[ Performance and Features ]
1. Kill and inhibit various microorganisms with high efficiency and broad spectrum.
2. Bacteria do not develop drug resistance.
3. There is no toxicity to human body and higher animals in the concentration.
4. Colorless and odorless without irritation to skin and mucous membrane.
5. No corrosion to the treated surface.

[ Antimicrobial Principle ]
1. Broad spectrum of sterilization; low effective concentration; fast action speed; stable properties; excellent performance of being easily soluble in water; can be used at room temperature.
2. Long-term antibacterial effect: colorless, odorless; safe to use.
3. Long-term effect: Since polyhexamethylene guanidine is a stable polymer, it does not volatilize or decompose, so it can be stored for a long time, and after the polyhexamethylene guanidine solution is dried, it can form a disinfectant on the surface of the object. The thin polymer layer of the agent can keep the object in good condition after sterilization, and at the same time prevent the object from secondary pollution.
4. Safety: Since polyhexamethylene guanidine is a high molecular polymer, it is not easy to be absorbed by animal tissues, so that polyhexamethylene guanidine has basically no effect on the cells of higher organisms. In addition, experiments have proved that polyhexamethylene guanidine can be degraded naturally and will not cause pollution to the environment.
5. Mild to the skin

About Polyhexamethylene Guanidine (PHMG)
Polyhexamethylene Guanidine (PHMG) has a strong ability to kill bacteria and viruses, and has a broad spectrum and high efficiency, and has a long-term antibacterial effect. Since the guanidinium group of PHMG has high activity, the polymer is positively charged, so it is easily adsorbed by various negatively charged bacteria and viruses, thereby inhibiting bacteria and viruses. The division function of bacteria and viruses loses their reproductive ability. In addition, the film formed by the polymer blocks the respiratory channels of the microorganisms, causing the microorganisms to suffocate quickly > At the same time, because PHMG is a polymer structure, the effective activity of the guanidine group can be improved , so the bactericidal effect of PHMG is much higher than that of other guanidine compounds.
