Explanation-Sodium Iodate is an inorganic salt that is intended for use as an oxidizing agent in cosmetics, but no current uses have been reported. It is approved by the European Union for use as a preservative in rinse-off cosmetic products at concentrations no greater than 0.1%. Pure Sodium Iodate is a sufficiently strong oxidizing agent that it presents a fire risk near organic material, and it can react violently with aluminum, arsenic, carbon, copper, hydrogen peroxide, phosphorous, potassium, sulfur, and metal sulfides. Sodium Iodate is toxic to the retina; injection of 10^-4 M Sodium Iodate into the vitreous of rabbit eyes inactivated the electroretinogram in 1 day. Acute toxicity studies in mice show that concentrations of 505 mg/kg delivered orally is expected to cause convulsions and death in half the animals.
