Magnesium sulphate heptahydrate
Molecular formula: MgSO4.7H2O
Property: Anhydrous magnesium sulphate is used as a drying agent. Since the anhydrous form is hygroscopic (readily absorbs water from the air) and therefore harder to weigh accurately, the hydrate is often preferred when preparing solutions, for example in medical preparations. Epsom salts have traditionally been used as a component of bath salts.

Benefits:
Not containing any toxic substance, it can be used for medicine, fertilizer, leather, printing, pigment, porcelain, match, explosive, fireproof material and additives for magnesium salts and feedstuff. It is a raw material for the production of compounding fertilizer. Plant fed with magnesium compounding fertilizer will grow 15-50% quicker than that fed with compounding fertilizer without magnesium. It can be used to prepare medicines such as cathartic, magnesium trisilicate and acetyl spiramycin etc. In food industry, it can be used for lactic acid and monosodium glutamate etc. Also for dyestuff, weight solvent, and magnesium stain. In addition, it is used for sewage treatment through precipitation.
