In order to design a QAC with enhanced antimicrobial
properties, we developed ethoxylated version of the QAC, called
K21, which was tested effective against Porphyromonas gingivalis
and Enterococcus faecalis (Meghil et al., 2015). With an intention of
using K21 in dental materials, we tested efficacy of K21 against
some of the human herpes viruses including HSV-1, HHV-6A, HHV-
6B and HHV-7 that reside in the human oral cavities and are shed in
the saliva to induce infection.
