Hard Surface Efficacy of PHMB / Quaternary Ammonium Chloride Blend Vs. Stabilized Chlorine Dioxide
[0176]The objective of this analysis was to examine the efficacy of various compositions against Staphylococcus aureus ATCC 6538 and Klebsiella pneumoniae ATCC 4352 after application to inanimate, non-porous, non-food contact surfaces.
Test Method:
Residual Self-Sanitizing Activity on Hard, Non-Porous Surfaces
[0177]Test Surface Preparation:[0178]Clean glass test surfaces were decontaminated by immersing in reagent alcohol and allowing to air dry at room temperature. The test surfaces were dried in sterile glass petri dishes containing 2 layers of Whatman No. 2 paper. Each petri dish had two surfaces in them and were dried for 1 day in a biological safety cabinet with the lids cracked open.
[0179]Test Surface Inoculation and Coating:[0180]The initial inoculum suspension was prepared by making 10−2 and 10−4 dilutions from a 48-54 hour broth culture of the test system. The 10−4 dilution was all...

Residual Self-Sanitizing Screen of Test Composition A
[0205]The objective of the analysis was to examine the residual self-sanitizing efficacy of against Staphylococcus aureus ATCC 6538 and Klebsiella pneumoniae ATCC 4352 after application to inanimate, non-porous, non-food contact surfaces.
Test Method:
Residual Self-Sanitizing Activity on Hard, Non-Porous Surfaces
Test System Preparation
[0206]1. At least three consecutive loop transfers of a 24 hour culture of Staphylococcus aureus ATCC 6538 and Klebsiella pneumoniae ATCC 4352 were performed in 10 mL of AOAC Synthetic broth or AOAC Nutrient broth (respectively) and incubated at 35° C.[0207]2. Initial Inoculum Suspension:
[0208]2.1 Vortex a 48-54 hour culture for 3-4 seconds.
[0209]2.2 Make two 1 / 100 dilutions in sterile PBDW and let stand for 15±1 minutes.[0210]3. Reinoculation Suspension:[0211]3.1 Vortex an 18-24 hour culture for 3-4 seconds.[0212]3.2 Make two 1 / 100 dilutions in sterile PBDW and on final dilution of 5.0 mL of diluted c...

Residual Self-Sanitizing Screen of Test Composition C
[0259]The objective of the analysis was to examine the residual self-sanitizing efficacy of Test composition C (a composition according to the invention) against Staphylococcus aureus ATCC 6538 and Klebsiella pneumoniae ATCC 4352 after application to inanimate, non-porous, non-food contact surfaces.
Test Method:
Residual Self-Sanitizing Activity on Hard, Non-Porous Surfaces
Test System Preparation
[0260]1. At least three consecutive loop transfers of a 24 hour culture of Staphylococcus aureus ATCC 6538 and Klebsiella pneumoniae ATCC 4352 were performed in 10 mL of AOAC Synthetic broth or AOAC Nutrient broth (respectively) and incubated at 35° C.[0261]2. Initial Inoculum Suspension:
[0262]2.1 Vortex a 48-54 hour culture for 3-4 seconds.
[0263]2.2 Make two 1 / 100 dilutions in sterile PBDW and let stand for 15±1 minutes.[0264]3. Reinoculation Suspension:[0265]3.1 Vortex an 18-24 hour culture for 3-4 seconds.[0266]3.2 Make two 1 / 100 dilution...
