Description
本発明は、葉藍の成分を含有する石けんとその製造方法に関する。 The present invention relates to a soap containing a leaf green component and a method for producing the same.
通常の石けんは、高級脂肪酸のアルカリ金属塩でできており、洗浄を目的に作られており、動植物油に水酸化ナトリウムや水酸化カリウム等を加えて、煮沸混合した後、冷却あるいは塩析等を行って固化、成形して製造される。しかし、最近の健康ブームで肌に優しい石けんが注目され、オリーブオイルやパームオイルなどの植物油に香料、着色剤のみならず、保湿性、抗菌性、抗アレルギー性など様々な薬効成分やハーブなどが添加された石けんが作られている。
例えば、入浴、洗顔に用いる肌に優しいミネラル含有石けんとして麦飯石やウコンを添加した石けん（特許文献１）、よもぎ抽出液、魚由来のコラーゲンと塩化マグネシウム等海洋ミネラルを加えた薬用石けん（特許文献２）、石けん基材にハーブ粉末を添加したハーブ石けん（特許文献３）、化粧石けん基材に木酢液あるいは竹酢液を加えた石けん（特許文献４）、化粧石けん基材に酢を加えた石けん（特許文献５）、クマザサ抽出成分を含有する化粧石けん（特許文献６）等が提案されている。
For example, soap with added barley stone or turmeric as a mineral-containing soap for bathing and facial cleansing (Patent Document 1), wormwood extract, medicinal soap with added marine minerals such as fish-derived collagen and magnesium chloride (Patent Document) 2), soap with herb powder added to soap base (Patent Literature 3), soap with wood vinegar or bamboo vinegar added to cosmetic soap base (Patent Literature 4), vinegar added to cosmetic soap base Soap (Patent Document 5), cosmetic soap containing a Kumazasa extract component (Patent Document 6), and the like have been proposed.
藍は古くから染料として利用されてきているが、藍の持つ不思議な力は万葉の昔から知られ、生活に生かされてきている。武士は鎧の下に藍染めの肌着を着て、切り傷や虫さされから守ったと言われている。藍染めの着物をタンスに入れて置くと、防虫効果があると言われている。ふぐ中毒、食あたり、熱冷ましなどの民間薬として利用されていたと言う。
藍は肌に優しい天然染料としてその良さが見直され、注目されるようになり、染毛剤としての利用が提案（特許文献６、７、８）されている。この他、藍の中には抗菌性物質が存在する溶媒抽出が行われている（特許文献９、１０、１１）。皮膚の炎症を止める機能があることから生理パッドに利用する特許などが提案されている（特許１２）。特許等を調べたが、藍成分の石けんへの応用は提案されていない。
藍の機能に着目し、石けんへの添加を試み、石けんの製造を鋭意研究してきたところである。
藍の色は水に溶けないために、発酵させて可溶化して取り出されており、ハーブのように乾燥粉末化して固化・成型時に添加しても機能発現は期待できない。葉藍成分による機能発現を期待するためには可溶化し、添加する必要があるが、ジクロロメタンやエーテルなどの有機溶媒抽出した場合、有機溶媒の除去などの課題が残る。
Indigo has been reviewed as a natural dye that is gentle on the skin, has attracted attention, and has been proposed for use as a hair dye (Patent Documents 6, 7, and 8). In addition, solvent extraction in which an antibacterial substance exists in indigo is performed (Patent Documents 9, 10, and 11). Since it has a function to stop inflammation of the skin, a patent used for a physiological pad has been proposed (Patent 12). Although patents were examined, no application of indigo ingredients to soap has been proposed.
Focusing on the function of indigo, we have tried to add it to the soap and have been studying the manufacture of soap.
Since the color of indigo is not soluble in water, it has been fermented and solubilized and extracted, and even if it is dried and powdered like an herb and added during solidification / molding, its function cannot be expected. It is necessary to solubilize and add in order to expect functional expression due to the leaf indigo component. However, when organic solvents such as dichloromethane and ether are extracted, problems such as removal of organic solvents remain.

