Application areas


Magnesium sulphate anhydrous and epsom salt are used as cost-effective production accessories and unproblematic coagulants in the production of thermoplastics such as ABS plastics (acrylonitrile butadiene styrene), which are used across the globe. The big advantage is the lower corrosion level compared to other salts.


Magnesium sulphate anhydrous, epsom salt, potassium chloride and potassium sulphate are used as micronutrients in biotechnological procedures. Typical areas of application are yeast production as well as fermentation reactions for the production of proteins, enzymes, ethanol, vitamins, etc.


Hide salt special is ideal for the traditional preservation and preparation of cow, calf and pig skin as well as sheep skins. The excess water is removed from skins by using hide salt. The salt also has an antibacterial effect and protects the hides from decay. These quality characteristics benefit the suitability of storage and ensure the best possible preparation for the tanning process. Industrial salt is an important element in drilling fluids primary used in the exploration and extraction of crude oil and natural gas. The use of industrial salt is suitable for the stabilisation of the borehole as well as the lubrication and cooling of the drilling head. In the refining process of petroleum products—e.g. in the Merox process—industrial salt is applied in the filtration of the final product.

Magnesium sulphate anhydrous and epsom salt make leather suppler. They also play a role in tannin-based bonding and increase weight.


Magnesium sulphate anhydrous and epsom salt are essential to the spin baths conducted in the process of making rayon fibers.

Detergents and cleaning agents

As an ingredient of heavy-duty detergents, magnesium sulphate leads to a fibre-friendly effect and a neutral behaviour towards waste water. Magnesium sulphate and magnesium chloride solution are used in liquid soaps, detergents and rinsing agents to regulate viscosity. Industrial salt is used as the basic material for detergent processing.
