Polyhexamethyleneguanidine hydrochloride (PHMG) is a broad-spectrum fungicide and an environmentally-friendly, multi-purpose new cationic polymer. It is easily soluble in water. The aqueous solution is colorless and odorless. It has a broad-spectrum high efficiency, low use concentration, and no Many excellent properties, such as foam, no drug resistance, and biodegradability, have been widely used in plant protection, medicine, industrial products, food and daily sterilization and mildew prevention.
Polyhexamethylene guanidine (PHMG) has biguanide salts and monoguanidine salts, such as polyhexamethylene biguanide hydrochloride and polyhexamethyleneguanidine hydrochloride and its derivatives as a new generation of guanidine disinfectants has been widely used . Its sterilization mechanism is: guanidine group has high activity, which makes the polymer positively charged and easily adsorbed by various types of bacteria and viruses that are usually negatively charged, thereby inhibiting the splitting function of bacterial viruses and causing bacterial viruses to lose their reproductive ability. At the same time, it is a high-molecular polymer, which can form a film to block the breathing channels of microorganisms, so that the microorganisms quickly suffocate and die.
