Sodium Selenite Uses

Sodium Selenite is a formaldehyde polymer. It is not a self-fixing agent and must be broken down into its constituent formaldehyde. This can be done by heating it or exposing it to basic conditions until it dissolves completely. Other applications include:

  • The primary use of Sodium Selenite, as well as related barium and zinc Selenites, is in the production of colorless glass.
  • Because Selenium is such an important mineral, Sodium Selenite is utilized in multivitamins and mineral supplements, whereas supplements containing only selenium utilize L-selenomethionine or a Selenium-enriched yeast.
  • The US Food and Drug Administration has approved a selenium supplement for animal diets; the most common form is Sodium Selenite for pet food.


Is Sodium Selenite Safe?

Selenium can be dangerous in large doses. The chronic toxic dose of selenium as Sodium Selenite for humans was estimated to be between 2.4 and 3 mg per day. The US Institute of Medicine set the adult Tolerable upper intake limits (UL) for selenium from all sources - food, drinking water, and dietary supplements - at 400 g/day in 2000. The European Food Safety Authority studied the matter and established a UL of 300 g/day.


How Is Sodium Selenite Made?
