Description

本発明は、エタノールの速効性と強塩基性のグルコン酸クロロヘキシジンの優れた残留性による持続効果を併せ持ち、かつクリームによる油分補給により手あれを防止でき、既存のアルコール含有消毒剤に比して低濃度エタノールを含有するヒト手指および皮膚の殺菌・消毒可能な医薬組成物に関する。前記医薬組成物は、エタノールを10〜23重量%含有するハンドクリーム剤等の乳化組成物、あるいはエタノールを上限濃度45重量%を含有する乳状液剤でポンプ式またはエアゾール剤として提供される。  The present invention has both a fast-acting effect of ethanol and a long-lasting effect due to the excellent persistence of chlorohexidine gluconate, and it can prevent hand-off by replenishing oil with cream, and has a lower concentration than existing alcohol-containing disinfectants. The present invention relates to a pharmaceutical composition capable of sterilizing and disinfecting human fingers and skin containing ethanol. The pharmaceutical composition is provided as an emulsified composition such as a hand cream containing 10 to 23% by weight of ethanol or a milky liquid containing 45% by weight of ethanol as a pump or aerosol.

グルコン酸クロロヘキシジンは、1950年代に英国で開発された強い抗菌活性を有する強塩基性物質である。その作用機序は、低濃度域では細菌の細胞膜に障害を与え、細胞質成分の不可逆的漏出や酵素阻害を起こし、高濃度領域では細胞内の蛋白質や核酸の沈着を起こすことにより、殺菌或いは抗菌活性を示す。現在、グルコン酸クロロヘキシジンは多くの手指衛生製品に処方されており、手指・皮膚の消毒、手術部位の皮膚消毒、医療用具の消毒等に水溶液或いはエタノール溶液で使用されている(非特許文献1)。
また、CDC(米国疾病管理予防センター)から発表された「保健医療現場における手指衛生のためのCDCガイドライン 2002」において、グルコン酸クロロヘキシジンは皮膚上の細菌数を有効に減少させ、活性の強い手指消毒剤として紹介されている(非特許文献2)。
Chlorohexidine gluconate is a strongly basic substance with strong antibacterial activity developed in the UK in the 1950s. The mechanism of action is to kill bacteria or antibacterial substances by damaging bacterial cell membranes at low concentrations, causing irreversible leakage of cytoplasmic components and enzyme inhibition, and by depositing intracellular proteins and nucleic acids at high concentrations. Shows activity. Currently, chlorohexidine gluconate is prescribed in many hand hygiene products, and is used in aqueous solution or ethanol solution for disinfection of fingers and skin, skin disinfection of surgical sites, disinfection of medical devices, etc. (Non-patent Document 1) .
In addition, according to “CDC Guidelines 2002 for Hand Hygiene in Health and Medical Care” published by CDC (American Center for Disease Control and Prevention), chlorohexidine gluconate effectively reduces the number of bacteria on the skin and is highly active hand disinfection. It has been introduced as an agent (Non-patent Document 2).

また、従来からグルコン酸クロロヘキシジンは、殺菌消毒剤としてはその持続時間が長いことから世界の医学界で推奨されてきた。また、その製剤としては、高濃度エタノール(60〜80%)を含有する速乾性手指消毒剤として液剤、ゲル剤が医療従事者等に利用されてきた。しかし、高濃度エタノールによる殺菌直接効果は強いものの、高濃度エタノールによる手指の皮脂流失・皮脂量減少により医療従事者に手あれを生じさせ、荒れた角質は病原菌を付着させる原因になるとともに、アルコールによる刺激が手指の消毒義務が怠りがちになり二次感染を引き起こす原因の一つとされてきた。未だ医療従事者の50%が手荒れに悩んでいるのが現状である。  In addition, chlorohexidine gluconate has been conventionally recommended in the medical world since it has a long duration as a disinfectant. Moreover, as the preparation, a liquid agent and a gel agent have been used by medical workers and the like as a quick-drying hand disinfectant containing high-concentration ethanol (60 to 80%). However, although the direct sterilization effect by high-concentration ethanol is strong, the high-concentration ethanol causes hand sebum drainage and the decrease in the amount of sebum, which causes the medical staff to get rough, and the rough keratin causes the pathogenic bacteria to adhere, and alcohol causes Stimulation has been one of the causes of secondary infections, as it tends to neglect the duty to disinfect hands. The current situation is that 50% of medical workers still suffer from rough hands.

