Structure Formula:


Benzalkonium chloride is a kind of cationic surfactant belonging to the nonoxidizing biocide. Therefore, it can efficiently withhold algae propagation and sludge reproduction.

Benzalkonium chloride also has to disperse and penetrating properties, can penetrate and remove sludge and algae, and has the advantages of low toxicity, no toxicity accumulation, soluble in water, convenient use, and unaffected by water hardness.

Benzalkonium chloride can also be used as an anti-mildew, antistatic, emulsifying, and amendment agent in woven and dyeing fields.

As a nonoxidizing biocide, 50~100mg/L is preferred; as sludge remover, 200~300mg/L is preferred. An adequate organosilyl antifoaming agent should be added for this purpose.

Benzalkonium chloride can be used with other fungicides, such as isothiazolinones, glutaraldehyde, dithionitrile methane, for synergism but cannot be used together with chlorophenols.

Suppose sewage appears after throwing this product in circulating cool water. In that case, the sewage should be filtered or blown off in time to prevent their deposit in the bottom of the collecting tank after froth disappearance.

No blending with anion surfactant.