The present invention relates to the production of indigo soap utilizing the functions of indigo. In the present invention, fragrance is added to vegetable oils such as olive oil and palm oil, and the ingredients extracted from leaf indigo and water-soluble ingredients extracted from indigo seeds are used to make soap, producing not only solid soap but also shampoos etc. To do.
In order to extract the indigo color, the leaf indigo is immersed in water and fermented, the remaining leaves are filtered and slaked lime is added with stirring. When bubbles no longer appear, leave it to stand, and when it settles, discard the supernatant and take out the precipitated indigo, and use it as a slurry or as a dry powder. This precipitated indigo is used in the soap manufacturing process.
In addition, the dried leaf indigo is put in the soap plant oil and heated for a predetermined time to extract the oily component in the leaf indigo. After cooling, all the leaves are filtered and removed. Thus, soap is manufactured using indigo extract oil.
本発明の沈殿藍の製造は、通常法で行った。すなわち、生葉藍を水に漬け込み、４８〜７２時間放置して発酵させた後、藍の葉を濾す。藍が溶出した水溶液に石灰水溶液を添加し、撹拌する。泡が出なくなると静置する。上澄み液を捨て、スラリー状の沈殿藍を取り出す。水に沈殿藍を溶解した後、水酸化ナトリウムを溶かして所定濃度（10~20%）の沈殿藍入りの水酸化ナトリウム水溶液を調整する。
オリーブオイル、パームオイル、大豆油などの植物油あるいはこの混合油を加熱して４０℃程度に保ちながら等温の藍入り水酸化ナトリウム水溶液を撹拌下添加して、ケン化させる。粘凋溶液を型枠に入れ、保温箱で覆い所定時間放置して固化させて、石けんを製造するものである。
Production of the precipitated indigo of the present invention was carried out by a usual method. That is, the green leaves are soaked in water and allowed to stand for 48 to 72 hours for fermentation, and then the green leaves are filtered. Add the lime aqueous solution to the aqueous solution from which the indigo has eluted and stir. Let stand when no more foam. Discard the supernatant and take out the slurry indigo blue. After dissolving precipitated indigo in water, sodium hydroxide is dissolved to prepare a sodium hydroxide aqueous solution containing precipitated indigo of a predetermined concentration (10 to 20%).
A vegetable oil such as olive oil, palm oil, soybean oil, or a mixed oil thereof is heated and kept at about 40 ° C., and an isothermal indigo sodium hydroxide aqueous solution is added with stirring to saponify. A viscous solution is placed in a mold, covered with a heat-retaining box, and allowed to solidify for a predetermined time to produce soap.
乾燥葉藍の油抽出成分を用いる藍入り石けんの製造方法の好ましい態様は次の通りである。乾燥葉藍を原料の植物油に添加して所定温度に加熱して、油溶性分を抽出する。この植物油から葉藍を濾別する。藍の油溶性成分を含有する植物油と等温の水酸化ナトリウム水溶液をかき混ぜながら混合してケン化する。上記の方法と同様に型枠に移して保温下に放置して固化する。 A preferred embodiment of the method for producing indigo soap using the dried leaf indigo oil extract component is as follows. Dried leaf indigo is added to the raw vegetable oil and heated to a predetermined temperature to extract the oil-soluble component. Filter the leaf indigo from this vegetable oil. Saponification is carried out by mixing vegetable oil containing indigo oil-soluble components and isothermal sodium hydroxide solution while stirring. In the same manner as described above, it is transferred to a mold and allowed to stand under heat retention to solidify.
