Assessment of the antibacterial activity of tea tree oil using the European EN 1276 and EN 12054 standard suspension tests

摘要: The activity of tea tree oil (TTO) and TTO-containing products was investigated according to the EN 1276 12054 European suspension methods. different concentrations TTO, a hygienic skin wash (HSW), an alcoholic (AHSW) hand rub (AHR) investigated. These formulations were assessed in perfect conditions with test, as well presence interfering substances against Staphylococcus aureus, Acinetobacter baumannii, Escherichia coli Pseudomonas aeruginosa. With latter same without TTO also control. AHR achieved >10(5)-fold reduction all four test organisms within 1-min contact time. AHSW >or=10(5)-fold A. baumannii after time S. E. P. aeruginosa 5-min efficacy appeared be dependent on formulation concentration tested, and, lastly, organism tested. Nevertheless, 5% >10(4)-fold cell numbers conditions. (5%) 0.001% Tween 80 significantly more active than aureus baumannii. time, numbers, respectively, >4 log10 used this study are now being tested using novel ex vivo method standard handwashing 1499.