さらに看護士の約25%が手指に皮膚炎の兆候を持ち、85%もの人が皮膚に問題を持った経験があると報告されている(非特許文献3)。手指衛生剤や洗浄剤を繰り返し使用すると、医療従事者の慢性刺激性接触皮膚炎を引き起こす重要な原因となる。すなわち、角層タンパクの変性を引き起こし、細胞内脂質を変化させ、角化細胞の結合を減少させ、角層の保湿性を消失し、皮膚にダメージを与える。皮膚障害を受けた手指には肌荒れ、落屑、亀裂が生じ皮膚細菌叢の変化を起こし、ブドウ球菌やグラム陰性桿菌の定着を増加させ、人から人へ伝播の結果、院内感染拡大等の危険性がある。  Furthermore, it is reported that about 25% of nurses have signs of dermatitis on their fingers and as many as 85% have experience with skin problems (Non-patent Document 3). Repeated use of hand hygiene and cleaning agents is an important cause of chronic irritant contact dermatitis in health care workers. That is, it causes degeneration of stratum corneum proteins, changes intracellular lipids, decreases keratinocyte binding, loses the moisture retention of the stratum corneum, and damages the skin. Dangerous skin, desquamation, and cracks in skin damaged hands cause skin bacterial flora, increase staphylococcal and gram-negative bacilli colonization, and spread from person to person, resulting in the spread of nosocomial infections There is.

この解決策としてハンドクリームの使用が推奨されているが、医療現場では頻繁に消毒行為が行う必要性があるため、効果は不十分である。解決策として湿潤剤等が配合された製剤の特許文献に開示され、手指消毒剤として製品化されているものがあるが、既存製品ではいずれも、手あれの予防効果が期待できるには程遠い実情である(特許文献1〜5)。  The use of hand cream is recommended as a solution to this, but the effect is insufficient because of the necessity of frequent disinfection in the medical field. As a solution, there are those disclosed in the patent literature of preparations containing a wetting agent, etc., and commercialized as hand sanitizers, but all existing products are far from being able to expect a preventive effect on hand. Yes (Patent Documents 1 to 5).

同時に、液剤は効果持続時間が長いものの高濃度エタノールによる手あれを誘発し、ゲル剤は増粘剤により手荒れの誘発は多少抑えられるものの塗布直後効果が弱いこと、ローション剤は、持続時間が短いことなど、殺菌直後効果、持続効果、手荒れの抑制と全てを満足させる製剤はこれまで得られていなかった。  At the same time, although the liquid preparation has a long duration of effect, it induces hand-shaking due to high-concentration ethanol, while the gel preparation has a slight effect immediately after application, although the induction of hand roughening is somewhat suppressed by the thickener, and the lotion preparation has a short duration. So far, no preparation has been obtained that satisfies all of the effects immediately after sterilization, the sustained effect, and the suppression of rough hands.

院内感染は大きな問題であるが、近年は高齢化に伴い介護問題も深刻でこれによって介護従事者の手指の消毒も重要な課題である。  Nosocomial infections are a major problem, but in recent years nursing care problems have become more serious with the aging of society, and disinfection of the hands of care workers is an important issue.

