Polyhexamethyleneguanidine Hydrochloride CAS 57028-96-3

CAS 57028-96-3
MF: C7H22ClN5
MW: 211.74
CAS: 57028-96-3


Polyhexamethylene hydrochloride property


Polyhexamethylene guanidine has a strong ability to kill bacteria, has no etching effect on various materials, is non corrosive, and does not contain harmful substances such as aldehyde, iodine, and active chlorine.


Sterilization principle:


The guanidine group of Polyhexamethylene guanidine has high activity, which makes the polymer positively charged, so it is easy to be absorbed by various bacteria and viruses that are usually negatively charged, thus inhibiting the division function of bacteria and viruses, making bacteria and viruses lose their reproductive capacity. In addition, the film formed by the polymer blocks the respiratory channel of microorganisms, causing rapid suffocation of microorganisms.

Appearance Polyhexamethylene guanidine is a colorless to yellowish solution after being dissolved in water.
