Description
本発明は、皮膚外用剤、特に皮膚化粧料に有用な成分であるコラーゲンについて、従来知られている保湿効果、抗炎症効果などを損なうことなく、におい、呈色などの製剤上の問題を解決し、多量に配合することを可能にしたコラーゲン発酵液及びそれを配合した皮膚外用剤に関する。 INDUSTRIAL APPLICABILITY The present invention solves pharmaceutical problems such as odor and coloration of collagen, which is a useful ingredient for external skin preparations, especially skin cosmetics, without impairing the conventionally known moisturizing effect and anti-inflammatory effect. The present invention relates to a collagen fermented liquid that can be blended in a large amount and a skin external preparation containing the collagen fermented liquid.
コラーゲンは、三重らせん構造を有する分子量30万程度のタンパク質であり、体内において、骨・軟骨・皮膚等の各細胞同士を結合する細胞外基質として広く知られている。特に、コラーゲンのもつ弾力性に注目した皮膚美容・化粧料の分野においては、加齢・紫外線等による外部刺激による減少・変質や体内への吸収、生成促進などを課題とした研究・開発が進められている。 Collagen is a protein having a triple helix structure and a molecular weight of about 300,000, and is widely known as an extracellular matrix that binds cells such as bone, cartilage, and skin to each other in the body. In particular, in the field of skin cosmetology and cosmetics, which focuses on the elasticity of collagen, research and development are proceeding with issues such as aging, reduction due to external stimuli such as ultraviolet rays, deterioration, absorption into the body, and promotion of production. Has been done.
一方で、コラーゲンは、その利用に際して、素材特性に依拠した課題を有している。すなわち、その巨大な分子量から皮膚・経口問わず吸収し難い点、溶解性に難があり製剤上不安定である点、特に動物系原料において顕著な独特の臭気や色を有する点などがよく知られている。 On the other hand, collagen has a problem depending on the material characteristics when it is used. In other words, it is well known that due to its huge molecular weight, it is difficult to absorb regardless of whether it is skin or oral, it is difficult to dissolve and it is unstable in the formulation, and it has a distinctive unique odor and color, especially in animal-based raw materials. Has been done.
これらの課題に対し、利用目的に応じて、物理・化学・生物的な手法をもって分解して分子量を小さくする方法、分子の一部を変性(化学修飾)して水性または/及び油性溶媒に対する溶解度を上げる方法、原料素材に対して前処理を施し脱色や臭気を軽減する方法などを用途等に応じて適宜採用している。 To solve these problems, depending on the purpose of use, a method of decomposing by physical, chemical, or biological methods to reduce the molecular weight, or a method of modifying (chemically modifying) a part of the molecule to make it soluble in an aqueous or / or oily solvent. A method of raising the temperature, a method of pretreating the raw material to reduce decolorization and odor, etc. are appropriately adopted according to the application.
しかしながら、非特許文献1の処方例でも明らかなように、皮膚外用剤、特に皮膚化粧料分野において利用する際の配合量には限度があり、1/3、1/2といった割合に至るような大量の配合を実現することはできていなかった。 However, as is clear from the prescription example of Non-Patent Document 1, there is a limit to the blending amount when used in the field of external skin preparations, especially in the field of skin cosmetics, and the ratio may reach 1/3 or 1/2. It was not possible to achieve a large amount of compounding.
ところで、皮膚外用剤、特に皮膚化粧料分野において、近年「発酵物」が特に注目されている。これは、微生物の働きかけにより素材に変化を生じせしめるもので、素材を分解させる方法、例えば、ヒアルロン酸など特定の成分物質や植物抽出物のような成分構成が一定ではない混合物を素材として、乳酸菌などの菌類や酵母などの広義の微生物の働きかけにより分解したものが知られている。 By the way, in recent years, "fermented products" have attracted particular attention in the field of external skin preparations, especially skin cosmetics. This is a method of decomposing the material by the action of microorganisms, for example, lactic acid bacteria using a specific component substance such as hyaluronic acid or a mixture such as a plant extract whose component composition is not constant. It is known that it is decomposed by the action of fungi such as yeast and microorganisms in a broad sense such as yeast.
このとき、微生物の生育に必要な炭素源、窒素源などの栄養源、その他の必要成分を添加した培養プロセスにより分解などの化学変化を促す方法が一般的であり、必要に応じて予備培養等の前処理もあわせて実施することもある。 At this time, a method of promoting chemical changes such as decomposition by a culture process in which nutrient sources such as carbon sources and nitrogen sources necessary for the growth of microorganisms and other necessary components are added is common, and pre-culture or the like is necessary. Pretreatment may also be carried out.
