Properties

DDBAC is the short name of dodecyl dimethyl benzyl ammonium chloride. The chemical formula is C21H38NCl. It is a kind of quaternary ammonium-based nonoxidizing biocide. It belongs to cationic surfactants. It is the same biocide as benzalkonium chloride.

DDBAC is widely used in many fields because of it can efficiently control bacteria, algae, and fungi and envelop viruses at exceptionally low ppm concentrations. Such as food, water treatment, cosmetics, pharmaceuticals, livestock, detergent, aquaculture, household and hospital industries.

In the oil and gas industry, dodecyl dimethyl benzyl ammonium chloride can prevent algae growth, bacterias development, and also sludge reproduction.

At the same time, DDBAC has excellent properties of dispersing and penetrating. It can easily penetrate and remove sludge and algae in water flooding for EOR(enhanced oil recovery).

DDBAC can also be used in the formulation of pipeline corrosion inhibitors, sludge breakers, and de-emulsifiers for the enhanced oil process of recovery.

Dodecyl dimethyl benzyl ammonium chloride has advantages of low toxicity, no toxicity accumulation. And it also soluble in water. The DDBAC is so convenient to use and unaffected by water hardness. DDBAC can be also used as an anti-mildew agent, antistatic agent, emulsifying agent and amendment agent in woven and dyeing fields.

IRO Biocide is among the best dodecyl dimethyl benzyl ammonium chloride manufacturers and suppliers of dodecyl dimethyl benzyl ammonium chloride (DDBAC) for oilfield water treatment. We always supply high-quality DDBAC products.

Dodecyl dimethyl benzyl ammonium chloride can efficiently withhold algae propagation and sludge reproduction. Benzalkonium chloride also has dispersing and penetrating properties. It can penetrate and remove sludge and algae. DDBAC 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.

Applications

what is dodecyl dimethyl benzyl ammonium chloride used for?

As nonoxidizing biocide, the 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.

DDBAC can be used together with other fungicidal. Such as isothiazolinones, glutaraldehyde, dithionitrile methane for synergism, but 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 to prevent their deposit in the bottom of collecting tank after anion disappearance.

No blending with anion surfactant.

Package and Storage
