特許法第30条第2項適用 株式会社APAコーポレーションは、京急第2ビルで令和1年9月29日に開催されたAPAコーポレーション販社会議において、本願発明に係る皮膚の老化防止用組成物を公開した。Application of Article 30, Paragraph 2 of the Patent Act APA Corporation unveiled the composition for preventing skin aging of the present invention at the APA Corporation Sales Conference held at Keikyu 2nd Building on September 29, 2019.
本発明は、皮膚の老化防止用組成物に関する。 The present invention relates to a composition for preventing skin aging.
現代における美容意識の高まりに伴い、皮膚のシワや、皮膚のハリ等を改善する老化防止化粧料が、種々提案されている。
このような老化防止化粧料として、例えば特許文献1に、ハイビスカス抽出物が開示されている。ハイビスカス抽出物は、線維芽細胞の増殖を活性化させ、皮膚のシワや、皮膚のハリ等を改善する可能性があると考えられている。
2. Description of the Related Art With the increasing awareness of beauty in modern times, various anti-aging cosmetics that improve wrinkles, skin firmness, and the like have been proposed.
As such an anti-aging cosmetic, for example, hibiscus extract is disclosed in Patent Document 1. It is believed that hibiscus extract may activate the proliferation of fibroblasts and improve wrinkles, firmness, and the like of the skin.
単に線維芽細胞の増殖を活性化させるのみでは、皮膚のシワや、皮膚のハリ等を十分に改善することができない虞がある。 There is a risk that simply activating the proliferation of fibroblasts may not be enough to sufficiently improve skin wrinkles and skin firmness.
本発明は、上記問題点に鑑みてなされたものであり、従来よりも、皮膚のシワや、皮膚のハリ等を改善することが可能な、皮膚の老化防止用組成物を提供することを目的とする。 The present invention has been made in consideration of the above problems, and aims to provide a composition for preventing skin aging that can improve skin wrinkles, skin firmness, etc. more than ever before.
上記目的を達成するため、本発明の皮膚の老化防止用組成物は、
珪素と、pH調整剤と、を含有しており、
前記珪素の含有量が、0.05質量%以上100質量%未満であり、
前記珪素は、水晶から抽出された水溶性の珪素であり、
皮膚のシワ及び皮膚のハリを改善する為に使用され、
皮膚に塗布して使用される。
In order to achieve the above object, the composition for preventing skin aging of the present invention comprises:
Contains silicon and a pH adjuster,
The silicon content is 0.05% by mass or more and less than 100% by mass,
The silicon is water-soluble silicon extracted from quartz,
It is used to improve skin wrinkles and skin firmness.
It is used by applying it to the skin.
例えば、前記珪素の含有量が、0.05質量%以上5.0質量%未満であってもよい。
For example, the silicon content may be 0.05 mass % or more and less than 5.0 mass %.
本発明によれば、従来よりも、皮膚のシワや、皮膚のハリ等を改善することが可能な、皮膚の老化防止用組成物を提供することが可能になる。 The present invention makes it possible to provide a composition for preventing skin aging that can improve skin wrinkles, skin firmness, and other skin problems more effectively than ever before.
以下、本発明の実施の形態に係る皮膚の老化防止用組成物について説明する。 The following describes the composition for preventing skin aging according to an embodiment of the present invention.
本発明の皮膚の老化防止用組成物は、珪素を含有している。 The composition for preventing skin aging of the present invention contains silicon.
珪素は、非晶質珪素であり、例えば、食物由来の珪素や、鉱物由来の珪素が挙げられる。
食物由来の珪素としては、穀類、野菜類、海藻類などに含まれる珪素が挙げられる。
穀類としては、例えば、麦、玄米、白米、トウモロコシである。
野菜類としては、例えば、ゴボウ、大根、人参である。
海藻類としては、例えば、昆布、ワカメである。
穀類、野菜類、海藻類などの食物は、粉砕された状態で、本発明の皮膚の老化防止用組成物に含有されていてもよい。
The silicon is amorphous silicon, and examples of the silicon include silicon derived from food and silicon derived from minerals.
Examples of dietary silicon include silicon contained in grains, vegetables, seaweed, etc.
Examples of grains include wheat, brown rice, white rice, and corn.
Examples of vegetables include burdock, radish, and carrot.
Examples of seaweed include kelp and wakame.
Foods such as grains, vegetables, and seaweed may be contained in a pulverized state in the composition for preventing skin aging of the present invention.
