To investigate the potential use of oregano essential oil as an antimicrobial agent in liquid soap for hand washing and for food contact surface cleaning.
Oregano essential oil (O.E.O.) was emulsified in liquid detergent solution. This was challenge tested against a commercial antimicrobial soap in hand washing trials using natural flora. Soap with O.E.O. was as effective as the commercial antimicrobial soap at reducing aerobic plate count on the hands and more effective than plain soap with no additives. Cloths wetted with soap with O.E.O. were used to clean three different surfaces contaminated with four bacterial pathogens. For three of the four pathogens, the addition of 0·5% v/v O.E.O. to the soap solution enhanced cleaning performance and also reduced bacterial survival on the cloth after cleaning.
Oregano essential oil (0·5%) is effective as an antimicrobial additive to detergent solutions for hand washing and surface cleaning.
This preliminary study has shown that oregano essential oil is a potential alternative to antimicrobials used in various detergents, such as chloroxylenol and triclosan, which can have adverse environmental and health effects. Further development could lead to a commercial product.
研究牛至精油作为一种抗菌剂在用于手部清洗的液体皂和食品接触面清洁中的潜在用途。
将牛至精油（O.E.O.）乳化在液体洗涤剂溶液中。使用天然菌群在手洗试验中对这种抗菌皂进行了挑战性测试。含有 O.E.O.的肥皂在减少手上需氧平板计数方面与商业抗菌皂一样有效，并且比没有添加剂的普通肥皂更有效。用含有 O.E.O.的肥皂浸湿的布用于清洁三种不同表面上的四种细菌病原体。对于四种病原体中的三种，向肥皂溶液中添加 0.5%v/v 的 O.E.O.增强了清洁性能，并且在清洁后也减少了细菌在布上的存活。
牛至精油（0.5%）作为一种抗菌添加剂，可有效用于手部清洗和表面清洁的洗涤剂溶液中。
这项初步研究表明，牛至精油是一种替代氯二甲苯酚和三氯生等各种洗涤剂中使用的抗菌剂的潜在选择，这些抗菌剂可能对环境和健康有不利影响。进一步的开发可能会导致商业产品的出现。
