Abstract
Description
本発明は化粧用のゲルに関する。 The present invention relates to a cosmetic gel.
ゲルはコロイド次元の微粒子あるいは高分子溶質が分散して、分散質のネットワークにより高い粘性を持ち、流動性を失い、系全体としては固体状になったものをいう。また、ゲルのうち、分散媒が水のゲルをヒドロゲル (hydrogel)とも呼び、多糖類や高分子を用いたヒドロゲル（ハイドロゲルともいう）が各種用途に利用されている。
ローカストビーンガムは、マメ科植物カロブ樹の種子の胚乳部分等から得られる水溶性の多糖類である。ローカストビーンガムは加熱することで水に溶解する。溶解液は高粘性であり、造粘安定剤、保水剤としてとして食品や化粧料に利用されている。
またローカストビーンガムは、単独ではゲル化しないが、同じく単独ではゲル化しないキサンタンガムと組み合わせることによって、強固なゲルを形成することが知られている。しかしながら、キサンタンガムとローカストビーンガムから得られるゲルは、ナトリウムやカルシウムなどのイオンを含む場合、そのゲルが形成されないか、あるいはゲル強度が経時的に低下することが知られている。このため、塩類を配合する化粧料の用途に用いることが困難であった。
A gel is a gel in which colloidal fine particles or polymer solute is dispersed, has a high viscosity due to the dispersoid network, loses fluidity, and becomes solid as a whole system. In addition, among gels, a gel whose dispersion medium is water is also called a hydrogel, and hydrogels using polysaccharides or polymers (also called hydrogels) are used for various purposes.
Locust bean gum is a water-soluble polysaccharide obtained from the endosperm portion of the seeds of the legume plant carob tree. Locust bean gum dissolves in water when heated. The solution is highly viscous and is used in foods and cosmetics as a thickening stabilizer and water retention agent.
Locust bean gum is known to form a strong gel when combined with xanthan gum that does not gel by itself but also does not gel by itself. However, it is known that a gel obtained from xanthan gum and locust bean gum does not form the gel when it contains ions such as sodium and calcium, or the gel strength decreases with time. For this reason, it was difficult to use for the use of the cosmetics which mix | blend salts.
本発明は、電解質を配合しても安定なハイドロゲル（ゲル）を提供することを課題とする。 An object of the present invention is to provide a hydrogel (gel) that is stable even when an electrolyte is blended.
本発明者らは、ローカストビーンガムと、保湿剤としてポリオキシエチレンメチルグルコシドを併用すると安定なハイドロゲルを形成することを見出し、本発明をなした。このゲルは、化粧料に配合される塩類や電解質を含んでも安定なゲル構造を維持する。 The present inventors have found that a stable hydrogel is formed when locust bean gum is used in combination with polyoxyethylene methyl glucoside as a humectant, and the present invention has been made. This gel maintains a stable gel structure even if it contains salts and electrolytes blended in cosmetics.
本発明の主な構成は、次のとおりである。
（１）ローカストビーンガムとポリオキシエチレンメチルグルコシド又はポリオキシプロピレンメチルグルコシドを含有するゲル。
（２）ローカストビーンガム、ポリオキシエチレンメチルグルコシド又はポリオキシプロピレンメチルグルコシドが１：５〜１：１２の質量比率で含有されている（１）に記載のゲル。
（３）ゲル中のローカストビーンガムが０．５〜１．５質量％、ポリオキシエチレンメチルグルコシド又はポリオキシプロピレンメチルグルコシドが５〜１５質量％である（１）又は（２）に記載のゲル。
（４）ゲル中に電解質を含む（１）〜（３）のいずれかに記載のゲル。
（５）電解質がクエン酸、クエン酸ナトリウム、水酸化カリウム、アスコルビン酸２グルコシド、リン酸アスコルビルＭｇ、３−Ｏ−エチルアスコルビン酸、Ｌ−グルタチオン及びＬ−システインから選ばれる一種以上である（１）〜（４）のいずれかに記載のゲル。
（６）化粧料である（１）〜（５）のいずれかに記載のゲル。
（７）美容ゲルである（１）〜（６）のいずれかに記載のゲル。
The main configuration of the present invention is as follows.
