Benzalkonium Chloride (BKC) 80%

Molecular Weight: 340.0

CAS No.: 63449-41-2, 8001-54-5

Molecular Formula: C21H38NCl


BKC 80% is the short name of Benzalkonium chloride 80. It is a kind of quaternary ammonium-based nonoxidizing biocide. It belongs to cationic surfactants.

BKC 80% has excellent properties of dispersing and penetrating. It can easily penetrate and remove sludge and algae in water flooding for EOR(enhanced oil recovery).

Benzalkonium chloride has advantages of low toxicity, no toxicity accumulation. And it is also soluble in water. The BKC 80% is so convenient to use and unaffected by water hardness. BKC 80 can be also used as an anti-mildew agent, antistatic agent, emulsifying agent, and amendment agent in woven and dyeing fields.

BKC 80% is widely used in many fields because 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, BKC 80% can prevent algae growth, bacterias development, and also sludge reproduction.

BKC 80% can also be used in the formulation of pipeline corrosion inhibitors, sludge breakers, and de-emulsifiers for the enhanced oil process of recovery.

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.
