Description

【0001】
【発明の属する技術分野】
本発明は、抗菌材料およびその製造方法に関し、詳細には、紙おむつ、包帯等の衛生用品に適した抗菌材料に関する。
【0002】
【従来の技術】
乳幼児、お年寄りが使用する紙おむつや、包帯等の人体に接触する衛生用品は、接触した皮膚より排出された汗やその他体液等が衛生用品に一部移動し、その衛生用品の中で細菌が繁殖することがある。この細菌の繁殖は、皮膚かぶれ等の原因となることが知られている。最近は、アトピー性等の皮膚炎になりやすい子供も増加しており、皮膚かぶれは重大な問題となっている。
【0003】また、排出された汗や体液を含む排泄物および前記排泄物に繁殖した細菌などが発する臭気も重大な問題となっている。
【0004】このような臭気の除去に関しては、例えば、活性炭(特開昭57−142256号公報)、ゼオライト(特開昭56−3054号公報)、グリチルリチン(特開平9−108261号公報)等、香料や吸着剤等の添加で軽減する方法が知られている。しかし、臭気の除去の継続性・実効性という点で、あるいは、皮膚かぶれの防止の点で、依然として問題は残っている。
【0005】クマザサ抽出成分が抗菌作用を有することは知られている。しかしながら、クマザサの抽出成分を直接包帯等に塗布すると効果の持続性が少なく、又、クマザサ抽出成分を通常のカプセルにて保持する方法は、効果を発揮させるためには、カプセルの殻を破壊する必要があった。
【0006】
【発明が解決しようとする課題】
本発明は、皮膚かぶれの防止と臭気の除去とを長時間持続できる衛生もしくは医療用品を提供するための抗菌材料、該抗菌材料を付帯処理した衛生もしくは医療用品および該抗菌材料の製造方法を提供するものである。
【0007】
【課題を解決するための手段】
すなわち、本発明は、多孔質カプセルにクマザサ抽出成分を含有させたことを特徴とする抗菌材料に関する。
【0008】更に本発明は、多孔質カプセルを構成する材料がシリカ微粒子である上記抗菌材料に関する。
【0009】更に本発明は、多孔質カプセルの粒径が0.5〜50μmである上記抗菌材料に関する。
【0010】更に本発明は、担持体に上記抗菌材料を付帯処理してなる衛生もしくは医療用品。
【0011】更に本発明は、界面反応法にて形成した多孔質カプセルを乾燥して中空化させた後真空脱気を行う工程、及び脱気状態となった上記カプセル中空部にクマザサ抽出成分を吸収させカプセル化する工程とからなることを特徴とする抗菌材料の製造方法に関する。
【0012】
【発明の実施の形態】
本発明で使用されるクマザサ抽出成分とは、イネ科クマザサから抽出される「ササ配糖体」を主成分とする成分である。「ササ配糖体」は、キシロース、アラビノース等のペントース(五炭糖)、ガラクトース、グルコース等のヘキソース(六炭糖)を構造単糖とする。クマザサは、古くから薬効のある植物として伝承され、抗菌作用、防腐作用、消臭作用、抗腫瘍作用、細胞賦活作用等の効果があることが知られている。
【0013】クマザサ抽出成分は、クマザサを裁断したのち、水、アルコールなどの抽出溶剤に浸漬して圧搾し、また、抽出装置による濃縮を行い、クマザサ抽出液として得ることができる。クマザサ抽出液は適宜、水等で希釈して使用することができる。
【0014】クマザサ抽出成分は、皮膚かぶれの原因となる菌や、臭気の原因となる菌と臭気化合物を分解する作用があるので、皮膚かぶれ防止と臭気の問題が、持続的、実効的に解決される。
【0015】クマザサ抽出成分は、多糖体を主成分とするため親水性であり、水溶液として取り扱いができる。さらに、特に高湿度の環境でクマザサ抽出成分の抗菌作用等が発現されやすいために、体液を吸収して高湿度の環境となる衛生用品は、他の抗菌作用等を示す天然素材に比べてクマザサ抽出成分の抗菌作用等が活用できる最適用途といえる。
【0016】本発明の抗菌材料は、このクマザサ抽出成分を殻部に多数の細孔を有する多孔質カプセルに充填したものである。多孔質カプセルを構成する殻材料としては、皮膚へ接触しても問題のないシリカ材料等の無機材料が好ましい。
【0017】本発明のクマザサ抽出液を含む多孔質カプセルは、界面反応法にて製造する。界面反応法は、例えば、珪酸ナトリウムの水溶液とHLB3.5〜7.5に調整した揮発性の炭化水素溶剤とを乳化させW/Oのエマルションを形成したのち、硫酸アンモニウムの水溶液にて(w/o)/Wの状態にて界面反応をさせ、反応後、メタノールによる洗浄、精製水による洗浄後、加熱乾燥する。又、上記工程で硫酸アンモニウムに代えて塩化カルシウムを使用すれば珪酸カルシウムを殻とした中空カプセルを形成することができる。
【0018】このようにして得られた中空カプセルは、真空脱気装置にて十分系内を脱気し、しかる後、クマザサ抽出成分を導入し、カプセル中空部にクマザサ抽出成分を注入する。さらに、クマザサ抽出液を含有させたのち、カプセルへの加圧状態を加えることはさらに有効である。
【0019】本発明の抗菌材料が使用される衛生もしくは医療用品は、皮膚に密着して使用するものであり、例えば、紙おむつ、包帯、絆創膏、ナプキン等が挙げられる。抗菌材料を付帯する担持体としては織布、不織布、プラスチックフィルム、紙等がある。
【0020】本発明の抗菌材料を担持体に付帯させるには、抗菌材料を含む液を担持体に塗布、噴霧するか、担持体を抗菌材料を含む液に含浸することにより物理的または化学的に固定する。
【0021】付帯処理するための液は、クマザサ抽出成分を含有する多孔質カプセルをそのまま、あるいはクマザサ抽出成分を含有する多孔質カプセルを適当なバインダーに配合した液である。
【0022】
【実施例】
以下に実施例を示し、本発明を具体的に説明する。
【0023】実施例1
珪酸ナトリウム水溶液とHLB4.8に調整したヘキサンとを浸透させW/Oエマルションを作成した。このエマルションを、硫酸アンモニウム溶液に注入し、30分反応させた。反応後、遠心分離によりカプセルを沈降させてとりだし、メタノール洗浄後、精製水にて洗浄した。減圧濾過にて沈殿物を取り出し、110℃のオーブンにて約12時間加熱乾燥させた。得られたシリカ白色粉末は、粒径が8μmの球状であり、多孔質の中空状であった。このシリカ多孔質中空微粒子カプセルを減圧脱気し、しかる後、クマザサエキス(金井藤吉商店製)25%水溶液を、カプセルに含有させ抗菌材料を作成した。この抗菌材料を、ポリエチレン製の不織布、吸水性ポリマーおよびポリエチレンからなる紙おむつの不織布側に2g/m(固形分)塗布させた後乾燥させ、抗菌処理紙おむつを得た。
【0024】この抗菌処理紙おむつを約2cmの円形に切り取り、試験片としてシャーレに入れた。試験片の不織布側へ、大腸菌(Escherichia coli IFO 3972)の菌数が約300,000個/mlである菌培養液0.1mlを滴下した。シャーレのふたを閉め、35℃、相対湿度90%で19時間保存した。試験片を減菌生理食塩水1.9mlで洗い出し、回収液とした。この回収液を普通寒天培地で35℃、24時間培養して生菌数を測定したところ、菌は検出されなかった。
