The antibacterial effect of PHMB 20% is characterized by high efficiency, safety, stability, long-term effect, convenient use and environment friendly. It has the ability to kill bacteria, fungi, algae and yeast. It acts on the cell wall or cell membrane of bacteria, fungi, algae.

Polyhexamethylene biguanide, also known as PHMB, polyhexanide or polihexanide, is a highly water soluble and hydrolytically stable polymeric material. Used in cosmetics, personal care products, fabric softeners, contactlens solutions, hand washes, and more.

PHMB is a new kind of multi-purpose bactericidal and bacteriostatic polymer. Its hydrophilic part contains strong positive electricity. It can absorb all kinds of bacteria and viruses which are usually negative electricity, enter into the cell membrane, inhibit the synthesis of liposomes in the membrane, cause the cell to die, and achieve the best bactericidal effect.