(1) Gel containing locust bean gum and polyoxyethylene methyl glucoside or polyoxypropylene methyl glucoside.
(2) The gel according to (1), wherein locust bean gum, polyoxyethylene methyl glucoside or polyoxypropylene methyl glucoside is contained in a mass ratio of 1: 5 to 1:12.

(6) The gel according to any one of (1) to (5), which is a cosmetic.
(7) The gel according to any one of (1) to (6), which is a cosmetic gel.
本発明により、新規なハイドロゲル（本発明においては「ゲル」と略記する）が提供される。
本発明のゲルは、耐塩性を有している。また化粧料として用いた場合、ローカストビーンガムと、ポリオキシエチレンメチルグルコシド又はポリオキシプロピレンメチルグルコシドの保湿性をあわせもった好ましい使用感を付与できる。また耐塩性を有しているため、化粧料に必須の塩類やキレート成分を添加することが可能であり、新しい化粧料として有用である。また美容成分（電解質）を配合した美容ゲルとしても有用である。
The present invention provides a novel hydrogel (abbreviated as “gel” in the present invention).
The gel of the present invention has salt resistance. Moreover, when it uses as cosmetics, the preferable usability which combined the moisturizing property of locust bean gum and polyoxyethylene methyl glucoside or polyoxypropylene methyl glucoside can be provided. Moreover, since it has salt tolerance, it is possible to add essential salts and chelate components to cosmetics, and it is useful as a new cosmetic. It is also useful as a cosmetic gel containing a cosmetic component (electrolyte).
本発明は、ローカストビーンガム、ポリオキシエチレンメチルグルコシド又はポリオキシプロピレンメチルグルコシドから形成される新規なゲルであり、このゲルを利用した化粧料である。

以下に実施例、比較例を挙げて、本発明の特徴と効果をさらに詳細に説明する。 The features and effects of the present invention will be described in more detail with reference to examples and comparative examples.
表１の組成で、実施例１〜８のゲルを調製した。一方従来のローカストビーンガムとキサンタンガムにより形成されるゲルを、表２の組成で調製した。調製は、各成分を混合し、水を加えて撹拌しながら８０℃まで加熱して溶解液を調製し、この溶解液を室温に一晩放置した。なお電解質を添加した実施例７、８、比較例２〜４については、電解質は溶液の温度が３０℃に低下したとき添加した。なお表中の１．３ＢＧは１，３ブチレングリコールである。 Gels of Examples 1 to 8 were prepared with the compositions shown in Table 1. On the other hand, a gel formed of conventional locust bean gum and xanthan gum was prepared with the composition shown in Table 2. In the preparation, each component was mixed, water was added and heated to 80 ° C. with stirring to prepare a solution, and this solution was left at room temperature overnight. In Examples 7 and 8 and Comparative Examples 2 to 4 to which an electrolyte was added, the electrolyte was added when the temperature of the solution dropped to 30 ° C. In the table, 1.3BG is 1,3 butylene glycol.
実施例１〜８、比較例１はいずれも半透明〜透明なゲルを形成していた。比較例２〜４は調製直後にゲルが壊れていた。 Examples 1-8 and Comparative Example 1 all formed a translucent to transparent gel. In Comparative Examples 2 to 4, the gel was broken immediately after preparation.
