(Benzalkonium Chloride) (DDBAC/BKC)

  • CAS No. 8001-54-5 or 63449-41-2, 139-07-1
  • Molecular weight: 340.0
  • Molecular Formula: C21H38NCl

Properties:

DDBAC/BKC is a kind of the Quaternary ammonium class of Cationic surfactants, which belongs to nonoxidizing biocide. It has a broad-spectrum and high-efficiency sterilization  ability, can effectively control the growth of algae and slime in the water.

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. It plays a good role in the release of mud and  has deodorant ability and corrosion inhibition. 

It is widely used in petroleum, chemical, power, textile and other industries in the circulating cooling water system, to control the bacteria Algae breeding in circulating cooling water system.

It can be also used as anti-mildew agent, antistatic agent, emulsifying agent and amendment agent in woven and dyeing fields.

It is also 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.

SPECIFICATIONS:

  • Appearance: Colorless to yellowish transparent liquid
