1、Chemical Name：Magnesium Chloride

2、Molecular Formula: MgCl₂·6H₂O

3、Molecular Weight: 203.30

4、CAS: 7786-30-3

5、Character: It’s white or gray flake, easily soluble in water. In wet air, it’s easy to get deliquesced. At high temperature, it’ll decompose to hydrogen chloride and magnesium oxide.

6、Usage: It can be used to make tofu (bean curd). Tofu with brine (solution of Magnesium Chloride) is far more tender and delicious than with gypsum. It also can be used as food additives in other food industries.

7、Packing: It is packed with polythene bag as inner layer, and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg.

8、Storage and Transport: It should be stored in a dry and ventilative warehouse, kept away from heat and moisture during transportation, unloaded with care so as to avoid damage. Furthermore, it must be stored separately from poisonous substances.