ゲルの状態観察
直径４ｃｍの高さ４ｃｍのガラス製ジャー容器中に、各成分を混合しゲルを形成した直後の各試料を５０ｍｌ充填し、さらにこれを一昼夜静置した。次いで、この容器を傾けて、ゲルの形態がどのように変化するか観察した。耐塩性を有しないゲルの場合は、ゲルが不安定化するため、該容器を傾けた時の重力変化によってゲルが流動する。尚、この試験・評価は、化粧料容器に充填された状態で美しいゲル状の外観を保つ指標となる。
ゲルの状態は下記の基準により判断した。
（判定基準）
○：容器を傾けたとき、ゲルの形状をほぼ保っている。
△：容器を傾けたとき、ゲルが変形するが流動性はみられない。
×：容器を傾けたとき、流動性があり流れ落ちる。
ゲルの状態を観察した結果を下記表３に示す。
尚、比較例２〜４は調製直後にゲルが壊れていたが、容器に充填して一昼夜静置し観察した。
Observation of gel state In a glass jar 4 cm in diameter and 4 cm in height, 50 ml of each sample immediately after each component was mixed to form a gel was filled, and this was left still overnight. The container was then tilted to observe how the gel morphology changed. In the case of a gel that does not have salt tolerance, the gel becomes unstable, so that the gel flows due to gravity change when the container is tilted. This test / evaluation is an index for maintaining a beautiful gel-like appearance in a state where the cosmetic container is filled.
The state of the gel was judged according to the following criteria.
(Criteria)
○: When the container is tilted, the gel shape is almost maintained.
Δ: When the container is tilted, the gel is deformed but no fluidity is observed.
X: When the container is tilted, it flows and falls.
The results of observation of the gel state are shown in Table 3 below.
In Comparative Examples 2 to 4, although the gel was broken immediately after preparation, it was filled in a container and allowed to stand overnight for observation.
表３に示すとおり、本発明のゲルはキサンタンガムを併用しなくとも安定なゲルを形成した。また、耐塩性を有しており、ローカストビーンガムとキサンタンガムにより形成されるゲルが電解質によりゲルが不安定化するのに対して、本発明のゲルは安定であった。 As shown in Table 3, the gel of the present invention formed a stable gel without using xanthan gum. Moreover, it has salt tolerance and the gel of this invention was stable with respect to the gel formed by locust bean gum and xanthan gum destabilized by electrolyte.
＜参考例１＞
実施例、比較例で用いた１，３ブチレングリコールがゲル化に関与していないことを確認するため、ローカストビーンガムと１，３ブチレングリコールの溶解水溶液を一夜静置し、上記のゲルの状態観察と同様の試験を行った。試験結果を下記の表４に示す。
<Reference Example 1>
In order to confirm that 1,3 butylene glycol used in Examples and Comparative Examples is not involved in gelation, the solution of locust bean gum and 1,3 butylene glycol is allowed to stand overnight, and the gel state described above A test similar to the observation was performed. The test results are shown in Table 4 below.
表４のとおりローカストビーンガムと１，３ブチレングリコールの溶液は粘稠な溶液となるがゲル化はしていなかった。したがって、実施例１〜８のゲルは、ローカストビーンガムとポリオキシエチレンメチルグルコシドが共存することで形成されるゲルであることが明らかとなった。 As shown in Table 4, the solution of locust bean gum and 1,3 butylene glycol was a viscous solution but was not gelled. Therefore, it was revealed that the gels of Examples 1 to 8 were gels formed by the coexistence of locust bean gum and polyoxyethylene methyl glucoside.
＜参考例２＞
ローカストビーンガムと保湿剤として代表的なグリセリンを組み合わせることでゲル化するか確認した。ローカストビーンガムとグリセリンの溶解水溶液を一夜静置し、上記のゲルの状態観察と同様の試験を行った。試験結果を下記の表５に示す。
<Reference Example 2>
It confirmed whether it gelatinized by combining typical glycerin as locust bean gum and a moisturizer. A dissolved aqueous solution of locust bean gum and glycerin was allowed to stand overnight, and the same test as in the state observation of the gel was performed. The test results are shown in Table 5 below.
表５のとおりグリセリンはローカストビーンガムをゲル化しなかった。
As shown in Table 5, glycerin did not gel locust bean gum.
