PHMB thiab polyaminopropyl biguanide yog hom biguanides thiab yog chlorhexidine derivatives. Cov txheej txheem ib txwm ua ntawm cov kab mob bactericidal biguanides yog los cuam tshuam cov plasma daim nyias nyias ntawm cov kab mob ntawm tes thiab tshem tawm cov kev ua haujlwm metabolic hauv lub cell (Gromacki thiab Ward, 2013).
Poly (hexamethylene Biguanide) Hydrochloridenyob rau hauv kev sib cuag lens daws yog ib tug dav siv preservative thiab tshuaj tua kab mob. Nws yog cationic polymer uas cuam tshuam cov kab mob ntawm cov kab mob, nrog rau cov kab mob, kab mob, thiab Acanthamoeba, ua rau nws zoo rau kev ntxuav thiab tua kab mob lo ntsiab muag. PHMB muaj nyob rau hauv ntau hom kev daws teeb meem los tiv thaiv cov kab mob microbial thiab tswj kom tsis muaj menyuam ntawm cov lo ntsiab muag thaum khaws cia.
