Improved aqueous, ready to use iodine teat dip compositions are provided which are specially formulated for winter time use to permit application to cows teats without freezing while at the same time affording adequate germicidal activity. The compositions include from about 0.01-2 % by weight iodine, from about 0.01-3 % by weight iodide ion, and from about 35-75 % by weight of an additive selected from the group consisting of glycerin and a mixture of at least about 10 % by weight glycerin based upon the total weight of the composition and one or more C2-C7 polyhydric alcohols different than glycerin and each containing at least 2 hydroxyl groups, said composition containing no more than about 45 % by weight propylene glycol when propylene glycol is one of said polyhydric alcohols. The compositions preferably have free iodine values of from about 1-60 ppm at 25° C and from about 0.5-20 ppm at 4° C. |
