Product Introduction:

The average molecular weight of polyhexamethylene biguanide hydrochloride is 1100-1800, and the molecular formula is (C8H17N5)n·xHCl, n=12-16. Polyhexamethylene biguanide hydrochloride (PHMB) is a broad-spectrum antibiotic that can kill gram-positive, gram-negative, mold and yeast.

PHMB sterilization principle:

The guanidine group of PHMB has high activity, so it can make polymers positively charged, and it is easily adsorbed to various negatively charged bacteria and viruses, inhibiting the division of bacteria and viruses, causing them to lose the division function of bacteria and viruses.

The membrane formed by the fertility polymer blocks the microbes’ breathing passages, causing the microbes to suffocate and die quickly.

PHMB bactericidal effect:

  • Acts quickly on bacteria and viruses
  • Acts on Gram-positive and Gram-negative bacteria
  • Acts on pathogens (eg E. coli 0157:H7)
  • Acts on antibiotic-resistant bacteria
  • Acts on envelopes and naked viruses

Physical and chemical properties:

Polyhexamethylene biguanide hydrochloride solution is a colorless or pale yellow transparent liquid. The guanidine group in it has high activity, so it can make polymers positively charged.

Since they are easily negatively charged by various bacteria, they are adsorbed to viruses, preventing the division of bacteria and viruses. It suppresses fertility, and the membrane formed by polymer blocks the microorganism’s respiratory tract, causing the microorganism to die quickly.


  1. used for wet wipes
    The antibacterial effect is mainly by dissolving lipids and changing the permeability of bacterial cell membranes, thereby interfering with bacterial metabolism and antibacterial.
