[Industrial application fields]
This invention provides the body odor deodorant which has the outstanding deodorizing effect with respect to unsaturated aldehyde by containing condensed type cachytannin.
[0002]
[Prior art]
As disclosed in Japanese Patent Application Laid-Open No. 11-286423, so-called “aged odor” recognized after middle-aged and older is a completely new body odor that is deeply related to unsaturated aldehydes such as octenal and nonenal. In order to remove these “aged odors”, conventionally, the generated unsaturated aldehyde is masked with a fragrance, or it is generated by inhibiting oxidation with an antioxidant, or inhibiting growth of resident skin bacteria with an antibacterial agent. It was to suppress.
[0003]
[Problems to be solved by the invention]
However, deodorization of unsaturated aldehydes containing so-called conventional deodorizing substances such as tea extract, perilla extract, ougon extract, cucumber extract, salamander extract, parsley extract, hamamelis extract, tannic acid, etc. The effect was not yet satisfactory.
[0004]
[Means for Solving the Problems]
As a result of intensive studies in view of the above matters, the present inventors have found that condensed cachytannin has a remarkable deodorizing effect on unsaturated aldehydes, and has completed the present invention.
[0005]
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 in the total amount of the external preparation for skin as a dry product. Preferably, it is 0.001 to 3 weight%. More preferably, it is 0.01 to 1 weight%. If it is less than 0.0001%, the deodorizing effect cannot be exhibited. On the other hand, if it is 5% by weight or more, the effect is not enhanced and it is uneconomic.
[0006]
The condensed oyster tannin according to the present invention is obtained from the squeezed fruit of Diospyros kaki Thunberg (Ebenaceae), and the production method thereof comprises squeezing the fruit to obtain a squeezed liquid and drying it under reduced pressure, or It is obtained by removing sugars after dehydrating under reduced pressure after hermetically storing with.
[0007]
In addition to the above essential components, the external preparation for skin of the present invention includes various components used in normal cosmetics, quasi drugs, pharmaceuticals, etc., for example, oily components, emulsifiers, humectants, thickeners, medicinal components, preservatives Pigments, powders, pH adjusters, ultraviolet absorbers, antioxidants, fragrances and the like can be appropriately blended.
[0008]
Specific examples of the oil component include liquid paraffin, petrolatum, microcrystalline wax, squalane, jojoba oil, beeswax, carnauba wax, lanolin, olive oil, coconut oil, higher alcohol, fatty acid, ester of higher alcohol and fatty acid, silicone oil, and the like. Is mentioned. 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, methyl cellulose, polyvinyl pyrrolidone, gelatin and the like. Examples of medicinal ingredients include vitamin C and its derivatives, vitamin E derivatives, placenta extract, kojic acid, arbutin, allantoin, glycyrrhizic acid derivatives, various plant extracts, and the like.
[0009]
The dosage form of the body odorant of the present invention can be arbitrarily selected according to the purpose of basic cosmetics such as mist, gel, lotion, aerosol, and emulsion.
[0010]
【The invention's effect】
The present invention has an excellent deodorizing effect on unsaturated aldehydes by containing condensed cachytannin.
[0011]
[Experimental example]
The deodorization effect was evaluated by gas chromatography, and the deodorization rate of unsaturated aldehyde was compared with that of the blank. As the unsaturated aldehyde, nonenal was used.
Conditions Column: PEG20M (80/100) 3mmφ × 2.0m, Temperature: Oven 150 ° C, Injection: 250 ° C, Detector: 250 ° C, Range: 10 Detector: FID
Method of measurement Noneal is sampled in a 1 g Bayer bottle, brought to a constant temperature of 40 ° C., and 5 ml of gas is sampled. On the other hand, a sample is collected in a 1 g Bayer bottle, brought to a constant temperature of 40 ° C., 5 ml of the previously collected nonenal gas is added and left for 10 minutes. 1 ml of the gas was sampled, and the peak area of nonenal was compared with a blank by gas chromatography to determine the deodorizing effect.
Each comparative sample is actually a commercially available and commonly used raw material. (Manufacturer: Ichimaru Falcos)

[Table 1]

[0013]
From the results shown in Table 1, it can be seen that the preparation of condensed cachytannin is excellent in the deodorizing effect of unsaturated aldehyde.
[0014]
[Table 2]

[0015]
From the results shown in Table 2, it can be determined that the blending amount of the condensed oyster tannin is more preferably 0.01 to 5 wt.
