Description

【0001】
【発明の属する技術分野】
本発明は、抗菌性にすぐれかつ安全な化粧品および医薬部外品に関するものである。
【0002】
【従来の技術】
化粧品や医薬部外品に抗菌剤を添加する目的には、化粧品や医薬部外品自体の変敗の防止を図る目的と、適用対象となる皮膚面を消毒殺菌して身体の清潔を維持する目的との2つがある。
【0003】
化粧品や医薬部外品用に許容されている抗菌剤の例は、安息香酸またはその塩、パラオキシ安息香酸エステル、サリチル酸またはその塩、ソルビン酸またはその塩、デヒドロ酢酸またはその塩、塩化ベンザルコニウム、オルトフェニルフェノール、グルコン酸クロルヘキシジン、イソプロピルメチルフェノールなどである。
【0004】
合成抗菌剤に代えて天然由来の抗菌剤を添加することも試みられているが、その抗菌性は必ずしも充分でない。
【0005】
特開平6−227931号公報には、シソ、タケ、ショウキョウ、ヨモギおよびニンニクよりなる群から選ばれた植物の乾留物からなる抗菌性成分につき開示がある。この抗菌性成分の用途は主として食品添加用であるが、用途の一つとして化粧品にも適用できる旨の一言の記載がある。
【0006】
タケの減圧乾留物に関するものではないが、特開平7−187990号公報には、竹類の幹または枝の抽出物を主成分とする化粧料が示されている。抽出物とは水抽出物であり、その添加目的は皮脂欠乏症、炎症性皮膚炎等の疾患の治療にある。特開平3−93710号公報には竹等の抽出エキスを有効成分とする皮膚または頭髪用外用剤または化粧料、特開平4−18012号公報には竹類のエキスを有効成分として含有する養毛剤、特開平3−251518号公報には竹から抽出されたフケ菌発育阻害成分を含有する皮膚・頭皮・頭髪剤、特開平5−306232号公報には竹類植物体の粉粒物またはそのエキスを必須成分としてなる外用脱臭除菌剤が示されている。
【0007】
【発明が解決しようとする課題】
化粧品や医薬部外品用に許容されている合成抗菌剤は、安全性の点から、添加量や使い方(すぐに洗い流すかどうか)に種々の制限がある。また合成抗菌剤の多くは、界面活性剤が存在する系においては本来の抗菌力が奏されないことが多い。できれば合成でない抗菌剤を用いることが望ましい。
【0008】
そこで、先にも述べたように合成抗菌剤に代えて天然由来の抗菌剤を添加することも試みられているが、天然由来の抗菌剤は合成抗菌剤に比すれば一般に抗菌力がかなり不足するという問題点がある上、天然由来の抗菌剤にあっても界面活性剤が存在する系においては本来の抗菌力が奏されないことが多い。そこで天然由来の抗菌剤の添加量を多くして抗菌力を高めることが考えられるが、添加量を多くしても一定限界以上には抗菌力は上がらない上、においや着色の原因となって化粧品や医薬部外品としての価値が低下することもある。またいくら天然由来の抗菌剤であるとは言え、極端に添加量を増やすことはできるだけ避けたい。
【0009】
本発明は、このような背景下において、抗菌性にすぐれ、界面活性剤が存在する系においても抗菌性が発揮され、しかも毒性を有せずかつ皮膚刺激性も小さいので安全性が高い化粧品および医薬部外品を提供することを目的とするものである。
【0010】
【課題を解決するための手段】
本発明の化粧品および医薬部外品は、タケを減圧条件下に乾留したときに留出するタケ減圧乾留物(A) と食塩(B) との双方を含有することを特徴とするものである。
【0011】
【発明の実施の形態】
以下本発明を詳細に説明する。
【0012】
タケ減圧乾留物(A) としては、タケ(殊に孟宗竹)を、必要に応じて粉砕、乾燥した後、減圧条件下に乾留したときに留出する減圧乾留物が用いられる。
【0013】
減圧条件としては、100mmHg以下、好ましくは10〜60mmHg、殊に15〜45mmHgの条件が好適に採用される。減圧乾留時の初留分は適宜カットしてもよく、また減圧乾留物をさらに精製処理してもよい。常圧下の乾留または減圧度が小さい条件下の乾留で得た留出物は抗菌能力が不足し、本発明の目的を充分には達成しえない。
【0014】
上記減圧乾留時の乾留物の留出温度は減圧度に依存するが(減圧度が大きいときは低く、減圧度が小さいときは高い)、たとえば20mmHgの減圧乾留の場合で300℃前後となる。
【0015】