医療現場での手指消毒剤は、これまでエタノールを高濃度(60〜80%)含有するカチオン殺菌消毒剤グルコン酸クロロヘキシジン0.2〜0.5%を主剤とした液剤、ゲル剤が汎用されている。これは、エタノールの蛋白変性作用による直接作用とグルコン酸クロルヘキシジンの持続性のある殺菌効果による。高濃度エタノール含有液剤は、使用時の液垂れによる床の汚染、損傷および多量のエタノールによる皮脂量流失・減少による手あれが大きな問題であった。手あれは、皮膚への菌の付着が多く、二次感染を引き起こす悪循環の原因になっている。この解決策として湿潤剤を組み合わせた液剤また皮脂量の損失を防ぐ目的でカーボポール等の増粘剤を利用した液垂れのない高濃度エタノール含有ゲル剤も開発されている。しかし、病院従事者、介護従事者らはこれらの高濃度エタノール含有製剤を感染防止の徹底から頻回に使用せざるを得ないため、手あれ防止の問題は未だ解決せず、市販のハンドクリームを多用しているのが現状である。  As a hand sanitizer in the medical field, a liquid agent and a gel agent having a main ingredient of 0.2 to 0.5% of cation sterilizing disinfectant chlorohexidine gluconate containing ethanol at a high concentration (60 to 80%) have been widely used. Yes. This is due to the direct action of the protein denaturing action of ethanol and the persistent bactericidal effect of chlorhexidine gluconate. High-concentration ethanol-containing liquids have had major problems with floor contamination due to dripping during use, damage, and hand-off due to loss or reduction of sebum volume due to a large amount of ethanol. It is a cause of a vicious circle that causes secondary infections due to the attachment of bacteria to the skin. As a solution to this problem, a liquid agent combined with a wetting agent or a gel agent containing a high concentration ethanol without dripping using a thickener such as carbopol has been developed for the purpose of preventing loss of sebum amount. However, hospital workers and caregivers have to use these high-concentration ethanol-containing preparations frequently because of thorough infection prevention. The current situation is that it is heavily used.

市販のハンドクリームはべたつき感が強く、特有の臭いや製品によっては患者に注射する際に手がすべる等の問題があり、実際には業務の合間に使用せざるをえない制限があった。また、ハンドクリーム含有成分は成分表示されている場合が多いが、クロロヘキシジンは陽イオン性分子であるためその活性は天然石鹸、種々の無機イオン、陰イオン性乳化剤等によりその効果は減弱されると報告されているが、表示成分を見分けるのは容易ではない(非特許文献4)。  Commercial hand creams have a strong stickiness, and there are problems such as slipping of hands when injecting to patients depending on the specific odors and products, and there are actually restrictions that must be used between work. In addition, hand cream containing ingredients are often listed as ingredients, but chlorohexidine is a cationic molecule, so its activity is attenuated by natural soaps, various inorganic ions, anionic emulsifiers, etc. Although reported, it is not easy to distinguish display components (Non-Patent Document 4).

医療従事者らは、手あれ改善を目的として市販のハンドクリームを多用している。海外では消毒剤販売会社にハンドクリームを無償で提供する義務があるとまで指摘されている。更に、手術執刀医は、長時間手術する場合、術中頻繁にゴム手袋の交換を求められる。そのため、持続効果を有し、手あれがより少なく持続効果のある手指消毒剤が望まれていた。  Medical workers frequently use commercially available hand creams for the purpose of improving touch. It has been pointed out that there is an obligation to provide hand cream free of charge to disinfectant sales companies overseas. Furthermore, when operating for a long time, a surgeon is required to change rubber gloves frequently during the operation. Therefore, there has been a demand for a hand sanitizer that has a long-lasting effect and has less hand-shaking and has a long-lasting effect.

本発明の課題は、手指の消毒効果と手荒れ防止効果を兼ね備えた新規な医薬組成物を提供することにある。  The subject of this invention is providing the novel pharmaceutical composition which has the disinfection effect of fingers and the rough hand prevention effect.

