Description

本発明は、肌の弛み、シワ及び/又はコジワを改善する美肌用の経口摂取用組成物に関する。   The present invention relates to a composition for oral intake for beautifying skin that improves skin sag, wrinkles and / or wrinkles.

従来から、肌の弛み、シワ及びコジワを改善し、美しい肌を保つことは多くの人々が希望とするところであり、これらを目的とする種々の製品が開発されている。これらの製品は、一般には化粧品という形態で提供され皮膚に塗布されるものが多いが、他方においては経口的に摂取されることにより上記目的を達成しようとする製品もある。   Conventionally, many people have desired to improve skin slackness, wrinkles and wrinkles, and to keep beautiful skin, and various products for these purposes have been developed. Many of these products are generally provided in the form of cosmetics and applied to the skin. On the other hand, there are products that try to achieve the above-mentioned purpose by being taken orally.

ヒアルロン酸は、真皮層に多く存在し、皮膚の保湿性や弾力性に関与していることが知られている。そのため、皮膚の保湿性や弾力性の維持を目的にした、ヒアルロン酸を含有させた食品が幾つか開発されている(特許文献1、特許文献2参照)。   Hyaluronic acid is abundant in the dermis layer and is known to be involved in the moisture retention and elasticity of the skin. For this reason, several foods containing hyaluronic acid have been developed for the purpose of maintaining the moisture retention and elasticity of the skin (see Patent Document 1 and Patent Document 2).

L−アスコルビン酸類は、皮膚や粘膜の健康維持を助ける抗酸化ビタミンとして、或いは、抗酸化剤として経口摂取用の組成物に利用されている(特許文献3)。また、L−アスコルビン酸類は、メラニンの生成を抑制することから、美白用の化粧料にも使用されている(特許文献4)。また、L−アスコルビン酸類を利用した、コラーゲン産生増強用の組成物も提案されている(特許文献5)。しながら、特定の割合で、ヒアルロン酸とL−アスコルビン酸類とを経口的に摂取することにより、肌の弛み、シワ及び/又はコジワを改善する美肌効果が顕著に発揮されることについての報告はない。   L-ascorbic acids are used in compositions for oral intake as antioxidant vitamins that help maintain the health of skin and mucous membranes or as antioxidants (Patent Document 3). L-ascorbic acids are also used in whitening cosmetics because they suppress the production of melanin (Patent Document 4). A composition for enhancing collagen production using L-ascorbic acids has also been proposed (Patent Document 5). However, there is a report that the skin beautifying effect that improves skin slackness, wrinkles and / or wrinkles is remarkably exhibited by taking hyaluronic acid and L-ascorbic acid orally at a specific ratio Absent.

本発明は、肌の弛み、シワ及び/又はコジワを改善し、肌荒れの改善や肌のうるおいの向上を達成することができる経口摂取用の組成物を提供することを課題とする。   An object of the present invention is to provide a composition for oral intake that can improve skin looseness, wrinkles and / or wrinkles, and can achieve improvement of rough skin and improvement of moisture of the skin.

本発明者は、上記課題を解決するために、鋭意研究した結果、特定の割合でヒアルロン酸およびL−アスコルビン酸類を併せて経口的に摂取すると、効果的に美しい肌を保つことができることを見出し、本発明を完成した。すなわち、本発明は、ヒアルロン酸とL−アスコルビン酸に換算したときのL−アスコルビン酸類との配合割合が、質量比で1:4乃至4:1である経口摂取用組成物を提供することにより上記課題を解決するものである。   As a result of earnest research to solve the above problems, the present inventor has found that when hyaluronic acid and L-ascorbic acids are taken orally in a specific ratio, beautiful skin can be effectively maintained. The present invention has been completed. That is, the present invention provides a composition for oral consumption in which the blending ratio of hyaluronic acid and L-ascorbic acid when converted to L-ascorbic acid is 1: 4 to 4: 1 by mass ratio. The present invention solves the above problems.

