essential information

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 area 
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.
 
AgricultureMagnesium 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.

The vehicle should be thoroughly cleaned after transportation.
Precautions for operation: Closed operation, strengthen ventilation. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear self-priming filter dust masks, chemical safety goggles, anti toxic work clothes, and rubber gloves. Avoid generating dust. Avoid contact with acids. Handle with care during transportation to prevent packaging damage. Equip with emergency response equipment for leaks. Empty containers may contain residual harmful substances. When the dust concentration in the air exceeds the standard, a self-priming filter dust mask must be worn. During emergency rescue or evacuation, a gas mask should be worn.
Storage precautions: Store in a cool and ventilated warehouse. Stay away from sources of fire and heat. It should be stored separately from acids and avoid mixing storage. The storage area should be equipped with suitable materials to contain leaked materials.
