El clorhidrato de PHMB, un agente antimicrobiano cati\u00f3nico de amplio espectro, consigue la esterilizaci\u00f3n inhibiendo la actividad de la membrana celular.<\/p>\n\n\n\n

Como agente antimicrobiano activo de la membrana celular, el PHMB inhibe la actividad bacteriana mejor que la de los hongos, y su mecanismo antimicrobiano es aproximadamente el siguiente:
El PHMB es un compuesto cati\u00f3nico polimerizado, que es f\u00e1cilmente adsorbido por varios tipos de bacterias que suelen estar cargadas negativamente, inhibiendo as\u00ed la funci\u00f3n de divisi\u00f3n de las bacterias y haciendo que \u00e9stas pierdan su capacidad reproductiva.<\/p>\n\n\n\n

Poly(hexamethylenebiguanide) hydrochloride PHMB, a cationic broad-spectrum antimicrobial agent, achieves bactericidal purpose by inhibiting cell membrane activity.<\/p>\n\n\n\n

As a cell membrane active antimicrobial agent, PHMB inhibits bacterial activity better than that of fungi, and its antimicrobial mechanism is roughly as follows:
PHMB is a polymerized cationic compound, which is easily adsorbed by various types of bacteria that are usually negatively charged, thus inhibiting the division function of the bacteria and making the bacteria lose the ability to reproduce.<\/p>\n\n\n\n

Features:
<\/strong>1. HPMB has the ability to inhibit Gram-positive bacteria, Gram-negative bacteria, fungi (many kinds of ringworm and mold) and yeast.
2. PHMB has rapid inhibitory effect on E. coli, Staphylococcus aureus and Candida albicans.
3. PHMB: LD50\uff1e5000mg\/kg, HPMB is skin friendly, human and environment friendly.<\/p>\n\n\n\n
