Benzalkonium Chloride Applications

Industrial Applications of Benzalkonium Chloride (Alkyl Dimethyl Benzyl Ammonium Chloride)

Oil & gas Biocorrosion presents a major operational hazard for the oil and gas production industries. Benzalkonium chloride (BAC 50 & BAC 80) is used to control the activities of sulphate-reducing bacteria (SRB) in sulphate rich waters and cause deposition of ferrous sulphides which causes pitting of steel equipment and pipelines. SRB are also implicated in oil well souring, and responsible for the liberation of toxic H2S gas. Additional applications of Benzalkonium chloride include enhanced oil extraction through de-emulsification and sludge breaking.
Manufacture of disinfectants and detergent-sanitisers On account of its non-toxic, non-corrosive, non-tainting, non-staining characteristics, benzalkonium chloride is the main active use in the formulation of disinfectants and bactericidal sanitisers for   healthcare, personal hygiene, the public sector and to safeguard our agriculture and food supply. BAC 50 & BAC 80 allow microbicidal & cleaning properties to be safely incorporated into hygiene products to enhance both penetration and removal of soil & disinfection of surfaces.
Pharmaceuticals & cosmetics The safety factor of benzalkonium chloride allows its use in a wide 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.
Water treatment Benzalkonium chloride based formulations are used in water & effluent treatment and algaecides for swimming pools.
Aquaculture Benzalkonium chloride reduces 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 Global environmental concern has led to increasing replacement of persistent chlorinated biocides with safer, biodegradable benzalkonium chloride in wood protection. BAC displays excellent fungicidal and algaecidal properties, and is highly effective against other organisms in combination formulations.
Pulp & paper industry Benzalkonium chloride is 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 is used to protect natural fibres from the action of 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.
Horticulture & household Benzalkonium chloride is highly effective against mould, mildew, moss, fungi & algae and is used for cleaning and preparation of all types of surfaces: greenhouses, roofing, paths, wooden decking, sheds, masonry
Chemical industry Quaternary ammonium compounds have diverse applications in the chemical industry as precipitant, phase transfer catalyst on account of 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)
