Polyhexamethylene guanidine- feem ntau ntsib nyob rau hauv daim ntawv ntawm polyhexamethylene guanidine hydrochloride (PHMG los yog PHMB)- yog ib tug polymeric biocide dav siv nyob rau hauv teb xws li tshuaj tua kab mob thiab tshuaj tua kab mob. Nws nthuav tawm dav -spectrum antimicrobial kev ua haujlwm, muaj txiaj ntsig zoo tiv thaiv ntau yam kab mob thiab cov fungi. Nws cov txheej txheem ntawm kev txiav txim yog predicated rau cov kev ua ntawm nws cov pab pawg neeg guanidine, uas impart ib tug zoo nqi rau lub polymer; Qhov kev them nqi zoo no txhawb nqa cov kab mob adsorption- uas feem ntau muaj cov nqi tsis zoo- yog li inhibiting lawv cov cellular faib.
Cov kev tshawb fawb txog tshuaj toxicological qhia tau hais tias qhov mob qhov ncauj LD50 hauv cov nas tshaj 5000 mg / kg, faib cov tshuaj raws li kev xyaum tsis yog- tshuaj lom, thiab nws tsis pom muaj kev cuam tshuam rau ntawm daim tawv nqaij. Txawm li cas los xij, kev tshawb fawb simulating qhov nqus tau pa tau qhia tias kev raug mob rau PHMG tuaj yeem ua rau muaj kev pheej hmoo ntawm kev ua pa lom.