本発明者らは、市販ハンドクリーム処方内容(添加物)を検討し、グルコン酸クロロヘキシジンの安定性、効果に悪影響を及ぼす添加物をスクリーングした。同時に乳化物の可能なエタノール含有率と殺菌・消毒効果、持続時間を検討した。そして、グルコン酸クロロヘキシジン或いはその塩を0.1〜1%およびエタノール、油分、湿潤剤を含有するクリーム製剤であり、手指消毒評価法で是認される殺菌効果において少なくとも3時間殺菌効果を持続し、手荒れ防止効果も示し、上記課題が解決されることを見出した。  The present inventors examined the contents (additives) of a commercially available hand cream and screened for additives that adversely affect the stability and effect of chlorohexidine gluconate. At the same time, the possible ethanol content, sterilizing / disinfecting effect and duration of the emulsion were investigated. And it is a cream preparation containing 0.1 to 1% chlorohexidine gluconate or a salt thereof, ethanol, oil, and a wetting agent, and maintains the bactericidal effect for at least 3 hours in the bactericidal effect approved by the hand disinfection evaluation method, It has also been found that the above-mentioned problems can be solved by showing the effect of preventing rough hand.

すなわち、本発明は、ビグアナイド系カチオン殺菌消毒剤グルコン酸クロロヘキシジン又はその塩、エタノール、油性基剤、高級脂肪族アルコール、親油性と親水性の非イオン界面活性剤、水溶性多価アルコール、及びグルコン酸を含み、前記グルコン酸クロロヘキシジン濃度は殺菌消毒剤全重量あたり0.1〜1重量%であり、かつ、手指消毒評価による殺菌効果が少なくとも3時間持続することを特徴とする医薬組成物である。  That is, the present invention relates to a biguanide cationic disinfectant chlorohexidine gluconate or a salt thereof, ethanol, an oil base, a higher aliphatic alcohol, a lipophilic and hydrophilic nonionic surfactant, a water-soluble polyhydric alcohol, and glucone. The pharmaceutical composition is characterized in that it contains an acid, the chlorohexidine gluconate concentration is 0.1 to 1% by weight based on the total weight of the disinfectant, and the disinfecting effect by hand disinfection evaluation lasts for at least 3 hours. .

本発明の医薬組成物は、ハンドクリーム剤等の乳化組成物、エアゾール剤等の乳状液剤として提供される。  The pharmaceutical composition of the present invention is provided as an emulsified composition such as a hand cream and a milky liquid such as an aerosol.

前記医薬組成物において、エタノール濃度は、クリーム剤においては殺菌消毒剤全重量あたり10〜23重量%、乳状液剤においては上限45重量%であることが好ましい。  In the pharmaceutical composition, the ethanol concentration is preferably 10 to 23% by weight based on the total weight of the bactericidal disinfectant for creams and 45% by weight for the milky liquid.

本発明の医薬組成物には、さらに以下の成分が含有されていてもよい:

本発明の医薬組成物をクリーム剤として処方する場合、偏光顕微鏡観察での乳化粒子径が約50μm以下の大きさの結晶性または球状粒子が均一に分散していることが望ましい。  When the pharmaceutical composition of the present invention is formulated as a cream, it is desirable that crystalline or spherical particles having an emulsified particle diameter of about 50 μm or less as observed with a polarizing microscope are uniformly dispersed.

以上のとおり、本発明は、有効成分として殺菌効果の持続性が期待できるグルコン酸クロロヘキシジン或いはその塩と低濃度アルコールを含有するクリーム製剤であり、手指の消毒効果と共に手荒れ防止効果を兼ね備えた新規な医薬組成物である。  As described above, the present invention is a cream preparation containing chlorohexidine gluconate or a salt thereof and a low-concentration alcohol, which can be expected to have a sustained bactericidal effect as an active ingredient, and has a novel antibacterial effect as well as a hand disinfection effect. It is a pharmaceutical composition.

本発明にかかる医薬組成物は、医療現場では高濃度エタノールによる殺菌効果の要望もあることから、グルコン酸クロロヘキシジンを主成分としエタノール濃度が45重量%(容量換算で約60%)を上限とする乳状液剤、あるいは使用が簡便なポンプ式またはエアゾールとして提供される。  Since the pharmaceutical composition according to the present invention has a demand for a bactericidal effect by high-concentration ethanol in the medical field, the upper limit is 45% by weight of ethanol concentration (about 60% in terms of volume) with chlorohexidine gluconate as the main component. It is provided as a milky solution, or a pump type or aerosol that is easy to use.