鉱物由来の珪素としては、水晶から抽出した珪素が挙げられる。 Examples of silicon derived from minerals include silicon extracted from quartz.
また、珪素は、市販の珪素であってもよく、例えば、株式会社APAコーポレーションから販売されている水溶性珪素「umo(登録商標)」に含まれている珪素が挙げられる。 The silicon may be commercially available silicon, for example, silicon contained in the water-soluble silicon "umo (registered trademark)" sold by APA Corporation.
また、珪素は、単体の珪素であってもよいし、例えば二酸化珪素のように化合物中の珪素であってもよい。 The silicon may be elemental silicon or may be silicon in a compound such as silicon dioxide.
そして、本発明の皮膚の老化防止用組成物の総重量に基づく珪素の含有量は、0.005質量%以上100質量%未満である。
そして、本発明の皮膚の老化防止用組成物は、ヒトの皮膚に塗布又はヒトに飲用されると、皮膚や腸管から吸収されて、皮膚のシワやハリ等を改善すると考えられる。
The content of silicon based on the total weight of the composition for preventing skin aging of the present invention is 0.005% by mass or more and less than 100% by mass.
Furthermore, it is believed that when the composition for preventing skin aging of the present invention is applied to human skin or ingested by humans, it is absorbed through the skin and intestinal tract, improving wrinkles, firmness, and the like of the skin.
具体的には、本発明の皮膚の老化防止用組成物は、皮膚や腸管から吸収されると、以下の実施例で説明する通り、エラスターゼ活性率の低下作用、ヒアルロン酸の産出率の増加作用、及びコラーゲン分解の抑制作用などを生じさせると考えられる。
ここで、これらの作用は皮膚のシワやハリ等を改善する作用であるが、従来のハイビスカス抽出物が単に繊維芽細胞の増殖を活性化させる作用は、皮膚のシワやハリ等を改善する可能性を単に示唆するものであると考えられる。
その為、本発明の皮膚の老化防止用組成物は、従来のハイビスカス抽出物よりも、皮膚のシワや、皮膚のハリ等を改善することが可能であると考えられる。
なお、本発明の皮膚の老化防止用組成物は、ヒトの皮膚のシワやハリ等を改善するとともに、以下の実施例で説明する通り、大腸菌やレジオネラ菌を静菌させる。
Specifically, when absorbed through the skin or intestinal tract, the skin anti-aging composition of the present invention is believed to have the effect of reducing elastase activity, increasing hyaluronic acid production, and inhibiting collagen degradation, as described in the examples below.
Here, these actions are actions to improve wrinkles, firmness, etc. of the skin, but the action of conventional hibiscus extracts to simply activate the proliferation of fibroblasts is thought to merely suggest the possibility of improving wrinkles, firmness, etc. of the skin.
Therefore, it is believed that the composition for preventing skin aging of the present invention is more capable of improving skin wrinkles and skin firmness than conventional hibiscus extracts.
The composition for preventing skin aging of the present invention improves wrinkles and firmness of human skin, and also has bacteriostatic properties against Escherichia coli and Legionella pneumophila, as will be described in the following examples.
また、本発明の皮膚の老化防止用組成物の総質量に基づく珪素の含有量は、0.05質量%以上100質量%未満であることが好ましい。
これにより、本発明の皮膚の老化防止用組成物をヒトの皮膚に塗布又はヒトが飲用した際に、皮膚のシワやハリを一層改善することが可能になると考えられる。
なお、本発明の皮膚の老化防止用組成物の総質量に基づく珪素の含有量について、好ましいのは0.05質量%以上100質量%未満であるから、例えば0.1質量%、0.5質量%、1.0質量%、5.0質量%、10質量%、15質量%、20質量%、25質量%、30質量%、35質量%、40質量%、45質量%、50質量%、55質量%、60質量%、65質量%、70質量%、75質量%、80質量%、85質量%、90質量%、及び95質量%が含まれる。
The content of silicon based on the total mass of the composition for preventing skin aging of the present invention is preferably 0.05 mass % or more and less than 100 mass %.
This is believed to make it possible to further improve wrinkles and firmness of the skin when the composition for preventing skin aging of the present invention is applied to human skin or ingested by a human.
