Tincture of iodine is a disinfectant, usually 2-7% elemental iodine, along with potassium iodide or sodium iodide, dissolved in a mixture of ethanol and water. As in the case of Lugol's iodine, the role of iodide and water in the solution is to increase the solubility of the elemental iodine, by turning it to the soluble triiodide anion I3-. However, since iodine has moderate solubility in ethanol, it is also assisted by this solvent directly.

Thus, iodine tincture solutions are characterized by the presence of alcohol, and about the same amount (weight % content) of elemental iodine as iodide. Lugol's iodine, by contrast, has no alcohol, and has twice the amount of iodide as elemental iodine.
