Food Additive 14989-29-8 Magnesium Chloride Hexahydrate

Physicochemical properties

Pure magnesium chloride is colorless monoclinic crystal, industrial products are usually yellowish brown, with bitter and salty taste. It is easy to absorb moisture and loses 2 molecules of crystal water when dissolved in water at 100 ℃. At normal temperature, its aqueous solution is neutral. It begins to lose part of hydrogen chloride and decompose at 110 ° C, and the strong heat turns into oxychloride, which decomposes when heated rapidly at about 118 ° C. Its aqueous solution has an acidic melting point of 118 ° C (decomposition, hexahydrate) and 712 ° C (anhydrous).
