Calcium iodate (also called lautarite) is a compound of calcium and iodate anion. Its formula is Ca(IO3)2. It is used as a dough conditioner. Calcium iodate is an oxidant, hence it is added to lotions and ointments as an antiseptic and deodorant.[1] It can also be used as an iodine supplement in chicken feed. It may be formed by the anodic oxidation of calcium iodide or by passing chlorine into a hot solution of lime in which iodine has been dissolved.
