A method for preparation of iodizing agent for the use in the formulation of iodized salt that offers excellent stability of iodine in iodized salt is developed and the unrefined salt iodized with this compound was tested for its stability in presence of moisture, temperature and metal salts at higher temperature. The hydrotalcite type layered compound was used to prepare such compound and part of carbonate was substituted with iodate anion. The iodizing agent exhibited excellent stability of iodine in iodized salt.
