Description

TECHNICAL FIELD The present invention relates to a deodorant composition containing a crude drug yoquinin as a raw material and having an unpleasant body odor emitted by the human body, a method for producing the same, an external preparation and a deodorant product containing the body odor deodorant composition.
Specifically, it is a body odor deodorant composition that is particularly effective against unpleasant odors such as 2-nonenal and isovaleric acid among body odors, has no odor derived from raw materials, and is safe for the human body.

The unpleasant body odor emitted by the human body includes foot odor, axillary odor, and sweat odor. Secretions containing a large amount of fatty acids and proteins secreted mainly from the apocrine gland are decomposed by epidermis indigenous bacteria, and capric acid, caproic acid, isovaleric acid, butyric acid, propionic acid, enanthic acid, lactic acid, etc., generated from them are uncomfortable. It is said to be the cause of odor.
Recently, with the aging of society, attention has been paid to the age-related odor, which is completely different from foot odor, axillary odor, and sweat odor, and is one of the unpleasant odors that are especially disliked among body odors. ..
The causative substance of aging odor peculiar to the elderly is an unsaturated aldehyde such as octenal or nonenal which is generated by decomposition of higher unsaturated fatty acid such as palmitoleic acid in sebum by indigenous skin bacteria. In particular, nonenal is a major odor-causing substance that is detected in men and women after the age of 40 and whose frequency and amount increase with age.

As measures against the above body odor, sprays and wet tissues containing silica and magnesium oxide, which are cosmetic minerals, are in circulation to deodorize sweat, armpits, and foot odors. There was a problem that white clothes float on dark clothes and stain the clothes.

In addition, plant-derived deodorants have come to be used in consideration of safety and preference for natural products. Specifically, a green tea extract, a dokudami extract, a ripe extract, a lavender extract, a persimmon leaf extract, a mate tea extract, etc. are known (nonpatent literature 1). However, these plant extracts are often difficult to use as a body odor deodorant because the extract itself has a strong odor, and from the viewpoint of safety to the skin, it is directly applied to the skin. It was difficult to use it as a deodorant for body odor.

As a plant-derived deodorant that has been confirmed to be safe when applied directly to the skin, a deodorant composed of an extract of a mixture of Toki, peony, senkyu, and dio is proposed (Patent Document 1). Further, a deodorant composition composed of an extract of Toki, Peony, Senkyu, Zyou, and ginger has also been proposed (Patent Document 2).
However, all of them have the odor of the extract itself, and have not completely solved various problems to be overcome as a useful body odor eliminating agent desired by consumers.

Miyamoto, Kawauchi, "Deodorant action of plant extracts," Fragrance Journal, Fragrance Journal, No. 65 (Vol. 12, No. 2), (1984), p. 82-85 Shanghai Science and Technology Publishing Co., Ltd., "Chinese Medicine Dictionary Vol. 4, Shogakukan Co., Ltd., published May 1, 1998, pp. 2626-2628.

The object of the present invention is to solve the problems in existing deodorant products, and is highly deodorant for human body odor, particularly for body odor components such as isovaleric acid and unsaturated aldehydes such as 2-nonenal. To provide a body deodorant composition which is effective and has no unpleasant odor derived from raw materials, little coloring of clothes such as white float, and low irritation to the skin and safe. Is.

In order to solve the above problems, the present inventor has focused on various plant-derived components and examined the presence or absence of the deodorizing action and the degree thereof. As a result, the deodorizing effect of body odor was found in a solvent extract of adlay seeds (the seeds of which are removed to obtain the crude drug Yokuinin).
However, the ingredient causing the unpleasant odor peculiar to Yokuinin remains in Yokuinin extract, and there is a problem in using Yokuinin extract as it is as a body odor deodorant.

Therefore, the present inventor has made extensive studies on a deodorizing method for the odor of Yokuinin, and there is a slight difference in polarity between the odor component contained in Yokuinin and the deodorant component for body odor contained in Yokuinin. , It was found that they can be separated by utilizing the difference in the elution property with respect to the extract and the eluent.
Therefore, by combining the extraction treatment of Yokuinin and the adsorbent treatment and further specifying the properties of the extract and eluent, it was found that an extract from which the odor component of Yokuinin was removed can be obtained as a body odor eliminating composition. It was

[A] Body odor deodorant (1) Raw material The raw material of the active ingredient of the body odor deodorant of the present invention is Coix, which is an annual herb of the Poaceae family.
lacryma-jobi L. ver. ma-yuen Stapf) seeds without seed coat, that is, Yokuinin which is a crude drug. The seeds are not necessarily limited to Coix seeds, and seeds of the original plant Juzudama, varieties, congeners, and other closely related species can also be used.

