Aims: The objective of this study was to evaluate virucidal efficacy of the commercially available povidone-iodine formulations Betaisodona® solution and Betaseptic Mundipharma® (Mundipharma).
Methods and Results: The quantitative suspension test for virucidal testing of biocides according to the German guideline was used as method. The use of Betaisodona® solution resulted in virucidal efficacy, corresponding to ≥104-fold reduction in viral titre, against vaccinia virus, bovine viral diarrhoea virus and polyomavirus SV40 within 0·5 min and adenovirus type 5 within 3–5 min without and with organic load. For inactivation of the most resistant poliovirus type 1, a time interval of ≥60 min was needed. By contrast, Betaseptic Mundipharma® inactivated significantly all model viruses for virucidal testing including poliovirus type 1 within 5 min independently from the addition of proteins.
Conclusions: Betaisodona® solution shows a good efficacy against enveloped model viruses as well as against some nonenveloped human viruses, e.g. adenovirus and polyomavirus. Betaseptic Mundipharma® has an excellent virucidal efficacy including the inactivation of the most resistent poliovirus type 1.
Significance and Impact of the Study: The findings of this study make Betaseptic Mundipharma® suitable for virucidal disinfection of the skin within short time intervals.
