Usage: Used in industries, engineering plastics, agricultural fertilizers, daily chemical industries, and other fields.

Magnesium sulfate is a multifunctional compound that has wide applications in various fields such as industry, agriculture, animal husbandry, and daily life. The magnesium element it contains is crucial for plant growth. As the central element of chlorophyll, it participates in photosynthesis, promotes carbohydrate metabolism, nucleic acid synthesis, and phosphate conversion. It is also a key component for protein synthesis and genetic material transfer. In agriculture, magnesium sulfate is used as a fertilizer to provide sulfur and magnesium elements, promote crop growth, increase yield, and improve soil structure. Lack of these elements may lead to symptoms such as crop discoloration, leaf shrinkage, and the appearance of spots. In animal husbandry, magnesium sulfate increases the milk production and quality of animals such as cows by supplementing magnesium in feed and drinking water. In daily life, magnesium sulfate is used in foot bath and shower gel to remove athlete's foot, reduce muscle hardness, and eliminate fatigue. It is also used in shampoo to reduce hair oiliness and make hair soft. It can also be used for artificial snow making. In industry, magnesium sulfate is used as a synthetic additive in the production of ABS and PVC resins, papermaking, printing and dyeing, and is also an important additive for monosodium glutamate and yeast fermentation. Anhydrous or low water magnesium sulfate serves as an efficient desiccant for organic synthesis intermediates and feed and fertilizers, demonstrating its irreplaceability in multiple industries.
