General

What is Magnesium Sulphate Heptahydrate? Also known by alternate names such as Epsom Salt (when hydrated), Magnesium Sulfate Heptahydrate, and Magnesium Sulphate, it is a crystalline compound commonly used in industrial, agricultural, and pharmaceutical applications. The heptahydrate form, contains seven molecules of water of crystallisation per molecule of magnesium sulphate and has the chemical formula MgSO₄·7H₂O. This highly soluble and versatile compound is valued for its ability to supply magnesium and sulphate ions, which are essential for numerous biological and chemical processes. It is used across various sectors, including healthcare, agriculture, water treatment, and manufacturing.

Consistent Quality: We use only carefully sourced Magnesium Sulphate Heptahydrate, meeting the standards of the American Chemical Society (ACS), ensuring reliable and consistent performance for a wide range of industrial, agricultural, and pharmaceutical applications.

Frequent Uses

Pharmaceutical and Nutraceutical Applications
Commonly used in the pharmaceutical industry for intravenous or oral administration as a source of magnesium. It is used in medical treatments for magnesium deficiency, eclampsia, and as a laxative. It is also a key ingredient in formulations for treating certain conditions related to the gastrointestinal and cardiovascular systems.

Agricultural Applications
Widely used as a fertiliser to address magnesium and sulphur deficiencies in soil. This helps to improve plant health, enhance photosynthesis, and promote enzyme activity. It is especially beneficial for crops such as potatoes, tomatoes, and other vegetables that require high magnesium and sulphur levels.

Water Treatment
Used in water treatment to purify and improve water quality. It helps in the removal of phosphorus and nitrogen, which can contribute to algae growth in water bodies. It is also used in the treatment of wastewater, particularly in processes that require the removal of impurities and contaminants.

Industrial Applications
Employed as a drying agent, stabiliser, or catalyst. Used in chemical manufacturing, textile production (as a mordant for dyeing), and in the production of detergents. Its ability to absorb water and stabilise reactions makes it valuable in a range of applications.

Cosmetic and Personal Care
Utilised in personal care products such as bath salts, body scrubs, and foot soaks. It is known for its therapeutic properties, particularly in soothing sore muscles and reducing inflammation. It is also used in some hair care products to improve hair strength and overall health.

Chemical Synthesis
Serves as a source of magnesium and sulphate ions. It is used in laboratories and industrial settings for its role in facilitating chemical reactions or as a component in the production of other chemical compounds
