Performance and advantages

① Keywords broad spectrum of sterilization; low effective concentration; fast acting speed; stable property; excellent performance of water soluble; can be used at room temperature;

② It has the advantages of long-term bacteriostasis, no side effect, no corrosiveness, colorless and odorless, non flammable and non explosive, safe to use;

③ Long term effect: as polyhexamethylene guanidine is a stable polymer, which is not volatile and does not decompose, it can be stored for a long time. After drying, the polyhexamethylene guanidine solution can form a thin layer of disinfectant polymer on the surface of the object, which can keep the object in good condition after sterilization and prevent the object from secondary pollution. In general, the various surfaces treated with polyhexamethylene guanidine aqueous solution will remain sterile for up to three months.

④ Nontoxicity: as polyhexamethylene guanidine is a high molecular polymer, it is not easy to be absorbed by animal tissues, which greatly reduces the toxicity of polyhexamethylene guanidine, so that polyhexamethylene guanidine has no effect on the cells of higher organisms. In addition, the experiment proved that polyhexamethylene guanidine can be naturally degraded and will not cause pollution to the environment.

⑤ No skin irritation: the experimental study of polyhexamethylene guanidine on skin was carried out in rabbits by Shanghai Center for Disease Control and prevention. Conclusion: 0.2% solution, skin irritation response integral value is 0, no skin irritation. (judgment criteria: the lower the integral value, the lower the irritation.
