Performance and use

Benzalkonium chloride is a cationic surfactant. It is a non-oxidizing fungicide, which can be used as benzalkonium chloride disinfectant. It has a broad-spectrum and high-efficiency bactericidal and algae-killing ability. It can effectively control the reproduction of fungi and algae in the water and the growth of slime. A certain degree of dispersion and penetration, at the same time, it has a certain ability to remove oil, deodorize and inhibit corrosion.

Benzalkonium chloride has low toxicity, no cumulative toxicity, and is easily soluble in water and is not affected by water hardness. Therefore, it is widely used in circulating cooling water systems in petroleum, chemical, power, textile and other industries to control circulating cooling water systems The growth of bacteria and algae has a special effect on killing sulfate reducing bacteria.

Benzalkonium chloride can be used as a bactericidal and mildewproof agent and softener, antistatic agent, emulsifier, and conditioning agent in the textile printing and dyeing industry.


Benzalkonium chloride, as a non-oxidizing bactericidal and algaecide agent, is generally dosed at 50-100 mg / L; as a slime stripping agent, the dosage is 200-300 mg / L, and an appropriate amount of silicone defoamer can be added when needed. Benzalkonium chloride can be used in combination with other fungicides, such as isothiazolinone, glutaraldehyde, dithiocyanatomethane, etc., which can play a synergistic effect, but it cannot be used together with chlorophenols. After the addition of benzalkonium chloride, the dirt in the circulating water due to stripping should be filtered or removed in time to prevent the foam from depositing after it disappears. Do not mix Benzalkonium chloride with anionic surfactants.

Benzalkonium chloride specifications

Our benzalkonium chloride solution has 44%, 50% and 80% active contents. Generally speaking, 80% is used for export and 44% and 50% is used for domestic sales.

Security and protection

Benzalkonium chloride has a slightly almond odor and no obvious irritation to the skin. When contacting the skin, rinse with water.

Benzalkonium chloride coronavirus

Benzalkonium chloride is a typical dual-function disinfectant. It can not only kill bacteria and fungi, but also kill and inhibit viruses, and has a strong killing effect on a variety of pathogenic bacteria, fungi and viruses. Therefore, benzalkonium chloride can be widely used for disinfection in various places.

Benzalkonium chloride is easily adsorbed on the surface of negatively charged bacteria, changes the permeability of bacterial cytoplasmic membranes, ruptures the bacteria, and thus plays a killing role. Less than 500 mg / L benzalkonium chloride is commonly used in hand sanitizers and mucosal disinfectants. Studies have shown that low concentrations of benzalkonium chloride do not have the ability to inactivate coronavirus. Above 1g / L benzalkonium chloride has a mild effect of inactivating coronavirus, which takes 5 minutes.

Benzalkonium chloride pharmacological effects

Foreign countries have already begun to use benzalkonium chloride solution to fight coronavirus, and a large number of domestic and foreign literature and research have confirmed that benzalkonium chloride has the following pharmacological effects:

  1. Broad spectrum killing of pathogenic bacteria:

In vitro studies confirmed that benzalkonium chloride has significant killing of E. coli, Staphylococcus aureus, Pseudomonas aeruginosa, Enterococcus faecalis, with a minimum bactericidal concentration of 0.0125%, a minimum bacteriostatic concentration of 0.00625%, and a bactericidal rate of 100% within 24 hours.

  1. Broad spectrum fungicidal effect:

Benzalkonium chloride can significantly kill fungi such as Candida albicans and Aspergillus niger. The minimum bactericidal concentration is also 0.0125%, and the sterilization rate is 100% within 24 hours.

  1. Broad spectrum inhibition and killing of viruses:

A number of foreign studies have confirmed that benzalkonium chloride is effective against SARS, MERSr-CoV, influenza viruses (A and B), parainfluenza viruses (PSV-1, 2, 3), avian influenza viruses (H7N9,), Newcastle disease , Bursal disease virus, adenovirus, HIV virus, HSV-2, enterovirus, cytomegalovirus, BK virus, poliovirus (PV), Coxsackie virus, Ebola virus, minimum kill concentration 0.00125%, incubation with the above virus in vitro for 1-5 minutes, the virus killing rate exceeds 95%, the effect is 5 minutes, can inactivate the replication activity of SARS CoV, its antiviral activity is significantly better than sodium hypochlorite (84 disinfectant).