藍種子の水抽出成分を用いる石けんの製造方法の好ましい態様は次の通りである。藍の種子を水に入れ、所定時間煮沸して、種子中の水溶性成分を溶解させる。この水溶液に水酸化トリウムを溶解して、所定温度で植物油とかき混ぜながら混合して、ケン化・固化させて石けんを製造することもできる。この場合の藍入り石けんは黄色あるいは白色である。 A preferred embodiment of the method for producing soap using the water extraction component of indigo seed is as follows. Indigo seeds are put in water and boiled for a predetermined time to dissolve water-soluble components in the seeds. Thorium hydroxide is dissolved in this aqueous solution, mixed with vegetable oil at a predetermined temperature and mixed, and saponified and solidified to produce soap. The indigo soap in this case is yellow or white.
藍入り石けん製造の上記とは別の態様、或いは全体が藍入りであり、藍特有の藍色の部分が藍染めをイメージした模様を構成する藍入り石けんの製造方法は、沈殿藍、油溶性成分含有植物油、種子の水溶性成分を含有する水溶液を組み合わせて藍入り石けんを製造するものである。種子から水溶性成分を抽出して水溶液と沈殿藍を混合した後、植物油と混合して石けんを作る場合、色の変化は白色系統より固化・熟成期間に紫色系統の石けんになる。
なお、種子中の水溶性成分を含有する水溶液と沈殿藍を利用して石けんを製造する場合、種子水溶性成分を含有する水溶液に水酸化ナトリウムを溶解し、植物油と混合してケン化させ、型枠に入れる直前の粘凋溶液に沈殿藍を混合して固化すると青色系統の石けんが製造できる。
A method of manufacturing indigo soap that is different from the above in the manufacture of indigo soap, or that is entirely indigo, and that has an indigo-colored indigo-colored pattern in the pattern of indigo dyeing. Indigo soap is produced by combining an ingredient-containing vegetable oil and an aqueous solution containing a water-soluble component of seeds. When water-soluble components are extracted from seeds and mixed with an aqueous solution and precipitated indigo blue, and then mixed with vegetable oil to make soap, the color change becomes a soap of purple color in the solidification / ripening period rather than white.
In addition, when producing soap using an aqueous solution containing water-soluble components in seeds and precipitated indigo, sodium hydroxide is dissolved in an aqueous solution containing seed water-soluble components, mixed with vegetable oil and saponified, Blue soap can be produced by mixing and solidifying the precipitating indigo solution just before putting into the mold.
本発明の石けんは３つの藍抽出物を単独にあるいは複数あるいはすべてを混合して製造することにより藍色等の青色系統、白色系統、黄色系統、紫色系統の色彩を表現することや各色の濃淡を調節し、また、デザイン構成の組み合わせにより幾何学的な模様を構成する藍染をイメージ出来る色彩的にも美しい石けんを製造することが出来る。

４０７ｇのオリーブ油と１２０ｇのココナッツ油と６３ｇのパーム油と４４ｇのシアバターの混合植物油を所定温度（４０℃）に加温し、同温度に加温した藍入りの水酸化ナトリウム水溶液をかき混ぜながら添加する。さらに粘凋になるまでかき混ぜながらケン化させる。つぎに４５ｇの阿波藍の沈殿藍を添加し、さらにかき混ぜ混合させ成型用の型枠に流し込み、保温箱に所定時間（２４時間）静置する。
得られた石けんは藍色で、泡立ち、水切れが良く、肌になめらかで、刺激がなく、使用後の肌はしっとりし、保湿性がよく、タオルなどにも藍が残らなかった。
16 g of indigo seeds are put into 300 ml of purified water, boiled for 10 minutes, and then seeds are separated. In this aqueous solution, 86 g of sodium hydroxide is dissolved to form a sodium hydroxide aqueous solution containing indigo component having a concentration of 150 g / L.
A mixed vegetable oil of 407 g olive oil, 120 g coconut oil, 63 g palm oil, and 44 g shea butter is heated to a predetermined temperature (40 ° C.) and added while stirring the indigo sodium hydroxide aqueous solution heated to the same temperature. To do. Saponify with stirring until more viscous. Next, 45 g of Awa indigo indigo blue is added, and the mixture is further agitated and mixed, poured into a mold for molding, and left in a heat insulating box for a predetermined time (24 hours).
