- Magnesium sulfate heptahydrate is a chemical compound obtained from the evaporation of mineral waters, appearing as white crystals.
- Magnesium sulfate heptahydrate does not dissolve equally in all liquids; it dissolves well in water and glycerol, but poorly in alcohol.
- It is widely used in agriculture, pharmaceutical industry, cosmetics industry, textile industry, and detergent industries.
- In the agricultural industry, it is used as a raw material in the formulation of plant nutrition products and also directly as a fertilizer. It increases the sulfur and magnesium content in the soil. It is applied to potted plants or magnesium-deficient crops such as potatoes, carrots, tomatoes, peppers, lemons, and roses.
- To address magnesium deficiency, it is added to animal feed and used to regulate the digestive and excretory systems of animals.
- It helps remove substances such as ammonia, nitrile liquids, amines, chlorinated hydrocarbons, and acetone from water.
