A germicidal iodine composition comprising an aqueous solution of elemental iodine in a germicidally effective amount not exceeding about 1.0% and at least one organic substance which slowly reacts with iodine selected from the group consisting of iodine complexing polymers, surface active agents, alcohols, polyols and water soluble solvents, said organic substance constituting 1 to 50% by weight of said composition, wherein iodine loss during extended storage due to such reaction is controlled by providing in said composition balanced sources of iodide ion in the range of about 0.025% to 0.5% and iodate ion in the range of about 0.005% to 0.2% while maintaining a pH within the range of pH 5-7.
