Table 1 Reduction of viral infectivity (log10 steps) obtained with three alcohol-based hand rubs (A: based on 45% isopropanol, 30% n-propanol and 0.2% mecetronium etilsulfate; B: based on 80% ethanol; C: based on 95% ethanol) against the six different enveloped viruses with different types of organic load.

From: Suitability of vaccinia virus and bovine viral diarrhea virus (BVDV) for determining activities of three commonly-used alcohol-based hand rubs against enveloped viruses
