The Difference Between Povidone Iodine And Povidone Iodine

There are similarities as well as differences between povidone-iodine and povidone-iodine, both of which are a disinfectant. Strictly speaking, povidone-iodine and iodophor are both complexed iodine, mainly because the composition of the complexing agent is different. Povidone-iodine is a big name, and povidone-iodine is the most commonly used variety of povidone-iodine. Iodophor is formed by the complexation of chlorhexidine alcohol and iodine plus surfactant, while povidone-iodine is formed by the complexation of iodine and PVP. 

The available iodine concentration of iodophor is 0.2%, while that of povidone-iodine is 5%-1%. The objects used are different. Iodophor is a skin disinfectant, while povidone-iodine is a skin and mucous membrane disinfectant. The bactericidal effect is also different, iodophor is stronger than povidone-iodine. Povidone-iodine exerts its antibacterial effect by continuously releasing free iodine. Its mechanism of action is to denature and kill the protein of bacteria, and it is effective against bacteria, fungi, and viruses. It has strong broad-spectrum bactericidal power, low toxicity, and almost no irritation and corrosion. In addition, povidone iodine also has an oral solution, but it is suitable for the disinfection of livestock, especially turtles.