The major ingredients of yoquinin are starch (50-80%), protein (16-20%), palmitic acid, stearic acid, glycerides of cis-8-stearic acid and fatty oils and fatty acids such as carp quinoceride, and acid such as coixane A to C. It is a polysaccharide.
The beneficial effects of Yokuinin include nourishment, tonicity, wart removal, and anti-roughness. Coixanes have hypoglycemic action, and carp quinoxelide has antitumor effect. In Chinese medicine, it has been used for diuresis, anti-inflammatory, analgesia, and drainage.
Yokuinin is said to have a skin-refining effect, and has been used as a herbal medicine that has been favored by women since ancient times in Japan (Non-patent Document 2; “Honzo Tsuname Kao Tei Nairin Medium Woman Facial Treatment”, Written by Zhang Xuan, published by Gold Bullion Cultural Business Co., Ltd., November 2010).
Yokuinin has been used as a crude drug for a long time, but it has a peculiar unpleasant odor expressed as grain odor, burdock odor, oxidized odor of oil and fat, mold odor, cardboard odor, fishy odor, and the like.

(2) Solvent Extraction Treatment Yokuinin is oval with a length of about 6 mm and a width of about 5 mm, so it is preferably processed into a powder and then extracted with a solvent. It should be noted that it is convenient to use a commercially available Yokuinin powder which is a powder of Yokuinin because the powdering can be omitted.
The solvent is one or two selected from the group consisting of water, ethanol, 1,3-butylene glycol, propylene glycol, dipropylene glycol, glycerin, diglycerin, 1,2-pentanediol and 1,3-propanediol. The above solvents are preferred.
Here, the body odor eliminating component contained in Yokuinin exhibits non-adsorbability with the synthetic adsorbent under the condition of 50 to 90% ethanol concentration, particularly 60 to 80% ethanol concentration. Therefore, when an ethanol aqueous solution having an ethanol concentration of 50 to 90%, particularly 60 to 80% is used as the extraction solvent, it is advantageous in that the desorption treatment after the adsorption treatment of the extraction liquid with the synthetic adsorbent is unnecessary. ..
The amount of the solvent used at the time of extraction is preferably 10 to 100 times, especially 15 to 50 times the mass of the substance to be extracted (yokuinin) in terms of mass ratio.

The extraction temperature is not particularly limited, but is usually 0 to 150°C, preferably 20 to 100°C, more preferably 25 to 80°C. If the extraction temperature is lower than 0°C, the extraction may take a long time, and if the extraction temperature exceeds 150°C, it may cause turbidity.
Suitably, after heating and refluxing extraction at 80 to 100° C. for about 0.5 to 3 hours, solid-liquid separation is performed using a filter paper or the like to obtain yokuinin extract.
It should be noted that using a commercially available Yokuinin extract sold as Yokuinin extract is convenient because the solvent extraction step can be omitted and the next adsorbent treatment can be carried out immediately.

(3) Adsorbent treatment Next, the Yokuinin extract obtained in the above extraction treatment is brought into contact with the synthetic adsorbent to perform adsorption treatment.
By this adsorption treatment, the odor component of Yokuinin in the Yokuinin extract is adsorbed on the adsorbent.
On the other hand, the body odor-deodorizing component contained in Yokuinin has adsorbability which depends on the properties of the solvent when it contacts the adsorbent. That is, the body odor deodorizing component exhibits non-adsorbability with the synthetic adsorbent under conditions of 50 to 90% ethanol concentration, but under other solvent conditions (that is, an aqueous solution of ethanol of less than 50% or more than 90%, or ethanol). In a solvent other than the aqueous solution (for example, water, butylene glycol, etc.), it is adsorbed by the synthetic adsorbent together with the odor component of yochinin.