上記の操作により得られた減圧乾留物(A) は通常は粘稠な液体であるので、取り扱いの便宜上、一旦留出物を水、エタノール、プロピレングリコールなどで受け、ついでそれを水やエタノールで濃度調節するようにするのが適当である。
【0016】
なお、タケの水や溶剤による抽出物は、上記のタケ減圧乾留物(A) に比し抗菌力が著しく小さいので、本発明の目的には適していない。
【0017】
本発明の化粧品および医薬部外品は、上記のタケ減圧乾留物(A) と食塩(B) とを含有するものである。タケ減圧乾留物(A) と食塩(B) のどちらか一方を欠くときは、抗菌性の点で満足のいく結果が得られない。
【0018】
化粧品や医薬部外品に占めるタケ減圧乾留物(A) の添加量は、減圧乾留時の留出物基準で、0.0001〜10重量%、好ましくは0.0005〜5重量%、さらに好ましくは 0.001〜2重量%が適当であり、化粧品や医薬部外品に占める食塩(B) の添加量は、0.01〜20重量%、好ましくは0.05〜15重量%、さらに好ましくは 0.1〜10重量%が適当である。
【0019】
ここで化粧品および医薬部外品としては、次に例示するような化粧品、薬用化粧品、医薬部外品があげられる。なおこれらは一般には人体を対象とするものであるが、本発明においては人のみならずペット等の動物を対象とする場合も含むものとする。
【0020】
化粧品としては、頭髪用化粧品類(髪油、染毛料、スキ油、セットローション、チック、びん付油、ヘアクリーム、ヘアトニック、ヘアリキッド、ヘアスプレー、ポマード等)、洗髪用化粧品類(髪洗い粉、シャンプー等)、化粧水類(アフターシェービングローション、一般化粧水、オーデコロン、シェービングローション、ハンドローション、日焼けローション、日焼け止めローション等)、クリーム乳液類(アフターシェービングクリーム、クレンジングクリーム、コールドクリーム、シェービングクリーム、乳液、バニシングクリーム、ハンドクリーム、日焼けクリーム、日焼け止めクリーム等)、パック類(パック用化粧料等)、ファンデーション類(クリーム状ファンデーション、液状ファンデーション、固形ファンデーション等)、白粉打粉類(クリームおしろい、固形おしろい、粉おしろい、タルカムパウダー、練おしろい、ベビーパウダー、ホディパウダー、水おしろい等)、口紅類(口紅、リップクリーム等)、眉目頬化粧品類(アイクリーム、アイシャドー、アイライナー、頬紅、マスカラ、眉墨等)、爪化粧品類(美爪エネメル、美爪エナメル除去液等)、香水類(一般香水、練香水、粉末香水等)、浴用化粧品類(バスオイル、バスソルト等)、化粧油類(化粧用油、ベビーオイル等)、洗顔料類(洗顔クリーム、肌洗い粉、洗顔フォーム等)、石けん類(化粧石けん等)、歯みがき類などがあげられる。
【0021】
薬用化粧品としては、シャンプー、リンス、化粧水、クリーム、乳液、ハンドクリーム、化粧用油、ひげそり用剤、日やけ止め剤、パック、薬用石けんなどのうち薬用化粧品に属するものがあげられる。
【0022】
医薬部外品としては、口中清涼剤、腋臭防止剤、てんか粉類、育毛剤(養毛剤)、除毛剤、染毛剤(脱色剤、脱染剤)、浴用剤、薬用化粧品(薬用石けんを含む)、薬用歯磨類、殺虫剤(忌避剤)、殺鼠剤、パーマネント・ウェーブ用剤、衛生綿類などがあげられる。
【0023】
〈作用〉
タケ減圧乾留物(A) を単独で添加した化粧品や医薬部外品においても若干の抗菌力が奏されるが、その抗菌力は充分ではない。また食塩(B) を単独で添加した化粧品や医薬部外品においても抗菌力が奏されるが、濃度が低い状態では抗菌力が充分とは言えない。しかるに、化粧品や医薬部外品にタケ減圧乾留物(A) と食塩(B) との双方を含有させた場合には、双方の添加量が比較的少ない場合でも抗菌性の点で相乗効果が得られる。
【0024】
タケ減圧乾留物(A) は天然物由来のものであり、また食用に供してもよいほどのものであるので、安全性が高いものである。
【0025】
このように本発明の化粧品および医薬部外品はすぐれた抗菌力を有し、しかも界面活性剤が存在する系においてもすぐれた抗菌性が発揮される。そして本発明の化粧品および医薬部外品は、肌にやさしく、皮膚刺激性を事実上有しない。
【0026】

〈解析〉
