1) PHMB is recognized as the safest and the most efficient broad-spectrum antibacterial agent in the 21st century. 2) PHMB 20% is colorless and tasteless; 3) Low bacterial inhibition concentration, broad spectrum, low toxicity. 4) No bacteria drug resistance.

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.

PHMB is a new kind of multi-purpose bactericidal and bacteriostatic polymer. The chemical name is Poly(hexamethylenebiguanide) hydrochloride, CAS # 32286-58-0. And the main purity is 98% powder, 95% powder, or 20% solution.
