What is biocide polyhexamethylene biguanide? Polyhexamethylenebiguanide is a new international safe and non-toxic polymeric guanidine bactericide. The methylguanidine in its derivative polyhexamethyleneguanidine hydrochloride has high activity itself. This activity can make the polymer is positively charged and easily adsorbed by bacteria and viruses. Thus, it inhibits the division function of bacteria and viruses and disables them to reproduce. Moreover, the formation of the polymer blocks the respiratory channels of microorganisms and suffocates them to death.

In addition, polyhexamethylene biguanide also has the following characteristics.

1、It is easily soluble in water ;

2、Aqueous solution is non-toxic, colorless and odorless;

3、Non-combustible, non-explosive;

4, has a strong ability to kill bacteria, and broad-spectrum, high efficiency, and has a long-term antibacterial effect;

5、No leaching effect on various materials;

6、No corrosion;

7, does not contain aldehyde, iodine, active chlorine and other harmful substances.

Because of its excellent characteristics, polyhexamethylene biguanide has been widely used in home disinfection, skin disinfection, public places sterilization and purification agent, hand disinfectant and other products and fields. Some companies have even compounded polyhexamethylene biguanide with bioenzyme to produce bioenzyme products with disinfection, antibacterial and purification functions.

During the prevention and control of COVID-19, human hands are constantly exposed to items contaminated with viruses and bacteria. Especially, doctors and nurses in hospitals have more chances to come into contact with them. Therefore keeping hands clean and hygienic is one of the effective ways to reduce the risk of contracting novel coronavirus.

The main feature of polyhexamethyleneguanidine disinfectant is that it is effective in sterilization and can quickly kill many kinds of bacteria. The bactericidal rate is up to 99.999%. No drug resistance, safe and non-toxic. Tested by authoritative inspection department, the result is actual non-toxic level, mild and non-irritating, no stimulation to human body, no pollution to the environment and no corrosion to objects.

In the prevention and control of COVID-19, it played a major role in the daily hand and object surface disinfection mainly in hospitals and home personnel. The advantages of application especially in large trauma surfaces of mucous membranes and wounds are irreplaceable by alcohol-based disinfection products. The improved product enhances the bactericidal effect of polyhexamethylene guanidine through bioenzyme, and also has the characteristics of bioenzyme deodorization and deodorization and long-lasting bacterial inhibition.
