USP/EP/BP-grade Magnesium Sulfate (CAS 7487-88-9), anhydrous or heptahydrate (Epsom salt), supplied wholesale by Zyntex. For injections, laxatives, fertilizers, bath salts, food and feed. CoA and SDS with every lot.
Magnesium sulfate (MgSO4) is a white crystalline solid that dissolves easily in water. The heptahydrate, known as Epsom salt (MgSO4·7H2O), is the most common form, whereas the anhydrous form also serves as a laboratory drying agent.
Pharmaceutical companies use pharmacopoeia-grade magnesium sulfate in injections and infusions, for example in obstetric and emergency care, as well as in oral laxative preparations. Similarly, fertilizer producers use it as a soluble source of magnesium and sulfur for crops, and personal care producers use Epsom salt in bath salts. Food and feed producers also use it as a mineral source and processing aid.
Furthermore, other magnesium salts in our range include Magnesium Chloride, Magnesium oxide and Magnesium citrate.
