IISpecification

III. Performance Features
    1. Efficient broad-spectrum killing and inhibition of all kinds of microorganisms.
    2. No Bacteria drug resistance.
    3. Non-toxic to human being under using concentration
    4. Colorless, odorless, non-irritating to skins and mucosae
    5. No corrosion to the treated surface.
IV. Antibacterial Mechanism
    Guanidyl in PHMG has very high activity, which makes polymer electropositive, so PHMG is very easily adsorbed by all kinds of bacteria and viruses which are generally electronegative, inhibiting the fission of them and making them lose reproductive capacity. The film formed by the polymer blocks the breathing channel of microorganisms, and makes them quickly suffocated.
V. Incompatibility
    The product is a cationic bactericide, it cannot be compatible with anionic bactericides or acids, otherwise, its bactericidal activity would be greatly reduced.
VI.Heat stability
    The product has the validity period of 2 years when stored at 37℃, and the validity period of 1 year when stored at 54℃.
VII.Influence of pH value
    The bactericidal effect of PHMG can be improved under the alkaline condition, while its bactericidal effect can be reduced under the acidic condition. It is used at the pH of 5.5-9.5.
VIII.Influence of organic matters
    The organic matters can reduce the bactericidal effect of PHMG. Tests proved that bacterial suspension containing 25% of calf serum cannot influence the staphylococcus aureus killing effect of diluent; and bacterial suspension containing 50% of calf serum has moderate influence on the staphylococcus aureus killing effect of diluent.
