Description

本発明は、洗濯物の除菌・消臭、食品工場や病院などにおいて殺菌・抗菌などを目的として使用される抗菌性洗剤組成物に関し、さらに詳しくは、洗濯に使用される洗剤や柔軟剤、クリーニング用洗浄剤、食品工場や病院などの壁や床などに用いられる洗浄剤などとして有利に使用される抗菌性洗剤組成物に関する。   The present invention relates to antibacterial detergent compositions used for the purpose of disinfecting and deodorizing laundry, sterilizing and antibacterial in food factories and hospitals, and more specifically, detergents and softeners used for washing, The present invention relates to an antibacterial detergent composition that is advantageously used as a cleaning detergent, a detergent used for walls and floors of food factories and hospitals, and the like.

従来、医療現場で使用された衣類、敷布などには、血液、体液、脂肪などによる汚れとともに病原菌やウイルスなどにより汚染されており、このような衣類、敷布などには洗浄とともに殺菌、抗菌、除菌、消臭などの処理を行うため、殺菌剤を含有した洗剤が使用されている。また、クリーニングにおいても、衣類の汚染を防ぎ衛生的な状態で仕上げるため、通常、洗剤とともに殺菌剤が使用されている。   Traditionally, clothes and bedclothes used in medical settings are contaminated with pathogens and viruses as well as dirt from blood, body fluids, fats, etc. Such clothes and bedclothes are washed and sterilized, antibacterial and antibacterial. A detergent containing a bactericide is used to treat bacteria, deodorant and the like. In cleaning, a disinfectant is usually used together with a detergent in order to prevent contamination of clothing and finish in a hygienic state.

近年、清潔指向からか、一般家庭においても、衣類、敷布などの洗浄とともに除菌、消臭を行うために殺菌剤を含有する洗剤、柔軟剤などが市場に出回っている。しかし、これらの洗濯用抗菌剤の中には、長期間使用すると細菌の耐性化を引き起こし、除菌や消臭の効果がなくなるものがある。   In recent years, detergents and softeners containing a bactericide have been put on the market in order to disinfect and deodorize clothes, mattresses, etc., as well as cleaning clothes and mattresses. However, some of these antibacterial agents for washing cause resistance to bacteria when used for a long period of time, and the effects of sterilization and deodorization are lost.

病院内においては、MRSA(メチシリン耐性黄色ブドウ球菌)などの耐性菌が、体の弱っている入院患者に感染し、大きな社会問題になっており、壁や床などに用いる洗浄剤としては、耐性菌が発現しない殺菌剤を含有した洗浄剤を使用することが望まれている。また、食品工場では、耐性菌のみならず細菌自体の存在が問題になるので、耐性菌が発現しないことは勿論のこと、広い抗菌活性スペクトルを有する安全性の高い抗菌剤が望まれている。   In hospitals, resistant bacteria such as MRSA (methicillin-resistant Staphylococcus aureus) infect hospitalized patients with weak bodies, which has become a major social problem. As a cleaning agent for walls and floors, It is desired to use a cleaning agent containing a bactericide that does not express bacteria. In food factories, the presence of not only resistant bacteria but also bacteria themselves is a problem, and therefore, a highly safe antibacterial agent having a wide antibacterial activity spectrum is desired as well as resistant bacteria are not expressed.

試験例1
前記化合物(1)〜化合物(4)および市販品であるセチルピリジニウムクロライド(CPC)の薬剤耐性化試験を4種の細菌(Pseudomonas aeruginosa ATCC 10145、Escherichia coli K12 3110、Bacillus subtilisATCC 6633、Staphylococcus aureus IFO 12732)を用いて行なった。すなわち、各細菌をL-broth(5ml)に植菌し、37℃で18時間培養後、Nutrient Broth液体培地希釈法に従いMIC(最小発育阻止濃度)の測定を行なった。次に、MIC判定時において、菌の発育を阻止していた最小の薬剤濃度(MIC)より低濃度の菌液(菌の増殖が確認される最大薬剤濃度の菌液)を使用し、菌数を約106個/mlに調製した後、再度MICの測定を行なった。この操作を7回くり返し、各操作回数におけるMIC値を記録し、耐性菌の発現の有無を確認した。その結果を下記表1に示す。
The present invention will be described more specifically with reference to the following test examples and examples, but the present invention is not limited to these examples.
Test example 1
The compound (1) to compound (4) and a commercially available cetylpyridinium chloride (CPC) were tested for drug resistance using four types of bacteria (Pseudomonas aeruginosa ATCC 10145, Escherichia coli K12 3110, Bacillus subtilis ATCC 6633, Staphylococcus aureus IFO 12732 ). Specifically, each bacterium was inoculated into L-broth (5 ml), cultured at 37 ° C. for 18 hours, and then measured for MIC (minimum growth inhibitory concentration) according to the Nutrient Broth liquid medium dilution method. Next, at the time of MIC determination, a bacterial solution having a concentration lower than the minimum drug concentration (MIC) that prevented the growth of the bacteria (MIC solution having the maximum drug concentration at which bacterial growth is confirmed) is used. Was adjusted to about 10 6 cells / ml, and the MIC was measured again. This operation was repeated 7 times, the MIC value at each operation number was recorded, and the presence or absence of expression of resistant bacteria was confirmed. The results are shown in Table 1 below.

