With mechanism: PVP is a kind of hydrophilic polymers, itself has no antibacterial effect, but because of its effect on the membrane affinity, iodine will lead directly to the bacterial cell surface, it is meaningful to improve the antibacterial activity of iodine. Iodine into the attack target is bacterial cytoplasm and cytoplasmic membrane, immediately within a few seconds to kill bacteria. When hydrophobic compounds, peptides, proteins, lipids and cytosine necessary for biological molecules after contact with PVP -i oxidation by iodine or iodide immediately, make the loss of activity, to achieve a longer antiseptic effect.