The content of silicon based on the total mass of the composition for preventing skin aging of the present invention is preferably 0.05 mass% or more and less than 100 mass%, and includes, for example, 0.1 mass%, 0.5 mass%, 1.0 mass%, 5.0 mass%, 10 mass%, 15 mass%, 20 mass%, 25 mass%, 30 mass%, 35 mass%, 40 mass%, 45 mass%, 50 mass%, 55 mass%, 60 mass%, 65 mass%, 70 mass%, 75 mass%, 80 mass%, 85 mass%, 90 mass%, and 95 mass%.
なお、本発明は、上記実施の形態に限定されず、種々の変形及び応用が可能である。 The present invention is not limited to the above embodiment, and various modifications and applications are possible.

次に、50μLの当該被験物質が入った96ウェルプレートに、50μLの1.25μg/mLエラスターゼ酵素(CAS No.39445-21-1,Sigma-Aldrich,USA)溶液及び100μLのN-Succinyl-Ala-Ala-Ala-p-Nitroanilide(CAS No.52299-14-6,Sigma-Aldrich,USA)溶液を添加し、270rpmで30秒間振とうして、その後37℃で15分間培養した。
その後、この96ウェルプレートを270rpmで10秒間振とうし、ウェル内の色素を均一に分散させて、マイクロプレートリーダーにより415nmの吸光度(OD415)を測定した。
なお、この吸光度(OD415)を用いた、珪素のエラスターゼ阻害活性の算出方法は、後述する。
[Elastase inhibitory activity of silicon]
Example 1
First, ultrapure water (CAS No. 7732-18-5, Wako, Japan) was added to and mixed with the water-soluble silicon "umo" to prepare a test substance having a concentration of water-soluble silicon "umo" of 3 mass % just before use.
Next, 50 μL of a 1.25 μg/mL elastase enzyme (CAS No. 39445-21-1, Sigma-Aldrich, USA) solution and 100 μL of an N-Succinyl-Ala-Ala-Ala-p-Nitroanilide (CAS No. 52299-14-6, Sigma-Aldrich, USA) solution were added to the 96-well plate containing 50 μL of the test substance, and the plate was shaken at 270 rpm for 30 seconds, and then incubated at 37° C. for 15 minutes.
Thereafter, the 96-well plate was shaken at 270 rpm for 10 seconds to uniformly disperse the dye in the wells, and the optical density at 415 nm (OD 415 ) was measured using a microplate reader.
The method for calculating the elastase inhibitory activity of silicon using this absorbance (OD 415 ) will be described later.

(Comparative Example 1)
Except for using ultrapure water as is, without using the water-soluble silicon "umo", the absorbance (OD 415 ) was measured in the same manner as in Example 1. Note that this comparative example is a control experiment, and ultrapure water was used as the control.
そして、実施例1~3及び比較例1で測定された吸光度(OD415)を用いて、実施例1~3の各々の珪素のエラスターゼ活性率を、次式で算出した。
エラスターゼ活性率(%)=(S-SB)×100/(C-CB)
ここで、Sは実施例1~3で測定された被験物質の吸光度、SBは実施例1~3における被験物質のブランクの吸光度、Cは比較例1で測定された対照の吸光度、CBは比較例1における対照のブランクの吸光度である。なお、ブランクでは、エラスターゼ酵素の代わりに0.05M Tris-HCl bufferを用いた。
Then, using the absorbance (OD 415 ) measured in Examples 1 to 3 and Comparative Example 1, the elastase activity of each of the silicon in Examples 1 to 3 was calculated according to the following formula.
Elastase activity rate (%) = (S - SB) x 100 / (C - CB)
Here, S is the absorbance of the test substance measured in Examples 1 to 3, SB is the absorbance of the blank of the test substance in Examples 1 to 3, C is the absorbance of the control measured in Comparative Example 1, and CB is the absorbance of the blank of the control in Comparative Example 1. In the blank, 0.05 M Tris-HCl buffer was used instead of elastase enzyme.

[Effect of silicon on the expression of collagen decomposition enzyme 1 gene (MMP1)]
Example 9
First, the water-soluble silicon "umo" was added to purified water and mixed to prepare a test substance having a concentration of water-soluble silicon "umo" of 1 mass % just before use.
Next, 5.0×10 5 cells/2 mL of NB1RGB cells (RIKEN BRC, Japan) were seeded on a 35 mm dish and cultured for 24 hours in a CO 2 incubator (CO 2 concentration 5%, 37° C.). Then, the medium was removed, and the medium containing the test substance prepared just before use was added, followed by culture for 24 hours in a CO 2 incubator.
