List of Biocidal active substances

The following is the original English text.
A seguir, o texto original em inglês.

PHMG is a cationic polymer that is positively charged and is a cell membrane active antimicrobial agent, and biocidal active substance.

Antibacterial mechanism:
PHMG Guanidine polymer has strong adsorption power to negatively charged fungi, bacteria and viruses, thus inhibiting the division function of bacteria and disabling the reproductive ability of bacteria and viruses. At the same time, PHMG will form a film to block the respiratory channels of pathogens, so that the pathogens suffocate and die quickly.

Broad spectrum bactericide;
Fast action speed;
Long-term bacterial inhibition;
Stable nature;
Easily soluble in water;
Can be used at room temperature;
Can be used at low concentration.

Fields of application:
PHMG chloride is a cationic polymer, antimicrobial agent, biocide, bactericide, disinfectant, anti-mould, anti-slime, anti-biofilm, non-oxidizing biocides for cooling water treatment, etc.
It is widely used in non-oxidising biocide, cooling tower, oilfield chemicals, textile printing and dyeing, swimming pool disinfection, flower antiseptic treatment, etc.

Dilute directly with purified water or use with other additives. Reference dosage 0.05%~0.5% (w/w).
PHMG should not be mixed with anionic surfactants, and the actual use concentration should be determined by the season, environment, concentration of microorganisms and other factors.

Store at room temperature away from light, airtight and protected from moisture.
