Magnesium Sulfate Heptahydrate appeared as clourless pillar or needle crystal, with its formula MgSO4·7H2O,and molecular weight 246.47. It is odourless, taste cool, salty, bitter, relative gravity: 2.65, steady in under 48℃ moisture air. When it is in warm and hot air, it easily effloresce, easily solublein water (119.8%, 20℃) and glycerine, insoluble in ethanol. PH=7.0.
In food industry, it is used as nutritional supplement, solidification, the flavor increase, process helper, brew additive. when adding Magnesium in brew water,as nutritional supplement to improve ferment in brew, the improvement of the synthesizes drink taste(0.002%); adjusting the aqueous degree of hardness
In agriculture, it is used as weight additive for cotton, silk, filling for kapok products, evacuant for porcelain, fuels and fireproof materials, additive for brewing. It is also used in rayon and textile industry. It belongs to feedstuffs grade.
Storage and Transport: It should be stored in a dry, ventilative and clean warehouse, kept away from moisture and hot, futhermore. It should be stored separately from poisonous.
Packing: It is packed with polyethylene bag as inner, and a composite paper bag as the outer layer. The net weight of each bag is 25kg.