本発明の経口摂取用組成物は経口摂取することにより、摂取した者の、肌の弛み、シワ及び/又はコジワを改善すると共に、角層のバリア機能を改善し、皮膚の保水力を高め、肌荒れの改善、肌のうるおいが向上し、美しい肌が保持される。   The composition for oral ingestion of the present invention, when orally ingested, improves the slackness, wrinkles and / or wrinkles of the ingested person, improves the barrier function of the stratum corneum, and enhances the water retention capacity of the skin, Improves rough skin, improves moisture and keeps beautiful skin.

本発明の経口摂取用組成物に使用するヒアルロン酸は、化学合成されたものでもよく、発酵法で製造したものや、動物の組織や微生物等から抽出したものであっても良い。ヒアルロン酸は、本発明の効果を妨げない限り、必ずしも精製または単離されたものを用いる必要はなく、未分離組成物としての形態、それらを部分精製、或いは、高度に精製したものであってもよい。また、本発明の経口摂取用組成物に含まれるヒアルロン酸は、その少なくとも一部がヒアルロン酸ナトリウムなどの塩の形態になっていてもよい。   The hyaluronic acid used in the composition for oral ingestion of the present invention may be chemically synthesized, may be produced by fermentation, or may be extracted from animal tissues or microorganisms. Hyaluronic acid does not necessarily need to be purified or isolated as long as it does not interfere with the effects of the present invention, and is in the form of an unseparated composition, partially purified or highly purified. Also good. Moreover, at least a part of the hyaluronic acid contained in the composition for oral consumption of the present invention may be in the form of a salt such as sodium hyaluronate.

本発明の経口摂取用組成物に含まれるヒアルロン酸の含有量は、特に制限はなく、通常は、該組成物全質量に対して0.1質量%乃至25質量%であることが好ましい。   There is no restriction | limiting in particular in content of the hyaluronic acid contained in the composition for oral intake of this invention, Usually, it is preferable that it is 0.1 mass% thru | or 25 mass% with respect to this composition total mass.

本発明で使用するL−アスコルビン酸類としては、経口摂取が可能で、生体内において、ビタミンCとしての生理機能を発揮できるものであれば、特に限定されない。具体的には、例えば、L−アスコルビン酸や、L−アスコルビン酸配糖体、L−アスコルビン酸脂肪酸エステル、L−アスコルビン酸リン酸エステルなどのL−アスコルビン酸の誘導体、ニコチン酸アミド−Lアスコルビン酸複合体、これらL−アスコルビン酸類のアルカリ金属塩又はアルカリ土類金属塩の他、アンモニウム塩、アミノ酸塩等の塩も同様に使用することができる。なかでも、L−アスコルビン酸配糖体の1種であるL−アスコルビン酸2−グルコシドは、経口摂取用組成物に配合しても安定であるばかりでなく、経口摂取すると、生体内で徐々に分解されて、持続的にビタミンC作用を発揮し、ヒアルロン酸と組み合わせた場合には、他のL−アスコルビン酸類に比して、強い美肌作用を持続することができるので、特に望ましい。   The L-ascorbic acid used in the present invention is not particularly limited as long as it can be taken orally and can exhibit physiological functions as vitamin C in vivo. Specifically, for example, L-ascorbic acid, L-ascorbic acid glycosides, L-ascorbic acid fatty acid esters, L-ascorbic acid phosphates and other derivatives of L-ascorbic acid, nicotinamide-L ascorbine In addition to acid complexes and alkali metal salts or alkaline earth metal salts of these L-ascorbic acids, salts such as ammonium salts and amino acid salts can also be used. Among them, L-ascorbic acid 2-glucoside, which is one of L-ascorbic acid glycosides, is not only stable even when blended in an oral intake composition, but gradually in vivo when ingested. When it is decomposed and continuously exerts vitamin C action and is combined with hyaluronic acid, it is particularly desirable because it can maintain a strong skin beautifying action compared to other L-ascorbic acids.

本発明の経口摂取用組成物に含まれるL−アスコルビン酸類の含有量は、特に制限はなく、通常は、L−アスコルビン酸に換算して、該組成物全質量に対して0.1質量%乃至25質量%であることが好ましい。   The content of L-ascorbic acid contained in the composition for oral consumption of the present invention is not particularly limited, and is usually 0.1% by mass in terms of the total mass of the composition in terms of L-ascorbic acid. It is preferable that it is thru | or 25 mass%.

