Product Instruction: 
Polyhsamethylmonoguanidine hydrochloride is a broad-spectrum fungicide and a new type of environment-friendly multi-purpose cationic polymer. It is easily soluble in water, and its aqueous solution is colorless and odorless. It has many excellent properties, such as broad-spectrum high efficiency, low concentration, no foam, no resistance, biodegradable, etc. It has been widely used in plant protection, medicine, industrial products, food and daily use.


Mechanism of action:
The guanidine group has high activity, which makes the polymer positive electric, easy to be adsorbed by all kinds of bacteria and viruses which are usually negative, thus inhibiting the division function of bacterial viruses and making bacterial viruses lose the ability to reproduce. At the same time, it is a polymer, can form a film to block the microbial breathing channels, so that microorganisms quickly suffocate to death.


Product Usage:
Polyhexamethylmonoguanidine hydrochloride is an ophthalmic compound containing phenylephrine; It is an antibacterial agent used in the preparation of multifunctional flame retardant polyester fabric. Its high polymer structure makes it less toxic. But the sterilization effect is more excellent, has been widely used in medical and health institutions, family life, food industry and animal husbandry and other fields.




Application method:
Dilute directly with purified water or use with other additives. Reference dosage 0.05%-0.5% (w/w). It should not be mixed with anionic surfactants. The actual use concentration should be determined by the season, environment, microbial concentration in the raw material and other factors.


Characteristics & Advantages:
①Bactericidal broad spectrum; Low effective concentration; Fast acting speed; Stable in nature; Easy to dissolve in water; Can be used at room temperature;
②Long-term bacteriostasis, no side effects; Non-corrosive; Colorless, odorless; Non-combustible, non-explosive, safe to use;
③Long-term performance: As a stable polymer, it does not volatilize or decompose, so it can be stored for a long time. Besides, after the solution is dried, it can form a polymer thin layer of disinfectant on the surface of the object, which can keep the object in a good state after sterilization and prevent secondary pollution of the object. Generally, surfaces treated with an aqueous solution of polyhexamethylguanidine will remain sterile for up to three months.
④Safety: Due to the fact that polyhsamethylguanidine is a polymer, it is not easy to be absorbed by animal tissues, which greatly reduces the toxicity of polyhsamethylguanidine, so that polyhsamethylguanidine has no effect on the cells of higher organisms. In addition, the experiment proved that poly (hexamethylguanidine) can be degraded naturally and will not cause pollution to the environment.
⑤No irritation to skin: The Shanghai Center for Disease Control conducted an experimental study of polyhexamethylguanidine on skin with rabbits. Conclusion: 0.2% solution, skin irritation response integral value is 0, no skin irritation. (Judging criteria: the lower the score, the lower the incentive)


Package & Storage:
Packed by drums 
Keep at room temperature away from light, sealed and moisture-proof.
