Benzalkonium chloride powder (Abbreviation: BAC) belongs to the quaternary ammonium salt class of compounds. As a cationic surfactant broad-spectrum fungicide, it can effectively control the reproduction of bacteria and algae in water and the growth of sludge, and has good sludge stripping effect and certain dispersion and penetration effects. At the same time, it has certain oil removal, deodorization ability and corrosion inhibition effect.

What is the bactericidal performance of benzalkonium chloride?
Benzalkonium chloride is a non oxidizing fungicide that dissociates into cationic active groups in aqueous solution. It has a clean and bactericidal effect, strong and rapid bactericidal power, low toxicity, and minimal irritation to the skin and mucous membranes. It can change the permeability of bacterial cytoplasmic membranes, causing the leakage of bacterial cytoplasmic substances and hindering their metabolism, thus exerting a killing effect. In clinical practice, both benzalkonium chloride and benzalkonium bromide are commonly used cationic surfactants as broad-spectrum fungicides. They dissolve slowly in water and are easily soluble in ethanol and acetone. However, pure benzalkonium chloride is still the preferred choice because it is easier to handle in aqueous solutions. Benzalkonium chloride solution is mainly used clinically for disinfection of skin, wounds, mucous membranes, and surgical instruments; It has a strong effect on Gram positive bacteria and is ineffective against Pseudomonas aeruginosa, acid fast bacteria, viruses, and bacterial spores. In addition, it can rapidly bind to proteins and its effect is significantly reduced in the presence of blood, cotton, cellulose, and organic matter.
What should we pay attention to when using this product?
The advantage of benzalkonium chloride over ethanol or hydrogen peroxide based disinfectants is that when applied to injured skin, the disinfectant made from this product does not cause a burning sensation on the skin.
In clinical practice, benzalkonium chloride eye drops are often assigned the task of sterilization, with a typical concentration range of 0.004% to 0.01%. In fact, benzalkonium chloride also has the function of a surfactant, which dissolves lipids in the tear film and increases drug permeability,.
However, it should be noted that although benzalkonium chloride has been commonly used as a fungicide in eye medications throughout history. However, the eye toxicity and irritation of this product cannot be ignored, especially if the concentration range is not appropriate, it will cause serious corrosiveness and irreversible damage to the corneal endothelium. So, in order to meet the health needs of consumers, many pharmaceutical companies have increased the production of drugs that do not contain benzalkonium chloride fungicides, or replaced them with less harmful fungicides.
