ABSTRACT OF THE DISCLOSURE An improved iodine tincture is provided by incorpor- ating therein a small amount, preferably about 0.25 to 2.5 parts per part by weight of iodine, of povidone, 1-vinyl-2 pyrrolidone polymer. In these proportions, the povidone modified tincture of iodine exhibits markedly reduced tendency to burn or sensi- tize skin areas on which it dries, is stable, and at the same time retains the essential germicidal activity of unmodified tincture of iodine. The new products can be formulated directly or as concentrates yielding the improved tincture upon extension with a prescribed amount of aqueous-ethanolic diluent.
