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 used   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 mold 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)