The synthetic adsorbent used in the present invention is not particularly limited as long as it is a porous aromatic synthetic resin adsorbent having substantially no ion exchange ability, but it is preferably The base is a styrene type, for example, "Amberlite (registered trademark) XAD-16" (manufactured by Organo Corporation), styrene-divinylbenzene type, for example, "Diaion (registered trademark) HP-20" (manufactured by Mitsubishi Chemical Corporation), "Sepa beads (registered trademark) SP-700" (manufactured by Mitsubishi Chemical Co., Ltd.), acrylic-based, such as "Diaion WK-10" (manufactured by Mitsubishi Chemical Co., Ltd.), methacrylic-based, such as "Diaion HP-2MG" (Mitsubishi Chemical Co., Ltd.), acrylic acid ester type such as “Amberlite XAD-7” (manufactured by Organo Corporation), amide type such as “Amberlite XAD-11” (manufactured by Organo Corporation), dextran type such as “Sepha. Dex (registered trademark) G-25" (manufactured by Amersham Pharmacia Biotech), polyvinyl-based such as "Diaion FP-II" (manufactured by Mitsubishi Chemical Co., Ltd.) and the like can be used. The pore diameter is preferably 50 to 300Å.

An example of a particularly preferable adsorbent is “Sepa beads (registered trademark) SP-70” manufactured by Mitsubishi Chemical Corporation. SepaBeads SP-70 is a copolymer of styrene and divinylbenzene, and has a particle size distribution of 250 μm or more (90% or more), an effective diameter of 0.25 mm or more, a uniformity coefficient of 1.6 or less, and a pore volume of 1. It has a specific surface area of 5 ml/g, a specific surface area of 870 m ² /g, and a most frequent radius of 70Å.

As a method of adsorbing the Yokuinin extract to the synthetic adsorbent, a synthetic adsorbent is added to the Yokuinin extract, stirred and adsorbed, and then a batch method of collecting the synthetic adsorbent by a filtration operation or a column packed with the synthetic adsorbent A column method in which an adsorption treatment is carried out by continuous treatment is adopted, but a continuous treatment method by a column is preferable from the viewpoint of productivity.

The amount of the synthetic adsorbent used is preferably 5 to 50% by volume based on the yochinin extract, from the viewpoint of the adsorption efficiency of the yoquinin odor component in the extract.
The conditions for passing the yochinin extract through the column packed with the synthetic adsorbent are: SV (space velocity)=0.5 to 5 [h ^-1 ], preferably 1 to 3 [h ^-1 ] It is preferable to pass liquid at a rate of multiple times (BV)=1 to 10 [v/v] with respect to the synthetic adsorbent, because the odor component of yoquinin in the extract can be sufficiently adsorbed.

(4) Desorption treatment By the desorption treatment, the body odor deodorant component of Yokuinin is desorbed and separated while leaving the odor component of Yokuinin in the adsorbent.
As described above, the body odor eliminating component exhibits non-adsorbability with the synthetic adsorbent under the condition of 50 to 90% ethanol concentration. Therefore, for example, when the extraction liquid when contacted with the adsorbent is an aqueous ethanol solution having a concentration of 50 to 90%, the odor component of Yokuinin is adsorbed, but the deodorant component of body odor is not adsorbed and the column packed with the synthetic adsorbent is not adsorbed. Since it passes and is discharged, the desorption process is unnecessary.

On the other hand, when the extract liquid brought into contact with the adsorbent has properties other than an aqueous solution of ethanol of 50 to 90% concentration, both the scent of Yokuinin odor and the deodorant of body odor are adsorbed on the synthetic adsorbent. Is required.
An ethanol aqueous solution having a concentration of 50 to 90%, preferably an aqueous ethanol solution having a concentration of 60 to 80% is used as an eluent for desorption. When the ethanol concentration is less than 50% or more than 90%, a sufficient yochinin odor removing effect cannot be obtained.

The conditions for passing the eluent through the column packed with the synthetic adsorbent are: SV (space velocity) = 0.5 to 5 [h ^-1 ] and the multiple times (BV) for the synthetic adsorbent. )=1 to 10 [v/v] is preferable since the active ingredient for deodorizing body odor can be sufficiently eluted in the desorbed liquid.
Through the above-mentioned treatment, it is possible to obtain the Yokuinin extract liquid in which the odor component contained in Yokuinin is removed and which is excellent in the deodorizing effect of body odor.

Here, the body odor and deodorant composition obtained by the above-described production method contains a very large amount of components, as in the case of extracts from other plants. In other words, the desired body odor eliminating effect is exhibited in a composition in which various components such as carbohydrates, proteins, amino acids, fats, pigments, vitamins, and aroma components are contained in a complicated state or in a mixing ratio.
Therefore, in order to directly specify the body odor deodorant of the present invention by the structure and characteristics, it is essential to identify and quantify the constituents, but to identify and quantify all the constituents is common technical point of view. Impossible or almost impractical.