そして、PureLink(登録商標)RNA Mini Kit(Cat No.12183018A,Invitrogen,USA)を用いて、以下で述べるRNA抽出・精製を行った。
具体的には、24時間培養後の培地を除去し、35mmディッシュを、37℃に加温した2mLのPBSで2回洗浄した。そして、さらに600μLの2M Dithiothreitol(CAS No.27565-41-9,Invitrogen,USA)含有Lysis Bufferを添加して細胞を溶解させて、ライセートを回収した。
そして、そのライセート中に存在する細胞を、Homogenizer(Cat No.12183-026,Invitrogen,USA)により破砕した。
そして、その細胞破砕液に、600μLの70%エタノール(CAS No.64-17-5,Japan alcohol,Japan)溶液を加え、シリカメンブレン付きカラムに移した。そして、12000×g及び室温で、1秒間遠心した。そして、ろ液を廃棄した。

そして、そのRNAの一部を、UV透過性96ウェルプレート (Cat No.8404,Thermo Scientific,USA)に分取し、Tris-EDTA Buffer (TE (pH8.0),Cat No.310-90023,NIPPON GENE,Japan) により25倍希釈し、マイクロプレートリーダー (SPARK(登録商標)10M TECAN,Switzerland) を用いて230nm、260nm及び280nmの吸光度(OD230,OD260及びOD280)を測定した。
そして、被験物質のRNA濃度を次式により計算し、TE Bufferにより希釈し、RNAの濃度を10μg/mLに調製した。
RNA濃度(μg/mL) =A×K×0.3×10(希釈倍率)
ここで、Aは被験物質のOD260であり、K=40(RNAの吸光係数)であり、l=0.3(光路長(cm))である。
Then, RNA extraction and purification was carried out as described below using PureLink (registered trademark) RNA Mini Kit (Cat No. 12183018A, Invitrogen, USA).
Specifically, the medium after 24 hours of culture was removed, and the 35 mm dish was washed twice with 2 mL of PBS heated to 37° C. Then, 600 μL of lysis buffer containing 2 M dithiothreitol (CAS No. 27565-41-9, Invitrogen, USA) was added to lyse the cells, and the lysate was collected.
Then, the cells present in the lysate were disrupted using a Homogenizer (Cat No. 12183-026, Invitrogen, USA).
Then, 600 μL of 70% ethanol (CAS No. 64-17-5, Japan alcohol, Japan) solution was added to the cell lysate, which was then transferred to a column with a silica membrane, and centrifuged at 12,000×g and room temperature for 1 second. The filtrate was then discarded.
Then, 700 μL of guanidine isothiocyanate-containing Wash Buffer I and 500 μL of ethanol-containing Wash Buffer II were added to the silica membrane for washing.
Then, the mixture was centrifuged at 12,000×g at room temperature for 15 seconds and then dried.
Then, 30 μL of RNase-Free Water was added, the mixture was left to stand at room temperature for 1 minute, and centrifuged at 12,000×g and room temperature for 15 seconds. This operation was repeated twice to elute RNA from the silica membrane.
A portion of the RNA was then dispensed into a UV-transparent 96-well plate (Cat No. 8404, Thermo Scientific, USA) and diluted 25-fold with Tris-EDTA Buffer (TE (pH 8.0), Cat No. 310-90023, NIPPON GENE, Japan), and the absorbance at 230 nm, 260 nm, and 280 nm (OD 230 , OD 260 , and OD 280 ) was measured using a microplate reader (SPARK® 10M TECAN, Switzerland).
The RNA concentration of the test substance was then calculated using the following formula, and diluted with TE buffer to adjust the RNA concentration to 10 μg/mL.
RNA concentration (μg/mL) = A x K x 0.3 x 10 (dilution ratio)
where A is the OD 260 of the test substance, K=40 (extinction coefficient of RNA), and 1=0.3 (path length (cm)).