本発明の経口摂取用組成物におけるヒアルロン酸とL−アスコルビン酸類との配合割合は、本発明の所期の作用効果が達成できればよく、ヒアルロン酸とL−アスコルビン酸に換算したときのL−アスコルビン酸類との配合割合が、質量比で1:4乃至4:1、望ましくは1:2乃至2:1のものが、美肌効果の点で優れている。   The blending ratio of hyaluronic acid and L-ascorbic acid in the composition for oral consumption of the present invention is only required to achieve the intended effect of the present invention. L-ascorbine when converted to hyaluronic acid and L-ascorbic acid A compounding ratio with acids is 1: 4 to 4: 1, preferably 1: 2 to 2: 1 in terms of mass ratio, which is excellent in terms of skin beautifying effect.

また、このヒアルロン酸とL−アスコルビン酸類との経口摂取は、これらの2成分を含む組成物を摂取することが望ましいが、ヒアルロン酸とL−アスコルビン酸に換算したときのL−アスコルビン酸類との摂取割合が、質量比で1:4乃至4:1となるように、各々の成分を、別々に経口摂取する場合も、本発明に含まれる。   Moreover, although it is desirable to ingest these hyaluronic acid and L-ascorbic acids with a composition containing these two components, the hyaluronic acid and the L-ascorbic acids when converted to L-ascorbic acid are preferable. The case where each component is orally ingested separately so that the ingestion ratio is 1: 4 to 4: 1 by mass ratio is also included in the present invention.

<実験例1:ヒアルロン酸及び/又はL−アスコルビン酸類の経口摂取の肌に及ぼす影響>
ヒアルロン酸及び/又はL−アスコルビン酸類の経口摂取の肌に及ぼす影響を調べる試験を以下のように行った。すなわち、ヒアルロン酸と、L−アスコルビン酸、L−アスコルビン酸2−グルコシド(株式会社林原商事販売、商品名「アスコフレッシュ」)、L−アスコルビン酸脂肪酸エステル、滑潤剤としてショ糖脂肪酸エステル、及び、賦形剤として精製マルトース(株式会社林原商事販売、商品名「サンマルトS」)を、表1に示す質量比で混合して、全量を10質量部として、これを常法により打錠して、各々0.3g/錠の錠剤を調製した。その各々の配合の錠剤につき、各々17名の被験者に、1日当たり6錠を、3ヶ月間経口摂取させた。各々の被験者について、肌の状態を、下記評価方法1乃至評価方法3を用いて評価し、その結果を表1に示す。なお、L−アスコルビン酸2−グルコシド及びL−アスコルビン酸脂肪酸エステルの配合量は、L−アスコルビン酸に換算した量を表1に示した。なお、陰性対照として、これらの錠剤を摂取しなかった被験者17名についても、同様に評価を行い、その結果を併せて表1に示す。
<評価方法1>
摂取前、摂取2ヵ月後及び3ヵ月後に頬の角層水分蒸散量をTEWAメーター(テヴァメーター)により測定した。配合例毎に被験者17名の頬からの角層水分蒸散量の平均値を求めた。
<評価方法2>
各々の被験者を、摂取前及び摂取3ヵ月後に、角層の重層剥離の程度について観察し、摂取前に比してどのような変化が認められたかを、5段階にスコア化した(1:減少した、2:少し減少した、3:変化無し、4:少し増加した、5:増加した)。各配合の錠剤を摂取した17名の被験者ごとにスコアの平均を求めた。
<評価方法3>
各々の被験者から、摂取3ヵ月後に肌のかさつきの程度と、肌の弛み、シワ及びコジワの変化についてのアンケート調査を行った。それぞれの項目に関して改善を自覚した者の割合を改善率とした。
<Experimental Example 1: Effect of oral intake of hyaluronic acid and / or L-ascorbic acid on skin>
A test for examining the effect of oral intake of hyaluronic acid and / or L-ascorbic acid on the skin was performed as follows. That is, hyaluronic acid, L-ascorbic acid, L-ascorbic acid 2-glucoside (sales by Hayashibara Corporation, trade name “ASCOFRESH”), L-ascorbic acid fatty acid ester, sucrose fatty acid ester as a lubricant, and Purified maltose (trade name “Sanmalto S”, sold by Hayashibara Co., Ltd.) as an excipient was mixed at a mass ratio shown in Table 1, and the total amount was 10 parts by mass. Each tablet was prepared at 0.3 g / tablet. For each tablet of each formulation, 17 subjects each took 6 tablets per day for 3 months. For each subject, the skin condition was evaluated using the following evaluation methods 1 to 3, and the results are shown in Table 1. In addition, the compounding quantity of L-ascorbic acid 2-glucoside and L-ascorbic acid fatty acid ester showed the quantity converted into L-ascorbic acid in Table 1. As a negative control, 17 subjects who did not take these tablets were similarly evaluated, and the results are shown in Table 1.
<Evaluation method 1>
Before ingestion, 2 months after ingestion and 3 months later, the amount of transpiration of the stratum corneum in the cheek was measured with a TEWA meter (Tevameter). The average value of the horny layer moisture transpiration from the cheeks of 17 subjects was determined for each formulation example.
<Evaluation method 2>
Each subject was observed for the degree of delamination of the stratum corneum before ingestion and after 3 months of ingestion, and the change observed compared to before ingestion was scored in 5 stages (1: decrease) 2: slightly decreased, 3: no change, 4: increased slightly, 5: increased). The average score was calculated for each of 17 subjects who took tablets of each formulation.
<Evaluation method 3>
Each subject conducted a questionnaire survey on the degree of skin roughness, skin looseness, wrinkles and changes in wrinkles 3 months after ingestion. The percentage of those who were aware of improvement in each item was taken as the improvement rate.

