BAC 80 is a benzalkonium chloride solution (BAC 80%) which is a member of the quaternary ammonium based biocides. Comparing with BAC 50, BAC 80 has a higher concentration of benzalkonium chlorideAs a cationic surfactant, the biocidal efficacy of BAC 80 depends on its capacity in binding to intracellular membranes and disrupting cellular biochemical processes. Disruption of these processes ensures BAC 80 with a high level of activity against algae, bacteria, enveloped viruses and fungi at exceptionally low concentrations. BAC, major active content of BAC 80 has pass the stringent european standard of BS EN 1276 microbicidal testing. Bichain is one of reliable BAC 80 manufacturers and suppliers of benzalkonium chlorideActicide BAC 80, BAC 80% solution for oilfield water treatment. It has three CAS numbers: CAS 8001-54-5CAS 63449-41-2 and CAS 139-07-1. We supply high quality BAC 80 products like Empigen BAC 80 and Preventol RI 80.

Oil & Gas:
Benzalkonium chloride (BAC 80 & BAC 50):
♦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 (BAC 80 & BAC 50) 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 is the main active ingredient in the formulation of disinfectants and bactericidal sanitisers for personal hygiene, healthcare, agriculture and food supply. BAC 80 & BAC 50 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 (BAC 80 & BAC 50) is widely used in a range of leave-on skin sanitisers and sanitary baby wipes. BAC 80 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 (BAC 80 & BAC 50) 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 (BAC 80 & BAC 50) 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 (BAC 80 & BAC 50) displays excellent fungicidal and algaecidal properties, and is highly effective against other organisms in combination formulations.
Pulp & paper industry:
Benzalkonium chloride (BAC 80 & BAC 50) 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 (BAC 80 & BAC 50) 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 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.