Echerichia coli について見ると、タケ減圧乾留物のみを含むNo.2の試料(比較例1)においては、1時間後も24時間後も菌数に大きな減少は認められなかった。食塩のみを含むNo.3の試料(比較例2)においては、24時間後には菌数が顕著に減少したが、1時間後ではまだ菌数の減少は充分ではなかった。これに対し、タケ減圧乾留物と食塩との双方を含むNo.1(実施例1)の試料にあっては、1時間後でも生菌数は顕著に減少し、両者の併用により相乗効果が奏されることがわかった。なお、別途測定したEcherichia coli に対するタケ減圧乾留物のMIC(最小発育阻止濃度)は1.25%であった。
【0034】
Bacillus subtilis について見ると、タケ減圧乾留物のみを含むNo.2の試料(比較例1)においては、菌数の減少に限界があった。食塩のみを含むNo.3の試料(比較例2)においても、菌数の減少に限界があった。これに対し、タケ減圧乾留物と食塩との双方を含むNo.1(実施例1)の試料にあっては、そのような限界を破って生菌数が顕著に減少し、両者の併用により相乗効果が奏されることがわかった。なお、別途測定したBacillus subtilis に対するタケ減圧乾留物のMIC(最小発育阻止濃度)は2.50%であった。
【0035】
Staphyrococcus aureus について見ると、タケ減圧乾留物のみを含むNo.2の試料(比較例1)においては、菌数の減少に限界があった。食塩のみを含むNo.3の試料(比較例2)においては、24時間後には菌数が顕著に減少したが、1時間後ではまだ菌数の減少は必ずしも充分ではなかった。これに対し、タケ減圧乾留物と食塩との双方を含むNo.1(実施例1)の試料にあっては、1時間後でも生菌数はかなり減少し、24時間後には菌数が顕著に減少し、両者の併用により相乗効果が奏されることがわかった。なお、別途測定したStaphyrococcus aureus に対するタケ減圧乾留物のMIC(最小発育阻止濃度)は5.00%であった。
【0036】
全体的な傾向を見ると、タケ減圧乾留物と食塩との双方を含有させると、それぞれの単品では到達しえない相乗効果が得られることがわかる。

【発明の効果】
作用の項でも述べたように、本発明の化粧品および医薬部外品は、抗菌性にすぐれ、界面活性剤が存在する系においても抗菌性が発揮され、しかも毒性や皮膚刺激性が認められず、安全性が高い。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to cosmetics and quasi-drugs having excellent antibacterial properties and safety.
[0002]
[Prior art]
The purpose of adding antibacterial agents to cosmetics and quasi-drugs is to prevent deterioration of cosmetics and quasi-drugs themselves, and to maintain the cleanliness of the body by disinfection and sterilization There are two purposes.
[0003]
Examples of antibacterial agents that are acceptable for cosmetics and quasi drugs are benzoic acid or its salts, paraoxybenzoic acid esters, salicylic acid or its salts, sorbic acid or its salts, dehydroacetic acid or its salts, benzalkonium chloride Orthophenylphenol, chlorhexidine gluconate, isopropylmethylphenol, and the like.
[0004]
Although attempts have been made to add natural antibacterial agents instead of synthetic antibacterial agents, the antibacterial properties are not always sufficient.
