Introduction of polyhexamethyleneguanidine hydrochloride (PHMG)
Polyhexamethyleneguanidine is a new type of safe and non-toxic cationic fungicide, referred to as PHMG, which has many derivatives, such as hydrochloride, phosphate and propionate, etc. It is currently the most commercialized and widely used.
The most important is polyhexamethyleneguanidine hydrochloride, which is what we call monoguanidine. The guanidine group in PHMG has high activity, which makes the polymer positively charged, so it is easily adsorbed by various bacteria and viruses that are usually negatively charged, thereby inhibiting the division function of bacteria and viruses, and making bacteria and viruses lose reproductive capacity.
The film formed by the polymer blocks the respiratory passage of microorganisms, causing the
microorganisms to suffocate quickly. After the polyhexamethyleneguanidine hydrochloride (PHMG) solution is dried, a thin layer of polymer can be formed on the surface of the object to be treated, which can isolate bacteria and viruses in the air, maintain the sterilized state of the object, and prevent the secondary contamination of the object at the same time. secondary pollution. In general, the surface of an object treated with polyhexamethyleneguanidine hydrochloride (PHMG) will remain sterile for about three months.
Polyhexamethyleneguanidine hydrochloride (PHMG) has inhibitory and killing effects on various bacteria
and viruses, such as Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, etc. It is a safe and non-toxic broad-spectrum Fungicides are widely used in many industries and fields such as medical and sanitation, water treatment, wet wipes, papermaking, textiles, agriculture, forestry, animal husbandry and fishery, plastics, coatings, and daily chemicals.
