Abstract
Stable aqueous iodine/iodide/iodate germicidal compositions are provided which have relatively high quantities of free iodine therein and also substantially maintain the starting amounts of available and free iodine throughout a storage period of at least about three months. The compositions of the invention contain from about 0.01-1.4% by weight available iodine, from about 10-125 ppm free iodine, from about 0.005-0.5% by weight iodate ion, from about 0.1-15% by weight of iodine complexing agent, from about 0.004-0.5% by weight iodide ion, and have a pH of from about 2.0-4.5.