[0005]
Japanese Patent Application Laid-Open No. 6-227931 discloses an antibacterial component composed of a dry-distilled product of a plant selected from the group consisting of perilla, bamboo, ginger, mugwort and garlic. The use of the antibacterial component is mainly for food addition, but there is a statement that it can be applied to cosmetics as one of the uses.
[0006]
Although not related to the reduced-pressure dry-distilled product of bamboo, JP-A-7-187990 discloses a cosmetic mainly composed of an extract of bamboo trunks or branches. The extract is a water extract, and its purpose is to treat diseases such as sebum deficiency and inflammatory dermatitis. JP-A-3-93710 discloses an external preparation or cosmetic for skin or hair containing an extract such as bamboo as an active ingredient, and JP-A-4-18012 discloses a hair nourishing agent containing an extract of bamboo as an active ingredient, JP-A-3-251518 discloses a skin / scalp / hair agent containing an dandruff fungus growth inhibitory component extracted from bamboo, and JP-A-5-306232 discloses a bamboo plant powder or extract thereof. An external deodorizing and disinfecting agent as an essential component is shown.
[0007]
[Problems to be solved by the invention]
Synthetic antibacterial agents allowed for cosmetics and quasi-drugs have various restrictions on the amount of addition and usage (whether they are washed out immediately) from the viewpoint of safety. Many of the synthetic antibacterial agents often do not exhibit their original antibacterial activity in a system where a surfactant is present. It is desirable to use non-synthetic antibacterial agents if possible.
[0008]
Therefore, as mentioned earlier, attempts have been made to add natural antibacterial agents in place of synthetic antibacterial agents, but natural antibacterial agents are generally insufficient in antibacterial activity compared to synthetic antibacterial agents. In addition, even in the case of naturally occurring antibacterial agents, the original antibacterial activity is often not achieved in a system in which a surfactant is present. Therefore, it is conceivable to increase the antibacterial activity by increasing the amount of naturally-occurring antibacterial agents. However, even if the addition amount is increased, the antibacterial activity does not increase beyond a certain limit, and it causes odors and coloring. The value as a cosmetic or quasi-drug may be reduced. Although it is a natural-derived antibacterial agent, it is desirable to avoid increasing the amount of addition as much as possible.
[0009]
Under such a background, the present invention has excellent antibacterial properties, exhibits antibacterial properties even in a system in which a surfactant is present, and has high safety because it has no toxicity and low skin irritation. The purpose is to provide a quasi-drug.
[0010]
[Means for Solving the Problems]
The cosmetics and quasi-drugs of the present invention are characterized in that they contain both a bamboo vacuum-distilled product (A) and a salt (B) that are distilled when the bamboo is carbonized under reduced-pressure conditions. .
[0011]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described in detail below.
[0012]
As the bamboo reduced-pressure distillate (A), a reduced-pressure distillate obtained by distilling bamboo (particularly, Misotake), if necessary, is pulverized and dried, and then distilled under reduced pressure.
[0013]
As the depressurizing condition, a condition of 100 mmHg or less, preferably 10 to 60 mmHg, particularly 15 to 45 mmHg is suitably employed. The initial fraction during vacuum dry distillation may be appropriately cut, and the vacuum dry distillation product may be further purified. The distillate obtained by dry distillation under normal pressure or under low pressure conditions has insufficient antibacterial ability and cannot sufficiently achieve the object of the present invention.
[0014]
The distillation temperature of the dry distillation product during the above-mentioned vacuum dry distillation depends on the degree of vacuum (low when the degree of vacuum is high and high when the degree of vacuum is low), but is about 300 ° C. in the case of 20 mmHg vacuum distillation.
[0015]
The vacuum dry-distilled product (A) obtained by the above operation is usually a viscous liquid. For convenience of handling, the distillate is once received with water, ethanol, propylene glycol, etc., and then it is washed with water or ethanol. It is appropriate to adjust the concentration.
[0016]
Note that the extract of bamboo water or solvent is not suitable for the purpose of the present invention because it has a significantly lower antibacterial activity than the above-mentioned bamboo vacuum distilled product (A).
