Magnesium Sulfate

Magnesium Sulfate is an inorganic salt with the formula: MgSO₄. It is hygroscopic and most commonly encountered as magnesium sulfate heptahydrte, MgSO₄ * 7H₂O, or Epsom salt: a health, beauty, and bath salt. Due to its water-attracting properties, magnesium sulfate is used as a desiccant.

Applications of magnesium sulfate include: feed/fertilizer ingredient, food ingredient, pharmaceutical additive, paper processing, and it has several useful functions as a chemical precursor, catalyst, desiccant, and flocculator.

Agriculture
In agriculture, magnesium sulfate is used in feed, feed-premixes, and fertilizers as a source of magnesium and sulfur, both important elements for plant growth and development.

Additional Notes:
* Epsom salt is the heptahydrate of magnesium sulfate.
* Anhydrous magnesium sulfate is most easily prepared by the dehydration of magnesium sulfate hydrates.
