Abstract

PROBLEM TO BE SOLVED: To provide a composition which can improve a body odor by being orally administered.SOLUTION: The oral body odor-improving composition includes camphor and hexenol, and further includes one or more compounds selected from linalool oxide, anethole and phenethyl alcohol.

Description

  The present invention relates to a composition for improving oral body odor, and more particularly to a composition for improving body odor that can improve human body odor by ingestion orally and a method for improving body odor using the same.

  Body odor is composed of various volatile components released from the body, and is known to change in various situations such as diet, stress, aging, and various diseases. In particular, the relationship between eating habits and body odor is widely known, and a typical example is Oiso.

  This body odor includes the odor of ingredients contained in human sweat, the smell of secretions from the skin, or the odor caused by their oxides, foul odor, foot odor, halitosis, manure odor, aging odor, etc. It has been known. Since these odors feel unpleasant for humans, various measures have been taken to eliminate these odors (Patent Documents 1 to 3).

  However, as described above, the body odor is a composite odor composed of various odor components, and it is very difficult to cope with various odors, and it cannot be said that sufficient measures are taken.

  On the other hand, Kampo medicines that improve body odor have also been reported for a long time in medical minds, and as a representative example, body aroma is known. The body fragrance is made of herbal medicine with strong fragrance, and it is said that when ingested, it releases fragrance from the body and can improve body odor.

  In addition, regarding linalool, citronellol and geraniol, which are representative components of the scent of roses, these components themselves are released from the body (Non-patent Document 1) and can improve body odor. That is, it can be said that a substance released from the body by ingestion may have an effect of improving body odor.

  However, compounds or compositions that have been released from the body surface by oral ingestion and have a sufficient effect to exhibit an unpleasant body odor (hereinafter referred to as “masking”) and a harmony effect (hereinafter referred to as “harmonage”) have hitherto been used. The fact was not known. In addition, the “harmonage” in the present invention is an effect that makes it possible to harmonize the whole odor including body odor even in the presence of various body odors, and to eliminate the discomfort of body odors. Means.

  The range of the amount of camphor and hexenol consumed per day using the composition for improving body odor of the present invention produced as described above varies depending on the age of the intake person, the intensity of body odor, and the like. However, it is usually 1 mg to 10000 mg, preferably 5 mg to 5000 mg, more preferably 10 mg to 3000 mg per day. What is necessary is just to divide the oral body odor improving composition which becomes such an amount into 1 to several times.

  Similarly, the range of the amount of linalool oxide, anethole, and phenethyl alcohol when used in combination also varies depending on the age of the user, the intensity of body odor, etc., but is usually 1 mg to 10,000 mg per day, preferably It is 5 mg to 5000 mg, more preferably 10 mg to 3000 mg. What is necessary is just to divide the oral body odor improving composition which becomes such an amount into 1 to several times.

  By ingesting the above amount from the oral route, the aroma component is released from the body surface, and the body odor can be masked and / or harmonized and deodorized.

  The present invention will be described more specifically with reference to the following examples. However, the present invention is not limited thereto.

Example 1
In vitro transpiration test:
Camphor, cis-3-hexenol, linalool oxide, anethole, and phenethyl alcohol were each administered into the duodenum at a dose of 1 mL / kg to SD male rats under pentobarbital anesthesia. A glass vial with a capacity of 10 mL was attached to the site including the bottom of the foot, and the transpiration was collected for 3 hours. At this time, the temperature of the glass vial was kept at about 40 ° C.

  The collected transpiration material in the glass vial was collected with 1 mL of ethanol, filtered through a 0.45 μm filter, and then analyzed using a GC-MS system (TraceGC-PoralisQ) manufactured by Thermo Fisher Scientific. did.

  DB-5 ms (30 m × 0.25 mm × 0.25 μm) was used for the analytical column, helium gas was used for the carrier gas, and the flow rate was 1.2 mL / min. The oven temperature was held at 50 ° C. for 1 minute, then increased to 180 ° C. at a rate of 5 minutes per minute, then increased to 300 ° C. at a rate of 20 ° C. per minute and held for 5 minutes. The inlet temperature was 250 ° C., the ion source temperature was 230 ° C., and the transfer line temperature was 280 ° C.

  As a result of analyzing the mass spectrum of the peak of the obtained chromatogram, it was confirmed that the collected components were contained in the collected transpiration product.

  As a result of the above, it was revealed that after ingesting camphor, hexenol, linalool oxide, anethole, and phenethyl alcohol, the components themselves are released from the body surface.

Example 2
Deodorization test 1:
(1) Compositions 1-4 and comparative compositions 1-2 containing camphor, cis-3-hexenol, linalool oxide, anethole and phenethyl alcohol in the amounts shown in Table 1 were prepared.

(2) Compositions 1 to 4 and Comparative compositions 1 and 2 prepared in (1) above were added into a vial having a capacity of about 150 cm ³ , and 0.1 mL of the following aging odor model was further added. Next, the masking and harmony effects on the aging odor model were verified by the following sensory evaluation test. The results are shown in Table 2.

(Aging odor model)
Component Mass (%)

<Effect on aging odor>

  As a result, it became clear that the compositions 1 to 4 showed superior masking effect and harmony effect compared to the comparative compositions 1 and 2 for the aging odor model.

Example 3
Deodorization test 2:
Add compositions 1 to 4 and comparative compositions 1 to 2 shown in Table 1 of Example 2 into a vial having a capacity of about 10 mL, and further add 1 mL of air in the vial containing the following bad breath model or foot odor model. It was added using a syringe. Next, masking and harmony effects on bad breath and foot odor were verified by the following sensory evaluation test. The results are shown in Tables 3 and 4.

(Bad breath model)
To a vial of about 10 mL capacity, 100 μL of 2-mercaptoethanol was added.
(Foot odor model)
To a vial with a volume of about 10 mL was added 100 μL of iso-amino acid.

(Sensory evaluation of masking)
The masking effect was evaluated with the following five-level score.
1: Feels bad breath or foot odor very strongly 2: Feels bad breath or foot odor 3: Feels bad breath or foot odor 4: Feels weak or bad foot odor 5: Does not feel bad breath or foot odor

(Sensory evaluation of harmony)
The harmony effect was evaluated using the following five-point score.
2: Harmonized 1: Slightly harmonized 0: Neither -1: Slightly harmonized -2: Not harmonized

<Effects on bad breath model>

<Effects on foot odor model>

  As a result, it became clear that the compositions 1 to 4 showed superior masking effect and harmony effect compared to the comparative compositions 1 and 2 for the bad breath and foot odor models.

Treatment example 1
Preparation of oral solution:
The components listed in Table 5 below were dissolved in 15% of the total amount of water and stirred thoroughly. Next, the pH was adjusted to 3.0 with citric acid and sodium citrate, and a beverage stock solution having a concentration of 25% of the total amount was prepared. Finally, purified water was added to the beverage stock solution to make a total amount, and the solution was filled in a 100 ml glass bottle to obtain an internal solution. This internal liquid solution was able to improve body odor and had good dosing properties.

  The composition of the present invention can be masked and / or harmonized by ingesting it, effectively improving body odor and effectively reducing unpleasant body odor.