[0017]
The cosmetics and quasi-drugs of the present invention contain the above-described bamboo vacuum distilled product (A) and sodium chloride (B). Satisfactory results cannot be obtained in terms of antibacterial properties when either one of the bamboo vacuum distilled products (A) or salt (B) is lacking.
[0018]
The amount of bamboo vacuum dried product (A) added to cosmetics and quasi-drugs is 0.0001 to 10% by weight, preferably 0.0005 to 5% by weight, more preferably 0.001 to 2%, based on the distillate during vacuum dry distillation. The amount of sodium chloride (B) in cosmetics and quasi-drugs is 0.01 to 20% by weight, preferably 0.05 to 15% by weight, more preferably 0.1 to 10% by weight. .
[0019]
Here, examples of cosmetics and quasi drugs include cosmetics, medicated cosmetics, and quasi drugs as exemplified below. In general, these are intended for the human body, but the present invention includes not only humans but also animals such as pets.
[0020]
Cosmetics include hair cosmetics (hair oil, hair dye, skin oil, set lotion, tics, bottled oil, hair cream, hair tonic, hair liquid, hair spray, pomade, etc.), hair washing cosmetics (hair wash powder) , Shampoo, etc.), lotion (after shaving lotion, general lotion, cologne, shaving lotion, hand lotion, sun tan lotion, sunscreen lotion, etc.), cream milk (after shaving cream, cleansing cream, cold cream, shaving cream) , Emulsions, vanishing creams, hand creams, sun creams, sun creams, etc.), packs (pack cosmetics, etc.), foundations (creamy foundation, liquid foundation, solid foundation) ), White flour powder (cream cream, solid powder, powder powder, talcum powder, kneading powder, baby powder, body powder, water powder, etc.), lipsticks (lipstick, lip balm, etc.), eyebrow cheek cosmetics (eye cream, Eye shadow, eyeliner, blusher, mascara, eyebrow, etc.) nail cosmetics (beauty nail enamel, beauty nail enamel remover, etc.), perfume (general perfume, perfume, powder perfume, etc.), bath cosmetics (bath oil) , Bath salts, etc.), cosmetic oils (cosmetic oil, baby oil, etc.), facial cleansers (facial cleansing cream, skin wash powder, facial foam, etc.), soaps (cosmetic soap, etc.), dentifrices and the like.
[0021]
Examples of medicinal cosmetics include shampoos, rinses, lotions, creams, emulsions, hand creams, cosmetic oils, shaving agents, sunscreen agents, packs, medicated soaps, and the like that belong to medicinal cosmetics.
[0022]
As quasi-drugs, mouth refreshing agents, anti-smelling odors, fry powders, hair growth agents (hair nourishing agents), hair removal agents, hair dyes (decoloring agents, decoloring agents), bath preparations, medicated cosmetics (medicinal soaps) Pharmaceutical toothpastes, insecticides (repellents), rodenticides, permanent wave agents, sanitary cotton and the like.
[0023]
<Action>
Although some antibacterial activity is exhibited in cosmetics and quasi-drugs to which the bamboo vacuum distilled product (A) is added alone, the antibacterial activity is not sufficient. Antibacterial activity is also exhibited in cosmetics and quasi-drugs to which sodium chloride (B) is added alone, but it cannot be said that the antibacterial activity is sufficient at low concentrations. However, when both the bamboo vacuum distilled product (A) and the salt (B) are contained in cosmetics and quasi-drugs, there is a synergistic effect in terms of antibacterial properties even when the addition amount of both is relatively small. can get.
[0024]
Bamboo vacuum-distilled product (A) is derived from a natural product and is so safe that it can be used for food.
[0025]
Thus, the cosmetics and quasi-drugs of the present invention have excellent antibacterial activity, and also exhibit excellent antibacterial properties even in a system where a surfactant is present. And the cosmetics and quasi drugs of the present invention are gentle to the skin and have virtually no skin irritation.
[0026]

The crushed material of bamboo (Moso bamboo) is supplied to a vacuum distillation unit, and vacuum-distilled under conditions of a pressure of about 20 mmHg and a temperature of about 300 ° C., and the distillate (containing water) is received with water and further with water. The concentration was adjusted to obtain an aqueous solution having a distillate concentration of about 20%. The non-volatile concentration of this aqueous solution was about 3%.
