Anhydrous magnesium Sulphate is commonly used as a desiccant in organic synthesis due to its affinity for water. In pulp production, anhydrous MgSO4 is used to increase selectivity in oxygen delignification, as well as in peroxide- and oxygen-supported bleaching stages. In the chemical industry MgSO4 anhydrous is used as a very versatile raw material for producing other magnesium compounds. MgSO4 anhydrous is also applied as a stabilising agent for bleaching agents such as peroxides and perborates, which are commonly used in detergents.
