Dodecyl Dimethyl Benzyl ammonium Chloride 1227


Benzalkonium Chloride is a kind of cationic surfactant, belonging to nonoxidizing biocide. It can efficiently withhold algae propagation and sludge reproduction. Benzalkonium Chloride also has dispersing and penetrating properties, can penetrate and remove sludge and algae, has advantages of low toxicity, no toxicity accumulation, soluble in water, convenient in use, unaffected by water hardness. Benzalkonium Chloride can be also used as anti-mildew agent, antistatic agent, emulsifying agent and amendment agent in woven and dyeing fields.


Appearance Colorless to yellowish transparent liquid Yellowish transparent liquid
Active content 48%~52% 78%~82%
Amine salt  ≤2.0% ≤1.0%
pH 6.0~8.0(as it) 6.0-8.0 (1% water solution)
Flowability normal  Good fluidity


As nonoxidizingbiocide, dosage of 50-100mg/L is preferred; as sludge remover, 200-300mg/L is preferred, adequate organosilyl antifoaming agent should be added for this purpose. This productcan be used together with other fungicidal such as isothiazolinones, glutaraldegyde, dithionitrile methane for synergism, but cannot be used together with chlorophenols. If sewage is appeared after thrown of this product in circulating cool water, the sewage should be filtered or blown off in time to prevent their deposit in bottom of collecting tank after anion disappearance.

No blending with anion surfactant.
