01 Jun 2010 Theoretical and Experimental Aspects of Microbicidal Activities of Hard Surface Disinfectants: Are Their Label Claims Based on Testing Under Field Conditions?
Although such surfaces are routinely disinfected, the testing and label claims of many common disinfectants do not reflect the realities of field use. This study addresses the disparity between disinfectant efficacy testing conditions and the actual conditions encountered in the field. The researchers compared the efficacy of a variety of disinfectant chemistries against Staphylococcus aureus and Pseudomonas aeruginosa, on both a hard surface as well as a hydrophobic (water-repelling) surface. AHP remained wet on the surfaces for an acceptable period of time, whereas quarternary ammonium compounds and bleach did not.
