Soft deliquescent crystals that are water-soluble. In a closed environment, a saturated aqueous solution of magnesium chloride will form an equilibrium at a relative humidity level of about 34% (20C). Magnesium chloride salt is also used for fireproofing wood, treating cotton and wool, as well as for the manufacture of parchment paper.
