Product Features

Benzalkonium Chloride(DDBAC/BKC) is one of the Quaternary ammonium class of Cationic surfactants, belonging to nonoxidizing biocide. Benzalkonium Chloride(DDBAC/BKC) is widely used as a disinfectant in the Hospital, Livestock and Personal Hygiene sectors. Dual biocidal and detergency properties ensure high efficacy against Bacteria, Algae and Fungi and enveloped Viruses at exceptionally low ppm concentrations. Benzalkonium Chloride(DDBAC/BKC) also has dispersing and penetrating properties, with advantages of low toxicity, no toxicity accumulation, soluble in water, convenient in use, unaffected by water hardness. Benzalkonium Chloride(DDBAC/BKC) can be also used as anti-mildew agent, antistatic agent, emulsifying agent and amendment agent in woven and dyeing fields.

Polymer & Coatings Benzalkonium Chloride(DDBAC/BKC) is widely used as an Anti-Static, Emulsifier & Preservative in the Coatings Industry (Paints, Wood Treatment, Electronics)
Chemical Industry Benzalkonium Chloride(DDBAC/BKC) has diverse applications in the Chemical Industry as Precipitant, Phase Transfer Catalyst, Emulsifier/De-Emulsifier, etc.
Water Treatment Benzalkonium Chloride(DDBAC/BKC) is used in Water & Effluent Treatment Formulations and Algaecides for Swimming Pools
Aquaculture Benzalkonium Chloride(DDBAC/BKC) reduces the requirement of harmful Antibiotics in Aquaculture through improved hygiene. Used for Water Treatment, General Site Disinfection, Fish Parasite Removal, Prevention of Infectious Disease In Fish & Shellfish.
Timber Protection Global environmental concern has led to increasing replacement of chlorinated biocides with safer, biodegradable Benzalkonium Chloride(DDBAC/BKC) in Wood Protection. It displays excellent fungicidal and algaecidal properties, and is highly effective against other organisms in combination formulations.
Pulp & Paper Industry Benzalkonium Chloride(DDBAC/BKC) is used as a General Microbicide for Slime Control & Odour Management, and improves Paper Handling (Imparts Strength & Antistatic properties)
Textile Industry Benzalkonium Chloride(DDBAC/BKC) solutions are used as Moth Repellents, Permanent Retarders in Dyeing of Acrylic Fibres with Cationic Dyestuffs.
Leather Industry Benzalkonium Chloride(DDBAC/BKC) inhibits growth of Mould & Mildew on Hides. Facilitates Leather Softening, Wetting & Dyeing.
Horticulture & Household Benzalkonium Chloride(DDBAC/BKC) 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

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. Benzalkonium Chloride(DDBAC/BKC) 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.

Benzalkonium Chloride(DDBAC/BKC) can not be blending with anion surfactant.