本発明は、従来手指消毒のために多用されてきた速乾性の高濃度エタノール液剤、ゲルの欠点を解消するとともに、手あれ改善を目的に使用されてきた市販のハンドクリームの利点を応用し、持続効果を減弱することなく両者を最適条件で組み合わせることに成功した。本発明によれば、殺菌効果への悪影響が懸念される市販のハンドクリームの使用も必要がなく、同時に経済性も確保される。  The present invention eliminates the disadvantages of fast-drying high-concentration ethanol solutions and gels that have been frequently used for hand sterilization and applies the advantages of commercially available hand creams that have been used for improving hand-shaking, and continues. We succeeded in combining the two under the optimum conditions without diminishing the effect. According to the present invention, it is not necessary to use a commercially available hand cream that is feared to have an adverse effect on the bactericidal effect, and at the same time, economic efficiency is ensured.

本発明の医薬組成物は、表1、2、3の実施例に示すとおり、3時間の持続効果はもとより医療行為の妨げにならない使用感の良い乳化組成物調整の基本構成である。主剤であるグルコン酸クロロヘキシジンの濃度は、0.1%では直後効果はもとより3時間目までの持続効果が得られ、0.2%以上では6時間目でも持続効果が得られた。なお、外傷殺菌を適応とした0.1%濃度の市販品は、ワセリン、グリセリンの多量配合およびエタノール無配合のためか、殺菌作用は全く認められなかった。  The pharmaceutical composition of the present invention, as shown in the Examples of Tables 1, 2, and 3, is a basic composition for preparing an emulsified composition with a good feeling of use that does not interfere with medical practice as well as a sustained effect for 3 hours. When the concentration of chlorohexidine gluconate, which is the main agent, was 0.1%, not only the immediate effect but also the sustained effect up to the third hour was obtained, and when it was 0.2% or more, the sustained effect was obtained even at the sixth hour. In addition, the 0.1% concentration commercial product that was adapted for trauma sterilization was not recognized to have any bactericidal action, probably because it contained a large amount of petrolatum, glycerin and no ethanol.

殺菌効果は、アルコール配合濃度10%未満でも直後の効果はみられるが、表1に示すとおり10重量%以上で医療現場で求められる現行の試験法での3時間目迄の持続性効果がみられる。またエタノール濃度25重量%では40℃の加速試験で2週間後にボトムクリア(2層分離)がみられることからハンドクリームタイプではエタノール濃度は10〜23重量%、望ましくは製造上の防爆設備を考慮すると15重量%程度が最適である。  The bactericidal effect is observed immediately after the alcohol concentration is less than 10%, but as shown in Table 1, the effect of sustaining up to the third hour in the current test method required in the medical field is seen at 10% by weight or more. It is done. In addition, when the ethanol concentration is 25% by weight, bottom clear (two-layer separation) is observed after 2 weeks in the accelerated test at 40 ° C, so the hand cream type has an ethanol concentration of 10 to 23% by weight, preferably considering explosion-proof equipment for manufacturing. Then, about 15% by weight is optimal.

表1,2,3に示すとおり、乳化安定剤としてラウリルアルコール(C12)、ミリスチルアルコール(C14),パルミチルアルコール(C16)、ステアリルアルコール(C18),ベヘニルアルコール(C22)の飽和・不飽和脂肪族高級アルコールが配合可能である。その配合量は、1〜4%が望ましい。また、温度溶解性を考慮するとセトステアリルルコール、ステアリルアルコールが適当である。  As shown in Tables 1, 2 and 3, as emulsion stabilizers, saturated and unsaturated aliphatics of lauryl alcohol (C12), myristyl alcohol (C14), palmityl alcohol (C16), stearyl alcohol (C18), and behenyl alcohol (C22) Higher alcohol can be blended. The blending amount is desirably 1 to 4%. In view of temperature solubility, cetostearyl alcohol and stearyl alcohol are suitable.