ところが、同じ素材であっても、微生物の種類、補充する栄養源その他の添加物や、温度、培養期間などの各要素によって、得られる生成物が異なること、そして、生成物は目的物と異なる夾雑物を含有すること、さらに培養の各要素を管理してさえ、その生成物の構成は変動しがちであり、一定とすることは難しいことから、抽出、分画その他の手法を併用し目的とする成分、または組成物を得ることが一般的である。 However, even if the same material is used, the obtained product differs depending on the type of microorganism, the nutrient source to be supplemented and other additives, the temperature, the culture period, and the like, and the product is different from the target product. Since the composition of the product tends to fluctuate and is difficult to keep constant even if it contains impurities and even if each element of the culture is managed, the purpose is to use extraction, fractionation and other methods together. It is common to obtain the ingredients or compositions to be used.
「発酵物」は、一般的には、このように微生物により素材を発酵させた生成物そのもの、または、ゴミや沈殿物をろ過する程度の軽度の後処理を経た複数成分からなる混合物または組成物を指しており、本発明においてもこの定義を援用する。
従って、「発酵物」は、素材、前処理を含む培養プロセス、後処理によって、おおよその成分構成は定まるものの、その本質は、不定成分が不定割合で存在する混合物であり、具体的に構成を特定することが難しい上に非現実的である。
A "fermented product" is generally the product itself, which is obtained by fermenting the material with microorganisms in this way, or a mixture or composition consisting of a plurality of components which has undergone a light post-treatment such as filtering dust or precipitate. This definition is also used in the present invention.
Therefore, although the "fermented product" has an approximate composition of components determined by the material, the culture process including pretreatment, and the post-treatment, the essence of the "fermented product" is a mixture in which indefinite components are present in an indefinite proportion. It is difficult and unrealistic to identify.
非特許文献1には、海藻の繊維分解酵素による分解液または酸化分解液に栄養源をあたえ、酵母または乳酸菌で発酵させた抽出液またはそれを乾燥させたものを配合した化粧料が記載されている。 Non-Patent Document 1 describes a cosmetic containing a nutrient source added to a decomposition solution or an oxidative decomposition solution of seaweed using a fibrous degrading enzyme, fermented with yeast or lactic acid bacteria, or a dried product thereof. There is.
非特許文献2には、ベニバナの花弁を熱水で抽出して固形分を除去して得られるベニバナ抽出エキスをそのままサッカロミケス目(Saccharomycetales)ピキア属(Pichia)ピキア・クドリアヴゼヴィイ(Pichia kudriavzevii)の酵母で発酵して得られる、線維芽細胞増殖用ベニバナ発酵液が記載されている。 In Non-Patent Document 2, the petals of Benibana are extracted with hot water to remove solids, and the extracted Benibana extract is used as it is in the order Saccharomycetales, Pichia, and Pichia kudriavzevi. ) Fermented Benibana fermented liquor for proliferation of fibroblasts, which is obtained by fermentation with yeast.
非特許文献3には、サンシュユ果実、コメヌカとベニコウジ菌を混合して発酵させた発酵液をプロテアーゼ処理して得られるコラーゲン産生作用を呈する組成物が記載されている。 Non-Patent Document 3 describes a composition exhibiting a collagen-producing action obtained by performing a protease treatment on a fermented liquid obtained by mixing and fermenting Cornus officinalis fruit, Monascus purpureus and Monascus purpureus.
非特許文献1には、当業者によって、様々な原料の配合に基づいた様々な剤型の皮膚外用剤の一種であるスキンケア・メイク化粧料組成物が提案されている。 In Non-Patent Document 1, a person skilled in the art proposes a skin care / make-up cosmetic composition which is a kind of skin external preparation of various dosage forms based on the combination of various raw materials.
しかしながら、皮膚外用剤、特に皮膚化粧料に有用な成分であるコラーゲンについて、従来知られている保湿効果、抗炎症効果などを損なうことなく、におい、呈色などの製剤上の問題を解決し、多量に配合することを可能にしたコラーゲン発酵液及びそれを配合した皮膚外用剤(本発明の効果・特徴)への応用可能性について記載または示唆されたものは存在しなかった。 However, collagen, which is a useful ingredient for external skin preparations, especially skin cosmetics, solves pharmaceutical problems such as odor and coloration without impairing the conventionally known moisturizing effect and anti-inflammatory effect. There was no description or suggestion of applicability to a collagen fermented liquid that could be blended in a large amount and a skin external preparation (effect / feature of the present invention) containing the collagen fermented liquid.
このような背景から、安定性及び安全性が良好で、長期間連続して使用することができ、従来知られている保湿効果、抗炎症効果などを損なうことなく、におい、呈色などの製剤上の問題を解決し、多量に配合可能なコラーゲン発酵液及びそれを配合した皮膚外用剤が求められていた。 Against this background, it has good stability and safety, can be used continuously for a long period of time, and is a formulation such as odor and coloration without impairing the conventionally known moisturizing effect and anti-inflammatory effect. There has been a demand for a collagen fermented liquid that can be blended in a large amount and a skin external preparation containing the collagen fermented liquid that solves the above problems.
