What is Epsom Salt?

Epsom Salt, scientifically known as Magnesium Sulfate Heptahydrate, is a colorless, crystal compound highly valued for its uses in agriculture, healthcare, industry, and cosmetics. Rich in magnesium, it helps correct soil deficiency, soothe muscles, reduce swelling, and more, thanks to its excellent solubility in water.

How is it manufactured or produced?

Epsom Salt is produced through the evaporation of mineral-rich water, where the magnesium and sulfate crystallize into the compound we know. This process ensures a pure and effective product.