Figure 2006022140

上記の表1から明らかなように、CPCでは、操作回数が増えるにつれ、4種の細菌すべてに対するMICの値が増加している、すなわち、耐性菌が発現しているのに対し、本発明で使用する前記化合物(1)〜化合物(4)では、4種の細菌すべてにおいて、7回操作を繰り返した後でも初期のMIC値と殆ど変わらず、細菌の耐性化が起こっていないことがわかる。   As apparent from Table 1 above, in CPC, as the number of manipulations increases, the value of MIC for all four bacteria increases, that is, resistant bacteria are expressed. In the compounds (1) to (4) to be used, it can be seen that, in all four types of bacteria, even after the operation was repeated seven times, the initial MIC value was hardly changed, and bacterial resistance did not occur.

Examples Each component of the composition (mass%) shown in Table 3 below was sufficiently stirred and mixed to obtain four types of antibacterial detergent compositions A to D of the present invention.
Figure 2006022140

上記の各抗菌性洗剤組成物の殺菌効力の確認を以下の通りにして行った。すなわち、Escherichia coli IFO 3972(大腸菌)を、NA培地に接種し、これを35℃にて20時間の前培養を行うことによって生育させた菌体を滅菌精製水中に懸濁させ、生菌数約106個/mlの菌液を得た。この菌液0.1mlを上記の表3に示される抗菌性洗剤組成物A〜Dが滅菌精製水を用いて1,000倍に希釈された各々9.9mlに添加してよく混合し、試験水を作製した。これらの試験水を室温にて、5分、30分、および60分間保存した時点で、各々の試験水中から1ml採取した後、これを直ちに各々9mlのSCDLP培地に混合し、この希釈液中の生菌数を計測した。結果を下記表4に示す。 The bactericidal efficacy of each antibacterial detergent composition was confirmed as follows. That is, Escherichia coli IFO 3972 (Escherichia coli) was inoculated into NA medium, and the cells grown by pre-culturing at 35 ° C. for 20 hours were suspended in sterilized purified water, and the number of viable bacteria was reduced. A bacterial solution of 10 6 cells / ml was obtained. Add 0.1 ml of this bacterial solution to 9.9 ml each of the antibacterial detergent compositions A to D shown in Table 3 diluted 1,000 times using sterilized purified water, and mix well. Water was made. When these test waters were stored at room temperature for 5 minutes, 30 minutes, and 60 minutes, 1 ml was taken from each test water, and then immediately mixed with 9 ml of each SCDLP medium. Viable count was counted. The results are shown in Table 4 below.

上記の表4から明らかなように、抗菌性洗剤組成物A〜Dは殺菌力を示すことがわかる。
Figure 2006022140
As apparent from Table 4 above, it can be seen that the antibacterial detergent compositions A to D exhibit bactericidal power.

本発明の抗菌性洗剤組成物に抗菌剤として配合される前記一般式(1)で表される化合物は、人や自然環境に対する安全性が高い抗菌剤であり、耐性菌が出現することなくかつ広い抗菌活性スペクトルを有する。また、MRSAに対して低濃度で効果を示す。従って、洗剤として長期使用した場合にも耐性菌の発現が認められず、殺菌、抗菌、除菌、消臭効果を期待することができる。   The compound represented by the general formula (1) blended as an antibacterial agent in the antibacterial detergent composition of the present invention is an antibacterial agent that is highly safe against humans and the natural environment without causing resistant bacteria and Has a broad spectrum of antibacterial activity. In addition, MRSA is effective at a low concentration. Therefore, even when used as a detergent for a long time, the expression of resistant bacteria is not recognized, and sterilization, antibacterial, sterilization, and deodorizing effects can be expected.