発明者らは、コラーゲン類そのものではなく、これをサッカロミセス属酵母によって発酵させた培養液、好ましくは、培養培地に添加する糖類がショ糖及び/又は果糖を使用することで、安定性及び安全性が良好で、長期間連続して使用することができ、従来知られている保湿効果、抗炎症効果などを損なうことなく、におい、呈色などの製剤上の問題を解決し、さらに多量に配合可能なコラーゲン発酵液を配合した皮膚外用剤を得ることが出来ることに気づき発明を完成した。 The inventors have found that the sucrose and / or fructose is used as the saccharide added to the culture medium, preferably the culture medium obtained by fermenting the collagens with the yeast of the genus Saccharomyces, rather than the collagens themselves, for stability and safety. It is good and can be used continuously for a long period of time, solves formulation problems such as odor and coloration without impairing the conventionally known moisturizing effect, anti-inflammatory effect, etc. He realized that it was possible to obtain a skin external preparation containing a possible collagen fermented liquid, and completed the invention.

次に、コラーゲン発酵液の効果検証結果を示す。
検証にあたっては、モニター官能評価によるものとした。
具体的には、従業員から選抜した健常な皮膚を有する男女各3名のモニターを選出し、実施例2の化粧水処方構成をベースとするコラーゲン発酵液の配合量が5重量パーセントと80重量パーセントのものの2種のサンプルを複数回使用させ、化粧料、特にスキンケア化粧料において訴求されコラーゲンの大量配合が求められる「保湿感」と大量配合によって低下する「使用感」について評価した。
このとき、「保湿感」は、使用前を含めて「肌のうるおい」「肌のなめらかさ」「肌のやわらかさ」を評価し、「使用感」は、「べたつき」「におい」について評価した。
評価は、「肌のうるおい」「肌のなめらかさ」「肌のやわらかさ」については「1.感じない、2.あまり感じない、3.どちらともいえない、4.やや感じる、5.感じる」の5段階評価、「べたつき」「におい」については「1.気にならない 2.あまり気にならない 3.どちらともいえない 4.やや気になる 5.気になる」の5段階で評価し、その平均値を採用した。
Next, the effect verification result of the collagen fermented liquid is shown.
The verification was based on monitor sensory evaluation.
Specifically, three monitors for each of men and women with healthy skin selected from employees were selected, and the amount of collagen fermented liquid based on the lotion formulation composition of Example 2 was 5% by weight and 80% by weight. Two kinds of samples of% were used multiple times, and the "moisturizing feeling" that was appealed in cosmetics, especially skin care cosmetics and required a large amount of collagen to be mixed, and the "feeling of use" that was reduced by the large amount of collagen were evaluated.
At this time, "moisturizing feeling" was evaluated for "skin moisture", "skin smoothness" and "skin softness" including before use, and "usability" was evaluated for "stickiness" and "smell". ..
The evaluation was "1. I don't feel, 2. I don't feel much, 3. I can't say either, 4. I feel a little, 5. I feel" about "moisturizing skin", "smoothness of skin", and "softness of skin". For "stickiness" and "smell", evaluate on a 5-point scale of "1. I don't care 2. I don't care much 3. I can't say either 4. I'm a little worried 5. I'm worried" The average value was adopted.
さらに、実施例2乃至4の調剤サンプル及びモニター評価に用いたサンプル2種について、40°C・3ヶ月の安定性試験を実施したところ、
モニター評価サンプルの80%配合品について、極微呈色が生じることが観察された。その後の進行が見られなかったこと、及び製品としての支障はないレベルであることから、ほぼ配合上の上限であることが示唆されるものの、充分な安定性を維持していることがわかる。
Furthermore, when the dispensing sample of Examples 2 to 4 and the two samples used for the monitor evaluation were subjected to a stability test at 40 ° C. for 3 months, the stability test was carried out.
It was observed that a slight coloration occurred in the 80% compounded product of the monitor evaluation sample. Since no further progress was observed and the level did not hinder the product, it is suggested that the upper limit of the formulation is almost the same, but it can be seen that sufficient stability is maintained.
本発明の皮膚外用剤は、外用化粧品としてメーキャップ化粧品やスキンケア化粧品(機能性化粧品)としてだけでなく、保湿効果をもつ機能性化粧品としても利用できる。また、薬事上の各種基準・要件を備えることによって、医薬部外品及び医薬品にも利用することができる。 The external skin preparation of the present invention can be used not only as makeup cosmetics and skin care cosmetics (functional cosmetics) as external cosmetics, but also as functional cosmetics having a moisturizing effect. In addition, it can be used for quasi-drugs and pharmaceuticals by providing various standards and requirements for pharmaceutical affairs.