表1,2,3に示すとおり、本発明で用いられる非イオン界面活性剤は、HLB値8以下の親油性界面活性剤およびHLB値10以上の親水性非イオン界面活性剤の組み合わせで使用する。具体的には、ハンドクリームでは皮膚安全性の高い親油性界面活性剤としてモノステアリン酸グリセリンと付加モル数の多いPOE(60)硬化ヒマシ油の組み合わせが最適である。更にPOE(30)ベヘニルエーテル等のポリオキシエチレンアルキルエーテル等をHLB(Hydrophile−Lipophile Balance)を考慮して2種以上で使用することができる。その重量総和は全重量の2〜4%で十分な乳化物が得られる。  As shown in Tables 1, 2, and 3, the nonionic surfactant used in the present invention is used in combination of a lipophilic surfactant having an HLB value of 8 or less and a hydrophilic nonionic surfactant having an HLB value of 10 or more. . Specifically, in hand cream, a combination of glyceryl monostearate and POE (60) hydrogenated castor oil having a large number of added moles as a lipophilic surfactant having high skin safety is optimal. Furthermore, polyoxyethylene alkyl ethers such as POE (30) behenyl ether can be used in two or more kinds in consideration of HLB (Hydrophile-Lipophile Balance). The total weight is 2 to 4% of the total weight, and a sufficient emulsion can be obtained.

また、エタノール40〜45重量%配合の乳状液においては、親油性非イオン界面活性剤としてはグリセリン脂肪酸エステルであるモノステアリン酸グリセリンとポリグリセリン脂肪酸エステルの組み合わせと親水性非イオン界面活性剤としてPOE(40、50モル)硬化ヒマシ油等のポリオキシエチレンヒマシ油・硬化ヒマシ油、ステアリン酸PEG40等のポリエチレングリコール脂肪酸エステルの単独または組み合わせが最適である。
その重量総和は、全重量の4〜8%で適当な乳化物が得られる。
Further, in a milky liquid containing 40 to 45% by weight of ethanol, the lipophilic nonionic surfactant is a combination of glycerin fatty acid ester glyceryl monostearate and polyglycerin fatty acid ester, and POE is a hydrophilic nonionic surfactant. (40, 50 mol) Polyoxyethylene castor oil / hardened castor oil such as hydrogenated castor oil, or polyethylene glycol fatty acid ester such as stearic acid PEG40 alone or in combination is most suitable.
An appropriate emulsion can be obtained when the total weight is 4 to 8% of the total weight.

表1に示すとおり、湿潤剤として多用される水溶性多価アルコールのなかで微生物の栄養源とされ、薬効に悪影響を及ぼす3価アルコールのグリセリンを除く2価のグリセロール、ジエチレングリコール、プロピレングリコール、ジプロピレングリコール、及び1,3ブチレングリコール等は薬効に影響せず、皮膚湿潤剤として有用である。配合量は5〜15重量%が望ましい。  As shown in Table 1, dihydric glycerol, diethylene glycol, propylene glycol, dihydride, which is used as a nutrient source for microorganisms among water-soluble polyhydric alcohols frequently used as a wetting agent, except for glycerin, a trihydric alcohol that adversely affects medicinal properties. Propylene glycol, 1,3 butylene glycol and the like do not affect the drug efficacy and are useful as skin moisturizers. The blending amount is desirably 5 to 15% by weight.

