What is the difference between benzalkonium bromide and benzalkonium chloride?

Both of them are external disinfectants and broad-spectrum fungicides, which are suitable for disinfection of skin, mucosa, wounds and medical devices. However, benzalkonium bromide should be diluted before disinfection and use, that is, ready for use. The skin mucosa is 0. 1%, the wound is 0.0 1%, and it has a certain taste. Iodophor is 0. 1% solution, which can directly disinfect the skin. Before operation, use 0.2% solution to disinfect the skin. It is the most commonly used in hospitals at present, mainly used for skin disinfection and wound disinfection before registration and operation. It is not easy to dye and cause wound pain, and the disinfection effect is good, which has replaced the traditional alcohol iodine disinfection.
