Iodophor is a type of disinfectant water. Commonly used disinfectant waters include iodophor, hydrogen peroxide, iodine, and alcohol. Povidone-iodine is an indeterminate combination of monomeric iodine and polyvinylpyrrolidone (Povidone). Medical povidone iodine is usually low in concentration (1% or less) and is light brown in color. Povidone Iodine has a broad-spectrum bactericidal action, killing bacterial propagules, fungi, protozoa and some viruses. It can be used medically to disinfect skin, mucous membranes, and to treat various infected wounds. Sterilized water is a general term for solutions that can play a role in disinfection, and there are many types. According to the clinical role can be divided into skin and mucous membrane disinfectant; instrument disinfectant and environmental disinfectant and so on. There is no point in comparing iodophor and disinfectant water, which contains iodophor solution. The specific choice of disinfectant water needs to be selected according to the requirements of use.