[0028]
<sample>
The following three types were prepared as test samples.
-No.1: An aqueous solution obtained by adding 1.25 parts of an aqueous solution having a distillate concentration of about 20% and 3.75 parts of sodium chloride to sterilized water to make 100 parts.
-No.2: An aqueous solution obtained by adding 1.25 parts of an aqueous solution having a distillate concentration of about 20% to sterilized water to 100 parts.
-No.3: An aqueous solution obtained by adding 3.75 parts of salt to sterilized water to make 100 parts.
[0029]
<Used bacterial species>
The following three types of bacteria were prepared.
・ Echerichia coli IFO 3806
・ Bacillus subtilis IFO 3009
・ Staphyrococcus aureus IFO 13276
[0030]
<Test operation>
In a sterilized plastic petri dish having a diameter of 90 mm, 100 μl of a pre-cultured bacterial solution diluted 1000 times was added, and 20 g of the above aqueous solution was further added. The liquid after contact for 1 hour and 24 hours was taken, diluted 10 times, and smeared on an agar plate medium having the following composition, and the viable cell count was measured. The initial bacterial count is about 100 to 500 cells / ml, and the medium composition is glucose 1.00 part, peptone 0.50 part, powdered yeast extract 0.30 part, KH 2 PO 4 0.03 part, K 2 HPO 4 0.03 part, MgSO 4 0.01 part. , 1.50 parts agar, 96.93 parts purified water, pH 7.0.
[0031]
<Test results>
The test results are shown in Table 1 below. In the table, “<1” means 1 or less, and “<10” means 10 or less. No. 1 is an example, No. 2 and No. 3 are comparative examples, and No. 4 is a control.

<analysis>
As for Echerichia coli, no significant decrease was observed in the number of bacteria in No. 2 sample (Comparative Example 1) containing only bamboo vacuum-distilled product after 1 hour and 24 hours. In the sample No. 3 containing only sodium chloride (Comparative Example 2), the number of bacteria was significantly reduced after 24 hours, but the number of bacteria was still not sufficiently reduced after 1 hour. On the other hand, in the sample No. 1 (Example 1) containing both the bamboo vacuum-distilled product and the salt, the viable cell count is remarkably reduced even after 1 hour, and the combined use of both results in a synergistic effect. I understood that it was played. In addition, the MIC (minimum growth inhibitory concentration) of the bamboo vacuum dried product with respect to Echerichia coli measured separately was 1.25%.
[0034]
As for Bacillus subtilis, No. 2 sample (Comparative Example 1) containing only bamboo vacuum-distilled product had a limit in reducing the number of bacteria. Even in the sample No. 3 containing only salt (Comparative Example 2), there was a limit to the reduction in the number of bacteria. On the other hand, in the sample No.1 (Example 1) containing both the bamboo vacuum-distilled product and the salt, the number of viable bacteria was significantly reduced by breaking such a limit. A synergistic effect was found. In addition, the MIC (minimum growth inhibitory concentration) of the bamboo vacuum distilled product against Bacillus subtilis separately measured was 2.50%.
[0035]
As for Staphyrococcus aureus, there was a limit to the decrease in the number of bacteria in the No. 2 sample (Comparative Example 1) containing only the bamboo vacuum distilled product. In the sample No. 3 containing only sodium chloride (Comparative Example 2), the number of bacteria was significantly reduced after 24 hours, but the number of bacteria was still not sufficiently reduced after 1 hour. On the other hand, in the sample No. 1 (Example 1) containing both the bamboo vacuum-distilled product and the salt, the number of viable bacteria decreased considerably even after 1 hour, and the number of bacteria became remarkable after 24 hours. It was found that a synergistic effect was achieved by the combined use of both. In addition, the MIC (minimum growth inhibitory concentration) of the bamboo vacuum distilled product against Staphyrococcus aureus separately measured was 5.00%.
[0036]
Looking at the overall trend, it can be seen that when both the bamboo vacuum-distilled product and the salt are contained, a synergistic effect that cannot be achieved by each single product can be obtained.
