Benzalkonium chloride solution (also Benzalkoniumchloride, Benzalkonium chlorid) is a kind of quaternary ammonium based nonoxidizing biocide which belongs to cationic surfactants. As benzalkonium chloride disinfectant can efficiently withhold algae, bacteria and fungi and envelop viruses at exceptionally low ppm concentrations, it is widely used as a biocide in many industries such as food, water treatment, cosmetics, pharmaceuticals, livestock, detergent, aquaculture, household and hospital. In oilfield industry, benzalkonium chloride solution can control SRB bacteria development, algae propagation and sludge reproduction. At the same time, benzalkonium chloride has good properties of penetrating and dispersing. it can penetrate and remove sludge and algae in water flooding process. Benzalkonium chloride products can also be used in the formulation of pipeline corrosion inhibitors, De-emulsifiers and  sludge breakers for enhanced oil recovery process. In addition, benzalkonium chloride solution has advantages of low toxicity, soluble in water, no toxicity accumulation, convenient in use, unaffected by water hardness. Bichain is one of reliable benzalkonium chloride solution manufacturers and suppliers of benzalkonium chloride 50 disinfectant, DDBACBKC, BAC for oilfield water treatment. It has three CAS numbers: CAS 8001-54-5, CAS 63449-41-2 and CAS 139-07-1. We supply high quality BKC products like Empigen BAC 50 & 80, Preventol RI 50 & 80

Technical Data:
Benzalkonium Chloride BKC spec
Oil & Gas:
Benzalkonium chloride solution:
♦Control sulphate-reducing bacteria (SRB) activities in oil well, Avoid pitting of steel equipment and pipelines.
♦Control SRB and aviod oil well souring and the liberation of toxic H2S gas.
♦Used in water flooding for enhanced oil recovery through de-emulsification and sludge breaking.
Water treatment:
Benzalkonium chloride disinfectant based products are used in water & effluent treatment and as algaecides for swimming pools.
Disinfectant, detergent, sanitizer:
Due to its properties of non-toxic, non-tainting, non-corrosive, non-staining, benzalkonium chloride products are the main active ingredients in the formulation of disinfectants and bactericidal sanitisers for personal hygiene, healthcare, agriculture and food supply. BAC 50 & BAC 80 can be safely incorporated into hygiene products so as to enhance both penetration and removal of soil and surfaces disinfection.
Pharmaceutical & cosmetic:
Due to its safety, benzalkonium chloride 50 & 80 is widely used in a range of leave-on skin sanitisers and sanitary baby wipes. BAC 50 is widely used as a preservative in ophthalmic, nasal and aural pharmaceutical preparations as well as to optimise emolliency and substantivity in formulations.
Horticulture & household:
Benzalkonium chloride product is highly effective against mould, mildew, moss, fungi & algae and is used for cleaning and preparation of all types of surfaces like greenhouses, roofing, paths, wooden decking, sheds, masonry.
Benzalkonium chloride solution can reduce antibiotic requirement in aquaculture through improved hygiene. BAC is used for water treatment, fish parasite removal, general site disinfection and infectious disease prevention in fish & shellfish.
Timber protection:
Benzalkonium chloride biocide displays excellent fungicidal and algaecidal properties, and is highly effective against other organisms in combination formulations.
Pulp & paper industry:
Benzalkonium chloride disinfectant can be used as a general microbicide for slime control & odour management in pulp mills. It improves paper handling and imparts strength & antistatic properties to paper products.
Textile industry:
Benzalkonium chloride 50 & 80 can be used to protect natural fibres from mould and fungi and as a moth repellent. It also acts as a permanent retarder in the dyeing of acrylic fibres with cationic dyestuffs.
Leather industry:
Benzalkonium chloride products inhibits growth of mould & mildew on hides and facilitates softening, wetting & dyeing of leather.
Chemical industry:
Quaternary ammonium compounds have different applications in the chemical industry as precipitant, phase transfer catalyst due to its ability to localise at oil, water and air, water interfaces, emulsifier, de-emulsifier, etc.
Polymer & coatings:
Quaternary ammonium compounds are widely used as anti-static, emulsifier & preservative in the coatings industry (paints, wood treatment, electronics)
Package and Storage
Package: 200L plastic drum, IBC (1000L) or customers’ requirement. Store in dry cool and ventilation environment.
Shelf time: two years
Recommended Dosage
As nonoxidizing boicide, 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 product can 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 froth disappearance.
No blending with anion surfactant.
