 ℃, Detector: 250
℃, Range: 10 Detector: FID measurement method
After the temperature is kept constant at 5 ° C., 5 ml of gas is collected. On the other hand, a sample of 1 g is collected in a Bayer bottle, the temperature is kept constant at 40 ° C., and 5 ml of nonenal gas previously collected is added and left for 10 minutes. 1 ml of the gas was collected, and the peak area of nonenal was compared with that of the blank by gas chromatography to determine the deodorizing effect. In addition, each comparative sample is a raw material which is actually commercially available and used regularly. (Manufacturer: Ichimaru Falcos Co., Ltd.)

[0012]

[Table 1]

From the results in Table 1, it can be seen that the preparation of condensed oyster tannin is excellent in the deodorizing effect of unsaturated aldehyde.

[0014]

[Table 2]

From the results shown in Table 2, it can be judged that the amount of the condensed oyster tannin is more preferably 0.01 to 5% by weight.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below, but the present invention is not limited to these embodiments.

[0017]

EXAMPLES Skin external preparations formulated and designed as shown in Tables 3 to 7 were prepared and evaluated for the deodorizing effect of aging odor by the following test methods.

A questionnaire survey was conducted in advance to select 10 deodorants for persons suffering from age-related odors. The subjects were given an appropriate amount of the aging odor continuously every day for 2 weeks at the part where the above-mentioned symptoms were worrisome, and evaluated on a 5-point scale according to the following criteria. Tables 3 to 7 show the average scores. 5: Significant effect. 4: Very effective. 3: There is some effect. 2: Almost no effect. 1: No effect.
