Two hydrates exist in saturated solution, the pentahydrate up to 19.85 °C and the monohydrate from 19.85-73.4 °C.

Other Classes -> Halogens, Inorganic Compounds

Cosmetic ingredients (Sodium Iodate) -> CIR (Cosmetic Ingredient Review)

Preservative

May react violently with aluminum; arsenic; carbon; copper; hydrogen peroxide; metal sulfides; organic matter; phosphorus; potassium; sulfur.

The safety of this ingredient has not been documented and substantiated. The CIR Expert Panel cannot conclude whether Sodium Iodate is safe for use in cosmetic products until the appropriate safety data have been obtained and evaluated.

Ingredients for which the data are insufficient and their use in cosmetics is not supported

Neurotoxin - Other CNS neurotoxin

Occupational hepatotoxin - Secondary hepatotoxins: the potential for toxic effect in the occupational setting is based on cases of poisoning by human ingestion or animal experimentation.

Nephrotoxin - The chemical is potentially toxic to the kidneys in the occupational setting.

Hemolytic anemia - Decreased hemoglobin or number of red blood cells.

ALTHOUGH OTHER OXIDIZING AGENTS HAVE NOT GENERALLY PROVED RETINOTOXIC, IT HAS BEEN SHOWN THAT INJURIOUS EFFECT OF IODATE IN EYE IS POTENTIZED BY OXIDIZING AGENT POTASSIUM PERMANGANATE, AND ANTAGONIZED BY REDUCING AGENT CYSTEINE, BUT NOT BY ADMINISTERING ASCORBIC ACID. /IODATE/
