Dubious and potentially DANGEROUS claims questioned by some researchers., page-24

Apparently studies found that a lower concentration of Benzalkonium Chloride is more effective on the human coronavirus. qoute "Data obtained with benzalkonium chloride at reasonable contact times were conflicting. Within 10 min a concentration of 0.2% revealed no efficacy against coronavirus whereas a concentration of 0.05% was more effective" . The makers of Purell funds the CDC so bias and politics as usual is always involved. you report table ll is so obviously skewed to favour ethanol. I was surprised it did not indicate at what concentration the Benzalkonium Chloride checmical used is effective as indicated by the rest of the findings. but instead only reported the concentration it was not effective. lol. anyone can infer the report is heavily biased.
