Polyhamethylene guanidine hydrochloride (PHGC) is a broad-spectrum fungicide and also an environmentally friendly, multi-purpose new cationic polymer. It is highly soluble in water, and its aqueous solution is colorless and odorless. It has many excellent properties such as broad-spectrum high efficiency, low usage concentration, no foaming, no drug resistance, and biodegradability. It has been widely applied in the sterilization and mold prevention of plant protection, medicine, industrial products, food and daily necessities. Its bactericidal mechanism is as follows: The guanidine group has high activity, making the polymer positively charged and easily adsorbed by various bacteria and viruses that are usually negatively charged, thereby inhibiting the division function of bacteria and viruses and causing them to lose their reproductive ability. Meanwhile, it is a high-molecular polymer that can form a film to block the respiratory channels of microorganisms, causing them to suffocate and die rapidly. Polyhexamethylene guanidine hydrochloride is an ophthalmic compound containing phenylephrine. Polyhamethylene guanidine hydrochloride is an antibacterial agent. A preparation method for multifunctional flame-retardant polyester fabrics.
Its high-molecular polymer structure reduces its toxicity. However, its sterilization effect is even more outstanding and it has been widely applied in various fields such as medical and health institutions, family life, food industry and livestock breeding.
The guanidine group of polyhamethylene guanidine hydrochloride has high activity, making the polymer positively charged. Therefore, it is easily adsorbed by various bacteria and viruses that are usually negatively charged, thereby inhibiting the division function of bacteria and viruses and causing them to lose their reproductive ability. In addition, the film formed by the polymer blocks the respiratory channels of microorganisms. Cause microorganisms to suffocate and die rapidly.
