  1. Application

Polyhexamethylene biguanide (PHMB) is a kind of broad-spectrum antibacterial agent recognized as the safest and most efficient in the 21st century. It is colorless and odorless, has low bacteriostatic concentration, broad-spectrum and low toxicity, fast action, low foam volume, and can After forming a layer of cations on the surface of the article for a long time, it will not cause bacteriostasis, and it will not cause antibacterial bacteria. It is currently widely used in medical devices, public environments, home, fabrics, food, milk, and care products. .

Polyhexamethylene biguanide (PHMB) is widely used in medical and health, daily chemicals, textiles, paper, wet wipes, animal husbandry, breeding, aquatic products, plastics, agriculture, water treatment and other fields