【0025】比較例1
実施例1において、抗菌処理をしていない紙おむつと同じ製品を用いた以外は、実施例2と同様の操作を行って、生菌数を測定したところ、約90,000,000個/mlであった。
【0026】
【発明の効果】本発明の抗菌材料は、クマザサ抽出成分を多孔質カプセルに充填したものであり抗菌作用が持続する。したがって、本発明の抗菌材料を使用した衛生用品は、菌の増殖による臭気の発生と皮膚かぶれとを防止し、また脱臭効果により臭気を消臭することができる。

Hygiene products that come into contact with the human body, such as disposable diapers and bandages used by babies and the elderly, may cause some of the sweat and other body fluids discharged from the contacted skin to migrate to the hygiene products, and bacteria may form in the hygiene products. May breed. It is known that the propagation of the bacteria causes skin rash and the like. Recently, the number of children who are susceptible to dermatitis such as atopic property has increased, and skin rash has become a serious problem.
[0003] Excretion including sweat and body fluids discharged and odors generated by bacteria propagated in the excretion are also a serious problem.
[0004] Regarding the removal of such odor, for example, activated carbon (Japanese Patent Application Laid-Open No. 57-142256), zeolite (Japanese Patent Application Laid-Open No. 56-3054), glycyrrhizin (Japanese Patent Application Laid-Open No. 9-108261) and the like can be used. There is known a method of reducing the amount by adding a fragrance, an adsorbent, or the like. However, problems remain with regard to the continuity and effectiveness of the removal of odors or the prevention of skin irritation.
It is known that Kumazasa extract has an antibacterial effect. However, when the extract component of Kumazasa is directly applied to a bandage or the like, the effect is less persistent, and the method of holding the Kumazasa extract component in a normal capsule destroys the shell of the capsule in order to exhibit the effect. Needed.
[0006]
[Problems to be solved by the invention]
The present invention provides an antibacterial material for providing a sanitary or medical product capable of preventing skin irritation and removing odor for a long time, a sanitary or medical product with the antibacterial material attached thereto, and a method for producing the antibacterial material. Is what you do.
[0007]
[Means for Solving the Problems]
That is, the present invention relates to an antibacterial material characterized by containing a Kumazasa extract component in a porous capsule.
Further, the present invention relates to the above antibacterial material, wherein the material constituting the porous capsule is silica fine particles.

Absorbing and encapsulating the antimicrobial material.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
The Kumazasa extract component used in the present invention is a component containing “sasa glycoside” extracted from Kumazasa (Poaceae) as a main component. The “sasa glycoside” has pentose (pentose) such as xylose and arabinose, and hexose (hexose) such as galactose and glucose as structural monosaccharides. Kumazasa has long been handed down as a medicinal plant and is known to have antibacterial, antiseptic, deodorant, antitumor, and cell-activating effects.
