Molecular formula:


Antibacterial principle:

Guanidine group has high activity, can make the polymer become positively charged, it is easy to be adsorbed by all kinds of bacteria and viruses that are negatively charged, thereby inhibiting the division function of bacteria and viruses, causing them to lose their reproductive ability. Another active ingredient, hydrochloric acid, enhances the bactericidal ability.

PHMG performance advantages

(1) PHMG is stable properties, excellent performance of being easily soluble in water; can be used at room temperature; With feature of low effective concentration; fast action speed. It has no side effects; non-corrosive; colorless and odorless; non-flammable and non-explosive, safe to use;

(2) Polyhexamethylene guanidine is a stable polymer, it is not volatile and does not decompose; Be stored for a long time, and after the polyhexamethylene guanidine solution is dried, it can form a The thin polymer layer of the disinfectant can maintain the best state of the object after sterilization and prevent secondary pollution of the object.

(3) Non-toxicity: Because it is a high molecular polymer, it is not easily absorbed by animal tissues, which greatly reduces the toxicity of polyhexamethylene guanidine and makes polyhexamethylene guanidine effective in higher organisms. The cells have basically no effect. In addition, experiments have proved that polyhexamethylene guanidine can be degraded naturally and will not cause pollution to the environment.

(4) It has no skin irritation: Shanghai Municipal Center for Disease Control conducted an experimental study of polyhexamethylene guanidine on skin with rabbits. The conclusion is that a 0.2% solution has an integral value of 0 for skin irritation and no skin irritation. (Judgment criteria: the lower the integral value, the lower the irritation.)


Directly dilute with purified water or use in combination with other additives. The reference dosage is 0.05%~0.5%(w/w).


It is effective against Escherichia coli, Staphylococcus aureus, Candida albicans, Neisseria gonorrhoeae, Salmonella, Pseudomonas aeruginosa, Listeria, Shigella, Aspergillus niger, Brucella, Para Vibrio hemolyticus, Vibrio alginolyticus, Vibrio anguillarum, Aeromonas hydrophila, sulfate-reducing bacteria, iron bacteria, and saprophytes have a complete killing effect. It is suitable for sterilization, disinfection and algae elimination in industries such as skin, mucous membranes, fruits and vegetables, air, drinking water, swimming pools, general surfaces, papermaking, toilet paper, women’s sanitary napkins, clothing and aquaculture, animal husbandry, and tertiary oil extraction.

Package: 25kg/drum, 50kg/drum, 100kg/drum.