Figure 2007063177
Figure 2007063177

<結果>
表1から明らかなよう、ヒアルロン酸或いはL−アスコルビン酸類を単独で摂取した場合(配合No.1乃至配合No.4)には、頬からの水分蒸散量、角層の重層剥離の程度、肌のかさつきの程度、肌の弛み、シワ及びコジワを改善の程度の何れにおいても、摂取前に比して変化は認められなかった。これに対して、ヒアルロン酸とL−アスコルビン酸類を等質量配合した錠剤を摂取した場合(配合No.5乃至配合No.7)には、評価に使用した何れの項目においても、摂取前に比して改善が認められた。また、ヒアルロン酸と組み合わせるL−アスコルビン酸類としては、L−アスコルビン酸2−グルコシドを使用した場合に最も強い改善効果が認められた。
<Result>
As is clear from Table 1, when hyaluronic acid or L-ascorbic acid was ingested alone (Formulation No. 1 to No. 4), the amount of water transpiration from the cheeks, the degree of exfoliation of the stratum corneum, and the skin No change was observed in any of the degree of bulkiness, skin looseness, wrinkles and wrinkles to improve. On the other hand, when taking tablets containing equal amounts of hyaluronic acid and L-ascorbic acid (formulation No. 5 to No. 7), any of the items used for evaluation were compared with those before ingestion. Improvement was observed. Moreover, as L-ascorbic acid combined with hyaluronic acid, the strongest improvement effect was recognized when L-ascorbic acid 2-glucoside was used.

<実験例2:ヒアルロン酸及びL−アスコルビン酸類の摂取量の及ぼす肌への影響>
ヒアルロン酸及びL−アスコルビン酸類の摂取量の及ぼす肌への影響を調べる実験を以下のようにして行った。即ち、実験例1で調製した配合No.6のヒアルロン酸とL−アスコルビン酸2−グルコシドとを等質量配合した錠剤を使用して、1日当たり、1錠、2錠、3錠、4錠、5錠、或いは6錠の何れかを、各々17名の被験者に2ヶ月間摂取させた。各々の被験者について、実験終了時の、被験者の頬の皮膚の状態を、実験例1と同じ評価方法1乃至評価方法3を用いて評価し、その結果を表2に示す。なお、実験例2と実験例1とは、被験者が重複しないように実験を行った。
<Experimental Example 2: Effects on the skin of hyaluronic acid and L-ascorbic acid intake>
An experiment for examining the effect on the skin of the intake of hyaluronic acid and L-ascorbic acid was performed as follows. That is, the formulation No. prepared in Experimental Example 1 was obtained. 6 tablets of hyaluronic acid and L-ascorbic acid 2-glucoside in an equal mass are used, and one tablet, two tablets, three tablets, four tablets, five tablets, or six tablets per day, Each of 17 subjects ingested for 2 months. For each subject, the condition of the subject's cheek skin at the end of the experiment was evaluated using the same evaluation methods 1 to 3 as in Experimental Example 1, and the results are shown in Table 2. In addition, the experiment example 2 and the experiment example 1 were conducted so that the subjects did not overlap.

