As a biologically active organic base, guanidine-based polymers are widely used in medicine, agriculture, textile, and other fields.
PHMB has been widely used in various medical and non-medical applications, including wound care products, contact lens solutions, and disinfectants. PHMB has found numerous applications in wound care due to its excellent antimicrobial activity against a wide range of bacteria, fungi, and some viruses.
Advantages of Polyhexamethylene Bisoguanide Hydrochloride
1. Excellent bactericidal ability
PHMB is a broad-spectrum fungicide that has good efficacy against Gram-negative bacteria that are difficult to treat with general fungicides and can also achieve good bactericidal effects at low concentrations without making bacteria resistant to resistance.
The sterilization speed is fast. After sterilization, the PHMB cation is adsorbed on the surface of the article, so the growth of bacteria can be inhibited for a long time.
2. Good stability
Non-volatile, good water solubility, insensitive to temperature and light, easy to store and transport.
3. Other Characteristics
No toxic and side effects (PHMB itself is a high molecular polymer, not easily absorbed by body tissues), basically non-corrosive, low foam, easy to rinse, etc. In addition, compared with iodophor and other disinfectants, PHMB also has the advantage of not staining.