グルコン酸クロロヘキシジンは水に不溶であるがグルコン酸2分子とイオン結合し水溶性となる陽イオン性の殺菌消毒剤である。そのため無機イオン、イオン性界面活性剤等、イオンの存在でその活性が減弱することは公知の事実である。そのpH安定領域は4〜6.5とされ、その調整として過量のグルコン酸を主剤量(0.1〜1%)の約2倍量、0.2〜2%配合することで安定性と薬効の持続性が確保された。  Chlorhexidine gluconate is a cationic disinfectant that is insoluble in water but ionically bonds with two molecules of gluconic acid and becomes water-soluble. Therefore, it is a known fact that the activity is attenuated by the presence of ions such as inorganic ions and ionic surfactants. The pH stable region is 4 to 6.5, and as an adjustment, an excess amount of gluconic acid is added by about twice the amount of the main agent (0.1 to 1%), and 0.2 to 2%. Sustained medicinal properties were secured.

油性基剤は、使用感に大きな影響を及ぼす。基剤としては表1,2,3の実施例に見られるとおり、トリオクタン酸グリセリン、流動パラフィン、シリコン油、ワセリン、スクワラン、及びホホバ油等の植物油、マクロゴール等を殺菌消毒剤全重量%に対して各1〜5%の範囲で適当に配合することで使用感が調整できる。また、高級脂肪酸は乳化安定剤として全重量%に対して0.5〜2%配合することができる。  The oily base has a great influence on the feeling of use. As seen in the examples in Tables 1, 2, and 3, the base oil is vegetable oil such as glycerin trioctanoate, liquid paraffin, silicon oil, petrolatum, squalane, jojoba oil, macrogol, etc. On the other hand, a feeling of use can be adjusted by mix | blending suitably in the range of 1 to 5% of each. Further, the higher fatty acid can be blended in an amount of 0.5 to 2% based on the total weight% as an emulsion stabilizer.

粒子径で約50mμの粒子が散見されないクリームは全く薬効が確認されなかったことから、クリーム剤の乳化粒子径は偏光顕微鏡観察で約50μmの大きさであって、その結晶性または球状粒子が均一に分散している製剤が好ましい。  Creams in which particles with a particle size of about 50 mμ were not scattered were found to have no medicinal effects, so the emulsified particle size of the cream was about 50 μm as measured with a polarizing microscope, and the crystalline or spherical particles were uniform. A preparation dispersed in is preferred.

乳化法は、実施例全てにおいて油相(表1では成分(1)〜(7)、表2,3では(8)まで)と水相を加熱溶解後70℃前後で通常のホモミキサーで攪拌、冷却する他、その他、非水乳化法、2段乳化法など乳化法によって制限されるものではなく、何れの方法でも調整可能である。また、水相に油相を添加してO/W型、水相を油相に添加してW/O型の何れでも薬効に影響を及ぼすものではない。エアゾール剤は、全重量に対して5%のLPガスを配合することで得られる。  In all the examples, the emulsification method involves stirring the oil phase (components (1) to (7) in Table 1, up to (8) in Tables 2 and 3) and the aqueous phase with a normal homomixer at around 70 ° C. after heating and dissolving. In addition to cooling, the method is not limited by an emulsification method such as a non-aqueous emulsification method or a two-stage emulsification method, and any method can be used. Neither the oil phase is added to the water phase and the O / W type, and the water phase is added to the oil phase and the W / O type does not affect the drug efficacy. The aerosol can be obtained by blending 5% LP gas with respect to the total weight.

殺菌消毒効果の判定としては静菌作用として黄色ぶどう球菌を対象にMIC(最小発育阻止濃度)を測定し、グルコン酸クロロヘキシジンの作用が確認された。  As a determination of the bactericidal disinfection effect, MIC (minimum growth inhibitory concentration) was measured for Staphylococcus aureus as a bacteriostatic action, and the action of chlorohexidine gluconate was confirmed.