[0013] The extract of Kumazasa can be obtained as a Kumazasa extract by cutting Kumazasa, immersing it in an extraction solvent such as water or alcohol, squeezing it, and performing concentration by an extraction device. The Kumazasa extract can be appropriately diluted with water or the like before use.
The extract of Kumazasa has the effect of decomposing bacteria that cause skin irritation, and bacteria and odor compounds that cause odor, so that the problem of skin irritation and the problem of odor are continuously and effectively solved. Is done.
The extract of Kumazasa is hydrophilic because it contains a polysaccharide as a main component and can be handled as an aqueous solution. Furthermore, since the antibacterial effect of Kumazasa extract is easily developed especially in a high humidity environment, hygiene products that absorb body fluids and create a high humidity environment are more difficult than other natural materials that exhibit antibacterial activity. It can be said that this is an optimal use where the antibacterial action of the extracted component can be utilized.
The antibacterial material of the present invention is obtained by filling the extract of Kumazasa into a porous capsule having a large number of pores in its shell. As the shell material constituting the porous capsule, an inorganic material such as a silica material which does not cause any problem even when it comes into contact with the skin is preferable.
The porous capsule containing the Kumazasa extract of the present invention is produced by an interfacial reaction method. In the interface reaction method, for example, an aqueous solution of sodium silicate and a volatile hydrocarbon solvent adjusted to HLB 3.5 to 7.5 are emulsified to form a W / O emulsion, and then an aqueous solution of ammonium sulfate (w / o) An interfacial reaction is performed in the state of / W, and after the reaction, washing with methanol, washing with purified water, and then heating and drying. If calcium chloride is used instead of ammonium sulfate in the above step, a hollow capsule having calcium silicate as a shell can be formed.
The inside of the hollow capsule thus obtained is sufficiently degassed by a vacuum deaerator, and thereafter, a Kumazasa extract component is introduced, and the Kumazasa extract component is injected into the hollow portion of the capsule. Further, it is more effective to add a pressurized state to the capsule after containing the Kumazasa extract.
The sanitary or medical supplies to which the antibacterial material of the present invention is applied are used in close contact with the skin, and include, for example, disposable diapers, bandages, adhesive plasters, napkins and the like. Examples of the carrier having the antibacterial material include woven fabric, nonwoven fabric, plastic film, and paper.
In order to attach the antibacterial material of the present invention to a carrier, a solution containing the antibacterial material is applied to the carrier and sprayed, or the carrier is impregnated with a solution containing the antibacterial material by physical or chemical treatment. Fixed to.
The liquid for the supplementary treatment is a liquid in which the porous capsule containing the extract of Kumazasa is used as it is, or the porous capsule containing the extract of Kumazasa is mixed with an appropriate binder.

Embodiment 1
An aqueous solution of sodium silicate and hexane adjusted to HLB 4.8 were permeated to prepare a W / O emulsion. This emulsion was poured into an ammonium sulfate solution and reacted for 30 minutes. After the reaction, the capsule was settled out by centrifugation and taken out. After washing with methanol, the capsule was washed with purified water. The precipitate was taken out by filtration under reduced pressure, and dried by heating in a 110 ° C. oven for about 12 hours. The obtained silica white powder was spherical with a particle size of 8 μm, and was porous and hollow. The silica porous hollow microparticle capsule was degassed under reduced pressure, and thereafter, a 25% aqueous solution of Kumazasa extract (manufactured by Kanai Tokichi Shoten) was contained in the capsule to prepare an antibacterial material. This antibacterial material was applied to a nonwoven fabric side of a disposable diaper made of polyethylene nonwoven fabric, a water-absorbing polymer and polyethylene at a rate of 2 g / m 2 (solid content) and then dried to obtain an antibacterial treated disposable diaper.
This antibacterial treated paper diaper was cut into a circular shape of about 2 cm and placed in a petri dish as a test piece. To the non-woven fabric side of the test piece, 0.1 ml of a bacterial culture containing about 300,000 bacteria / ml of Escherichia coli IFO 3972 was dropped. The petri dish was closed and stored at 35 ° C. and 90% relative humidity for 19 hours. The test piece was washed out with 1.9 ml of sterile physiological saline and used as a recovered solution. This recovered solution was cultured on a normal agar medium at 35 ° C. for 24 hours, and the number of viable bacteria was measured. As a result, no bacteria were detected.
Comparative Example 1
In Example 1, the same operation as in Example 2 was performed except that the same product as the disposable diaper not subjected to the antibacterial treatment was used, and the number of viable bacteria was measured. As a result, about 90,000,000 cells / ml were obtained. there were.
[0026]
The antibacterial material of the present invention is obtained by filling a Kumazasa extract component in a porous capsule, and the antibacterial action is maintained. Therefore, the sanitary article using the antibacterial material of the present invention can prevent the generation of odor due to the growth of bacteria and the skin rash, and can deodorize the odor by the deodorizing effect.
