Antibacterial mechanism
PHMG Guanidine polymer has strong adsorption power to negatively charged fungi, bacteria and viruses, thus inhibiting the division function of bacteria and disabling the reproductive ability of bacteria and viruses. At the same time, PHMG will form a film to block the respiratory channels of pathogens, so that the pathogens suffocate and die quickly.
