Pharmacologic action:
As a cationic surfactant, this product is a quaternary ammonium compound, which has good bacteriostatic effect on bacteria, fungi and yeast. As a medicinal excipient, benzalkonium chloride is commonly used in ophthalmic preparations and is an efficient antibacterial preservative. It is a broad spectrum fungicide, which can change the bacterial cytoplasmic membrane permeability, make the bacterial cytoplasmic substance extravasate, hinder its metabolism and play a killing role. It had strong effect on gram-positive bacteria, but had no effect on pseudomonas aeruginosa, acid-fast bacilli and cell buds. It can rapidly bind to protein, and its effect is significantly reduced in the presence of blood, cotton, cellulose and organic matter. Concentrations below 0.1% are not irritating to skin.

product Usage:
Benzalkonium chloride is mainly used for mucous membrane disinfection at the surgical site, skin mucosal wound disinfection, infected skin disinfection and vaginal irrigation. It should be noted that this product can only be used externally, not for internal administration or enema. In addition, it can not be used in mucosal wound or inflammation for a long time or a large area.
Benzalammonium chloride is dissociated into cationic active groups in aqueous solution, which has the function of cleaning and sterilization. Widely used in sterilization, disinfection, anti-corrosion, such as flowers, descaling, solubilization and other aspects, is also a cationic dye dyeing acrylic fiber levelling agent.




Application Field:
Widely used in compound disinfectant 'disinfection wipes, disinfection of medical and surgical instruments, environmental disinfection, disinfection and antiseptic cosmetics, eye drops, nose drops, etc. It can be used as antiseptic and softener, antistatic agent, emulsifier and conditioner in textile printing and dyeing industry.


Product Characteristics:
Benzalkonium chloride is a cationic surface active agent, a non-oxidizing bactericide, with a broad spectrum and efficient bactericidal and algicidal ability, can effectively control the growth of bacteria and algae in water and slime growth, and has good slime stripping and certain dispersion, permeability, and a certain ability to remove oil, deodorization and corrosion inhibition. Soluble in ethanol and acetone. Although it dissolves slowly in water, an aqueous solution is preferred because it is easier to work with. The aqueous solution should be neutral to slightly alkaline and colorless to light yellow in color. An aqueous solution foams when shaken and has a bitter and faint almond taste in a concentrated solution.




Using Method:
Benzalammonium chloride solution is a kind of skin disinfectant, which is generally used for skin anti-inflammatory and local disinfection in clinic. Especially for some genitalia and infected skin parts disinfection and cleaning use.If used on ordinary smooth skin, the ratio is generally 0.1% concentration. However, if it is applied to the skin mucous membrane, such as the genitalia or the skin tissue of the mouth and lips, the solution concentration can be matched to 0.05%. After matching the concentration of these drugs, you can scrub the skin directly on the part of the skin, generally scrubbing for 3-5 minutes.


Package & Storage:
25kg/drum (powder/solution) , 200kg/drum ( solution)
Keep out of light and sealed.
