Benzalkonium Chloride, DDBAC


Benzalkonium chloride is a kind of cationic surfactant. It is also called DDBAC or BKC 1227. Benzalkonium chloride belongs to the nonoxidizing biocide. DDBAC can efficiently withhold algae propagation and sludge reproduction.

Benzalkonium Chloride also has to disperse and penetrating properties. BKC 1227 can penetrate and remove sludge and algae. It has advantages of low toxicity, no toxicity accumulation, soluble in water, convenient in use, unaffected by water hardness.

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

As nonoxidizing biocide, the dosage of 50-100 mg/l is preferred. As sludge remover, 200-300 mg/l is preferred. An adequate organosilyl antifoaming agent should be added for this purpose.

DDBAC can be used together with other fungicidal. Such as isothiazolinones, glutaraldehyde, dithionitrile methane for synergism. But benzalkonium chloride cannot be used together with chlorophenols.

If sewage has appeared after thrown of this product in circulating cool water, the sewage should be filtered or blown off in time. That can prevent their deposit in the bottom of collecting tank after froth disappearance. No blending with anion surfactant.