Figure 2007063177
Figure 2007063177

表2から明らかなように、錠剤を1日当たり1錠摂取した場合には、評価に使用した何れの項目においても、摂取前に比して改善は認められなかった。これに対して、1日当たり、2錠を摂取した場合には、評価に使用した何れの項目においても、摂取前に比して改善が認められ、その改善は、1日当たり3錠以上の摂取で顕著であった。   As is apparent from Table 2, when one tablet was taken per day, no improvement was observed in any of the items used for the evaluation as compared to before the intake. On the other hand, when taking 2 tablets per day, improvement was observed in all items used for evaluation compared to before taking, and the improvement was achieved by taking 3 tablets or more per day. It was remarkable.

<実験例3:経口摂取用組成物中のヒアルロン酸とL−アスコルビン酸類との配合割合の肌に及ぼす影響>
実験例1で、ヒアルロン酸とL−アスコルビン酸類とを組み合わせて経口摂取することにより、肌の弛み、シワ及びコジワが改善されることが確認されたので、経口摂取用組成物中のヒアルロン酸とL−アスコルビン酸類との配合割合の肌に及ぼす影響を調べる試験を以下のように行った。すなわち、ヒアルロン酸と、L−アスコルビン酸2−グルコシド(株式会社林原商事販売、商品名「アスコフレッシュ」)、ショ糖脂肪酸エステル、賦形剤として精製マルトース(株式会社林原商事販売、商品名「サンマルトS」)を表3に示す質量比で混合して、全量を10質量部とし、これを常法により打錠して、各々0.3g/錠の錠剤を調製した。その各々の配合につき、各々17名の被験者に、1日当たり6錠、3ヶ月間経口摂取させた。各々の被験者について、実験終了時の被験者の肌の状態を、実験例1と同じ評価方法1乃至評価方法3を用いて評価し、その結果を表3に示す。なお、L−アスコルビン酸2−グルコシドの配合量は、L−アスコルビン酸に換算した量を表3に示した。なお、実験例3と、実験例1、実験例2とは、何れも被験者が重複しないように実験を行った。

Ingestion of tablets formulated at a ratio of (No. 5 to No. 7), the amount of transpiration of keratin used in the evaluation, the degree of exfoliation of the stratum corneum, the degree of skin roughness, Improvement was recognized in any of the items of improvement of sagging, wrinkles and wrinkles. On the other hand, hyaluronic acid and L-ascorbic acid were 0.1: 1.9 (formulation No. 1), 0.2: 1.8 (formulation No. 2), 1.8: 0.2 ( In the blending ratio of No. 10) or 1.9: 0.1 (blending No. 11), the skin looseness, wrinkles and wrinkles were all improved compared to before intake. I couldn't.

これらの実験結果は、ヒアルロン酸とL−アスコルビン酸に換算したときのL−アスコルビン酸類とを、質量比で1:4乃至4:1の割合で、さらに望ましくは1:2乃至2:1の割合で配合した経口摂取用組成物が、肌の弛み、シワ及びコジワを改善し、潤いのある肌とする、優れた美肌作用を有していることを物語っている。   These experimental results show that hyaluronic acid and L-ascorbic acid converted to L-ascorbic acid are in a mass ratio of 1: 4 to 4: 1, more preferably 1: 2 to 2: 1. It indicates that the composition for oral intake formulated in a proportion has excellent skin-beautifying action that improves skin slackness, wrinkles and wrinkles, and makes the skin moist.
