Magnesium Sulfate Heptahydrate (CAS: 10034-99-8), widely known as Epsom salt, is a colorless crystalline inorganic salt combining magnesium, sulfate, and seven waters of hydration. Highly soluble in water and readily available at low cost, it serves as a concentrated and bioavailable source of magnesium and sulfate ions across agricultural, pharmaceutical, food, and industrial applications. In agriculture it corrects magnesium deficiency in soils and crops, supporting chlorophyll production and plant growth. The pharmaceutical and personal care industries use it as an osmotic laxative, bath additive for muscle relaxation, and magnesium supplement. Food-grade material functions as a firming agent and nutrient supplement, while industrial users rely on it in textile dyeing, paper production, water treatment, and as a precursor for other magnesium compounds. Its dependable quality, easy handling, and broad regulatory acceptance make magnesium sulfate heptahydrate a staple raw material in both consumer and industrial supply chains.

– Agriculture and Fertilizers: Applied as a fast-acting magnesium source in soils and foliar feeds to correct deficiency, enhance chlorophyll formation, and improve crop yield and quality.
– Pharmaceutical and Personal Care: Used as an osmotic laxative, magnesium supplement, and bath salt for relaxation, as well as an excipient in topical formulations.
– Food Processing: Employed as a firming agent in tofu and canned vegetables, a nutrient supplement, and a processing aid in beverage and dairy applications.
– Industrial Applications: Utilized in textile dyeing, leather tanning, pulp and paper processing, water treatment, and as a raw material for producing other magnesium salts.
