The differences between povidone iodine and iodophor are different in composition, sterilization time and scope of use. The specific analysis is as follows:

1. Different components: povidone iodine and iodophor are complexed iodine strictly, but the composition of complexing agent is different. Iodophor is complexed by chlorhexidine alcohol and iodine plus surfactant, while povidone iodine is complexed by iodine and PVP. The effective iodine concentration of iodophor is 0.2%, while that of povidone iodine is 5% - 1%.

2. Different sterilization time: Povidone iodine is a composite iodine agent, which has the advantage of continuously and slowly releasing iodine solution, so it has a long-term bactericidal effect on wounds. But iodophor may volatilize in half an hour.

3. Different scope of use: Povidone iodine, as a disinfectant and antiseptic, is mainly used to treat vaginal infection, skin infection, oral infection, etc. It can also be used for skin disinfection and mucous membrane flushing. Iodophor has broad-spectrum bactericidal effect and can kill bacterial propagules, fungi, protozoa and some viruses. It is used as a bactericidal disinfectant in medical treatment, and can be used for the disinfection of skin and mucous membrane, as well as for the disinfection of trichomonal vaginitis, fungal vaginitis, skin fungal infection and other diseases. It can also be used to disinfect the skin of injection site and instruments before operation.
