PERFORMANCE
The advantage of polonium chloride over other commonly used antibacterial agents is that it is often compared to benzalkonium chloride. In the antibacterial efficacy tests against five bacterial strains, including Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Candida albicans, and Aspergillus niger, the two have comparable antibacterial effects. However, polonium chloride is a hydrophilic cationic polymer with a molecular size about 27 times that of benzalkonium chloride. Its large molecular weight prevents it from entering mammalian cells, making it less toxic and less toxic, mild, and effective.

Polyammonium chloride, as a new type of quaternary ammonium salt antibacterial agent, has the characteristics of strong antibacterial effect, light toxic side effects, and low usage concentration. It is used as an ophthalmic antibacterial agent and has no toxicity to the cornea, without affecting the normal growth of corneal epithelial cells. It is an ideal ophthalmic antibacterial agent. Compared to other eye drops used as antibacterial agents, it has the advantages of a wide antibacterial spectrum, better safety, and lower usage concentration
