  • Description

    Magnesium sulfate heptahydrate, also known as thiosulfate, bitter salt, laxative salt, or laxative salt, with a chemical formula of MgSO4 · 7H2O, is a white or colorless needle shaped or oblique columnar crystal, odorless, cool and slightly bitter. Heat decomposition gradually removes crystalline water and turns into anhydrous magnesium sulfate. Mainly used in the manufacturing of fertilizers, leather making, printing and dyeing, catalysts, papermaking, plastics, porcelain, pigments, matches, explosives, and fire-resistant materials. It can be used for printing and dyeing thin cotton fabrics and silk, as a weighting agent for cotton fibers and a filler for kapok products. In medicine, it is used as a laxative salt.


    Application

     food
    As a food fortifier. China's regulations stipulate that it can be used for dairy products, with a dosage of 3-7g/kg; The dosage used in liquid and dairy beverages is 1.4-2.8g/kg; The maximum usage amount in mineral beverages is 0.05g/kg.


     Industry
    It is often used in conjunction with calcium salts in the water used for yeast. Adding 4.4g/100l of water can increase the hardness by 1 degree, but excessive use can produce a bitter taste and a hydrogen sulfide odor.
    Used for leather making, explosives, papermaking, porcelain, fertilizers, as well as oral laxatives in medicine, mineral water additives, etc.
    Agriculture
    Magnesium sulfate is used as a fertilizer in agriculture because magnesium is one of the main components of chlorophyll. Usually used for potted plants or magnesium deficient crops such as tomatoes, potatoes, roses, etc. The advantage of magnesium sulfate over other fertilizers is its high solubility. Magnesium sulfate is also used as a bath salt.