The resulting soap was indigo-colored, foamed, drained well, smooth on the skin, non-irritating, moisturized and moisturized, and no indigo remained on towels.
実施例１で調整した石けんについて測色色差計EZ200を用いて色を測定した。測定したＬ、ａ、ｂ（Ｌが明るさ、ａは赤→緑、ｂは黄→青）を表１（石けんの色測定結果）に示す。藍の入ってない石けんを標準に藍入り石けんの色の差をΔＬ、Δａ，Δｂで示した。比較例として市販の青色化粧石けんと比較した。Ｌの数字が大きいものは明るく、小さいものほど暗い色で、ａ赤から緑で＋が赤、−は緑、ｂの＋は黄色、−は青を表している。藍入りの石けんは青色に着色しており、市販の青色石けんと同等の青に着色しており、明るい石けんであることが分かった。
次いで、この石けんを使用による着色残留性、すなわち、タオル等への色のこりを上記の装置を使用して測定した。
これらの石けんを白色のタオルにこすりつけて洗濯し、良く水洗いした後乾燥した。これを５回繰り返した後の色を未使用のタオルと比較した。その結果を表２（石けん５回使用後のタオル色）に示す。タオルの色はほぼ未処理のものと同じであり、タオルには藍色が着色しないことが分かった。
The color of the soap prepared in Example 1 was measured using a colorimetric color difference meter EZ200. The measured L, a, and b (L is brightness, a is red → green, and b is yellow → blue) are shown in Table 1 (soap color measurement results). The color difference of soap with indigo is shown as ΔL, Δa, Δb with soap without indigo as standard. As a comparative example, it was compared with a commercially available blue cosmetic soap. Larger L numbers are brighter, and smaller ones are darker colors, a red to green, + is red,-is green, b is +, yellow is-, and-is blue. The indigo soap is colored blue, and it is colored blue equivalent to the commercially available blue soap.
Subsequently, the color persistence due to the use of this soap, that is, the color residue on a towel or the like was measured using the above-mentioned apparatus.
These soaps were rubbed on a white towel, washed, thoroughly washed with water and then dried. The color after repeating this 5 times was compared with an unused towel. The results are shown in Table 2 (towel color after using soap 5 times). The color of the towel was almost the same as the untreated color, and it was found that the towel was not colored indigo.
乾燥した葉藍を所定量（３０ｇ）オリーブ油に入れて、所定時間（２分間）加熱し、冷却した後、葉藍をろ別して取り除く。この葉藍中の油性成分が溶解したオリーブ油は青緑色であった。この油と実施例１において調整した藍種子の水溶性成分を含有する水溶液に水酸化ナトリウムを溶解した水溶液とを所定温度（４０℃）に加温した後、かき混ぜながら混合してケン化する。さらに沈殿藍を混合し、これを成型用の型枠に流し込み、保温箱に所定時間（２４時間）静置して藍色の石けんを得た。泡立ち、洗浄力も通常のオリーブ石けんと同等であり、タオルや肌への着色もなく、使用後の肌の感触は非常に快適で、つるつるでしっとり感のある仕上がりであった。 A predetermined amount (30 g) of dried leaf indigo is placed in olive oil, heated for a specified time (2 minutes), cooled, and then filtered to remove the leaf indigo. The olive oil in which the oily component in the leaf was dissolved was blue-green. This oil and an aqueous solution in which sodium hydroxide is dissolved in an aqueous solution containing the water-soluble component of indigo seed prepared in Example 1 are heated to a predetermined temperature (40 ° C.) and then mixed and saponified while stirring. Further, the precipitated indigo was mixed, poured into a mold for molding, and left in a heat insulating box for a predetermined time (24 hours) to obtain indigo soap. Foaming and detergency were the same as ordinary olive soap, there was no coloring on towels and skin, the skin feel after use was very comfortable, and it was smooth and moist.