手指殺菌消毒効果の評価法として、グローブジュース法、パームスタンプ法等が知られるが、今回、本製剤の手指消毒効果の評価法として用いたグローブ・パームスタンプ法は、グローブジュース法の簡便法で、通常の石鹸で手洗い後、本発明品であるクリームまたは乳状液殺菌剤による両手消毒直後、3時間後に手形培地(例えばSCD培地、SCDLP培地等)に片方の手掌全体を押し付けスタンプ(ハンドぺたんチェック;栄研器材社の登録商標)する。スタンプ採取した手形培地を約35℃で18時間培養し、培養後に出現する菌数を測定する消毒評価法である。消毒前の手掌の菌数も前記と同様に測定しベースラインとする。  The glove juice method, palm stamp method, etc. are known as methods for evaluating the hand sterilization effect. The glove / palm stamp method used for evaluating the hand sanitization effect of this preparation is a simple method of the glove juice method. After hand washing with normal soap, immediately after disinfecting both hands with the cream or milky liquid disinfectant of the present invention, 3 hours later, press the entire palm of one hand against the handprint medium (for example, SCD medium, SCDLP medium, etc.). A registered trademark of Eiken Equipment Co., Ltd.). This is a disinfection evaluation method in which a stamp-collected handprint medium is cultured at about 35 ° C. for 18 hours, and the number of bacteria appearing after the culture is measured. The number of germs in the palm before disinfection is also measured in the same manner as described above to obtain a baseline.

消毒効果は、消毒前菌数に対する消毒後の菌数の減少率等で行なうことができる。減少率は下記式によって求められ、減少率が90%以上の場合に殺菌効果(表1,2,3の有効)が是認される。今回はクリーム剤または乳状液剤を塗布直後、3時間後とも90%以上の場合を有効とした。  The disinfection effect can be performed by a reduction rate of the number of bacteria after disinfection with respect to the number of bacteria before disinfection. The reduction rate is obtained by the following formula. When the reduction rate is 90% or more, the bactericidal effect (effective in Tables 1, 2 and 3) is approved. This time, the case where it was 90% or more immediately after application of the cream or milky liquid and after 3 hours was considered effective.

エタノールは蛋白変性作用を有し菌に対して直接作用を有するので、殺菌消毒剤には有用であるが、乳化物には溶解目的以外で使用されることはなく、配合しても5%以下である。主剤、高級アルコール、皮膚安全性の高い親油性、親水性非イオン界面活性剤、油性基剤の組み合わせでアルコール含有率と効果を検討した結果、エタノール濃度は10重量%以上から持続性のある効果は濃度依存であることが判明した(表1)。また、ハンドクリーム処方に湿潤剤として汎用されているグリセリン、高級脂肪酸、ワセリン等は配合量によってはグルコン酸クロロヘキシジンの効果に悪影響を示すことが判明した(表1)。  Since ethanol has a protein-denaturing action and a direct action on bacteria, it is useful as a disinfectant, but it is not used in emulsions for purposes other than dissolution, and even if blended, it is 5% or less It is. As a result of examining the alcohol content and the effect of a combination of the main agent, higher alcohol, lipophilicity with high skin safety, hydrophilic nonionic surfactant and oil base, the ethanol concentration is 10% by weight or more and has a sustained effect Was found to be concentration dependent (Table 1). It was also found that glycerin, higher fatty acids, petrolatum, etc., which are widely used as wetting agents in hand cream formulations, have an adverse effect on the effect of chlorohexidine gluconate depending on the blending amount (Table 1).

同時にグルコン酸を過剰に配合することとカチオン性のグルコン酸クロロヘキシジンの安定性に影響を及ぼさないものとして皮膚安全性の高い非イオン界面活性剤の組み合わせであれば殺菌作用に影響がないことが判明した(表1,2,3)。  At the same time, it was found that the combination of excessive gluconic acid and the stability of cationic chlorohexidine gluconate did not affect the bactericidal effect if it was a combination of nonionic surfactants with high skin safety (Tables 1, 2 and 3).

本発明の医薬組成物は持続的な手指消毒効果と手荒れ防止効果を兼ね備えている。したがって、手荒れがより少なく持続効果のある手指消毒剤が望まれている医療現場において有用である。  The pharmaceutical composition of the present invention has a continuous hand disinfection effect and a rough hand prevention effect. Therefore, it is useful in a medical field where a hand sanitizer with less hand roughness and a sustained effect is desired.