次に、SuperScriptTM IV VILOTM Master Mix with ezDNase (Cat NO.11766050,Invitrogen,USA) により、RNAの逆転写を行った。
具体的には、8連チューブ (AB1182, Thermo Scientific,USA) に、1ウェルあたり1μLの10×ezDNase Buffer、1μLのezDNaseenzyme、6μLのNuclease-free Water及び2μLの10μg/mL RNAを加え、それを37℃で2分間培養した。
そして、2分後、8連チューブに、1ウェルあたり4μLのSuperScriptTM IV VILOTM Master Mix及び6μL Nuclease-free Waterを添加し、リアルタイムPCR (QuantStudio(登録商標)3, Applied Biosystems,USA) を用いて、25℃で10分間、50℃で10分間、及び85℃で5分間加熱し、cDNAを合成した。
そして、PCRプレート (Cat No.8010560,Thermo Scientific,USA)に、1ウェルあたり10μL TaqMan(登録商標)Fast AdvancedMaster Mix(Cat No.4444557,Applied Biosystems,USA)、1μLのTaqman Gene Expressior、7μLのUltraPureTM Distilled Water(Invitrogen,Cat No.10977-15,USA)及び2μLのcDNAを加え、プレートシール(Cat No.4360954,Thermo Scientific,USA)で密封した。
そして、プレート遠心機で溶液をスピンダウンし、起泡を除去した。
そして、リアルタイムPCRシステムによりReal-Time qPCRを行い、被験物質における各遺伝子の蛍光シグナルが任意の閾値に達する時のサイクル数であるThreshold Cycle(Ct) 値を算出した。そして、内部標準遺伝子によりCt値を補正し、ΔCt値とした。そして、後述する対照のΔCt値の平均によりΔCt値を補正し、これをΔΔCt値とした。ΔΔCtによって1サイクルあたりの検出の差で2倍量の差となると仮定し、2-ΔΔCtに代入して対照の遺伝子発現量を1とした場合の被験物質の遺伝子(MMP1)発現量を求めた。被験物質の遺伝子(MMP1)発現量を、対応のあるt検定で有意差検定を行った。検定はいずれも両側で有意水準を5%未満とした(P<0.05、P<0.01、P<0.001)。
Next, reverse transcription of RNA was performed using SuperScript™ IV VILO™ Master Mix with ezDNase (Cat No. 11766050, Invitrogen, USA).
Specifically, 1 μL of 10×ezDNase Buffer, 1 μL of ezDNase enzyme, 6 μL of Nuclease-free Water, and 2 μL of 10 μg/mL RNA were added per well to an 8-tube array (AB1182, Thermo Scientific, USA), and the tubes were incubated at 37° C. for 2 minutes.
After 2 minutes, 4 μL of SuperScript™ IV VILO™ Master Mix and 6 μL of Nuclease-free Water were added per well to the 8-tube tubes, and the mixture was heated at 25° C. for 10 minutes, at 50° C. for 10 minutes, and at 85° C. for 5 minutes using a real-time PCR system (QuantStudio (registered trademark) 3, Applied Biosystems, USA) to synthesize cDNA.
Then, 10 μL of TaqMan® Fast Advanced Master Mix (Cat No. 4444557, Applied Biosystems, USA), 1 μL of Taqman Gene Expressior, 7 μL of UltraPure™ Distilled Water (Invitrogen, Cat No. 10977-15, USA), and 2 μL of cDNA were added per well to a PCR plate (Cat No. 8010560, Thermo Scientific, USA), and the plate was sealed with a plate seal (Cat No. 4360954, Thermo Scientific, USA).
The solution was then spun down in a plate centrifuge to remove any bubbles.
Then, Real-Time qPCR was performed using a real-time PCR system, and the threshold cycle (Ct) value, which is the number of cycles when the fluorescent signal of each gene in the test substance reaches an arbitrary threshold, was calculated. Then, the Ct value was corrected using an internal standard gene to obtain a ΔCt value. Then, the ΔCt value was corrected using the average ΔCt value of the control described below to obtain a ΔΔCt value. Assuming that the difference in detection per cycle due to ΔΔCt is a difference of two times the amount, the expression level of the gene (MMP1) of the test substance was obtained when the gene expression level of the control was set to 1 by substituting 2 −ΔΔCt . The expression level of the gene (MMP1) of the test substance was tested for significance using a paired t-test. The significance level of the test was set to less than 5% on both sides (P<0.05, P<0.01, P<0.001).

Then, 600 μL of lysis buffer containing 2 M dithiothreitol (CAS No. 27565-41-9, Invitrogen, USA) was further added to lyse the cells, and the lysate was collected.
Then, the cells present in the lysate were disrupted using a Homogenizer (Cat No. 12183-026, Invitrogen, USA).
Then, 600 μL of 70% ethanol (CAS No. 64-17-5, Japan alcohol, Japan) solution was added to the cell lysate, which was then transferred to a column with a silica membrane, and centrifuged at 12,000×g and room temperature for 15 seconds. The filtrate was then discarded.
