Magnesium Chloride Hexahydrate

Magnesium Chloride Hexahydrate

Classification: Magnesium Salt

CAS NO.:7791-18-6

Molecular Formula:MgCl₂.6H2O


Details

  Product Characteristics:

  Magnesium Chloride Hexahydrate is a white crystalline powder, flake or  granule, odorless, slightly bitter in taste, and loose in texture. It is easily  soluble in water with slight heat release during dissolution, and also soluble  in organic solvents such as ethanol and acetone. It has strong hygroscopicity,  tends to deliquesce and agglomerate in humid air, and thus needs to be sealed  for storage. The aqueous solution is weakly acidic, with a melting point of  116-118℃; when heated to 110℃, it loses part of its crystal water and converts  into magnesium chloride dihydrate. It has stable chemical properties and can  react with substances such as alkalis and carbonates to form corresponding  magnesium salt precipitates.

  Applications:

  Agriculture and Animal Husbandry

  -In agriculture, it is used as a magnesium fertilizer to prevent and  control crop magnesium deficiency, promote photosynthesis. It is especially  suitable for cash crops such as vegetables and fruit trees, and can also improve  alkaline soil.

  - In animal husbandry, it serves as a feed additive to supplement magnesium  for livestock and poultry, maintaining electrolyte balance. In aquaculture, it  regulates the magnesium ion concentration in water bodies, supporting the  exoskeleton development of aquatic animals.

  Food and Pharmaceutical Industries

  -In the food industry, it acts as a coagulant for processing soybean  products like tofu and dried tofu. It is also added as a mineral supplement to  dairy products and sports drinks.

  - In the pharmaceutical field, it is used in the preparation of renal  dialysis fluid to regulate electrolyte balance in the human body.

  Other Fields

  - In cosmetics, it functions as a functional additive, mainly regulating  texture and enhancing stability.

  - When used in bath salts, it can adjust the texture of bath salts and  soothe the skin.

  - In the textile industry, it serves as a fixing agent and flame-retardant  auxiliary, improving the color fastness and fire resistance of textiles.

  - In water treatment, it acts as an auxiliary coagulant to help remove  suspended solids in water. It can also be used as a desiccant or deliquescent  agent, absorbing moisture from the environment by virtue of its  hygroscopicity.

  Packaging and Storage

  This product is packaged in PP bags, 25kg per bag, and can also be  customized according to user requirements. It should be sealed and stored in a  cool, dry place away from light, with a shelf life of twenty-four months.

  Safety Protection

  This product should be kept away from contact with eyes, skin, or clothing.  In case of splashing onto the body, immediately rinse with plenty of water.
