Magnesium Sulfate (Epsom Salt)

Univar Solutions is the premier distributor of magnesium sulfate in the United States

Magnesium sulfate (Epsom Salt) is a chemical compound, a salt with the formula MgSO4, consisting of magnesium cations Mg2+(20.19% by mass) and sulfate anions SO2−4. It is a white crystalline solid, soluble in water but not in ethanol. Magnesium sulfate is usually encountered in the form of a hydrate MgSO4·nH2O, for various values of n between 1 and 11. The most common is the heptahydrate MgSO4·7H2O, known as Epsom salt, a household chemical with many traditional uses, including bath salts.

Univar Solutions offers magnesium sulfate in multiple forms and packaged options.  Our relationships with all major producers around the world combined with our national distribution network offer our customers fast and reliable accessibility to meet your magnesium sulfate needs efficiently and quickly.
